[0043] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0044] like Figures 1 to 3 As shown, the utility model provides a wire drum frame 1 of a wire stranding machine, including a frame body 10, a wire drum 20, a wire drum positioning member 30, a wire drum locking member 40, a hysteresis device 50 and a pulley assembly 60, wherein the hysteresis device 50 is connected to the frame body 10 via a mounting seat 70.

[0045] Among them, Figure 3 As shown, the wire drum positioning member 30 and the wire drum locking member 40 are relatively arranged on two opposite wall surfaces of the frame 10, and the wire drum 20 is connected between the wire drum positioning member 30 and the wire drum locking member 40. The wire drum locking member 40 can move along the axial direction of the wire drum 20 relative to the frame 10 and axially limit the wire drum 20. Specifically, as Figure 1 As shown, the pay-off drum 20 is positioned on the frame 10 by the drum positioning member 30, and is axially limited by the drum locking member 40 coaxially arranged on the frame 10 relative to the drum positioning member 30, so as to realize the assembly of the pay-off drum 20 and the frame 10 and ensure that the pay-off drum 20 is subjected to less mechanical resistance after being clamped. Figure 7 As shown, the outer diameter of the full reel of the pay-off reel 20 is D, and the diameter of the empty reel is d.

[0046] Among them, Figures 1 to 3 As shown, the pulley assembly 60 includes a first pulley 61, a second pulley 62, a synchronous belt 63 and a tensioning mechanism 64 for tensioning the synchronous belt 63. The synchronous belt 63 passes through the tensioning mechanism 64 and is sleeved on the first pulley 61 and the second pulley 62. One of the first pulley 61 and the second pulley 62 is sleeved on the wire drum positioning member 30 and is arranged between the pay-off drum 20 and the wall of the frame 10, that is, one of the first pulley 61 and the second pulley 62 and the pay-off drum 20 are sleeved on the wire drum positioning member 30 in sequence; the other of the first pulley 61 and the second pulley 62 is sleeved on the output shaft of the hysteresis device 50; the tensioning mechanism 64 is connected to the frame 10, To achieve a better tensioning effect, the tensioning mechanism 64 is arranged between the first pulley 61 and the second pulley 62. To facilitate the tensioning operation of the synchronous belt 63, the tensioning mechanism 64 and the wire drum positioning member 30 are arranged on the same wall surface of the frame 10; one of the first pulley 61 and the second pulley 62 has at least two pulley disks with different diameters, and the width of the other of the first pulley 61 and the second pulley 62 is not less than the sum of the widths of the at least two pulley disks; the synchronous belt 63 can be translated from one of the at least two pulley disks to the other of the at least two pulley disks along the axial direction of the output shaft of the hysteresis device 50 as a whole, and the synchronous belt 63 will not be separated from the tensioning mechanism 64. By limiting the relationship between the pulley widths, in the process of translating the synchronous belt 63 to change the transmission ratio of the pulley assembly 60, the synchronous belt 63 can still be completely sleeved outside the first pulley 61 and the second pulley 62 without being disengaged from the axial direction. In this embodiment, in order to allow the synchronous belt 63 to translate without separating from the tensioning mechanism 64 and to ensure the stable operation of the pulley assembly 60, along the axial direction of the output shaft of the hysteresis device 50, the length of the tensioning portion of the tensioning mechanism 64 for the synchronous belt 63 to pass through is not less than the sum of the widths of at least two pulley discs. Of course, the tensioning mechanism 64 can also ensure the stable operation of the pulley assembly 60 by moving relative to the frame 10 along the axial direction of the output shaft of the hysteresis device 50, and the utility model does not impose any restrictions on this.

