ABSTRACT:
A crimping machine for attaching metal hose couplings to flexible hose includes a hydraulic actuator for forcing a circular array of die segments toward the narrow end of a tapered opening in the base of the machine in order to radially constrict the die segments and the coupling. The die segments are supported on a die separator in the machine and may be joined into two groups of segments, each individually removeable from the machine to facilitate loading and unloading of the hose couplings. A die ring is placed over the die segments to assure simultaneous movement thereof and to limit the stroke of the actuator, as a crimp diameter limiting device. The die ring is split into halves to facilitate loading. One half of the die ring is removeable and the mating half is slidably mounted on the actuator so as to remain in position over one group of die segments upon retraction of the actuator. An adapter bowl is also disclosed for a smaller range of hose couplings.
