Press riveting means that in the process of riveting, under external pressure, the press riveted parts cause plastic deformation of the base material and squeeze into the special prefabricated groove in the structure of riveted screws and nuts, so as to realize the reliable connection of two parts.
Rivet nut, also known as rivet nut, is a kind of nut applied to thin plate or sheet metal. It has a circular shape and one end is provided with embossed teeth and guide groove. The principle is to press the embossed teeth into the preset hole position of the sheet metal. Generally speaking, the hole diameter of the preset hole is slightly smaller than the embossed teeth of the rivet nut. The embossed teeth of the rivet nut are squeezed into the plate through pressure, resulting in plastic deformation around the hole and the deformed objects are squeezed into the guide groove, resulting in locking effect.
