The aim of this paper is to determine whether the train axle cross wedge rolling(CWR) using square billet as blank is available or not. Based on numerical simulation software DEFORM-3D, we built the finite element model. And the whole forming process was simulated successfully. The stress and strain distributions of workpiece in the process were analyzed. Comparative study of warm and hot cross-wedge rolling Apr 28, 2017 · Numerical simulation and experimental trials were conducted to make a detailed comparison of warm and hot cross-wedge rolling. Forming quality, microstructure, and mechanical properties of the rolled rods were investigated using scanning
Jan 01, 2018 · To verify this rolling method, we performed numerical analysis simulating a case of forming a single (central) necking with a 10 mm diameter made on a billet (with a diameter of 32 and a length of 46 mm) by two wedges that are moved in the opposite directions with a Numerical Analysis of the Cross-Wedge Rolling Process by Numerical Analysis of the Cross-Wedge Rolling Process by Means of Three Tools of Stepped Shafts From Aluminum Alloy 7075 Autorzy. Bartnicki, J., At the same time, the force parameters, which play a crucial role in the designed experiment, were analyzed. PL. Numerical Modeling of Cross-Wedge Rolling of Hollowed Numerical Modeling of Cross - Wedge Rolling of Hollowed Shafts and Mechanical Department, Lublin University of Technology, Nadbystrzycka 36, 20-618 Lublin, Poland Abstract. In this article, the results of numerical calculations and experimental work of the cross-wedge rolling (CWR)
The numerical analysis enabled the determination of changes in shape of the workpiece, strain and temperature distributions, as well as variations in the forces acting on the tool. The numerical results demonstrate that personal computers can today be used to model even most difficult cases of the CWR process, where complex shapes of tools and thermal phenomena occurring during forming are taken Prediction of Crack Formation for Cross Wedge Rolling of The article presents the issue of material fracture during the process of cross-wedge rolling (CWR). The object of the research was the process of forming a harrow tooth preform. In the conducted analysis nine damage criteria were applied. The critical value of damage was determined with a new calibrating test, basing on rotational compression of a sample in a channel. Simulation Analysis of Cross Wedge Rolling Hollow Parts Cross wedge rolling hollow shafts with a mandrel has attracted much attention in the recent years because of the demand for light components. Finite element method was used to simulate the rolling process of hollow part and validated by experiment. By tracking strain change of the typical points and analyzing the strain contour maps of cross-section at four typical moments, the cause of cross
Jun 18, 2021 · The precision forming of inner hole is one of technological bottlenecks in Cross-wedge Rolling (CWR) of hollow shaft with mandrel. The inner diameters show signs of characteristic fluctuation despite under the control of mandrel. The uniformity of inner diameter was investigated by finite element simulation and experiments in this study.
