Description

Technical Field

[0001] The utility model relates to the technical field of hardware processing, in particular to a hardware plate bending device. Background Art

[0002] Traditional hardware refers to five metals: gold, silver, copper, iron, and tin. After processing, they can be made into works of art or metal devices such as knives and swords. Hardware in modern society is more extensive, such as hardware tools, hardware parts, daily hardware, construction hardware, and safety and fire protection, etc., which are made into plates through a series of processing. However, before making these things, the plates need to be processed, and the main thing is to bend them to make the required objects.

[0003] Currently, commonly used bending devices rely solely on simple extrusion to achieve bending. This can cause the bending position to shift during the bending process, affecting the bending quality. Furthermore, the bending position of the metal sheet cannot be adjusted, making it difficult to perform accurate bending work as needed. Therefore, we propose a metal sheet bending device to solve this problem. Utility Model Content
