Özet

© 2022, Emerald Publishing Limited.Purpose: The purpose of this study is to investigate how the sloping head fault in solid riveting affects the strength of the joint and to develop an efficient system for the solution of the problem. Design/methodology/approach: For rivet joints, 1.2-mm thick 2024-T3 plates were used. AD 2117 T4 solid rivets with a diameter of 3.2 mm were chosen for the joints. A new riveting mechanism has been created unmatched in the literature for solid rivets. In the riveting process, the bucking bar surface is positioned at a right angle to the riveting process axis. Alternative 5°, 10° and 15° fault angles were obtained. During the riveting process, a total of eight different test samples were produced, four for each of the tension-shear and cross-tension joints, by making 0°, 5°, 10° and 15° angles to the bucking bar. To determine the mechanical properties of the prepared samples, cross-tensile and linear tensile-shear tests were performed on a universal tensile testing machine. Special apparatus has been designed and produced for cross-tensile tests. Findings: As a result of the tensile-shear tests, the decrease in the joint at 15° was 25% compared to the joint at 0°. There is no systematic change in elongation. As a result of the cross-tensile tests, there was a decrease in the cross-tensile force toward the sample with an error of 15°. Compared to the 0° joint, this decrease was approximately 14.5% in the 10° joint, while the decrease in the 15° faulty joint was 25.8%. It has been understood that riveting with an angle of 0° affects the strength very much. Originality/value: A new riveting mechanism has been created unmatched in the literature for solid rivets. Experimentally, it has been shown that forged rivets can be made very economically and properly. It has been experimentally proven how much the rivet head shape formed in the wrong forged rivet application changes the result.
