technical field

The utility model relates to the technical field of bending processing, in particular to a bending machine.

Background technique

The bending machine is a machine capable of bending thin plates. Its structure mainly includes a bracket, a workbench and a clamping plate. The workbench is placed on the bracket. The workbench is composed of a base and a pressure plate. The base is composed of a seat shell, a coil and a cover plate, the coil is placed in the depression of the seat shell, and the top of the depression is covered with a cover plate. When in use, the wire is energized to the coil, and after energization, an attractive force is generated on the pressure plate, so as to realize the clamping of the thin plate between the pressure plate and the base. Due to the use of electromagnetic force clamping, the pressure plate can be made into a variety of workpiece requirements, and the workpiece with side walls can be processed, and the operation is also very simple.

The existing bending machine generally needs to use the shearing machine to cut the whole plate into the required size before the bending operation. Although this can meet the production requirements, but in the process of mass production, it is necessary to switch back and forth, stop production, transport, etc. The waste caused is also huge, which is undoubtedly not conducive to the development of modern enterprises. Therefore, a new type of bending machine is needed for blanking, cutting and bending.
