Effects of Die Tooth Profile on Forming Helical Tooth Shaft in Cross Wedge Rolling

Abstract:

The study on forming helical tooth shaft processes in cross wedge rolling can contribute to the advantages of material-saving and efficient. Die tooth profile is an important process parameter of cross wedge rolling helical tooth shaft. Three kinds of forming process of die helical teeth were simulated by DEFORM-3D finite element analysis software to analyze three different die helical tooth. According to the tooth forming characteristics, the effects of three kinds of die tooth profile on forming of a polled piece were analyzed. When rolling a polled piece using the die with the same addendum width, it is convenient for die processing and the effect of polled piece forming is better; when using the die with the narrow front and gradually wider rear, the defects of uneven tooth bottom and larger pitch may happen. The rolling experiment was made by using the die with the same width at the tooth bottom. The results are in good agreement with the simulation. Therefore, we should use the die with unchanged addendum width, tooth height and the sidewall proportional increased when designing the die.
