STUDY ON TECHNOLOGY OF MULTI-WEDGE CROSS-WEDGE ROLLING OF AUTOMOBILE SEMI-AXIS SHAFTS
Abstract
With rapid development of automotive industry, the demand of automobile semi-axis is increasing. However, it increases the cost investing in dies as automobile semi-axis are stile produced with single-wedge cross-wedge rolling. Therefore, the study on deformation of MCWR forming automobile semi-axis is of great significance. The software PRO/E is adopted in setting up three-dimensional model, with the advanced explicit dynamic finite element DEFORM, the simulation of rolling automobile semi-axis with MCWR was analyzed systematically. The influence of rolling parameters on rolling force were attained by a practical computed method. It was shown that side wedge forming angles and side wedge transition angles had little influence on the force, the coefficient friction had critical influence on force.
