我院金材系热处理教研室刘心治、张世学老师与成都峨眉自行车厂合作,对自行车幅条孔冲头生产进行了试验研究。两年多来在取得大量数据的基础上,终于找到了一条最佳工艺流程及从原材料到成品的综合强韧化生产新工艺,使冲头一次刃磨寿命由原来平均5000次/支提高到平均12万次/支以上,最高达154520次/支,提高使用寿命20～30倍,达到了国内先进水平。1987年10月由成都市一轻局主持召开了有成都科技大学、成都市热处理学会、热加工研究会及冲压学会等单位的13位专家参加的鉴定会。
Our hospital heat treatment department of gold Liu Xinzhi, Zhang Shixue teacher and Chengdu Emei bicycle factory cooperation, bicycle punched hole punch production test. In the past more than two years to obtain a large number of data on the basis of finally found an optimal process and from raw materials to finished products comprehensive toughness of the new production process so that the punch a sharpening life from an average of 5000 times / support increased to An average of 120,000 times / branch or more, up to 154520 times / branch, improve the service life of 20 to 30 times, reached the advanced level in China. October 1987 hosted by Chengdu Bureau of Light Bureau held a Chengdu University of Science and Technology, Chengdu Heat Treatment Society, Thermal Processing Research Association and Stamping Society and other units of 13 experts to participate in the appraisal.
