一、概述在冲裁加工中,为了得到尺寸精密断面光洁的制件,往往采用整修和精冲工艺。整修工艺是先用普通冲裁法得到毛坯,然后在整修模中进行整修而得到高精度高光洁度制件的。但因整修模间隙极小(一般在0.01毫米以下),而厚板带尖角强度又高的制件需要多次整修,使工艺过程加长,再加上整修时毛坯定位困难,往往即使用多次整修还不
First, an overview In the blanking process, in order to get the size of precision cross-section polished parts, often using renovation and fine-blanking process. Renovation process is to use the ordinary blanking method to get rough, and then in the renovation of the mold to be repaired and get high-precision high-finish parts. However, due to the small gap repair mold (usually 0.01 mm below), and thick plate with sharp corners and high strength parts need to be renovated several times, so that the process of lengthening, together with the rough positioning of the renovation difficult, often use more Times renovation not yet
