|
The characteristics of bumps and dimples appear on the surface of the complex skin part which is difficult to be formed with highly requirements. In order to solve the above problem, the forming process of the complex skin part was analyzed and discussed in detail, and the stretch forming was studied from the aspects of forming scheme, forming equipment, forming tooling, force characteristics and forming parameters by combining the structural features of the part and the difficulty of forming. Furthermore, the possible technical problems were analyzed to give the solutions, and the optimization scheme and improvement method were presented in combination with the actual situation. In the end, the forming defects such as coarse-grain and wrinkling of the complex skin part in stretching forming process were avoided by adopting the optimized scheme, and good application was realized in production.
