Definition: A bifurcated rivet is a type of rivet characterized by its split shank. It is used for fastening sheets of light materials together. The rivet is secured by spreading and tapping down the two halves of the shank, which hold the sheets in place.
Detailed Description:
- Design:
- Split Shank: The bifurcated rivet features a shank that is split into two or more parts. This split design allows the rivet to expand and secure the materials when installed.
- Head: The rivet typically has a head that provides a surface for holding the rivet in place and distributing the clamping force over the surface of the material.
- Installation:
- Preparation: The rivet is inserted into pre-drilled holes in the sheets of material that need to be fastened.
- Expansion: After insertion, the two halves of the split shank are spread apart and tapped down using a tool or hammer. This action expands the shank and locks the rivet in place, securely holding the materials together.
- Securing: The rivet is secured by the mechanical deformation of the split shank, which creates a strong and stable connection between the materials.
- Applications:
- Sheet Metal Work: Commonly used in sheet metal work and light assembly applications where materials such as thin sheets of metal or plastic need to be fastened together.
- Lightweight Assemblies: Ideal for applications involving lightweight or thin materials where traditional rivets or fasteners may be too bulky or over-engineered.
- Advantages:
- Ease of Installation: Bifurcated rivets are relatively easy to install and require minimal tools. The splitting and tapping process is straightforward and quick.
- Secure Fastening: The split shank design provides a secure and stable fastening, preventing the rivet from loosening over time.
- Low Profile: The design is suitable for applications where a low-profile fastener is needed, as the rivet does not protrude significantly from the surface.
- Considerations:
- Material Compatibility: The bifurcated rivet is best suited for thin or lightweight materials. It may not be appropriate for heavy-duty applications requiring more robust fastening solutions.
- Tools Required: Installation typically requires a specific tool or hammer to spread and tap down the split shank, ensuring a secure fit.
In summary, a bifurcated rivet is a fastener with a split shank used to secure sheets of light material. It is installed by spreading and tapping down the shank, providing a secure and low-profile connection for applications involving thin or lightweight materials.
