Abstract (en)

[origin: EP0770437A1] The tool has a guide bush (12), which accepts a stamping die which can extend downwards in the direction of stamping. It also supports a reinforcement plate (16), which can be fixed in the engagement region of the die, using retaining links (34,36) which are fixed to the bush. The plate can be removed axially from the die after the links are released. The retaining links are mounted on the guide bush so that they can be moved, between a position in which the plate is locked in place, and a position in which it is released.
