Definitions

  • the principal object of the invention is to provide a multiple draft wire drawing machine which may operate continuously to produce very long lengths of wire.
  • the dies are stationary, while the blocks that pull the wire through the successive dies rotate.
  • the wire leaving the last die of the series of dies is wound up on the last block.
  • the entire machine Whenthe last block is full, the entire machine must be stopped so that the wire on the last block may be removed therefrom.
  • the machine must be periodically stopped to remove the accumulated wire. This is damaging to production.
  • a stationary or dead block In another type of wire drawing machine, a stationary or dead block is used. Here the wire is drawn through a die rotating about the dead block. The wire accumulating on the dead block is discharged therefrom con tinuously. Numerous means are available to receive the wire discharged from the dead block so that production may run continuously until the wire being fed to the rotating die is exhausted. However, it is well understood that it is impossible to put a succession of dead blocks and their accompanying rotating dies in series to produce multiple drafting on a single wire in the same manner in which multiple drafting of wire is accomplished through the use of the live rotating blocks and stationary dies.
  • a new and novel combination of dies and blocks is presented by which part of the drafting is done with stationary dies and live blocks and the final part of the drafting is done by a rotating die from which the finished wire is deposited on a dead block and removed therefrom in conventional manner.
  • the wire drawing is accomplished by the use of one stationary die and one live block and by a rotating die and one dead block to produce a minimum of two drafts in a small and relativelysimple machine.
  • additional drafts through the use of two or more stationary dies and associated live blocks may precede the' final drafting which is accomplished by the rotating die and the dead .block. a
  • the invention also includes mechanism designed to insure that the length of wire being fed to the dead block from the last live block will always be adequate to meet the demands of the dead block, thereby precluding'the development of such tension in the wire on its way to the rotating die that might cause breakage.
  • FIG. 1 is a plan view of the machine which accomplishes two drafts
  • FIG. 2 is an end elevation of the machine looking from the left of FIG. 1;
  • FIG. 3 is an end elevation of the machine looking from the right of FIG. 1;
  • FIG. 4 is a fragmentary enlarged vertical section taken 3,177,690 Patented Apr. 13, 1965 and live blocks prior to the last draft by the rotating die and dead block;
  • FIG. 7 is an end elevational view of FIG. 6 looking from the left.
  • the wire W is drawn through die 2 by the horizontal live block 4, after which it is carried by suitable mechanism to a rotating die 6, through which it is drawn and wound on horizontal dead block 8, from which it peels off to be collected on the frame 10. Since frame 10 can be periodically removed and a new collecting frame substituted therefor, it is obvious that wire can be drawn through the two dies 2 and 6 continuously without stopping the machine.
  • a block in wire drawing machines is said to be a horizontal block when its axis is horizontal.
  • the blocks are vertical.
  • the present machine is not to be limited to horizontal blocks.
  • a supporting structure 12 of sutficient strength and generally in the nature of a hollow sheet metal housing carries a motor 14 and a gear box and shaft support 16.
  • the coupled motor shaft 26 extends vertically therefrom, entering the lower wall of gear box 16.
  • the gear box is bolted by bolts 30 to a vertical panel 28 which is an integral part of housing 12.
  • the shaft 26 carries a worm 32 which meshes with a relatively large helical gear 34 which is mounted on and keyed to a shaft as.
  • cooling fins 37 may be used on the gear box, if desired.
  • Shaft 36 extends horizontally through the oppositely disposed vertical side walls of gear box 16 and is rotationally supported by bearings 38 and 40. Thus, when motor 14 is in operation, shaft 36 will revolve.
  • the gearing is arranged so that shaft as, as viewed in FIG. 2, revolves counterclockwise.
  • a block 4 On the left end of shaft 36 is mounted a block 4, which is in tl e form of a cylindrical drum flanged at its sides.
