Abstract

Cold roll-beating forming is a metal bulk forming technology at room temperature, which is mainly used in the forming of external teeth. The influences of forming parameters on forming force and metal deformation in cold roll-beating forming are studied. The key processing parameters are selected according to the principle and processing characteristics of cold roll-beating forming. The forming force and metal deformation in the forming process are obtained by experiment and simulation of tooth groove forming of bulk metal. The changing characteristics of forming force under different roll-beating ways are explained, and the deformation characteristics of metal and the causes of forming defects in cold rolling forming are expounded. The influences of different process parameters on the forming force and forming quality of tooth groove are discussed. The results show that for up-beating the forming force is small but unstable, and the different roll-beating ways have little influence on the forming accuracy;the roll-beating density can be suitably increased to reduce the forming force and improve the forming accuracy; and the spindle speed is increased to enlarge the forming force and induce the occurrence of forming defects under the condition of same roll-beating density.
