Once the supply hose is secured into the fitting, with the air rivet gun pointed downwards or away from people, pull the trigger so that the air can distribute the oil inside the gun evenly ready for use. To lubricate the rivet gun, you must apply oil to the built-in fitting on the gun before connecting it to the air compressor. This is a critical step into minimizing the friction among the moving parts inside the gun while also ensuring that the same pressure setting consistently delivers the same result. This is where the significance of the pneumatic rivet gun comes into play.īefore the rivet gun can be used, it is very important that it is lubricated. the quality of the hole through which the rivet goes.the characteristics of the rivet itself.The quality of pneumatic riveting is largely dependent on three things: This is why riveting is essential in ensuring that the airframe will be able to withstand the extreme tension, compression, and torsion stresses it undergoes during flight. In aircraft assembly, you must join together several sheets of material to form the airframe or fuselage of the aircraft. Now imagine having to do that all manually, it would take a ridiculous amount of time and strength! It is said that a Boeing 747 aircraft contains around 1 million rivets.
#Rivet gun uses install#
The rivets are driven through previously drilled holes of the adjoining surfaces, and then one end is bucked or deformed to lock the surfaces into place.Īn air rivet gun allows users to drive and install blind rivets through two or more components to bind them together. To put it simply, riveting is the joining of one surface to another using a rivet. Instead of tools and brute strength, rivets could be attached far more efficiently, more cleanly, and with a lot less effort. Save my name, email, and website in this browser for the next time I comment.Pneumatic rivet guns changed the construction and manufacturing industries more than a century ago. The disadvantage of relatively poor resistance to vibration is addressed well by a range of vibration resistant and locking nuts as well as thread lock. Machine screws and bolts offer an extremely useful combination of high strength, compatibility with a range of commonly available tools and easy disassembly and reassembly with fastener reuse. Additionally, they are difficult to remove.
The disadvantages of using solid rivets are that highly specialized and costly installation equipment must be used which requires good access from both sides of the assembly. Furthermore, once the heads of a solid rivet are formed the fastener is almost completely immune from vibration.įor these reasons solid rivets continue to be the preferred fastener for critical applications such as aircraft structures and steel bridges.
#Rivet gun uses crack#
This is higher even than possible for a threaded fastener since threads create potential crack initiation sites. They are available in high-strength steels and aerospace alloys, and their solid shaft is able to transmit the greatest possible shear force for a given hole size. A drill bit can be easily seated in the hollow end and used to remove the head.īy contrast, solid rivets are perhaps the strongest mechanical fastener available. A benefit of the hollow shafts and softer metals used for pop rivets is that it makes removal relatively easy. Heavy-duty pop rivet tools can install higher strength fasteners, such as stainless steel, but their strength is still limited by the requirement for a hollow shaft. Light-duty riveting tools are only able to upset aluminum rivets, which provide low-strength fastening. The strength of the materials used also depends on the power of riveting tools available. Pop rivets use a hollow shaft, reducing their ability to resist shear loads. Some advantages of rivets include resistance to vibration, low-profile heads, and the rapid, low-cost assembly where large numbers of fasteners are required.įor typical workshop applications, where pop rivets are usually used, threaded fasteners will provide superior strength. The advantages of machine screws and bolts are easy disassembly and reassembly, the ability to reuse the fastener, and the availability of such fastening tools. The choice of using threaded fasteners, such as machine screws, or rivets depends on many factor and is complicated by the wide range of fasteners available. Screws provide convenient disassembly and reassembly while rivets provide economical and reliable fastening.
