[0002] The characteristics of progressive die type molds are: fast production cycle, high output, and the use of fast presses are its characteristics. The high production efficiency leads to a high wear rate of the punch, which shortens the service life of its wearing parts, increases the inventory cost of wearing parts, and also reduces production efficiency due to the replacement of wearing parts. To deal with this situation, the traditional process is to inject lubricating oil into the rolling felt in the loader to make the sheet itself lubricated, thereby increasing the service life of the punch by reducing the friction with the punch.

Since the oil in the felt reduces the original density of the felt surface, the ability of the felt to clean dirt is reduced, thereby increasing the scrap rate and increasing the cost. Therefore, in order to solve this problem, it is very necessary to design a progressive die pneumatic rhythmic oil injection device. Summary of the invention
