摘　　要：本文介绍了蛇形管生产线上数控小R顶镦弯管模Φ42 R60/R115工艺试验,针对使用常规弯管模设计型面后出现的弯头质量问题,对预变形设计进行了工艺改进,对其左右滑槽模、上模、中模、下模等的主要型面预变形进行了修正,有效提高了蛇形管弯头的质量,在锅炉生产中得到良好的应用。This article introduces the processing experiment of numerical control of small radius up- setting die on serpentine tube production line. Focused on elbow quality problem caused by using conventional bending die design profile, the design of the pre-deformation has been improved by modifying the pre-deformation of main profiles such as left and right chute die, upper die, middle die and bottom die ect. Effectively improved the quality of the serpentine elbow, acquired good use in boiler production.
