Pneumatic hydraulic riveting tool

Paul Boughton

GESIPA’s pneumatic hydraulic riveting tool, Taurus series, can save up to 68 per cent of the compressed air by its dual use. This is because, the compressed air required for setting of the blind rivet can be re-used a second time for ejection of the spent rivet mandrel thereby switching-off the air suction mechanism completely through an easy to activate slide switch.

These Taurus Tools were introduced by GESIPA with a process control mechanism.

Explaining the process control mechanism, Stuart Booth, Technical Lead, comments: “Contained within these special Taurus tools, is a sensing and processing capability that analyses each rivet set via a real time analysis of traction and stroke during the riveting operation. An immediate feedback is provided to the operator via Green and Red LED’s located on the tool to confirm good or bad rivet setting. Rivets that fail to set according to defined parameters are detected and reported.”

Multiple job profiles stored in a computer can be quickly down-loaded into the tool’s memory, programming it for varying applications. The tool’s internal memory stores data on up to 260,000 rivet sets. The output data can be transmitted in real-time to collection devices, audible/visual signal systems and electronic controllers or downloaded at intervals to provide analysis of the riveting process.

The system also identifies failure patterns and memorizes those for failure analysis and troubleshooting.

Considering all the work that is done by these special Taurus tools, it is notable that all the system components involved are part of the tool itself and each analysis takes less than a microsecond. Moreover, all measurement parameters and riveting sequences can be adjusted with special software. Detailed analysis of the measurement either for data storage or for error detection, as well as sensor re-calibration can be performed at user’s level.
