Description
Anordning til dannelse av former ved støpning av rør- Device for forming forms by casting pipe-
formede legemer, særlig sylinderforinger for store shaped bodies, especially cylinder liners for large
forbrenningsmotorer. internal combustion engines.
Når man skal stope rorformede legemer, f.eks. sylinderforinger for store forbrenningsmotorer, fremstilles form og kjerne som separate enheter. Dessuten fremstilles formen i to halvdeler i store rammer, såkalte formkasser, hvori man forst murer opp et leie av ildfast teglsten stort sett av form som en halvsylinder. I denne legges der inn en halvsylindrisk tremodell, og formmaterialet rammes inn mellom denne og det murede leie, noe som utgjor et tungvint og tidskrevende arbeide. Kjernen bygges på forskjellige måter opp i en særskilt kjernekasse, som for stopningen oppvarmes, torkes og svertes samt deretter plaseres i formen. Fremstillingen av disse deler skjer med lengdeaksen for rbrlegemet som skal dannes, i horisontalplanet. When stopping tubular bodies, e.g. cylinder liners for large internal combustion engines, the mold and core are manufactured as separate units. In addition, the form is produced in two halves in large frames, so-called form boxes, in which a layer of refractory brick, generally shaped like a half-cylinder, is first built up. In this, a half-cylindrical wooden model is inserted, and the form material is framed between this and the brick bed, which constitutes a cumbersome and time-consuming job. The core is built up in different ways in a special core box, which for the stuffing is heated, dried and blackened and then placed in the mold. The production of these parts takes place with the longitudinal axis of the rib body to be formed, in the horizontal plane.
Da det tar flere dager for formmaterialet å torke ferdig, krever denne metode meget stor plass. Dessuten behbves to formkasser og to halvsylindriske modeller samt en kjernekasse, hvorav den sistnevnte er bundet til kjernen helt til denne er herdnet så den kan loftes ut av kjernekassen. As it takes several days for the mold material to dry completely, this method requires a lot of space. In addition, two mold boxes and two semi-cylindrical models are needed as well as a core box, the latter of which is tied to the core until it has hardened so that it can be lifted out of the core box.
Når delene er torket ferdig, legges kjernen i underformen, og man må deretter fylle underformen med formningsmateriale mot kjernens ene ende så denne, blir fiksert. Deretter pålegges formens ovre halvdel,og man må benytte et mellomlegg, f.eks. av asbestgarn eller lignende, så formenes kanter ikke blir klemt istykker. Det er den sistnevnte arbeidsoperasjon som resulterer i det "skjegg" som danner seg på begge sider av det ferdige gods i en lang stripe i delingsplanet. Dette "skjegg" må meisles bort, da det ellers ville forårsake skader på de"maskiner man senere dreier stopestykket i. When the parts have finished drying, the core is placed in the sub-mould, and the sub-mould must then be filled with molding material towards one end of the core so that it is fixed. The upper half of the form is then applied, and a spacer must be used, e.g. of asbestos yarn or similar, so that the edges of the forms are not pinched to pieces. It is the latter work operation that results in the "beard" that forms on both sides of the finished goods in a long strip in the dividing plane. This "beard" must be chiseled away, as it would otherwise cause damage to the "machines in which the stop piece is later turned".
Den foreliggende oppfinnelse går ut på en anordning til dannelse av former ved stopning av rorformede legemer, hvor man kan arbeide betydelig enklere og raskere, hvor det kreves meget liten gulvflate for tbrkningen av delene,og hvor det ferdige produkt er helt fritt for det hittil karakteristiske "skjegg". The present invention concerns a device for forming shapes by stuffing tube-shaped bodies, where one can work significantly easier and faster, where a very small floor area is required for the use of the parts, and where the finished product is completely free of the hitherto characteristic "beard".
Oppfinnelsen er karakterisert ved en ytre, rorformet formkasse, en sentral utfyllingsspindel, en rorformet modell samt organer til å fiksere de nevnte deler i konsentriske stillinger på en horisontal bunnplate, samtidig som modellen er utformet slik at den kan trekkes ut i vertikal retning etter at formmateriale innfort i rommene mellom modellen og henholdsvis : kassen og spindelen, har satt seg. The invention is characterized by an outer, rudder-shaped mold box, a central filling spindle, a rudder-shaped model as well as means for fixing the aforementioned parts in concentric positions on a horizontal base plate, at the same time that the model is designed so that it can be pulled out in a vertical direction after the mold material inserted into the spaces between the model and, respectively: the case and the spindle, have settled.
