Large-Size Wheel Rotary Forging Process Research

Abstract:

For forging process of the large size alloy wheels have several disadvantages, such as using large tonnage presses, high energy consumption, etc.So rotary-forging process route is developed. Forgings forming require 5000-6000T presses by the traditional process, but only require 350T rotary forging presses by new technology. This new process reduces the production costs and energy consumption and extends the life of die. Investigate the effect of several key factors on the forming force. The results show that forming force decreases with the decrease of press amount per turn, and reduce with the die and bars temperature increases. Forging wheel window has small influence on the forming force, but can decrease the forgings cutting weight, improve material utilization. This study plays a guiding role for equipment R & D and determination of the production processes parameters.
