Document Type and Number:
Japanese Patent JPH0615385
Kind Code:
A
Abstract:
PURPOSE: To provide a device capable of supporting slabs without being restrained by a machining depth.
CONSTITUTION: A slab 1 is supported during the punching processes and in general operations of plastic deformation. This device is equipped with plural jacks 6. The jacks 6 are placed under the slab 1 in a position corresponding to at least a substantial portion of the surface of the slab during all the operations being carried out on the slab.
