Rivet nut is a novel and practical fastener, which brings profound changes to the joining process of thin plates. Welding nuts on thin wrenches or drilling and flanging on thin soil, the traditional tapping enzyme method is completely replaced. So, what are the main types and uses of riveted nuts?
Riveting nuts, also known as riveting nuts, pull caps, instant pull caps, are used in the fastening fields of various metal plates, pipes and other manufacturing industries. They are currently widely used in automobiles, aviation, railways, refrigeration, elevators, switches, and instruments , Furniture, decoration and other electromechanical and light industrial products. It was developed to solve the shortcomings of easy melting of thin metal plates and thin tube welding nuts, easy welding and deformation of base materials, and easy slippage of internal threads. It does not require tapping internal threads, nor does it require welding nuts. Easy to use.
Kite rivet nut type: flat head small head hex hex half hex rivet nut, with through hole, blind hole, knurled and non-knurled.
The purpose of riveting nuts: If the nut of a certain product needs to be installed externally and the internal space is narrow, the pressure head of the riveting machine cannot be input. Pressure riveting and sprout extraction cannot be achieved. When strength is required, pressure riveting and expansion riveting are not feasible . Must use riveting. It is suitable for the fastening field of plates and tubes (0.5MM-6MM) of various thicknesses. The pneumatic or manual rivet gun can be used for one-time riveting, which is convenient and firm; it replaces the traditional welding nut to make up for the welding of thin metal plates and thin tubes, and the welding nut is not smooth.
Riveted nuts are mainly used for non-structural load-bearing bolt connections, such as the connection of internal parts such as railway passenger cars, highway passenger cars, and boats. It is better to prevent the nut from rotating than the pallet of the airplane nut. Its advantages are lighter weight, no need to fix tray nuts and rivets in advance, and there is no available operating space on the back of the substrate.
The current specification for riveting nuts in the national standard is M3M4M5M6M8M10M12. In fact, it is recommended to use M6 and M8 because it is possible to tap directly on the substrate. If the thread is large, the bolt is heavy. In order to increase, the connection strength of the riveted nut is limited, that is, the matching is unreasonable.
It can be seen from the above that riveting nuts can be widely used on aluminum alloy substrates with different thicknesses or thicknesses of 1-2.5mm on steel plates. In particular, by connecting the rivet nut to the aluminum alloy component, the cumbersome process of embedding the steel plate inside is eliminated, thereby greatly improving its manufacturability.
