摘要:
介绍了半空心铝型材挤压模的研究现状,分析了针对半空心铝型材的5种模具结构,包括整体式平模、镶嵌式分流模、遮盖式分流模、吊挂式分流模和切割式分流模。提出了一种新的半空心铝型材挤压的保护导流式分流模具结构,结合具体实例,介绍了这种保护导流式挤压模结构,详细分析了这种结构的组成和参数选择,主要包括分流孔的设计、挤压机能力的选择、分流桥的结构、应力间隙和工作带的选择,并给出了模具强度校核方法。根据挤压结果,与传统平面模、切割式分流模进行了对比。结果表明,这种新型模具结构简单、便于加工,可显著提高模具强度和寿命。
 

 The research status of extrusion die on the semi-hollow Al-profiles was described, and its five die structures were analyzed including the integral flat die, the mosaic porthole die, the 

covering porthole die, the porthole die with a suspended cantilever and the cutting porthole die. Then, a new protective flow-guided porthole die structure for the semi-hollow Al-profiles was presented by a practical example, and the die structure named protective flow-guided extrusion die was introduced. Furthermore, the composition of structure and selection of parameters were analyzed in detail, mainly including the design of portholes, selection of extrusion machine, structure of  prothole bridge, selection of stress gap and bearing, and the method about how to check die strength was introduced. According to the extrusion result, the structures of traditional flat die and mosaic porthale die were compared to  the new one. The results show that the new structure is simpler and easier to process which can improve the strength and prolong the life of die.
