Answer what is pressure riveting

The so-called pressure riveting refers to the plastic deformation of the body material under external pressure during the riveting process, and squeezing into the special prefabricated groove in the riveting screw and nut structure, so as to achieve the reliability of the two parts. The way to connect. Ordinary low-carbon steel, aluminum alloy plates, and copper plates are suitable for crimping pressure riveting nut posts. For stainless steel and high-carbon steel plates because of their hard material, special high-strength pressure riveting nut posts are required, so there are pressure riveting nut posts and As far as possible, the sheet metal parts of pressure riveting nuts should not be made of stainless steel.

Including pressure riveting screws, pressure riveting nuts is also the case, not suitable for use on stainless steel plates. There are two types of non-standard nuts for pressure riveting, one is pressure riveting nut column and the other is pressure riveting nut. This riveting form is used to realize the connection with the base material, and this riveting form usually requires the hardness of the riveted parts to be greater than the hardness of the base material.
