Description
i 142167in 142167
Opfindelsen angår et apparat af den i krav 1 * s indledende del angivne art.The invention relates to an apparatus of the kind specified in the preamble of claim 1 *.
F.eks. fra USA patentskrift 3 620 115 kendes et sådant apparat. I dette kendte apparat bærer et antal kæder 5 hver et antal separate værktøjsbærere, der hver over en kort retliniet arbejdsstrækning bringes i indgreb med en smal zone af bølgerøret og herunder udstanser et hul under samtidig fremføring af bølgerøret. Skal der imidlertid med et sådant apparat sikres en effektiv gennemhulning af det 10 bøjelige bølgerør, en nøjagtig anbringelse af hullerne og en sikker fremføring af bølgerøret under apparatets arbejde, er det nødvendigt, at apparatet arbejder med forholdsvis lav hastighed, således at det har en forholdsvis ringe kapac itet.Eg. from United States Patent 3,620,115 such apparatus is known. In this known apparatus, a plurality of chains 5 each carry a number of separate tool carriers, each of which is engaged over a short rectilinear stretch of operation by a narrow zone of the corrugated pipe and including a cutout while concurrently advancing the corrugated pipe. However, if such an apparatus is to ensure an effective piercing of the flexible corrugated pipe, an accurate placement of the holes and a safe feeding of the corrugated pipe during the operation of the apparatus, it is necessary that the apparatus operate at a relatively low speed so that it has a relatively low velocity. low capacity.
15 Formålet med opfindelsen er at angive et apparat af den nævnte art, der sikrer et fejlfrit arbejde og muliggør en stor arbejdshastighed.The object of the invention is to provide an apparatus of the aforementioned kind which ensures a flawless work and enables a high speed of operation.
Ifølge opfindelsen er dette opnået ved den i krav 1 * s kendetegnende del angivne udformning. Som følge af at de 20 sammenhørende værktøjsbærere tilsammen danner en forholdsvis stiv klup, som helt omslutter bølgerøret, afstives dette således i radial-retningen, at huludstansningen bliver perfekt og som følge af inderfortandingen med nøjagtig rigtig placering af hullerne. Denne inderfortanding og det 25 intime indgreb mellem klup og bølgerør medfører yderligere, at dette fremføres yderst nøjagtigt med samme hastighed som kæderne, og denne sikre styring medfører, at apparatet kan arbejde med stor arbejdshastighed og dermed stor kapacitet, uden fare for unøjagtigheder i forbindelse med huludstans-30 ningen.According to the invention this is achieved by the design of the characterizing part of claim 1 *. As the 20 associated tool carriers together form a relatively rigid club which completely encloses the corrugated pipe, this is stiffened in the radial direction so that the hole punching becomes perfect and as a result of the internal toothing with precisely correct placement of the holes. This inner toothing and the 25 intimate engagement between the club and corrugated pipe further imply that it is conveyed extremely accurately at the same speed as the chains, and this safe control means that the apparatus can operate at high working speed and thus high capacity, without the risk of inaccuracies in connection with hole punch.
Særligt fordelagtigt kan det ifølge opfindelsen være, såfremt udformningen desuden er som angivet i krav 2, der sikrer, at samtlige i indgreb med røret værende klupper udgør en stiv enhed, som bevirker en skånsom behandling af 35 bølgerøret og en jævn fordeling af trækkræfterne i dette over en længere strækning, så at faren for forstrækning af bølgerøret udelukkes.It can be particularly advantageous according to the invention if the configuration is furthermore as stated in claim 2, which ensures that all clutches in engagement with the pipe constitute a rigid unit which causes a gentle treatment of the corrugated pipe and an even distribution of the pulling forces therein. over a longer stretch, so as to exclude the danger of stretching the corrugated pipe.
2 1421672 142167
Desuden kan ifølge opfindelsen udformningen være som angivet i krav 3, således at to sammenhørende værktøjsbærere, når de danner en klup, danner en fuldstændig stiv enhed, der udelukker fejlpåvirkning på bølgerøret.In addition, according to the invention, the design may be as claimed in claim 3, such that when two tool carriers, when forming a club, form a completely rigid unit which excludes faulting on the corrugated pipe.
