A Riveting machine is a custom machine designed and built specifically for a particular riveting process. Riveting processes are ideal to automate because they require repetitive action and a high input force. The riveting process itself involves fastening two laminated materials together with a metallic fastener called a rivet. There are several types of riveting processes that can be automated, and each requires a different type of machine.

Before choosing a rivet machine, consider your assembly process and the specific material you want to join. You will also want to know how many rivets you need to fasten, and if there are any specific sizes you need to use. Defining these requirements will help narrow down your options and enable you to choose the right machine for the job.

For example, if you are using a riveting machine to fasten metal brackets to a piece of wood, you might need to use a smaller diameter rivet. If you are joining sensitive electronic or brittle materials, you might need a different type of machine.

You will also need to decide if you want to use an impact or orbital riveting machine. The former works by driving the rivet downwards through the materials to be joined and into a lower-form tool, which sets the head of the rivet. This allows the rivet to quickly connect and bond the materials. This type of machine has a shorter cycle time and can be used for high volume manufacturing.

On the other hand, an orbital riveting machine uses the same concept but with a rotating tool. The rivet is drilled through the materials and then into the tool, which sets it by a rotating action. This provides a much smoother connection and helps prevent damage to the materials.

Another option is a hot upset riveting machine, which uses heat to melt the head of the rivet and set it into place. This can be very effective for delicate or brittle materials, and can be used for high-volume manufacturing.

Rivet guns are another popular choice for automatic riveting machines, and can be used with a variety of different riveting processes. They are easy to operate and provide a very consistent result. They can also be robot mounted to save space in the factory, and provide an excellent way of reducing labour costs.

Blind (pop) riveting is one of the most common forms of riveting, and can be easily automated. This process inserts a rivet gun into a hole through multiple laminated sheets, and then snaps the mandrel shaft off of the end of the rivet, which causes the end of the blind rivet to expand and curl around the hole opening, binding the laminated materials together. This type of rivet is commonly used in automotive applications, and is often a cost-effective solution for high production volumes.

For the most efficient and safest results, you should always consult with an experienced operator and follow all manufacturer guidelines for a given riveting machine. Depending on the type of riveter, this may include specific safety measures, operating instructions, and maintenance procedures. It is also recommended that you wear the appropriate personal protective equipment when working with a riveting machine, especially when assembling or dismantling it.
