Abstract (en)
[origin: EP0938938A2] The machine has punches (38) with guides (36), and guide elements (32) with holders (60) between them. These transmit an axial force between punches and guides, which is larger than the weight of the punches. The holding force of the holders is overcome by the forces active during punching and return movements. The holders are formed by locking elements on punches or guides, which in rest position form a positive connection between punches and guides, and deflect radially during a punching movement.
