Abstract
In order to research the ploughing extrusion angle influence on cutting performance and realize the virtual design and manufacture of ploughing-extrusion forming cutter, the plough-extrusion forming process of wick micro-groove structure was simulated by DEFORM-3D software. The micro-copper tube with diameter of 6 mm was simplified to 0.4 mm thick copper plate in this paper. In the simulation process, only the single parameter of tool extrusion angle was changed (45°, 60°, and 90°). The structure, stress and strain distributions of copper plate fins formed by three kinds of extrusion angle cutters were analyzed. It is concluded that the plough-extrusion cutting performance of 60 degree extrusion angle cutter is the best.
