Vertikalna tračna žagaVertical band saw
Področje, v katero spada izumFIELD OF THE INVENTION
Področie, v katero spada izum, je vertikalna tračna žaga z ogrod jem stroja, s sprejemom, ki ima izrez za žagin trak, za žagani material, kakor tudi z nosilcem koles, nameščenim v bistvu vertikalno, preko katerega nad In pod področjem materiala vrtljivo nameščenih koles, katerih vrtilna os je nameščena v bistvu horizontalno proti ravnini rezanja za kot, ki je enak ali manjši od 90°, teče brezkončni žagin trak In pri tem poteka nad in pod področjem materiala po vodilih, povezanih z nosilcem kolesa, za zasuk v ravnino rezanja, pri čemer sta žagin trak in material premakljiva v bistvu v horizontalno usmerjeno gibanje drug proti drugemu, za izvedbo delovnega hoda žaganja ter tako pride žagin trak z materialom na mestu zareza v vprijem žaganja.The field of the invention is a vertical band saw with a machine frame, a receptacle having a cutout for a saw blade, for a sawed material, as well as a wheel carrier mounted substantially vertically, through which, above and below the area of the material, rotatably mounted Wheels whose pivot axis is substantially horizontal to the cutting plane by an angle equal to or less than 90 °, runs an endless saw blade, passing above and below the material region by guides connected to the wheel carrier for rotation in a plane cutting, whereby the saw blade and the material are movable essentially in a horizontally directed motion towards each other, in order to carry out the working stroke of the saw, thus bringing the saw blade with the material at the point of the notch into the saw blade.
Stanje tehnike in tehnični problemState of the art and technical problem
Pri tovrstnih znanih vertikalnih tračnih žagah imajo vrtilne osi koles proti ravnini rezanja prednostni nagib 45°, pri čemer vendar ni podana pri tem nobena omejitev. Poleg tega so praviloma predvidena vpenjalna sredstva za material, ki so nameščena -za varno držanje materiala prednostno na obeh straneh ravnine rezanaja.In the case of such known vertical band saws, the rotary axes of the wheels have a tilt of 45 ° with respect to the cutting plane, but no limitation is given. In addition, material clamps are provided as a rule, which are mounted - to securely hold the material preferably on both sides of the cutting plane.
Znane vertikalne tračne žage dovoljujejo prerez žaganega materiala pri namestitvi ravnine rezanja prečno na smer podajanja materiala. Poševni rezi, pri katerih je ravnina rezanja proti smeri podajanja materiala zasukana, pri tem vendar niso možni.Known vertical band saws allow the cross-section of the saw material to be cut when positioning the cutting plane transversely to the feed direction. Oblique cuts where the cutting plane is rotated towards the feed direction but are not possible.
Po drugi strani omogočajo znane vertikalne tračne žage, pri katerih delovna miza ogrodja stroja ni opremljena z vpenjalnimi sredstvi, v določenem obsegu prostoročno žaganje, pri čemer se dovaja obdelovani kos materiala z roko pod odgovarjajočo kotno lego, podano z ravnino rezanja žaginega traku.On the other hand, they allow known vertical band saws, in which the workbench of the machine frame is not equipped with clamping means, to a certain extent hands-free sawing, with the machined piece of material being supplied by hand below the corresponding angular position given by the cutting plane of the saw blade.
Za izdelavo poševnih rezov uporabljamo hladne krožne žage, pri katerih lahko zasukamo žagin list in s tem ravnino rezanja v poševni kot.To make oblique cuts, we use cold circular saws, in which we can rotate the saw blade and thus the plane of cutting into the oblique angle.
Takšne hladne krožne žage imajo vendar pomanjkljivost, da je pesek materiala omejen z velikostjo radija žaginega lista proti možnostim vertikalne tračne žage imenovane vrste in s tern da krožni žagin list nima ravnega, marveč raje v obliki loka potekajoči rez, zaradi česar ni možno, izdelati ravne vreze, se pravi ne povsem skozi prežagane reze z ravno črto rezanja.Such cold circular saws have the disadvantage, however, that the sand of the material is limited by the size of the saw blade radius against the possibilities of the vertical band saw of this type and by the fact that the circular saw blade is not straight, but rather an arc-shaped incision, which makes it impossible to make a straight cuts, that is, not entirely through cut cuts with a straight cutting line.
Hladne krožne žage niso primerne v ostalem na noben način za prostoročno obdelavo oz. rezanje materiala obdelovanca na prej opisani način.Cold circular saws are not otherwise suitable for hands-free machining. cutting the workpiece material as described previously.
Opis rešitve tehničnega problema in izvedbenih primerov s seznamom slikDescription of the solution of the technical problem and examples with a list of pictures
Naloga izuma je zato tako konstruirati vertikalno tračno žago uvodoma imenovane vrste, da omogoča poleg izdelave ravnih rezov tudi izdelavo poševnih rezov in sicer s pozitivnimi in negativni4 mi poševnimi koti glede na smer podajanja materiala. Nadalje mora omogočiti v nadaljnji izvedbi prekinitev postopka rezanja, torej izdelavo delnih rezov z ravnim potekom rezanja. Pri tem naj izkazuje vertikalna tračna žaga kompaktno, enostavno sestavo, glede na obremenilne razmere zlasti lahko konstrukcijo in končno ureditev za zelo lahko rokovanje delov, povezanih s postopkom žaganja, pri čemer pa morajo ostati dosedanje možnosti vertikalne tračne žage zlasti glede na prej opisano prostoročno žaganje.It is therefore an object of the invention to construct a vertical band saw of the initially named type, in addition to making straight cuts, but also to making oblique cuts with positive and negative oblique angles depending on the direction of material feed. It must further enable the cutting process to be interrupted further, that is to say making partial cuts with a straight cutting course. The vertical band saw should have a compact, simple structure, particularly lightweight construction and final arrangement for very light handling of sawing parts, while keeping the current vertical band saw capabilities, especially with regard to the hands-free saw described above. .
To nalogo je po izumu v temelju lahko tako rešiti, da se zasuka nosilec kolesa okrog v bistvu vertikalne vrtljive osi ter da se lahko pritrdi v vsakem zasučnem položaju.According to the invention, this task can be solved fundamentally in such a way that the wheel carrier rotates about the substantially vertical rotary axis and that it can be fixed in any rotary position.
S tem ukrepom po izumu se lahko nastavi nosilec kolesa in s tem ravnina rezanja na različne poševne kote glede na smer podajanja žaganega materiala, ne da bi prišlo pri tem do premestitve težišča nosilca koles in s tem do s tem povezanih statičnih in vodilnih problemov, kajti nosilec kolesa ostane neodvisno od nastavitve različnih kotov poševnega rezanja statično vedno v svoji prvotni vertikalni ravnotežni legi, kar je zlasti važno za oblikovanje vodil Dornika nosilca kolesa..With this measure according to the invention, the wheel carrier and thus the plane of cutting can be adjusted to different oblique angles depending on the direction of delivery of the sawed material without any displacement of the center of gravity of the wheel carrier and the related static and guiding problems, because The wheel carrier remains static in its original vertical equilibrium position, regardless of the setting of the various oblique cutting angles, which is especially important for the design of the guides of the Dornik wheel carrier.
Nastavitev različnih nastavitev kota poševnega reza po izumu proti smeri podajanja materiala v navpični smeri rezanja vodi sicer k temu, da se nažaga material pri teh kotih poševnega rezanja poševno k črti plošče, čemur so se principialno doslej izogibali zaradi strahu pred nečistimi rezi. Vendar se je pokaza5 lo, da je povsem možen takšen poševni rez in da vodi k dobrim rezultatom.Adjusting the various settings of the slant angle of the invention according to the direction of feed of the material in the vertical direction of cutting otherwise causes the material to be inclined at such angles of slant to the line of the plate, which has in principle been avoided for fear of impure cuts. However, it has been shown that such an oblique incision is possible and leads to good results.
Zaradi odpada problemov pomika ravnotežja v zvezi z nastavitvijo poševnega reza nosilca koles obstoja sedaj tudi možnost, da izoblikujemo nosilec koles v lahki gradnji kot kompaktno enoto, ki vsebuje vse za pogon žaginega traku potrebne sestavne dele, ki izhajajo zaradi na nosilec koles s prirobnico pritrjenega pogonskega motorja, vodil za preusmeritev žaginega traku, krmiljenja in nastavitve rezilnih pogojev vključno za to potrebnih rokovalnih sredstev itd. S tem lahko izoblikujemo vertikalno tračno žago v bistvu kot iz nosilca koles vključno vseh za obratovanje žage potrebnih delov oblikovano gradbeno enoto, pri čemer je ta gradbena enota lahko glede na vertikalno vrtilno os v celoti zasukijiva in proti ogrodju stroja oz. materialu premakljiva, ne da bi pri tem v kakršnikoli obliki prihajalo do statičnih problemov, ki bi bili odvisni od vsakokratne nastavitve kota poševnega reza. Drugače izraženo nastane s predmetom izuma z vsemi potrebnimi deli opremljen, v nosilcu koles vključen stroj tračne žage, ki se lahko svobodno rokuje glede na ogrodje stroja in s tem vpetje obdelovanca kakor glede na podajanje v smeri materiala obdelovaca kakor tudi glede na pri tem različno nastavljene kote poševnega rezanj a.Due to the elimination of balance shift problems related to the alignment of the inclined wheel carrier bracket, there is now also the possibility of designing a lightweight wheel carrier as a compact unit containing all the necessary components for the saw blade drive resulting from the wheel carrier with a flange attached to the drive train. motor, guides for saw blade diverting, steering and adjusting cutting conditions including the necessary handling tools, etc. In this way, a vertical band saw can be formed essentially like a wheel carrier including a construction unit designed for the operation of the saw, and this unit can be fully rotatable with respect to the vertical rotary axis and against the frame of the machine or machine. the material is movable without causing any static problems in any form, depending on the respective angle of inclination. Otherwise, with the necessary parts of the invention, with all the necessary parts, a band saw machine included in the wheel carrier can be freely operated with respect to the frame of the machine, and thus the workpiece clamping as to the feed in the direction of the workpiece material as well as differently adjusted oblique cutting angles a.
S pomočjo imenovanih, z izumom izvedenih pogojev lahko tudi izvedemo nosilec koles po njegovi konstrukciji lahkega in enostavnega, Kar vključuje prav tako vodenje in vležajsnje nosilca koles proti ogrodju stroja.With the help of the named conditions, the invention can also be used to make the wheel carrier according to its construction light and simple, which also includes guiding and mounting the wheel carrier against the machine frame.
Pri tem je vključeno zlasti tudi lahko in samo majhno silo zahtevajoče rokovanje cz. gibanje nosilca koles, ki zahteva odgovarjajoče razmeroma lanko dimenzionirana sredstva za nastavljanje in vodenje.Particularly light and small force requiring cz handling is included in this. movement of the wheel carrier that requires appropriately sized and adjustable means of adjustment and guidance.
