Abstract:
A load control mechanism for use with a pull type tool (also called a riveter), wherein the mechanism includes a telescopic housing and a compressible element, such as a polyurethane compression spring, which works to limit the ultimate load which is applied by the pull type tool during operation, such as during removal of a rivetless nut plate from a hole in parent material. Also provided is a method of removing a rivetless nut plate by using a pulling head which includes a shock absorber and load limiting device, a resetion cup and a mandrel. The load control mechanism provides that a riveter can be used to safely remove a rivetless nut plate without causing damage or undue wear on components of the tool. This load control mechanism also absorbs operating shocks, protecting expensive work parts (ex: aircraft structure) and the operator during operation, resulting in a safe and ergonomic operation.
