Description

Technical Field

[0001] This utility model relates to the field of dynamic cable production equipment, specifically a dynamic cable forming and branching device. Background Technology

[0002] During the production of dynamic cables, to ensure the structural strength of the core layer in the umbilical cable and avoid problems such as collapse and deformation, the numerous core wires in the core layer are twisted together, and the gaps between the core wires are filled to ensure that the core layer is twisted into a full and stable bundle. Dynamic cables contain various types of core wires, including electrical unit core wires and optical unit core wires, and the specifications of these core wires are also different. During the gap filling process, circular filler strips cannot guarantee sufficient filling; therefore, the structure of the filler strips is mostly irregular.

[0003] In traditional wire splitters, only a circular wire splitting hole is simply machined on the wire splitter to allow the irregular filler strip to pass through. However, during the stranding process, the irregular filler strip will deflect, causing it to fail to fill at the original filling angle, resulting in poor quality of the core wire layer after stranding. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a dynamic cable forming and splitting device that prevents irregularly shaped filler strips from deflecting during the twisting process.

[0005] The technical solution adopted by this utility model to solve the above problems is as follows: a dynamic cable forming and splitting device, comprising a body, the body including a large splitting plate and a small splitting plate. When the core wire layers of the dynamic cable are stranded into a bundle, the multiple core wires and filler strips in the dynamic cable first pass through the large splitting plate, and then through the small splitting plate. The large splitting plate is provided with large core wire holes equal to the number of core wires and large filler strip limiting holes equal to the number of filler strips. The small splitting plate is provided with small core wire holes equal to the number of core wires and small filler strip limiting holes equal to the number of filler strips. The large filler strip limiting holes... The perforated holes and small filler strip limiting holes are used to prevent the filler strips from deflecting during twisting. Each core wire passes through a corresponding large core wire hole and a small core wire hole, and each filler strip passes through a corresponding large filler strip limiting hole and a small filler strip limiting hole. The distance between the large core wire hole and the center of the large splitter plate is greater than the distance between the small core wire hole and the center of the small splitter plate. The distance between the large filler strip limiting hole and the center of the large splitter plate is greater than the distance between the small filler strip limiting hole and the center of the small splitter plate. The large splitter plate and the small splitter plate are coaxially arranged.

[0006] Compared with the prior art, the advantages of this utility model are as follows: During the core wire layer stranding process, by sequentially passing through the large and small splitter plates, and the design of large core wire holes, small core wire holes, large filler strip limiting holes, and small filler strip limiting holes, the multiple core wires and multiple filler strips are orderly reduced in diameter, which can avoid interference between the core wires and filler strips and ensure the accuracy of the position of the core wires and filler strips during stranding. The design of large and small filler strip limiting holes can prevent the filler strips from deflecting during the diameter reduction stranding process, thereby ensuring the stability of the filler strip stranding and ensuring the stranding quality of the core wire layer.

[0007] As an improvement of this utility model, the large and small splitter plates are longitudinally distributed. Through this improvement, the longitudinal stranding can reduce the influence of gravity on the stranding quality of the core wire and filler strip, which helps to improve the stranding quality of the core wire layer.

[0008] As an improvement of this utility model, the large wire splitter plate and the small wire splitter plate are fixedly connected by multiple connecting rods. The multiple connecting rods are evenly arrayed along the circumference of the small wire splitter plate. The distance between the connecting rod and the center of the small wire splitter plate is simultaneously less than the distance between the small core wire hole and the center of the small wire splitter plate, and the distance between the small filler strip limiting hole and the center of the small wire splitter plate. Through this improvement, the distance between the large wire splitter plate and the small wire splitter plate is guaranteed, thereby ensuring the diameter reduction ratio between the large wire splitter plate and the small wire splitter plate, and ensuring the stability of the stranded diameter reduction.

[0009] As an improvement of this utility model, both ends of the connecting rod are provided with connecting threads. One of the small and large branch plates is provided with a threaded hole for threaded fixed connection with one end of the connecting rod, and the other of the small and large branch plates is provided with a through hole for connection with the other end of the connecting rod. A nut for threaded connection with the other end of the connecting rod is provided at the end of the through hole near the small and large branch plates. Through this improvement, the connecting rod is fixedly connected to the large and small branch plates. At the same time, when using the same connecting rod, the distance between the large and small branch plates can be adjusted by using the fixed position between the other connecting rod and the through hole, thereby adjusting the diameter reduction ratio and increasing the adaptability of the dynamic cable forming and branching device in dynamic cables of different specifications.

