The clinching technology
Urban, Martin ; Žák, Ladislav (referee) ; Peterková, Eva (advisor)
This bachelor thesis contains a description of clinching technology. Most common failures of a clinch joint, which is either a fracture at the neck of the joint or a slip of the top layer, are shown. Furthermore, this work deals with the comparison of clinching with spot welding, which lists the advantages and disadvantages of clinching technology compared to spot welding technology. A list of several clinching methods is given. Follows an overview of clinching machines and tools. And at the end are indicated some examples of the use of clinching in practice.

A proposal of innovation technology for joining of components for specific purposes
Berka, Miroslav ; Jaroš, Aleš (referee) ; Píška, Miroslav (advisor)
The main goal of the diploma thesis is a proposal of alternative metal sheets joining technology which would replace the current technology of spot welding. Different variants have been proposed, and the one which suits the most, the technology of clinching, was compared to the existing one. The costs have been calculated and following results have been concluded: the return of investment of clinching press is about 2 years. In the case of handheld tongs it is 1 and a quarter of a year. Annual savings of clinching press are 234 485 Kč, and in the case of handheld tongs are 258 019 Kč.

Connecting methods used in automotive industry
Gregora, David ; Müller, Miroslav (advisor) ; Valášek, Petr (referee)
This bachelor thesis is focused on analyzing methods of joining sheets in the automotive industry. In the thesis are theoretically analyzed and described the various methods that are most often used for connecting plates in the automotive industry. It stated their principles, advantages and disadvantages. Selected methods are welding, soldering, adhesive bonding, riveting and clinching. This thesis works with methods that are used in the automotive industry for a long time, but also methods that are relatively new and brings to the production benefits that are mainly increasing productivity and lowering production costs and the weight of the entire body.
