The CNC bending machine adds a CNC operating system to the ordinary hydraulic bending machine, and is an upgraded product of the ordinary bending machine. Frequent process conversion can reduce the labor intensity of the operators, but the operating skills of the operators are higher than that of ordinary hydraulic bending machines.
The hydraulic press bending machine is mainly composed of left and right columns, worktables, and beams to form a frame. The left and right oil cylinders are fixed on the upright column, and the sliding block is connected with the piston of the oil cylinder and moves up and down along the guide rail fixed on the upright column. The lower mold is fixed on the worktable, and the upper mold is installed at the lower end of the slider. The hydraulic system provides power, and the electrical system gives instructions. Under the action of the oil cylinder, the slider drives the upper mold to close with the lower mold to realize the bending of the sheet. The sum of the weight of the left and right columns, the workbench and the sliding block accounts for 70%-80% of the total weight of a bending machine. Its strength and rigidity directly determine the operating accuracy, service life of the machine tool, and the accuracy of the workpiece.
Compared with hydraulic bending machine, the biggest feature of CNC bending machine is its CNC operating system. This is an upgrade of the ordinary bending machine, which reduces the labor of the operator and improves the processing efficiency. But at the same time, the operating requirements and skills of CNC bending machines are much higher than those of hydraulic bending machines, and they are relatively complicated. The CNC bending machine has a multi-step programming function, which can realize multiple automatic operations and complete the one-time processing of multi-step parts.