[0010] As an improvement of this utility model, the large wire splitter plate is provided with a connecting plate for fixed connection with the connecting rod. The connection angle between the connecting plate and the large wire splitter plate is adjustable. Through this improvement, during the stranding and diameter reduction process of the core wire layer, the core wire and filler strip between the large wire splitter plate and the small wire splitter plate can be slightly deflected according to the stranding direction, thereby reducing the stranding angle difference between the small wire splitter plate and the core wire layer bundle, so as to reduce the bending angle when the core wire and filler strip are separated from the small wire splitter plate, which helps to reduce the probability of damage when the core wire and filler strip pass through the dynamic cable bundling and splitting device.

[0011] As an improvement of this utility model, the connecting plate is circular, and a mounting groove for mounting the connecting plate is provided on the axis of the large dividing plate. When the connecting plate and the large dividing plate are not fixed, the connecting plate is rotatably connected in the mounting groove. Through this improvement, the coaxiality between the large dividing plate and the small dividing plate is still guaranteed under the design of the connecting plate.

[0012] As an improvement of this utility model, the mounting groove has a plurality of fixing holes evenly arrayed in the circumferential direction, and the connecting plate has a plurality of arc-shaped grooves with the same radius as the fixing holes in the circumferential direction. The connecting plate and the large dividing plate are fixedly connected by fasteners passing through the arc-shaped grooves and fixing holes. Through this improvement, the connection angle between the connecting plate and the large dividing plate can be adjusted and fixedly connected.

[0013] As an improvement of this utility model, the size of the large filler strip limiting hole is larger than the size of the small filler strip limiting hole. The large filler strip limiting hole is located on the large insert, and the large insert is detachably connected to the large branching plate. The small filler strip limiting hole is located on the small insert, and the small insert is detachably connected to the small branching plate. Through this improvement, during the stranding and diameter reduction process, the design that the size of the large filler strip limiting hole is larger than the size of the small filler strip limiting hole can better constrain the deflection of the filler strip and improve the stranding quality. Through the detachable design of the large and small inserts, the corresponding large and small inserts can be replaced according to different filler strip shapes, improving the adaptability of the dynamic cable forming and branching device.

[0014] As an improvement of this utility model, both the large and small inserts are provided with flanges at their ends. The large insert is fixedly connected to the large splitter plate via an interference fit, and the small insert is fixedly connected to the small splitter plate via an interference fit. This improvement enables the fixed installation of the large insert on the large splitter plate and the small insert on the small splitter plate. Furthermore, because the dimensions of the large and small filler strip limiting holes are larger than the dimensions of the filler strip, the filler strip will not directly cause the large insert to detach from the large splitter plate or the small insert to detach from the small splitter plate during the guiding process. The flange design facilitates the installation and disassembly of the large and small inserts. During installation, the large insert will not be directly embedded into the large splitter plate, and the small insert will not be directly embedded into the interior of the small splitter plate. During disassembly, the large and small inserts have stress-bearing areas that facilitate disassembly using tools.

[0015] As an improvement of this utility model, the small core wire hole is set with an opening on the side away from the center of the small splitter plate. With this improvement, since the core wire is circular, there is no need for positioning and no need to worry about deflection. The structure of the small core wire hole can be simplified into a groove, which makes it easier for the core wire to be placed into the small core wire hole. It can also reduce the diameter of the small splitter plate and reduce the cost of the small splitter plate. Attached Figure Description

[0022] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0023] like Figure 1-2 As shown, a dynamic cable bundling device includes a main body, which includes a large splitter plate 1 and a small splitter plate 2. When the core layers of the dynamic cable 3 are twisted into a bundle, the multiple core wires and filler strips 3.3 in the dynamic cable 3 first pass through the large splitter plate 1 and then through the small splitter plate 2. The multiple core wires in the dynamic cable 3 include three electrical unit core wires 3.1 and three optical unit core wires 3.2. The filler strips 3.3 include six strips. The large splitter plate 1 is provided with six large core wire holes 1.1 and six large filler strip limiting holes 1.2. The small splitter plate 2 is provided with six small core wire holes 2.1 and six small filler strip limiting holes 2.2. The large filler strip limiting holes 1.2 and... The small filler strip limiting hole 2.2 is used to limit the deflection of the filler strip 3.3 during stranding. Each electrical unit core wire 3.1 and optical unit core wire 3.2 passes through a corresponding large core wire hole 1.1 and a small core wire hole 2.1. Each filler strip 3.3 passes through a corresponding large filler strip limiting hole 1.2 and a small filler strip limiting hole 2.2. The distance between the large core wire hole 1.1 and the center of the large splitter plate 1 is greater than the distance between the small core wire hole 2.1 and the center of the small splitter plate 2. The distance between the large filler strip limiting hole 1.2 and the center of the large splitter plate 1 is greater than the distance between the small filler strip limiting hole 2.2 and the center of the small splitter plate 2.

