Effects of Process Parameters on Wall Distribution Homogeneity during Hot Power Backward Spinning for 7075 Cast Aluminium Alloy Tube

Abstract:

To obtain the effects of parameters on wall distribution homogeneity of 7075 cast aluminium alloy tube in hot power backward spinning accurately, a new method to accurately describe the wall-nonuniformity of the tube has been proposed. Combined with FE analysis, the change regularities of the wall-nonuniformity with the process parameters varying were obtained. The results show that wall-nonuniformity first increases slightly, and then decreases with the increase of preheating temperature. With roller feed rate increasing, wall-nonuniformity increases firstly, and then decreases. Furthermore, the wall-nonuniformity reaches a minimum value when the roller feed rate is 0.6mm/r. The wall-nonuniformity increases firstly, and then decreases with the increase of roller fillets radius, but the trend becomes weaker.
