Sideways Collar Anvil For Use on A340-600 2005-01-3300

A new method of installing LGP collars onto titanium lock bolts has been brought into production in the Airbus wing manufacturing facility in Broughton, Wales. The feed system involves transporting the collar down a rectangular cross-sectioned hose, through a rectangular pathway in the machine clamp anvil to the swage die without the use of fingers or grippers. This method allows the reliable feeding the collars without needing to adjust the position of feed fingers or grippers relative to the tool centerline. Also, more than one fastener diameter can be fed through one anvil geometry, requiring only a die change to switch between certain fastener diameters. In our application, offset and straight stringer geometries are accommodated by the same anvil.
