中文摘要: |
薄壁深锥形件的拉深属于复杂零件的拉深,为了解决该类型零件在引深过程中易出现的变薄、拉裂和疲劳现象,以及材料难以流动等问题,通过对锥面依次成型工艺的研究,采用了锥面一次成型法,制定完整的工艺方案及模具结构,经实践证明是行之有效的。对类似零件成型时出现的失稳、起皱和开裂现象具有一定的借鉴意义。 |
英文摘要: |
Drawing of thin deep wall cone tube is a kind of complex drawing parts. In order to solve the problems of occurred in deepening process such as getting thinner, splitting , fatigued, and slowly flowing of the material, the paper worked out a complete processing plan and mold structure through study of cone orderly forming processing , thus adopted one time shaping method which is verified by practice, and so can be available a reference to improve the defect such as instability , wrinkling and fracturing and paper die structure. |
