| 通过对餐盒零件的分析，确定了零件冲压成形的工艺方案，设计了一副高精度的复合模，解决了在冲压过程中零件材料薄易起皱等问题。论述了模具的结构设计及工作过程，模具采用气压装置提供压边力，提高了毛坯的成形性能，并设计了新型卷边工艺，提高了零件的成品率，实现了该零件生产的顺利进行。 |
| 英文摘要: |
| By analyzing a food container part, its punching forming techniques were ascertained. A high precision compound die was designed. Some problems of a part's thin stuff such as easily wrinkling etc were solved. The structural design and work process of the die were discussed. The pneumatic device was used to provide the mold blank holder force to improve the formability of the blank, and the new curling technique was designed , which increased rate of finished products, and the parts were punched successfully. |
