THE WAY OF MANUFACTURING PARTS LIKE STEPPED SHAFTS BY MEANS OF CROSS-WEDGE ROLLING

摘要

One method of moulding of the shaft member being made of cross-wedge rolling is arranged to reduce the driving force of an actuator of the cumulative fatigue resistance by an axis and the appearance possibility of a kind of cavities open part successively decreased. One method of moulding of the shaft member being made of cross-wedge rolling includes a step, for reallocating a kind of metal according to by a work piece of two or more wedge tools and an axis (1) for a step, it is used to reduce energy consumption by the driving force one or more wedge tool for reducing by a steel rolling mill, reciprocal in one jiao of 0 degree~90 degree.
