Description

Technical Field

[0001] The utility model relates to the technical field of plate shearing machines, in particular to a shearing angle adjusting device of a numerically controlled plate shearing machine. Background Art

[0002] Shearing machine is a machine that shears plates with one blade moving back and forth relative to another blade. It uses a moving upper blade and a fixed lower blade, and adopts a reasonable blade gap to apply shear force to metal plates of various thicknesses, so that the plates are broken and separated according to the required size. However, various shearing machines on the market still have various problems. The angle of the CNC shearing machine currently used is fixed, which makes it very inconvenient when the angle of the CNC shearing machine needs to be changed. For this reason, we propose a CNC shearing machine that is easy to adjust the shearing angle.

[0003] For example, the patent application with application number CN202020867948.8 includes a base, a body is fixedly arranged at the top of the base, a mounting plate is movably arranged inside the body, support rods are fixedly arranged on both sides of the top of the mounting plate, the support rods are fixedly connected to the bottom of the body through bearings, a mounting groove is provided at the bottom of the body, and a half gear is fixedly arranged on the top of the mounting plate. The utility model loosens the nut on the outside of the threaded rod, and at this time, the first push rod motor is controlled to shorten, and the pull block is moved upward by the first push rod motor. At this time, the bottom end of the block is set to be non-engaged with the block, and the gear can be rotated by pulling the transmission rod, and the mounting plate is rotated through the support rod through the transmission between the gear and the half gear. The angle ruler set on both sides of the body can well observe the rotation angle of the CNC shearing machine, making it more convenient for the CNC shearing machine to shear and adjust the angle.

[0004] However, when the above-mentioned CNC shearing machine adjusts the angle, it is necessary to first loosen the nut on the outside of the threaded rod, control the first push rod motor to shorten and pull the clamping block upward to make the clamping teeth and the clamping block not mesh, pull the transmission rod to make the gear rotate, and the transmission of the gear and the half gear makes the mounting plate rotate through the support rod. After the angle adjustment is completed, control the first push rod motor to extend and make the clamping block move downward to make the clamping teeth and the half gear mesh to prevent the half gear from rotating, and then tighten the nut on the threaded rod. The operation is relatively cumbersome, thereby reducing the angle adjustment efficiency of the CNC shearing machine. It is urgent to design a shearing angle adjustment device for a CNC shearing machine to solve the above problems. Utility Model Content
