一、复合切边和校正概述模锻件在切边后大多均有不同程度的变形,变形严重的就必须进行校正。每个工厂根据自己的设备条件和技术要求,在切边后可以再放入终锻模膛中热校正一下;也可以在另一台锤或压床的校正模中校正;还可以最后在专用校正锤或压床上进行冷校正。为了提高劳动生产率,省去单独的校正工序,国内外已有一些工厂采用了切边和校正的复合工艺。实践证明这是提高劳动生产率的简单而又有效的 First, the composite trimming and correction Overview Forging parts in the trimming after most of them have varying degrees of deformation, serious deformation must be corrected. Each factory according to their own equipment conditions and technical requirements, after trimming can be placed in the final forging die bore thermal correction; can also be another hammer or press correction model calibration; but also the last dedicated Correction hammer or press for cold correction. In order to improve labor productivity, eliminating the need for a separate calibration process, some factories at home and abroad have adopted a trimming and correcting composite process. Practice has proved that this is simple and effective in raising labor productivity
