  • This invention relates generally to an apparatus for swaging couplings or the like to the end of a hose, wire, cable or the like, and more particularly to a hydraulically actuated swaging device.
  • a hand actuated device adapted to swage a coupling on the end of a hose is disclosed in US. Pat. No. 3,048,2l2.
  • This device has a ram slidably mounted on guide pins which can be moved downwardly by hand with a handle to exert pressure against a coupling and force it'into a die cavity.
  • Such a device satisfactorily swages a-coupling on the end of a hose.

  • Base 14 has a longitudinally extending bore or aperture 55 having an inner wall which tapers inwardly substantially parallel with the beveled lower ends of support members 10 and 10a.
  • a piston cylinder 15 composed of a cylindrical housing with ends 60 and 61 is disposed between support members 10 and 10a.
  • a first piston rod 17 has a first piston 16 mounted on its lower threaded end and secured thereto by nut 18.
  • Piston rod 17 passes through an opening in top 60 of cylinder 15 and is secured to top cross-bar 11 against longitudinal movement with a socket head cap screw.
  • a seal is provided in opening 60 about piston rod 17 to retain liquid under pressure in cylinder 15.
  • Cylinder 15 is free to move longitudinally over piston rod 17 Annular spaces 72 and 73 between bosses 70 and 71 and the cylindrical housing insure that ports 27 and 29 are not blocked when boss 70 and 71 bottom out against a piston.
  • a second piston rod 21 has an upper threaded end with a second piston 20 secured thereto by nut 22.
  • the lower end of piston rod 21 extends through a sealed opening in the bottom 61 of cylinder 15 which permits piston cylinder 15 to move longitudinally with respect to the piston rod 21.
  • the lower end of piston rod 21 is fastened to an intermediate cross-member 25 with a has a boss 19 which fits into an opening in the-under- FIG. 6 is a cross-section taken along the line 6-6 of FIG. 4; and
  • FIG. 7 is an enlarged, fragmentary, longitudinal section of the die and supporting frame in their positions illustrated in FIG. 2.
  • the apparatus provided by this invention is adapted to install any swage-on type coupling or fitting to any type of hose, wire or cable, including, wire braid hose, plastic hose, rubber hose and composite hose having a core and sheath of rubber or plastic such as nylon and an intermediate layer of fibrous reinforcing material, insulated wire or cable and the like.
  • a frame is composed of a pair of horizontally spaced, vertically extending rods or support members 10 and 10a having their threaded ends extending through bores in top cross-bar l1 and secured thereto by means of nuts 12 and 13 and having their lower ends side of cross-bar 25 immediately below the end of piston rod 21.
  • Spring plunger 26 extends into a notch in boss 19 to secure pusher 23 to cross-bar 25.
  • a first port 27 is positioned on the cylindrical housing of cylinder 15 between piston 16 and top 60.
  • a second port 28 is positioned on the cylindrical housing of cylinder is below piston 16 and above the uppermost position of piston 20.
  • a third port 29 is positioned on the cylindrical housing of cylinder 15 below second piston 20 and above bottom 61.
  • a T-type fitting 30 lies between a port 27 and a first high pressure hose 31 which leads to a hydraulic valve 62 which in turn is connected to pump 32 which withdraws liquid from reservoir 33.
  • Port 28 is provided with a suitable fitting and is connected through a second high pressure hose 34 to valve 62.
  • Port 29 is connected through a suitable fitting and a third high pressure hose 35 to T-fitting 30.
  • the internal diameters of hose 35 and of fittings 35a are sufficiently less than the opening through port 27 to require a greater pressure for passage of liquid therethrough than is required for liquid to flow through the opening of port 27.
  • a pair of horizontally spaced lift bars 36 and 36a are spaced outwardly from and extend longitudinally alongside of support members 10 and 10a respectively.
  • the upper ends of lift bars 36 and 36a are pivotally attached with nuts and bolts to brackets 37 and 38 respectively which are welded or otherwise firmly secured to the housing of cylinder 15.
  • the lower ends of lift bars 36 and 36a are bent inwardly to a position substantially parallel to the beveled lower ends of support members 10 and 10a.
  • the length of the inwardly bent portions 54 and 54a of lift bars 36 and 36a may vary with the length of the stroke of piston rod 21. In an apparatus in which cylinder moves downwardly about 2 inches, about 3% inches of the lower ends of lift bars 36 and 36a may be bent inwardly.
  • Brackets39 and 40 are bolted at one end to lift bars 36 and 36a adjacent the bent portions thereof.
  • Die support frames 41 and 42 are welded to the other ends of brackets 39 and 40.
  • Die frame 41 has a plurality of peripherally spaced fixed pins 43 and one detent pin 44.
  • Mounting frame 42 has similarly peripherally spaced fixed pins 45 and detent pin 46.
  • a valve handle 52 is moved to a position forward from neutral to set valve 62 so that it will direct liquid from pump 32 and reservoir 33 through hose 34 and port 28 into cylinder 15 and direct displaced liquid passing from cylinder 15 through port 27 and hose 31 to reservoir 33.
