Abstract

Metal forming technology has been applied to effective production of metallic components in various fields. One of the newer metal forming techniques is so called „joining by forming“. With this method two or more separate parts are joined together using plastic deformation. Self-piercing riveting, clinching and coin and medal production are some of the joining by forming operations, which have been successfully applied in industry. The present study is bound to a process of joining of two bimetallic axisymmetric components from various materials by upsetting bimetallic components in a closed die. The external component is a ring and the central part is a cylinder – like element. By upsetting those two elements in closed die, inseparable workpiece has been obtained. Therefore, two different cases (geometries) have been investigated. In the first case the simple ring and profiled inner cylinder are combined while in the second case vice versa combination is applied. Also, forming load, material flow and filling of joint section were analyzed. The process has been investigated experimentally. In short, current investigation has yielded considerable insight into the process of joining two metallic components.
