Henrob’s loose rivet transfer system is ideal for high volume rivet applications where the economics are attractive for continuous feed. RivTrans is designed to meet high levels of reliability in arduous production environments using in-built intelligence for fault identification and self-recovery.
The use of quick-change parts minimises maintenance and downtime.
A standard system is configured with a bulk rivet storage unit, a separation point for loading a single rivet into a flexible delivery tube, a delivery tube to the rivet setter, and an intelligent nose on the tool for accepting and verifying that the rivet is correctly loaded.
efficient cycle times (typically 2-3 seconds)
feeds a large range of rivets lengths (4mm to 12mm)
can feed rivets over long distances if necessary - over 30 metres
wear resistant delivery tube
direct sensing of rivets in the delivery tube and in the nose
dual feed option - two different rivet types to a single tool
twin feed option – one rivet type to two or more tools
adapted to either hydraulic or electric rivet setters
compatible with robot-mounted riveting tools working in any plane (subject to the limitations of delivery tube movement)
can operate through a robot tool changer
operates on low air pressure – 2 to 3 bar
RivTrans Magazine Feed
As HSPR technology use on robotic production lines has grown, so has the requirement for greater freedom of tool movement and faster cycle times.
Henrob's RivTrans Magazine Feed system enables a tool to be charged with a quantity of rivets sufficient to match a production cycle. Tools are equipped with a storage magazine that is recharged at pre-determined intervals, for example, when a robot moves to a park position. In operation, delivery tubes are eliminated and the tool is separated from its rivet supply source.
The absence of a permanently-connected delivery tube improves reliability and tool access to components. It also provides greater productivity by improving cycle times over conventional blow-feed tools by as much as 50%.
RivTrans Stud Feed Modules
Threaded self-pierce studs are fed only by blow feed methods. Tools may be manual, pedestal, or robotic with feeding possible in any plane. A dual feed model is available where two different stud thread sizes can be fed to a single setting tool.
Henrob | Self Pierce Riveting
Henrob is committed to pushing the boundaries of HSPR technology to new levels. Its philosophy - "an innovator not an imitator" - is realised in a corporate culture based on entrepreneurial and creative flair. We are extremely proud of having in our Henrob family the largest and most talented group of people solely dedicated to self-pierce riveting technology.
Henrob’s philosophy is to design reliable, robust solutions for production. This is achieved with the aid of 3D computer-aided design (CAD) software allowing in-depth modeling of tools and product access studies. Finite Element Analysis (FEA) software is used to ensure adequate life expectancy of components. Design data can be exchanged via the web, e-mail or FTP servers, offering rapid turnaround of rivet joint designs and equipment proposals.
Henrob applications engineers add fastening and assembly expertise to your technical team. After a careful review of your joint and installation needs, they will propose a complete fastener and tool specification suited to your application requirements and production environment. They may even suggest product design changes to allow more efficient assembly.
Whether developing a new product or streamlining assembly of an existing one, you can rely on Henrob's experience and innovation in fastening technology. From standard tools to customised systems, from rivet joint design assistance to automated assembly cells, Henrob can find your optimal solution.
Henrob fastening systems have benefited applications in a wide variety of industries around the world. View our case studies to see how we have helped customers cut in-place costs while improving their assemblies and finished products.
Henrob Self-Pierce Riveting (HSPR) is a cold joining process used to fasten two or more sheets of material by driving a rivet through the top sheet(s) and upsetting the rivet, under the influence of a die, into the lower sheet without piercing it.
