In the process of hydraulic system control of CNC bending machine, we should pay attention to the use of low noise hydraulic components. How to judge whether the hydraulic system of the plate bending machine is faulty? The plate bending machine manufacturer can listen to whether the noise of the hydraulic pump and hydraulic system is too large, whether the pressure control components such as overflow valve and sequence valve have screams, and whether the impact of the hydraulic cylinder on the worktable is too large, whether the piston has the sound of hitting the bottom of the cylinder, and whether the valve has the phenomenon of hitting the end cover when reversing.

Plunger pumps or gear pumps are still used in many CNC machine tool hydraulic systems. In view of this situation, it is necessary to improve the rated pressure of vane pumps, at least to ensure that the rated pressure is about 20MPa, so as to reduce vibration and noise. Secondly, the numerical control four roller bending machine to control the number of hydraulic pumps. Through research, it is found that vibration and noise will be reduced when the number of hydraulic pumps is reduced.
Do a good job in setting up the damper and filter. Generally speaking, there are many ways for the damper. The damper that can be used includes high-frequency pressure damper and micro-perforated liquid damper. Full CNC four roller bending machine in the practice of the common filter hydraulic filter, the use of these devices can greatly reduce the vibration and noise.
In the traditional hydraulic system needs to adjust the flow and pressure by means of multiple hydraulic pumps, in order to ensure the flow and pressure of the hydraulic pump, the pressure and flow can be adjusted according to the share, so as to reduce the number of hydraulic pumps.