5 I og for sig er der ikke noget i vejen for, at et ap parat ifølge opfindelsen som de tidligere kendte apparater kan have et større antal kæder, men dog har det vist sig mest hensigtsmæssigt, at udformningen ifølge opfindelsen endvidere er som angivet i krav k, hvilket giver det færreste 10 antal enkeltdele og dermed den simpleste udformning, uden at dette på nogen måde går ud over arbejdets effektivitet og apparatets kapacitet.In itself, there is nothing in the way that an apparatus according to the invention can have a larger number of chains, as in the prior art, but it has been found most convenient that the configuration according to the invention is furthermore as stated in the claims. k, which gives the fewest number of individual parts and thus the simplest design without in any way exceeding the efficiency of the work and the capacity of the apparatus.
Endvidere kan ifølge opfindelsen udformningen være som angivet i krav 5, hvilket også fremmer den skånsomme 15 behandling af bølgerøret samtidig med, at den muliggør, at stanseværktøjerne i hver række kan drives successivt ved hjælp af fælles drivorganer, hvilket yderligere fremmer muligheden for en stor arbejdshastighed. I nævnte tilfælde kan udformningen ifølge opfindelsen endvidere være som 20 angivet i krav 6, så at der sikres en jævn fordeling af de udstansede huller mellem rørets bølgedale.Furthermore, according to the invention, the configuration can be as claimed in claim 5, which also promotes the gentle treatment of the corrugated pipe while allowing the punching tools in each row to be successively driven by common drive means, further promoting the possibility of a large operating speed. . In the said case, the configuration according to the invention can furthermore be as defined in claim 6, so as to ensure an even distribution of the punched holes between the wave valves of the pipe.
. Endelig kan ifølge opfindelsen udformningen være som angivet i krav 7, hvorved det med simple midler er muligt at sikre korrekt drivning af stanseværktøjerne selv med 25 meget stor arbejdshastighed af apparatet.. Finally, according to the invention, the design can be as claimed in claim 7, whereby it is possible with simple means to ensure correct operation of the punching tools even at very high operating speed of the apparatus.
Opfindelsen vil i det følgende blive nærmere beskrevet under henvisning til tegningen, på hvilken fig. 1 viser skematisk og set fra siden en udførelsesform for et apparat ifølge opfindelsen, 30 fig· 2 i større målestok to sammenhørende værktøjs bærere i det i fig. 1 viste apparat i stansestilling, set fra enden delvis i snit, og fig. 3 den ene halvdel af den i fig. 2 øverst viste værktøjsbærer, set fra oven delvis i snit.The invention will now be described in more detail with reference to the drawing, in which 1 is a diagrammatic side view of one embodiment of an apparatus according to the invention; FIG. 2 is an enlarged view of two associated tool carriers in the embodiment of FIG. 1 is a partial cross-sectional view of the apparatus shown in FIG. 3 shows one half of the one shown in FIG. 2 tool carrier shown at top, partly in section, in section.
35 På tegningen er kun vist ds dele af apparatet, som er karakteristiske for den foreliggende opfindelse, og disse dele er kun vist i den udstrækning, som er nødvendig til forståelse af opfindelsen.35 The drawings show only those parts of the apparatus which are characteristic of the present invention, and these parts are shown only to the extent necessary for understanding the invention.
3 142167 I den på tegningen viste udførelsesform for apparatet ifølge opfindelsen er to omløbende endeløse kæder 16, som indbyrdes er vinkelforsatte 180°, således styrede, at de har mod hinanden vendende retliniede arbejdsstrækninger be-5 liggende på hver sin side af bevægelsesbanen for et bølgerør 2 med bølgedale å. Hver kæde 16 bærer et antal værktøjsbærere 1 og således, at hver værktøjsbærer 1 på den ene kæde hører sammen med en værktøjsbærer 1 på den anden kæde og sammen med denne på kæderne l6’s arbejdsstrækning danner 10 en klup 1,1, som helt omslutter bølgerøret 2, idet de to sammenhørende værktøjsbærere eller klup-halvdele på denne strækning ligger tæt op mod hinanden.In the embodiment of the apparatus according to the invention shown in the drawing, two circular endless chains 16, mutually angular 180 °, are so controlled as to have opposite rectilinear working stretches 5 on each side of the path of a wave tube. 2 with wave valleys to. Each chain 16 carries a plurality of tool carriers 1 and so that each tool carrier 1 on one chain is associated with a tool carrier 1 on the other chain and together with this on the working stretch of the chains 16, forms a club 1,1 which completely encloses the corrugated pipe 2 , in that the two associated tool carriers or club halves on this stretch are close to each other.
