Abstract:
The article introduced the die digital design, optimization and production quality forecast of extrusion, and the processes of die digital manufacture. The authors pointed out that, the aims of the digital design of extrusion die were providing geometry and topology information of the die, as well as the process information of extrusion practice. The core technologies of the digital design were digital modeling and digital simulation. Digital simulation was applied in analyzing metal flowing behaviors, die optimization, and production quality forecast of extrusion. Using virtual extrusion based on digital simulation was an effective way to achieve 搘ithout die test?of extrusion die, and also was an important platform for developing new design ideas and methods. The feature of digital manufacture of extrusion die was the wide application of CNC processing, heat treatment and surface treatment. Improving the manufacture level of extrusion dies with complicate and multi-orifice structure through combining CAD, CAM and CAE effectively, was the key development direction of the extrusion die digital manufacture industry at the current stage of our country
