摘要：

为解决一种车用法兰盘零件传统制造工艺效率低、材料利用率低、生产成本高、产品使用性能差等问题，设计了一种3工位热模锻成形工艺，依次经预成形、预锻、终锻成形。为保证工艺质量，利用Deform3D软件对法兰盘零件的成形过程进行了模拟，根据金属变形过程确定了工艺中的隐藏缺陷；对预锻模具结构进行了优化，提出了两种改进方案，同时依次进行了成形检验，并对比了改进后两种方案的终锻件的温度分布、预锻和终锻工位的锻造力及模具磨损情况。结果表明，改进后工艺可解决锻造缺陷，并且采用改进方案2，对法兰盘锻件质量的提高和模具寿命的延长更有帮助。最后，进行了法兰盘零件的热模锻试验，得到了符合预期的法兰盘零件，有效解决了目前面临的难题。

In order to solve the problems of low efficiency, low material utilization, high production cost and poor product performance in the traditional manufacturing process of an automotive flange part, a three-station hot die forging process was designed, which consists of preforming, pre-forging and final forging in sequence. Then, to ensure the process quality, the forming process of flange part was simulated by software Deform-3D, and the hidden defects in the process were determined based on the metal deformation process. Furthermore, the pre-forging die structure was optimized, and two improvement schemes were proposed. At the same time, the forming inspection was carried out in turn, and the temperature distribution of final forgings, the forging force of pre-forging and final forging stations, and the die wear conditions of the two improved schemes were compared. The results show that the improved process solves the forging defects, and the improvement scheme 2 is more helpful to improve the quality of flange forgings and prolonging the life of die. Finally, hot die forging tests of flange parts are carried out, and the expected flange parts are obtained, which effectively solves the current problems.
