Cross wedge rolling is an important part of advanced forming manufacturing, which makes up for the defects of traditional forging process technology. It is one of the new technologies that are studied and actively adopted internationally, and is listed as one of the new technologies that are promoted by the state. It fully meets the requirements of building China into a resource-saving and environment-friendly society. It is the advanced technology of ladder shaft billet widely promoted in forging works.
Simple process, less equipment required, high production efficiency.
Forgings factory only needs one mill to produce shaft forgings using cross wedge rolling technology, which can roll two pieces at a time. And with the common turning process, need many times clamping, knife for many times, need many lathes, many tools, many times clamping, production is more troublesome. With ordinary forging, the blank with skin can be forged by drawing, pre-forging and forming. Compared with the three technological methods of turning, forging and cross wedge rolling, the shaft efficiency of cross wedge rolling is much higher than that of turning and forging respectively.
