Working principle of bending machine:
The hydraulic bending machine comprises a bracket, a workbench and a splint, wherein the workbench is arranged on the bracket; The workbench consists of a base and a pressure plate; The base is connected with the splint through a hinge; The base consists of a seat shell, a coil and a cover plate; The coil is arranged in the groove of the seat shell; And the top of the groove is covered with a cover plate.
When in use, the coil is electrified through the wire, and after electrification, attractive force is generated on the pressure plate, thereby clamping the thin plate between the pressure plate and the base. Due to the electromagnetic force clamping, the pressure plate can be made into various workpiece requirements, and the workpiece with side wall can be processed. Bending machine can meet the needs of various workpieces by changing the die of bending machine.
