ABSTRACT:
A crimping die is provided for use in a crimping machine for radially crimping the collar of a hose coupling onto the end of a hose. The crimping die includes a die assembly having a plurality of die segments and at least one unitary retention and separator band. The die segments are adapted for arrangement into a circular array about a central axis, with each of the die segments having a radially inner surface forming a section of a common collar bore about the central axis for receipt of the collar of the hose coupling. Each die segment includes a top surface having an arcuate groove formed therein. The groove has a predetermined cross-sectional configuration with an open upper end that is provided with a lesser width than the width of at least a portion of the groove below the upper end. The unitary retention and separator band is constructed of an elastomeric material and has a like plurality of die segment retaining portions and a plurality of spacer portions. Each retaining portion has a cross-sectional configuration that mates with and is adapted for receipt into the groove of a respective one of the segments for retaining the segments together. The spacer portions are spaced along the band for disposition between adjacent ones of the die segments and have a length to space the segments a predetermined distance apart when the die assembly is in a free state.
