Abstract：

The 60E1A1 pointed rail heel end is the end of pointed rail connected to the standard guide curve steel rail, and in order to facilitate the connection, the pointed rail heel end needs to be processed into the cross-sectional shape of 60E1 standard steel rail by forging. Therefore, by analyzing the structure and cross-sectional shape characteristics of 60E1A1 pointed rail heel end forgings and comparing the forging ratios of various parts for the cross section, it was found that there were significant differences in the forging ratios among different parts, and it was difficult to form. Then, a process method of die forging composite forming for 60E1A1 pointed rail heel end forgings was proposed, and the die forging process of forgings was numerically simulated by finite element software. Furthermore, the metal flow laws of 60E1A1 pointed rail heel end forgings during initial forging, intermediate forging and final forging processes were comprehensively explored. The results show that this forming process can effectively regulate the metal flow during the forging process, and can control the forming force and temperature changes of forgings during the forging process. Ultimately, the forgings with the required shape can be formed.
