(1. Key Laboratory of Fundamental Science for National Defense of Aeronautical Digital Manufacturing Process, Shenyang Aerospace University, Shenyang 110136, China; 2. School of Mechatronics, Northwestern Polytechnical University, Xi'an 710068, China) Abstract: The spinning process was proposed by analyzing the forming of a typical revolution part, the forming experiment of part was conducted at room temperature, and the experiment material was Al6061. First, the performed shape of part should be identified by the constant-volume principle to calculate the dimensions of blank. Next, the multi-pass spinning and curling process were carried out. Then, the spinning assembly in two forming processes was studied including the selection and design of roller, spindle and tailstock. Finally, the general roller with a 45° installation angle and the multistage roller for curling were selected respectively , which were integrated on the tool holder. However, the spindle with steel 45 should be heat treated, and its work surface needed to be polished. Therefore, the dimensions of spindle were designed according to that of part, and they were corrected based on the springhack value after initial spinning tests. Thus, the tailstock was designed referring to the dimensions of spindle, and the tailstock in the second process had the function of sizing the pre formed billet.

零件工艺分析
在零件制造前，首先要对零件进行工艺分析合理的工序安排及工装设计不仅能够提高生产效率，而且能够提高成形表面的质量及精度。本文选择一种典型的回转体零件作为研究对象，其外形尺寸如图1所示。零件是一种空心旋转体，毛坏材料为 Al6061，板料原始厚度是1.2mm。由于零件的特殊性，采用普通冲压成形方法需要的工装设备比较复杂，首先要将两次拉深集中在一套复合模中，这样的正反向拉深不仅会使坏料减薄严重，而且需要后续的修边和卷边工艺，还造成法兰边起皱失稳，成
