Abstract
Abstract A swaging tool comprising a duality of axially slotted, radially compressible, opposed dies having adjacent generally cylindrical surfaces defining an opening for receiving a workpiece, and outer surfaces including laterally flared side portions, said dies being movable toward each other and including recesses having outwardly flared side portions which urge the side portions of the dies inwardly as such movement takes place so that all portions of the dies are compressed equally, one of the diecarrying members being removable to allow independent association with a workpiece to be swaged.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
230 words
A swaging tool comprising a duality of dies, each of said dies including a plurality of substantially parallel elongated elements collectively having an inner surface defining a generally semicylindrical contour, and an outer surface having a central part made up of a plurality of said elements collectively defining a generally cylindrical segment and side parts flatter than said central part and flaring outwardly therefrom, said elements of each of said dies being spaced apart so as to provide a means for permitting radial compression thereof so as to reduce the radius of curvature of said inner surface, a member carrying each of said dies, each of said members including a surface adjacent said outer surface of the die carried thereby, said surface of each of said members including a central part defined by a generally cylindrical segment of smaller radius than that of said generally cylindrical segment of said central part of said outer surface of said die carried thereby, and having side parts flatter than said central part of said member and flaring outwardly therefrom, said side parts of said member engaging said side parts of said die carried thereby, said central part of each of said members being normally spaced from said central part of said die carried thereby, and means for moving said members relatively toward each other for compressing said dies and swaging a workpiece therebetween.
Claim 2
Dependent Claim
230 words
A swaging tool comprising a duality of dies, each of said dies including a plurality of substantially parallel elongated elements collectively having an inner surface defining a generally semicylindrical contour, and an outer surface having a central part made up of a plurality of said elements collectively defining a generally cylindrical segment and side parts flatter than said central part and flaring outwardly therefrom, said elements of each of said dies being spaced apart so as to provide a means for permitting radial compression thereof so as to reduce the radius of curvature of said inner surface, a member carrying each of said dies, each of said members including a surface adjacent said outer surface of the die carried thereby, said surface of each of said members including a central part defined by a generally cylindrical segment of smaller radius than that of said generally cylindrical segment of said central part of said outer surface of said die carried thereby, and having side parts flatter than said central part of said member and flaring outwardly therefrom, said side parts of said member engaging said side parts of said die carried thereby, said central part of each of said members being normally spaced from said central part of said die carried thereby, and means for moving said members relatively toward each other for compressing said dies and swaging a workpiece therebetween.
Claim 3
Dependent Claim
32 words
A device as recited in claim 1 in which said side parts of said outer surfaces of said dies are substantially flat surfaces tangent to said central parts of said outer surfaces.
Claim 4
Dependent Claim
51 words
A device as recited in claim 2 in which said side parts of said members are substantially flat surfaces tangent to said central parts of said members, said substantially flat surfaces of each of said members being substantially in complementary engagement with said substantially flat surfaces of the die carried thereby.
Claim 5
Dependent Claim
92 words
A device as recited in claim 3 in which, for said means for spacing said elements apart and permitting radial compression of said dies, each of said dies is a unitary member provided with a plurality of longitudinal slots therethrough, said slots including a plurality of first slots extending axially inwardly from one end of said die and stopping short of the opposite end of said die, and a plurality of second slots extending inwardly from said opposite end of said die and stOpping short of said one end of said die.
Claim 6
Dependent Claim
17 words
A device as recited in claim 4 in which said first slots are intermediate said second slots.
Claim 7
Dependent Claim
50 words
A device as recited in claim 5 in which, for said means for moving said members relatively toward each other, there is included power means for moving one of said members toward the other of said members, and means for holding said other member stationary relative to said power means.
Claim 8
Dependent Claim
45 words
A device as recited in claim 6 in which said means for holding said other member stationary is removable for permitting said other member and said die carried thereby to be separated from said power means and independently associated with a workpiece to be swaged.
Claim 9
Dependent Claim
25 words
A device as recited in claim 6 in which said other member is a yoke carrying one of said dies in the intermediate portion thereof.
Claim 10
Dependent Claim
43 words
A device as recited in claim 8 in which said means for holding said other member stationary includes interengaging abutment surfaces on said yoke and said power means, said abutment surfaces being disengageable, and means for normally preventing disengagement of said abutment surfaces.
Claim 11
Dependent Claim
51 words
A device as recited in claim 8 in which, for said means for holding said other member stationary, said power means includes an elongated member having a flange thereon, said yoke having opposed sidewalls having shoulders thereon engageable with said flange, and including means for holding said flange between said sidewalls.
Claim 12
Dependent Claim
58 words
A device as recited in claim 10 in which said means for holding said flange between said sidewalls includes a nut, said elongated member having threads thereon engaged by the threads of said nut, said nut having a recess receiving the ends of said yoke for preventing substantial lateral movement of said yoke relative to said elongated member.
Claim 13
Dependent Claim
47 words
A device as recited in claim 11 in which said elongated member is a hollow post, and in which said power means includes a power cylinder and a rod extending through said post for engagement with said one member remote from said intermediate portion of said yoke.
Claim 14
Dependent Claim
208 words
A swaging tool comprising a duality of dies, each of said dies being a unitary member having a plurality of slots alternately extending inwardly from its opposite ends so as to provide a plurality of substantially parallel elongated elements, said elements collectively defining an arcuate inner surface, said elements collectively defining an outer surface with an arcuate central part made up of a plurality of said elements, and side parts flatter than said central part and flaring outwardly therefrom, a carrying member for each of said dies, each of said carrying members including a surface adjacent said outer surface of the die carried thereby, said surface of each of said carrying members including an arcuate central part of greater curvature than that of said arcuate central part of said die carried thereby, and side parts flatter than said central part of said carrying member and flaring outwardly therefrom, said side parts of said carrying member engaging said side parts of said die carried thereby, said central part of each of said surfaces of said carrying members being normally spaced from said central part of said die carried thereby, and means for moving said carrying members relatively toward each other for compressing said dies and swaging a workpiece therebetween.
