阐述了烧结体密度分布与精整尺寸精度的关系,材料抗拉强度与精整尺寸精度的关系;入口形状为圆弧的整形模其入口曲率半径R的选择和入口形状为锥度的整形模其入口角度的选择,以及精整中消除喇叭口的措施。
The relationship between the sintered compact density distribution and the precision of the sizing, the relationship between the tensile strength of the material and the precision of the sizing are expounded. The selection of the entrance radius of curvature R and the shape of the inlet with the entrance shape as a circular arc are as follows: The choice of entrance angle, as well as the elimination of the bell in the finishing measures.
