Sheet metal parts are made through processes such as filament power winding, laser cutting, heavy-duty machining, metal bonding, metal drawing, plasma cutting, precision welding, roll forming, sheet metal bending, die forging, and waterjet cutting. Rivetless riveting technology is a rapidly developing mechanical connection technology for thin sheet materials. This process joins two pieces of metal together without the need for rivets or pre-drilling. It utilizes the principle of stamping, with punches and dies on the top and bottom of the two materials respectively. The upper material is pressed into the lower material, resulting in a tight and secure connection. Compared to traditional processes, it offers advantages such as low energy consumption, no need for auxiliary materials, high-quality connection points, simple process without pre-drilling, and high work efficiency.

[0024] Specifically, a horizontal plate 18 is provided below the riveting joint 7. The horizontal plate 18 is fixedly connected to the upper surface of the base 1. A second sliding groove 21 is provided inside the horizontal plate 18. A second slider 20 is slidably arranged inside the second sliding groove 21. An installation frame 17 is slidably connected to the top surface of the horizontal plate 18, so that the installation frame 17 can slide on the top of the horizontal plate, which can flexibly adjust the horizontal riveting processing position of the sheet metal parts and improve the accuracy of the riveting processing. The installation frame 17 is connected to the base 1 through the horizontal plate 18 below it. A support rod 24 is fixedly connected to one side of the installation frame 17. A push rod 23 is fixedly connected to one end of the support rod 24. A cylinder 14 is fixedly connected to one end of the push rod 23.
