Hydraulic toothless bending mechanism

Abstract

The invention discloses a hydraulic tooth-free bending mechanism. The hydraulic tooth-free bending mechanism comprises a bending body, a connecting rod device and a hydraulic cylinder, the hydraulic cylinder comprises a piston rod; the piston rod is connected with one end of the connecting rod device; the bending body comprises a revolving shaft; the other end of the connecting rod device is connected with the revolving shaft; the inner side of the connecting rod device is provided with a chamfer; the axial lead of the piston rod is positioned on the outer side of the axial lead of the connecting rod device. The piston rod of the hydraulic cylinder is used for pushing the connecting rod device and driving the revolving shaft of the bending body to rotate, so that pushing of the connecting rod and rotation of the revolving shaft are realized by controlling the hydraulic pressure of the hydraulic cylinder. The hydraulic tooth-free bending mechanism disclosed by the invention has the characteristics of simple structure, high bending efficiency and low manufacturing cost, prolonged service life, and enhanced working reliability.

Description

technical field [0001] The invention belongs to a wire material processing device, in particular to a hydraulic toothless bending mechanism. Background technique [0002] The bending mechanism usually refers to a mechanism that bends within 360°, and has a wide range of applications. Usually, a reduction mechanism is used to drive the shaft to rotate, and the bending of the material to be bent is realized through the rotational motion of the rack and pinion. The structure is complex and the manufacturing cost is high; and the rack and pinion The transmission is prone to breakage of the teeth during meshing, which affects the service life. At the same time, due to the complexity of its structure and the large overall volume, the structure is limited in some places and it is not easy to realize. Contents of the invention [0003] The purpose of the present invention is to provide a hydraulic toothless bending mechanism, which can solve at least one of the above technical pr...
