三、正确地选择锻造设备负荷从金属塑性变形原理可知,对于变形力和变形功的理论计算极为复杂,而胎模锻由于工艺灵活,所以目前还没有一个比较准确和简便的计算方法和图表。尤其中小型锻造车间,设备的台数往往满足不了生产的要求,经常出现小设备干大活的情况,所以很难确定统一的计算方法,只能作出大致的定 Third, the correct choice of forging equipment load From the plastic deformation of the principle we can see that the theoretical calculation of the deformation force and deformation work is extremely complex, and tire die forging process flexibility, so there is not a more accurate and simple calculation methods and charts. In particular, small and medium-sized forging workshops, the number of equipment often can not meet the requirements of production, small equipment often appear dry situation, it is difficult to determine a unified method of calculation, can only make a rough decision
