Popis: | In the multi-pass conventional spinning process, roller paths have a significant influence on the forming quality of formed parts. The variations of the cone angle of the curvilinear generatrix part make roller path planning difficult. Current researches mainly focus on the design of the roller path profiles and its influence on the wall thickness uniformity of the parts in the one-pass spinning process. It is still difficult to realize the quantitative design of the roller path for the multi-pass spinning process. In this paper, a parametric roller path design method, which can set the mode of starting point allocation, number of passes, roller path profile, backward pass strategy, and gap between the roller and mandrel flexibly, is put forward. The influences of each factor on the forming quality of the curvilinear generatrix parts are further studied based on spinning experiments and finite simulation analysis. The results show that the parametric roller path design method proposed in this paper is an effective way to realize spinning of the curvilinear generatrix parts. Moreover, the backward pass strategy and gap between the roller and mandrel tend to cause lower reductions of wall thickness and better fittability, which can improve the forming precision of the curvilinear generatrix parts significantly. |
