Abstract
Abstract A crimping machine has a rockable hydraulic cylinder which in a force transmitting position drives a die segment assembly into a tapered cavity to force the assembly to contract radially for crimping the socket of a fitting onto the end of a hose. The die segment assembly is a unitary chain of linked die segments which may befed into and removed from the die cavity in a serial manner to avoid obstructions. A floating die separator with axial projections engages angular surfaces on the bottom of the die segments to position the segments prior to crimping in a circular array which is equally circumferentially and radially outwardly spaced.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
169 words
A crimper assembly for crimping the socket of a hose fitting onto a hose end within a die block having a tapered bore therein,comprising a plurality of die segments for crimping the socket of a hose fitting, said die segments having an outer surface conforming to the bore of said die block and an inner surface for crimping said hose fitting, means connecting adjacent die segments; for limited relative movement to facilitate placement and removal of said die segments from said die block, said die segments being positioned in said die block in a circular array to encircle the socket of a hose fitting positioned therein, a die separator supporting said die segments in said die block in a first position therein for receipt of said hose fitting, said die separator engaging each of said die segments to position them in a symmetrical and spaced circular array, and means for urging said die segments simultaneously into said die block with said outer surface in engagement with said tapered bore.
Claim 2
Dependent Claim
169 words
A crimper assembly for crimping the socket of a hose fitting onto a hose end within a die block having a tapered bore therein,comprising a plurality of die segments for crimping the socket of a hose fitting, said die segments having an outer surface conforming to the bore of said die block and an inner surface for crimping said hose fitting, means connecting adjacent die segments; for limited relative movement to facilitate placement and removal of said die segments from said die block, said die segments being positioned in said die block in a circular array to encircle the socket of a hose fitting positioned therein, a die separator supporting said die segments in said die block in a first position therein for receipt of said hose fitting, said die separator engaging each of said die segments to position them in a symmetrical and spaced circular array, and means for urging said die segments simultaneously into said die block with said outer surface in engagement with said tapered bore.
Claim 3
Dependent Claim
37 words
The crimper assembly set forth in claim 1 wherein all of said die segments are secured by said connecting means to form a die segment assembly movable as a unit into and out of said die block.
Claim 4
Dependent Claim
63 words
The crimper assembly set forth in claim 2 wherein said die segment assembly is a die segment chain having first, last and intermediate die segments, said first die segment being separate from said last die segment so that said die segment chain may be placed in or removed from said die block without intersection of the central axis of said tapered bore therein.
Claim 5
Dependent Claim
61 words
4 . The crimper assembly set forth in claim 2 wherein said die. segment assembly is a die segment chain having one die segment free of connection to a second die segment whereby said first and second die segments and all die segments intervening between said first and second die segments may be positioned or removed from said die block, seriatim.
Claim 6
Dependent Claim
38 words
5 . The crimper assembly set forth in claim 3 or claim 4 wherein said die segment assembly comprises eight die segments, six of said die segments being joined by said connecting means to two adjacent die segments.
Claim 7
Dependent Claim
38 words
The crimper assembly set forth in any preceding claim wherein each said die segment includes an angled surface on the bottom portion thereof engageable with said die separator for camming said die segment relative to said die separator.
Claim 8
Dependent Claim
37 words
The crimper assembly set forth in claim 6 wherein said angled surface is-angled circumferentially and said die separator includes angled surfaces thereon cooperative with said angled surface of said die segments to cam said die segments circumferentially.
Claim 9
Dependent Claim
29 words
The crimper assembly set forth in claim 7 wherein said angled surfaces on said die separator are equally spaced to cam said die segments into equally spaced circumferential positions.
Claim 10
Dependent Claim
61 words
The crimper assembly set forth in claim 6, 7 or 8 wherein said angled surface on each said die segment is angled radially inwardly and upwardly so that each said die segment is cammed outwardly into engagement with the surface of said die block forming said tapered bore, to urge said die segments into outwardly spaced positions relative to one another.
Claim 11
Dependent Claim
28 words
The crimper assembly set forth in claim 7 or 8 wherein angled surfaces on said die segments and said die separator comprise vee-shape surfaces which interengage each other.
Claim 12
Dependent Claim
42 words
The crimper assembly set forth in any one of claims 6-10 further including spring means mounting said die separator to said die block for movement relative thereto. said die separator being movable with said die segments in response to said urging means.
Claim 13
Dependent Claim
100 words
The crimper assembly set forth in any preceding c?aim wherein said urging means ccmprises a hydraulic actuator reciprocable toward and away from said die block and a pusher plate disposed between said actuator and said d i e segments for evenly distributing the force of said actuator, said pusher plate being engageable with said die block to provide an end limit position thereof and having a recess therein in engagement with said di e segments to provide an end limit position of said die segments in said die block and thus determine the end crimp diameter of said die segments.
Claim 14
Dependent Claim
100 words
The crimper assembly set forth in any preceding c?aim wherein said urging means ccmprises a hydraulic actuator reciprocable toward and away from said die block and a pusher plate disposed between said actuator and said d i e segments for evenly distributing the force of said actuator, said pusher plate being engageable with said die block to provide an end limit position thereof and having a recess therein in engagement with said di e segments to provide an end limit position of said die segments in said die block and thus determine the end crimp diameter of said die segments.
Claim 15
Dependent Claim
46 words
The crimper assembly set forth in claim 12 wherein said hydraulic actuator is mounted for pivotal movement away from said die block to provide additional clearance for removal of said die segments, said pusher plate and hose fittings from the tapered bore of said die block.
