Title: Method and press for extruding metal billet
Inventor: BETSUSE GII
IPC: B21C27/04
Filed: 1994-05-06
Abstract: PURPOSE: To provide an extrusion process for metal billets which eliminates the waste of time and enhances productivity and an extrusion press. CONSTITUTION: The bottom of a container 3 having a cylindrical housing 4 is closed by a supporting piece 13 and a die 14 is housed in the supporting piece and is supported at a stationary cross piece 1. The billet 6 is put into the cylindrical housing 4 and a dummy block 5 of the same cross section as the cross section of the cylindrical housing is penetrated into the cylindrical housing by a piston 52 of a main cylinder 53 disposed at another stationary cross piece 11, by which the billet 6 is subjected to pre-compression between the dummy block and the supporting piece 13. During this pre-compression, the pressing of the container to the supporting piece is prevented, by which a slight spacing (e) is maintained between the supporting piece and the corresponding end of the container.  As a result, the air in the housing is gradually expelled until the billet 6 is completely added to the wall of the housing 4 during the pre-compression. The extrusion of the billet 6 in the absent state of the air is thus made possible.
