BICHAO型汽车散热器主片成形工艺及二次拽仲模设计

摘要

文章分析了中、小型运输卡车用散热器主片的成形工艺，计算了毛坯尺寸，确定了主片模具工艺方案及模具结构，论述了主片二次拉伸模的结构及工作过程、原理和关键部位的结构设计。实践证明，模具结构合理，生产的零件符合技术要求。%By analyzising the forming process for the main slices of medium and small trucks radia- tors, calculating the blank size and determining the program and mould structure of the main slices, and discussing the structure and work process of the second drawing mould, the structural design of key parts, it is finally confirmed that the mould structure is reasonable and that the production of parts meets the technical requirements.
