Abstract
Device for swaging a loose fitting onto a core. The device has at least two opposed coplaner swaging tools each rotatable about a fixed axis and together forming a swaging station. Pusher means are provided for pushing the fitting through the swaging station while at the same time rotating the tools about their axes.
Claims4
A device for swaging an article having at least two opposed coplanar swaging tools forming a swaging station and where each tool is mounted for rotation about a fixed axis, characterized in having pusher means including a piston movable in a hydraulic cylinder for moving said article towards said swaging station such that said article initially contacts said swaging tools at an entry side of said swaging station and such that continued movement of said pusher means forces said article completely through said swaging station whereby each said tool will be rotated about its fixed axis to form said article and whereby said article will be ejected from an exit side of said swaging station, and return means for rotating said swaging tools to a point where they may again be engaged by an article, said return means including a return tension spring operatively positioned between each said swaging tool and said piston whereby the return tension springs will urge said swaging tools in a direction towards the entry side of said swaging station.
