Under the pressure of the upper or lower mold of the CNC press brake, the metal plate first undergoes elastic deformation and then enters plastic deformation. In the initial stage of plastic bending, the sheet metal is free to bend. As the upper or lower molds exert pressure on the sheet metal, the sheet metal gradually approaches the inner surface of the V-groove of the lower mold, and the curvature radius and bending force arm gradually decrease. Continue to apply pressure until the stroke ends, making the upper and lower molds completely contact the sheet metal. At this point, completing a V-shaped bend is usually referred to as bending.

Press brake machine is a machine that can bend thin plates, and its structure mainly includes a bracket. Workbench and clamp, the workbench is placed on a bracket, and the workbench is composed of a base and a pressure plate. The base is connected to the clamp through hinges, and the base is composed of a seat shell. The coil and cover plate are placed in the recess of the seat shell, with the top of the recess covering the cover plate. When in use, the wire is energized to the coil, and after being energized, it generates gravity on the pressure plate, thereby achieving the clamping of the thin plate between the pressure plate and the base. Due to electromagnetic clamping, the pressure plate can be made into various workpiece requirements, and the side wall workpiece can be processed, making the operation very simple.

When in use, the wire is energized by the coil, which generates gravity on the pressure plate after being energized, thereby achieving thin plate clamping between the pressure plate and the base. Due to electromagnetic clamping, the pressure plate can be made into various workpiece requirements and can process workpieces with side walls. The press brake can replace the cnc press brake machine mold to meet the needs of various workpieces.
