Description
7904384-0. delen av övergångsomrádet. . 7904384-0. part of the transition area. .
En sådan trågformig~plâtdetalj kan djuppressas utan mellanglödgning och utan risk för brott eller veckbildning genom att i enlighet med ett sätt enligt uppfinningen det andra press- ningssteget genomföres med användning av motnåll, som anbringas under plåtdetaljen i övergångsområdet för att tillsammans med stämpeln fasthålla åtminstone övergångsområdets sidoområden under pressningsförloppet och endast medge bearbetning av materialet i nämnda sidoomrâden genom-bockning.Such a trough-shaped plate part can be deep-pressed without intermediate annealing and without risk of breakage or creasing by carrying out the second pressing step in accordance with a method according to the invention using a counter needle which is applied under the plate part in the transition area. side areas during the pressing process and only allow processing of the material in said side areas by bending.
Genom att utforma sidokanten i övergångsområdet så skarp som möjligt och utnyttja ett mothåll uppnås en fullständig inlås- ning av materialet, varvid resultatet av pressningen i det andra steget blir en ren förskjutning uppåt av kanterna på tráget.By designing the side edge in the transition area as sharp as possible and utilizing an abutment, a complete locking of the material is achieved, whereby the result of the pressing in the second step is a pure displacement upwards of the edges of the trough.
Uppfinningen beskrivas närmare under hänvisning till på bifogade ritningar visade utföringsexempel, där fig l visar en perspektivvy underifrån av ett konventionellt oljetråg, fig 2 en vy motsvarande fig 1 av ett oljetråg enligt uppfinningen, rig 3 en planvy av tråget i fig_2 och fig Ä-6 en schematisk planvy samt ett längdsnitt och tvärsnitt, illustrerande sättet vid press- ning av tråget enligt uppfinningen. 7 3 I fíg l visas ett konventionellt oljetråg, som har en djupare del l och en grundare del 2. Mellan den djupare delens 1 bakre vägg 3 och den grundare delens 2 botten H och sidoväggar 5 finns ett generellt med 6 betecknat, mjukt rundat övergångsområde.The invention is described in more detail with reference to exemplary embodiments shown in the accompanying drawings, in which Fig. 1 shows a perspective view from below of a conventional oil trough, Fig. 2 a view corresponding to Fig. 1 of an oil trough according to the invention, Fig. 3 a plan view of the trough in Fig. 2 and Figs. a schematic plan view as well as a longitudinal section and cross section, illustrating the method of pressing the trough according to the invention. Fig. 1 shows a conventional oil trough, which has a deeper part 1 and a shallower part 2. Between the rear wall 3 of the deeper part 1 and the bottom H of the deeper part 2 and side walls 5 there is a generally softly rounded transition area denoted by 6. .
Detta område 6 har ungefär samma krökningsradíe i övergången 7 till bottnen 4 som i övergången 8 till sidoväggarna 5.This area 6 has approximately the same radius of curvature in the transition 7 to the bottom 4 as in the transition 8 to the side walls 5.
I fig 2 och 3 visas ett oljetråg enligt uppfinningen.Figures 2 and 3 show an oil trough according to the invention.
Såsom framgår av figurerna skiljer sig detta trâg från tråget i fig l genom att övergångsområdet 6 har en annan form. Här är övergången mellan den grundare delens botten 4 och sidoväggar 5_ utformad med mycket liten radie, så att en relativt skarp kant 9 bildas. Den centrala delen 10 av övergângsområdet 6 har liksom trå- get i fig l en relativt stor radie. Vid sidan om det centrala om- rådet 10 finns plana, kilformiga områden ll, vars övergång 12 till den djupare delens vägg 3 har liten radie, så att en relativt skarp övergång bildas.As can be seen from the figures, this trough differs from the trough in Fig. 1 in that the transition area 6 has a different shape. Here, the transition between the bottom 4 of the shallower part and side walls 5 is formed with a very small radius, so that a relatively sharp edge 9 is formed. The central part 10 of the transition area 6, like the trough in Fig. 1, has a relatively large radius. Next to the central area 10 there are flat, wedge-shaped areas 11, the transition 12 to the wall 3 of the deeper part has a small radius, so that a relatively sharp transition is formed.
