摘要
针对大直径弯管推弯成形中存在的耗电量太大、成本高、形状畸变、大型推弯机难于制作等问题 ,本文介绍了大直径厚壁弯管的步进成形模具、工艺装备和步进成形设备工作特点 。
The Paper introduces step-by-step forming dies and facilities for overcoming the problems,such as the large comsumtion of elecricity,high cost,deforming ete,which had been occurred in the coure of bending processes for pipe with large dvameter and thickness by using the push bending machines In addition,it is analyzed in this paper the realatiouship betweem force and work during step-by-step forming.
