The function and principle of the master cylinder of hydraulic press

The master cylinder of hydraulic press is the main working part of hydraulic press, the performance of the master cylinder of hydraulic press directly affects the whole process level of hydraulic press. Through careful analysis and theoretical research to solve the problems in the design structure of the vulnerable part, the hydraulic cylinder can meet the requirements of process strength as a whole, and improve the process level and service life of the hydraulic cylinder. Therefore, the careful and rigorous design and calculation of the master cylinder of the hydraulic press plays a crucial role in the design and production of the hydraulic press.

When the master cylinder slider of hydraulic press fast-forward, the speed is relatively fast under the action of self-weight, and the output oil of hydraulic pump at this time can not meet the rapid downward movement of the slider. The fast forward load of the master cylinder of the hydraulic press is very small, only the friction load between the piston and the cylinder, the guide rod and the slider, so that the outlet pressure of the pump is also very small, and the power consumption will not be very large

When the piston rod of the hydraulic press is fully extended, the distance from the midpoint of the piston support surface to the midpoint of the sliding support surface of the cylinder head is called the minimum guiding length, which is expressed by H. If the guide length is too small, the initial deflection of the hydraulic cylinder will increase due to the deflection caused by the clearance, affecting the stable operation of the hydraulic cylinder.
