11/5/2023 0 Comments Pop rivet tool air regulatorAir cylinder: Most pneumatic rivet guns come from the factory with lubrication in the air cylinder.The distance from the front of the assembly to the threaded area on the rivet gun’s body should be the same as the distance indicated on the specialized wrench that comes with the rivet gun. Periodically remove the jaw assembly cover to determine whether the jaw assembly is aligned correctly. If not aligned properly, the jaw assembly cannot effectively pull rivet mandrels to install rivets. Jaw assembly: Over time, the jaw assembly can slip from its position.If using the tool continuously throughout a day or several days, lubricate the tool every 1-2 hours. If using the tool over several days, lubricate at the beginning of each day. General lubrication: To manually lubricate a pneumatic rivet gun, put 3 to 4 drops of air tool oil in the gun’s air inlet before the air hose is connected.Or, lubricate it manually with air tool oil. Use a fogger, FRL unit, or oiler to lubricate an air rivet gun. Routine maintenance includes proper lubrication and inspection of the jaw assembly and air cylinder. With regular maintenance, a pneumatic rivet gun can last many years. Important components not visible in this image but discussed in this article: jaw assemblage, jaws, plunger, spring, valve, and piston. The piston (not visible in Figure 2) within the air cylinder moves upward, which operates the components in the jaw assemblage.įigure 2: An air rivet gun and components: nose piece (A), jaw assemblage cover (B), capture cup (C), trigger (D), air inlet (E), and air cylinder (F). When the user compresses the trigger (Figure 2 labeled D), the valve (not visible in Figure 2) at the air inlet (Figure 2 labeled E) opens to allow air to flow into the air cylinder (Figure 2 labeled F). If a pneumatic rivet gun does not have a capture cup, the user tilts the gun downward to drop the mandrel from the jaw assemblage. The capture cup (Figure 2 labeled C) at the back of the rivet gun catches mandrels when they break off the rivet. Spring: The spring pushes the plunger forward towards the jaws when the user is not pulling the trigger.Plunger: The plunger has a v-shaped head, which presses against the jaws to open them when the user is not pulling the trigger. Jaws: The jaws grip the mandrel and pull it back to break it off the pop rivet during installation.The jaw assemblage contains the jaws, a plunger, and a spring. The jaw assemblage cover (Figure 2 labeled B) protects the jaw assemblage (not visible in Figure 2) from debris. The nose piece (Figure 2 labeled A) holds the pop rivet. Pneumatic rivet guns typically come with multiple nose pieces for differently sized rivets. View our online selection of pneumatic rivet guns!Īn air rivet gun has several components.