Kot primerno se. je izkazala vertikalna namestitev vrtilne osi. Če gre pri tern vrtilna os skozi mesto reza, tvori praktično črto prodora, ki izhaja iz ravnine rezanja po eni strani in iz na stranice nosilca koles navpične naležne ravnine materiala. To ima prednost, da se zaradi različne nastavitve kota poševnega rezanja mesto rezanja žaginega traku proti materialu obdelovanca ne menja, tako da glede na to ni potrebno upoštevati nobenih korekturnih veličin glede na vzdolžno nastavitev materiala obdelovanca „As appropriate. showed the vertical positioning of the rotary axis. If the rotary axis passes through the cut location, it forms a practical penetration line, which originates from the cutting plane on one side and from the sides of the wheel carrier on the vertical contact plane of the material. This has the advantage that the cutting position of the saw blade does not change with respect to the workpiece material due to the different adjustment of the angle of inclination, so that no correction values are required in relation to the longitudinal adjustment of the workpiece material. '
Za rokovanje vertikalne tračne žage po izumu se lahko p· imika material v smeri reza proti žaginemu traku, kar se lahko realizira na primer s horizontalno gibljivimi sanmi za sprejem materiala obdelovanca. Nato se material primika v smeri rezanja ročno ali tudi. 2 drugače odgovarjajoče vodenim pomikom proti toaku žage.In order to handle the vertical band saw according to the invention, the material can be moved in the direction of the cut against the saw blade, which can be realized, for example, by horizontally moving sleds for receiving workpiece material. Then the material moves in the direction of cutting manually or also. 2 otherwise in accordance with the guided movements toward the saw blade.
Principialno je podana druga možnost v tem, da je pomakljiv nosilec kolesa za podajanje traku žage v smeri proti materialu in s tem v smeri reza s sredstvi podajanja. Ta sam po sebi običajen postopek dopušča stacionarno pričvrstitev materiala, nakar se podaja s pomočjo odgovarjajočih pomikov nosilca koles žagin list v smeri reza skozi material.In principle, an alternative is provided in that the movable wheel carrier for feeding the saw blade is in the direction of the material and thus in the direction of the cut with the means of delivery. This inherently customary procedure permits the stationary attachment of the material, and is then provided by means of the corresponding movements of the wheel carrier of the saw blade in the direction of cutting through the material.
Za oba prej imenovana slučaja lahko predvidimo, da je sprejem za material po potrebi v smeri reza pomična miza stroja z v bistvu horizontalno odlagalno površino, pri čemer tvori mizo stroja ogrodje stroja oz. se izoblikuje na njem.For both of the above-mentioned cases, it can be assumed that the material receptacle is, in the direction of the cut, as required, a movable table of the machine with a substantially horizontal storage surface, forming the machine table the frame of the machine or machine. is formed on it.
Pri tem je lahko miza stroja z nosilcem koles zasučna vrtilna miza in lahko se predvidi, da sovpada zasučna os vrtilne mize z vrtrilno osjo nosilca koles.In this case, the table of the machine with the wheel carrier may be a rotary rotary table and it can be assumed that the rotary axis of the rotary table coincides with the rotary axis of the wheel carrier.
Za sprejem materiala za žaganje je primerno, da je predviden za material za žaganje na strani materiala, obrnjeni k nosilcu koles, in najmanj na eni strani ravnine rezanja traku žage čvrsto stoječ naležni most z v bistvu vertikalno vpenjalno ploskvijo za material. Na ta način se lahko pozicionira material na določen način paralelno k njegovemu vzdolžnemu poteku, da se nato dovaja bodisi z gibanjem sprejema materiala v smeri k žaginemu traku in paralelno k smeri reza proti rezu žaganja bodisi da se dopusti, rezajoče podajanje nosilca koles in s tem žaginega traku v takšni obliki, da je material v določeni poziciji, ki jo vnaprej podaja naležni most.In order to receive the saw material, it is appropriate that it is provided for the saw material on the side of the material facing the wheel carrier and at least on one side of the cutting plane of the saw blade a firmly fixed contact bridge with a substantially vertical clamping surface for the material. In this way, the material can be positioned in a certain way parallel to its longitudinal course, in order to be fed either by movement of the material in the direction of the saw blade and parallel to the incision towards the saw blade, or by allowing the wheel carrier to be cut and thereby the saw blade in such a form that the material is in a predetermined position provided by the bridge.
V smislu poprej rečenega je tu primerno, da je vrtilna os nosilca koles v ravnini vpenjalne ploskve naležnega mostu naprave. S tem je vpenjalna ploskev vertikalna naležna ravnina na material obdelovanca, v kateri leži vrtilna os nosilca koles tako, da ostane neodvisno od vsakokratne nastavitve zasučne lege nosilca koles mesto reza med žaginim trakom in materialom vedno enako in zato ni potrebna nobena korektura, odvisna od nastavljenega kota poševnega reza.In the sense of the foregoing, it is appropriate here that the pivot axis of the wheel carrier is in the plane of the clamping surface of the contact bridge of the device. In this way, the clamping surface is a vertical contact plane to the workpiece material in which the pivot axis of the wheel carrier lies so that, regardless of the respective adjustment of the rotary position of the wheel carrier, the cutting position between the saw blade and the material is always the same and therefore no adjustment is required, depending on the set inclination angle.
Za nadaljnje oblikovanje čvrstega vpetja materiala med postopkom rezanja je prednostno, da je vsaj za material horizontalno nasproti naležnega mostu proti vpenjalni ploskvi naležnega mosta nameščena vpenjalna čeljust, ki steza, se lahko odpre in zapre in ima v bistvu prav tako vertikalno vpenjalno ploskev. S to vpenjalno čeljustjo se lahko stisne material proti vpenjalni ploskvi naležnega mosta.In order to further form a firm engagement of the material during the cutting process, it is preferable that at least for the material horizontally opposite to the contact bridge, a clamping jaw is installed against the suspension bridge, which can be opened, closed, and essentially also has a vertical clamping surface. With this clamping jaw, the material can be compressed against the clamping surface of the suspension bridge.
V tem okviru je vendar lahko tudi vpenjalna ploskev v smeri reza žaginega traku, potekajoča stran od žaginega traku nagnjena proti vertikali. Takšna izvedba omogoča, da se dopusti delovanje klina med materialom in vpenjalno ploskvijo oz. njeno vpenjalno ploskvijo zaradi rezilne sile, ki jo izvaja žagin trak, ki služi dodatno nepremični opori materiala med postopkom rezanja.In this context, however, the clamping surface may also be directed in the direction of the cutting of the saw blade, extending vertically away from the saw blade. Such an arrangement allows the wedge between the material and the clamping surface or the clamping surface to be allowed. its clamping surface due to the cutting force exerted by the saw blade, which serves as an additional fixed support for the material during the cutting process.
Da dopustimo glede vpenjalne čeljusti prečno na ravnino rezanja iz nižje razloženih razlogov dovolj svobode gibanja za žagin trak, je primerno, da izkazuje vpenjalna čeljust na proti žaginemu traku obrnjeni strani po potrebi izmenljiv material za lahek vrez žaginega traku, tako da ne čuti žagin trak za popolno predrtje materiala tudi pri lahnem poševnem položaju žaginega gIn order to allow sufficient freedom of movement for the saw blade transversely to the cutting plane for the saw blade below, it is appropriate for the clamping jaw to exhibit a lightweight incision of the saw blade on the facing side, if necessary, so that it does not feel the saw blade. complete puncture of the material even at the slight sloping position of the saw g

Alternativno k prej rečenemu se lahko predvidi, da je prirejeno naležnemu mostu poleg rezalne ravnine predvidena vsaj ena vpenjalna čeljust, ki steza material vertikalno proti mizi stroja ter se lahko odpira in zapira.Alternatively to the foregoing, it may be provided that at least one clamping jaw is provided beside the cutting bridge in addition to the cutting plane, which clamps the material vertically against the table of the machine and can be opened and closed.
Takšna vertikalna vpenjalna čeljust, ki se lahko kombinira na primer glede na gradbene dele z naležnim.mostom, daje drugo možnost zlasti z ozirom na materiale obdelovanca kompliciranih površin, ki se eventuelno težko zagrabijo s horizontalno vpenjalno čeljustjo.Such a vertical clamping jaw, which can be combined, for example, with respect to the structural members with a bearing bridge, gives an alternative especially with regard to the workpiece materials of complicated surfaces that may be difficult to grip with a horizontal clamping jaw.
Razumljivo se lahko predvidijo pri vertikalni tračni žagi po izum tako horizontalne vpenjalne čeljusti kakor tudi vertikalne vpenjalne čeljusti skupno, da se uporabijo alternativno ali tudi skupno.It is understandable that both the horizontal clamping jaws and the vertical clamping jaws may be provided jointly with the vertical band saw according to the invention, to be used alternatively or jointly.
Nadalje je primerno, da je izoblikovano pod področjem materiala nameščeno vodilo žaginega traku na nosilcu koles čvrsto stoječe in vodilo žaginega traku, nameščeno nad področjem materiala na nosilcu kolesa v smeri žaginega traku nastavljivo in pritrdljivo. Obe vodili traku žage sta zato lahko v smislu zgoraj rečenega sestavni del nosilca koles in dovoljujeta najožjo nastavitev z ozirom na vsakokraten presek obdelovanca oz. presek materiala, tako da se vodi trak žage vedno neposredno poleg materiala in je lahko oodprt proti nastajajoči sili rezanja. Tega ne ovirata niti horizontalna niti vertikalna vpenjalna čeljust.Furthermore, it is appropriate that the saw blade guide on the wheel carrier formed beneath the material area be fixed and the saw blade guide mounted above the material section on the wheel carrier in the direction of the saw blade adjustable and secured. Both saw blade guides can therefore, in the sense of the above, be an integral part of the wheel carrier and allow for the narrowest adjustment with regard to the respective cross-section of the workpiece or the workpiece. cross-section of the material so that the saw blade runs always directly next to the material and can be opened against the emerging cutting force. Neither horizontal nor vertical clamping jaws obstruct this.
Za proizvajanje velikosti podajanja v smeri rezanja med nosilcem kolesa oz. trakom žage na eni strani in materialom na drugi strani je lahko nosilec koles premičen v 'smeri rezanja vzdolž vodila, vrtljivega in pritrdijivega okrog vertikalne vrtilne osi, v bistvu horizontalno potekajoče. S tem je izvedljivo translatorično gibanje nosilca koles v smeri rezanja proti materialu.To produce feed size in the cutting direction between the wheel carrier or the saw blade on one side and the material on the other, the wheel carrier can be moved in the 'cutting direction along the guide, rotatable and fixed around the vertical rotary axis, essentially horizontally running. This translates into a translational movement of the wheel carrier in the direction of cutting towards the material.
Druga možnost obstoji principialno v tem, da je nosilec koles možno zasukati naprej okrog vertikalne vrtilne osi, zasukijive in pritrdljive, v bistvu prečno na smer rezanja, in horizontalno nameščene zvrnljive osi v smeri rezanja.Alternatively, in principle, the wheel carrier can be rotated forward about a vertical rotary axis, rotatable and fixed, substantially transversely to the cutting direction, and horizontally mounted rotary axes in the cutting direction.
