What is the reason why the pressure drop of CNC bending machine is too fast?

In the whole process of research and development of CNC bending machine, it is found that the parts are in place in the production process, and then carry out inspection. There is no difficulty in checking the abrasive tools first. Press and hold the sliders of the four column CNC bending machine to remind the large working pressure.

According to the running test, it can be seen that there is no problem in the guide slide and hydraulic press pad. Check the water content of gear oil, and find that the oil content of gear oil in e-mail box is up to standard. The problem that can be identified is: "the gate valve involved in the maintenance of working pressure is not severe or the pipeline leaks or the internal cylinder seal is damaged."

Therefore, please check the tank valve and the tightness level of the pressure reducing valve according to the fuel pipe drawing in the actual operation instructions. After the inspection, it was found that there was a leakage in the oil pipeline, which resulted in a serious leakage of gear oil and a rapid reduction of working pressure.

CNC bending machine is generally composed of three parts: itself, power device and hydraulic transmission system. The utility model is generally composed of a sound card frame, a hydraulic cylinder component, a part of fitness exercise, a guiding device and other auxiliary tools. The key elements of the manufacturing process which are harmful to the construction of the CNC bending machine itself. Because the processing technology on different NC bending machine is various, the structure of NC bending machine is different.

According to the way of sound card frame, CNC bending machine can be divided into column type and vertical type; according to the way of sound card frame, CNC bending machine can be divided into column beam type, single column type, frame structure type, stainless steel wire wound prestressed reinforced stone arch type, etc. The shell is composed of operating platform, guide rail slide block, upper bearing beam, vertical bar, lock nut, adjusting nut, etc.
