摘要
为了解决汽车平行流多孔管连续挤压过程中模具孔针断裂和产品焊合质量不好的问题,采用LLJ300铝连续挤压机,研制成功了具有凸模侧面加强筋、预成型模和具有分流通道的汽车空调平行流多孔管连续模具和腔体,有效解决了平行流多孔管连续挤压过程中存在的技术难题,并已应用于工业化生产。
In order to resolve the problems of the die pin fracture and improve product seaming during the manufacture of aluminum alloy micro multi void tubes, on the LLJ300 continuous extrusion machine, the die with strengthen rib in flank of mandrels, preforming die and uniformity metal flowing hole are designed. At present, the technology has been used in producing micro multi void tubes.
