Definitions

  • a wire preforming assembly is fixedly mounted on a circular turntable having thereon a plurality of bobbins dispersed in an array to provide a plurality of wires to the assembly equally spaced around its periphery.
  • the assembly and the turntable are coaxially aligned with and relatively rotating about a longitudinally advancing, mandrelled hose.
  • the wires are being directed to the hose by the preforming assembly so that the hose pulls the wires with uniform equal tension and causes them to be simultaneously wrapped thereon in side-by-side parallel helical convolutions.
  • the wire is directed in a helical path around the surface of a preforming tube of the assembly and is bent toward the hose as it is being wound thereon. The bending imparts a characteristic to the wire which causes it to naturally retain the desired helical shape around the hose.
  • the high pressure hose may include an inner hose, several layers of armouring which are separated by protective tape, and an outer protective covering.
  • the several layers of armouring are usually in the form of pairs of windings in opposite directions to counter-balance any twisting or bending effect that winding in only one direction might impart to the hose.
  • a number of means have heretofore been employed to wind a plurality of wires on the inner hose by relative rotation of the respective sources of the wires about the hose. Longitudinally advancing the hose with respect to the sources of the wires continuously presents an unwrapped region of the hose at which the windings may be formed. It has been found that the winding can be accomplished by the described relative movement and that whether the sources of the wire or the hose should be fixed or moving is generally determined by other considerations other than the specific act of forming the windings of the hose.
  • the preforming devices such as those disclosed in U.S. Pat. Nos. 3,183,583, 3,187,494, and 3,357,456, have generally included a predetermined number of wirereceiving holes and wire-guiding surfaces for reverse bending of the wire in a region of the wire remote from the point at which it is applied to the inner hose.
  • any preforming device that institutes a deliberate deformation of the wire at a location remote from the hose can, because of the relative rotation, result in the wire being applied to the hose at an orientation which not only fails to follow the shape of the hose but might even have added resistance to it.
  • wire-receiving holes of the prior preforming devices tend to provide the desirable function of properly and evenly spacing the wire about the periphery of the hose to insure side-by-side alignment during winding.
  • a predetermined number of wire-receiving holes presupposes a predetermined number of wires if even spacing is to be maintained and thereby prevents a variation in the number of wires which different size hoses might require.
  • the time required for initially setting up the winding machines utilizing preforming apparatus that includes these wire-receiving holes is largely determined by the time required for each wire to be threaded through its respective wire-receiving hole.
  • the preforming devices previously employed in wire wrapping machines have not been readily adaptable to wire wrap hoses having different diameters or to allow variations in the number of wires utilized.
  • a preferred preforming assembly preforms wire being wound on an elongated member.
  • the wire is supplied from a source which is relatively rotated about and relatively displaced along the longitudinal axis of the elongated member to cause the wire to bewound on the elongated member in a helical shape.
  • the preforming assembly includes means for guiding the wire along a substantially helical path coaxially aligned with the elongated member and having a diameter greater than the diameter of the helical shape and means for bending the wire toward the elongated member as it leaves the helical path through a curved path having a radius less than the effective radius of the helical shape.
  • FIG. 1 is a sectional side view of the preferred wire preforming assembly including various features of the invention.
  • FIG. 2 is a view like that of FIG. 1 exploded to Show the preforming region.
  • FIG. 3 is a view of the preforming assembly as seen along line 33 of FIG. 2.
  • FIG. 4 is a view of the wire as seen along line 4-4 of FIG. 3.
  • FIG. 5 is a view of the wire as seen along line 5-5 of FIG. 2.
  • the preferred preforming assembly is fixedly mounted on a wire supply turntable 12 which, in the preferred configuration, rotates about a hose work product 14 in a clock-wise direction when viewed from the right.
  • the turntable 12 may be one of a number of types associated with spiral winders known to those skilled in the wire wrapping art, such as the ROCKWELL WSW-III Precision Wire Spiral Winder.
  • the winder is oriented so that the turntable 12 is coaxially aligned with the hose work product 14 along a common central axis 16.
  • the hose work product 14 is pulled, in the preferred configuration, to the left as indicated by the arrow A, without any rotation about its axis 16.
  • a caterpillar extractor like the ROCKWELL I-Ieavy-Duty Caterpillar Haul-Off or the type disclosed in US. Pat. No. 3,183,583.
  • the wire supply is rotated and the hose work product is pulled longitudinally with respect to the wire supply, it is the relative motion therebetween which is essential for the wire-wrapping.
  • the wire With the above-described relative motion established so that each wire source and the hose work product move in a generally helical path with respect to each other, the wire will be laid in a helical shape about the hose work product.
  • the diameter of the helical shape is of course established by that of the hose work product and the pitch of the helical shape is determined by the length of relative longitudinal movement for each revolution about this known diameter.
