摘要

新型高性能金属材料的应用日益广泛，对钢板连接问题提出了新的挑战。铆接技术已成为汽车行业绿色连接的常用手段。传统的锁接技术在汽车可见表面的应用受到锁接接头外凸性的限制。在夹紧过程中，压边架在控制料流方面的重要作用不容忽视。采用实验方法，研究了Al5052板材平铆工艺的连接质量。采用平底模具和铆钉在不同的压边架结构下形成连接。分析了几何参数、静强度、破坏模式和能量吸收。结果表明:采用锥形阶梯压边机形成的平铆合接头具有无压痕、吸能高、接头强度高等优点。平压铆工艺最好使用锥形台阶压边器。

Investigation of the flat clinch–rivet process with different blank holder structures

The increasing application of novel and high-performance metallic materials poses new challenges to the problem of joining sheets. Clinching technology has become the common means of green joining in the automotive industry. The application of conventional clinching to visible surfaces in automobiles is limited by the external protrusion of the clinched joint. It cannot be ignored the important role of the blank holder in controlling the material flow in the clinching process. In this study, the joint quality of Al5052 sheets for the flat clinch-rivet process was investigated by experimental methods. A flat bottom die and rivets were used to form joints under different blank holder structures. Geometric parameters, static strength, failure modes, and energy absorption were analyzed. The results indicate the flat clinch-riveted joints created by the conical stepped blank holder have the advantages of no indentation, high energy absorption, and high joint strength. The flat clinch-rivet process should preferably use a conical stepped blank holder.

期刊介绍： Manufacturing industries throughout the world are changing very rapidly. New concepts and methods are being developed and exploited to enable efficient and effective manufacturing. Existing manufacturing processes are being improved to meet the requirements of lean and agile manufacturing. The aim of the Journal of Engineering Manufacture is to provide a focus for these developments in engineering manufacture by publishing original papers and review papers covering technological and scientific research, developments and management implementation in manufacturing. This journal is also peer reviewed. Contributions are welcomed in the broad areas of manufacturing processes, manufacturing technology and factory automation, digital manufacturing, design and manufacturing systems including management relevant to engineering manufacture. Of particular interest at the present time would be papers concerned with digital manufacturing, metrology enabled manufacturing, smart factory, additive manufacturing and composites as well as specialist manufacturing fields like nanotechnology, sustainable & clean manufacturing and bio-manufacturing. Articles may be Research Papers, Reviews, Technical Notes, or Short Communications.