Hver arbejdsbærer 1 har en indvendig fortanding 3 svarende til bølgerøret 2's bølger og bestemt til på arbejds-15 strækningen at være i indgreb med bølgerøret 2's bølger U, se snitcirklen A i fig. 2, således at bølgerøret 2 sikkert fremføres ved hjælp af apparatet.Each working carrier 1 has an internal tooth 3 corresponding to the waves of the corrugated pipe 2 and intended to engage on the working section 15 with the corrugations U of the corrugated pipe 2, see section circle A in FIG. 2 so that the wave tube 2 is safely conveyed by means of the apparatus.
Værktøjsbærerne 1 er således anbragt på kæderne 16, at de på arbejdsstrækningen sig befindende, hver af to ar-20 bejdsbærere 1 bestående klupper tilsammen danner en bølgerøret 2 omsluttende uafbrudt streng omfattende et antal side om side anbragte klupper.The tool carriers 1 are positioned on the chains 16 such that, on the working line, each of two working carriers 1 consists of bumps together forming a wave tube 2 enclosing uninterrupted string comprising a plurality of bumps placed side by side.
Som det fremgår af fig. 2, har hver værktøjsbærer 1 mindst et mod den tilhørende værktøjsbærer 1 på den anden 25 kæde vendende koblingselement, en koblingstap 21 eller en koblingsbøsning 22, og således, at hvert koblingselement, f.eks. 21, på en værktøjsbærer 1 på arbejdsstrækn ingen er i indgreb med et tilhørende koblingselement, f.eks. 22, på den tilhørende værktøjsbærer 1 på den anden kæde, så at 30 sammenhørende værktøjsbærere på arbejdsstrækn ingen er nøjagtigt styrede og fast sammenholdte i forhold til hinanden.As shown in FIG. 2, each tool carrier 1 has at least one coupling element facing the tool carrier 1 on the other 25 chain, a coupling pin 21 or a coupling sleeve 22, and so that each coupling element, e.g. 21, on a tool carrier 1 on the working line, no one engages with an associated coupling element, e.g. 22, on the associated tool carrier 1 on the other chain, so that 30 related tool carriers on the working line are none accurately controlled and firmly fixed relative to each other.
I hver værktøjsbærer 1 er der forskydelige i styr 13 lejret et antal stanseværktøjer 5 på en sådan måde, at de på arbejdsstrækningen er forskydelige på det nærmeste 35 radialt i forhold til bølgerøret 2's længdeakse. Hvert stanseværktøj 5 bærer ved sin inderende et stanseskær T, 142167 k som er bestemt til slagagtigt at gennembryde bølgedalsvæg-gene i bølgerøret 2 og derved at udstanse huller i disse vægge.In each tool carrier 1, a plurality of punching tools 5 are slidably mounted in guide 13 in such a way that they are displaceable on the working stretch almost 35 radially relative to the longitudinal axis of the wave tube 2. Each punching tool 5 carries at its end a punching cutter T, 142167 k which is intended to impactfully pierce the wave valley walls in the wave tube 2, thereby punching holes in these walls.
I den viste udførelsesform har hver værktøjsbærer 1 5 tre rækker stanseværktøjer 5 således anbragte, at der i hver af to sammenhørende værktøjsbærere 1 bestående klup forefindes seks med samme indbyrdes vinkelafstand på 60° beliggende rækker stanseværktøjer 5· I overensstemmelse hermed er hver af to værktøjsbærere sammensat klup udvendigt seks-10 kantet. Kluppen tjener som følge af fortandingerne 3 som en medbringer-klup for bølgerøret 2. For simpelheds skyld er i fig. 2 kun vist to stanseværktøjer 5·In the illustrated embodiment, each tool carrier 1 5 has three rows of punching tools 5 arranged so that in each of two associated tool carriers 1, there are six rows of punching tools 5 located at the same angular distance of 60 °. Accordingly, each of two tool carriers is composed club exterior six-10 edged. As a result of the toothings 3, the bell serves as a carrier club for the wave tube 2. For simplicity, FIG. 2 only two punching tools shown 5 ·
Hver værktøjsbærer 1 strækker sig på arbejdsstrækningen over et antal, f.eks. ti, bølgedale U i det medbragte bølge-15 rør 2, og hver værktøjsrække har fem stanseværktøjer 5 til gennemhulning af, f.eks. hver anden, bølgedal 4. Fortrinsvis bør stanseværktøjerne 5 i hver to på hinanden følgende rækker være indbyrdes forsatte med en bølgedeling t, se fig. 2 cirkelsnittet B.Each tool carrier 1 extends on the working stretch over a number, e.g. 10, wave valves U in the included wave-15 tube 2, and each tool row has five punching tools 5 for piercing, e.g. each other, wave valley 4. Preferably, the punching tools 5 in each two successive rows should be mutually offset by a wave division t, see FIG. 2 the circle section B.
