| 中文摘要: |
| 分析了排气管法兰的结构特点及技术要求，确定了该零件的复合冲压成形工艺方案，即外缘翻边、拉深、冲孔、圆孔翻边。设计的复合模先后完成以上冲压工序。详细介绍了复合模具的结构特点、工作过程、设计要点及注意事项。经实际生产验证，该模具显著提高了生产效率和产品质量，给企业带来了显著的经济效益。 |
| 英文摘要: |
| After a study on the design features and technical requirements of a exhaust pipe flange，the compound stamping forming process was determined. The designed compound die could be used to complete four procedures of the outer edge of flanging, the drawing, punching hole and hole flanging in turn. The compound die features of structure, working process, main design points and notices to produce were introduced in detail. After the actual production, it was found that the die greatly improved the production efficiency and quality of product. The economic benefit of company was improved. |
