Riveting machine is a device that can be used to set rivets or rivet nuts in sheet metal parts to join them permanently. It can be operated manually or automatically. It is ideal for professional use. It uses a spring to provide the downward force required to deform the rivet. It has a set of nozzles and can be fitted with 2.4, 3.0, 4.0 or 4.8/5.0 nozzles to fit different sizes of rivets. Its handle is made of high-density cast aluminum for greater resistance.
The most important aspect of a riveting machine is that it can generate a steady, consistent flow of pressure and heat in order to effectively deform the rivet and create a strong bond between the materials. This is especially important when it comes to riveting aerospace parts and other high-stress areas. A riveting machine can be powered by a pneumatic or hydraulic cylinder to deliver the required force.
There are many different types of riveting machines available on the market, each designed for a specific application. The most common are impact and orbital riveting machines. Both offer a number of advantages over traditional hand-held riveters. These include a faster cycle time, the ability to use larger rivets, and the fact that they can produce stronger, more fatigue-resistant joints. Additionally, the machines can be equipped with a variety of process monitoring systems to ensure that quality standards are met.
Orbital riveting machines are available in either a pneumatic or hydraulic version and offer a more controlled downward force than impact machines. The lower forces also allow for higher tolerances. This type of riveting is ideal for sensitive assemblies, as it can be used without damaging the materials. This type of machine can also be used to achieve a high-quality finish on the materials, as it is less likely to leave burrs or other defects.
Another subset of orbital riveting is radial riveting, also known as rollerforming. This differs from orbital forming in that the rivet head is spread out rather than being hammered into a shape. In addition, radial riveting can be done with relatively small amounts of force. This is a great option for applications where a high-quality finish is required, as the process produces little or no vibration and allows for a smooth distribution of force over the entire area being riveted.
Riveting is a very popular joining method for metal, and it has several advantages over other methods, such as welding. It is particularly suitable for dissimilar or non-ferrous materials. It can also be performed on brittle materials, which would be damaged by high heat. In addition, riveted products can usually be disassembled for a quality inspection without damage to the parts. In contrast, welded joints are often prone to corrosion or other forms of damage during disassembly. In addition to these benefits, it is a very clean process with low energy requirements. It is often preferred over spot welding for its ease of operation and the lack of fumes.
