The maintenance of the hydraulic rack punching machine can greatly delay the reduction of the accuracy of the hydraulic punching machine and extend its service life. The reduction of hydraulic punching machine precision is mainly manifested in the wear and plastic deformation of punching machine parts. Foshan Rack punching machine manufactor Therefore, the lack of maintenance is one of the reasons why the accuracy of the NC punching machine is reduced. You can combine your own situation to see whether this is the reason for the reduction in accuracy. The movement relationship (time and movement) between components is damaged due to grinding and deformation of components, major Rack punching machine It will also reduce the accuracy of the hydraulic rack punching machine. Numerous practical experiences have proved that the accuracy of hydraulic punching machines without maintenance or improper maintenance can reduce much faster than that of well maintained hydraulic punching machines.
During commissioning, it is not necessary to feed materials, but it is necessary to first raise the guide screw on the guide plate, and then gradually adjust the ram of the punch to the bottom dead center by inching. It is necessary to pay special attention to that the guide plate should not press the floating rod too low, otherwise the floating rod will be bent or broken. major Rack punching machine manufactor When starting the punching machine for continuous punching, it is necessary to rotate the speed adjusting screw of the nc servo feeder clockwise. The slider moves slightly slowly, so that it can be seen whether the slider touches the nylon gasket and the length adjusting screw when it moves back and forth. Rack punching machine If the full-automatic punching machine only touches the length adjusting screw but not the nylon gasket when the sliding block moves back and forth, it is because the floating rod is lowered too deep, and the guide screw on the punching machine needs to be gradually raised.
When the parts of the pipe punching machine are working, under the rated working conditions, they will not be damaged in any form, nor will they produce residual deformation beyond the allowable limit, and can ensure the normal operation and work of the machine, so it is considered that the parts meet the strength requirements. Foshan Rack punching machine In design, most important parts are checked by strength conditions (relevant strength theory in engineering mechanics), except some parts with small force or complex shape that cannot be calculated are determined by experience and experiments. major Rack punching machine If the strength of the parts is not enough, the overall fracture, surface contact fatigue or plastic deformation and other failures will occur and the working ability will be lost, so the strength requirements must be met when designing the parts.
The insufficient strength of the punching machine for zinc steel guardrail is the direct cause of the fracture or excessive residual deformation of the parts in work. Foshan Rack punching machine manufactor The strength of parts is divided into volume strength and surface contact strength. For example, if the stress produced by the pipe punching machine parts under the load is within a large volume, the strength of the parts under this stress state is called volume strength (strength for short). Rack punching machine If two parts change from point contact or line contact to small surface contact before and after being loaded, and their surfaces produce large local stress (called contact stress), then the strength of the parts is called surface contact strength (called contact strength for short).
When purchasing a NC punching machine, some details need attention. A small detail that is not paid attention to may affect the service life of the NC punching machine. Here is a detail that is easy to be ignored, that is, the polishing of the machine's steel plate, major Rack punching machine manufactor Some people may think that as long as the mold is finished, there will be no problem. It is not important whether the steel plate is ground or not, but in fact, this is not the case. If the steel plate under the mold is not ground smoothly, Rack punching machine It is likely to affect the service life of the mold, so it is likely to fail in the future use process.
The lubrication function of the pipe punching machine will be gradually weakened after long-term use, which will lead to increased friction and damage in the process of equipment operation. Even professional pipe punching machines are not immune, Foshan Rack punching machine Therefore, in order to avoid this kind of situation, it is necessary to add lubricant in time, especially the position of the punch to maintain lubrication, reduce friction and extend the service life of the equipment. The pipe punching machine is the most taboo to be impacted by foreign objects. Even if the impact degree is not large, component failure is likely to occur. Rack punching machine manufactor Therefore, whether before or after use, check whether there is any foreign matter between the punch and the lower die, and use carefully to prevent the punch from being damaged due to the extrusion of the punch and the lower die caused by foreign matters.
