Clinching techniques are tools, components, systems and machines for the production of connections by the method of clinching. When clinching, the joining parts made of sheet metal and deformable materials are superimposed and fixed in the joining position. The joining tools consist of a joint stamp and a die or a flat anvil as the dolly. The term "toxen", which is used synonymously, refers to the patented methods of TOX Pressotechnik GmbH & Co. KG. Clinching is a joining process by means of forming, which allows non-detachable joining of sheets and other readily deformable materials without the use of connecting elements or additional materials. In the superimposed joining parts, local undercuts are formed by a linear or wobbling movement of a plunger against a female die or an anvil, which force-fit and form-fit the components. Clinching technology is used for the semi-automatic and fu...

Clinching is a joining process by means of forming, which allows non-detachable joining of sheets and other readily deformable materials without the use of connecting elements or additional materials. In the superimposed joining parts, local undercuts are formed by a linear or wobbling movement of a plunger against a female die or an anvil, which force-fit and form-fit the components. Clinching technology is used for the semi-automatic and fully automatic joining of sheet metal parts with high fatigue strength. It also allows connections of sheets with deformable materials such as plastics. The method also allows the joining of coated, oily or greasy metal sheets without pretreatment or follow-up treatment, without pre-punching and without connecting elements. An important area of application is the joining of car body parts. Clinching can partially replace spot welding. A further possible application is to secure components with adhesive bonds until the adhesive has hardened. A typical user industry is the automotive and automotive supplier industry.
