Abstract：

A die was designed for a direct tube single-ended shrinkage mouth part composed by aluminum alloy materials, which could meet continuous-time production and adapt to the characteristics of multi-position lathe. The die with subject disc structure was designed by analyzing forming feature of the considered parts and movement characteristics of multi-position lathes. Forming die finished rolling circularities by moving cams of the multi-position lathes. The right angle steering of circle tubes was realized by the ejection mechanism of the designed die. The subject disc turned around the oriented disc to make the shaping tool and shrinkage mouth forming die complete the direct tube truing and single-ended necking. In addition, some infrared detection equipment were installed in the outlet end of the die such that the die could realize automatic shutdown protection under unusual conditions. The turning results show that the operations of the designed die are normal, and the size of workpiece can meet the requirements of the drawings, as well as the working speed has reached intended purposes. All parts in the first continuous-time production can meet requirements of users.
