Abstract

This clamping mechanism is used in a press brake in conjunction with other tools, such as punches, shears, notchers and the like. The clamping mechanism comprises plunger 1 adapted to be actuated by the ram of the press brake. Plunger 1 abuts pivoted member 2. The latter translates the vertical movement of plunger 1 into a horizontal movement for actuating horizontally slidable wedge 3. This in turn actuates pivoted member 4 which carries rocker jaw member 5. Stationary jaw member 6 cooperates with jaw 5 to position and hold rectangular tubing workpiece 7. Thus workpiece 7 can be acted upon by the other tools associated with the clamping mechanism. Return springs 8 abut stationary members 9 and are for the purpose of returning wedge 3, member 2 and plunger 1 to their normal positions as the press brake jam ascends.

Clamping Mechanism

This clamping mechanism is used in a press brake in conjunction with other tools, such as punches, shears, notchers and the like. The clamping mechanism comprises plunger 1 adapted to be actuated by the ram of the press brake. Plunger 1 abuts pivoted member 2. The latter translates the vertical movement of plunger 1 into a horizontal movement for actuating horizontally slidable wedge
3. This in turn actuates pivoted member 4 which carries rocker jaw member 5. Stationary jaw member 6 cooperates with jaw 5 to position and hold rectangular tubing workpiece 7. Thus workpiece 7 can be acted upon by the other tools associated with the clamping mechanism. Return springs 8 abut stationary members 9 and are for the purpose of returning wedge 3, member 2 and plunger 1 to their normal positions as the press brake jam ascends. During such ascension, jaw 4 pivots away from workpiece 7, due to gravity, so that the latter can be withdrawn.
