Definitions

  • the present embodiments relate generally to systems and methods for forming a cable in an improved manner.
  • Roll formed cables may be formed using a variety of techniques.
  • wires of the cable may implement a central strand surrounded by one or more helically layered strands.
  • the cable may be made by twisting the strands of each layer about the central strand with a wire twisting machine.
  • the central strand may be surrounded by a second layer comprising four to eight helically formed strands, which in turn may be surrounded by a third layer comprising around 10 to 14 helically formed strands.
  • the number of layers may vary, in addition to the number of strands per layer, depending on the particular application and size of the cable being manufactured.
  • a single central strand may be omitted.
  • the innermost layer may comprises two to four strands that have cross-sectional shapes that when disposed adjacent to one another will form a configuration similar to a single circular strand.
  • the strands of the second layer of the cable when the strands of the second layer of the cable are helically wrapped around the first layer, the strands of the second layer will travel a greater distance, relative to the strands (or single strand) of the first layer, for any given longitudinal length of the cable.
  • Forming the first and second layers on common forming rolls at the same wire travel speed may require equipment or methods that adjust travel speed to ensure the strands of the second layer can travel the greater helical distance and properly be disposed about the first layer.
  • the cross-sectional shapes of one layer cannot be modified independently. In other words, if it becomes desirable to change the cross-sectional shape for strands of one of the first layer or the second layer, then an entire new set of forming rolls may be required to accommodate such change.

Movement of the plurality of rolls of the non-driven roll station occurs passively during travel of the one or more strands associated with the first layer of the cable.
  • the system further comprises a driven roll station having a plurality of rolls for forming a shape of one or more strands associated with a second layer of the cable. The plurality of rolls of the driven roll station are actively driven to effect movement and speed of the one or more strands associated with the second layer of the cable.
  • the first layer of the cable may be disposed radially inward relative to the second layer.
  • the driven roll station may be disposed upstream relative to the non-driven roll station.
  • the driven roll station may comprise a through hole for travel of the one or more strands associated with the first layer of the cable.
  • the one or more strands associated with the first layer may exit the non-driven roll station at a different speed relative to which the one or more strands associated with the second layer exit the driven roll station.
  • the one or more strands associated with the first layer may exit the non-driven roll station at a slower speed relative to which the one or more strands associated with the second layer exit the driven roll station.
  • the system may further comprise a lay plate having a plurality of recesses and a plurality of roller guides, wherein each of the plurality of recesses houses a corresponding roller guide, wherein each of the strands of the second layer of the cable are guided around a respective roller guide.
  • the lay plate may comprise a central aperture, disposed radially inwardly relative to the plurality of roller guides, wherein the one or more strands of the first layer are guided through the central aperture.
  • the non-driven roll station may comprise a housing that is coupled to the lay plate.
  • a first closing die may be disposed downstream of the non-driven roll station, wherein the first closing die is coupled to the lay plate using a mounting bracket, wherein the one or more strands associated with the first layer are passed through the first closing die.
  • a common closing die may be disposed downstream of the non-driven roll station, wherein the one or more strands associated with both the first and the second layers are passed through the common closing die.

  • the cable 10 comprises a first layer 12, which in this embodiment is an inner layer that comprises three strands 12a- 12c.
  • the cable 10 further comprises a second layer 14, which is generally disposed external to the first layer 12, and which in this embodiment comprises nine strands 14a-14i.
  • the cable 10 further comprises a third layer 16, which is generally disposed external to the second layer 14 and in this example comprises twelve strands, and further comprises a fourth layer 18 that is generally disposed external to the third layer 16 and in this example comprises sixteen strands. It is noted that some strands of the second layer 14, and the strands of the third and fourth layers 16 and 18, are not individually numbered to enhance illustrative purposes.
  • each individual layer 12, 14, 16 and 18 may comprises greater or fewer than the number of strands depicted in FIG. 1.
  • one or more layers 12, 14, 16 and 18 may be omitted, such as for example layer 18 and/or layer 16.
  • more than four layers may be provided, where such additional layers are disposed generally external to the fourth layer 18.
  • many possible combinations of cables, with a variable number of layers and strands within each layer may be formed using the system 20 described below.
  • the cross-sectional area of each of the individual strands may be selected depending on a particular desired shape or application of the cable 10.
