油箱的液压成形工艺及模具设计

Fueltanks hydioform ciaft and mold design

板材液压成形属于先进的软模成形技术，具有广阔的应用前景。本文通过有限元分析，对摩托车油箱成对液压成形工艺进行了较为深入的研究，提出了较为优化的工艺参数。在此基础上，提出了对复杂箱体零件的成对液压成形的新工艺方法及高压密封结构，并设计了摩托车油箱成对液压成形模具装置。

Sheet metal hydroforming is an advanced flexible die forming technique which has extensive potential application. In this paper, we have much analyses of hydroforming in pairs of the motorbike tank by finite element method and put forward optimized processing parameter of forming. On this base, the new method of tank forming and the high duty seal structure of complicated case body were put forward, also the device of sheet metal hydroforming in pairs is designed which is simple and reliable.
