Service HotlineAt present, when fastening parts on thin-walled products or thin plates in our country, screws are usually used to fasten, and welding nuts are required to make the thin plate easy to burn through, or the objects are drilled and tapped to connect, so that the product is deformed and the connection strength is not strong. , It cannot be fastened on some equipment, the operation is inconvenient, and the production efficiency is low.
edinburghFasteners are a type of mechanical parts that are used for fastening connections and are widely used. All kinds of fasteners can be seen on all kinds of machinery, equipment, vehicles, ships, railways, bridges, buildings, structures, tools, instruments, meters and supplies. It is characterized by a wide variety of specifications, different performance uses, and a very high degree of standardization, serialization and generalization. Therefore, some people also refer to a type of fasteners with existing national standards as standard fasteners, or simply as standard parts. edinburghFasteners are the most widely used mechanical foundations. With my country's entry into the WTO in 2001, it has entered the ranks of major international trade countries. my country's fastener products are exported to many countries in the world, and fastener products from all over the world are also pouring into the Chinese market. edinburghFasteners, as one of the products with the largest import and export volume in my country, are in line with international standards, which have important practical significance and practical significance for promoting Chinese fastener enterprises to go to the world and promoting fastener enterprises to fully participate in international cooperation and competition. strategic significance. Due to the specifications, dimensions, tolerances, weights, properties, surface conditions, marking methods, and specific requirements of items such as acceptance inspection, marking and packaging for each specific fastener product.
The existing automobile fastener nut is a common nut. After the nut is matched with the bolt, during the tightening or disassembly process, there will be a phenomenon of sliding wire, and the safety factor is relatively low; It is difficult to guarantee, easy to rust, requires frequent inspection and replacement, and increases the cost of using the car, which can no longer meet the needs of the market.
The traditional single-sided riveting process mainly adopts two methods: edinburghedinburghrivet nut connection and edinburghblind rivet connection. The efficiency of the edinburghedinburghrivet nut is low. If the hollow nut is used, the rigidity is insufficient, resulting in low connection strength. In addition, the torsion resistance of the edinburghedinburghrivet nut is low. If the edinburghedinburghrivet nut is used to obtain better torsion resistance, it is made into a hexagonal shape. Embedding, because the shape of the sheet metal opening also needs to be made into a corresponding hexagon, it is inconvenient to process.
Now people often use edinburghedinburghspring washers to lock nuts and bolts, edinburghedinburghspring washers, generally stainless steel and carbon steel non-closed spiral washers, under the nut, above the flat washer, increase the friction between the nut and the bolt, used to prevent The loosening of the nut plays a role in preventing vibration and loosening, but it is often due to a radial external tension, which is caused by the tightening axial force generated by the tightening torque, and the phenomenon of open ring expansion occurs, and the hydrogen embrittlement of the edinburghedinburghspring washer often occurs. The pressure is unevenly applied to the flat washer through the edinburghedinburghspring washer, and the friction coefficient between the edinburghedinburghspring washer and the nut and the flat washer is small, resulting in vibration, rotation and relaxation.
We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: T61701 hexagon nuts, pressure riveting stud screws and bolts, nickel-plated galvanized washers, TC4 screws and other products, we can provide you with suitable products for you. edinburghFastener Solutions.