  • the strands 12a- 12c of the inner layer 12 are depicted as having two generally flat inner surfaces coupled with a convexly curved exterior surface.
  • Such exemplary shape may be beneficial so that the generally flat inner surfaces of each of the strands 12a- 12c are disposed in close proximity to one another, as shown in FIG. 1 , and so that the convexly curved exterior surfaces collectively form a generally circular shape for abutting inner surfaces of the strands 14a-14i of the second layer 14.
  • the inner layer 12 comprises greater or fewer than three strands, then the cross-sectional shape and size of each individual strand may be different than what is depicted in FIG. 1.
  • the strands 14a-14i of the second layer 14 are helically wrapped around the strands 12a-12c of the first layer 12. Therefore, the strands 14a-14i travel a greater distance, relative to the strands 12a- 12c, for any given longitudinal length of the cable 10. In other words, because the strands 14a-14i of the second layer 14 are disposed radially outward relative to the strands 12a- 12c, the helical path spanning a wider radial distance is a longer path over the same actual longitudinal distance.
  • the strands of the third layer 16 are helically wrapped around the strands 14a- 14i of the second layer 14, and the strands of the third layer 16 travel a greater distance relative to the strands 14a-14i for any given longitudinal length of the cable 10.
  • the strands of the fourth layer 18 are helically wrapped around the strands of the third layer 16, and the strands of the fourth layer 18 travel a greater distance relative to the strands of the third layer 16 for any given longitudinal length of the cable 10.
  • the system 20 provides a novel approach to ensure smooth formation of such cable under these considerations.
  • FIG. 2 a perspective view of a first embodiment of the system 20 for forming a cable is shown and described.
  • the system 20 comprises a driven roll station 30, a non-driven roll station 50, a lay plate 70, an optional first closing die 80, and a common closing die 90.
  • FIG. 2 For illustrative purposes, it may be noted that in FIG. 2, only one strand 12a of the first layer 12 is depicted, and only one strand 14a of the second layer 14 is depicted. In contrast, in FIG. 7 below, each of strands 12a- 12c and some of the strands 14a-14i are depicted.
  • the driven roll station 30 is disposed upstream relative to the non-driven roll station 50 and the closing dies 80 and 90. Accordingly, strands travel from a direction that originates upstream of the driven roll station (i.e., left of station 30 in FIG. 2 and FIG. 7), then downstream towards the non-driven roll station 50 and the closing dies 80 and 90.
  • the non-driven roll station 50 may be positioned upstream relative to the driven roll station 30 while still achieving the same advantages of the present embodiments.
  • the driven roll station 30 comprises first and second rolls 32 and 38.
  • a driven roll station refers to the station having an ability to achieve actuation or rotation of the rolls within the station itself, e.g., via a motor or other actuator disposed within the station, or coupled in close proximity (e.g., being an adjacent part), that is capable of providing sufficient force to actuate the rolls of the station.
  • the plurality of rolls 32 and 38 of the driven roll station 30 are actively driven to effect movement and speed of the one or more strands 14a-14i associated with the second layer 14 of the cable 10.
  • the driven roll station 30 and the non-driven roll station 50 may comprise different shapes and configurations, with the non-driven roll station 50 comprising a reduced profile to yield a reduced footprint and multiple other advantages explained further below.
  • the first roll 32 of the first forming station 30 comprises first and second ends 32a and 32b, which are rotatable about a housing recess without the driven roll station 30.
  • the first roll 32 further comprises a plurality of forming grooves 34, and a through channel 35.
  • a first plurality of forming grooves 34 are disposed towards the first end 32a
  • a different plurality of forming grooves 34 are disposed towards the second end 32b
  • the through channel 35 is disposed in a generally central location between the forming grooves 34.
  • the second roll 38 may comprise generally symmetrical features relative to the first roll 32 (with a potential exception being different groove shapes to provide variable inner and outer cross-sections of a given strand).
  • the second roll 38 may be disposed vertically beneath the first roll 32 within the driven roll station 30, as shown in FIG. 2.
  • one of the plurality of forming grooves of the first roll 32, and an adjacent one of the plurality of forming grooves of the second roll 38 collectively are configured to form a cross-sectional shape of one of the strands 14a-14i of the second layer 14 of the cable 10.
