摘要

本文提出了一种用于板料零件搭接的新型双平头铆接工艺。该工艺包括冲孔、锻造和剃削，以产生精确几何形状的沉孔，然后将圆柱形铆钉压缩到两个重叠的薄板零件的孔中，以形成封闭的机械联锁。实验和数值分析考察了主要工艺参数对联锁质量的影响以及所需的成形力和破坏力。这项研究是连接技术的一个进步，提供了一种简单的替代焊接、粘合和机械连接的方法，可以无缝集成到多阶段成形工具中。

Advanced double-flush riveting for multistage forming tools

This paper presents a novel double-flush riveting process for creating lap joints in sheet metal parts. The process involves punching, forging, and shaving to produce countersunk holes with precise geometry, followed by compression of cylindrical rivets into the holes of two overlapped sheet parts to create form-closed mechanical interlocks. Experimental and numerical analyses examine the influence of the primary process parameters on interlock quality and required forming and destructive forces. The investigation is a step forward in joining technology by offering a simple alternative to welding, bonding, and mechanical joining, with seamless integration into multistage forming tools.
