Abstract

A novel clinching process design to join thin metal sheets and foils is proposed. In this process a small cup is first stretched out of the sheet plane. A shape interlock between the two sheets is then created by a movement of the die and blank holder in the sheet plane lateral to the cup wall. Such an approach makes the undesired upsetting of the cup bottom redundant, which promises less energy consumption and a longer tool life when compared to conventional clinching processes. The process principle and its finite element analysis for austenitic steel sheets as well as deepdrawing steel sheets (both 0.3 mm thick) are presented. The numerical results suggest feasibility of the proposed design to produce a good shape interlock between two thin sheets.