På tegningen er oppfinnelsen som eksempel vist anvendt på en form til stopning av sylinderforing til en stor forbrenningsmotor. In the drawing, the invention is shown as an example applied to a mold for stuffing cylinder liners for a large internal combustion engine.
Fig. 1 viser formkasse, modell og spindel for kjernen. Fig. 2 viser form og kjerne parat til stopning. Fig. 1 shows the mold box, model and spindle for the core. Fig. 2 shows the shape and core ready for stuffing.
Såvel form som kjerne skal i henhold til oppfinnelsen fremstilles stående på et horisontalt underlag>og det er da hensiktsmessig According to the invention, both form and core must be produced standing on a horizontal surface>and it is then appropriate
at man bygger opp delene direkte på en ildfast bunn 10 som senere kan utnyttes under stopningen. Under formningen benytter man en rorformet formkasse 11 og en sylindrisk spindel 12 for kjernen. Formkassen festes til underlaget med bolter. Mellom formkasse og spindel plaseres en rbrformet modell 13 som sentreres i forhold til bunnplaten ved hjelp av en forsenkning 14 som er utformet i denne,og hvis bunn dannes av en plate 15 som spindelen 12 hviler på, og som er forsynt med organer 16 til fiksering av denne. De tre komponenter formkasse, modell og spindel that the parts are built up directly on a refractory base 10 which can later be used during the stuffing. During shaping, a rudder-shaped mold box 11 and a cylindrical spindle 12 are used for the core. The mold box is attached to the substrate with bolts. Between the mold box and the spindle is placed a rib-shaped model 13 which is centered in relation to the bottom plate by means of a recess 14 which is formed in this, and whose bottom is formed by a plate 15 on which the spindle 12 rests, and which is provided with organs 16 for fixation of this one. The three components mold box, model and spindle
er således nbyaktig sentrert i forhold til hverandre. Platen 15 er forsynt med et antall lange stifter 17 som forsterker den nedre del are thus closely centered in relation to each other. The plate 15 is provided with a number of long pins 17 which reinforce the lower part
av den ferdige kjerne og holder denne fast til platen. of the finished core and holds this firmly to the plate.
Oppbygningen av form og kjerne skjer på i og for seg kjent måte ved at man lar formraateriale renne ned i mellomrummene mellom kasse og modell og mellom modell og spindel, og i den forbindelse kan materialet innrammes ved hjelp av i og for seg kjente apparater. Eventuelt kan hele enheten plaseres på en skakemaskin så materialet blir sammenpakket på onsket måte. Form og kjerne blir således formet The build-up of the mold and core takes place in a manner known per se by allowing the molding material to flow down into the spaces between the box and model and between the model and spindle, and in this connection the material can be framed using per se known devices. Optionally, the entire unit can be placed on a shaking machine so that the material is packed together in the desired way. Shape and core are thus shaped
på en gang. at a time.
Når formmaterialet har satt seg tilstrekkelig, loftes modellen og likeledes spindelen vertikalt, og man får da en stopeform When the mold material has set sufficiently, the model and likewise the spindle are lifted vertically, and a stop shape is then obtained
av et utseende som vist på fig. 2. of an appearance as shown in fig. 2.
