METHOD AND APPARATUS FOR PREDICTING TWIST-OUT TORQUE IN A SWAGE MOUNT

摘要

An apparatus for predicting twist-out torque of a swage mount (28) measures work done by a swage ram (36) during a swaging operation. The apparatus includes a position sensor (52) for sensing the position of the ram (36) and a force sensor (54) for sensing the force of the ram (36) during the swaging operation. The apparatus gathers position and force information and calculates swaging work. Swaging work correlates with twist-out torque for a swage mount. Calculated swaging work is compared with a minimum acceptable swaging work value which is related to a minimum acceptable twist-out torque level. If the swage work of a particular swage mount is below the minimum acceptable swage work level, an operator can reswage the mount and thereby strengthen the mount to avoid future failure due to rotation at the swage mount.
