Press brake is a kind of machine that can bend the thin plate. The structure of the press brake mainly comprises a bracket, table and the clamping plate, the worktable is arranged on the supporting table, which comprises a base and a pressing plate, a hinge is connected with the clamping plate through the base by a shell, a coil and a cover plate. When the wire is used, the coil is electrified by the conducting wire, and the pressure plate is generated by the electric power, so that the clamping between the clamp plate and the base plate is realized.
Due to the adoption of the electromagnetic force clamping, the pressure plate can be made into various work pieces, and the workpiece can be processed on the side wall, and the operation is very simple and convenient.