Medtem ko je torej v enem primeru nosilec koles gibljiv translatorično v smeri proti materialu in v kolikor se vodi trak žage pri vzdrževanju njegove smeri teka skozi material, je v drugem primeru predvideno za nosilec kolesa zasučno gibanje okrog, pred materialom ležeče ležajne osi nosilca koles, okrog katere se vodi nosilec koles in s tem trak žage pri postopku rezanja skozi material v obliki loka.Thus, while in one case the wheel carrier is movable translationally towards the material, and to the extent that the saw blade is guided in maintaining its direction of flow through the material, in the other case it is provided for the wheel carrier to rotate about in front of the material of the bearing axis of the wheel carrier, around which the wheel carrier is guided, and thus the saw blade in the process of cutting through the arc-shaped material.
Za obe možnosti podajanja se lahko predvidi, da je nameščeno horizontalno vodilo oz. zvrnljiva os na strojnem delu, ki se lahko suče. na ogrodju stroja okrog vertikalne vrtilne osi. Tu je torej predviden na ogrodju stroja strojni del za vležajenje in vodenje nosilca koles, pri čemer je strojni del sam sukljiv okrog vertikalne vrtilne osi po izumu in s tem sozajema preko vodila oz. zvrnljivega vležajenja nosilca koles sam nosilec koles z ozirom na vrtilno nastavitev okrog vertikalne osi.For both feed options, it may be assumed that a horizontal guide is installed. pivotable axle on machine parts that can be twisted. on the machine frame around the vertical rotary axis. Thus, a machine part for mounting and guiding the wheel carrier is provided on the frame of the machine, wherein the machine part itself is twisted around the vertical rotary axis according to the invention and thus co-existing via the guide or. the roller bearing of the wheel carrier itself the wheel carrier with respect to the rotary adjustment about the vertical axis.
Za izoblikovanje strojnega dela so možne različne oblike. V sledečem so navedene nekatere možnosti, ne da bi bil s tem omejen obseg predmeta izuma.There are different shapes for machine design. The following lists some options without limiting the scope of the invention.
Skupno imajo vendar, to, da se lahko takšen strojni del na znan način vležaji vrtljivo na ogrodju stroja, tako da so izpoljnjene visoke zahteve glede na natančnost in brezzračnost.What they have in common, however, is that such a machine part can be rotated in a known manner by rotating on the machine frame, so that high requirements are met with respect to precision and airlessness.
Tako je lahko strojni del že prej omenjena vrtilna miza, s čemer imamo istočasno naleg za žagani material kot sovrteča se enota in s tem v širokih mejah neodvisno od kota poševnega rezanja vedno razpoložljiva enota.Thus, the machine part can be the aforementioned rotary table, thus simultaneously holding the saw blade as a rotating unit and thus, within wide limits, regardless of the angle of inclination, the unit is always available.
Sicer je možno v normalnem primeru, da ima sprejem ogrodja stroja za material takšno odprtino za žagin trak, ki pušča prosto celotno področje podajanja različnih kotov poševnega rezanja. Pri oblikovanju strojnega dela, ki nosi horizontalno vodilo oz. zvrnljivo os nosilca koles, kot vrtilne mize, izkazuje lahko leta izhajajoč iz središča oz. vertikalne vrtilne osi v smeri podajanja žaginega traku izrez za prehod žaginega traku, ker se takšen izrez nato s kotom poševnega rezanja nosilca koles pre.....Otherwise, it is possible, in the normal case, that the material machine frame receptacle has an opening for a saw blade that leaves the entire area of feed of various angles of oblique cutting free. When designing a machine part that bears a horizontal guide or. The pivotable axis of the wheel carrier, as a rotary table, can be shown by years originating from the center or. vertical axis of rotation in the direction of the saw blade feed, a cutout for the saw blade passage, since such a cut is then pre-.....
stavi in s tem omogoča žaginemu traku vedno njegovo svobodno gibanje, po drugi strani pa se s tem zmanjša naleg za material obdelovanca vedno samo za velikost izreza, s čemer se šele omogoči obdelava kratkih kosov materiala.This allows the saw blade to always move freely, which in turn reduces the workpiece material attachment only by the size of the cut, only allowing short pieces of material to be machined.
Da bi omogočili nosilcu koles proti vrtilni mizi potrebno svobodo gibanja, je samo potrebno, da ima vrtilna miza, izhajajoč iz njenega središča vrtenja v smeri proti nosilcu koles v bistvu izpust v obliki četrtine kroga za sprejem nosilca koles in delov, ki so z njim povezani v ravnini vrtilne mize kakor tudi za sprostitev vrtilnega gibanja nosilca koles med obema njegovima zunanjima podajnima položajema. Izpust vrtilne mize je torej prilagojen v ravnini vrtilne mize zunanjemu obrisu nosilca koles vključno z njim povezanih delov, tako, da je nosilec koles kvazi svobodno gibljiv znotraj vrtilne mize, ki pa nosi istočasno horizontalna vodila oz. zvrnljiva vodila nosilca koles, z ozirom na maksimalno gibanje podajanja. Ker se nahaja ta izpust vrtilne mize glede na obdelovanec oz. material vsakokrat v bistvu za čvrsto stoječim priležnim mostom, ne more priti zaradi tega do oviranja podlage oz. podpore obdelovanca na vrtilni mizi.In order to allow the wheel carrier against the pivot table the necessary freedom of movement, it is only necessary that the pivot table, starting from its center of rotation in the direction of the wheel carrier, be essentially discharged in the form of a quarter circle for receiving the wheel carrier and the parts associated therewith in the plane of the rotary table, as well as to release the rotational motion of the wheel carrier between the two outer positions of the wheel. The discharge of the rotary table is therefore adjusted in the plane of the rotary table to the outer contour of the wheel carrier, including its associated parts, so that the wheel carrier is quasi-freely movable within the rotating table, which at the same time bears horizontal guides or. retractable wheel carrier guides with respect to maximum feed movement. Because this discharge of the rotary table is located in relation to the workpiece or the workpiece. in each case, the material is essentially behind a rigid bearing bridge, which cannot result in obstruction of the substrate or surface. workpiece supports on the rotary table.
Kar se tiče vležajenja strojnega dela, ki izkazuje horizontalno vodenje oz. zvrnljivo vodenje nosilca koles, oz. vrtilne mize, je primerno, da je strojni del oz. vrtilna miza vrtljivo vležajen na ogrodju stroja vzdolž svojega oboda. V ta namen se lahko predvidi, da ima strojni del oz. vrtilna miza navzdol se iztezajoči krožnocilindrični nastavek, da ima nastavek na svojem spodnjem koncu znotraj in zunaj horizontalno okrog potekajoči vodilni utor in da so v vprijemu z vodilnim utorom vodilne koluti, ki so vrtljivo vležajene na ogrodju stroja okrog vertikalne osi.As for the mounting of the machine part, which exhibits horizontal guidance or. reversible steering of the wheel carrier, respectively. rotary tables, it is appropriate that the machine part or. rotary table pivotably mounted on the machine frame along its circumference. For this purpose, it may be assumed that the machine part or. pivoting table extending a circular cylindrical attachment so that the attachment has a guide groove at its lower end inside and outside, and that there are guide rolls engaged with the guide groove which are rotatably mounted on the machine frame about a vertical axis.
Tako je zagotovljeno na razmeroma velikem obodu vležajeno vodenje strojnega dela oz. vrtilne mize tako v horizontalni kakor tudi v vertikalni smeri, ki se lahko oblikuje odgovarjajoče varno proti zvrnitvi in stabilno, po drugi strani pa tudi zagotavlja, da ga pri žaganju nastali rezilni material ne umaže oz. ovira.Thus, a relatively large perimeter is provided for the rigid running of the machine part or. rotary tables, both horizontally and vertically, which can be shaped appropriately safe against rolling and stable, and on the other hand ensures that the saw blade does not get dirty or dirty. obstacle.
Druga možnost obstoja v tem, da je strojni del oz. vrtilna miza v področju nog ogrodja stroja vrtljivo vležajen, pri čemer se lahko predvidi, da je strojni del oz. vrtilna miza preko vertikalnih opornih sredstev povezana s horizontalno nožno ploščo, in da je nožna plošča na ogrodju stroja preko radialno - aksialnega ležaja vrtljivo vležajena.Another possibility is that the machine part is. the pivot table in the area of the legs of the machine body is pivotably mounted, and it can be assumed that the machine part or. the pivot table is connected to the horizontal footplate by means of vertical support means, and that the footplate on the machine body is pivotally mounted through the radial - axial bearing.
Za to vrtljivo vežajenje veljajo odgovarjajoče prej omenjene prednosti.This rotating exercise is subject to the aforementioned advantages.
V kolikor gre v prejšnjem za v bistvu horizontalno potekajoče vodenje nosilca koles, se lahko predvidi, da obstoji horizontalno vodenje nosilca koles iz vodilnega droga, ki ga objema korespondirajoči vodilni del nosilca koles, kakor tudi iz poleg nameščene proti zavrnitvi oz. zasuku varujoče izvedbe, v katero vprijema oporna ročica, ki izhaja od vodilnega dela nosilca kolesa in ki je s svojim koncem premakljiva.If the former is essentially horizontal running of the wheel carrier, it may be envisaged that there is a horizontal guide of the wheel carrier from the guide bar, which is enclosed by the corresponding guide section of the wheel carrier, as well as from the anti-roll or anti-roll bar. a rotating protective design which is supported by a support arm which arises from the guide portion of the wheel carrier and which is movable with its end.
S tem oblikovanjem horizontalnega vodenja je ustvarjena posebno enostavna, iz običajnih delov sestavljiva konstrukcija, ki pa po drugi strani jamči najvišjo mero stabilnosti in varovanja nosilca koles proti zavrnitvi iz njegove vertikalne lege.This horizontal guidance design creates a particularly simple, custom-built construction, which, in turn, guarantees the highest degree of stability and protection of the wheel carrier against rejection from its vertical position.
Pri tem lahko izakazuje vodilni drog v bistvu krožni presek, s čemer nastane zlasti ugodna izdelava horizontalnega vodenja.In doing so, the guide bar may be substantially circular in cross-section, resulting in a particularly advantageous horizontal guidance.
Za zasukljivost nosilca koles naprej v smeri reza okrog osi zvrnitve je prednostno, da je ta zvrnitvena os v smeri reza žaginega traku vodena v bistvu horizontalno prestavljivo in premakljivo. S tem lahko dose?emoj da zavzame žagin trak po prerezanju materiala obdelovanca na koncu ločilnega reza vertikalno smer teka, kar se izkaže glede primeroma na horizontalno vpenjalrio čeljust kot posebno ugodno. Pri tem je lahko prestavitev zvrriitvene osi izvesti z nastavnim vretenom, ki je vležajeno na zvrnitver.em delu stroja vrtljivo ali aksialno nepomično.In order to rotate the wheel carrier forward in the cutting direction about the pivot axis, it is advantageous that this pivot axis in the direction of the saw blade is guided essentially horizontally adjustable and movable. In this way, the saw blade can be occupied after cutting the workpiece material at the end of the cutting cutter in the vertical direction of the run, which proves to be particularly advantageous, for example, on the horizontal jaw. In this case, the displacement of the vibration axis can be effected with an adjusting spindle mounted on the inverted part of the machine rotating or axially stationary.