  • the wire W after passing through die 2, is wound for a few turns about block 4. It then leaves the top of block 4 to pass around a grooved sheave 42 whose axis 44 is set diagonally in a bracket 45 secured to the side wall of housing 12.
  • the discharging lower edge of sheave 42 directs wire W to a second smaller sheave 46 whose vertical axis 47 is mounted on a supporting bracket 18. Both the die 2 and sheave 46 are provided with-adjusting means for correct positioning.
  • Shaft 36 is drilled axially to provide a. bore 5%) therethrough, and thisaxial opening is aligned with sheave 46 so that wire W leaving sheave 46 may pass directly into and through shaft 36.
  • sheave 60 having its lower end adjacent sheave 57.
  • Two other sheaves 62 and 6d are suitably mounted in aligned but canted position on plate 54, as can be seen in FIGS. 1 and 4.
  • Sheave 62 has one side aligned with the outer end of tube 619.
  • a die support 66 is fastened to the face of plate 54 and carries the die 6.
  • the wire W may leave bore 50 by passing around sheave 57, thence radially outward through tube 60, around sheaves 62 and 64, and through die 6. After a few turns around block 8, the wire W leaves the block and passes under and over a series of four grooved casting rolls 6%, 70, 72 and 74.
  • the block is in the form of a slightly tapered circular drum having a flange 76 around its inner end and closed on its outer end by face plate 77.
  • the face plate is rigidly secured on a short tubular shaft '73 which in turn is supported by two sets of bearings 86 and 82 carried by the outer end of shaft 36.
  • bearings 8t and 82 are tapered to prevent axial movement of shaft 78( The bearings 80 and 82 are secured against dislodgement by a nut 86 which in turn is covered by a plate 84 fastened on the end of shaft 78.
  • Dead block 8 is held against rotation by structure that also serves the additional function of carrying off and collecting the Wire as it is continuously dislodged from the outer side of the dead block by the new wire accumulating on the block adjacent flange 76.
  • This structure can be seen best in FIGS. 1, 3 and 5.
  • a ring 87 To the outer side of face plate 77 of block 8 is welded, or otherwise secured in a slightly eccentric position, a ring 87. Ring 37 has rigidly fastened thereto four strong rods 88, 9t), 92 and 94. These rods extend away from face plate 77, paralleling the axis of shaft 36 for a short distance, after which they turn to the left, as viewed in FIG. 1, to make connection with a ring 96 at positions 90 degrees apart.
  • rod 88 is secured to ring 96 at 8%; rod 90 is secured at 99; rod 92 at '92; and rod 94 at 24.
  • These four rods and ring 96 collectively act as a lever arm attached to tthe dead block so that any tendency of the dead block 8 to rotate clockwise with shaft 36, as viewed in FIG. 3, maybe prevented by supporting the ring 96 against downward movement. Such downward movement of ring 96 is prevented by placing thereunder a wire collecting frame 98.
  • the upper end of frame 9% is slightly larger thanring 96, the latter resting on the curved upper shoulders of the inverted U-shaped members that constitute the frame.
  • These members at their lowerends are fastened to a base plate 1% which acts as the collect ing surface for the wire as it comes down the frame after having left the dead block. The general behavior of the.
  • the relative diameters of blocks 4 and 3 can be calculated so that the amount of wire leaving block 4 will be just the right amount called for by die 6 as it is drawn therethrough by dead block 8. This, however, is a very close calculation, and therefore in order to insure against breakage of the wire through possible failure of block 4 to deliver wire at the rate required to die 6, in a preferred embodiment, the diameter of block 4 may be made slightly in excess of the theoretical required diameter. This results in wire W being delivered to die 6 slightly in excess of the requirement. Consequently, slack will develop in wire W between block 4 and die 6.
  • the machine may run continuously to produce two drafts of the wire, one at die 2 and the other at die 6, and the finished wire convolutions falling on the collecting frame 98 may be removed periodically with a new empty'frar'ne '98 being substituted for the full frame.
