How can the cutting power of hydraulic cutting machine be insufficient?

I believe you have also tried the same product hydraulic cutting machine suddenly cut. Today, the Honggang cutting machine will analyze and solve this difficult problem for you.

There are three reasons for the cutting force of hydraulic cutting machine.

First, the pressure drop of the hydraulic system, the pressure drop of the hydraulic system in addition to the cause of "failure", but also due to the pressure setting low or failure of the high pressure relief valve, the method of removing the barrier is to clean the body and its inner parts to eliminate the blockage, and to replace the new valve when necessary. When the relief valve is re installed, the pressure gauge must be connected to determine the working pressure.

Two, oil cylinder oil leakage is serious, oil cylinder leakage of oil has two kinds of leakage and leakage, that is, the seal ring damage of the cylinder causes internal leakage, resulting in the reduction of blanking force, as long as the replacement of the seal failure can be eliminated.

Three, the pressure relay leads early to make the punch return early, the pressure relay or the delay device pushes the cylinder back early through the electromagnetic reversing valve, and does not produce punching force against the knife die, which causes the doubtful punching force to be insufficient and has nothing to do with the hydraulic system. As long as the delay knob is adjusted accurately or the new high-precision time delay relay is replaced, the breakdown of the blanking force can be eliminated.
