【摘要】：采用不同的模具预热温度、始锻温度和终锻温度对Cu-Zn基汽车同步器齿环进行了锻造,并进行了磨损性能和冲击性能的测试与分析。结果表明:在试验条件下,随模具预热温度从200℃升高至300℃、始锻温度从720℃升高至800℃或终锻温度从590℃升高至710℃,齿环的磨损性能和冲击性能均先提高后下降。Cu-Zn基汽车同步器齿环的最佳工艺参数为:模具预热温度275℃、始锻温度780℃、终锻温度690℃。
[Abstract]:Different preheating temperature, starting forging temperature and final forging temperature were used to forge the gear ring of Cu-Zn based automobile synchronizer, and the wear and impact properties were tested and analyzed. The results show that under the test conditions, the wear and impact properties of the ring are tested and analyzed. With the increase of preheating temperature from 200 鈩，
