Riveting machine is a mechanical fastening process that uses a rivet to join two or more metal pieces together. It is an easy and cost-effective way to make joints that can withstand heavy loads. A riveting machine can be used for a wide range of metal joining applications, including brake linings in vehicles and aircraft, metal brackets, furniture and handles, and window and door hardware. It is a safer alternative to welding because it requires less heat and does not produce fumes during production. It also produces a stronger joint and has good fatigue resistance.
There are many types of rivets, and a variety of machines that can use them. The main groups of riveting machines are impact, orbital and non-impact. Impact riveting machines set the rivet by squeezing it downwards through the materials to be joined and into a forming tool (known as a rollset). This causes the end of the rivet to flare out, resulting in the formation of the second retaining head. This method of riveting is very rapid, with a typical cycle time of about 0.5 seconds.
Non-impact riveting machines set the rivet by a rolling process that compresses it against the workpiece to form it. This type of riveting is typically used for non-critical applications where there are delicate or brittle materials. It is also a safer option than impact riveting because it does not generate as much heat and therefore doesn’t damage the workpieces. It is also suitable for repairing damaged riveted joints. Non-impact riveting machines are available in a variety of forms, from portable handheld riveting guns to multihead automated tools that can be electrically, pneumatically (pop or air riveters) or hydraulically actuated.
The self-piercing riveting process is an excellent alternative to other joining methods for a wide range of materials and applications, such as brittle or soft materials that are difficult to weld. It has the advantage of being a clean process with no fume emissions, and it can be automated using a robotic system. It is also very economical compared with other welding processes, and is capable of producing very high quality joints.
Unlike welding, which creates a permanent and rigid joint, riveted joints are more flexible and have good fatigue resistance. They are also relatively quick to install, making them an attractive joining solution for mass production. In addition, rivets have lower installation costs than bolts and screws.
In order to perform a riveting operation, it is important to choose the correct type of machine and equipment, and to follow all relevant safety guidelines and operating instructions. For example, it is crucial to wear proper personal protective equipment and understand the characteristics of the materials and rivets that you are working with. It is also essential to check the quality of the finished riveting job to ensure that the connection is strong and secure.