For å muliggjbre uttrekningen må modellen være hovedsakelig sylindrisk. Fortrinnsvis kan den være ganske svakt konisk så den lettere slipper formen resp. kjernen. En sylinderforing har imidlertid partier som avviker fra den rent sylindriske grunnform, og der finnes derfor lose modellstykker, f.eks. 18 for en ovre flens hvor foringen bæres i sylinderrammen, resp. 19 for et midtre, fortykket parti, hvor der senere skal opparbeides spyleporter. Disse modellstykker er utformet som rbrlegemer og delt f.eks. i tre. Under formningen fastholdes de provisorisk til modellen med modellstifter 20. Innan foringen kan trekkes ut, må stiftene fjernes. Modellstykkene l8 og 19 blir sittende i ytterformen og kan fjernes i forbindelse med den inspeksjon som hensiktsmessig foretas innen stopningen skjer. Man kan da lose båndet som holder formkassen til bunnplaten, og lbfte formkassen med ytterformen fra denne. Såvel kjernen som ytterformen blir da tilgjengelige for inspeksjon, så eventuelle mindre feil kan korrigeres, hvoretter modellstykkene tas bort og flatene svertes. To enable the extraction, the model must be mainly cylindrical. Preferably, it can be quite slightly conical so that it more easily releases its shape or core. However, a cylinder liner has parts that deviate from the purely cylindrical basic shape, and there are therefore loose model pieces, e.g. 18 for an upper flange where the liner is carried in the cylinder frame, resp. 19 for a middle, thickened section, where flush ports will later be constructed. These model pieces are designed as rubber bodies and divided e.g. in wood. During shaping, they are provisionally secured to the model with model pins 20. Before the liner can be pulled out, the pins must be removed. The model pieces l8 and 19 remain in the outer form and can be removed in connection with the inspection that is appropriately carried out before the stuffing takes place. You can then loosen the band that holds the mold box to the bottom plate, and lift the mold box with the outer mold from this. Both the core and the outer form are then available for inspection, so any minor errors can be corrected, after which the model pieces are removed and the surfaces blackened.
I visse tilfelle kan man også ta bort delene av modellstykkene l8 og 19 en og en ovenifra uten å flytte form eller kjerne. Sverting skjer deretter ved at et passende utformet munnstykke fores inn i spalten mellom form og kjerne og sprbyter begge disse med sverte-middel samtidig. In certain cases, one can also remove the parts of the model pieces 18 and 19 one by one from above without moving the mold or core. Blackening then takes place by inserting a suitably designed nozzle into the gap between mold and core and spraying both of these with blackening agent at the same time.
Fig. 2 viser hvorledes ytterformen 21 og kjernen 22 står Fig. 2 shows how the outer form 21 and the core 22 stand
som selvstendige enheter på underlaget. Kjernen rager noe opp over toppen av formkassen og er formet slik at den danner stbtte for en as independent units on the substrate. The core protrudes slightly above the top of the mold box and is shaped so that it forms a base for one
. indre ringflens 23 i et lokk 24. Dette inneholder en ringformet renne 25 forsynt med et antall åpninger 26 som er plasert rett over spalten . inner ring flange 23 in a lid 24. This contains an annular chute 25 provided with a number of openings 26 which are placed directly above the slot
mellom form og kjerne, og hvorigjennom det smeltede Jern renner ned i formen for såkalt sprbytestbpning. Ved hjelp av et antall bolter 27 between mold and core, and through which the molten iron flows down into the mold for so-called sparby casting. Using a number of bolts 27
og avstandsstykker 28 er lokket festet til formkassens overdel på en slik måte at der mellom form og lokk dannes en spalte 29 hvorigjennom gasser som dannes under stopningen, kan unnvike. and spacers 28, the lid is attached to the upper part of the mold box in such a way that a gap 29 is formed between the mold and the lid through which gases formed during the stuffing can escape.
Man vet hvor meget det ferdige stbpestykke skal veie,og kan med relativt stor nbyaktighet bestemme den mengde smeltet jern man i hvert enkelt tilfelle behbver, og som skal tappes i rennen 25 og derfra renne ned i.formen. Modellen er ved den her betraktede sylinderforing av en lengde av 23OO mm, 40 - $ 0 mm hbyere enn hva den ferdige foring skal være, noe som gir tilstrekkelig margin ved bestemmelsen av mengden av jernsmelte. You know how much the finished block must weigh, and can determine with relatively great accuracy the amount of molten iron you need in each individual case, which is to be drained into the chute 25 and from there flow down into the mold. The model is, in the case of the cylinder liner considered here, of a length of 2300 mm, 40 - $ 0 mm higher than what the finished liner should be, which gives a sufficient margin when determining the amount of iron melt.
Modifikasjoner av anordningen kan komme på tale innen Modifications to the device can be discussed within
rammen av patentkravene. Som formmateriale kan man anvende natursand med passende bindemiddel. Det mest hensiktsmessige turde være såkalt sementsand. Innstbpningssystemet kan selvsagt også the scope of the patent claims. Natural sand with a suitable binder can be used as form material. The most appropriate would have to be so-called cement sand. The entry system can of course also
varieres på forskjellige kjente måter. are varied in various known ways.
