Abstract：

In order to achieve the goals of reducing the frequency of repeated operations for on-site trial production, size adjustment, process exploration in the traditional forging production of titanium alloy crank elbow forgings, and to solve the problems of long cycle and large loss, the finite element analysis software was used to simulate the press forming process of the normal open die forging hammer to assist the optimization of the pattern, the probability of product defects and the number of actual trial production were reduced. The risk of production defects which might occur in the forming process was reasonably reduced after attempting different design schemes of preformed blank and analyzing the influence of different preformed blank on the final die forming effect one by one. Through the combination of numerical simulation and process test, a new kind of diamond preformed blank scheme was obtained, that was, firstly, the bar was forged into a diamond-shaped blank, and then the physical and chemical detection area was removed by mechanical processing, and finally a suitable preformed blank was obtained by shaping with double leak plates. This kind of preformed blank has realized engineering application in the forming method.
