Definitions

  • the present application is related to a first Provisional Application Serial No. 60/013,060 filed March 8, 1996 and to a second Provisional Application Serial No. 60/036,084 filed January 16, 1997.
  • the present invention relates to a crimper assembly or crimper machine for crimping a workpiece, for example, crimping a fitting ferrule to a hose.
  • Crimping assemblies or crimping machines for crimping fittings to hoses are well known in the art.
  • One such prior art crimper is disclosed in U.S. Patent No. 5,257,525.
  • Other types of crimping assemblies or crimping machines are shown in prior art patents Nos. 4,034,592; 4,034,593; 4,400,967; and 4,785,656.
  • the present crimper assembly is particularly useful in crimping hose fittings in the field. Sometimes it is necessary to connect, for example, a hose fitting ferrule to a flexible hose which is designed to carry gases. In this situation, it is important that the crimper assembly be capable of providing a tight sealed crimp which does not release gas to the atmosphere.
  • One problem in prior art crimper machines was the difficulty in disassembling the crimper assembly or crimper machine to quickly replace the die segments, when necessary. This is often necessary where various diameter fittings or fitting ferrules are being crimped and the dies or die segments must be quickly replaced.
  • One object of the present invention is to provide an improved crimper assembly which is readily disassembled for the interchange of the die sets.
  • the present invention is directed to a crimper machine or crimper assembly for crimping a workpiece, such as a hose fitting ferrule to a hose.
  • the crimping assembly includes a pair of tie rods having different diameters which mount a lower stationary die carriage and an upper moveable die carriage.
  • a central rod is mounted on the moveable carriage and extends through a press bar.
  • a driving force is applied to the central rod by either a cylinder or by an impact wrench to a screw, connected to the central rod.
  • Die retainer plates are attached adjacent receiving cavities defined by the carriages and include guide slots. Tongues are provided on flexible die set retainers which are positioned within the receiving cavities. When in the correct position, the tongues extend into the guide slots and hold the die set retainers in their correct position.
  • a spring biased disconnect plate is slidably attached to the tie rods adjacent the press bar. When the disconnect plate is moved to a disconnect position, the movable carriage can be moved along the tie rods for access to the flexible die set retainers and the die sets.

  • the movable die carriage 13 has spaced apart passageways 20 and 21 for slideably receiving the tie rods 18 and 19.
  • the passageway 21 being of a slightly larger diameter than the passageway 20. The difference in diameter of the passageways 20 and 21 and the corresponding tie rod diameters 18 and 19 ensure that when the slidable, moveable die carriage 13 is removed from the tie rods 18 and 19, for example, when the die sets are removed, the moveable die carriage 13 is not improperly reversed when it is repositioned on the tie rods 18 and 19.
  • a press bar 23 defines openings 24 and 25 which receive the upper ends of the tie rods 18 and 19.
  • the upper ends of the tie rods 18 and 19 define reduced diameter portions 26 and 27.
  • the press bar 23 also defines a central aperture 29 which receives a central rod 30.
  • the bottom of the central rod 30 has an attachment end 31 which is secured to the moveable die carriage 13 by roll pins 32.
  • the upper end of the central rod 30 is operatively connected to the rod of a cylinder 34.
  • the cylinder 34 is a hydraulic cylinder and is supplied by a hydraulic pump 35.
  • the central rod 30 is driven by an air cylinder (not shown) or by a screw as discussed subsequently.

  • the moveable die carriage 13 can then be removed from the tie rods 18 and 19. This operation is normally used when the die sets are changed.
  • the upper surface of the press bar 23 defines a pair of parallel slots 44 which receive springs 45.
  • One end of each of the springs is connected to the press bar 23 by pins 46 and the other end is connected to the disconnect plate 37 by pins 47.
  • the springs 45 act as a spring assembly which is operatively connected between the disconnect plate 37 and the press bar 23 to urge the disconnect plate 37 to the crimper assembly operating position wherein the first openings 39 and 40 within the disconnect plate 37 receive and are aligned with the reduced diameter portions 26 and 27 of the tie rods 18 and 19.
  • the disconnect plate 37 is slidably positioned on the press bar 23 by a plurality of cap screws 49 which extend through a plurality of longitudinally extending slots 50 in the disconnect plate 37 and are received in threaded openings 51 in the top of the press bar 23.
  • elastomeric bumpers 53 are mounted on the bottom of the press bar 23, as shown in Fig. 1. As the moveable die carriage moves upwardly when the central rod 30 is retracted, the moveable die carriage 13 can engage the bumpers 53.
