通过分析突变壁厚旋压圆筒的主要设计指标,计算旋压力后选择了合理的旋压工装,并根据材料极限减薄率设计了旋压毛坯。采用3道次旋压成形的工艺方法,优化了旋压工艺参数,实现了具有突变壁厚筒形件的旋压成形,满足了设计指标。
By analyzing the main design index of the cylinder with sudden change of wall thickness, a reasonable spinning tool was selected after calculating the spinning pressure, and the spinning blank was designed according to the material thinning rate. The three-pass spinning process was adopted to optimize the spinning process parameters and realize the spinning forming with the abrupt wall thickness cylinder to meet the design requirements.