  • Valve handle 52 is moved to a position rearward to direct passage of 1 liquid under pressure through hose 31 into cylinder 15.and from cylinder 15 v through port 28 and hose 34 to reservoir 33.
  • a bracket 49 is welded or otherwise firmly secured at one end to cross-bar 25 and projects outwardly beyond lift bar 36a.
  • a lift rod 50 is attached at its lower end to a latch handle 51 and passes through a hole drilled near the end of bracket 49.
  • Latch handle 51 holds valve handle 52in its rearward position until the volume of liquid below piston is sufficient to raise piston 20, piston rod 21 and cross-bar to the point where bracket 49 engages collar 53 which is vertically adjustable on rod 50 to permit adjustment of the length of the stroke. Then, as collar 53 continues to move upwardly, latch handle 51 is lifted by rod 50 and .becomes disengaged from valve handle 52 permitting it to move back to a neutral position and close valve 62.
  • the swaging device may be supported by any suitable means such as by a jig or it may be mounted on a bench.
  • Die base 14 should extend outwardly from the edge of the bench top in order that lift bars 36 and 36a and die halves 47 and 47a may move to positions below die base 14.
  • Support 65 for reservoir 33 can be conveniently made of angle iron and drilled to provide for bolting support 65 of reservoir 33, pump 32 and the motor 74 to the surface of a bench. When support 65 lies against the horizontal surface of the bench, the longitudinal axis of the upright portion of the apparatus is tilted backwards.
  • a hose end 57 is inserted between stem or insert 57' and ferrule 59 of a coupling and the assembly is pushed through cavity 58 of the die until the threaded end 63 of the coupling is inserted in the cavity of pusher 23 as shown in FIGS. 2 and 7.
  • Valve handle 52 is moved to its forward position. This opens the valve for passage of liquid under pressure from pump 32 through hose 34 and port 28 into cylinder 15 between pistons 16 and 20 and for the displacement of liquid through port 27 and hose 31 back to reservoir 33.
  • cylinder 15 moves longitudinally from cross-bar 11 until it bottoms on piston 16. Since the passage of liquid through port 29 requires a greater pressure than passage of liquid through port 27,
  • lift bars 36 and 36a As the bent ends54 and 54a of lift bars 36 and 36a move below base 14 they are guided inwardly by ad justable guide members 56 and 56a permitting the lower portions of lift bars 36 and 36a to move to a position parallel with support members 10 and 10a as illustrated in FIG. 3. As lift bars 36 and 36a move inwardly, frames 41 and 42 and die halves 47 and 47a are moved together to the position shownin FIG. 3.
  • Valve handle 52 is now moved manually'to its position rearward where it is held by latch handle 51. At this position of valve handle 52, liquid is pumped through hose 31 and because there is less resistance to fluid flow through port 27 than through hose 35 and fittings 35a, the liquid passes into cylinder 15 through port 27. Port 28 is opened when the valve handle 52 is positioned rearwards so liquid may flow from between pistons 16 and 20 back to reservoir 33 through hose 34. As the volume of liquid above piston 16 increasesand the volume of liquid between pistons 16 and 20 decreases, cylinder 15 moves upwardly until it bottoms 7 against cross-bar 11.
  • hose 35 may be increased to increase the resistance to passage of liquid therethrough.
  • the most advantageous method of obtaining sequencing of cycles is to select a hose 35 and fittings 35a of less diameter than the opening in port 27 or to use a hose 35 of sufficient length to offer more resistance to fluid flow than port 27.
  • Pushers 23 may .be provided with various sizes of cavities to accommodate different sizes of fittings and quickly interchanged from one to the other by removing spring plunger 26 from the notch in the boss of the pusher.
  • the openings 60 and 61 through the walls of piston cylinder 15 must be sealed to prevent the loss of liquid about piston rods 17 and 21. Any conventional pressure seal may be used.
  • a rubber O-ring mounted in a suitable spring retainer clip may be inserted in the opening for this purpose.
  • Any suitable conventional hydraulic valve adapted to direct fluid in and out of the cylinder as described above may be used.
  • the four-way valve described and illustrated on page 251 of Oil Hydraulic Power by Walter Ernst, Second edition, published by McGraw Hill Book Company (1960) may be used. Hydraulic valves sold by Dukes Company Incorporated Schiller Park, Illinois as Series DV-020 and Series DV-03O control valves have been found to be particularly advantageous.
  • the lower ends of -support members 10 and ll la,.the lower ends of lift bars 36 and 36a and the inner wall of die receiving aperture 55 in die base 14 are all parallel with each other and slope inwardly at an angle of about 15 from perpendicular.
  • the angle can be greater or less than 7 15 depending upon the distance desired between the two die halves for insertion of the parts to be swaged and for removal of the swaged product therefrom.
  • a support for the die and a ram for pressing an article to be shaped into a cavity in the die means for sequentially hydraulically (1) moving the ram towards the die support while simultaneously actuating the die segments to form a die having a cavity therein and (2) pressing the article in the die cavity and shaping it to the configuration of the die cavity, and (3) hydraulically actuated means for lifting the ram from the shaped product while separating the die segments to release the resulting product from the die cavity.
