System and process for crimping a fitting to a fluid conduit

摘要

A system and process for performing a crimping operation by which a fitting is crimped to the end of a fluid conduit, and which automatically compensates for one or more variables that can lead to out-of-tolerance crimp diameters, particularly fitting spring-back and crimper deflection. The system and method use a device for inputting into the system a targeted crimp diameter for the fitting, and a crimper for crimping the fitting to the end of the fluid conduit. The crimper comprises a plurality of dies and an actuator for contracting the dies around the fitting to obtain the targeted crimp diameter for the fitting. The system and method further includes a unit for attaining the targeted crimp diameter by automatically compensating contraction of the dies for spring-back of the fitting during crimping and/or deflection of the crimper during crimping.
