Butterfly nut is a nut shaped like a butterfly, with a unique appearance and function. It is mainly divided into two basic shapes: square wing butterfly nut and round wing butterfly nut. The wings of the square wing butterfly nut are square, while the wings of the round wing butterfly nut are round. This design not only makes the screw look more beautiful, but also increases the strength of the screw.
Manufacturing process
The manufacturing process of butterfly nuts includes cold heading process, casting process and stamping process. The butterfly nuts produced by cold heading process have high precision and are suitable for occasions requiring high strength and high toughness; the casting process is suitable for mass production with low cost; the stamping process is suitable for occasions with simple shapes and low precision requirements.
Application scenarios
The uses of butterfly nuts are very wide, and they are mainly used in the following fields:
1. Mechanical equipment and maintenance: Butterfly nuts are suitable for the manufacturing, maintenance and installation of various mechanical equipment, and are used to fix and connect mechanical parts to ensure the normal operation and stability of the equipment. 2. Medical equipment industry: Because butterfly nuts have the characteristics of insulation, non-magnetic, environmental protection, and anti-interference, they are widely used in medical machinery and equipment to ensure safer use.
3. Wind power industry: Used for the isolation and insulation of chassis circuit PCB boards to ensure the normal operation and safety of power equipment.
4. Aerospace industry: Used for insulation and anti-interference of electronic equipment to ensure the stable operation of equipment.
5. Office equipment industry: Because of its characteristics of never rusting, beautiful and practical, it is widely used in office equipment.
6. Petrochemical industry: High temperature resistance and chemical corrosion resistance, suitable for petrochemical industry, extending the service life of equipment.
7. Electronic industry: Used for insulation, anti-interference, and light weight, suitable for various electronic equipment.
8. Communication industry: Used for insulation, non-magnetic, safety, to ensure the stable operation of communication equipment.
9. Ship industry: Because ships are often immersed in water, the requirements for acid resistance, alkali resistance, and corrosion resistance are very high. Butterfly nuts are widely used because of their long life and high corrosion resistance.
10. Construction, road and bridge engineering, subway construction, high-speed rail construction, auto parts and other industries: butterfly nuts play a vital role in these fields to ensure the firmness and safety of equipment and structures.
Types and processes of butterfly nuts: butterfly nuts are mainly divided into three types: cold-forged butterfly nuts, cast butterfly nuts and stamped butterfly nuts. Cold-forged butterfly nuts are produced by cold-forging process and have strong strength and toughness; cast butterfly nuts are made by casting process.
