Abstract: An apparatus is disclosed for use in a press brake to be actuated between the ram and bed of such an apparatus to cut and form metal workpieces. The ram of the press brake receives a striker bar that engages a force member to coact with a bed member of the attachment to perform cutting and forming operations. The bed member of the attachment is fixed to the bed of the press brake and includes: a rigidly supported shear plate defining at least one recess to supportably receive a length of linear stock, and a yield block yieldably aligned with the rigidly supported shear plate which also defines at least one recess to supportably receive a length of linear stock. The force member is spring mounted above the bed member for separation from the bed member, and includes a movable shear plate defining at least one extension that is complementary to the recess in a rigidly supported shear plate, the two shear plates being supported in offset alignment.
