介绍了应用冲压方法实现金属板料连接的新技术 ,并对板料冲压连接机理和连接处的金相组织进行了分析。板料冲压连接可分为 4个阶段 ,即板料初压入阶段、冲压连接圆点成形初期阶段、冲压连接圆点形成阶段、保压阶段。由于被连接的板料在冲压连接点处受挤压作用而产生压应力 ,提高了连接的抗疲劳强度。此外 ,对板料冲压连接的特点、应用范围及影响因素进行了论述。 The new technology of stamping method for metal sheet connection was introduced. The stamping connection mechanism of sheet metal and the microstructure of the joint were analyzed. Sheet metal stamping connection can be divided into four stages, the initial stage of the plate into the press, forming the initial stage of punching connection dot, punching connection dot formation stage, the pressure holding stage. As the connected sheet is pressed at the press-connection point to generate compressive stress, the fatigue strength of the connection is improved. In addition, the characteristics of stamping sheet metal, the scope of application and influencing factors were discussed.
