Abstract：

The stability of the feed in wheel groove at the beginning of the feeding stage was analyzed.The convexity in the round wheel groove was critical for founding a steady copper continuous extrusion through the theoretical calculation and simulation analysis.Some new shapes of wheel grooves based on the round rod were brought forward.FEM simulations were done on those wheel grooves for copper extending continuous extrusion.Then the influence of wheel groove on the metal formability,the torque of the extrusion wheel and the uniformity of the metal flow were analyzed in copper extending extrusion.At last,the conclusion is drawn that the flared wheel groove with convexity is the optimum wheel groove for the extending extrusion.
