The times are developing and people are making progress. There are more and more industrial plants producing industrial equipment parts, and the types are becoming more and more colorful. The nut is the screw cap, and the nut is made of high-strength steel plate, which is screwed together with high-strength nuts or bolts for tightening parts. High-strength nuts are widely used in sleeve connections or some high-pressure and high-pressure equipment. Especially, they must be disassembled continuously and assembled in various ways, so the demand for nuts is very high. In the process of many nuts, only those nuts that require a relatively large width to be clamped can be called high-strength nuts. High-strength nuts are standard building steels, manufactured according to the cold heading process, and have high interchangeability. Because it refers to the formation of metal plastic processing at room temperature, the deformation of each part is large and the deformation speed is faster. Therefore, the performance requirements of high-strength nut raw materials are relatively strict. Features of high-strength nuts: 1. Easy to assemble, upright, easy to disassemble, and recyclable low-carbon steel is used to produce raw materials. The buckle structure is simple, the mechanical performance is good, and it is detachable, and it is loose under dynamic load. It's a promising way to connect. 2. The high-strength nut is used to tighten the special wrench nut, so that the bolt can generate a huge controllable pre-tightening force according to the nut and the buffer plate, and add the same pre-tightening force to the joint. Under the effect of preload, there will be more friction along the surface of the RF connector. Obviously, as long as the axial force is lower than the sliding friction, the parts will not rotate and the connection will not be damaged. This is the basic principle of high-strength nut connection. 3. It has stronger construction economic benefits. It has simple construction, good bearing capacity, and can be disassembled at will. The most important thing is that the high-strength nut will not be easily loosened during high-strength operation.
