“…Heat was introduced for the clinched joint when joining materials with low ductility such as the connection of magnesium material sheets. The results showed that the heating time varies with the die shape and that less heating time is needed with the dieless clinching process [38,39] An experimental study was conducted to inspect the quality of the clinching joint of high-strength thin steel H320LA visually, and by examining the strength of the connection of the two sheets [20,21]. To ensure the integrity and the quality of the clinched point, the bottom thickness of the two sheets after forming the joint was measured.…”

Clinching is a method for mechanically joining sheet metal of different thickness and properties in which the two plates to be joined undergo plastic deformation. The clinching process is established by connection or joining using simple tools: a punch and a die. This method has different characteristics compared to thermal joining methods, such as spot welding, including low purchase and operating costs, little preparatory work, safe and environmentally friendly, interesting mechanical properties, reproducibility, and durability. In this article, a brief review of traditional joining methods for dissimilar materials and the clinching process are illustrated in greater detail. In addition, the article looks to guide researchers for future work by identifying weaknesses of the current processes as well as potential for valuable contributions in the field of clinching.

The tools of the mechanical connection process were assumed to be rigid during the simulation.…”

Clinching is a mechanical joining method using a simple toolset consisting of a punch, a die, and a blank holder. The shapes of these tools are the most important parameters that control the final geometry of the clinch joints and consequently the strength and quality of the latter. In order to save time and cost, these geometric parameters could be optimized by the use of finite element simulation. This paper reviews the published research related to the finite element modeling of the clinching process. In this study, a critical review of the latter had been carried out from different perspectives. The findings about difficulties facing the simulations of different clinching processes, the optimization of the process parameters, and the strength, joinability, and the quality of the joint were highlighted. In addition, future development, investigation, and more research are still needed to minimize problems and expenses in the industrial practical application of clinching.

“…The clinching joining technology (CL) is commonly used in the automotive industry during the assembly processes of sheet metal thin-walled constructions [1,2]. The joint formation is made by a cold pressing process on a very small area and such parameters of the process as tools geometry and pressing force determine the interlock quality ( Fig.…”
