Title:
DIE EXCHANGING ASSEMBLED BODY FOR EXTRUSION PRESS
Document Type and Number:
Japanese Patent JPS56139221
Kind Code:
A
Abstract:
A metal extrusion press having a die change assembly comprises a platen 12 through which material is extruded, a die holder 18 on a support arrangement of the platen, a transfer station 70 and a frame assembly, preferably comprising two slide blocks 34, 52 movable on the support arrangement and hydraulic motors both having their cylinders supported by one of the slide blocks. The motors move the assembly along the support arrangements to transfer a die holder to the transfer station (having sheared an extrusion from the die) at which a new holder is attached to the assembly for return to the extrusion position. Preferably there are two motors, one operating between the platen and one block, moving both blocks, and the second between the two blocks. The press is compact and die changing is facilitated as compared with die changing on known presses.