  • a previously unformed wire strand 14a of the second layer 14 may be fed through the driven roll station 30 in the upstream to downstream direction, and as the strand 14a passes through a given forming groove 34 of the rolls 32 and 38, the cross-sectional shape of the strand 14a as shown in FIG. 1 may be achieved in accordance with the profile of the forming grooves 34.
  • the other strands 14b through 14i of the second layer 14 may be individually passed through grooves 34 of the rolls 32 and 38, such that the cross-sectional profiles of the strands 14a- 14i are formed at the same time within the driven roll station 30, using different grooves within the rolls 32 and 38.
  • the first roll 32 may comprise at least nine grooves 34 (to accommodate each of the strands 14a-14i), and the second roll 38 may similarly comprise at least nine grooves 34 that work in conjunction with respective grooves in the first roll 32.
  • the first roll 32 comprises a generally semi-circular through channel 35.
  • a generally symmetrical semi-circular through channel may be formed in the second roll 38.
  • the semi-circular through channels 35 of the first and second forming rolls 32 and 38, when placed in close proximity, may collectively form a generally circular through hole.
  • the strands 12a- 12c of the first layer 12 of the cable 10 may be passed through the through hole formed by the through channels 35 in the first and second rolls 32 and 38.
  • cross-sectional shapes of the strands 12a- 12c are not formed as the strands pass within the through channel 35.
  • the strands 12a- 12c of the first layer 12 are formed at the non-driven roll station 50, thereby providing advantages for the present system.
  • the first roll 52 comprises a central aperture 53 and a plurality of grooves 54, as best seen in FIGS. 5A-5B.
  • the first roll 52 may comprise three grooves 54a-54c, as shown in FIG. 5B. While three grooves are depicted the first roll 52, it will be appreciated that greater or fewer grooves may be provided.
  • the second roll 58 may comprise generally symmetrical features relative to the first roll 52 (with a potential exception being different groove shapes to provide variable inner and outer cross-sections of a given strand), and may be disposed adjacent to the first roll 52 within the non- driven roll station 50, as shown in FIGS. 2, 4 and 6A-6C.
  • one of the plurality of forming grooves of the first roll 52, and an adjacent one of the plurality of forming grooves of the second roll 58 collectively are configured to form a cross-sectional shape of one of the strands 12a- 12c of the first layer 12 of the cable 10.
  • a previously unformed wire strand 12a of the first layer 12 may be fed through the non-driven roll station 50 in the upstream to downstream direction, and as the strand 12a passes through the grooves 54a of the rolls 52 and 58, the cross-sectional shape of the strand 12a as shown in FIG. 1 may be achieved in accordance with the profile of the grooves 54a.
  • the other strands 12b and 12c of the second layer 14 may be individually passed through grooves 54b and 54c, respectively, of the rolls 52 and 58. Accordingly, the cross- sectional profiles of each of the strands 12a- 12c are formed at the same time within the non- driven roll station 50.
  • the non-driven roll station 50 does not have a motor or other actuator disposed within or adjacent the station itself, which differs from driven roll station 30. Therefore, the non-driven roll station 50 may comprise a significantly reduced profile relative to the driven roll station 30.
  • the forces required to pull the strands 12a-12c through the grooves within the rolls 52 and 58 of the non-driven roll station 50 may be provided by downstream equipment that exerts a relatively high pulling force upon the strands, taking into account friction that is expected during the forming process.
  • the non-driven roll station 50 may comprise a housing assembly 60, which generally maintains the relative positions of the first and second rolls 52 and 58, and permits rotational movement of the rolls during formation of the cross-sectional profile of the strands 12a- 12c of the first layer 12.
  • the housing assembly 60 comprises a first flanged region 61 a and a second flanged region 61b, each of which comprises one or more apertures 62 to facilitate mounting to the lay plate 70 of FIGS. 6A-6C, as explained further below.
  • the housing assembly 60 further comprises two axes 63, around which the central apertures 53 of the forming rolls 52 and 58 are disposed for rotational movement.
  • a shaft and bearings may be provided along the axes 63 to facilitate rotational movement of the forming rolls 52 and 58 around the axes 63.
  • the lay plate 70 comprises a mounting segment 71 having one or more grooves 72 that are adapted to be coupled to a base assembly 89 (shown in FIG. 2) to thereby hold the lay plate 70 in a desired location with respect to the system 20.
