Abstract

The invention relates to a semi-closed forging device for a universal joint and a forging method thereof. The semi-closed forging device comprises a bench, an ejection mechanism, a lower die base, a lower drill key, a lower die, an ejector rod, an upper die, an upper drill key, an upper die base and a hammer head, wherein, the bench is equipped with a T-slot; the lower die base is fixed on the bench through screws; a connection slot is aligned with the T-slot; the lower die is fixed on the lower die base through the lower drill key, and the upper die is fixed on the upper die base through the upper drill key; the upper die base is fixed on the hammer head through bolts; the ejector rod is placed in a circular hole in a lower die cavity and pushed for ejection and restoration when the ejection mechanism moves up and down; and the lower die, the lower die base and ejector holes of the bench are communicated correspondingly. The device and the method of the invention can help achieve high machining precision and high qualification rate of the universal joint product.

Description

technical field [0001] The invention relates to a process method for a forging station of mechanical processing equipment, in particular to a process method for a cross shaft semi-closed forging processing device in the cross shaft processing of forging equipment. Background technique [0002] The automobile industry is a pillar industry and a leading industry in the industrial industry. The gross production value of the automobile industry has played a pivotal role in the development of my country's national economy. Therefore, the automobile industry is constantly improving the production process of the cross shaft to make the processing of the cross shaft more reasonable. Now the forging process of the cross shaft is innovated; The shape of the shaft is complex and the branches and forks are more flashes formed during pre-forging, so that the material utilization rate is low and the average is only 70%. Contents of the invention [0003] In order to overcome the shortco...
