摘要
介绍了传统大型扁管铝型材挤压模过早失效的原因。详细分析了传统大型扁管铝型材挤压模的结构特点。通过实际例子,提出了一种新的模具结构,阐述了这种模具结构的组成要素,说明了主要结构参数的选择,描述了新模具结构的特点,这种结构的金属分流方式可以大大降低挤压力。通过对新旧模具结构的使用结果对比,表明新的模具结构具有明显优势,能大大提高模具的寿命,值得推广。
As for the traditional large flat tube die for aluminum alloy extrusion,the causes for its premature failure were introduced and its structure characteristics were analyzed. A new type of hollow die structure was presented after practical examples investigated. Then the statement covered the components,parameter selection and characteristics of the new structure. Its metal feeding type can greatly reduce the extrusion force. Compared with the traditional die structure,the new one is far more advanced,leads to much longer die life, and is worth promoting as a result.
