Riveting machinery is used to automatically set rivets in order to join materials together. It offers greater consistency, productivity and lower cost compared to manual riveting. Riveting machines can be used to join wood, metal, textiles and plastics.
There are two broad groups of riveting machines: orbital and impact. An orbital machine has a spinning forming tool that, when gradually lowered, forms the rivet into its desired shape. These machines are more controllable than impact models and have shorter cycle times – sometimes as short as 2-3 seconds per rivet. This makes them a great choice for jobs with delicate components or small spaces.
The type of riveting process determines which kind of riveting machine will be most appropriate for a given application. For example, if the workpieces need to be held in place with clamps while the rivet is placed, an impact machine may not be suitable. However, if the workpieces are to be kept in place by an operator using a rivet gun, an impact machine would be ideal.
Similarly, if the application calls for large diameter rivets, then a hot-upset machine is required to achieve the necessary size and strength. However, if the workpieces require an exceptionally strong joint, then welding is a better option as it produces a much stronger and more rigid structure than riveted joints.
Before choosing a riveting machine, it is important to define the assembly process objectives and process constraints early on. This will help to ensure that the right machine is selected for the job, avoiding expensive mistakes and costly downtime caused by unnecessarily complicated or expensive equipment.
When deciding on the type of riveting machine to purchase, it is also crucial to consider the available floor space. This will influence the footprint of the machine and how many people will be able to operate it comfortably. A smaller footprint will allow for more flexible use of the machine and will reduce the need to change tools between jobs.
Another consideration is the power availability of the plant utilities needed to run the machine. Having sufficient power will enable the machine to perform at its best. Finally, the quality of the rivets produced by the machine will be influenced by its ability to reach the proper pressure and temperatures.
Depending on the application, there are many different types of riveting machines that can be purchased from manufacturers and suppliers. Some are available online while others can be found at local industrial outlets and trade shows. It is important to read and follow the manufacturer’s instructions for operation of any type of riveting machine.
Ideally, the riveting machine should be located in an area with adequate ventilation and a good supply of electrical power. It is also recommended that the machine be kept oiled at all times to ensure proper functioning. In addition, the operator should take the time to clear any jams from the machine and perform other maintenance tasks as needed. Using a riveting machine without taking the proper safety precautions can result in injury and damage to the equipment.
