A spin rivet is a type of rivet that is set using a specialized process where the rivet is crushed from above by a rotating tool to deform and secure it in place.
This method, known as spin riveting, employs a press with an angularly mounted special tool. The rotating tool applies pressure to the rivet, deforming it in a controlled manner to create a strong and permanent joint.
Here's a breakdown of the spin riveting process:
- Preparation: The rivet is inserted through the materials to be joined.
- Tool Application: A rotating, angularly mounted tool is pressed against the head of the rivet.
- Deformation: The rotating pressure causes the rivet material to flow and deform, creating a secure, mechanically interlocked joint.
- Finishing: The tool completes its cycle, leaving a formed rivet head and a strong, permanent connection.
Key Characteristics of Spin Riveting:
- Cold Forming Process: Spin riveting is a cold forming process, meaning no heat is applied during the deformation of the rivet.
- Controlled Deformation: The process allows for a high degree of control over the deformation of the rivet, resulting in consistent and reliable joints.
- Speed: Compared to some other riveting methods, spin riveting can be relatively quick, making it suitable for high-volume production.
- Versatility: Spin riveting can be used with a variety of rivet materials and joint configurations.
Spin riveting is commonly used in applications where strong, reliable, and aesthetically pleasing joints are required.
