What is a Pneumatic Rivet Nut Gun?
1. Definition and Working Principle of a Pneumatic Rivet Nut Gun
A pneumatic rivet nut gun is a fastening tool driven by compressed air, specifically designed to install rivet nuts onto substrates like thin metal, plastic, and composite materials. The working principle involves generating a pulling force through pneumatic power to expand the rivet nut’s barrel and tightly press it against the substrate, creating a secure threaded connection that allows screws or bolts to be firmly fixed onto the material.
Working Process of a Pneumatic Rivet Nut Gun:
- Install the rivet nut: Place the rivet nut into the gun’s head and screw it onto the threaded mandrel.
- Apply pulling force: Press the trigger to activate the pneumatic system, pulling the mandrel backward, which forces the rivet nut to expand and press tightly against the substrate.
- Complete the riveting: Once the rivet nut is fully secured, the mandrel automatically retracts, completing the installation process.
- Continue the operation: Repeat the process to perform batch installations, enhancing production efficiency.
