A hollow rivet is a type of fastener that has a cylindrical shape with a hollow center. Here is a detailed introduction:
Hollow Body: The most distinctive feature of a hollow rivet is its hollow interior, which runs along the length of the rivet. This hollow part can serve various purposes, such as allowing for the passage of wires, fluids, or providing space for deformation during the riveting process.
Head and Tail: Like other rivets, it has a head at one end and a tail at the other. The head is usually larger in diameter than the body and is used to provide a bearing surface when the rivet is installed. The tail is the end that is typically deformed or upset during the riveting process to secure the rivet in place.
Hollow rivets can be made from a variety of materials, including aluminum, steel, copper, and various alloys. The choice of material depends on the specific application requirements, such as strength, corrosion resistance, and conductivity. For example, aluminum hollow rivets are often used in applications where weight is a concern, such as in the aerospace and automotive industries. Steel hollow rivets offer high strength and are suitable for applications that require greater durability and load - bearing capacity.
The installation of a hollow rivet involves inserting the rivet through the holes in the materials to be joined. Then, using a riveting tool, the tail of the rivet is deformed or upset. This deformation causes the rivet to expand and fill the hole, creating a secure connection between the two materials. The hollow center of the rivet can accommodate the deformation more easily, allowing for a better fit and a more reliable joint. In some cases, the hollow rivet may be filled with a sealing compound or other materials to enhance the performance of the joint, such as providing waterproof or airtight seals.
Electrical and Electronic Industries: The hollow structure of the rivet is often used to pass wires or cables through, providing a convenient and secure way to route and connect electrical components. For example, in the assembly of printed circuit boards, hollow rivets can be used to fasten components while allowing wires to be routed through the rivet holes.
Automotive and Aerospace Industries: They are used in the assembly of various components, such as in the construction of aircraft fuselages and automotive body panels. The lightweight nature of aluminum hollow rivets makes them ideal for these applications, where reducing weight is crucial for improving fuel efficiency and overall performance.
Plumbing and Pipe Fitting: Hollow rivets can be used to join pipes and fittings, especially in applications where a sealed connection is required. The hollow center can be filled with a sealing material to prevent leaks.
General Manufacturing: In many manufacturing processes, hollow rivets are used to join different parts together. They offer a simple and efficient fastening method, especially for applications where a traditional solid rivet may be too bulky or where the hollow space can be utilized for other purposes.
