Type and use of rivet

Commonly used are R-shaped rivets, fan rivets, pop rivets (pop rivets), tree rivets, half-round heads, flat heads, half-hollow rivets, solid rivets, countersunk rivets, pop rivets, and hollow rivets. These are usually used to connect riveted parts by their own deformation. Generally, cold riveting is used for those smaller than 8mm, and hot riveting is used for those larger than this size. However, there are also exceptions. For example, the nameplate on some locks is riveted by the interference between the rivet and the lock body hole.
R-type plastic rivet, also known as expansion rivet, is composed of plastic sub-nail and female buckle. It is unnecessary to use the installation tool during installation. Place the installation base in the smooth hole, and then press the head. The specially designed foot will expand and expand after being stressed, and will be firmly locked on the installed surface. It is often used to connect plastic shells, lightweight plates, insulating materials, circuit boards, or any other thin, lightweight materials. It is beautiful, practical and convenient to use.
The fan rivet is specially designed for manual installation. It can be pulled through the hole of the panel or chassis. It is made of elastomer material and has good toughness. It can be installed quickly even in interference assembly. The design is ingenious and flexible, and it is not easy to slide out after being pulled in with the corresponding hole diameter. The fan rivet is mainly used for fixing the fan, heat sink and chip of the electronic computer case, with anti-vibration and noise reduction.
The core piercing rivet is a new type of riveting fastener that is very convenient for riveting. The core piercing rivet can show its unique advantages in a relatively small space or in the environment where there is no riveting gun or the riveting gun cannot be used. Two or more connected parts can be riveted successfully by using a hammer and other tools to hit the nail core on one side. According to the shape of the cap brim, the core piercing rivets can be divided into flat round head core piercing rivets and countersunk head core piercing rivets. According to the different material combinations, they can be divided into all aluminum core piercing rivets, aluminum steel core piercing rivets, all stainless steel core piercing rivets, steel core piercing rivets, aluminum stainless steel core piercing rivets, plastic core piercing rivets, etc. It is not necessary to use manual riveting gun or pneumatic riveting gun to rivet the core rivet like the pop rivet. It has better riveting performance and convenience, and can be widely used for riveting various connected parts.
Plastic tree rivets, also known as inverted tooth shaped plastic rivets, are also called Christmas tree shaped plastic rivets. The tooth shaped sheet has good elasticity and can be directly pressed and installed manually in the round hole of interference assembly. The tooth shaped sheet can be adjusted and fixed according to the actual thickness. The inverted tooth shaped rivet is designed to be firmly fixed on the installation surface after installation, which is not easy to be pulled out. It is suitable for foam, wood, rubber, Soft materials such as automobile interior decoration shall be fixed between them. Plastic tree rivets have excellent insulation, fire resistance, non-magnetism, heat insulation, light weight, high temperature resistance, high strength and corrosion resistance, and are widely used in various industrial fields.
The types of pull rivets can be roughly divided into open type, closed type, double drum type and single drum type series. The following is a brief description of their respective models. Countersunk blind rivet: riveting of riveted parts with smooth and beautiful surface after riveting. Double-drum blind rivet: during riveting, the rivet core pulls the end of the rivet body into a double-drum shape, clamps the two structural parts to be riveted, and reduces the pressure acting on the surface of the structural parts. Purpose: Mainly used for riveting various thin structural parts in various industries such as vehicles, ships, construction, machinery, electronics, etc. Large brim blind rivet: Compared with ordinary blind rivet, the diameter of aluminum cap of the rivet is significantly larger. When riveting with the connector, the rivet has a larger contact area and a stronger supporting surface, which can enhance the torque strength and withstand higher radial tension. Applicable industry: It is suitable for fastening soft and fragile surface materials and oversized holes. The increased brim diameter has special protection application for soft materials. Closed blind rivet: specially designed to cover the mandrel head after riveting, it is very suitable for various applications with waterproof requirements. It has high shear force, anti-vibration and anti-high pressure.
