Also known as riveting nut, pulling cap, used in various types of metal sheet, pipe and other manufacturing industry fastening field, widely used in automobile, aviation, railway, refrigeration, elevator, switch, instrument, furniture, decoration and other mechanical and electrical and light industrial products assembly. Developed to solve the shortcomings of metal sheet, thin tube welding nut easy to melt, substrate easy to weld deformation, tapping internal thread easy to slip teeth, it does not need tapping internal thread, does not need welding nut, riveting firm, high efficiency, easy to use.

Types of riveted nuts and uses of riveted nuts

1. Types of riveted nuts

Hexagon semi-hexagon rivet nuts with flat head, small head, with through hole, with blind hole, with knurled and without knurled.

2, the use of riveted nuts

If the nut of a product needs to be installed outside, and the inside space is small, it is impossible to let the press head of the press riveting machine enter the press riveting and the bud and other methods can not meet the strength requirements, then the press riveting and the rise riveting are not feasible. Must be riveted by pull. It is suitable for fastening plates and pipes of various thicknesses (0.5MM-6MM). The use of pneumatic or manual riveting gun can be riveted at one time, convenient and firm; Replace the traditional welding nut, make up for the metal sheet, thin pipe welding fusible, welding nut and other shortcomings.

Rivet nut application range and rivet nut specifications

1. Application range of riveted nuts

Riveted nuts are mainly used in non-structural bearing bolt connections, such as rail buses, highway buses, boat berths and other interior parts of the connection, the improved can prevent spin of the riveted nuts than the aircraft plate nut is more excellent, its advantages are lighter weight, do not need to be riveted in advance to fix the plate nut, the base material back without operating space can still be used.

2. Specifications of riveted nuts

The specifications of the riveted nut in the national standard are M3 M4 M5 M6 M8 M10 M12, in fact, it is recommended to use M6 and M8, because the small thread can be directly tapped on the substrate connection, then the bolt weight is greatly increased, and the connection strength of the riveted nut is limited, that is, the match is not very reasonable.

It can be seen from the above that the riveted nut can be widely used on aluminum alloy substrates of different thicknesses or steel plates with a thickness of 1-2.5mm. In particular, the connection of steel riveted nuts in aluminum alloy components eliminates the complexity of embedding steel plates inside, and its processability is significantly improved.

Riveted nuts for air conditioning applications

1. Riveted nuts can effectively solve the problem of air conditioning housing, forming "yellow water" after a long time, and effectively eliminate problems such as virtual welding.

2. Solve the flanging self-tapping screw connection is not strong, improve reliability, can reduce the noise caused by the loosening of the connection, can be more reliable, practical, and convenient maintenance.

3. Improve production efficiency, reduce the number of workers and reduce labor costs. (Because the riveted nut is used by the press group riveting method, the single welding method is completed at one time, which is not only efficient, but also can reduce the amount of points used.)

4. Use less factory land.

5. Rivet nuts instead of flanging tapping can reduce the material by 20% and save energy

Riveted nuts can effectively solve the problem of air conditioning shell, "yellow water" after a long time, wind and rain, and effectively eliminate virtual welding and other problems.

Solve flanging tapping (or self-tapping nail) connection is not strong, improve the reliability of the connection, effectively reduce the noise caused by loose connection, make the grounding more reliable, practical, and convenient maintenance.
