The CNC bending machine is an upgraded product of the ordinary hydraulic bending machine, which is equipped with a CNC operating system. It can reduce the labor intensity of operators due to frequent process conversions. However, the operators need to have higher operating skills compared to ordinary hydraulic bending machines.
The most distinctive feature of the CNC bending machine compared to the hydraulic bending machine is its CNC operating system, which upgrades the ordinary bending machine and reduces the labor force of operators while enhancing processing efficiency. However, at the same time, the operation requirements and skills of the CNC bending machine are much higher and relatively more complex compared to the hydraulic bending machine. The CNC bending machine has the function of multi-step programming and can realize multi-automatic operation to complete the one-time processing of multiple workpiece steps. The hydraulic bending machine applies electric current to the coil through wires, generating attractive force on the bending plate, thereby clamping the thin plate between the bending plate and the base. Due to the use of electromagnetic force clamping, the bending plate can be made into various types to meet different requirements of workpieces, and it can also process workpieces with side walls. The hydraulic bending machine includes a frame, a workbench, and a clamping plate.
The workbench is placed on the frame and consists of a base and a bending plate. The base is connected to the clamping plate through a hinge. The base is composed of a seat shell, a coil, and a cover plate. The coil is placed in the recess of the seat shell, and the top of the recess is covered with a cover plate. When in use, the bending plate clamps the thin plate between the bending plate and the base when the coil is energized. Due to the use of electromagnetic force clamping, the bending plate can be made into various types to meet different requirements of workpieces, and it can also process workpieces with side walls.
