Optimisation, acceleration and automation of blind riveting processes

13 July 2012

Gesipa's proven automatic blind riveting unit GAV 7000 was recently adapted to GAV 8000 eco, electronic and HF versions for better optimisation, acceleration and automation of blind riveting processes. Recently, the company announced three new versions, including GAV 8000 Eco (without process control monitoring), GAV 8000 electronic (with process control monitoring and widely used in automotive production) and the GAV HF used to set high-strength blind rivets.

Stephen Dovernor, account manager (technical sales) at Gesipa explains: “These fully automatic blind riveting units for industrial applications are capable of setting 40 rivets per minute increasing the productivity, saving time and cost by approximately 50% compared to conventional blind riveting tools. This all is possible due to the automatic loading of blind rivet into the gun’s working position. With no skilled staff required, it has a capability of integrating into full automatic production lines and can be flexibly tailored to the specific production requirements of each customer.”

All factors, such as workstation layout, production type, application, securing of reproducible and safe working processes, adaptation to the industrial environment as well as process documentation can be realized using combinations of different pistol versions, lengths of tubing (up to 5m), special accessories for different rivet dimensions and production requirements.

In addition, all GAV units can be equipped with three different versions of setting pistols to adapt them to the workstation and for best access to the rivet locations. Used as part of a complete production system or in self-sustained configuration, the system are quickly and easily adapted where necessary. Both versions of GAV 8000 can also be integrated into robotic systems.

Explaining the different setting ranges for GAV 8000 eco, electronic and HF, Stephen Dovernor says: “The GAV 8000 eco and electronic sets blind rivets from 2.4mm diameter to 6.4mm diameter (aluminium and copper), blind rivets up to 6mm diameter (steel) and up to 5mm diameter (stainless steel) as well as blind rivets up to a head diameter of 11.4mm, offering a setting force of up to 11,770N at 6-7bar air pressure.

"With a GAV HF you can set blind rivets from 4.8mm up to 8.0mm diameter (all materials), rivet shaft lengths up to 35mm, setting head diameter up to 19mm, rivet mandrels up to 5.5mm diameter and it offers a setting force up to 25,000N at 5bar air pressure.”

Using a fully automatic GAV combined with a multi axial robot within a regulated, fast and safe production process offers customers the advantages of high precision, efficiency, short cycle times and superior flexibility.