[0047] Specifically, the first pulley 61 may have multiple pulley disks with different diameters, the second pulley 62 may have only one pulley disk, the width of the second pulley 62 (the width of the only single pulley disk on the second pulley 62) may not be less than the sum of the widths of the multiple pulley disks of the first pulley 61, the synchronous belt 63 may be translated as a whole along the axial direction of the output shaft of the hysteresis device 50 from one of the multiple pulley disks of the first pulley 61 to any other of the multiple pulley disks, and the synchronous belt 63 may be tensioned by the tensioning mechanism 64 to achieve the change in the transmission ratio of the pulley assembly 60 The second pulley 62 may have multiple pulley disks with different diameters, the first pulley 61 may have only one pulley disk, the width of the first pulley 61 (the width of the only single pulley disk on the first pulley 61) may not be less than the sum of the widths of the multiple pulley disks of the second pulley 62, the synchronous belt 63 may be translated from one of the multiple pulley disks of the second pulley 62 to any other of the multiple pulley disks along the axial direction of the output shaft of the hysteresis device 50, and the synchronous belt 63 may be tensioned by the tensioning mechanism 64 to change the transmission ratio of the pulley assembly 60. In order to prevent end face friction damage, there is a gap greater than zero between two adjacent pulley disks on the pulleys with multiple pulley disks in the first pulley 61 and the second pulley 62. Preferably, the width of the pulley with only a single pulley disk in the first pulley 61 and the second pulley 62 (the width of the only single pulley disk) is equal to the sum of the widths of the multiple pulley disks and the sum of the gaps between two adjacent pulley disks. Of course, it is also possible that one of the first pulley 61 and the second pulley 62 has a plurality of pulley discs with different diameters, and the other of the first pulley 61 and the second pulley 62 has a plurality of pulley discs with the same diameter. Along the bandwidth direction of the synchronous belt 63, the width of each pulley disc on the pulley with the plurality of pulley discs with different diameters and the width of each pulley disc on the pulley with the plurality of pulley discs with the same diameter are equal one by one, and the gap between two adjacent pulley discs on the first pulley 61 and the gap between two adjacent pulley discs on the second pulley 62 are also equal.

[0048] The wire drum frame 1 of the stranding machine provided by the utility model makes the pulley assembly 60 have different transmission ratios by translating the synchronous belt 63 onto the pulleys with different diameter ratios, thereby covering the tension range required for the production of finished cables of various specifications, and then realizing the production of finished cables of various specifications and large span tension through one production line.

[0049] According to an embodiment of the present invention, the frame 10 has a mounting plate 11, the mounting plate 11 is connected to the frame 10, and the mounting plate 11 is connected to a mounting seat 70 for mounting the hysteresis device 50. Specifically, as Figure 1 and Figure 3As shown, a mounting plate 11 for mounting a mounting seat 70 for mounting a hysteresis device 50 is connected between two walls of the frame 10 on which a wire drum positioning member 30 and a wire drum locking member 40 are respectively provided, and the output shaft of the hysteresis device 50 is suspended near one side of the wall of the frame 10 on which the wire drum positioning member 30 is provided.

[0050] According to an embodiment of the present invention, the wire drum rack 1 of the wire stranding machine further includes a bracket 80, which is disposed below the wire pay-off drum 20 along the gravity direction, and the bracket 80 is connected to the frame 10. Specifically, Figure 2 and Figure 3 As shown, the wire drum frame 1 of the stranding machine also includes two brackets 80 arranged below the wire drum 20 along the direction of gravity, and the brackets 80 are connected between two opposite walls of the frame body 10 where the wire drum positioning member 30 and the wire drum locking member 40 are respectively arranged, and the distance between the two brackets 80 is between the empty drum diameter and the full drum outer diameter of the wire drum 20, so as to support the wire drum 20 when the wire drum 20 accidentally falls off.

[0051] According to one embodiment of the present utility model, Figure 3 As shown, the first pulley 61 is connected to the wire drum positioning member 30, the second pulley 62 is connected to the output shaft of the hysteresis device 50, and the second pulley 62 has a first pulley disc 621 and a second pulley disc 622. The first pulley disc 621 and the second pulley disc 622 are sequentially arranged along the axial direction of the output shaft of the hysteresis device 50, and there is a gap greater than zero between the first pulley disc 621 and the second pulley disc 622. By setting the gap between the first pulley disc 621 and the second pulley disc 622, the first pulley disc 621 and the second pulley disc 622 are prevented from being damaged due to end surface friction. In this embodiment, the pulley assembly 60 meets the requirement of changing the transmission ratio by translating the synchronous belt 63 through two pulleys with different diameters sequentially arranged in the axial direction of the output shaft of the hysteresis device 50.

