Automatic riveting is a kind of cold connection technology used to connect two or more kinds of metal sheet materials. Its basic principle is to apply the characteristic bolt according to the hydraulic cylinder or servo motor motor to show the driving force, immediately press into the plate to be riveted, and the plate to be riveted will produce plastic deformation with the bolt under the working pressure effect of the bolt, and then punch into the riveting die after forming, so as to produce a brand-new upgraded plate for stable connection. The riveting nose presses the riveted plate first, and the bolt is placed by the riveting rod through the hydraulic test of the riveting rod. The waterproof lantern core pulling rivet is then used to expand the bolt and the plate together to fill the riveting mold. The bolt foot opens around to produce "buttons", and then the left and right plates are firmly connected.
