A rivet machine is a fastening tool that uses heat to fuse materials together, usually metallic ones. Riveting machines come in a variety of shapes and sizes, ranging from manual hand tools to multi-head automated riveting systems that are electrically, pneumatically or hydraulically actuated. Riveting machinery can be used to join a wide range of materials, including wood, metal and textiles. These fastening tools can be used in a variety of manufacturing applications, such as building furniture, automobile and aircraft parts, machine tools for electronics products, medical equipment and more.
When selecting a rivet machine for a specific application, there are many important factors to consider. The type of assembly process, desired riveting cycle times, footprint requirements for the machine, plant utilities available and finished part aesthetics all play an important role in selecting a fastener tool that will work well in the application. Determining these key attributes up front will help narrow down the options for the most effective tool.
There are several varieties of riveting machines, each offering different benefits for the assembly process. For example, a hot riveting machine uses heat to weld the rivet in place, eliminating the need for adhesives or sealants and creating a solid joint that will not break easily. This type of riveting machine also requires less maintenance, as it does not require an air compressor to operate.
Another variation on the hot riveting machine is a pneumatic hot rivet gun. This riveting tool is powered by pressurized air, and it has a piston that is pushed against the head of the rivet to weld it in place. The rivet gun also has a sliding valve and trigger that control the amount of force applied to the rivet.
For a more precise riveting operation, an impact riveting machine can be utilized. This type of riveting machine sets the rivet by driving it downwards through the materials to be joined and on into a forming tool known as a rollset. The end of the rivet is then shaped with a rolling action, and the result is a very strong and durable join that can resist a lot of pressure.
A ratchet rivet gun is an efficient option for high-level professional use. This riveting tool has a ratchet system that helps to reduce the force needed by operators, and it can be used to set nuts from M-4 through M-12. It is an excellent choice for situations where space is limited and the fastening method cannot be changed, such as when a vehicle or aircraft requires a rivet that is accessible from only one side.
While choosing a riveting machine for your production line, it is important to look for a vendor that offers multiple types of fastening tools and has an unbiased approach to product assembly. A vendor that only offers a single type of riveting machine will not be able to provide you with the best advice for your specific assembly needs.
