This low energy consumption system uses digital servo technology to provide a high level of control. It also simplifies tool changing by enabling a robot to utilise multiple tools in a single cell.
The unique engineering of the Henrob electric rivet setter reduces weight and size compared to torque based actuator systems that require much greater motor power. Its design also helps reduce heat generation, which in turn allows the system to run at 100% duty cycle.
Henrob's servo rivet setters, with external strokes up to 220mm, utilise a unique clamping nose that ensures high quality "automotive standard" joints are produced across the full range of rivets and material combinations.
Designed around Henrob's modular concept, the electric rivet setter is fully interchangeable with the hydraulic rivet setter; both types interface with Henrob's range of C-frames and feed systems.
This "mix and match" feature not only rationalises the use of components, it can also be of significant economic benefit by facilitating an upgrade from a prototype-build phase through to production.
The Henrob servo control system is built on a flexible platform, enabling communication with robots and/or full integration with factory systems. The retract stroke can be profiled to minimise cycle time. Process monitoring of each riveted joint and collection and distribution of preventative maintenance (PM) data ensures quality and productivity.
Hundreds of Henrob electric riveting systems have been successfully installed on production lines in Europe and North America, demonstrating excellent reliability in continuous automotive production environments.
These tools set rivets 4mm to 13mm long in demanding 2 to 4 sheet joint combinations that include aluminium sheet, aluminium extrusion, cast aluminium and high strength steel, with and without adhesives.
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.