[0024] The large dividing plate 1 and the small dividing plate 2 are coaxially arranged and longitudinally distributed. They are fixedly connected by three connecting rods 4, which are evenly arrayed along the circumference of the small dividing plate 2. The distance between the connecting rod 4 and the center of the small dividing plate 2 is simultaneously less than the distance between the small core wire hole 2.1 and the center of the small dividing plate 2, and the distance between the small filler strip limiting hole 2.2 and the center of the small dividing plate 2. The two ends of the connecting rod 4... Both are equipped with connecting threads. The small dividing plate 2 has a threaded hole for threaded connection to one end of the connecting rod 4, and the large dividing plate 1 has a through hole for connection to the other end of the connecting rod 4. A nut 5 is provided at the end of the through hole near the small dividing plate 2 for threaded connection to the other end of the connecting rod 4. To ensure the connection between the connecting rod 4 and the large dividing plate 1 is secure, if the connecting rod 4 has sufficient length to pass through the large dividing plate 1, a nut 5 is also used for securing the end of the connecting rod 4 away from the small dividing plate 2. Alternatively, the large dividing plate 1 has a threaded hole for threaded connection to one end of the connecting rod 4, and the small dividing plate 2 has a through hole for connection to the other end of the connecting rod 4. A nut 5 is provided at the end of the through hole near the large dividing plate 1 for threaded connection to the other end of the connecting rod 4.

[0025] like Figure 1 , Figure 3As shown, the large dividing plate 1 is provided with a connecting plate 6 for fixed connection with the connecting rod 4. The connection angle between the connecting plate 6 and the large dividing plate 1 is adjustable. The connecting plate 6 is circular. The axis of the large dividing plate 1 is provided with a mounting groove 1.3 for mounting the connecting plate 6. When the connecting plate 6 and the large dividing plate 1 are not fixed, the connecting plate 6 is rotatably connected in the mounting groove 1.3. The mounting groove 1.3 has four fixing holes 1.4 evenly arranged in the circumference. The fixing holes 1.4 are provided with threads. The connecting plate 6 has four arc-shaped grooves 6.1 with the same radius as the fixing holes 1.4 in the circumference. The connecting plate 6 and the large dividing plate 1 are fixedly connected by bolts passing through the arc-shaped grooves 6.1 and the fixing holes 1.4.

[0026] like Figure 1 , Figure 4 , Figure 5 As shown, the size of the large filler strip limiting hole 1.2 is larger than the size of the small filler strip limiting hole 2.2. The large filler strip limiting hole 1.2 is located on the large insert 7, which is detachably connected to the large splitter plate 1. The small filler strip limiting hole 2.2 is located on the small insert 8, which is detachably connected to the small splitter plate 2. Both the large insert 7 and the small insert 8 have flanges 9 at their ends. The large insert 7 is fixedly connected to the large splitter plate 1 by an interference fit, and the small insert 8 is fixedly connected to the small splitter plate 2 by an interference fit. The small core wire hole 2.1 is open on the side away from the center of the small splitter plate 2. Both the large filler strip limiting hole 1.2 and the small filler strip limiting hole 2.2 are processed according to the shape of the filler strip 3.3, which can only allow the filler strip 3.3 to deflect slightly in the large filler strip limiting hole 1.2 and the small filler strip limiting hole 2.2. However, when the filler strip 3.3 is twisted into a bundle, it is already at the limit angle of deflection in the large filler strip limiting hole 1.2 and the small filler strip limiting hole 2.2.

[0027] During the use of the dynamic cable bundling device, a drive roller is installed on the outside of the large splitter plate 1. The drive roller drives the large splitter plate to rotate, thereby realizing the stranding and bundling of the electrical unit core wire 3.1, the optical unit core wire 3.2, and the filler strip 3.3.

[0028] Through the design of the dynamic cable forming and splitting device, during the core wire layer stranding process, the large splitting plate 1 and the small splitting plate 2 are arranged longitudinally, allowing the core wire and the filler strip 3.3 to pass through the large splitting plate 1 and the small splitting plate 2 in sequence, as well as the design of the large core wire hole 1.1, the small core wire hole 2.1, the large filler strip limiting hole 1.2, and the small filler strip limiting hole 2.2. This allows the core wire and the filler strip 3.3 to undergo orderly diameter reduction, avoiding interference between them and ensuring the accuracy of their position during stranding. The design of the large filler strip limiting hole 1.2 and the small filler strip limiting hole 2.2 prevents the filler strip 3.3 from deflecting during the diameter reduction stranding process, thus ensuring the stability of the filler strip 3.3 stranding and the quality of the core wire layer stranding. Furthermore, the adjustable connection length of the connecting rod 4 and the replaceability of the large insert 7 and the small insert 8 enhance the adaptability of the dynamic cable forming and splitting device.

[0029] The above description only illustrates the preferred embodiment of this utility model and should not be construed as limiting the scope of the claims. This utility model is not limited to the above embodiments, and variations in its specific structure are permitted. All changes made within the scope of the independent claims of this utility model are also within the scope of protection of this utility model.
