Description

Technical Field

[0001] The utility model relates to the technical field of bending machines, in particular to a bending machine capable of preventing wear. Background Art

[0002] A bending machine is a machine that can bend thin plates. Its structure mainly includes a bracket, a workbench and a clamping plate. The workbench is placed on the bracket. The workbench consists of a base and a pressure plate. The base is connected to the clamping plate through a hinge. The base consists of a base shell, a coil and a cover plate. The coil is placed in the depression of the base shell, and the top of the depression is covered with a cover plate. When in use, the coil is energized by a wire, and after energization, an attractive force is generated on the pressure plate, thereby clamping the thin plate between the pressure plate and the base. Due to the use of electromagnetic clamping, the pressure plate can be made into a variety of workpiece requirements, and can process workpieces with side walls. It is also very easy to operate. When the bending machine is working, a layer of cloth needs to be covered and fixed on the lower die to prevent damage to the product surface when the upper and lower dies cooperate. The existing cloth replacement is often replaced by multiple people, and there are many inconveniences when fixing, which affects the work efficiency. Utility Model Content