  • the lay plate 70 further comprises a guide segment 73, which in one embodiment may be integrally formed with the mounting segment 71 and disposed generally vertically above the mounting segment 71 , as depicted in FIGS. 2 and 6A-6C, although it is contemplated that the guide segment 73 may alternatively be disposed at the same height or vertically below the mounting segment 71.
  • the guide segment 73 comprises a generally circular shape having a front surface 74, a rear surface 75, and a central aperture 79.
  • the first and second flanged regions 61 a and 61b of the housing assembly 60 of the non-driven roll station 50 may be mounted to opposing regions of the front surface 74 of the guide segment 73 of the lay plate 70, as best seen in FIGS. 6A and 6B.
  • bolts may be secured through the apertures 62 in the first and second flanged regions 61 a and 61b, and may securely engage the front surface 74 of the lay plate 70.
  • first and second rolls 52 and 58 of the non-driven roll station 50 may be positioned within the central aperture 79 of the lay plate 70. Further, an entrance location 59 disposed between the first and second rolls 52 and 58, which is adapted to received the strands 12a- 12c of the first layer 12, may be positioned generally at the center of the aperture 79 of the lay plate 70, as depicted in FIGS. 6A-6B.
  • a plurality of recesses 76 may be formed in the guide segment 73 between the front and rear surfaces 74 and 75, as best seen in FIGS. 6B-6C.
  • the plurality of recesses 76 each may be sized to accommodate a respective roller guide 77.
  • the roller guides 77 may be mounted on individual shafts 78, such that each roller guide 77 is capable of circumferential movement around its respective shaft 78. In this manner, each of the roller guides 77 may rotationally move within its respective recess 76.
  • the roller guides 77 may comprise a concave outer surface that accommodates a portion of the strands 14a-14i of the second layer 14. As seen in FIG. 2, the strand 14a of the second layer 14 extends around the outer surface of its respective roller guide 77, at a location within the recess 76.
  • each roller guide 77 may orient a corresponding strand 14a- 14i of the second layer 14, providing circumferential spacing in a radially outward manner relative to the central aperture 79. Such circumferential and radial spacing of the strands 14a- 14i helps position the strands for downstream helical placement about the first layer 12.
  • the recesses 76 and roller guides 77 are not disposed evenly around the circumference of the lay plate 70 in FIGS. 6A-6C due to the intervening placement of the first and second flanged regions 61a and 61b of the housing 60 of the non-driven roll station 50.
  • four recesses 76 and roller guides 77 are disposed in relatively close proximity above the housing 60, while another four recesses 76 and roller guides 77 are disposed in relatively close proximity below the housing 60, such that the upper and lower recesses and roller guides are not directly adjacent.
  • the non-driven roll station 50 may be disposed at a location separate from the lay plate 70, in which case all of the recesses 76 and roller guides 77 may be evenly spaced about the perimeter of the guide segment 73 of the lay plate 70.
  • the first closing die 80 may be coupled to the rear surface 75 of the lay plate 70 using a mounting bracket 81.
  • the mounting bracket 81 comprises first and second arms 82 and 83, each having an upstream end coupled to the rear surface 75 by securing means 84, and further each having a downstream end coupled to the first closing die 80, as depicted in FIG. 6C.
  • the first and second arms 82 and 83 are configured to extend a sufficient longitudinal distance so that the strands 12a- 12c of the first layer 12, which may be formed in grooves 54a-54c a distance apart within the rolls 52 and 58, may meet up at the first closing die 80.
  • the first closing die 80 then orients the strands 12a-12c closely together and passes the collectively formed first layer 12 further downstream.
  • the first closing die 80 may comprise an interior surface that is slightly larger than an outer surface of the first layer 12, and may provide a desirable orientation while reducing unwanted twisting of the strands 12a- 12c.
  • the common closing die 90 then orients the strands 14a- 14i of the second layer 14 closely together around the exterior surface of the strands 12a- 12c of the first layer 12, and passes the collective bundle 15 comprising the first and second layers 12 and 14 further downstream.
  • the first closing die 80 may be omitted, and the common closing die 90 may simultaneously orient strands of both the first and second layers 12 and 14.
