AI Technical Summary

Problems solved by technology

Wheel forging is a hot die forging process. The high forging temperature keeps the oil cylinder of the upper demoulding mechanism in a high temperature environment. The oil cylinder seal is rapidly aging due to long-term high temperature environment, resulting in shortened life of the oil cylinder seal, oil leakage from the oil cylinder, and oil leakage. Frequent occurrence, frequent replacement of oil cylinder seals, ultimately affecting production efficiency

Abstract

The invention relates to an automatic cooling system of an upper demoulding mechanism of a wheel forging forming hydraulic press. The automatic cooling system comprises a vane pump, a direction valve and a one-way valve, wherein the vane pump, the direction valve and the one-way valve are connected through an oil path in sequence, the one-way valve is connected with a rod cavity of an ejector cylinder through the oil path, and the ejector cylinder is connected with a sequence valve through the oil path. The rod cavity of the ejector cylinder can be washed continuously, the temperature of the rod cavity of the oil cylinder can be kept in a proper temperature section, the service life of the oil cylinder is prolonged by 4-5 times, and the normal operation of the oil cylinder is ensured.

Description

technical field [0001] The invention belongs to the technical field of hydraulic machine cooling systems, in particular to an automatic cooling system for a demoulding mechanism on a wheel forging hydraulic press. Background technique [0002] In order to meet the hot forging of wheels, the hydraulic press is equipped with an upper demoulding mechanism. Wheel forging is a hot die forging process. The high forging temperature keeps the oil cylinder of the upper demoulding mechanism in a high temperature environment. The oil cylinder seal is rapidly aging due to long-term high temperature environment, resulting in shortened life of the oil cylinder seal, oil leakage from the oil cylinder, and oil leakage. Frequent, oil cylinder seals are replaced frequently, which ultimately affects production efficiency. Contents of the invention [0003] In order to solve the technical problems in the known technology, the present invention provides an automatic cooling system for the dem...
