一、概述铆钉联接是一种不可拆卸联接。由于焊接技术的发展，在许多场合逐步替代了铆接，但铆接联接在可靠性与受热影响方面比焊接容易保证与控制，特别在车辆、容器、桥梁、船舶、建筑等生产部门仍被广泛应用。铆接生产采用液压在冷态下挤压成形工艺比传统用风动铆接具有多方 First, an overview Rivet connection is a non-removable connection. Due to the development of welding technology, riveting has been gradually replaced in many occasions. However, the riveting connection is easier to guarantee and control than the welding in terms of reliability and thermal effects. It is still widely used in production departments such as vehicles, containers, bridges, ships and buildings. Riveting production using hydraulic pressure in the cold forming process than the traditional riveting with a multi-purpose
