- 摘要:
- 针对常规成型工艺压制钢板制异径接头时存在的不足,提出了一种成型新工艺。该工艺改变了管坯、模具的结构和管坯变形时的加热部位,降低了加热温度,简化了成型工艺和模具,提高了模具的通用性。文章介绍了该新工艺管坯的结构型式及成型方法、模具的结构、工艺流程、大端和小端分别一次成型方法、一次整体成型方法。
Because the traditional process of reducer forming by pressing steel plates has some shortcomings, a new forming process is brought forward, which changes the structure of pipe blank and die as well as the heating position and also decreases the heating temperature during pipe blank deformation. It simplifies the forming process and improves its applicability. This paper describes the structure and forming method of the pipe blank, structure of die, process flow, once-forming method of big end and small end of the reducer and integral once-forming method.2009,1(1): 71-74 收稿日期：2008-4-28分类号：TG306作者简介：张文生（1971-）, 男, 河北行唐人, 高级工程师, 1996 年毕业于江汉石油学院机械系机械制造与设计专业, 现从事机械制造与设计的技术工作。参考文献：
