Supporting hinged shaft forging technology

Abstract

The invention discloses a supporting hinged shaft forging technology. The supporting hinged shaft forging technology includes following steps: (1) chamfering one end of a steel ingot blank, pressing a dead head at the other end of the steel ingot blank so as to form a pincer handle, cutting an unnecessary segment of the steel ingot blank, cutting a water gap, and removing burrs; (2) placing the steel ingot blank into a hole disk, and performing upsetting on the steel ingot blank; (3) fetching out the steel ingot blank, chamfering four edges of the steel ingot blank, rounding the steel ingot blank from all directions, and filing the pincer handle; (4) drawing the steel ingot blank into a pole, forging the pole until steps at two ends of the pole are forged to the designed dimension, and then placing the two ends of the pole into a die, and performing upsetting on the pole; (5) smoothing the two ends of the pole, repeatedly shrinking the pole in all the directions, and using a punch to push double sides of the pole; (6) using a martensite rod to perform chambering twice; (7) smoothing two end faces of the pole, enabling the thickness of the two end faces of the pole to reach the designed size, and inserting the punch into a round inner hole so as to smooth the round inner hole; (8) performing heat treatment after the size of the pole is qualified through measurement. The supporting hinged shaft forging technology has the advantages of being simple and convenient, can be used to directly obtain a qualified product through a forging method, prevents lathing from damaging tissue fibers of the product, prolongs use life of the product, and simultaneously reduces a processing volume, saves materials, and reduces cost.

Description

technical field [0001] The invention relates to a forging process, in particular to a support hinge shaft forging process. Background technique [0002] The main steps of the existing supporting hinge shaft forging process are: first forging the rough material into an octagonal forging, and then putting it into a lathe to cut and shape the bearing installation position. Although the product can be formed in this way, there are following deficiencies in such a process: 1. The processing amount is large, resulting in long processing time; 2. When turning on a lathe, the amount of material waste is large, which wastes materials and improves the processing efficiency. 3. During the turning process, the fibrous structure of the forging is destroyed, which affects the quality of the forging, resulting in a shorter service life of the product. Contents of the invention [0003] The object of the present invention is to provide a support hinge shaft forging process capable of...
