Abstract
The reliability of a gas pressure regulator is ensured through the use of the disclosed integrated crimp bias apparatus and method for biasing and crimping components of a diaphragm subassembly for the regulator. Omission of crimping of the components after biasing during forming of the diaphragm subassembly for the regulator is avoided by automatically locking at least one of the components of the subassembly in the apparatus before biasing and automatically releasing the locking only after crimping of the biased components. A pincerlike crimper of the apparatus includes a pair of pincers working on a pivot, each pincer having a handle to which a force can be applied and a grasping jaw for exerting a crimping pressure on the components. Grasping jaws each have two crimping elements which oppose respective ones of the crimping elements on the opposing grasping jaw during crimping. A fixture holds the components to be biased and crimp connected. The fixture and components held therein are moveable into and out of a position for crimping from an initial position thereof where biasing is performed.