[0052] According to one embodiment of the present utility model, Figures 4 to 6 As shown, the first pulley 61, the first pulley disc 621 and the second pulley disc 622 are all provided with a baffle 65 for preventing the synchronous belt 63 from axially disengaging. Figures 4 to 6 As shown, in order to prevent the synchronous belt 63 from axial movement and axial separation, baffles 65 are provided on the first pulley 61, the first pulley disc 621 and the second pulley disc 622, wherein baffles 65 are provided at both ends of the first pulley 61 and the first pulley disc 621, and a baffle 65 is provided at the end of the second pulley disc 622 away from the first pulley disc 621.

[0053] According to an embodiment of the present invention, the length of the tensioning portion of the tensioning mechanism 64 for tensioning the synchronous belt 63 is not less than the sum of the widths of at least two pulleys, and the length direction of the tensioning portion is the same as the width direction of the synchronous belt 63. Specifically, Figure 1 and Figure 3 As shown, along the bandwidth direction of the synchronous belt 63, the length of the tensioning part of the tensioning mechanism 64 is not less than the sum of the widths of at least two pulley discs. In this embodiment, the length of the tensioning part of the tensioning mechanism 64 is consistent with the width of the first pulley 61.

[0054] According to an embodiment of the present invention, mounting holes 12 are symmetrically arranged on two opposite walls of the frame 10, and the axial direction of the mounting holes 12 is vertical to the axial direction of the pay-off reel 20. Specifically, Figure 1 and Figure 2 As shown, mounting holes 12 are symmetrically arranged on two opposite wall surfaces of the frame body 10 which are perpendicular to the axial direction of the pay-off drum 20 , and the drum frame 1 can be assembled to the stranding machine through the mounting holes 12 .

For details, please refer to the specific description of the above implementation scheme, and this application will not go into details here.

[0057] According to one embodiment of the present utility model, Figure 8 As shown, the stranding machine also includes a frame, an auxiliary support 2, a mounting plate 3, a stranding head 4, a main shaft 5, and a driving device 6 for driving the main shaft 5 to rotate. The main shaft 5 is mounted on the frame through the auxiliary support 2, the mounting plate 3 is sleeved on the main shaft 5 and fixedly connected to the main shaft 5, at least one wire drum rack 1 is mounted on the mounting plate 3, the axial direction of the wire drum 20 on the wire drum rack 1 is vertical to the axial direction of the main shaft 5, and the stranding head 4 is arranged on the frame along the axial direction of the main shaft 5. Among them, the mounting plate 3 is provided with a mounting shaft that matches the mounting hole 12 of the wire drum rack 1. In this embodiment, the wire drum rack 1 is connected to the stranding machine through two mounting plates 3 sleeved on the main shaft 5 at intervals.

[0058] According to one embodiment of the present utility model, Figure 8 As shown, the stranding machine comprises a plurality of bobbin racks 1 , which are arranged at intervals along the circumferential direction of the mounting plate 3 .

[0060] Step S1: Install the pay-off frame 7, the stranding machine, the traction machine 8, and the take-up frame 9 on the production line in sequence along the output direction of the finished cable;

[0061] Step S2: determining the transmission ratio of the pulley assembly 60 according to the tension requirement of the finished cable;

[0062] Step S3: Loosen the tensioning mechanism 64, translate the synchronous belt 63 to the pulley plate covering the above transmission ratio, and tighten the tensioning mechanism 64.

The finished cable reaches the take-up rack 9 under the traction of the traction machine 8, and the take-up rack 9 completes the winding of the finished cable.

[0064] The tension of the finished cable is formed by the superposition of the wire-reeling pulling force of the wire-reeling device and the back-acting force of the hysteresis device 50 (without considering the friction resistance), and its calculation formula is: F = M / L (M is the rated torque of the hysteresis device 50, L is the radius of the full or empty reel, that is, D / 2 or d / 2), M and L are fixed values, and different tensions F need to be obtained through different transmission ratios; Assume that the rated torque of the hysteresis device 50 is 9N.m, and the wire reel is 20 full. The outer diameter D=800mm, the empty disk diameter d=400mm, and the cable tension F can be controlled between 22.5N and 45N; further, it is assumed that: the transmission ratio of the second pulley disc 622 and the first pulley 61 is 1:10; the transmission ratio of the first pulley disc 621 and the first pulley 61 is 1:5; the cable tension F range can meet 225N~450N or 112.5N~225N; the choice of the above transmission ratio can be selected according to the process requirements of different finished cables.
