If the round pipe punching machine used by the enterprise has the specified special hydraulic oil, the special hydraulic oil should be used according to the requirements instead of mixing with other types of hydraulic oil. Zhejiang major Numerical control punching machine for zinc steel guardrail If the round pipe punching machine does not have the specified hydraulic oil, the appropriate hydraulic oil brand can be selected according to the working environment and working conditions of the hydraulic system. After selecting the type of hydraulic oil, the enterprise must also determine the viscosity of the hydraulic oil required by the pipe punching machine. Numerical control punching machine for zinc steel guardrail The viscosity should be selected according to the temperature range of the geographical location. Generally speaking, the thinner hydraulic oil can be used in the northern region, and the hydraulic oil with a slightly higher viscosity can be used in the southern region. Because the temperature in the north is low, if the viscosity of the hydraulic oil is high, it is not conducive to the operation of the hydraulic system in the low temperature environment.

For CNC punching machine equipment, quality is the hard truth for enterprises to survive. Therefore, we must ensure the stability of product quality. Equipment and materials of CNC punching machine; Due to the increased cost of current materials, Zhejiang Numerical control punching machine for zinc steel guardrail Price Some enterprises will start with raw materials and choose inferior materials to replace them. The result is that the product quality is not guaranteed. Before using the automatic CNC punching machine, be sure to check whether there are sundries at the punch and the lower die edge. Add lubricating oil to the upper and lower moving parts of the punch. Numerical control punching machine for zinc steel guardrail During use, keep the oiling part of the numerical control punching machine free of oil shortage. At the same time, it should be noted that after the use of the NC punching machine is completed, the NC punching machine should be cleaned first, and the punch should be pressed down to the low position to better protect the NC punching machine.

In order to ensure that the round pipe punching machine has good quality and use effect, it is recommended that enterprises choose genuine hydraulic oil with relatively high cost performance. Because the hydraulic oil with good brand has high purity and less impurities, it will not be worn by impurities after being used for the round pipe punching machine, and the oil is not easy to deteriorate, Zhejiang Numerical control punching machine for zinc steel guardrail Can play a better role. As the hydraulic system is an important part of the pipe punching machine, and the hydraulic oil plays a crucial role in it, major Numerical control punching machine for zinc steel guardrail When using the round pipe punching machine, enterprises should not only use the equipment according to the operating rules, but also pay attention to adding and replacing the hydraulic oil in the hydraulic system regularly to ensure that the quality and life of the round pipe punching machine will not be affected.

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. Zhejiang Numerical control punching machine for zinc steel guardrail Price 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). Numerical control punching machine for zinc steel guardrail 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).
