Hollow rivets are lighter in weight and have weak nail heads. They are used in riveting places with non-metallic materials that are not loaded with large loads. They are convenient to use and easy to operate.
Hollow rivets use metal material cylinders or metal hoses with a diameter slightly smaller than the broken hole, cross over the product workpieces that must be riveted, and beat or pressurize both sides of the rivet to increase the column deformation and thicken the metal material. The rivet head is generated to prevent the product workpiece from slipping off the rivet. When the product workpiece is separated from the external force, the nail rod and the screw bear the shear stress to avoid the product workpiece from separating.
Hollow rivets are divided into cold riveting and hot riveting. Cold riveting is the riveting of rivets at room temperature; hot riveting is used in areas where the connection is high, such as the steel pillars of iron bridges. The rivets must be heated during hot riveting. The rivet is inserted into the rivet hole, and after the rivet head is punched, the ground stress gathered during the whole process of cooling will make the connection inseparable.
Hollow rivets are mainly used in riveting places where the surface is smooth and the load is not large, and this type of rivet is especially suitable for riveting places where it is troublesome to choose general rivets. It is widely used in engineering construction. Ships, airports, furniture, cars, and other commodities are on the top. Closed blind rivets are used in riveting places with certain sealing characteristics. It is another type of single and double-sided riveting rivet. It is commonly used because the nail head responds and can resist corrosion. It is often stored in the heating furnace of the ship's hull. In the case of riveting in a riveting place with obvious erosion such as a water tank, hit with a hammer to expose the nail core on the top of the rivet head, which can make it flush with the inner hole of the nail head. That is, the actual operation of riveting can be carried out.
For the production and processing level, everyone has always selected China's new technology and processing technology. The key is to have a very good sales market competitiveness. The key is used on the standard parts of the metal sheet main box. The method is divided into fast-cutting steel buried rivet nuts. column. In the case of adoption, you must determine the specifications and categories according to the thickness of the commonly used plates, and solve the surface layer. The stainless steel plate maintains its true color. Customers can also order according to the specifications in the table, and they must be specially customized.
