Where is self - Clinching nuts used?

Self clinching nuts are also called self tightening nuts and riveting nuts. It is generally used in the fastening field of plates and pipes of various thicknesses (0.5-6mm). Pneumatic or manual riveter can be used for one-time riveting. Rivet nut type: flat head hexagon and half hexagon rivet nut without knurling and blind hole. Also known as pull rivet nut, pull cap and pull cap, it is used in the manufacturing and fastening fields of various metal plates and pipes. It is widely used in the assembly of electromechanical and light industrial products such as automobile, aviation, railway, refrigeration, elevator, switch, instrument, furniture and decoration. In order to solve the shortcomings and development of the welding nut of thin metal sheet and thin pipe is easy to melt and the tapping thread is easy to slide, it does not need tapping thread and welding nut, has the advantages of firm riveting, high efficiency and convenient use. Therefore, we should often use many products.

The utility model relates to a nut, which is round and has convex teeth and guide grooves at one end. It is widely used in sheet metal or sheet metal. The principle is to press the preset hole into the metal plate through the embossing teeth. Generally speaking, the hole diameter of the preset hole is slightly smaller than that of the convex tooth of the rivet nut. The convex teeth of the rivet nut are squeezed into the plate through pressure, resulting in plastic deformation around the hole, and the deformation is squeezed into the guide groove to produce locking effect. Riveting nuts are divided into S-type quick cutting steel riveting nuts, CLS type stainless steel riveting nuts, SP type stainless steel riveting nuts and copper aluminum riveting nuts. Specifications range from m2 to M12. Rivet nuts are widely used in chassis, cabinet, sheet metal and other industries. There is no uniform provision in the national standard.

The commonly used material in the market is iron. Iron is known as carbon steel. It is made of a natural color. In order to prevent rust, it needs electroplating. Stainless steel riveted nuts do not need electroplating. The color of iron plating is generally determined by the customer. It depends on what color the customer needs to plating. There are also some requirements for salt spray time. Some electroplating salt spraying time is slightly higher, some electroplating time is less, and a few hours of rust prevention is less. Another point is to see whether customers need to export this product. Exports are generally environment-friendly, some domestic demand, but most still do not need it. Green blue zinc is usually used in the pressure rivet nut Market, because the spraying test time of green blue zinc salt can reach 72 hours, that is, 3 days. This kind of electroplating salt resistant spraying time is long. In fact, such as electroless nickel plating and nickel salt spraying, the time is relatively short. Generally, it will rust in a few hours, up to 10 hours at most. However, some nickel plating can be carried out in oil, and the salt spray time of oil pressure rivet nut can be slightly longer.
