Description

Technical Field

[0001] The present invention belongs to the technical field of cable processing, in particular to a cable for automated electrical engineering and cable processing equipment. Background Art

[0002] When processing cables, multiple metal wires need to be twisted together according to certain rules to form the conductor of the cable, that is, the cable. There are many twisting methods, such as regular twisting and bundle twisting. In the process of twisting the metal wires, a twisting machine is needed to twist the metal wires;

[0003] The cable stranding machine uses a rotating stranding drum or stranding cage to strand multiple conductors around a central axis at a specific pitch and direction. During the stranding process, the conductors are evenly distributed around the circumference, and the tension control device maintains appropriate tension to ensure that the stranded cable conductor structure is compact and round, with good electrical and mechanical properties.

[0004] However, in the process of twisting the metal wires using a stranding machine, if the tension of the metal wires on different pay-off racks is inconsistent, the individual metal wires on the cable will become loose, which will cause the overall cable structure to be loose and the appearance to be uneven. The wire core is likely to move during use, affecting the electrical and mechanical properties of the cable. Summary of the Invention

[0038] The beneficial effects of the present invention are as follows:

[0039] 1. The present invention describes an automated electrical engineering cable and cable processing equipment. Since the first roller always squeezes and limits the wire core, and since the wire core between the first roller and the stranding mold is in a straightened state, when the traction mechanism is pulling the wire core, the wire core passing through the first roller will also be squeezed and limited. If, in the process of pulling the wire core, the wire core on one or more pay-off racks is pulled out too much, the wire core between the first roller and the pay-off rack will be in a loose state, and the cable between the first roller and the stranding mold will still be in a straightened state. When the loose wire core passes through the first roller, it will be squeezed and limited by the first roller, and then the cable passing through the first roller will also be in a straightened state. In this process, the tension of multiple wire cores can be guaranteed to be relatively consistent when entering the stranding mold, thereby avoiding the situation where the twisted cables are loose.

[0040] 2. The present invention describes an automated electrical engineering cable and cable processing equipment. Since the wire core between the guide wheel and the first roller is in a relaxed state, the wire core on the pay-off frame can be pulled out in advance by utilizing the guide wheel, so that the wire core between the guide wheel and the first roller can be in a relaxed state when twisting the wire. Since all the wire cores between the first roller and the guide wheel are in a relaxed state, all the wire cores can be in the same state when passing through the relative first roller and second roller, thereby further ensuring that the tension of the wire core entering the twisting mold is relatively uniform, and at the same time, it can avoid that some of the wire cores between the guide wheel and the pay-off frame are in a straightened state. When some of the wire cores between the guide wheel and the pay-off frame are in a relaxed state, the required pulling force for the straightened or relaxed wire cores when passing through the first roller and the second roller will be inconsistent, which will cause differences in the tension of the wire cores at different positions.

DETAILED DESCRIPTION

[0055] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0056] It should be noted that the embodiments of the present invention disclose the main or all components of the cable for automated electrical engineering, as well as the structural configuration, functions and operation methods of the cable processing equipment for automated electrical engineering, such as the specific number, specific arrangement and connection relationship of each part in the cable processing equipment for automated electrical engineering, as well as the position, connection relationship, and usage requirements of the parts in the initial state. The purpose is to better demonstrate the present invention so that those skilled in the art can clearly and completely understand the present invention and then implement the present invention, which is as follows:

[0057] like Figures 1 to 12 As shown, on the one hand, the present invention discloses an automated electrical engineering cable processing device, comprising a cable stranding machine; the cable stranding machine comprises a machine base 1;

[0058] A shaft seat 11 is fixedly mounted on the machine base 1; a pay-off wheel 12 is rotatably mounted on the shaft seat 11; a driving wheel 13 is rotatably mounted on the machine base 1 below the pay-off wheel 12, and the driving wheel 13 is used to drive the pay-off wheel 12 to rotate;

[0059] The pay-off wheel 12 is fixed with evenly arranged pay-off frames 14, and the pay-off frames 14 are wound with wire cores 15;

[0060] A plurality of first guide rods 16 are fixedly connected to the pay-off wheel 12, and a stranding mechanism is fixedly installed on the other side of the first guide rods 16;

[0061] like Figure 1 2, a stranding die 17 is installed on the base 1 on the left side of the stranding mechanism, and the stranding die 17 is used to strand multiple wire cores 15 into a cable.

