Forging progress also reflected in the mold manufacturing progress. Generally speaking, the last set of molds average manufacturing time is about 4-5 times the advanced level within the current ring under the standard, the current price in the progress of the ring gear, the main use of a computer and high-speed processing equipment, advanced technology Gear Model mold manufacturing cycles shorten ring gear, die manufacturing concepts resulting changes also improve die life and shorten the molding time is equally important, and maximize the use of inserts die forging. Processing and calculation methods and general configuration of the analysis on the contact boundary compared to simulate forging process is characterized by the contact borders of the workpiece and the die is time varying. This processing and calculations related to the contact boundary friction mechanism, several aspects of contact with the judge out of the search methods and criteria, method to calculate the contact force methods. The low-speed ring, Super League forging (certified), the ring gear forging Luoyang Super League Limited. Luoyang Super League Forging Co., Ltd.
