Riveting machines have been used for centuries to join two or more pieces of metal together. In the past, this was done by hand with a hammer and chisel, but as technology advanced, so did riveting machines.

Today there are several types of riveting machines available, each designed to meet specific needs in terms of speed, strength, and accuracy. From pneumatic-powered models that can quickly assemble large parts to precision electric-operated machines for intricate components, these tools offer manufacturers a wide range of options when it comes to joining metal components.

Let's take a closer look at some of the different types of riveting machines available today.

Different Types of Riveting Machines 

There are three main types of riveting machines, each with its own unique method of forming the head of a rivet.

Compression Riveting
Compression riveting involves using a machine to pull or squeeze the shank of the rivet, creating a head through the application of force. This type of riveting is used in situations where precision and uniformity are important, such as in aircraft or automobile manufacturing.

Impact Riveting
Impact riveting involves the use of an impacting tool, such as a riveting hammer, to strike the top of the shank and form the head of the rivet. This type of riveting is often used in construction and repair work where a quick and efficient method of joining materials is needed.

Nonimpact Riveting
Nonimpact or orbital riveting uses a rolling or spinning action to form the head of the rivet. This type of riveting is used in applications where a high level of precision is required but without the need for the application of significant force. Nonimpact riveting machines are often used to manufacture electronic components, where delicate materials require a gentler method of joining.

Types of Rivets

When selecting a riveting machine, it's important to consider the type of rivet being used. Rivets come in many shapes and sizes, and each type requires a specific machine for the best results. Common types of rivets are as follows:

• Solid Rivets: These have a solid body with no internal cavities. The protruding end can be bent, hammered, or twisted to create a secure connection. However, they can be challenging to attach, requiring powered machinery.
• Blind Rivets: Ideal for use when access to both sides is not possible, they have an integral mandrel that creates an upset on the blind end of the rivet. The mandrel is pulled into the body, breaking at or near the intersection of the mandrel and its upset end. Blind rivets are often used as an alternative to solid rivets.
• Tubular Rivets: These have a cylindrical hole running through the headless end, which exceeds 112% of the rivet's shank diameter. They are designed to be secured by spreading the end and are commonly used in self-piercing applications. They are used extensively in the aerospace, automotive, and industrial sectors.
• Semi-Tubular Rivets: These have a hole in the opposite end from the head, the depth of which does not exceed 112% of the shank diameter. They are similar to solid rivets but require less insertion force, allowing for longer rivets to be used. They are used in riveting impact applications, with the end of the rivet flaring outward upon impact until it rolls up against the workpiece.
• Compression Rivets: Made up of two components - a solid male rivet and a tubular female half - these are inserted into a pre-drilled hole. The solid rivet is matched to the hole diameter in the tubular half, creating a compression fit when the two halves are squeezed together.
• Split Rivets: Also known as bifurcated rivets, these have two shanks that spread apart once they've been inserted.
• Drive Rivets: These have a pin that protrudes through the head of the rivet. They are typically installed using a hammer or pneumatic tool to drive the pin into the shank of the rivet, making them ideal for retaining panels of varying thicknesses.

Common Applications for the Use of a Riveting Machine 

• The aerospace and automotive sectors rely on riveting for its lightweight and high shear strength. It's often used in aircraft assembly and the joining of aluminum sheets for vehicle body panels.
• Woodworking and decorative crafts benefit from riveting, seen in the creation of plywood road cases, photo frames, and hinges.
• When welding is impossible due to high-temperature changes in properties, riveting comes to the rescue, providing a secure fastening solution for sheets of dissimilar materials.
• The jewelry industry finds riveting to be a valuable tool, allowing the joining of fine jewelry parts without the need for soldering or heat.
• Building and construction also utilize riveting, from metal-framed structures to fiberglass roofing and bridge construction.
• From kitchen utensils to cookware and even knives, riveting is ubiquitous in the kitchen.

Final Words

Riveting machines provide a reliable, secure method of fastening two surfaces together. With the right machine and rivet type, you can join any material with precision and consistency. The myriad applications make it an essential tool for any manufacturing environment. Keep in mind the specific needs of your project, and you'll have the best results with your riveting process.
