Description

Technical Field

[0001] The present application relates to the technical field of stranding equipment, and in particular to a stranding tube shaft and a stranding machine. Background Art

[0002] The stranding shaft is used in the stranding machine to drive the wire storage reel and the wing tension control mechanism to rotate synchronously, so as to achieve the twisting of the wires released from the wire storage reel with the center line passing through the center of the stranding shaft to form a cable. Before twisting, the existing wires need to be pulled out of the wire storage reel and extended from the front end of the stranding shaft along the inside of the stranding shaft. Traditional stranding shafts generally adopt a fully hollow structure, which will cause multiple wires to be easily mixed when inserted, making it inconvenient to distinguish them at the front end of the stranding shaft. At the same time, during the rotation of the stranding shaft, the wires may come into contact with the inside of the stranding shaft due to the action of centrifugal force, causing wear, thereby affecting the stranding quality of the cable.

DETAILED DESCRIPTION

[0026] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0027] In the description of this application, it should be noted that for directional words, such as the terms "center", "horizontal", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and so on, the directions and positional relationships indicated are based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific scope of protection of this application.

[0028] It should be noted that the terms "first", "second", etc. in the description and claims of this application are used to distinguish similar objects and do not necessarily describe a specific order or sequence.

[0029] The terms "comprising" and "having" in the description and claims of this application, and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device comprising a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0030] One preferred embodiment of this application is as Figure 1 and Figure 2 shown. A twisted body tube shaft includes an outer tube 11 and a core tube 12. The outer tube 1 can be rotatably installed on a frame (not shown), so as to drive the wire 210 to be twisted to form a cable by the rotation of the outer tube 1. The core tube 12 can be installed in the first inner cavity 110 of the outer tube 11. A plurality of baffles 121 are provided on the front side wall of the core tube 12 along the wire outlet direction, and the plurality of baffles 121 are equally spaced along the circumferential direction. Thus, when the core tube 12 is installed in the first inner cavity 110 of the outer tube 11, the adjacent baffles 121 can cooperate with the side wall of the first inner cavity 110 to form a guiding area for the wire 210 to outlet.

[0031] It should be known that the traditional transmission tube shaft is generally of a hollow structure. After multiple wires 210 enter the inside of the transmission tube shaft, they will be entangled with each other and need to be carefully distinguished to be sorted out. In this embodiment, by separately setting the twisted body tube shaft 1 into the outer tube 11 and the core tube 12, and providing the baffles 121 on the front side wall of the core tube 12 to form a guiding area, the number and position of the guiding areas are equal to the number of wires 210 required for twisting. By setting the guiding area, each wire 210 can be distinguished, so as to ensure that the wires 210 do not get entangled with each other, and there is no need for re-identification, and the rapid installation of the wire 210 can be realized.

[0032] It should also be known that the number of formed guiding areas, that is, the number of baffles 121, is related to the number of wires 210 required for cable twisting. For example Figure 1 shown, if the number of wires 210 required for twisting the cable is six, then the required number of guiding areas is also six, and the number of corresponding baffles 121 is set to six.

[0033] In this embodiment, as Figure 4 , Figure 7 and Figure 8As shown, multiple groups of support components 13 are axially installed on the side wall of the first inner cavity 110. Each group of support components 13 is circumferentially located in each guiding area, and the support components 13 can be in press-fit with the wire 210. Thus, when the stranding tube shaft 1 drives the wire 210 to rotate, the wire 210 contacts and presses against the support components 13 under the action of centrifugal force, and thus the wire 210 can be effectively isolated from the side wall of the first inner cavity 110, ensuring that the wire 210 will not be worn or the wear will be reduced during the stranding process.

[0034] It can be understood that the number of support components 13 in each group corresponds to the number of guiding areas, which can support the wire 210 in each guiding area. The number of groups of support components 13 is related to the length of the stranding tube shaft 1. The longer the length of the stranding tube shaft 1, the more groups of support components 13 need to be set; for example Figure 4 As shown, two groups of support components 13 can be set.

[0035] It should be known that, as Figure 1 shown, a wire reel 3 is generally installed at the front part of the stranding tube shaft 1. The wire 210 extending from the stranding tube shaft 1 can be lifted to a certain height through the wire reel 3 to ensure that the wire 210 can be stranded with the center line 220 at an appropriate angle. Therefore, the wire 210 will be lifted upward after extending out of the stranding tube shaft 1, which may cause the wire 210 to rub against the front end of the stranding tube shaft 1. Therefore, when setting the support components 13 in this embodiment, one group of support components 13 can be set at the front end of the outer tube 11, so that through the support of the support components 13, the wire 210 can be led out without contact with the stranding tube shaft 1.

