Joining of Cold-Reduced Carbon Steel Sheets by Impulsive Riveting method

Abstract

In this paper, a new riveting method of which the joining of the sheets was possible without drilling of the sheets as well as the easy disjoining of the joint also was possible was proposed. And the riveting method was applied to the joining of cold-reduced carbon steel sheets. The joining was carried out by the following process. A rivet set on the sheets was stuck into the sheets using a high-speed weight. Then the axis of the struck rivet penetrated the sheets. Finally, the rivet axis which went through the sheets was jointed with a rivet holder set under the sheets and the sheets were tightened by the head of the rivet and the rivet holder. For the joint produced by the proposed riveting method, the distortion and plastic deformation of the joined plates, static and cyclic joint strength were examined by comparison with those of the joint produced by ta conventtional riveting method such as caulking. From the resutls, it was found that the joint produced by the impulsive riveting method was superior to the joint produced by caulking, in addition, the joint produced by the impulsive riveting method was able to be disjoined easily.
