Sheet Metal Clinching Tools
Sheet metal clinching tools are specialized dies used in rivetless joining machines. By applying massive pressure to multiple layers of sheet metal, the tools induce cold plastic deformation within the die cavity, forming a permanent mechanical interlock. This process joins the sheets together without the need for additional rivets, screws, or filler materials.
Key Advantages
- Zero Rivets: Eliminates costs related to purchasing, storing, and managing rivets, thereby reducing overall manufacturing expenses.
- Superior Sealing: The plastic interlocking of metal-to-metal creates an airtight and waterproof joint, often outperforming riveted connections in sealing integrity.
- Multi-Material Compatibility: Capable of joining coated or plated sheets and dissimilar metals (e.g. aluminum to steel) without the risk of electrochemical corrosion associated with welding.
- Eco-Friendly Process: Low energy consumption with no smoke, sparks, or thermal deformation, making it an ideal choice for green manufacturing.
- Extreme Efficiency: A single press cycle takes approximately one second, making it perfectly suited for high-volume automated production.
- Clean Aesthetics: Results in a flat surface on one side and only a minor protrusion on the other, providing a visually appealing finish.
Selection Recommendations
To ensure a tailored solution, please provide the following technical data:
- Technical Specifications: Detailed engineering drawings or physical samples, including the total stack thickness of the workpieces.
- Material Composition: Clear definition of material grades and individual layer thicknesses for the components to be joined.
Usage Recommendations
- Supplier Selection: It is recommended to use dies provided or suggested by the riveting equipment manufacturer to ensure optimal compatibility and after-sales support.
- Maintenance Protocols: Regularly clean the die cavity to prevent damage from metal shavings; handle with care to avoid impacts; and maintain detailed usage and maintenance records
