对节距190mm链轨节模锻成形过程进行数值模拟,获得了链轨节模锻成形过程金属流动规律;对成形过程中出现的折叠缺陷进行分析,对冲孔连皮及预锻毛坯结构进行优化,解决了折叠缺陷问题;结合生产实践设计了链轨节的锻造模具。经实践检验,生产出的锻件符合技术要求。同时,改进后的锻造模具节约了原材料,降低了生产成本。 Numerical simulation of die forging process of 190 mm pitch link section was carried out to obtain the rule of metal flow during die forging process of chain link section. The folding defects occurred in the forming process were analyzed to optimize the structure of punched cope and pre-blank , To solve the problem of folding defects; combined with production practice designed forging section of the link die. After testing, the forgings produced meet the technical requirements. At the same time, improved forging dies save raw materials and reduce production costs.
