Abstract

This disclosure relates to a crimp head for a crimp machine particularly suited for crimping hose and fitting assemblies, the head comprising two die halves which are movable on a line of movement toward and away from each other. Each of the die halves comprises a web and a support for the web, and each web forms a plurality die guideways. The head further comprises a set of substantially identical dies, half of the dies being slidably mounted in the guideways of each web. The halves are movable on the line between an open position wherein a fitting to be crimped may be mounted on a fitting axis between the halves, and a crimp position wherein the halves close together and crimp the fitting. The fitting axis is substantially perpendicular to the line of movement of the halves, and the dies are movable in the webs radially of the axis. Each half further comprises a pusher having a V-shaped surface for engaging the dies and pushing them against the fitting. A crimp head may be mounted in a portable hand-held crimp machine, or a plurality of crimp heads may be mounted in a multiple-head machine, the crimp heads being designed for different size fittings. The multiple-head machine has one operating station, and the heads are selectively movable to this station.
