Research on an analytical method for the forming force of external spline cold roll-beating
Qun Ma, Xiangwei Zhang
Izvirni znanstveni članek
Oznake: discrete analytical method;cold roll-beating;forming force;deformation zone;radial force;
To determine the force and energy parameters of cold roll-beating of external splines, the characteristics of the deformation zone in cold roll-beating are analysed. The geometric dimensions and position of the deformation zone change with the movement of the roller, the contact arc, and the reducti ...

Simulation research on the control method of bow-collapse in gear cold roll-beating
Qun Ma, Li Cha, Xiangwei Zhang
Izvirni znanstveni članek
Oznake: cold roll-beating;bow-collapse;FE simulation;loss coefficient;cross-section radius;
Bow-collapse is a type of geometric defect in the gear cold roll-beating process. In order to effectively control bow-collapse and improve material utilization, this paper calculates the cross-section radius of the blank according to the volume invariance principle of metal plastic deformation, and ...
