本文探讨了在分流组合模中使用浮动芯头套挤压铝管的有关工艺。结果表明,采用带有浮动芯头套的分流组合模挤压铝管,不仅比常规的固定芯头分流组合模具有明显的自动纠正管壁偏心效果,而且对于防止分流组合模的模芯根部断裂以及实现用分流组合模挤压铝管的模具结构轻型化、系列化均有较好的作用。
This paper discusses the use of floating core split in the shunt die extrusion aluminum tube related processes. The results show that the use of shunt die with floating core bushing to extrude the aluminum pipe not only has obvious self-correcting wall eccentricity effect than the conventional fixed core shunt die, but also has a significant effect on preventing the core break of split shunt die and Achieve with the diversion of modular extrusion die extrusion mold structure, series have a better effect.
