How to adjust the balance cylinder pressure of 250-ton punch in Jinan No.2 Forging Machine Tool Plant?
The air pressure of the punch balance cylinder can be adjusted according to the weight of the balance slider and the upper die. Generally, there is a nameplate on the punch, and the required intake pressure is adjusted according to the weight of the upper die. Generally speaking, the larger the mold, the higher the air pressure. The air inlet has a high pressure valve for pressure adjustment. After the upper die is installed, the press runs continuously without load, and the handle of the pressure regulating valve is adjusted to make the slider run without filing feeling.