Za obe prej opisani možnosti podajanja žaginega traku v smeri materiala, torej tako za horizontalno podajanje kot tudi za z zvrnitvijo sukajoče podajanje je primerno, da so pritrjena sredstva za podajanje na eni strani na strojni del in po drugi strani na nosilec koles zasučno, pri čemer so lahko sredstva za podajanje na primer hidravlični, ci 1 i ndrično-batni agregat ali nastavno vreteno.For both of the options described above for feeding the saw blade in the material direction, both for horizontal feeding and for tilting the twisting feed, it is appropriate that the feed means attached on one side to the machine part and on the other to the wheel carrier rotate, wherein the means of delivery may be, for example, a hydraulic, ci 1 i n-piston unit or a teaching spindle.
Da nastavimo velikost padajanja za nosilec koles v odvisnosti, od preseka žaganega materiala, je prednostno v primeru horizontalne.....In order to set the fall size for the wheel carrier depending on the cross-section of the saw material, it is preferable in the case of horizontal .....
ga vodenja nosilca koles, da je nameščen paralelno k horizontalnim vodilom na strojnem delu vsaj en nastavek za omejitev gibanja in po potrebi za povratek nosilca kolesa. Pri tem je lahko nastavek nastavljiv s pomočjo na strojnem delu vrtljivo vležajenega nastavnega vretena in z nastavkom lahko delujejo zaustavijalni nosovi, ki so vsaj posredno čvrsto povezani z nosilcem koles.by guiding the wheel carrier so that it is mounted parallel to the horizontal guides on the machine part by at least one attachment to restrict movement and, if necessary, to return the wheel carrier. The nozzle may be adjustable by means of a rotating bearing spindle mounted on the machine part and the nozzle may be actuated by the nozzle, which is at least indirectly firmly connected to the wheel carrier.
Takšna sredstva za nastavljanje zlasti omogočajo, da lahko tako omejimo podajanje traku žage, da se material samo delno nareže, se pravi da se material ne prereže popolnoma, kar je zlasti potrebno za izdelavo izrezov iž materiala, pri čemer se lahko izdelajo takšni izrezi z vertikalno tračno žago po izumu iz različnih nastavitev vrtilnega položaja nosilca koles v kombinaciji z različnimi položaji podajanja materiala obdelovanca v njegovi vzdolžni smeri, pri čemer žagin trak nareže material na dveh različnih mestih pod različnimi koti poševnega reza.Such adjusting means, in particular, allow us to limit the delivery of the saw blade so that the material is only partially cut, that is, the material does not cut completely, which is especially necessary for the production of cutouts from the material, whereby such cutouts can be made vertically a band saw according to the invention from different adjustments of the rotational position of the wheel carrier in combination with different feed positions of the workpiece material in its longitudinal direction, with the saw blade cutting the material at two different positions at different angles of oblique cut.
Žagani materiali obdelovanca imajo najbolj različne preseke. Po drugi strani izhajamo pri vertikalni tračni žagi iz odgovarjajoče vertikalno potekajoče črte rezanja. V paru črta rezanja/rezani presek obdelovanca lahko sledi, da zadene trak žage pri zarezu na veliko površino obdelovanca, zaradi česar pridejo istočasno številni zobje žaginega traku v vprijem z materialom obdelovanca, kar je za čisti zarez principialno problematično, brez ozira na to, pod katerim kotom rezanja zadene žagin trak na obdelovanec.Sawn workpiece materials have very different cross sections. On the other hand, in the case of a vertical band saw, we draw from the corresponding vertically running cutting line. In pairs, the cutting line / cut section of the workpiece can be followed to hit the saw blade with a cut on a large surface of the workpiece, which simultaneously causes many saw blade teeth to adhere to the workpiece material, which in principle is problematic for a clean cut, regardless of which cutting angle hits the saw blade on the workpiece.
Enako nastane pri vertikalni ureditvi reza za rezanje različnih profilov neugodno razmerje med največjo in najmanjšo rezilno dolžino, kar vodi do zmanjšanja dosegljive storilnosti.In the same way, the vertical arrangement of the cutting section for cutting different profiles results in an unfavorable ratio of the maximum to the minimum cutting length, which leads to a decrease in achievable productivity.
Da bi v okviru izuma za horizontalno vodene nosilce koles rešili tudi ta problem, je predvideno po naslednji značilnosti, da je nosilec koles proti svojemu horizontalnemu vodenju zvrnljiv okrog v bistvu horizontalne, prečno na ravnino rezanja ležeče osi in glede na položaj zvrnitve možen fiksiranja. Pri tem je prednostno, da je nameščena zvrnitvena os nosilca koles v področju sredine med obema vertikalnima segmentoma traku žage.In order to solve this problem in the context of the invention for horizontally guided wheel carriers, it is envisaged according to the following feature that the wheel carrier rotates about its horizontal direction about substantially horizontal, transversely to the plane of cutting of the axial axis and, depending on the position of turning, is possible to be fixed. Preferably, the pivot axis of the wheel carrier is positioned in the middle region between the two vertical segments of the saw blade.
S tem je doseženo, da se nosilec koles lahko zvrne glede na obliko preseka žaganega materiala za kot, ki se giblje normalno med 0’ in 3’, za katerega so lahko možni tudi redi velikosti od na primer 5 do 10°, v smeri na obdelovanec, tako da zadene trak žage samo z majhno dolžino vprijema za narez na obdelovancu, s čemer je v vprijemu najprvo samo malo zob traku žage z materialom obdelovanca, kar vodi hitro do dobrega vodenja traku žage v področju nareza in s tem do čistega nareza. S tem povezano spremembo r azmet rezilne dolžine pride pri rezanju profi Irtih materialov do povečanja storilnosti.Thereby, the wheel carrier can be rotated according to the cross-sectional shape of the sawn material for an angle that moves normally between 0 'and 3', for which orders of magnitude from 5 to 10 ° may also be possible, in the direction of the workpiece by striking the saw blade with only a small length of grip for cutting into the workpiece, which initially contains only a small tooth of the saw blade with the workpiece material, which leads quickly to good guidance of the saw blade in the cutting area and thus to a clean cut. The associated change in the cutting length r elation results in productivity gains when cutting profi irt materials.
Za konstrukcijsko oblikovanje te zvrnljivosti nosilca kolesa je prednostno, da je nosilec koles priključen na svojem vodilnem delu, ki sodeluje v vzdolžnem vodenju, zvrnljivo oz. zasučno in da se lahko pričvrsti glede na položaj zvrnitve oz. zasuka. Tu lahko predvidimo, da je predvidena za nastavitev in zaustavitev zvrnitve nosilca koles med nosilcem koles in vodilnim delom vstavljena nastavitvena priprava, ki je lahko na primer oblikovana kot nastavno vreteno.For the structural design of this rotation of the wheel carrier, it is preferable that the wheel carrier is connected to its guide part, which is involved in the longitudinal guidance, in a retractable manner. swivel and that it can be fixed according to the position of the roll or. twist. It can be assumed here that an adjusting device is provided for adjusting and stopping the rotation of the wheel carrier between the wheel carrier and the guide part, which may, for example, be shaped as a teaching spindle.
Prejšnja problematika glede na eventualno zeljeni poševni narez materiala je v bistvu povezana s horizontalno vodenim nosilcem koles. Pri nosilcu koles, ki se lahko zasuče okrog pod materialom obdelovanca ležeče zvrnljive osi v .srneri podajanja oz. v smeri reza, se reši ta problem z nagnjeno lego nareza traku žage proti materialu samem, ki izhaja iz zasučnega gibanja nosilca koles.The previous problem with the possibly desired slanting of the material is essentially related to the horizontally guided wheel carrier. With a wheel carrier that can be rotated around under the workpiece material of the pivoting axle in the feeder or. in the direction of the cut, this problem is solved by tilting the saw blade against the material itself resulting from the rotary movement of the wheel carrier.
Is. dokončno omejitev gibanja podajanja nosilca koles, vseeno, če se izvede to gibanje podajanja s horizontalnim pomikom ali z zasukom okrog osi zvrnitve, se lahko predvidi na ogrodju stroja stikalna ročica, ki sega v področje gibanja enega roba oz. ploskve nosilca koles, katero se lahko nastavi glede na velikost pomika nosilca koles, pogojeno s presekom materiala. Tu gre torej v nasprotju z že preje diskutiranim nastavkom za zaustavljač, čigar nastavitev je odvisna od preseka vsakokratnega obdelovanega materiala in ki skrbi za to, da se nosilec koles po prerezu materiala odklopi in po potrebi premika nazaj.Is. a definitive restriction on the movement of the wheel carrier, however, if this movement is carried out by horizontal movement or by rotation about the axis of rotation, a switch lever extending into the area of movement of one edge or the front may be provided on the machine body. of the wheel carrier surface which can be adjusted according to the size of the wheel carrier displacement, conditioned by the cross-section of the material. This is in contrast to the previously discussed stop adapter, the setting of which depends on the cross-section of the material being machined, and which ensures that the wheel carrier disengages after cutting the material and moves back when necessary.
Pri tem omenjena stikalna ročica je lahko nameščena pod sprejemom za žagani material, v ogrodju stroja, sodelujoča s sprednjim robom oz. sprednjo ploskvijo nosilca koles. Tako je torej primeroma v slučaju prej poudarjene vrtilne mize pod vrtilno mizo nastavljivo nameščena.In doing so, said switch lever may be positioned below the saw material receptacle, in the frame of the machine, cooperating with the leading edge or. the front face of the wheel carrier. Thus, in the case of the previously emphasized pivot table, it is adjustably positioned below the pivot table.
Kot je bilo že prej večkrat omenjeno, je primerna vertikalna tračna žaga po izumu v njeni temeljni sestavi predvsem tudi za izvedbo tako imenovanih prostoročnih rezov, torej takšnih rezilnih delovnih hodov, pri katerih se dovaja material traku žage z roko preko sprejema materiala na ročno krmiljeni način. Za to je zlasti primerno, da se lahko nosilec koles aretira v svojem, glede na smer rezanja skrajno sprednjem položaju podajanja, ker lahko premikamo obdelovanec povsem neovirano od drugih sestavnih delov vertikalne tračne žage na prost način proti traku žage. V tem oziru nudi vertikalna tračna žaga po izumu posebne prednosti, pri Čemer so držani vsi strojno bistveni deli izven območja sprejema materiala, tako da lahko premikamo vsakokratni material obdelovanca prosto proti traku žage.As mentioned above, the vertical band saw according to the invention in its basic structure is particularly suitable for the execution of so-called hands-free cuts, ie such cutting work moves, in which the material of the saw blade is fed by hand through the material receiving in a manually controlled manner . In particular, it is appropriate for the wheel carrier to be locked in its own, depending on the cutting direction at the far front of the feed position, since the workpiece can be moved completely unhindered from other components of the vertical band saw in a free way against the saw blade. In this respect, the vertical band saw according to the invention has the particular advantage of keeping all the essential parts out of the material receiving area so that the workpiece material can be moved freely against the saw blade.
