Description
Anordning ved strengpresse. Device for string press.
Foreliggende oppfinnelse angår en anordning ved strengpresser, hvor et emne plaseres i en beholder eller s. k. container og fra denne presses ut gjennom en matrise ved hjelp av et pressestempel via en mellom denne og emnet plasert trykkfordelende plugg. The present invention relates to a device for string presses, where a workpiece is placed in a container or so-called container and from this is pressed out through a matrix with the aid of a press piston via a pressure-distributing plug placed between it and the workpiece.
Ved tidligere fremgangsmåter for strengpressing har man ikke kunnet unngå oksydstrøk under overflaten av det pressete material eller sentrale konsent-riske oksydinnenslutninger, s. k. bakendefeil, avhengig av materialets flyteforløp i beholderen under strengpressingen, hvilke feil kan ha en vesentlig utstrekning i lengderetningen. Dette er nu funnet å be-ro på den usymmetriske oppstukingen som skjer ved hjelp av den vanlig forekommende sylindriske plugg, som plaseres for-an stempelet under strengpressingen. In previous methods for strand pressing, it has not been possible to avoid oxide layers under the surface of the pressed material or central concentric oxide inclusions, so-called back-end defects, depending on the flow of the material in the container during strand pressing, which defects can have a significant extent in the longitudinal direction. This has now been found to be due to the asymmetric twisting that occurs with the help of the commonly occurring cylindrical plug, which is placed in front of the piston during string pressing.
Én ytterligere . ulempe ved tidligere strengpressingsmetoder viser seg i en kraftig slitasje av beholderens vegger ved det friksjonsinngrep som blir en umiddel-bar følge av kontakten mellom omkrets-flaten av den sylindriske plugg og beholderens vegger. Pluggen har tidligere vært utført av relativt hårdt material og dessuten har det vært nødvendig at pluggen forholdsvis nøyaktig slutter seg til beholderens vegger for å unngå den tendens til kahtring som alltid foreligger og som naturligvis ytterligere øker friksjonen og slitasjen. One more. disadvantage of previous strand pressing methods is manifested in a strong wear of the walls of the container due to the frictional engagement which is an immediate consequence of the contact between the peripheral surface of the cylindrical plug and the walls of the container. The plug has previously been made of relatively hard material and it has also been necessary for the plug to adhere relatively precisely to the walls of the container in order to avoid the tendency to capsize which is always present and which naturally further increases friction and wear.
Disse ulemper elimineres imidlertid ved anordningen i henhold til oppfinnel- However, these disadvantages are eliminated by the device according to the invention
sen som i det vesentlige karakteriseres ved at det i pressestempelets ende er lagret en sfærisk plugg, f. eks. et kuleformet legeme, hvis dimensjon er slik at den glir med liten klaring i beholderens sylindriske rom. which is essentially characterized by the fact that a spherical plug is stored at the end of the press piston, e.g. a spherical body, the dimensions of which are such that it slides with little clearance in the cylindrical space of the container.
Oppfinnelsen skal beskrives nærmere under henvisning til et utførelseseksempel vist skjematisk på vedføyde tegning, og i forbindelse hermed skal angis ytterligere karakteristiske trekk yed oppfinnelsen.. Fig. 1 viser i skjematisk fremstilling et aksialt snitt av en strengpresse med til-hørende emne, plugg og pressestempel be-liggende utenfor strengpressingsbeholde-ren. Fig. 2 viser samme anordning som fig. 1, men med et emne plasert i strengpressens beholder og tilhørende plugg og stempel i begynnende pressingsstilling. Fig. 3 viser samme anordning som fig. 1 og 2 under pågående pressing, hvor emnet delvis er utpresset gjennom streng-, pressens matrise. The invention shall be described in more detail with reference to an exemplary embodiment shown schematically in the attached drawing, and in connection with this further characteristic features of the invention shall be indicated. located outside the string pressing container. Fig. 2 shows the same device as fig. 1, but with a blank placed in the string press's container and associated plug and piston in the initial pressing position. Fig. 3 shows the same device as fig. 1 and 2 during ongoing pressing, where the blank is partially extruded through the string, the matrix of the press.
På tegningen betegner 1 strengpressens beholder eller s. k. container. Med 2 er betegnet strengpressens munnstykke eller matrise, som oppviser en indre konisk vegg 3 og en ytre vegg 4. Med 5 er betegnet matriseåpningen. In the drawing, 1 denotes the string press's container or so-called container. 2 denotes the nozzle or die of the string press, which has an inner conical wall 3 and an outer wall 4. 5 denotes the die opening.
Med 6 er betegnet et emne, som enten kan være kaldt eller oppvarmet, alt etter typen på den strengpressing som skal gjennomføres. Videre er den for oppfinnelsen karakteristiske plugg betegnet med 7. Denne plugg, som har formen av en sfære eller kule, kan hensiktsmessig bestå av et material, eksempelvis stål, som for-trinnsvis har mindre overflatehårdhet enn veggen 8 i beholderen 1 særlig for å unngå slitasje av beholderen. 6 denotes a blank, which can either be cold or heated, depending on the type of strand pressing to be carried out. Furthermore, the plug characteristic of the invention is denoted by 7. This plug, which has the shape of a sphere or ball, can suitably consist of a material, for example steel, which preferably has less surface hardness than the wall 8 in the container 1, in particular to avoid wear of the container.