  • the collective bundle 15 comprising the first and second layers 12 and 14 is depicted at a location downstream of the common closing die 90.
  • An additional roll station 130 may be disposed downstream of the driven roll station 30, the non-driven roll station 50, the lay plate 70, and the closing dies 80 and 90.
  • Strands of the third layer 16 may be guided around these components, and directed to the additional roll station 130, which may comprise rollers that form the cross- sections shapes of the strands of the third layer 16.
  • the collective bundle 15 comprising the first and second layers 12 and 14 may pass within a through hole in the additional roll station 130.
  • the collective bundle 15 may pass through a central region of an additional lay plate 97, while the strands of the third layer 16 pass around guide rollers of the lay plate 97.
  • the lay plate 97 may be similar to the lay plate 70 described above, with a main exception that the non-driven roll station 50 is omitted from the central region of the lay plate 97.
  • the lay plate 97 guides the strands 16 in the proper orientation towards a third closing die 98, which then orients the strands of the third layer 16 closely together around the exterior surface of the strands 14a- 14i of the second layer 14, and passes the collective bundle 17 comprising the first, second and third layers 12, 14 and 16 further downstream.
  • the fourth layer 18 of the cable 10 may be formed, and secured around the perimeter of the third layer 16, in a manner similar as described above. It is noted that the depiction of roller guides 77 associated with the lay plate 70 and the lay plate 97 have been omitted for illustrative purposes only in FIG. 7 (to better depict the large number of strands and other components), but would be present in the manner depicted in FIGS. 2 and 6A-6C.
  • the present embodiments are capable of forming a cable 10 without requiring a driven roll station 30 corresponding to each layer of the cable 10. While the strands of the second layer 14 are formed using the driven roll station 30, the strands of the first layer 12 are formed using the non-driven roll station 50. This has the advantage of reducing the overall footprint of the system 20 by providing fewer large driven roll stations 30.
  • non-driven roll station 50 forming the first layer 12 is secured within the lay plate 70, which also serves to guide and orient the second layer 14, the overall footprint of the system 20 may be consolidated further by grouping components at the same location. While in this example the non-driven roll station 50 is shown secured to the lay plate 70, it will be appreciated that non-driven roll station 50 may be disposed at a stand-alone location relative to the lay plate 70, may be disposed within a dedicated passage formed in the driven roll station 30, or may be disposed upstream relative to the driven roll station 30, while achieving the same significant advantages.
  • the present embodiments allow for individual control of speed of the layers 12 and 14 of the cable 10.
  • the strands 14a- 14i of the second layer travel a greater distance, relative to the strands 12a- 12c, for any given longitudinal length of the cable 10.
  • the driven roll station 30 and the non-driven roll station 50 are separate and distinct, the strands 12a- 12c of the first layer 12 may be passed through the non-driven roll station at a first speed that is less than a second speed at which the strands 14a-14i of the second layer 14 are passed through the driven roll station 30.
  • Such different forming speeds would not be possible if both the first and second layers 12 and 14 were formed on common rolls. This achieves a significant advantage in that the strands of the second layer 14 may travel the greater distance helically at the greater speed, relative to the strands of the first layer 12.
  • the present embodiments allow for individual control of gaps at the different roll stations 30 and 50, to accommodate an array of cross-sectional shapes of the layers 12 and 14 of the cable 10.
  • the cross-sectional shapes of one layer cannot be modified independently, i.e., an entire new set of forming rolls is required.
  • independent control of roll gap is available to modify shapes for the first and second layers 12 and 14 separate of one another, simply by changing the roll gaps at the station 50 or the station 30, respectively.
  • the cable 10 may comprise any number of layers, and each layer may comprise any number of strands, without departing from the principles of the present embodiments.
  • the strands 12a-12c of the first layer 12 have been formed by the non-driven roll station 50, and the strands 14a- 14i of the second layer 14 have been formed by the driven roll station 30, in alternative embodiment the strands of the first layer 12 may be formed by a driven roll station while the strands of the second layer 14 may be formed by a non-driven roll station.
  • an optional wire break detector 99 may be disposed at any location along the system 20 with one or more sensors to detect strand breakages. If such breakage is detected, a machine shutdown may occur to avoid further issues. It will be appreciated that other sensors may be provided at desired intervals along the system 20.
