Shaping Parameter Control of High-Speed Cold Roll-Beating Based on Simulation and Regression Analysis

Abstract:

High-speed cold roll-beating is a near-net shaping technology in which with the characteristic of metal plastic forming used, revolving roller with high speed is applied to roll and beat the blank shaft, then force mental to flow and form a component profile. In the forming process, matching between the process parameters and the part profile is key to implement and apply the technology. In this paper, the FEM model of the lead screw cold roll-beating forming is built, the ABAQUS software is used to simulate the forming process. Based on the simulation results, the orthogonal test is designed, influence of process parameters on groove depth and bulging height of cold roll-beating process are studied; multivariate regression models of maximum bulging height and groove depth relative to the process parameters are established, and the effectiveness of the models are verified, which is of important guiding significances for forming accurate profile of lead screw by controlling process parameters.
