What Is a Riveting Machine

A riveting machine is a piece of factory equipment that sets and applies a downward force to a fastener or rivet in order to deform it and bond materials together. These machines are used to speed up production compared with manual riveting, where technicians set each rivet using a hand-held rivet tool. Riveting machines come in a number of styles to suit different fastener types and assembly requirements. They can be powered by electric, hydraulic or pneumatic energy sources.

In general, the main type of riveting machine is the impact or “drop hammer” type. These use a hammer or similar mechanism to deliver the initial setting force, and then a mechanism to spread or “deform” the rivet in a controlled fashion over the length of the fastener or rivet shaft. These machines are usually powered by either a motor and flywheel or a pneumatic cylinder that delivers the force in a self-regulating manner. Some riveting machines do not require an operator to interact with the machine at all, but instead utilize a feed track and hopper to perform the action in a completely automated fashion.

There are also a number of other kinds of riveting machines. For example, a rotary riveting machine can produce a strong, durable rivet with little or no distortion of the head. This style of riveting machine is typically used for applications that require a high degree of strength or resistance to corrosion.

Another type of riveting machine is the radial or orbital forming machine. This uses a series of small wheels to deform the end of the rivet, creating a strong and reliable joint with minimal damage or distortion. This type of riveting machine is typically used for applications in which the rivets must be able to withstand high loads or pressures.

Riveting machine technology has a long history, dating back to such innovations as Joseph Whitworth’s precision measuring tools; William Fairbairn’s rivets and wrought iron furnaces; James Nasmyth’s steam hammers; and Henry and Joseph Maudslay’s marine boilers. The first riveting machines were powered by a manual hammer and had to be operated manually, but now they are powered by electricity or compressed air.

When choosing a riveting machine, manufacturers should consider the type of assembly process they are working with, how much force they need to apply, how quickly they need to complete the fastening process and what kind of space they have available for the machinery. They should also take into account the type of materials they are working with and the size of rivets to be used.

Before committing to a particular riveting machine, it’s a good idea to get an expert opinion from an experienced manufacturer. They will be able to help with the selection of a machine that is the best fit for the application and provide training to ensure the most effective use of the equipment. They can also advise on alternative assembly processes when a specific type of riveting machine may not be appropriate.
