大方管铝型材挤压模结构的改进

Improvement of Extrusion Die for Big Square Tube Profiles of Al-alloy

文章介绍了传统大方管铝型材挤压模过早失效的原因,详细分析了传统大方管挤压模的结构特点,提出了一种新的模具结构,并阐述了这种新模具结构的组成要素,说明了有关主要结构参数的选择,描述了这种新结构的优点。通过对新旧模具结构的使用结果对比,表明了这种新的模具结构是有效的,具有明显优势,能大大提高模具寿命,是一种值得推广的模具结构。

In this paper , the factors on premature failure of the traditional extrusion die for introduced, the structure characteristics of the conventional big square tubeare analyzed in detapresented and also the composition elements, selection of main structure parameters,advantages. According to thecomparison of conventional and new die structure, it shows that the new structure has obvious improve the die life, and it is worth of being generalized.
