Influence of tool parameters on tool wear in two-roll cross-wedge rolling

Abstract

A simulation model for two-wedge two-roll cross-wedge rolling was presented by using three-dimensional rigid plastic finite element method. Based on the simulation results, the influence of three tool parameters—the forming angle α, the spreading angle β, and the area reduction Ψ on tool wear—is ascertained and discussed. The study results indicate that the tool wear depth increases with larger α, β, and Ψ. Simultaneously, tool wear can be improved under the condition of α = 28°, β = 8°, Ψ1 = 48.6 %, and Ψ2 = 53.3 %. Subsequently, blank forming for the engine connect rod was produced in the factory and statistical data from the factory manifests the feasibility of study results.
