Mechanical joining of dissimilar materials by shear clinching processes without pre-punching (shear clinching)



Project Status: Active

Members


Subproject DFG Priority program 1640

In cooperation with LWF Paderborn

Shear-clinching is an innovative technology for joining by forming of dissimilar materials without additional fasteners. A form and force fitting joint is created by the indirect cutting of the die-sided sheet material with low ductility and the lateral extrusion of the punch-sided material. The objective of the research, which is conducted in cooperation with the LWF in Paderborn, is the further development of the technology. Since the shearing of the die-sided sheet and the extrusion of the punch-sided material both lead to high process forces, the tool loads during shear-clinching and the wear behaviour of the active tool elements are analysed within the third phase of the project, which is part of the priority program 1640. This enables the design of tools with low wear and the improvement of the process stability.
