The function of CNC bending machine and its fault classification

by:WORLD     2022-08-24

The bending machine is a machine that can bend thin plates. The following world press machine will introduce the functions of the CNC bending machine and its fault classification.

Function of CNC bending machine:

The structure of the CNC bending machine mainly includes a bracket, a worktable and a clamping plate. The worktable is placed on the bracket. The worktable is composed of a base and a pressure plate. The base is connected to the clamping plate by a hinge. 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 coil is energized by the wire, and after the power is energized, the pressure plate is attracted, so as to realize the clamping of the thin plate between the pressure plate and the base, in a series of The bending task is completed after the operation of the process, and its operation is also very simple.

The CNC bending machine is much more convenient than the ordinary bending machine. It is fully automatic. You only need to set the program on the computer, then the machine can work continuously without being controlled and supervised, which not only improves the The work efficiency also reduces the workload of the staff. It has many varieties. It can be directly bent during work without splicing, slotting, or welding rods. It turns manual welding into fully automatic machine operation. , improve the quality, improve labor efficiency, reduce costs and shorten the construction period, it is really a very good machine, the continuous progress of science and technology, makes people's life simple and beautiful.

Fault classification of CNC bending machine:

CNC machine tools are highly mechatronic products. Compared with traditional mechanical equipment, although it also includes mechanical, electrical, hydraulic and pneumatic faults, the fault diagnosis and maintenance of CNC machine tools focuses on electronic systems, machinery, pneumatics and even optics. at the intersection of the device.

The common mechanical faults of CNC machine tools mainly include: mechanical transmission fault and excessive friction of guide rail movement. The fault is manifested as large transmission noise, poor machining accuracy, and large running resistance. For example, the coupling of the axial drive chain of the bending machine manufacturer is loose, the gears, ball screws and bearings are lack of oil, the guide rail plug iron is not adjusted properly, the guide rail is poorly lubricated, and the system parameters are improperly set and other reasons can cause the above faults. In particular, the oil filling points marked on each part of the machine tool need to be regularly and quantitatively filled with lubricating oil, which is the guarantee for the normal operation of each transmission chain of the machine tool. In addition, the main failures of hydraulics, lubrication and pneumatics are pipeline blockage and poor sealing.

Electrical faults are divided into weak current faults and strong current faults. The weak current part mainly includes electronic circuits such as CNC device, PMC controller, CRT display, servo unit, input and output device. The strong current part refers to electrical components such as relays, contactors, switches, fuses, power transformers, motors, electromagnets, travel switches, etc. and their circuits. This part of the fault is very common and must be paid enough attention.

The above is the introduction of the world press machine. I hope it will help you to understand the function of the CNC bending machine and its fault classification.
