在普通压力机上进行强力齿圈压板精密冲裁新工艺,适用于外形尺寸不大的中小型机电产品零件的批量生产,也是目前我国推广精冲技术之一。简易精冲法根据所使用的设备及模具结构不同,适用范围与加工对象也不一样,详见表1。其设备选用与压力计算方法与在专用精冲压力机上精冲有些不同。为使简易精冲得以推广,选用的设备类型必须符合简易精冲的要求,正确计算所需精冲压力与功,合理确定简易精冲设备类型的具体公称吨位。表1所列前四种简易精冲法是我国目前推广和使
In the ordinary press for powerful ring plate precision blanking new technology for small size of small and medium mechanical and electrical products in mass production, is also China’s promotion of fine blanking technology. Simple fine blanking method according to the use of equipment and mold structure is different, the scope of application and processing objects are not the same, as shown in Table 1. The choice of equipment and pressure calculation method and fine precision stamping press fine punching somewhat different. In order to promote simple fine blanking, the type of equipment used must meet the requirements of simple fine blanking, correct calculation of required fine blanking pressure and work, reasonable to determine the type of simple fine blanking equipment specific nominal tonnage. Table 1 lists the first four kinds of simple fine blanking method is China’s current promotion and use