Povzeto je ustvarjena z izumom vertikalna tračna žaga, ki omogoča vse, pri žaganju materiala, zlasti materiala v obliki drogov, nastopajoče delovne hode na enostaven način, ne da bi pri tem nastal kompliciran in drag stroj, ki se težko rokuje in ki bi bil zahteven po gradbenem naporu. Nasprotno dobimo z ukrepi po izumu zelo lahko grajen in v svojem rokovanju odgovarjajoče nekomplicirano prernikan stroj, ki ga je možno enostavno in poceni izdelati, ne da bi morali sklepati kompromise na kakršenkoli način glede rnnogostranske uporabljivosti oz. uporabnosti.In summary, the invention is a vertical band saw, which enables everything when sawing material, especially pole-shaped material, to perform work moves in a simple way, without creating a complicated and expensive, difficult-to-handle and demanding machine. after construction effort. By contrast, the measures according to the invention provide a very easily built and in its handling a suitably uncomplicated machine, which can be easily and inexpensively produced without having to compromise in any way with regard to its versatile usability. usability.

Najprvo bomo pregledali različne poglede vertikalne tračne žage po izumu po sl 1 do 4.First, we will examine the different views of the vertical band saw according to the invention according to Figures 1 to 4.
Tu je razvidno ogrodje l stroja, čigar delovna miza v obliki vrtilne mize 2 dovaja žagani material 3 v obliki palice preko vodilne proge 4, primeroma kotalne proge, in s katerim se odvaja razrezani material preko vodilne proge 5, primeroma kotalne proge.This shows a frame l of a machine whose workbench, in the form of a rotary table 2, supplies a saw-like material 3 in the form of a rod over a guide line 4, for example a rolling line, and by which a cut material is discharged via a guide line 5, for example a rolling line.
Na ogrodju 1 stroja je nameščen vertikalni nosilec 6 koles. Ta kaže zgornje kolo 7 in spodnje kolo 8, okrog katerih teče brez.....A vertical carrier of 6 wheels is mounted on the machine frame 1. This shows the upper wheel 7 and the lower wheel 8, which runs around without .....
končni žagin trak 9. Vrtilne osi 10 koles so nagnjene proti ravnini rezanja 11, razvidne oz. nastavljene s sl. 1 do 4 za kot pod 90°, v tem primeru 45°.end saw blade 9. The rotating axes 10 of the wheels are inclined towards the cutting plane 11, visible or respectively. continued with FIG. 1 to 4 for an angle below 90 °, in this case 45 °.
Za zasuk žaginega traku 9 v ravnino rezanja 11 sluzijo vodila 12 (glej tudi sl. 5 oz. sl.7) in 13, pri tem je nameščeno vodilo 12 pod naležno ravnino obdelovanca 3 na nosilcu 6 koles čvrsto stoječe, medtem ko je vodilo 13 odgovarjajoče smeri puščice 14 na sl. 1 na nasilcu koles vertikalno premično v vodilu 15 in čvrsto pritrdljivo. čvrsta pritrdijivost vodila 13 žaginega traku znotraj vodila 15 ni prikazana podrobno. To je lahko primeroma stezni vijak ali slično. r The guides 12 (see also Fig. 5 or Fig. 7) and 13 are used to rotate the saw blade 9 into the cutting plane 11, with the guide 12 being mounted firmly against the work plane 3 on the wheel carrier 6 while the guide 13 corresponding to the direction of arrow 14 in FIG. 1 on wheel impeller vertically movable in guide 15 and firmly attached. firm attachment of the guide 13 of the saw blade inside the guide 15 is not shown in detail. This may be an example of a clamping screw or the like. r
Za držanje žaginega materiala 3 na vrtilni mizi 2 služi na straneh nosilca 6 koles naležni most 16, čvrsto nameščen na delovni mizi ogrodja 1 stroja, ki obstoji v tem primeru iz dveh odsekov, ki omogočata prehod žaginega traku 9 v smeri materiala 3 obdelovanca s pomočjo zareza 17. Deli naležnega mosta 16 so povezani izven vrtilne mize 2 čvrsto z ogrodjem 1 stroja in omogočajo med temi povezavami prosto gibanje vrtilne mize 2Z zunanjih koncev delov naležnega mosta 16 izhajajo horizontalno prečno na smer podajanja materiala 3 obdelovanca raztegajoči se vodilni drogovi 17’, 18, na katerih se vodi premično vpenjalna čeljust 19, ki steza material 3 obdelovanca proti vertikalni vpenjalni ploskvi 20 naležnega mosta z lastno, prav tako vertikalno vpenjalno ploskvijo 21. Vpenjalna čeljust 19 se lahko pritrdi na vodilnih drogovih 17’ in 18 primeroma s pomočjo roke posluževanih steznih vijakov 22, 23.To hold the saw material 3 on the rotary table 2, a roller bridge 16, firmly mounted on the work table of the machine frame 1, consists in this case of two sections allowing the passage of the saw blade 9 in the direction of the workpiece material 3 by means of the workpiece 6 notch 17. The parts of the drawbridge 16 are connected outside the pivot table 2 firmly to the machine frame 1 and allow, during these connections, the free movement of the pivot table 2With the outer ends of the parts of the drawbridge 16 extend horizontally transversely to the feed direction of the workpiece material 3, the extendable guide bars 17 ', 18 on which a movable clamping jaw 19 is clamped, which clamps the workpiece material 3 against a vertical clamping surface 20 of its own bridge, as well as a vertical clamping surface 21. The clamping jaw 19 may be secured to guide rods 17 'and 18 by means of a hand served clamping screws 22, 23.
Vpenjalna čeljust 19 je lahko opremljena kot je na sl. 2 nakazano, tudi z vepnjalno ploskvijo 21’,' ki je nagnjena potekajoč od zgoraj proti spodaj, v smeri rezanja žaginega traku, potekajoč stran od žaginega traku proti vertikali. Tako se lahko izkoristi delovanje klina, ki ga izvaja žagin trak, med materialom in vpenjalrio čeljustjo v smislu boljšega držanja materiala obdelovanca.The clamping jaw 19 may be provided as in FIG. 2 as indicated, also with the clamping surface 21 ',' inclined from the top to the bottom, in the direction of cutting the saw blade, extending away from the saw blade towards the vertical. Thus, the action of the saw blade wedge between the material and the clamped jaw can be utilized in order to better hold the workpiece material.
Alternativno ali v dopolnitvi k vpenjalni čeljusti 19 se lahko predvidi vertikalna vpenjalna čeljust 55, ki je, kot je nakazano na sl. 2, navpično pomična na držaču 26, pritrjenem na naležnem mostu 16, z nastavnim vretenom 57, pri čemer je nastavno vreteno 57 ročno poslužljivo s prijemnim križem 58. Pri tem se ]!ahko vležnjenje 59 nastavnega vretena izoblikuje zasučno okrog držača 56 ter se lahko spreminja v njegovem horizontalnem položaju, tako da se lahko nastavijo različne razdalje med držačem 56 in nastavnim vretenom 57.Alternatively or in addition to the clamping jaw 19, a vertical clamping jaw 55 may be provided which, as indicated in FIG. 2, vertically movable on the retainer 26 attached to the suspension bridge 16, with the adjusting spindle 57, the adjusting spindle 57 being manually operable with the receiving cross 58. In this case, the sliding drawbar 59 of the adjusting spindle is rotatable around the retainer 56 and can be varies in its horizontal position so that different distances between the holder 56 and the adjusting spindle 57 can be adjusted.
Za izvedbo delovnega hoda žaganja je, kot je najprvo na osnovi sl. 1 nakazano z dvojnimi puščicami, nosilec 6 koles pomičen vzdolž puščice 24 horizontalno v smeri proti žaganemu materialu 3. Da bi omogočili nosilcu koles za to znotraj vrtilne mize 2 potrebno gibalno svobodo, izkazuje vrtilna miza v bistvu četrtkrožne oblike izpust 25, ki odgovarja horizontalni zunanji konturi nosilca 6 koles in skupno z njim povezanim delom v področju ravnine vrtilne mize.To perform the sawing workflow, it is, as a first step, based on FIG. 1 indicated by double arrows, the 6 wheel carrier movable along the arrow 24 horizontally in the direction of the saw material 3. In order to allow the wheel carrier to have the necessary movement freedom within the rotary table 2, the rotary table shows a substantially quarter-shaped discharge 25 corresponding to the horizontal outer the contours of the 6 wheel carrier and the work associated with it in the plane of the plane of the rotary table.
Poleg tega je nosilec koles vzdolž puščice 26 nasproti vertikale zvrnljiv, pri čemer ostane pri takšnem gibanju zvračanja žagin trak 9 znotraj ravnine rezanja s svojim delom, ki leži med vodili 12, 13.In addition, the wheel carrier is reversible along the arrow 26 opposite the vertical, leaving the saw blade 9 within the cutting plane with its part lying between the guides 12, 13 in such a rolling motion.
Končno je vrtilna miza 2 vzdolž puščice 27 vrtljiva oz. zasukljiva, pri čemer napravi nosilec 6 koles skupaj to zasučno gibanje, tako da se lahko nastavi kote poševnega reza proti žaganemu materialu 3. Zasučni položaj vrtilne mize 2 je pri vsakokratnem željenern kotu možno aretirati. Za takšno aretiranje lahko služijo po sebi znana sredstva. Tu je zaradi enostavnosti prikazano ročno posluževanje 28 odgovarjajoče stezne priprave.Finally, the rotary table 2 along the arrow 27 is rotatable or rotatable. rotating, whereby the 6-wheel carrier makes this rotary motion together, so that the angles of inclination can be adjusted against the saw material 3. The rotary position of the rotary table 2 can be arrested at any desired angle. Known remedies can serve for such arrest. Here, for ease of reference, the manual operation of the 28 corresponding track preparation is shown.
Končno je potrebno posebej poudariti, da leži zasučna os 29 vrtilne mize 2 in s tem tudi rezilne ravnine žaginega traku 9 v vpenjalni ploskvi 20 naležnega mosta 16, torej sovpada s črto, vzdolž katere se zažaga material 3 obdelovanca. S tem sledi kraj zažaganja obdelovanca 3 vedno na istem mestu, neodvisno od tega, v katerem zasučnem položaju se nahaja vrtilna miza 2 nosilca 6 koles. S tem se prepreči, da bi morali upoštevati za različne nastavitve vrtilne mize 2 in nosilca 6 koles vsakokrat različna mesta nareza na materialu obdelovanca. To je važno za nastavitev merilnih nastavkov za material obdelovanca,, ker tam v odvisnosti od nastavijenecja kota ni treba izvajati nobene dolžinske korek24 ture.Finally, it should be emphasized that the rotary axis 29 of the rotary table 2 and, consequently, the cutting plane of the saw blade 9 in the clamping surface 20 of the bearing bridge 16, therefore coincide with the line along which the workpiece material 3 is engaging. In this way, the workpiece 3's firing point is always in the same place, regardless of the rotary position of the rotary table 2 of the 6-wheel carrier. This prevents the different cut points on the workpiece material from being taken into account for different settings of the rotary table 2 and the 6 wheel carrier. This is important for adjusting the workpiece material settings, since there is no need to perform any length correction24 tours depending on the angle setting.
