The riveting nut is a kind of nut applied to the thin plate or sheet metal. The shape of the nut is circular, and the embossed tooth and guide groove are provided at one end. The principle is that the apertures are pressed into the sheet metal by the embossing teeth, and the diameter of the square preset hole is slightly smaller than the embossing teeth of the pressure rivet nut, and the pressure of the pressure teeth of the pressure rivet nut is squeezed into the plate. The periphery of the hole is plastically deformed, and the deformation is squeezed into the guide groove to produce a locking effect.
Press rivet nut is divided into quick cutting steel pressure rivet nut S type, stainless steel pressure rivet nut CLS type, stainless steel pressure rivet nut SP type and copper and aluminum pressure rivet nut type CLA type, which should be used in different environments. . Specifications are usually from M2 to M12.
The riveting nut does not have a uniform national standard. The earliest riveting nuts came from American manufacturers. After being introduced domestically, they gradually formed the current industry standard and were accepted by the chassis cabinet and the sheet metal industry.
Pressure rivet nut application technical guide:
1. The S series pressure riveting nuts are made of free-cutting iron and processed after heat treatment. The CLS series pressure riveting nuts are made of easy-to-use and easily-cut stainless steel, and the surface is not treated.
2. The hardness of low-carbon steel plates must be less than 70 RB, and the hardness of stainless steel plates must be less than 80 RB.
3, for a variety of thickness of the plate, the minimum thickness of 0.8mm, must be used according to the thickness of the plate and the nut size, in order to determine the A-size corresponding to the tail number Z, the user according to the thickness of the plate according to the table in the tail number sample selection;
4, according to the aperture size to be precisely controlled, according to the 0-+0.075mm tolerance size processing, it is best to punch, the nut should generally be installed from the plate "disconnected" surface The installation process is generally achieved through the "pressure riveting" operation, and it must not be impacted
