Butterfly nut is a commonly used fastening element, which is named because of its butterfly shape. It is widely used in various mechanical equipment, bridges, buildings and other fields of fastening connections. In recent years, with the rapid development of China's economy, the demand for butterfly nuts is also growing. Among the many butterfly nut products, polished butterfly nut is favored by many customers with its excellent performance and beautiful appearance.
First of all, let's understand the structure of butterfly nut. Butterfly nut is generally composed of three parts: screw, butterfly plate and nut. The screw passes through the butterfly plate and the nut, playing a connecting role. The butterfly plate is butterfly-shaped, so that the butterfly nut in the fastening process can produce greater torque, thereby improving the reliability of the connection. The nut plays a fixed role, so that the butterfly nut will not loosen after tightening.
Polished butterfly nuts have their surfaces polished during the production process. Polishing is a process of making the surface of an object bright by means of abrasion and impact. The surface of polished butterfly nut is smooth and beautiful, and it has the following advantages:
1. Improvement of connection performance: Polishing treatment can remove the microscopic defects on the surface of butterfly nut, such as oxidized skin, pits, etc., so as to improve its coefficient of friction with the screw and enhance the connection performance.
2. Corrosion resistance: polished butterfly nut surface smooth, not easy to adhere to corrosive substances, has a strong corrosion resistance, suitable for wet, corrosive environment.
3. Beautiful and generous: polished surface of the butterfly nut is bright and shiny, with good visual effect, which helps to improve the overall aesthetics of the product.
4. Improve service life: polished butterfly nuts have smooth surface, small friction coefficient, not easy to wear and tear, so as to improve service life.
5. Easy to maintain: polished butterfly nuts have smooth surface, not easy to attach dust and dirt, easy to clean and maintain.
In practical application, polished butterfly nuts can be made of different materials and sizes according to customers' needs. For example, carbon steel, stainless steel, aluminum and other materials, as well as different specifications of thread length and diameter. In addition, polished butterfly nuts can also be specially treated according to customer requirements, such as zinc plating, nickel plating, etc., to meet the needs of different environments and application scenarios.
In a word, polished butterfly nuts occupy an important position in the fastening components market by virtue of their excellent performance and beautiful appearance. With the continuous development of China's economy, the application range of polished butterfly nuts will become more and more extensive, and the market demand will also continue to grow. Therefore, improving the production efficiency and quality of polished butterfly nuts will be an important issue for fastening element enterprises.