Da bi se lahko žagin trak 9 pri rezalnem pomiku znotraj vrtilne mize 2 premikal brez nevarnosti kolizije, izkazuje vrtilna miza 2 izrez 30 za žagin trak, ki se odgovarjajoče prej rečenemu glede na položaj kota vrtilne mize in nosilca kolesa vrti skupaj. Ta izrez skrbi zato. da je naležna površina materiala 3 obdelovanca na vrtilni mizi 2 čim večja.In order to allow the saw blade 9 to move without cutting collision at the cutting movement within the rotary table 2, the rotary table 2 has a cutout 30 for the saw blade, which corresponds to the foregoing with respect to the angle of the rotary table and the wheel carrier rotate together. This cutout is why. that the contact surface of the workpiece material 3 on the rotary table 2 is as large as possible.
Nadaljuje podrobnosti te najprvo principialno obrazložene zgradbe vertikalne tračne žage vključno njenih bistvenih načinov funkcioniranja bodo sedaj pojasnjene na osnovi nadaljnjih slik.Further details of this first, principally explained structure of a vertical band saw including its essential modes of operation will now be explained on the basis of the following figures.
Najprvo naj se posvetimo na osnovi sl. 5 do 8 vležajenju nosilca 6 koles glede gibanja podajanja vzdolž puščice 24 po sl. 1.First, let us turn our attention to Figs. 5 to 8 mounting the 6 wheel carrier with respect to the feed movement along the arrow 24 of FIG. 1.
Kot je razvidno s sl. 5, 7 in 8, je povezan z vrtilno mizo 2 vodilni drog 31 z, v bistvu krožastim presekom preko iz področja naseda obdelovanca navzdol iztezajočega krožnocilindričnega nastavka 32 oz. vertikalnega opornega sredstva 32’. Na vodilnem drogu 31 je nosilec 6 koles s svojim vodilnim delom 33, ki popolnoma objema vodilni drog 31, premakljiv paralelno k ravnini rezanja. Da se ne bi nosilec 6 koles na vodilnem drogu 31 zvrnil, izhaja od vodilnega droga 33 oporna ročica 34, ki oprijema s svojim prostim koncem v vodilo 35 za varovanje vrtenja, ki je nameščena paralelno k vodilnemu drogu 31 na vrtilni mizi 2.As can be seen from FIG. 5, 7 and 8, is connected to the pivot table 2 by a guide bar 31 with a substantially circular cross-section through a workpiece downwardly extending a circular cylindrical attachment 32 or. vertical support means 32 '. On the guide bar 31, the wheel carrier 6 with its guide member 33, which completely encloses the guide rod 31, is moved parallel to the cutting plane. In order to prevent the wheel carrier 6 from rotating on the guide bar 31, a support arm 34 is provided from the guide rod 33, which grips with its free end to a rotation guard 35, which is arranged parallel to the guide rod 31 on the rotary table 2.
Nastanek gibanja podajanja se opravi s cilindrskim-batnim agregatom 36, ki prijemlje zasučno na eni strani na krožasto-cilindričnem nastavku 32 oz. na opornih sredstvih 32’, medtem ko je na drugi strani pritrjen na vodilni drog 33, ki je povezan z nosilcem fe koles.The actuation of the feed movement is accomplished by a cylinder-piston unit 36 which engages rotatably on one side on a circular-cylindrical extension 32 or. on the support means 32 ', while on the other hand it is attached to the guide bar 33 which is connected to the carrier of the bicycle wheels.
Na ta način nastane enostavno in poceni izvedljivo vodenje podajanja za nosilec 6 koles.This makes it easy and inexpensive to operate the feed for the 6-wheel carrier.
Sl. 5 in 7 kažeta istočasno tudi različno vležajenje vrtilne mize 2 in s tem preko, v bistvu vodilnega droga 31 tudi nosilca 6 kolesa.FIG. 5 and 7 show, at the same time, different mounting of the rotary table 2, and thus via the substantially guiding rod 31 also the carrier 6 of the wheel.
Tako je po sl. 5 vrtilna miza 2 opremljena na svojem krožnocilindričnem nastavku 32 glede na njegov spodnji konec z znotraj in zunaj potekajočimi vodilnimi utori 37, 38, v katere vprijemljejo vodilne koluti 39, 40’, ki so vležajene na ogrodju 1 stroja vrtljive okrog vertikalne osi. Kot je iz sl. 9 razvidno, so te vodilne koluti večkratno porazdeljene preko obsega vrtilne mize. Tako nastane vzdolž velikega obsega in s tem na posebno prevrnitveno - varen način stabilno vležajenje za vrtilno mizo 2 po eni strani in za nosilec 6 koles in s tem povezani strojni del po drugi strani.Thus, according to FIG. 5, the rotary table 2 is provided on its circular cylindrical extension 32 with respect to its lower end with internally and externally running guide grooves 37, 38 into which the guide wheels 39, 40 'which are mounted on the frame 1 of the machine rotate about a vertical axis. As in FIG. 9 it can be seen that these guide wheels are multiply distributed over the circumference of the rotary table. In this way, a stable bearing for the rotary table 2 on the one hand and for the support of 6 wheels and the related machine part on the other hand are formed along a large scale and thus in a particularly rollover - safe manner.

Drugo izvedbeno obliko kaže sl. 7. Tam je vrtilna miza 2 opremljena z navzdol štrlečimi opornimi sredstvi 32’, ki so povezani z nožno ploščo 40, ki' je zopet preko radialno-aksialnega ležaja 42 vrtljivo vležajena na ogrodju 1 stroja. Vselej je vrtilna os, kot je bilo že v zvezi s sl. 1 razloženo, iz sl. 7 še enkrat razvidna os 29.Another embodiment illustrates FIG. 7. There, a rotary table 2 is provided with downwardly projecting support means 32 'which are connected to a foot plate 40, which is again pivotally mounted on the machine frame 1 via a radial-axial bearing 42. It is always a rotary axis, as was already the case with FIG. 1 is explained, from FIG. 7 again visible axis 29.
Sl. 5 ir, 7 kažeta poleg tega paralelno k horizontalnim vodilom nosilca 6 koles na vrtilni mizi 2 nameščena nastavna sredstva 42 za omejitev gibanja in po potrebi za obrnitev nosilca 6 koles v smeri podajanja vzdolž vodilnega droga 31. Ta nastavna sredstva, pomična na vodilu 61, so lahko nastavljiva z nastavnim vretenom, vležajenim na vrtilni mizi 2. Z njimi sodelujejo zaustavljalni nosovi 62. ki so povezani, z vodilnim delom 33 in s tem posredno z nosilcem koles. S tem se lahko gibanje podajanja nosilca 6 koles poljubno omeji, tako da se lahko izvajajo poljubno globoki delni rezi na materialu, torej takšni rezi, pri katerih se material samo delno prereže. Če se nato izvede na primer po podajanju materiala 3 pri drugi primerni nastavitvi kota ravnine rezanja 11, nadaljnji takšen delni rez enake globine, se lahko na materialu obdelovanca izdela na ta način izrez v obliki klina.FIG. 5 ir, 7 show in addition to the horizontal guides of the 6-wheel carrier on the rotary table 2, adjusting means 42 are provided to restrict movement and, if necessary, to rotate the 6-wheel carrier in the feed direction along the guide bar 31. These adjusting means, movable on the guide 61, They can be adjusted by means of an adjusting spindle mounted on the rotary table 2. They are actuated by stopping noses 62. which are connected to the guide part 33 and thus indirectly to the wheel carrier. In this way, the feed movement of the 6 wheel carrier can be arbitrarily restricted so that any partial cuts can be made on the material, ie such cuts where the material is only partially cut. If, for example, after the material 3 is fed at another suitable setting of the cutting plane angle 11, a further such partial cut of the same depth, a wedge-shaped cut may be made on the workpiece material.
Na osnovi sl. l do 4 je omenjena nadalje možnost zvrnitvene nastavitve vzdolž smeri puščice 26 z ozirom na nosilec 6 koles.. Da bi to uresničili, kot kaže zlasti sl. 6 v zvezi s sl. 8, je vodilni del 33 prekinjen tako, da je nosilefc 6 koles, na vodilnem, delu pritrjen zvrnljivo oz. zasučno in pritrdijivo glede na zvrnitveni oz. zasučni položaj. V ta namen je po sl. 6 vodilni del 33, s katerim je nosilec 6 koles v vprijemu z vodilnim drogom 31, prekinjen s pomočjo znanega vrtilnega spoja 43, pri čemer jeBased on FIG. 1 to 4, the possibility of rotating along the direction of the arrow 26 with respect to the wheel carrier 6 is further mentioned. 6 with respect to FIG. 8, the guide portion 33 is interrupted so that the carrier 6 wheels are pivotably mounted on the guide member. swivel and fixable with respect to the reversing or. rotary position. To this end, according to FIG. 6, the guide portion 33, by which the carrier 6 of the wheels is engaged with the guide rod 31, is interrupted by a known rotary joint 43, wherein
- 27 nameščena, kot je primeroma razvidno na sl. 2, os 44 vrtilnega spoja v področju sredine med obema vertikalnima segmentoma žaginega traku 9.- 27 is installed as can be seen from FIG. 2, axis 44 of the pivot joint in the middle region between the two vertical segments of the saw blade 9.
Za nastavitev zvrnitvenega položaja nosilca 6 koles proti horizontalnim vodilom služi med deloma na strani nosilca koles vrtilnega spoja 43 nameščeni odsek vodilnega dela 33, na katerem je nato pritrjen ci1indrsko-batni agregat 36, in nosilcem 6 koles nameščena nastavna naprava 45, ki obstoji iz na nosilcu 6 koles pritrjenih vilic z, od nosilca koles naprej štrlečimi viličnimi kraki 46, in dovoljuje nastavitev zvrnitvenega položaja nosilca 6 koles s, primeroma, posluževanjem nastavnega vretena 47, ki prijema z navojem na delu 33 in je na ne podrobneje prikazani način vrtljivo na viličnih krakih, vendar aksialno nepremično vležajen. Z nastavitvijo nastavne priprave 45 je vendar istočasno tudi zvrnitveni p.oložaj znotraj vrtilnega spoja 43 aretiran.To adjust the tilting position of the 6 wheel carrier against the horizontal guides, a section of the guide portion 33 is mounted between the parts on the wheel carrier side of the pivot joint 43, on which a cylinder piston unit 36 is then secured, and an adjustment device 45 consisting of a supports 6 wheels of fixed forks with, from the wheel carrier forward, projecting fork arms 46, and permits adjustment of the pivoting position of the 6 wheels with, for example, operation of the adjusting spindle 47, which receives the thread on part 33 and is rotatable in the fork limb, but axially immobile. By adjusting the adjusting device 45, however, the reversing position within the pivot joint 43 is also arrested.
