A aluminum alloy extrusion die structure on the large flat tube

摘要

The factors on premature failure of the traditional extrusion die for the big flat tube profiles were introduced. And the characteristics of the conventional structure was analyzed. Through an actual sample, a new type of hollow die structure for these profiles was presented. The composition elements of the new die structure were described. The selection of the main structural parameters was explained, and the characteristics of this new structure was described. In particular, the metal feeding way of this structure can greatly reduce the extrusion force. The new die structure has obvious advantages, which could greatly improve the die life. This is a type of die structure which is worth promoting.
