Clinching Process In Sheet Metal

Steel and stainless steel aluminium and or non ferrous materials.

Clinching process in sheet metal. With the clinching process sheet metals of different thicknesses or other materials even with adhesives or other intermediate layers are joined in a cold forming process. To perform clinching a metalworking company secures and aligns the sheet metal between the punch and die. Clinching or press joining is a bulk sheet metal forming process aimed at joining thin metal sheet without additional components using special tools to plastically form an interlock between two or more sheets. It is based on the plastic deformation of the sheet metal you need to join that is possible through the interaction between a punch and a die without the supplement of added material.

The tox clinch procedure is a proven substitute for welding screwing riveting. While the sheet metal may be preheated the process is typically performed at room temperature. Once in place the punch is engaged thereby pressing down on the sheet metal with low to medium force. Also known as press joining clinching refers to the use of a punch and die set to press or clinch two or more pieces of sheet metal together.

Clinching also known as press joining is a high speed mechanical fastening technique for point joining of sheet metal components. It uses the solid die cavity patented by tox pressotechnik. The clinching process is a method of joining sheet metal by localised cold forming of the materials. Clinching is characterized by a series of advantages over competitive technologies.

The process is generally performed at room temperature but in some special cases the sheets can be pre heated to improve the material ductility and thereby avoid the formation of cracks during the process. With this joining technique metal parts are deformed locally without the use of any consumables. In industrial applications clinching is being applied for single sheet thicknesses of 0 1 mm up to a total layer thickness of 12 mm 47 and up to 800 n mm 2 5 7 lbf in2. The clinching technique is an innovative process for the mechanical cold junction of sheet metal.
