通过理论分析,概率修正和实验验证,确定出利用柱形凸模、锥形凹模一次拉深锥形件的极限拉深比。文中给出的锥形件一次拉深成形极限拉深比图线和数表,可供生产实用。
Through the theoretical analysis, the probability correction and the experimental verification, the ultimate drawing ratio of the deep-drawn conical part with the cylindrical punch and the tapered concave die is determined. The conical part given in this article is drawing a drawing of the limit drawing line and number table for practical use.
