Abstract

A machine for processing metal in sheet or plate form, especially for bending metal sheets. The machine comprises a frame with a table base on the frame and a ram which is vertically displaceable in relation to the table base. The ram has an upper tool, while a lower tool is disposed on the table base, these two tools cooperating to process the metal therebetween. The lower tool is elastically supported on the table base by means of a plurality of individual resilient supports which are arranged in a row on the table base. A plurality of intermediate parts are inserted between the table base and the supports and said parts are displaceable groupwise out of the effective region of selected supports into a neutral position, so that only the supports lying directly under the metal sheet workpiece to be processed are effective.

Dependent claims

A machine for processing metal in sheet or plate form, especially for bending metal sheets, comprising:

a machine frame,
a table base on said frame,
a ram vertically displaceable in relation to said table base,
an upper tool mounted on said ram,
a lower tool disposed on said table base,
said upper and said lower tools cooperating for processing said metal sheet therebetween,
elastically-resilient supporting means for supporting said lower tool on said table base,
said supporting means consisting of a plurality of individual, resilient supports arranged in a row or series on said table base,
a plurality of intermediate parts inserted between said table base and said plurality of individual supports, said intermediate part being displaceable out of the effective region of selected supports in groups and into a neutral position in which said selected supports are ineffective, and
an actuating member for the common displacement of said groups of intermediate parts into said ineffective neutral position.
