China punching machine manufacturer

Punching machine is an important metal processing equipment, mainly used for stamping, shearing, bending, stretching and other forming processes of metal materials such as plates, strips, pipes and profiles. There are two main lubrication methods for punch ball heads: immersion lubrication and circulating lubrication cooling structure. The following is a detailed introduction of China punching machine manufacturer:

1. Oil immersion lubrication

Immersion lubrication is a traditional lubrication method, which stores lubricating oil in the oil chamber at the upper part of the punching machine, and then relies on gravity to make the lubricating oil flow downwards, lubricating the ball head, ball bowl and other parts. However, this lubrication method has some drawbacks. Firstly, lubricating oil cannot be recycled, which leads to wastage of resources. Secondly, when the punching machine operates at high speed and heavy load, the relative movement speed of the ball head and bowl is fast, and the gap between the contact surfaces approaches zero, making it difficult for lubricating oil to enter the contact surfaces. Therefore, problems such as heating, rapid wear, and burns of the ball head and bowl are prone to occur. These issues will affect the operational accuracy of the slider, thereby affecting the normal operation of the punching machine.

2. Circulating lubrication cooling structure

In order to address the drawbacks of oil immersion lubrication, most punching machines now adopt a circulating lubrication cooling structure. The principle of this structure is that the lubricating oil enters the punch slide cylinder through the oil inlet pipe of the self-lubricating pump station, and then enters the piston cavity along the piston port on the side of the hydraulic pad piston. When the lubricating oil continuously enters and the oil pressure in the piston chamber reaches a certain value, the lubricating oil will rise along the through oil hole of the guide column screw and then enter the lower ball bowl for lubrication. The lubricating oil continuously flowing out of the lower ball bowl continuously rises in the space formed by the upper and lower ball bowls. When the oil pressure reaches a certain value, the lubricating oil will flow back into the lubrication pump station along the return pipe, thus achieving the circulation lubrication of the lubricating oil.
The circulating lubrication cooling structure can not only improve the lubrication effect, reduce the wear and heat generation of the ball head and bowl, but also save resources because the lubricating oil can be recycled. In addition, this structure also helps with the heat dissipation and cooling of the punching machine, improving its efficiency and stability.
In summary, for the lubrication method of the punching machine ball head, it is recommended to choose a cyclic lubrication cooling structure to improve the lubrication effect, save resources, and improve the working efficiency of the punching machine. At the same time, it is important to regularly inspect and maintain the lubrication system during use to ensure the cleanliness and adequacy of the lubricating oil, as well as the normal operation of the lubrication system.
