abstract = {Bow-collapse is a kind of geometric defect in gear cold roll-beating process. In order to effectively control the bow-collapse and improve the material utilization, the paper calculates the cross-section radius of the blank according to the principle of volume invariance of metal plastic deformation, and then carries out the FE simulation of cold roll-beating process by using the method of cyclic beating of the adjacent tooth spaces and intermittent feeding of the blank. The flow state of metal particles is investigated, revealing that the movement of metal particles along the axial direction of the blank is the main reason for the formation of bow-collapse. The method for correcting the cross-section radius of the blank and thus controlling the bow-collapse is proposed, and the loss coefficient K is proposed to characterize the state of metal particles loss in a spatial region of infinitesimal thickness on the cross-section. The analytical equation for calculating the corrected value of the cross-section radius is derived and the corrected value is calculated. Cold roll-beating FE simulation is carried out on the modified blank, and the simulation results show that the bow-collapse is effectively controlled, and the loss coefficient K correctly reflects the loss state of metal particles on the cross-section.

Bow-collapse is a kind of geometric defect in gear cold roll-beating process. In order to effectively control the bow-collapse and improve the material utilization, the paper calculates the cross-section radius of the blank according to the principle of volume invariance of metal plastic deformation, and then carries out the FE simulation of cold roll-beating process by using the method of cyclic beating of the adjacent tooth spaces and intermittent feeding of the blank. The flow state of metal particles is investigated, revealing that the movement of metal particles along the axial direction of the blank is the main reason for the formation of bow-collapse. The method for correcting the cross-section radius of the blank and thus controlling the bow-collapse is proposed, and the loss coefficient K is proposed to characterize the state of metal particles loss in a spatial region of infinitesimal thickness on the cross-section. The analytical equation for calculating the corrected value of the cross-section radius is derived and the corrected value is calculated. Cold roll-beating FE simulation is carried out on the modified blank, and the simulation results show that the bow-collapse is effectively controlled, and the loss coefficient K correctly reflects the loss state of metal particles on the cross-section. The simulation results also show that after cold roll-beating, the gear teeth with standard face width and tooth depth can be obtained after two processes of turning end faces and turning the tip circle. The bow-collapse control method proposed in this paper effectively improves the material utilization.
