Abstract:
Multi-stage forming machine comprising a first combined tool block fitted on a body which is a fixed machine body and a second combined tool block fitted on a body which is a press slide which can be moved back and forth relative to said first combined tool block, the first and second combined tool blocks each having individual tool blocks connected to a common supporting structure, the individual tool blocks of the first combined tool block interacting with the individual tool blocks of the second combined tool block, wherein at least one of said combined tool blocks has a clamping lug and the body corresponding to said at least one of said combined tool blocks has a clamping cam, said at least one of said combined tool blocks being suspended on said clamping cam, said clamping lug having a bearing face for said clamping cam and said clamping cam having a bearing face for said clamping lug, wherein at least one of the bearing faces is inclined relative to a vertical direction so that when a vertically downwardly-directed force is exerted on said at least one combined tool block, said clamping lug is bent resiliently outward by said clamping cam so as to produce a clamping force in a horizontal direction.