Glede normalne omejitve podajanja za žagin trak 9 v odvisnosti od vsakokrat obstoječega preseka materiala 3 se vrnimo še enkrat na prikaz na sl. 4. Tam je razvidna s črtano črto stikalna ročica 49, ki je nameščena zasučno vležajena pod vrtilno mizo na ogrodju stroja. Ta stikalna ročica, ki se lahko na primer na znani način ročno pozicionira oz. nastavi in se s steznim vijakom 63 učvrsti, lahko sodeluje z delom nosilca 6 koles tako, da je pri zadetku tega nosilca koles podajanje žaginega traku z delovanjem znanih stikalnih sredstev pretrgano in evenualno obrnjeno.Referring to the normal feed limit for saw blade 9, depending on the existing cross-section of material 3, let us return to the illustration in FIG. 4. There is shown by a dashed line the switch lever 49, which is pivotally mounted under the rotary table on the machine frame. This switch lever, which can be manually or positioned manually, for example. adjustable and secured by the clamping bolt 63, it can engage the portion of the 6 wheel carrier such that when the wheel is hit, the saw blade feed is broken and possibly reversed by the operation of known switching means.
V uvodu opisa je bila omenjena možnost prostoročnega žaganja. V ta namen je možna sprostitev premične vpenjalne čeljusti 19 iz njenih, iz sl. 1 razvidnih vodilnih kladic 50 s pomočjo steznih vijakov 22, 23, tako da se lahko izvede podajanje materiala 3 ročno pri odgovarjajoči sprostitvi steznega spoja vrtilne mize 2 s pomočjo ročice 28 pri obdelovancu, ki leži na vrtilni mizi 2, pri čemer lahko posluževalec ročno z vrtenjem vrtilne mize 2 in s tern tudi vodila 6 traku žage prereže obdelovanec odgovarjajoče plojubnih kontur. Za to prostoročno žaganje ne nudi torej opisani stroj po odstranitvi vpenjalne čeljusti 19 nobenih ovir. Za izvedbo takšnega prostoročnega žaganja se poleg tega nosilec 6 koles zapelje v svoj najsprednejši položaj in se tam pričvrsti, tako da je žagin trak odgovarjajoče prosto dostopen 2. vseh strani.The introduction of the description mentioned the possibility of hands-free sawing. For this purpose, it is possible to release the movable clamping jaw 19 from her, from FIG. 1 of the visible guide pads 50 by means of clamping screws 22, 23, so that the material can be fed 3 manually at the corresponding release of the clamping joint of the rotary table 2 by means of the lever 28 in the workpiece lying on the rotary table 2, whereby the operator can manually by rotating the rotary table 2 and also by the guide 6, the saw blade cuts the workpiece of the corresponding pie contour. Therefore, after the removal of the clamping jaw 19, the described machine does not offer any obstacles for this hands-free saw. In addition, for carrying out such hands-free sawing, the carrier of the 6 wheels is driven into its forward position and secured there so that the saw blade is suitably freely accessible to all sides.
Sl. 9 kaže še enkrat pogled na vertikalno tračno žago po izumu s čim bolj popolnim prikazom tudi strojnih delov, ki so pod delovno ravnino. Iz tega je rezvidno, da se z nosilcem koles povezuje zlasti tudi pogonski motor 51 kot gradbena enota. K nadaljnjim obstoječim, ne prikazanim gradbenim enotam spada poleg vsega tudi stikalna plošča za nastavitev obratovalnih in podajalnih veličin. Na ta način kaže sl. 9 zlasti jasno, kako je izoblikovan nosilec koles skupno z vsemi za obratovanje žaginega traku po.....FIG. 9 shows again a view of a vertical band saw according to the invention with as complete a representation as possible of machine parts below the working plane. It follows from this that the drive motor 51 as a building unit is particularly associated with the wheel carrier. Further existing, not shown building units include, among other things, a switch panel for setting operating and feed sizes. In this way, FIG. 9 In particular, it is clear how the wheel carrier is designed in conjunction with all for the operation of the saw blade .....
trebnih priprav in enot kot kvazi samostojna, na vrtilni mizi in s tem na ogrodju stroja premična žagina enota, ki ni v njeni svobodi gibanja glede vplivanja na obdelovanec podvržena nobenim omejitvam, da se izdela na obdelovancu poljubne poševne reze, delne reze, prostoročno žagane konture itd. S tem se izkazuje vertikalna tračna žaga po izumu kot stroj, ki se lahko prilagodi vsem običajnim, med obratovanjem nastopajočim zahtevam pri vzdrževanju optimalnih, za žaganje materiala obdelovancev veljavnih pogojev.necessary units and units as a quasi stand-alone, on a rotary table and thus on a machine frame a movable saw unit, which is not subject to any restrictions in its freedom of movement with respect to the workpiece, to be made on the workpiece of any oblique cut, partial cut, hands-free contour etc. The vertical band saw according to the invention thus proves to be a machine that can be adapted to all the usual requirements of maintaining the optimum working conditions of the workpiece material during operation.
Na osnovi sl. 10 do 15 so prikazane še enkrat v poenostavljenem pogledu različne možnosti poševnih rezov, pri čemer je vsakokrat izpuščena prestavljiva spenjalna čeljust 19, da bi. nakazali odgovarjajoče možnosti prostoročnega žaganja.Based on FIG. 10 to 15 are shown once again in a simplified view of the various options of oblique cuts, each with a removable clamping jaw 19 omitted in order to. indicated appropriate hands-free sawing options.
Po sl. 10 in 11 je prikazana vertikalna tračna žaga pri začetku rezanja po eni strani in na koncu rezanja glede na maksimalni presek obdelovanca. Pri tem je torej prikazan nosilec 6 koles enkrat v izhodnem položaju in poleg tega v maksimalno možni legi podajanja, pri čemer maksimalno možna lega podajanja na sl. 11 tudi kaže, kako se? prilega zunanja kontura nosilca koles skupaj s pripadajočimi deli v področju vrtilne mize 2 v četrtkrožni izrez 25 vrtilne mize. Sl. 10 in 11 kažeta ravnino reza navpično na vpnjalno ploskev 2 naležnega mosta 16, torej prečno na smer podajanja materiala obdelovanca.According to FIG. 10 and 11 show a vertical band saw at the beginning of the cutting on one side and at the end of the cutting with respect to the maximum cross-section of the workpiece. Thus, the carrier of the 6 wheels is shown once in the starting position and in addition in the maximum possible feed position, with the maximum possible feed position in FIG. 11 also shows how? fits the outer contour of the wheel carrier together with its associated parts in the area of the rotary table 2 into a quarter-notch 25 of the rotary table. FIG. 10 and 11 show the plane of the cut perpendicular to the clamping surface 2 of the bearing bridge 16, ie transversely to the feed direction of the workpiece material.
Proti temu kažeta sl. 12 in 13 zasučni pložaj, v katerem zavzema ravnina rezanja približno kot 45° na imenovano smer podajanja materiala obdelovanca, pri čemer se meri ta kot vzvratno proti smeri podajanja materiala.Against the subject they say fig. 12 and 13 rotate the tool in which the cutting plane occupies about 45 ° to the specified feed direction of the workpiece material, measuring this angle in the reverse direction to the feed direction.
Po drugi strani kažeta sl. 14 in 15 drugi zasučni položaj nosilca 6 kolesa, pri katerem se meri ravnina rezanja žagi noga traku za kot poševnega reza okrog 20° proti, na smer podajanja materiala obdelovanca pravokotni smeri, in sicer tokrat naprej proti smeri podajanja materiala.On the other hand, they say FIG. 14 and 15 a second rotary position of the wheel carrier 6, in which the cutting plane of the saw blade is measured by a slant angle of about 20 ° to the feed direction of the workpiece in a perpendicular direction, this time forward to the feed direction.
Zlasti sl. 12 in 13 jasno ponazarjata sledeče: če je treba izmenjati žagin trak, mora obstojati čim bolj prosta dostopnost in svoboda gibanja glede odvzema zamenjavanega žaginega traku in namestive novega žaginega traku. V ta namen se lahko prav pri nastavitvi stroja po sl. 12 in 13 na najbolj ugoden način s strani vertikalne tračne žage pride k nosilcu koles, ne da bi bila pri tem v posebni meri stali-moteče na poti naležni most 16, vpenjalne čeljusti 19 itd. To velja zlasti tedaj, če je postavljen stroj na tu ne prikazani način s hrbtom, torej z glede na sl. 12 in 13 levo zunanjo stranjo ob neki steni, tako da ne moremo priti k stroju od zadaj. »In particular, FIG. 12 and 13 clearly illustrate the following: if a saw blade is to be replaced, there must be as much accessibility and freedom of movement as possible regarding the removal of the replaced saw blade and the installation of a new saw blade. To this end, it is precisely when setting the machine according to FIG. 12 and 13, in the most advantageous way, by a vertical band saw, it reaches the wheel carrier without being particularly obstructed by the suspension bridge 16, the clamping jaws 19, etc. in the way. This is especially true if the machine is positioned in the manner not shown here with the back, ie with respect to FIG. 12 and 13 left outside along some wall so we can't get to the machine from behind. »
V sledečem so razložene nadaljnje izvedbene oblike predmeta izuma, ki so prikazane poenostavljeno na sl, 16 do 22, pri čemer veljajo tudi za te izvedbene oblike na osnovi sl. 1 do 15 podane obrazložitve in način delovanja.The following are further embodiments of the subject matter of the invention that are shown simplified in FIGS. 16 to 22, and also apply to these embodiments based on FIG. 1 to 15 the explanations and method of operation given.
Medtem ko je pri na sl. 1 do 15 opisani konstrukciji nosilec 6 koles premičen vsakokrat v bistvu horizontalno na strojnem delu v obliki vrtilne mize 2 v smeri proti materialu 3, so možne za to gibanje dodajanja tudi druge principialne možnosti. Eno teh možnosti ponazarja prikaz na sl. 16 in 17.While at FIG. 1 through 15 to the construction described, the 6-wheel carrier, which is movable in each case essentially horizontally on the machine part in the form of a rotary table 2 towards the material 3, is possible to add other principled possibilities for this movement. One of these options is illustrated in FIG. 16 and 17.
Tu je nosilec 6 kolesa s svojim spodnjim koncem s pomočjo gredi 65 zasučno vležajen okrog osi 66, pri čemer se izteza os 66 horizontalne prečno na ravnino rezanja, podano z žaginim trakom 9, Gred 65 sedi do svoji strani v opornih sredstvih 67 v obliki na obeh straneh nosilca 6 koles nameščenih, vertikalnih lic, ki so pritrjene po svoji strani na ne popolnoma prikazani način na vrtilni mizi 2 na njeni spodnji strani.Here, the wheel carrier 6, with its lower end by means of a shaft 65, is rotatably pivoted about an axis 66, extending the axis 66 horizontally transversely to the cutting plane provided by the saw blade 9, the shaft 65 sits to its side in support means 67 in the form of a both sides of the carrier 6 wheels mounted, vertical faces, which are fixed on its side in a not fully shown manner on the rotary table 2 on its underside.
