Abstract:
1. A system for crimping a fitting to an end of a fluid conduit, the system comprising: means for inputting into the system a targeted crimp diameter for the fitting around the end of the fluid conduit; means for crimping the fitting to the end of the fluid conduit, the crimping means comprising a plurality of dies and an actuating means for applying a force to cause the dies to travel toward and contract around the fitting to the targeted crimp diameter; and means for attaining the targeted crimp diameter for the fitting by automatically increasing the contraction of the dies around the fitting based on the force applied by the actuating means at the targeted crimp diameter and thereby compensate for at least one of spring-back of the fitting during crimping and deflection of the crimping means during crimping.
