ABSTRACT:
Punches having attachment heels of different types are mounted on a bending press by means of an adapter consisting of a bar or a series of bar segments secured to the top die-shoe of the press. The bottom portion of the adapter body is provided in one vertical face with a recess of greater depth than any type of punch attachment heel. A bearing spacer having the same height as the adapter body recess is placed against the punch heel either at the bottom of the recess or in an external position. The spacer and heel of the corresponding punch are held in position by a cramp which is tightly applied against the adapter body on the same side as the recess opening.
