Abstract：

For the defects of riveting and spot welding connection technologies, the cold stamping connection technology was put forward by domestic scholars. According to the principle, a new joint method and the corresponding forming law were carried out. The results show that some changes take place in the thickness and the width of connecting section and they are deeply analyzed. At the same time, the forming load experiences the characteristic stages. The curve increases slowly at first, then rises sharply. When the load reaches a certain degree, the curve continues to rise slowly until the load keeps constant. According to the changes of the load curve, the forming load is divided into four stages. The thickness distribution of joint appears to increase first and then decrease, and the curve presents an approximately symmetric distribution. Through the analysis between the simulation and the experimental results, the width of joint increases obviously, and they agree with each other well.
