CNC press brake is a common hydraulic bending machine with a numerical control operating system. It is an upgraded product of ordinary bending machine. Processing conversion can reduce the labor intensity of operators. But the operating skills of operators are higher than ordinary hydraulic bending machines. The most characteristic of the ratio of CNC press brake and hydraulic NC press brake is its CNC operating system. This is an upgrade of ordinary bending machine, which reduces the operator's hydraulic pressure and enhances processing efficiency. However, the operating requirements and skills of CNC bending machines are much higher than hydraulic bending machines, and they are relatively complicated. The CNC bending machine has multi-step programming function, which can realize multi-automatic operation and complete multi-step parts processing at one time. The hydraulic bending machine is energized by a wire to the coil, and after the current is energized, the pressure plate is attracted, thereby clamping the thin plate between the pressure plate and the base. The hydraulic oil pipe bender includes a bracket, a table and a clamping plate. The table is inserted into the bracket. The table is composed of a seat and a pressure plate. The base is connected to the clamping plate by a hinge. The base is composed of a seat shell, a coil and a cover plate. It is inserted into the recess of the seat shell, and the top of the recess is covered with a cover plate. After the gravitation force is generated on the pressure plate, the thin plate is clamped between the pressure plate and the base. Through the use of electromagnetic force clamping, the platen can place a variety of workpiece requirements, and can process workpieces with workpieces.
