Abstract：

This paper has introduced the process experiment result analysis of precision roll forging and for YQ153A front axle, In the process trial, many problems were solved, the problems include the insufficient width and thickness of the spring seat, fold, scraping material, the unfilled sections and the asymmetry of the joist, the bending of the 1 st step billet, the reversing material of the 2 nd and 3 rd step And last, in addition to reduce the length of the middle part of the roll forging die according to the actually situation, the satisfied roll forged forgings were manufactured
