本文利用反印法原理,测定并比较了常规毛边槽和扩张形毛边槽的磨损。检测表明,用扩张形毛边槽模锻时,其毛边部分磨损比常规毛边槽耍少30～50％,因而这种毛边槽具有减少变形力、提高模具寿命的优点。本文还从理论上推导了用扩张形毛边槽模锻时的变形力计算公式并进行了实验验证。实验表明,计算公式的误差不超过15％,可作为选择模锻设备时的参考。 In this paper, the principle of anti-imprinting method was used to determine and compare the wear of conventional burrs and expansion burrs. The testing shows that when burrs are expanded by the expanded burrs, the burrs of the burrs are 30 ~ 50% less worn than the conventional burrs, so that the burrs have the advantages of reducing the deformation force and improving the service life of the mold. In addition, the calculation formula of deformation force in the process of die-forging with expansion-shaped burrs is deduced theoretically and experimentally verified. Experiments show that the error of the calculation formula does not exceed 15%, which can be used as a reference when selecting forging equipment.
