ABSTRACT:
This disclosure relates to a machine for attaching a fitting to a length of hose by crimping. The machine comprises a base plate and a die set which is positioned on and supported by the base plate. A power unit is mounted above the base plate and the die set, the unit including a movable ram and a ram extension which is pivotably connected to the ram. A die bowl is positioned over the die set, and the power unit is operable to drive the ram extension against the die bowl, this action crimping a fitting positioned in the die set. The ram extension is attached to the ram for pivotal movement on an axis that is perpendicular to the ram movement, so that the extension is movable up and away from the die set. The die set includes a die plate and die segments on the plate, and the die bowl is positioned around the segments. The die bowl is separable from the die set, and a spacer ring is attachable to the bowl to achieve different crimp diameters for a given die set. The die segments are mounted on the die plate for radial movement.
