Riveting 2 or more rivets simultaneously significantly increases your productivity while limiting the number of equipment. Thanks to its unique know-how, GUILLEMIN develops customized multi-rivet solutions to optimize your assemblies.
Here is a typical example with multi-pole circuit breakers which frequently have 5 rivets:
This technique is only used in orbital riveting (in radial, the mechanics in the riveting head would be far too complicated, fragile and expensive).
The "orbital" movement, also called "gyroscopic" is simpler, the tool, called the riveter, describes a cone, so it is relatively easy to manage.
There are two multi-riveting techniques:
- The multi-bolt head: we have a single riveting head, therefore a single “pin” which controls the movement of the head, and several rivets attached to this head.
The rivets must also be at the same “altitude”: all the riveting tools are at the same riveting height.
- The "multi-head box", generally has 2 or 3 heads maximum, where a box controls several independent spindles, each of which controls a head and a riveter
Here the center distances are larger, up to 120 mm maximum. This is found for example in car rearview mirrors, where there are 2 or more rivets far apart from each other.
Another special feature is that you can have rivets at different heights, since each head has its own pin and can be adjusted independently.