Som det videre fremgår av fig. 1 er stempelets forreste ende betegnet med 9. Dette stempel har fortrinsvis en viss koni-sitet i ytterenden 10 og i dens endeflate er -utformet en sfærisk lagerflate 11 passende -for lagring av den sfæriske plugg 7. As further appears from fig. 1, the front end of the piston is denoted by 9. This piston preferably has a certain conicity at the outer end 10 and in its end surface a spherical bearing surface 11 is designed suitable for storing the spherical plug 7.
I fig. 2 vises emnet 6 innført i beholde-iren 1. Dette emne forutsettes eksempelvis å være sylindrisk og fyller som det tfremgår av figuren ikke helt ut beholderens tverrsnitt. Den viste stilling av emnet =6 ^representerer stillingen før strengpres-Tsirjgen, hvor den sfæriske pluggen 7, i an-legg mot lagerflaten 11 på stempelet 9, In fig. 2 shows the workpiece 6 introduced into the container 1. This workpiece is assumed to be cylindrical, for example, and as can be seen from the figure does not completely fill the cross section of the container. The shown position of the workpiece =6 ^represents the position before the string press operation, where the spherical plug 7, in contact with the bearing surface 11 of the piston 9,
-tpresses mot den bakre ende av emnet 6. I fig. 3, som viser forholdet under selve strengpressingen, er emnet ved trykket av :pluggen 7 mot dette brakt til i det vesentlige å utfylle hele tvrrsnittet av beholderen 1 samt ligger videre an mot koniske innervegg 3, idet en stang 12 holder på å presses ut gjennom matriseåpningen 5. Som det fremgår av linjen 13 og av den strekete del 14 av selve kulen, holder emnet 6 nå på å utsettes for et overveiende sentralt konsentrert trykk, hvorved en slags etterslepning skjer periferielt på emnet i beholderen. Ved at kulen nesten line-ært tangerer veggen 8 i beholderen 1, kan et jevn tykt, sammenhengende relativt tynt skall av emnet tilveiebringes, hvilket etter pressingen med letthet kan fraskilles ved presserestens fjernelse. Dette er en ekstra fordel som oppnås i motsetning til tidligere forhold, hvor skallet som følge av kant-ringeri av den sylindriske plugg blir brutt istykker og hvor det alltid foreligger risiko for at delér av skallet ved etter-. følgende pressingsoperasj on innarbeides i det ferdige produkt. Utbørsting av beholderen har som følge herav krevet en ekstra arbeidsoperasjon. Ved denne sentrale pressing oppnår man et helt nytt flytefor-løp i motsetning til tidligere med en kraft-fordeling, som er størst innerst i emnet og avtar mot emnets periferi. Dermed unn-gås også de tidligere ulemper med oksyd- -t is pressed against the rear end of the workpiece 6. In fig. 3, which shows the relationship during the strand pressing itself, the workpiece is brought by the pressure of the plug 7 against it to essentially fill the entire cross-section of the container 1 and further rests against the conical inner wall 3, as a rod 12 continues to be pushed out through the die opening 5. As can be seen from the line 13 and from the dashed part 14 of the ball itself, the workpiece 6 is now being subjected to a predominantly centrally concentrated pressure, whereby a kind of lag occurs circumferentially on the workpiece in the container. By the fact that the ball almost linearly touches the wall 8 in the container 1, a uniformly thick, continuous relatively thin shell of the blank can be provided, which can be easily separated after the pressing by removing the press residue. This is an additional advantage that is achieved in contrast to previous conditions, where the shell as a result of edge ringing of the cylindrical plug is broken into pieces and where there is always a risk of parts of the shell breaking off during post-. the following pressing operation is incorporated into the finished product. As a result, brushing out the container has required an additional work operation. With this central pressing, a completely new flow process is achieved in contrast to previously with a force distribution, which is greatest in the inner part of the workpiece and decreases towards the periphery of the workpiece. This also avoids the previous disadvantages of oxide
strøk under overflaten eller sentrale kon-sentriske oksydansamlinger som kommer fra støpestykkets overflate, og tverrsnittet av den utpressede stang 12 eller lignende blir dermed særdeles homogen langs hele stangens lengde, hvorved også tidligere forekommende uregelmessigheter eller s. k. bakendefeil praktisk talt helt elimineres. layers below the surface or central concentric oxide accumulations that come from the surface of the casting, and the cross-section of the extruded rod 12 or the like thus becomes extremely homogeneous along the entire length of the rod, whereby previously occurring irregularities or so-called rear end defects are practically completely eliminated.
Som det fremgår av fig. 3 foreligger det en viss modifikasjon sammenlignet med fig. 1 og 2 idet stempelets forreste ende 10 er forsynt med en ansats 15, mot hvilken det hviler en ring 16, som er bestemt til å tette, mot beholderveggen 8 og delvis styre stempelet. As can be seen from fig. 3 there is a certain modification compared to fig. 1 and 2 in that the piston's front end 10 is provided with a shoulder 15, against which rests a ring 16, which is intended to seal against the container wall 8 and partially control the piston.
Hva anordningen forøvrig angår fås det ved hjelp av den løse kulen 7 og dens lagerflate 11 en automatisk sentrering av pluggen i forhold til emnets bakre ende, hvilket gjør at kulen 7 allerede etter før-ste trykkpåføring presses inn i emnet og automatisk sentrerer dette samtidig som emnet bringes til å utfylle beholderens tverrsnittsflate. As far as the device is concerned, with the help of the loose ball 7 and its bearing surface 11, an automatic centering of the plug in relation to the rear end of the workpiece is achieved, which means that the ball 7 is already pressed into the workpiece after the first application of pressure and automatically centers this at the same time as the blank is brought to fill the cross-sectional area of the container.
