Title: Easier deep-drawing of stainless steels - better-deep-drawing ratios obtd. by heating die and cooling punch
Inventor: WEND EIKE-FRITZ DR ING
IPC: B21D37/16
Filed: 1973-06-25
Abstract: An improved deep-drawing process, esp. for austenitic stainless steels, where the blank is heated to below the recrystallisation temp. in the region which will form the shape, but is cooled in the region where the force is applied. A temp. of 60-200 degrees C. is pref. used for the heated portion of the blank, and -5 to +6 degrees C. used for the cooled portion. The heating can be achieved by inserting heating coils in the die and the sheet-holder, while cooling is effected by the use of coolant channels in the punch. With this process, deeper draws can be obtd. before cracking of the stainless steel sheet occurs.
