Description

Technical Field

[0001] The utility model relates to the technical field of plate shears, in particular to an anti-scratch device for plate shears. Background Art

[0002] Shearing machine is a forging machine mainly used in the metal processing industry. Through the relative movement of the upper blade and the fixed lower blade, shearing force is applied to the metal sheet, so that the sheet is broken and separated according to the required size.

[0003] Publication No. CN 209698153 U discloses an anti-scratch device for a plate shearing machine. By moving the lower blade holder up and down, the device ensures that the bottom end of the plate being sheared will not be scratched by the blade of the shearing fixed knife on the lower blade holder during movement, thereby improving the shearing quality of the plate being sheared and the shearing efficiency.

[0004] The anti-scratch device for the shearing machine drives the lever to rotate through the connecting block when the support rod moves downward, and the lever moves in an arc shape when rotating, so that the lever can only drive the lower tool holder to fine-tune upward. When the material size is thicker and the lower tool holder needs to move downward a large distance, the position distance of the lower tool holder on the device cannot be moved too far, which makes the lower tool holder easily scratch the surface of the material, so it needs to be improved.
