The bending machine is a device capable of bending thin plates. Its structure mainly consists of a base, a worktable, and a clamping plate. The worktable is placed on the base, and it is composed of a base frame and a pressing plate. The base frame is connected to the clamping plate through a hinge. The base frame is composed of a housing, a coil, and a cover plate. The coil is placed in the depression of the housing, and the top of the depression is covered by the cover plate. When in use, the wire is used to energize the coil, and after energization, it generates a gravitational force on the pressing plate, thereby achieving the clamping of the thin plate between the pressing plate and the base frame. Due to the use of electromagnetic force clamping, the pressing plate can be made to meet various requirements for the workpiece, and it can also process workpieces with side walls. The operation is also very simple.
