Research on the Extrusion Process of belt with Notch Descrition
Northwest Institute of Mechanical and Electrical Engineering Xianyang Shaanxi China
The extrusion process of the belt is a process in which the belt and the inner bore of the barrel undergo complex contact and collision, and the rifling gradually penetrates the belt, so that the material of the belt continues to fail and destroy. It has high instantaneous, strong impact, high temperature, high-speed change. There is a big gap between the existing theory and the actual extrusion process, and it is urgent to carry out research work on this problem. This paper analyzes the basic characteristics of elastic and plastic deformation during the extrusion process of the belt, and establishes the Johnson-Cook constitutive model of the deformation, flow and failure process of the belt material. Explicit dynamic calculations are carried out in the process of belt extrusion, and the contact problems, deformation of the belt and material flow problems during the extrusion process of the belt are discussed in depth