20 De i styrene 13 styrede stanseværktøjer 5 er påvir kede af tilbageføringsfjedre 10, der er i indgreb med en tværstang il·, som er ført gennem en boring eller slids i stanseværktøjet 5- I den viste udførelsesform er denne tværstang 1^ udformet som en fjederstang, der er anbragt i 25 en slids 15 i værktøjsbærerne 1 og hviler mod tilbageføringsfjedrene 10. Slidserne 15 er udad lukkede ved hjælp af dæksler 18.20 The punching tools 5 controlled in the guides 13 are affected by return springs 10 which are engaged by a cross bar 1, which is passed through a bore or slot in the punching tool 5- In the embodiment shown, this cross bar 1 is designed as a spring rod. , which is arranged in a slot 15 in the tool carriers 1 and rests against the return springs 10. The slots 15 are closed outwards by means of covers 18.
Til inddrivning af skæreværktøjerne 5 er der i stationære holdere 17 anbragt kurvebaner i form af frit dreje-30 lige ruller 9, med hvilke kurvebanefølgere 8, der i den viste udførelsesform udgøres af stanseværktøjerne 5's gennem tilhørende huller i dækslerne 18 udragende ydre frie ender, kommer i indgreb under den tilhørende værktøjsbærer 1 's bevægelse langs arbejdsstrækningen .In order to drive the cutting tools 5, curve paths are arranged in stationary holders 17 in the form of freely rotatable rollers 9, with which curve path followers 8, which in the illustrated embodiment, constitute the outer free ends protruding through associated holes 5 in the covers 18 in engagement during the movement of the associated tool carrier 1 along the line of work.
35 Den hastighed, hvormed stanseværktøjerne drives ind under deres arbejdsslag, afhænger af diameteren af de rulleformede kurvebaner 9. Er denne diameter lille, foregar 5 142167 inddrivningen hurtigere end, hvis den er stor. Da stanse-arbejdet imidlertid udføres på kæderne 16 * s retliniede ar-bejdsstrækninger, kan der selv ved anvendelse af store kur-vebanediametre opnås høje inddrivningshastigheder ved an-5 vendelse af tilsvarende store fremføringshastigheder. En kurvebanerulle 9 med stor diameter kan i så fald påvirke flere, f.eks. tre eller fem, stanseværktøjer 5 på samme tid.35 The speed at which the punching tools are driven during their working stroke depends on the diameter of the roll-shaped waveguides 9. If this diameter is small, the retraction is faster than if it is large. However, since the punching is done on the straight lines of the chains 16 *, even with the use of large curve path diameters, high drive speeds can be achieved by using similarly large feed rates. In this case, a large diameter curb web roller 9 can affect several, e.g. three or five, punching tools 5 at the same time.
Værktøjsbærerne 1 er fast forbundet med kæderne 16 ved hjælp af kædeforbindelsesled 2h, som er optaget i slid-10 ser 19 i værktøjsbærerne 1 og fastgjorte ved hjælp af bolte 25 i tilhørende udboringer 20.The tool carriers 1 are firmly connected to the chains 16 by means of chain connecting links 2h, which are received in wear 19 in the tool carriers 1 and fastened by bolts 25 in associated bores 20.
Værktøjsbærerne 1's fortanding 3 er udformet med udsparinger 23 til sikring af et gnidningsfrit indgreb med bølgerøret 2's bølger.The tooth 3 of the tool carriers 1 is formed with recesses 23 to ensure a smooth engagement with the waves of the wave tube 2.