  • this invention it is not the purpose of this invention to establish the helical shape of the wire about the hose work product, but to preform the wire being so wound such that the internal forces within the wire established by the preforming will cause the wire to generally assume this helical shape even if it were not supported by the hose work product. If the wire is not preformed, the wire will have internal resilience which will tend to cause it to change its pitch and diameter and unwind from its contracting helical shape about the hose work product.
  • the preforming assembly 10 includes a forward frame and a rearward frame 22, respectively, having a hollow hub portion 24 and 26 coaxially aligned with the axis 16. Further, each frame and 22, respectively, includes several spokes 28 and 30 by which the preforming assembly 10 is fixedly mounted on the turntable 12 by post 31 and to which other elements of the preforming assembly 10 are secured.
  • Each wire 18, only one of which is shown in FIG. 1, is suplied from a bobbin 32 on the turntable 12 and is directed between the frames 20 and 22 to the hose work product 14 with other wires 18 to be simultaneously wrapped thereon in side-by-side parallel helical convolutions as seen at 34.
  • the typical hose work product 14 shown in FIG. 1 includes a central mandrel 36, an inner hose 38, a set of windings 40, and insulating tape 42.
  • a mandrel 36 is often placed within the inner hose 38 because the pulling force by the work product 14 required to wind and form the wires 18 could cause it to collapse without the support of the mandrel 36.
  • the mandrel 36 is removed from the finished hose.
  • the set of windings 40 is formed by rotation in the opposite direction from that for forming windings 34 and the insulating tape 42 is wound therebetween for the reasons discussed hereinabove.
  • each wire In the preforming apparatus 10, it is desirable to cause each wire to be guided along a generally helical path having a diameter greater than that of the hose work product 14.
  • a first gathering ring 44 is mounted on the rearward frame 22 by a bolt 46 at each spoke 30. Since the bobbins 32 are located at various radii on the turntable 12, the first gathering ring 44 includes a gradually curved surface 47 over which each wire 18 must pass so that they may all be directed toward the interior of the preforming assembly 10 at the same approach angle.
  • a second gathering ring 48 which also has a gradually curved surface 50 is mounted on the forward frame 20 by bolts 51 and generally faces toward the surface 47 of the first gathering ring 44.
  • the second gathering ring 48 has a smaller diameter than the first gathering ring 44 so that the wires 18 can be equally spiraled from their bobbins 32 toward the region between the hubs 24, 26 of the forward frame 20 and rearward frame 22.
  • a preforming tube 52 is centrally mounted at the hub 26 of the rearward frame 22 to extend forwardly toward the frame 20 in region within its hub 24.
  • the preforming tube 52 is intended to provide a surface about which the wire 18 can be directed in a generally helical path as discussed above.
  • the preforming tube 52 has a rearward portion 54 slidably engaged with the center of the hub 26. Each end of the rearward portion 54 is threaded so that an adjustment nut 56 may be turned for accurate longitudinal positioning of the tube 52 with respect to the rearward frame 22 and, because the longitudinal displacement between the frames 20 and 22 is fixed, with respect to the forward frame 20.
  • the periphery of the adjusting nut 56 is marked for an accurate indication of the position of the preforming tube 52 and a locking nut 58 acting on the opposite side of frame 22 insures that the tube 52 will be maintained in the set position. The significance of the adjustments of the tube 52 will also be discussed in detail hereinbelow.
  • the wire 18 As the wire 18 gradually curves round the surface 50 of the second gathering ring 48, it is naturally wound about a forward portion 60 of the preforming tube 52 by the pulling effect of the hose work product 14.
  • the wire 18 is not shown in FIG. 1 to have the generally helical path that actually exists about the tube 52 so that its total path to the hose work product 14 from the bobbin 32 may be shown.
  • a floating collar 62 is mounted within the hub 24 of the forward frame 20 to closely encircle the forward portion 60 of the tube 52.
  • the thickness of a space 63 between the floating collar 62 and the forward portion '60 of the tube 52 and the thickness of the wire 18 are exaggerated in FIG. 1 for ease of demonstration.
  • the space 63 is defined by the inside diameter of the collar 62 and the outside diameter of the forward portion 60 and is sufficiently close to the diameter of the wire 18 to insure that the wires are not doubled around the surface of the forward portion 60 and are all lying in parallel helical paths thereon.
  • the floating feature of the collar 62 allows uniform spacing 63 between the collar 62 and the forward portion 60 to insure that the wire will be evenly pulled therethrough.
  • the wire 18 As the wire 18 is pulled from the surface of the forward portion 60, it passes over a preforming edge 64 of the tube 52 toward the hose work product 14.
  • the hose work product 14 with the wires wrapped thereon then moves through a support bushing 66 secured at the hub 24 of the forward frame 20.
  • the bushing 66 is selected to conform to the size of hose work product for sliding contact therebetween to insure that the hose work product is maintained centrally aligned with the preforming assembly 10.
