Rivets are commonly used as small components in our daily lives. They are mainly used to connect two parts or components with through-holes, where one end has a cap-like object and the other end is a nail-shaped object. In riveting, the rivet deforms or forms an interference fit to connect the parts together. There are many types of rivets, including R-type rivets, fan rivets, core-pulling rivets (impact rivets), tree rivets, half-round head rivets, flat head rivets, semi-hollow rivets, solid rivets, countersunk rivets, and more.

In the industrial use of large-scale fans, rivets are mainly used for the connection between the blades and the blade handles. For example, Amberma industrial energy-saving fans use 24 rivets to fix each blade to the blade handle, reducing the shear forces on each blade. This type of riveting commonly uses new core-pulling rivets as fasteners. Core-pulling rivets make various structural components compact, lightweight, aesthetically pleasing, easy to use, and cost-effective. Therefore, they are widely applied in industries such as aviation, shipbuilding, automobile manufacturing, machinery, household appliances, electrical instrumentation, building decoration, luggage, and container manufacturing.

Core-pulling rivets are a type of rivet used for single-sided riveting. They require dedicated tools such as rivet guns (manual, electric, or pneumatic) for installation. These rivets are particularly suitable for situations where it is inconvenient to use ordinary rivets that require riveting from both sides. Among them, the open-ended flat head core-pulling rivet is the most widely used, the countersunk core-pulling rivet is suitable for applications requiring a smooth riveting appearance, and the sealed core-pulling rivet is suitable for high load-bearing and sealing requirements.

The international standard for core-pulling rivets is DIN7337, which has many classifications in terms of performance, specifications, etc. Whether used in industrial large-scale fans or other mechanical and electrical equipment, it is important to carefully check and compare, understand the purpose, familiarize oneself with the usage, and choose the appropriate matching rivets.

The HVIST fan was invented by a joint venture between a US and a Chinese company in 1999. After almost 20 years of development, various industrial fans with different numbers of blades have emerged. Currently, domestically and internationally, industrial fans mainly come in three-blade, four-blade, five-blade, six-blade, and eight-blade configurations. In theory, the more blades a fan has, the greater the airflow. However, since industrial fans are generally larger in size, more blades also mean more weight and increased safety risks. Therefore, it is necessary to strike a good balance between airflow and quality. Currently, industrial fans with five or six blades are most popular on the market. These two types are also the main products promoted abroad and have been market-certified for over a decade. As long as manufacturers strictly require high quality and safety for the blades, they can meet market demand.

With the promotion of nationwide fitness, various communities have built indoor basketball courts of different sizes. However, the large span, high height, and relatively sealed building structure of basketball courts pose great challenges to ventilation and cooling. In recent years, many venue constructors have found that large fans (big ceiling fans) can perfectly solve the ventilation and cooling problems, which are tricky for indoor basketball courts.

Industrial large fans have been imported into China from abroad, and batches of industrial fan manufacturers have been continuously researching, developing, and producing a full range of large industrial fan series products suitable for various environmental improvements in China. High-quality large fans are often built on good materials and unique advanced designs. The fan blades of industrial large fans are made of 5052 aviation aluminum, and unique blade designs can maximize the advantages of large fans and meet the needs of different users. When designing fan blades, industrial fan manufacturers need to follow certain principles.
