Description

Technical Field

[0001] The utility model relates to the field of bending machines, in particular to a bending machine which can be positioned quickly. Background Art

[0002] A bending machine is a mechanical device used to process metal sheets. It can bend flat materials into parts at a certain angle. The bending machine is mainly composed of a bracket, a workbench, a clamping plate and other components. The bending machine is widely used in modern manufacturing, especially in the fields of automobiles, electronics, aviation, construction and machinery manufacturing. It can process various metal materials, such as aluminum, steel, copper, etc., and can customize molds according to needs to process parts of various shapes. The bending machine is an important metal processing equipment. Its high precision and stability make it play an important role in various manufacturing fields.

[0003] However, general bending machines do not have the function of metal plate positioning, so workers are often required to place the metal plates on the bending machine for bending. The metal plates need to be manually positioned by workers during the bending process, which wastes a lot of time and reduces the bending efficiency of the metal plates. For this reason, we propose a bending machine that can be quickly positioned. Utility Model Content