[0062] In this embodiment, the stranding mechanism includes a tapered barrel 2;

[0063] The two ends of the conical cylinder 2 are fixedly connected with a retaining ring 21; the retaining ring 21 close to the first guide rod 16 is fixedly connected to the first guide rod 16; the two retaining rings 21 are centrally connected to the threaded cylinder 22;

[0064] The inner wall of the conical cylinder 2 is provided with evenly arranged wire grooves 23, and the wire grooves 23 are arranged around the conical cylinder 2; the number of the wire grooves 23 is the same as the number of the pay-off frames 14, and they correspond one to one;

[0065] The inner surface of the tapered cylinder 2 is provided with uniformly arranged first chute grooves 24, and the first chute grooves 24 are all connected to the adjacent wire grooves 23;

[0066] The threaded barrel 22 is spirally driven with a ring plate 3; the outer surface of the ring plate 3 is provided with evenly arranged slideways 31; each of the slideways 31 is slidably connected with a straight rod 32;

[0067] Each straight rod 32 is fixedly connected to a roller frame 33 on one side facing the first chute 24, and the roller frame 33 slides in the adjacent first chute 24; each roller frame 33 is rotatably connected to a first roller 34, and the first roller 34 partially extends into the wire groove 23; the outer ring surface of the first roller 34 is fixedly connected to a rubber layer;

[0068] Each of the slideways 31 is provided with a transverse groove 35 on one side of the ring plate 3 near the threaded barrel 22, and the transverse groove 35 is connected to the slideway 31; the retaining ring 21 near the stranding die 17 is fixedly connected with evenly arranged trapezoidal plates 36, and the trapezoidal plates 36 all extend into the transverse groove 35;

[0069] One end surface of each straight rod 32 located in the transverse groove 35 is an inclined surface, and the inclined surface on the straight rod 32 is in contact with the inclined surface on the trapezoidal plate 36 .

[0070] In the present invention, when the stranding mechanism is used in conjunction with the stranding mold 17 and the traction mechanism, the first step is to pull the wire cores 15 on the multiple pay-off wheels 12, and pass the wire cores 15 through the relative wire grooves 23 respectively. When the wire core 15 passes through the wire groove 23, the wire core 15 will pass through the first roller 34. After the wire core 15 passes through the other side of the wire groove 23, the multiple wire cores 15 are passed through the stranding mold 17. After the multiple wire cores 15 pass through the stranding mold 17, the stranding mechanism can then be used to squeeze and limit the multiple wire cores 15.

[0071] In the second step, the stranding mechanism of the present invention is involved. When the core 15 is squeezed and limited, the threaded barrel 22 is first rotated. The threaded barrel 22 rotates in the two retaining rings 21, as shown in FIG. Figure 9-10 As shown in the attached Figure 9-10 From the perspective of , due to the spiral transmission of the ring plate 3 and the threaded cylinder 22, the ring plate 3 is driven to move toward the left. During the movement of the ring plate 3, the straight rod 32 is driven to move to the left. The straight rod 32 moving to the left moves along the inclined surface of the trapezoidal plate 36. At the same time, the straight rod 32 gradually slides out of the slide 31 and gradually drives the roller frame 33 and the first roller 34 to slide into the first slide groove 24. When the first roller 34 gradually moves into the first slide groove 24, it gradually approaches the wire core 15 and gradually squeezes and limits the wire core 15.

