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.
The space defined between the separated bed and force members of the attachment is closed by a pair of retainer plates fixed at opposed sides of the bed member, each defining at least one of at least one pair of passages aligned with a recess in the bed member to receive lengths of linear stock. As disclosed, passages are defined (along with recesses and extensions) to accommodate lengths of strap stock, rod stock, bar stock and angle. Forming and notching component structures are also provided.
