The main advantage of stainless steel rivet nuts is that there is no operating space on the back of the substrate, and the quality is extremely light. Today, the editor will talk about the selection principles of stainless steel rivet nuts and their uses: 1. The mechanical properties of stainless steel rivet nut materials, especially the strength requirements; Corrosion resistance requirements of materials;
The lifting ring screws are generally not surface treated, but according to the requirements, surface treatment such as galvanized passivation and chrome plating can be carried out, and it is specified in GB5267-85. The chemical composition and mechanical properties of the material should be treated immediately after electro-galvanizing. The test methods are specified in GB699. During routine inspection, the grain size test may not be advanced, and the grain size test method shall be in accordance with the provisions of YB27. Thread inspection is performed with thread gauges and smooth limit gauges or universal energy tools.
Riveting nut tool is a special installation tool for riveting nut, including pneumatic riveting nut and electric riveting nut. Pneumatic riveting nut tool has the advantages of fast speed and large pulling force, but it is difficult to rotate into and unscrew the riveted nut. The rotating blade of the moving motor is frequently used or in a slightly dusty working environment, it will suddenly get stuck and not work, there is a great hidden danger of motor crash, and the torque of the air motor is small due to the limitation of the volume, although the riveting pulling force can be done to larger defects, but the volume also increases.
screw is a type of fastener that cooperates with threaded holes for combining various parts into one assembly and making the parts easy to assemble or disassemble. However, when the assembly containing the screw is used in a special environment, such as outdoor use or use in a liquid environment, there are requirements for preventing the leakage of liquid through the screw joint and preventing the screw from loosening at the screw joint. The screw structure does not have such a function. In the prior art, when there is a need for leakage prevention and loosening of the screw, a rubber washer is usually added between the screw head of the screw and the locking surface of the locked part, or the thread part of the screw is wrapped to prevent Leakage tape and then add anti-loose washers between the screw head of the screw and the locking surface of the locked part, so as to achieve the purpose of preventing leakage and loosening. However, the use of washers not only increases the thickness and weight of the assembly, but also requires an additional process during assembly, which is labor-consuming and labor-intensive. In the process of screwing, it is easy to cause uncertainty to the rubber washers due to the shear stress of the screws. Leakage occurs due to damage and deformation, and the practice of wrapping leak-proof tape around the screw teeth is often prone to damage to the threaded holes.
Existing bolt and nut connections usually use threads for connection, and this connection method has two main drawbacks. First, tools are required to be used to lock it during installation, and it takes a long time to complete, which is time-consuming and labor-intensive; Second, the installed bolts and nuts are prone to loosening after a period of time, resulting in loosening and shaking between the connecting parts. Therefore, there is a need for a bolt and nut fastener that is easy to install and can effectively prevent the loose fit of the bolt and nut, so as to solve the problems existing in the prior art.
