In this embodiment, the riveting angle of the first riveted portion 233 is smaller than the riveting angle of the second riveted portion 243. During the secondary riveting process, punches with different riveting angles are used, and the flange shape at the riveted joint has a better fit with the first terminal strip 4 and the second terminal strip 5 than the punches with the same riveting angle. In addition, the secondary riveting completely releases the material stress at the riveted joint, and the protrusion 53 is completely attached to the first terminal strip 4 and will not rebound.

[0062] In this embodiment, several positioning pins 22 and several pressing blocks 25 move downward at the same time. Several positioning pins 22 pass through the first positioning hole 41 and the second positioning hole 42 to position the first terminal strip 4 and the second terminal strip 5, and at the same time, several pressing blocks 25 press the first terminal strip 4 and the second terminal strip 5 in the upper and lower directions. Then several first rivet pins 23 and several second rivet pins 24 press down. The angle α between the first riveting portion 233 and the terminal strip 6 is 90 degrees, pressing down the protruding portion 53 so that the protruding portion 53 is turned outward by 90 degrees. The first punch 234 passes through the first riveting hole 42 and the second riveting hole 52 and is inserted into the through hole 212 of the support block 211. The angle β between the second riveting portion 243 and the terminal strip 6 is 130 degrees, pressing down the protruding portion 53 so that the protruding portion 53 is completely attached to the first terminal strip 4.

[0063] As mentioned above, the riveting mechanism 2 completes the first pre-riveting and the second riveting through the first rivet pin 23 and the second rivet pin 24, and uses punches with different riveting angles. The flange shape at the riveted joint and the fit between the first terminal strip 4 and the second terminal strip 5 are better than those using punches with the same riveting angle. The first terminal strip 4 and the second terminal strip 5 form the terminal strip 6. The combination of the first terminal strip 4 and the second terminal strip 5 can reduce the cost of electroplating, and the process is simple and convenient for maintenance. Therefore, the strip riveting equipment 100 of the utility model has high precision, high riveting strength and high fit between the two strips.
