Abstract
1341591 Hydrostatic extruding ALLMANNA SVENSKA ELEKTRISKA AB 25 May 1971 [26 May 1970] 16836/71 Heading B3P A hydrostatic extrusion press of the type of Specification 1,311,038 with a pressure cylinder 2 on a press frame and a billet holder 17 to press a heated billet 27 and a heated die 9 against a cold die support 10 during closing of the cylinder has a spring 35 between the die and die support to separate them until the fluid pressure in the cylinder has built up. The separation thermally insulates the support from the die and billet and reduces the cooling of the die and billet. The spring 35 seats in a groove in the support. It is preferably a cup spring and may have a peripheral rib (36), Fig. 4 (not shown), to hold it in the groove (34).
