摘要
落料线是用来将冷轧钢卷开卷、落料、剪切加工的生产线,主要为汽车企业提供落料压力成形及板材剪切服务。随着用户对汽车板质量要求的提高,汽车主机厂对落料剪切板料的尺寸要求越来越严格,落料线在板料的尺寸精度控制方面存在一些不足。本文针对梯形板料尺寸超差方面的缺陷,从梯形板料尺寸理论和实际控制方面进行分析,改进梯形产品生产的工艺和设备,使梯形板料尺寸生产合格率提高,提高落料剪切加工质量的稳定性,促进了板料质量的提升,满足了汽车厂客户的要求。
The blanking line is a production line used for uncoiling,blanking and shearing of cold-rolled steel coils.It mainly provides blanking pressure forming and sheet cutting services for automobile enterprises.With the improvement of users*requirements for the quality of automobile sheets,the size requirements of the automotive OEMs lor blanking and shearing sheets are becoming more and more stringent,and the blanking line has some deficiencies in the control of the dimensional accuracy of the sheets.Aiming at the defects of trapezoidal sheet size out of tolerance,the trapezoidal sheet size theory and actual control have been analyzed in the text.The process and equipment of trapezoidal product production have been improved to raise the qualified rate of trapezoidal sheet size production.The stability of the blanking and shearing quality have been improved to promote the improvement of the quality of the sheet metal,which meets the requirements of the customers of the automotive factory.
