Abstract：

Multi-way tube on air conditioning header is considered as the research objective. Finite element simulation method was utilized to simulate and analyze the deformation process for metal. Through analyzing the thickness distribution law of workpiece and displacement law of typical nodes, the common law in deformation process for metal flow was revealed. The results show that the metal on the zone of outer side supplementary conspicuously flows along horizontal，on the zone of forming conspicuously flows along bulge, and the metal which is between bulges flows little. The above laws supply references for choosing forming technology.
