Abstract

The invention relates to improvement for upper die clamping devices of bending machines, in particular to an upper die clamp-type hydraulic clamping device of a bending machine. The upper die clamp-type hydraulic clamping device of the bending machine comprises a driving sliding block and a plunger hydraulic oil cylinder. The upper die clamp-type hydraulic clamping device of the bending machine is characterized in that the plunger hydraulic oil cylinder is arranged in a mounting hole in a mounting plate of the driving sliding block, a press plate is arranged on one side, located on a cylinder body of the plunger hydraulic oil cylinder, of the mounting plate, a clamping plate is arranged on the other side, located on a piston rod of the plunger hydraulic oil cylinder, of the mounting plate through ball screws, a clamping groove is formed in the lower portion of the clamping plate, and a tensioning mechanism is arranged in the clamping groove of the clamping plate. The upper die clamp-type hydraulic clamping device of the bending machine solves the problems that the upper die clamping device of the existing bending machine is low in die change operation efficiency, the labor intensity of operation personnel is large, upper die locating accuracy is poor, and the service life of a hydraulic oil cylinder is short. The upper die clamp-type hydraulic clamping device of the bending machine is mainly used for the improvement of the upper die clamping devices of the existing bending machines.

Description

technical field [0001] The invention relates to an improvement of an upper die clamping device of a hydraulic bending machine, which is a clamp-type hydraulic clamping device for an upper die of a bending machine. Background technique [0002] The hydraulic bending machine driving slider is equipped with an upper mold clamping device, which is used to clamp the bending upper mold; the prior art hydraulic bending machine upper mold clamping device mainly includes a pressure plate clamping structure and a hydraulic clamping clamp. Clamping structure, the clamping structure of the clamping plate is to use the clamping force between the fastening screw on the splint and the driving slider to realize the clamping of the upper die, and the clamping structure of the hydraulic clamping is to use the head of the piston rod of the hydraulic cylinder and the The clamping force between the driving sliders realizes the clamping of the upper die; the problems existing in the clamping devi...
