“…A comparison studies between round and square clinching tools for high-strength sheet metals have been conducted by Varis [6]. Pedreschi and Sinha [7] conducted an experimental study of cold formed steel trusses using mechanical clinching and found that the number of clinches has a marked influence on the strength, deformation and failure mode of the trusses. In Oudjene et al's study [8], a response surface methodology (RSM), based on Moving Least-Square (MLS) approximation and adaptive moving region of interest, is presented for shape optimization of clinching tools.…”

The aim of this study is to predict the torsional free vibration characteristics of single lap-jointed cantilevered hybrid clinched joints. The focus of the analysis is to reveal the influence on the natural frequencies, natural frequency ratios and mode shapes of single lap-jointed cantilevered hybrid clinched joints caused by variations in the material properties of the structural adhesives. It is shown that the torsional natural frequencies of single lap jointed cantilevered hybrid clinched joints increase significantly as the Young's modulus of the adhesive increase, but only slight changes are encountered for variations of Poisson's ratio. The mode shapes show that there are different deformations in the jointed section of the odd and even modes.

“…The clinching process has been implemented on light-weight structures with high production rates, such as automobiles, electronics, and household appliances. For instance, clinching is widely applied in the automobile industry since the sheets of material are generally not pierced for vehicle body applications [6,7]. It has been found that the joint strength depends on various geometrical process parameters [8].…”

Rigid-plastic and elastic-plastic finite element analysis on the clinching joint process of thin metal sheets

et al. 2010

This article describes the joining of thin metal sheets by a single stroke clinching process. Elastic-plastic and rigid-plastic finite element analysis were applied by employing Coulomb friction and constant shear friction in order to investigate the behavior of the clinch joint formation process. Four process variables, such as die diameter, die depth, groove width, and groove corner radius were selected to investigate the parametric effect on the clinch joint. The strength of clinch joints were evaluated by examining the separation strengths, such as peel strength and tensile shear strength, respectively. A failure diagram was constructed that summarizes the analysis results. The simulation results showed that die diameter and depth were the most decisive parameters for controlling the quality of the clinch joint, while the bottom's thickness was the most important evaluation parameter to determine the separation strengths.

“…Clinching has been used on an industrial scale for over 30 years and has been successfully applied to a wide variety of materials and material combinations. Clinching is commonly utilized in car body production [3], building components [4], even in electrical industries. It is a cold joining process of sheets by local hemming with a punch and die.…”

Abstract:A clinching method that uses a simple toolset consisting of a punch and a die, is utilized for joining lightweight materials. This paper is aimed at investigating the wear of the die cavity of a clinching tool. A clinching tool with a specially shaped cavity was used for joining thin hot-dip galvanized steel sheets. Various types of physical vapour deposition (PVD) coatings such as ZrN, CrN and TiCN were deposited on the shaped surface of the die using Lateral Rotating Arc-Cathodes technology. Hot-dip galvanized steel sheets were used for testing the clinching tool. The material properties of PVD coatings that were deposited on the shaped part of the clinching die were evaluated. Finite Element Analysis was used to localize the area of the shaped part of the die and the part of surface area of the cylindrical die cavity of ϕ 5.0 mm, in which high contact pressure values were predicted. The prediction of the start of the wear cycle was verified experimentally by the clinching of 300 samples of hot-dip galvanized steel sheets. Unlike the CrN and ZrN coatings, the TiCN coating remained intact on the entire surface of the die.
