Riveting machine is used to join metal and non-metal materials together. They are available in different sizes, each with a unique head that is used to bind the material together. These rivets are usually installed using a hammer or riveter that inserts them through aligned holes in the parts to be joined. They can also be installed by hand with a special tool or manually driven by the rotary motion of the setting head, which is usually powered by an electric motor and flywheel combination, pneumatic cylinder or hydraulic ram. Riveting machines come in a variety of configurations, from simple single-head hand riveters to complex multi-head automated riveting tools that are electrically or pneumatically (pop riveters, air riveters, and ratchet riveters) or hydraulically actuated.
There are several ways to operate a riveting machine, with the main groups being impact and orbital machines. These are generally divided by how they are powered, with the more common ones being electric, pneumatic and hydraulic. They can be operated in either semi-automatic or fully automatic modes, with some having advanced capabilities such as monitoring the performance of a rivet joint.
The main advantage of self-piercing rivets is their low energy requirement; this means they require less effort to set than other types of rivets and is particularly important in areas where access to the back of the component is restricted, as with many aerospace components, earning them the name ‘blind rivet’. The process pierces the materials on both sides of the joint, deforming the bottom layer of material into a button shape that is then clinched on an anvil to form the rivet head and secure the joint. The result is stronger than spot welding and has lower processing costs compared to other joining methods, but requires a double-sided access to the stack.
Orbital riveting machines use a spinning forming tool that, as it is gradually lowered, forms the rivet into its final shape. This can be a more controlled approach than the impact method and is therefore suitable for projects involving delicate or brittle materials as well as sensitive electronic or electrical components. Cycle times are a little longer than with an impact machine, but the results are very strong and durable.
BM-92 riveting machine is an excellent choice for continuous riveting work, such as in professional workshops. It features a high quality lever, body and mount, and an ergonomic handle. It comes with a range of nozzles from 3.0 to 5.0 mm. It has a robust construction, with stainless steel plates in threaded areas to provide great resistance. Its ratchet system enables you to reduce the amount of effort required for setting, making it a top choice for professional users. It also has a multi-position hose holder to allow for easier access. Safety is a priority, with protective gloves and goggles recommended when operating this type of machine. Always read the operator’s manual and manufacturer’s guidelines for specific instructions and requirements.
