面包箱左右侧板成形工艺及模具设计

The Forming Process for the Left and Right Side Plates of the Bread Box and the Design of the Die

通过对圆筒形和矩形组合拉伸件的工艺计算和分析 ,确定了合理的工艺方案 ,同时介绍了模具的结构特点及工作过程 ,并充分利用工件相互对称的特点 。

Through the technological calculation and analysis of the drawn parts combining cylinder and rectangle, a rational technological process was determined. The structure characteristics and working process of the die were introduced. The number of the dies was decreased by fully taking advantage of the symmetry of the parts.
