摘　　要：提出了一种镦胀成形变径管的方法,以解决变径管镦筋成形宽度较窄、胀形减薄严重的问题。分别对镦筋成形和镦胀成形进行了实验对比,对镦胀成形模拟分析结果与实际成形壁厚分别进行了对比。结果表明,镦胀工艺集镦筋镦粗效应和胀形扩径效应于一体,可实现变径管低变薄成形。In this paper,a method of upsetting tube is proposed to solve the problems of narrow forming width and serious thinning of upsetting bar forming.The wall thickness of the upsetting bar forming is compared with the actual upsetting bar forming.The results show that the upsetting process can realize the low and thin forming of the reducing tube by integrating the upsetting effect of the upsetting bar and the expanding effect.

关 键 词：镦胀成形 镦筋成形 变径管
