- 18. The assembly of claim 1, wherein the second portion of the assembly comprises a second pin attached to a bifurcate end of the segment.
- 19. The assembly of claim 18, wherein at least one end of the second pin comprises a tab for engaging a portion of the bifurcate end of the segment such that articulation of the second pin relative to the segment about the second axis is limited.
- 20. An apparatus for deforming a workpiece, comprising:
at least one segment for engaging the workpiece; at least one arm for actuating the segment; an assembly for articulating the arm relative to the segment, the assembly comprising:
a first pin defining a first axis of articulation, a second pin defining a second axis of articulation, wherein the first and second pins couple between the arm and the segment such that the arm articulates relative to segment about the first and second axes of articulation.
- 21. The apparatus of claim 20, wherein the first pin has a first end hingedly attached to the at least one arm.
- 22. The apparatus of claim 21, wherein the first end of the first pin defines a hole substantially transverse to the first axis of articulation and hingedly attached to the at least one arm by a hinge pin in the transverse hole.
- 23. The apparatus of claim 22, wherein the transverse hole is elongated along an axial length of the first pin.
- 24. The apparatus of claim 20, further comprising a cam member positioned between the at least one arm and the at least one segment, the cam member having a curved surface for engaging the at least one arm and having a flat surface for engaging the second pin.
- 25. The apparatus of claim 24, wherein the cam member is integrally attached on the first pin or is slideably positioned on the first pin.
- 26. The apparatus of claim 20, wherein the segment defines a pocket and wherein the second pin removably positions in the pocket of the segment.
- 27. The apparatus of claim 20, wherein the segment defines a holder and wherein the second pin is attached, to the holder of the segment.
- 28. The apparatus of claim 20, wherein the second pin defines a hole substantially transverse to the second axis of articulation, and wherein a distal end of the first pin is fixedly or removably positioned in the transverse hole of the second pin.
- 29. A crimping apparatus, comprising:
at least one segment for crimping; at least one arm for actuating the at least one segment; first means for articulating about a first axis of articulation; first means for coupling the first articulating means to the arm; second means for articulating about a second axis of articulation; second means for coupling the second articulating means to the segment; and means for coupling the first and second articulating means together.
- 30. The crimping apparatus of claim 30, wherein the first coupling means comprises means for hingedly attaching the first articulating means to the arm.
- 31. The crimping apparatus of claim 30, wherein the second coupling comprises means for rotatably attaching the second articulating means to the segment.
- 32. The crimping apparatus of claim 30, wherein the means for coupling the first and second articulating means together comprising means for removably and rotatably coupling the first and second articulating means together.
- 33. The crimping apparatus of claim 30, further comprising third means for articulating about a third axis of articulation.
- 34. The crimping apparatus of claim 30, further comprising means for substantially transferring pivoting motion of an end of the arm substantially perpendicular to a plane that is substantially parallel to the second axis of articulation.
- 35. The crimping apparatus of claim 30, wherein the means for coupling the first and second articulating means together further comprises means for biasing the coupling between the arm and the segment.