Okrog osi 66 se lahko suče nosilec 6 koles, kot je zlasti razvidno s sl. 17, preko področja preseka žaganega materiala 3, pri čemer izvaja zasučno gibanje cilindrično-batni agregat 67, ki je zasučno pritrjen na eni strani na vrtilni mizi 2 in na drugi strani na nosilcu 6 koles.A support 6 wheels may be rotated about the axis 66, as shown in FIG. 17, through the cross-sectional area of the saw material 3, in which it rotates cylindrical-piston unit 67, which is pivotally mounted on one side on the rotary table 2 and on the other side on the carrier 6 of the wheels.
Kot je razvidno, je tudi v tem slučaju nosilec 6 koles zasukljiv okrog že prej izčrpno opisane osi 29 skupno z zasukijivostjo vrtilne mize 2 na prav tako že prej opisani način.As can be seen, in this case the carrier of the 6 wheels is also rotatable around the previously exhaustively described axis 29 together with the rotatability of the rotary table 2 in the same manner as previously described.
Pri tej izvedbeni obliki obstoji prav tako prednost, da se material 3 obdelovanca nažaga pri zvrnjenem položaju žaginega traku 9, tako da pride pri postopku zažaganja samo malo zob žaginega traku 9 v vprijem z materialom 3.In this embodiment, there is also the advantage that the workpiece material 3 is incinerated at the rotated position of the saw blade 9 so that only a few teeth of the saw blade 9 engage with the material 3 during the firing process.
Vsekakor vodi gradbena oblika po sl. 16 in 17 k temu, da ima na koncu razžaganja žagin trak 9 prav tako zvrnjeni položaj proti materialu 3. tako da mora biti na ne pobliže prikazani način naIn any case, the construction design according to FIG. 16 and 17 to the fact that at the end of the sawing, the saw blade 9 also has a retracted position against the material 3, so that
Da bi te stvari preprečili, so predvideni ukrepi skladno s predelano gradbeno obliko po sl. 18 do 20.In order to prevent these things, the measures envisaged are in accordance with the reconfigured building form of FIG. 18 to 20.
Tu je zopet nosilec 6 koles s svojim spodnjim konccjm na gredi 70 okrog osi 71 zasučno vležajen, pri čemer je gred 70 premična horizontalno preko vodilnih kladic 72, 73 v opornih sredstvih 74, ki so na naprej neprikazani način pritrjena na spodnji strani vrtilne mize 2.Here again bracket 6 bicycles with its lower koncc j m of the shaft 70 about an axis 71 rotatably pivoted, wherein the shaft 70 is movable horizontally over leading blocks 72, 73 in the bracket means 74, which are further not shown manner is attached to the underside of the rotation tables 2.
Os 71 leži zopet prečno na ravnino rezanja, določeno vsakokrat z žaginim trakom 9. Prestavitev kladic 72, 73 se izvede z nastavnimi vreteni 75, 76, ki so na bližje ne predstavljeni način vrtljivo vležajeni in vrtilno poganjani v ogrodju .1 stroja.The axis 71 lies again transversely to the cutting plane determined each time by the saw blade 9. The displacement of the hammers 72, 73 is made by adjusting spindles 75, 76 which are rotatably mounted and rotatably driven in the machine frame.
Kot je iz sl. 19 in 20 razvidno, se lahko nastavijo s pomočjo nastavnih vreten 75, 76 takšne možne točke nosilca 6 koles, da stoji žagin trak 9 na koncu rezalnega delovnega hoda vertikalno.As in FIG. 19 and 20, can be adjusted by means of adjusting spindles 75, 76 such a possible point of the wheel carrier 6 that the saw blade 9 stands vertically at the end of the cutting work stroke.
Tu kaže sl. .19 primer za delni rez, torej takšen postopek rezanja, pri katerem se prereže obdelovanec 3 samo delno. Temu nasproti kaže sl. 20 slučaj, ko žagin list ravno prereže v svojem vertikalnem položaju obdelovanec 3.Here is a fig. .19 case of partial cut, that is, such a cutting process in which workpiece 3 is cut only partially. This is illustrated by FIG. 20 is a case where the saw blade cuts the workpiece 3 in its vertical position.
Tudi za konstrukcijo po sl. 18 do 20 veljajo v ostalem konstrukcijski robni pogoji, ki so bili obrazloženi že pri sl.l do 4 iri ki so nakazani tu še enkrat z uporabo tamkajšnjega oštevičenja.Also for the construction of FIG. 18 to 20 are otherwise subject to structural boundary conditions, which have already been explained in FIGS. 1 to 4, which are indicated here again using the numbering there.
Podajanje nosilca 6 koles se izvaja tudi pri izvedbenem primeru po sl. 18 do 20 zopet s cilindrično-batnim agregatom 77, ki je po eni strani zasučno vležajen na strojnem delu v obliki vrtilne mize 2 in po drugi strani na nosilcu 6 koles.The delivery of the 6 wheel carrier is also carried out in the embodiment of FIG. 18 to 20 again with a cylindrical-piston unit 77, which is pivotally mounted on the machine part in the form of a rotary table 2 and on the other hand on a carrier of 6 wheels.
Medtem ko je bila pri dosedanjih izvedbenih oblikah zasukijivost nosilca 6 koles okrog vertikalne osi 29 prikazana vedno preko strojnega dela, vrtljivo vležajenega na ogrodju 1 stroja, v obliki vrtilne mize 2, so tudi za to različne možnosti. Eno teh možnosti kaže sl. 21. Tam je izoblikovan strojni del kot v bistvu okvir 80 v obliki C, čigar spodnji krak 81 s svojim prostim koncem j e preko vrtilnega ležaja 82 na ogrodju 1 stroja glede na os 29 vrtljivo vležajen.While in the present embodiments, the rotation of the 6 wheel carrier around the vertical axis 29 has always been shown via the machine part rotatably mounted on the machine frame 1 in the form of a rotary table 2, there are also various possibilities for this. One of these possibilities is illustrated in FIG. 21. There is a machine part formed, in essence, a C-shaped frame 80, the lower arm 81 of which with its free end is still pivotably supported by the pivot bearing 82 on the machine frame 1 relative to the axis 29.
Na svojem gornjem, horizontalnem kraku 83 je nosilec 6 koles s pomočjo, na nosilcu 6 koles pritrjene puše 84’ premično izveden, pri čemer je ta pomična priprava'izoblikovana v bistvu tako, kot že na osnovi sl. 5 do 8 izčrpno razloženo., vključno z dodatno zvrni jivostjo nosilca 6 koles okrog osi 44 s pomočjo razdelitve vodilnega dela 33 s pomočjo na njem, okrog osi 44 vrtljivo vležajenega dela 43, pri čemer se lahko izvaja zvrnit-veno gibanje z nastavno pripravo 45 s pomočjo nastavnega vretena 47.On its upper, horizontal arm 83, the carrier 6 of the wheels is movably arranged with the help of the mounting bush 84 fixed on the carrier 6 of the wheels, this movable device being 'substantially shaped in the same way as in FIG. 5 to 8 are exhaustively explained, including the additional reversibility of the 6 wheel carrier about the axis 44 by dividing the guide portion 33 with the help of it, about the axis 44 of the pivotally mounted part 43, whereby a twisted movement can be performed with the teaching device 45 by means of the adjusting spindle 47.
V slučaju sl. 21 se izvaja podajanje nosilca 6 koles s pomočjo cilindrično-batnega agregata 84, ki je na eni strani zasučno priključen na prostem koncu zgornjega kraka 83 okvira 80 oblike C in po drugi strani na nosilcu 6 koles.In the case of FIG. 21, the wheel carrier is fed by means of a cylindrical piston unit 84, which is pivotally coupled on one side to the free end of the upper arm 83 of the C frame 80 and on the other to the 6 wheel carrier.
Izvedbena oblika po sl. 21 tvori razvidno primer, pri. katerem je neprikazani material obdelovanca primeroma oprt samo z vodilno progo 4, 5, kot prikazano na sl. 1, tako da je v področju ogrodja stroje; prost.The embodiment of FIG. 21 forms a striking example at. to which the non-shown workpiece material is substantially supported only by a guide line 4, 5 as shown in FIG. 1, so that it is in the field of the machine frame; prost.
Sl. 2? kaže končno še enkrat v močno poenostavljeni, obliki varianto predmeta po sl 21, ki se razlikuje po tem, da izkazuje zgornji kcal· 83’ okvira 80 oblike C v smeri podajanja nosilca 6 koles oz. žaginega traku 9 navzdol usmerjen nagib, s čemer je podprto delo podajanja v smeri proti obdelovancu s pomočjo določene komponente težnosti. V ostalem veljajo za izvedbeno obliko po sl. 22 obrazložitve k ostalim slikam in zlasti k sl.FIG. 2? shows, once again, in a greatly simplified, object-like variant of FIG. 21, characterized in that it exhibits the upper kcal · 83 'of the C-shaped frame 80 in the direction of delivery of the 6-wheel carrier, respectively. saw blade 9 has a downward tilt, which supports the work of feeding in the direction of the workpiece by means of a specific gravity component. Otherwise, they are considered to be the embodiment of FIG. 22 explanations to the other figures, and in particular to FIG.
..
K vsem na sl. 1 do 22 prikazanim vertikalnim tračnim žagam je potrebno pripomniti, da je v področju naležnega mostu 16, torej v bistvu v področju pred nosilcem koles, pri njegovem nazaj pomaknjenem položaju področja za obdelovani material popolnoma prosto, tu torej niso na poti nobeni strojni deli, kar je zlasti posebnega pomena za večkrat diskutirano prostoročno žaganje. Kar se tiče ogrodja 1 stroja, je le~ta, kar je razvidno zlasti iz sl. 2, za posluževalca ugodno oblikovano, tako da lahko ta posluževalec stopi zelo blizu 12 ogrodja stroja brez težav ter se lahko obrne k obdelovanemu materialu neovirano.To all in Figs. 1 to 22, the vertical band saws shown should be noted that in the area of the bearing bridge 16, ie essentially in the area in front of the wheel carrier, at its backward displaced position of the area for the material being machined, there are no machine parts here, is of particular importance for the many times discussed hands-free sawing. As for the frame 1 of the machine, it is the lens, which can be seen in particular from FIG. 2, conveniently designed for the operator, so that the operator can step very close to the 12 frame of the machine without difficulty and can access the processed material unobstructed.
Na osnovi izvedbenih oblik na sl. 21 in 22 je bilo zlasti opozorjeno. da se tu dela brez vrtilne mize ali drugačnega gradbenega dela, ki bi tvoril strojno mizo. To je Lahko zelo primerno za posebne slučaje, ker tako lahko padajo pri žaganju nastali odrezki in druga umazanija in odpadni kosi neovirano navzdol v ogrodje 1 stroja, kot posebni slučaji uporabe naj bo tu opozorjeno na rezanje dolgih materialnih odsekov, na primer profilov v povezavi z vodenjem materiala na kotalnih progah.Based on the embodiment in FIG. 21 and 22 were particularly noted. to work here without a rotary table or other construction work that would form a machine table. This can be very suitable for special cases, because the saw cuts and other dirt and waste cuts can easily fall down into the frame 1 of the machine, as special cases of use should be noted for cutting long material sections, such as profiles in connection with by running the material on rolling lines.
