Abstract: |
The hot forming process of TC4 tie-in is imitated using PAMSTAMP simulating software. The influences of forming temperature and the part structure are analyzed. The higher temperature and the more gentle shape, the better shape. The superior drawing parameters are acquired by simulating, and the forming result is improved. |
