Description

Technical Field

[0001] The utility model relates to the technical field of bending machines, in particular to a lower die fixing device for bending machines. Background Art

[0002] A bending machine is a machine that can bend thin plates. It works by cooperating with the tool of the upper mold and the lower mold. When working, the tool will exert great pressure on the lower mold. After a long period of use, the lower mold will deform and the V-groove will expand, which will cause the bent steel plate angle to be inconsistent with the preset angle, affecting the bending quality of the steel plate. The lower mold needs to be replaced, which increases costs.

[0003] After searching, it was found that Chinese patent publication number CN214814213U discloses a lower die fixing device for a steel plate bending machine. A truncated cone-shaped wedge-shaped column is set at the lower end of the lower die. The wedge-shaped column cooperates with a liftable lower die seat, and horizontal fine-tuning devices are set at both ends of the lower die. By changing the tightness of the connection between the wedge-shaped column and the lower die seat, deformation of the wedge-shaped column and the lower die is avoided, and the V-groove of the lower die is avoided from becoming larger, which affects the bending angle of the steel plate.

[0004] However, the above patent has certain deficiencies in actual use. Although the deformation of the wedge-shaped column and the lower mold can be avoided by changing the tightness of the connection between the wedge-shaped column and the lower mold seat, during the downward pressing process of the lower mold, the spring seat will be stretched and deformed to a certain extent, thereby affecting the use of the lower mold. At the same time, after one of the spring seats is deformed to a certain extent, the wedge-shaped column will rub against the workbench, which will further damage the lower mold.

[0005] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content
