扼要介绍了摆动辗压成形过程的工作原理及摆头运动轨迹 ;详细分析了摆头运动倾角(即摆角 )的大小与摆头锥角不匹配和摆辗中心的偏移对摆动辗压成形件高度尺寸精度的影响 ,探讨了国内外摆辗机的合理应用范围 ,指出只有摆角较小的摆辗机才宜于净形与近似净形加工摆动辗压成形件 The working principle and swing movement of the swinging forming process are briefly introduced. The misalignment between swinging tilt angle (ie swinging angle) and swinging cone angle and the deviation of the swinging center are analyzed in detail. The height dimension accuracy of the impact of domestic and foreign to explore the rational application of the swing machine, pointed out that only the smaller swing swing machine is appropriate net shape and approximate net shape swing forming rolling parts
