在我们生产的产品零件中,有许多是由马氏体类不锈钢2Cr13制造的。这些零件在试制和小批量生产的情况下,对于孔一般都采用镗或铰的方法来加工,对于外形则采用工具磨床来加工成形。随着产品产量的增加,为了提高效率,我们采用了先冲孔落料,然后再冲压整修的加工方法。但是,在实践中,整修的零件光洁度仅能达到?4,远远满足不了零件设计图纸的要求。尽管我们根据冷冲压手册所提供的工艺参数反复试
Many of the parts we produce are made of martensitic stainless steel 2Cr13. These parts in the pilot and small batch production of the hole are generally boring or hinge method of processing, the shape is used to shape the tool grinder. With the increase of product output, in order to improve the efficiency, we use the first blanking blanking, and then stamping renovation processing methods. However, in practice, the finished part finish can only reach? 4, far from meeting the requirements of part design drawings. Although we repeatedly test the process parameters provided by the cold stamping manual