Genom att ge tråget den beskdvna formen kan det utan mel- langlödgning djuppressas ur ett plant plátämne på det sätt, som illustreras schematiskt i fig 4-6. I figurerna betecknar 20 stäm- pel, 21 matris, 22 tillhållare och 23 ett mothâll. J c 79øÄsà4-o I en tvâstegs pressningsoperation kan pressningen avi trågets djupare del l ske på konventionellt sätt i ett förstau steg under användning av en stämpel, som motsvaras av den av den punkt-streckade linjen avdelade vänstra delen av stämpeln 20 i fig Ä. I fig 4 illustreras läget hos de ingående delarna omedelbart föme'det andra pressningssteget. Enligt uppfinningen utnyttjas här ett mothåll 23, vilket tillsammans med stämpeln 20 fasthåller materialet i övergångsområdet mellan den djupare och grundare delen. Mothållet är rörligt, så att det kan för- flyttas nedât tillsammans med stämpeln. Härvid belastar mothál- let materialet med en konstant kraft, som kan styras på hydrau- lisk eller pneumatisk väg. Genom mothállets och stämpelns form med relativt skarpa övergångar i trågets kantområden 9, såsom särskilt framgår av fig 6, åstadkommes att materialet i över- gångsomradet under det andra steget endast bearbetas genom bockning, så att resultatet blir en ren förskjutning uppåt av trågets kanter.By giving the trough the desired shape, it can be deep-pressed out of a flat sheet blank without intermediate soldering in the manner schematically illustrated in Figs. 4-6. In the figures, 20 stamps, 21 matrices, 22 tumblers and 23 denote an abutment. In a two-stage pressing operation, the pressing of the deeper part 1 of the trough can take place in a conventional manner in a first step using a stamp corresponding to the left part of the stamp 20 in the line dashed by the dotted line. Fig. 4 illustrates the position of the constituent parts immediately before the second pressing step. According to the invention, an abutment 23 is used here, which together with the stamp 20 holds the material in the transition area between the deeper and shallower part. The abutment is movable so that it can be moved downwards together with the piston. In this case, the abutment loads the material with a constant force, which can be controlled by hydraulic or pneumatic means. Due to the shape of the anvil and the piston with relatively sharp transitions in the edge areas 9 of the trough, as can be seen in particular in Fig. 6, it is achieved that the material in the transition area during the second step is only processed by bending, so that the result is a pure upward displacement of the trough edges.
På senare tid har man börjat utnyttja laminerad plåt i oljetråg för förbränningsmotorer i syfte att åstadkomma tys- tare motorer. Sådan plåt, som kan bestå av tvâ metallplåtar med ett mellanliggande plastskikt, är avsevärt mycket svårare att forma än massiv plåt. Dylika oljetrâg kan utan problem framstäl- las genom tillämpning av sättet enligt uppfinningen.Recently, the use of laminated sheet metal in oil trays for internal combustion engines has begun in order to achieve quieter engines. Such sheet metal, which may consist of two metal sheets with an intermediate plastic layer, is considerably more difficult to form than solid sheet metal. Such oil trays can be produced without problems by applying the method according to the invention.
Avslutningsvis framhâlles att uppgiften att pressningen sker i två steg icke skall tdflas så att pressningen måste ske i två klart skilda steg under utnyttjande av två olika stämplar utan att man inom ramen för uppfinningen även kan tänka sig ett pressningsförfarande vid vilket det första och andra steget ge- nomföres i en följd, dvs utan markerat avbrott, och med en och samma stämpel, varvid mothållet endast anbringas vid det senare skedet av pressförloppet.In conclusion, it is emphasized that the task that the pressing takes place in two steps should not be taken so that the pressing must take place in two clearly different steps using two different stamps without it being possible within the scope of the invention also to imagine a pressing process in which - is carried out in a sequence, ie without marked interruption, and with one and the same stamp, the abutment being applied only at the later stage of the pressing process.
