Core pulling rivets, also known as rivets or rivets, are indispensable fasteners for securely connecting diverse metal and non-metal materials. They are especially valuable in scenarios where components must retain superior strength and smooth flatness post-riveting. Here is a comprehensive introduction to the impressive world of core pulling rivets:
1, Structural characteristics
Core pulling rivets consist of two crucial components: the nail rod (also known as the core rod) and the nail sleeve (also known as the rivet body). The nail rod is a robust metal rod featuring threads or specialized shapes, while the nail sleeve is a hollow metal cylinder with precisely aligned threads or grooves on its inner wall, designed to complement the nail rod perfectly. During use, a specialized riveting tool precisely draws the nail rod into the nail sleeve, inducing plastic deformation of the sleeve to securely bond two or more components with unmatched precision.
2, Working principle
1. Preparation stage: Carefully thread the rivet rod of the core pulling rivet through the pre-drilled hole in the substrates to be joined, and gently insert the nail sleeve onto the rivet rod.
2. Riveting stage: Employ advanced riveting tools to firmly grip the tail of the nail rod and apply strategic tension. This tension gradually draws the nail rod into the nail sleeve.
3. Deformation stage: As the nail rod advances, the nail sleeve undergoes strategic compression leading to plastic deformation. The internal threads or grooves securely interlock with the nail rod, forming a robust union.
4. Completion stage: Upon full insertion of the nail rod into the nail sleeve, the riveting tool releases the tension, and the nail sleeve firmly embraces the nail rod, culminating in a solid and durable connection.
3, Advantages
1. Exceptional connection strength: Core pulling rivets establish a bond through plastic deformation, resulting in remarkably high connection strength.
2. Effortless operation: The use of specialized riveting tools enables seamless completion of riveting without necessitating additional heating or welding equipment.
3. Versatile applicability: Core pulling rivets adeptly connect various metal and non-metal materials, and excel particularly in riveting thin plates, pipes, and similar elements.
4. Elegance and smoothness: Post-riveting, components boast a flat and smooth surface, devoid of conspicuous marks or protrusions, ensuring a sleek finish.
4, Application Fields
Core pulling rivets find extensive applications in diverse industries, including automobile manufacturing, aerospace, building curtain walls, electronic equipment, and furniture production. For instance, in automobile manufacturing, these rivets are essential for connecting body components, while in the aerospace sector, they play a vital role in aircraft structure assembly.
In conclusion, core pulling rivets are exceptional fasteners, well-regarded for their power and ease of operation, thereby significantly contributing to a multitude of industries. As technology progresses and application demands evolve, the performance and diversity of core pulling rivets will continue to enhance and expand.
