Automatic detection hydraulic adjusting device of shear angle of plate shearing machine

Abstract

The invention relates to an improvement of an adjusting device of the switch blade shear angle of a hydraulic plate shearing machine, and discloses an automatic detection hydraulic adjusting device of the shear angle of a plate shearing machine. The automatic detection hydraulic adjusting device is provided with a machine frame, a left oil cylinder, a right oil cylinder, a tool rest and a controller. The left oil cylinder is communicated with an upper cavity oil pipe and the right oil cylinder is communicated with a lower cavity oil pipe. The automatic detection hydraulic adjusting device is characterized in that both the lower cavity oil pipe communicated with the left oil cylinder and the upper cavity oil pipe communicated with the right oil cylinder are communicated with an electro-magnetic valve through a three-way valve, and the input end of the electro-magnetic valve is communicated with an oil conveying adjusting pipe; a travel switch is installed at the position, located on the left side of the tool rest, of the machine frame, a trigger wheel is arranged on the travel switch, a detection switch group is installed at the position, located on the right side of the tool rest, of the machine frame and a plurality of trigger wheels are arranged on the detection switch group. The automatic detection hydraulic adjusting device solves the problem that the shear angle is prone to being changed and plate shearing quality is poor due to the fact that in the existing adjusting device of the shear angle of the hydraulic plate shearing machine, leakage occurs in a hydraulic oil system, and mainly serves as the improvement of the existing adjusting device of the shear angle of the plate shearing machine.

Description

technical field [0001] The invention relates to an improvement of a shearing angle adjustment device of a hydraulic shearing machine, and is a hydraulic adjustment device for automatically detecting the shearing angle of a shearing machine. Background technique [0002] When the hydraulic shearing machine cuts plates with different thicknesses, the shearing knife needs to adjust the shearing angle of different angles. The adjustment of the shearing angle of the hydraulic shearing machine in the prior art is mainly through the adjustment of the shearing angle on the knife holder. The control of the stroke of the piston rod of the left and right oil cylinders can reach the appropriate shearing angle of the adjustment knife; the problem existing in the shearing angle adjustment device of the hydraulic shearing machine in the prior art is that the hydraulic oil system of the left and right hydraulic oil cylinders of the knife rest has problems. Leakage, the stroke of the piston ...
