    Abstract
  • Aiming at the prominent problem of low material utilization and low production efficiency in the forming process of CuNi90/10 sock welding tee, a new hot forming technology is presented, and a thermal mechanical FEM model is established based on the software Deform-3D, the effects of punch shape, feeding speed, initial temperature of workpiece and friction coefficient on horizontal load is comparatively analyzed. Results show that the quality of cylindrical convex surface of punch is the best, the optimal feeding speed is 40 mm/s, and the suitable initial temperature is 950℃~1 000℃. Besides, the smaller the friction coefficient is, the better the forming quality.
