摘要：
To make the sheet metal can efficiently accurately press forming, Studying onaiming at the designing and optimizing the parameters of TC4 titanium alloy sheet multi-step pressing forming, make the sheet metal can efficiently accurately press forming. This paper analyzes TC4 titanium alloy sheet multi-step pressing forming process and springback mechanism were analyzed, establish and the mathematical model of pressing process and sheet rebound was established,. To obtain the most effective TC4 titanium alloy sheet multi-step pressing forming parameters which satisfy the springback control criteria, build the springback control criteria, thinning thickness control criteria and, thickness deviation control criterion were built, come up with the TC4 titanium alloy sheet multi-step pressing forming parameter design method basing on the springback compensation, obtain the most effective TC4 titanium alloy sheet multi-step pressing forming parameters which satisfy the springback control criteria, thinning thickness control criteria and deviation control criterion. and By takinge the multi-step pressing forming of a special circular tube as an example, to verify the correctness and validity of the proposed method were verified. © 2019, Editorial Department of CIMS.
