1991年贵州家电总厂开发温控杯,其内胆为Cr18Ni8奥氏体极薄不锈钢板的拉延件(厚度= 0.4m),由于技术难度大工艺过程复杂,厂方经过半年多,找了许多单位均未能解决该技术难题。 经重庆市招标公司牵线,重庆大学机械工程二系邱忠义,孙伦宝副教授等同志在系成形加工厂的配合下,于1991年8月开始了此项研究。经过一年多的努力,对一万多件产品的实际检验,该课题于1993年5月11日顺利通过了四川省教委组织的专家鉴定。 In 1991, Guizhou Household Appliance General Factory developed a temperature control cup. The liner is a drawn piece of Cr18Ni8 austenitic ultra-thin stainless steel plate (thickness = 0.4m). Due to the technical difficulty and complicated process, the factory has been looking for more than six months Many units failed to solve the technical problem. Pursued by the bidding company of Chongqing Municipality, Chongqing University Department of Mechanical Engineering Qiu Zhongyi, Associate Professor Sun Lunbao and other comrades in the Department of forming processing plants in cooperation, in 1991 August began the study. After more than a year of hard work, more than 10,000 products of the actual test, the subject on May 11, 1993 passed the Sichuan Provincial Board of Education experts identified.
