摘　　要：弯管在航空、船舶、汽车等行业应用广泛,随着航空、船舶、汽车业的蓬勃发展,对弯管的需求也越来越大。为了解决弯管推弯过程中薄壁管外侧拉裂、内侧褶皱的问题,本文研究设计了一款同时对弯管内侧壁冷却、外侧壁加热的铝合金薄壁管差温推弯模具,可以更好地提高推弯成形质量。同时,为了解决模具单一性导致的弯管生产效率较低的问题,本文利用VB技术对CATIA进行二次开发,对所设计的铝合金薄壁管差温推弯模具进行参数化设计,实现通过所需弯管尺寸的变动来驱动生成相应的模具,以提升生产效率。Bend pipes are widely used in industries such as aviation,shipbuilding and automotive.With the vigorous development of aviation,shipbuilding and automotive industries,the demand for bend pipes is also increasing.In order to solve the problems of cracking on the outer side and wrinkling on the inner side of thin-walled pipes during the bending process,this paper studies and designs an aluminum alloy thin-walled pipe differential temperature bending mold that simultaneously cools the inner wall of the pipe and heats the outer wall,which can better improve the forming quality of the bending process.At the same time,in order to solve the problem of low production efficiency of bending pipes caused by the singularity of the mold,this article uses VB technology to conduct secondary development of CATIA and parameterize the designed aluminum alloy thin-walled pipe differential temperature push bending mold,achieving the corresponding mold generation driven by changes in the required bend size to improve production efficiency.