[0036] Specifically, as Figures 1 to 3 shown, the core tube 12 is detachably and fixedly connected to the front end of the outer tube 11 through a flange 122 provided at the front end. The flange 122 is provided with a plurality of wire outlet openings 1220 in the circumferential direction, and the wire outlet edges 1220 extend radially along the flange 122. The wire 210 passing through the support components 13 in the guiding area can extend along the wire outlet openings 1220 to the wire reel 3. Due to the support of the support components 13 at the front end position, the wire 210 can be spaced from the outer end in the radial direction of the wire outlet openings 1220 when passing through the wire outlet openings 1220, thereby avoiding wear with the outer end of the wire outlet openings 1220.

[0037] In this embodiment, the support component 13 can adopt an elastic structure, so that the supporting force of the support component 13 on the wire 210 can be adaptively adjusted. It should be noted that the tension force of the wire 210 during the stranding process changes at all times. If the support component 13 with a rigid structure is used, when the tension force of the wire 210 becomes smaller, that is, when the wire 210 becomes loose, the support component 13 may become loose from the wire 210. Therefore, in this embodiment, by elastically setting the support component 13, the support component 13 can follow the change of the tension force of the wire 210, so as to ensure that the support component 13 is always in contact and cooperation with the wire 210.

[0038] In this embodiment, there are various specific structures of the support component 13 that can achieve the above functions. For the convenience of understanding, one of the structures will be described in detail below. As Figures 5 to 8 shown, the side wall of the first inner cavity 110 is provided with a mounting plate 112 corresponding to the support component 13 in the circumferential direction, and a sliding groove 1120 extending radially along the first inner cavity 110 is provided on the mounting plate 112. The support component 13 includes a pressing part and an elastic member. The pressing part is slidably matched with the sliding groove 1120, and the pressing part can be in extrusion cooperation with the wire 210; the elastic member is installed between the pressing part and the side wall of the first inner cavity 110.

[0039] It can be understood that generally, the smaller the friction force between the pressing part and the wire 210 is, the better, so that the wear of the wire 210 can be effectively reduced. In order to reduce wear, the pressing part and the wire 210 can be in rolling cooperation.

[0040] Specifically, as Figures 5 to 8 shown, the mounting plates 112 are arranged in pairs, and an installation groove 113 is formed between the two mounting plates 112; the pressing part includes a pressing wheel 131 and a pair of sliders 133; the two sliders 133 are correspondingly slidably installed in the sliding grooves 1120 on the two mounting plates 112; the pressing wheel 131 is rotatably installed on the two sliders 133 through a rotating shaft 132; the elastic members are a pair and are correspondingly installed between the sliders 133 and the side wall of the first inner cavity 110.

[0041] It should be noted that the specific structure and working principle of the elastic member are well-known technologies to those skilled in the art. Common elastic members include springs 134 and elastic sheets, etc. In this embodiment, a spring 134 is preferably used. The spring 134 always balances with the tension force of the wire 210 through its own elastic force. When the tension force of the wire 210 decreases, the pressing wheel 131 can slide along the sliding groove 1120 towards the center position of the first inner cavity 110 under the elastic force of the spring 134, so as to ensure that the wire 210 with a reduced tension force can still be in contact with the pressing wheel 131.

[0042] It can be understood that when the spring 134 is connected to the slider 133, since the width of the slider 133 may not meet the installation requirements, a connecting plate 1331 can be provided on the side of the slider 133 in the direction away from the pressing wheel 131, and the spring 134 can be installed between the connecting plate 1331 and the side wall of the first inner cavity 110.

[0043] Another aspect of the present application provides a stranding machine. As Figure 1 shown, one preferred embodiment includes the above-mentioned stranding tube shaft 1, wing tension control mechanism 4 and wire reel 3; the wing tension control mechanism 4 is installed in the middle of the stranding tube shaft 1, and the wire reel 3 is installed at the front end of the stranding tube shaft 1; the wing tension control mechanism 4 can pay off the tensioned wire 210 into the guiding area, and then the wire 210 passes through the first inner cavity 110 and is stranded with the center line 220 passing through the second inner cavity 120 of the core tube 12.

[0044] Specifically, as Figure 4 and Figure 8 shown, a plurality of opening grooves 111 are provided in the middle of the outer tube 11 along the circumferential direction; the wing tension control mechanism 4 is detachably and fixedly installed on the outer tube 11 through the wheel body 41 and faces the opening grooves 111. A plurality of extending parts 411 passing through the opening grooves 111 and extending to the corresponding guiding areas of the first inner cavity 110 are arranged inside the wheel body 41; a guide wheel 42 is rotatably installed in the extending parts 411, and the guide wheel 42 can guide the wire 210 released by the wing tension control mechanism 4 into the guiding area, so that the wire 210 entering the guiding area does not interfere with the side wall of the first inner cavity 110 of the outer tube 11.

Those skilled in the art should understand that the present application is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present application. Without departing from the spirit and scope of the present application, the present application will have various changes and improvements, and these changes and improvements all fall within the scope of the present application claimed.
