Universal jaw mechanism accepts
different rivets
A breakthrough in the design of a universal jaw mechanism for a blind riveting tool, enables different sizes and types of rivet to be easily accommodated and extends the life of the jaws.
A breakthrough in the design of a universal jaw mechanism for a new blind riveting tool by Gesipa, engineering solution specialist and leading rivet manufacturer of Keighley in West Yorkshire, enables different sizes and types of rivet to be easily accommodated, extends the working life of the jaws and reduces demands for service and maintenance With the new range of Taurus blind riveting tools, the likelihood of jamming is minimised due to the precise guiding action of the latest jaw design

Inverter power sources serve robotic MIG welders
ABB has developed ARCITEC II, a new generation of IGBT inverter power sources designed specifically for the robotic MIG/MAG welding of all materials used in metal fabrication.
In addition, application of gripping pressure, through an air-hydraulic actuation, is directly on the mandrel of the rivet while supporting the flange of the rivet during the operational cycle.
Taurus has been ergonomically developed with a capacity up to 8.0mm diameter and a high traction power to set a rivet at up to 16,800N at 6 bar pressure.
The design is one of the lightest available on the market and with an almost undetectable recoil action minimises operator fatigue.

Welding processes tuned 'off-line'
A powerful software tool that gives robot welding engineers full 'off-line' control of the MIG/MAG process provides efficient 'off-line' welding process tuning to predict a wide range of results.
Also incorporated within Taurus is a switchable air-suction control that enables the rivet to be retained in the jaws of the tool when used vertically.
Central to the operation of Taurus is the new jaw mechanism which overcomes a multitude of problems associated with traditional sliding jaw and spring designs.
The jaws are retained totally within the jaw housing and are guided independently through special channels to maintain precise control over their action.
And, as jaw actuation is pneumatic and friction-free, they are able to exert a high gripping force of 60kp and 6 bar pressure directly on the mandrel of the rivet.
With these features the jaws have a very high wear resistance and a single jaw covers all rivet types and sizes up to the capacity of the tool.
Interchangeable nose pieces are always at hand as they are captivated in a base compartment of the tool.
In addition to being very competitively priced due to extensive value engineering, Taurus requires some 30 per cent less air to complete the blind riveting cycle compared to competitor tools.
Automatic two-way broken rivet mandrel evacuation utilises the same compressed air from the tool's setting process with spent mandrels collected in a container which slots into the rear of the tool.
In addition, an extraction tube can be attached to eject spent mandrels to a remote collector.
The entry level Taurus 1 has a 4mm rivet capacity with a stroke of 15mm.
It weighs just 1.6kg and requires only one litre of air for each riveting cycle.
The mid-range Taurus 2 accommodates steel rivets up to 5mm and aluminium rivets up to 6mm while the larger Taurus 3 has a rivet capacity of 8.0mm and still weighs just 1.9kg.
