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