Optimization of Molding Process Parameters for Steel Ball Billet
Such evaluation standards as plumpness, roundness, force of cold upsetting, and the volume are made through the research on cold upsetting steel ball. Through a designed orthogonal test and the DEFORM simulation analysis, the process of ball billet is explained reasonably after primary selection and screening. Thus through comparison, it is seen that the original process is improved to a large degree.
