【摘要】：采用不同的模具預(yù)熱溫度、始鍛溫度和終鍛溫度對(duì)Cu-Zn基汽車同步器齒環(huán)進(jìn)行了鍛造,并進(jìn)行了磨損性能和沖擊性能的測(cè)試與分析。結(jié)果表明:在試驗(yàn)條件下,隨模具預(yù)熱溫度從200℃升高至300℃、始鍛溫度從720℃升高至800℃或終鍛溫度從590℃升高至710℃,齒環(huán)的磨損性能和沖擊性能均先提高后下降。Cu-Zn基汽車同步器齒環(huán)的最佳工藝參數(shù)為:模具預(yù)熱溫度275℃、始鍛溫度780℃、終鍛溫度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，