  • a retaining cap 68 is threadedly secured to the hub 24 of the forward frame to allow different support bushings to be easily installed to provide support for work products having different diameters.
  • FIGS. 25 are presented to allow a detailed description of the preforming feature which imparts to the wire a characteristic which results in improved windings for the hose work product 14.
  • the preferred preforming tube 52 has an outside diameter at the forward portion 60 of about 3 /2 inches.
  • the preforming edge 64 is rounded to curve inwardly from the outside surface of the forward portion 60 with a radius of about /s of an inch.
  • a preforming tube having these dimensions has been effectively used for winding wire with a 0.012 inch diameter or a hose work product having diameters ranging between /s of an inch and 3 inches.
  • the hose work product 14 shown in the Figures has a diameter of about 2% inches.
  • the particular wire 18 shown follows a generally helical path 70 around the inside surface of the forward portion 60 of the preforming tube 52 to the preforming edge 64 at the top of the tube 52.
  • the helical path 70 is established for each wire 18 during winding so that the only relative motion between the surface of the forward portion 60 and the wire 18 occurs as the wire 18 moves longitudinally along the established path 70.
  • the wire 18 is bent over the preforming edge 64 as it is pulled from the helical path 70 toward the hose work product 14.
  • the wire 18 makes initial contact with the hose work product 14 at 72 to join the other wires to form the helical convolutions 34 with a helical shape 74 predetermined by the relative motion described hereinabove.
  • the deflecting lip 76 may not be needed to insure proper bending of the wire 18 at the edge 64. Therefore, its significance will be discussed later in a discussion of preforming wire for hose work products having relatively small diameters.
  • the preforming tube 52 is longitudinally adjusted toward the deflecting lip 76 of the floating collar 62. Causing wire 18 to be contacted by the deflecting lip 76 allows finer control of the bending while providing the smaller radius R The angle and extension of the deflecting lip 76 is selected to insure that it will not extend sufficiently into the path of the wire 18 to cause the wire 18 to be reversely bent around the lip 76. It should be apparent that, although in the preferred preforming assembly 10 the preforming tube 52 is mounted for longitudinal movement with respect to the deflecting lip 76, the same desired relative movement could be obtained by an alternative means which allows for movement of the collar 62 toward the preforming tube 52.
  • the preferred preforming assembly 10 provides besides that of general alignment of the helical path and deformation through the radius smaller than the predetermined effective radius of the helical shape.
  • the natural spacing of the wires about the preforming tube 52 allows the preforming assembly 10 to be set-up in a relatively short time.
  • the preforming tube 52 is initially withdrawn from the area of the floating collar 62 as the wire ends are secured to the hose work product. Several revolutions of the wires about the hose work product cause the wire to begin spiraling from the bobbins. Having generally established the spacing in this manner, the preforming tube 52 is moved longitudinally for insertion into the floating collar 62.
  • the wires are individually positioned so that they do not cross or lie on top of each other.
  • the tube 52 may then be received within the collar 62 to maintain the wires in their relative positions.
  • the tube 52 is properly adjusted for preforming, the evenly spaced helical paths will be automatically established by the winding.
  • Another aspect of the preforming assembly eliminates an adjustment which is often required for other preforming devices.
  • a force When wire is deformed, a force must be applied at opposite sides of the area of deformation.
  • One force is provided by the pulling of the hose work product during winding but the other force is often substantially provided by a braking action on the bobbins.
  • Individually adjusting the braking on the bobbins is critical and time consuming.
  • the second force at the preforming edge is primarily provided by the sliding friction along the helical path. The slding friction is substantially equal on all of the wires so that critical individual adjustments of the bobbins are not required.
  • a method for winding wire on an elongated member comprising:
  • a preforming assembly capable of preforming wire being wound on a hose work product, said wire being supplied from a source being relatively rotated about and relatively displaced along the longitudinal axis of said hose work product to cause said wire to be wound on said hose work product in a helical shape, said preforming assembly comprising:

  • said wire capable of being deformed about said preforming edge through a curved path as said wire is drawn toward said hose work product from said helical path
  • said curved path having a radius less than the effective radius of the effective curve of said helical shape.
  • a preforming assembly capable of preforming a plurality of wires being wound in side-by-side convolutions on a hose work product, said wires being supplied from a plurality of bobbins mounted in an array about a support table as said support table is being relatively rotated about and relatively displaced along the longitudinal axis of said hose work product to cause each said wire to be wound on said hose work product in a helical shape, said preforming assembly comprising:
  • a preforming tube mounted at a first end on said support structure for extension away from said table in a direction for alignment with said longitudinal axis
  • said preforming tube having an opening for receiving said hose work product therethrough and a cylindrical outside surface which is coaxially aligned with said hose work product received within said opening and has a diameter greater than the diameter of said helical shape
