摘要

A punching and nibbling press with a rotatable turret comprised by an upper and a lower horizontal plate vertically spaced apart, and each formed with housings which in the upper plate receive punch members and in the lower plate receive die members corresponding with the punch members. Each set of housings is arranged in a ring shaped array about the axis of rotation of the turret. The housings are of large, medium and small relative sizes so that large, medium and small punch members can be fitted in the respective housings in the upper plate, and large, medium and small die members in the housings in the lower plate. When at least one of the large punch members is not required and additional small punch members are needed, a large punch member is removed from its housing and is replaced by an intermediate member formed with two small housings to receive two small punch members. Likewise, the corresponding large die member is removed from its housing and is replaced by another intermediate member formed with two small housings to receive two small die members.