[0072] As the first roller 34 gradually squeezes the wire core 15, the wire core 15 in contact with the first roller 34 will gradually sink into the rubber layer. Since the rubber layer squeezes the wire core 15, the wire core 15 can be squeezed and limited, and then the wire core 15 passing through the stranding mold 17 is pulled. When the wire core 15 is pulled, the wire core 15 between the first roller 34 and the stranding mold 17 will gradually be straightened. When all the wire cores 15 are straightened, a traction mechanism (not shown in the figure) can be used to pull all the wire cores 15, and then the stranding work can be carried out.

[0073] In the third step, when twisting the wire, the cable passing through the stranding mold 17 is continuously pulled by the traction mechanism, and the driving wheel 13 drives the pay-off wheel 12 to rotate. The rotating pay-off wheel 12 will drive multiple pay-off frames 14 and the wire core 15 to rotate. At the same time, the pay-off wheel 12 will drive the conical cylinder 2 to rotate through the first guide rod 16. The rotating conical cylinder 2 and the wire core 15 will be twisted with each other in the stranding mold 17 to finally form a cable. When the traction mechanism continues to pull the wire core 15, it will gradually pull the cable out of the pay-off frame 14, and then the cable will pass through the wire groove 23 and the first roller 34, and then be twisted.

[0074] In summary, since the first roller 34 always squeezes and limits the wire core 15, and since the wire core 15 between the first roller 34 and the stranding mold 17 is in a straightened state, when the traction mechanism is pulling the wire core 15, the wire core 15 passing through the first roller 34 will also be squeezed and limited. If in the process of pulling the wire core 15, the wire core 15 on one or more pay-off frames 14 is pulled out too much, the wire core 15 between the first roller 34 and the pay-off frame 14 will be in a relaxed state, and the cable between the first roller 34 and the stranding mold 17 will still be in a straightened state. When the relaxed wire core 15 passes through the first roller 34, it will be squeezed and limited by the first roller 34, and then the cable passing through the first roller 34 will also be in a straightened state. In this process, the tension of multiple wire cores 15 can be guaranteed to be relatively consistent when entering the stranding mold 17, thereby avoiding the looseness of the twisted cables.

[0075] At the same time, since the first roller 34 moves with the ring plate 3, the force of squeezing the wire core 15 can be adjusted by moving the distance of the ring plate 3, so that the wire core 15 can be squeezed with different forces, so that multiple wire cores 15 can enter the stranding mold 17 for stranding in a relatively uniform tensile state, thereby improving the stranding quality of the wire core 15.

[0076] At the same time, the present invention is also suitable for twisting the wire cores 15 in cables with different diameters by moving the ring plate 3. During specific processing and manufacturing, the twisting mechanism of the present invention can be designed and manufactured according to the diameter of the twisted wire core 15 as needed. For example, the twisting mechanism can be designed and manufactured when the diameter of the wire core 15 is in the range of 10-20.6 mm. However, it should be noted that when twisting wire cores 15 of different diameters, the twisting mold 17 needs to be replaced accordingly. Because the diameters of the wire cores 15 are different, the diameters of the twisting holes in the twisting mold 17 are also different. Among them, the twisting mold 17 and the traction mechanism are both existing technologies and are components of the cable twisting machine. The present invention will not be elaborated and explained in detail here.

[0077] In another embodiment of the present invention, a straight groove 37 is formed on the end surface of the trapezoidal plate 36 facing the straight rod 32, and the cross section of the straight groove 37 is C-shaped;

[0078] The inclined surfaces at the bottom of the straight rods 32 are fixedly connected with ball shafts 38 , and the ball shafts 38 slide in the opposite straight grooves 37 .

[0079] In this embodiment, a second chute 25 is provided on the inner wall of the conical cylinder 2 on a side of each of the wire troughs 23 away from the first chute 24 ;

[0080] A second roller 26 is provided in the second chute 25, and a rubber layer is also fixedly connected to the outer surface of the second roller 26; side plates 27 are provided on both sides of the second roller 26, and the second roller 26 rotates on the two side plates 27 via a rotating shaft 28;

[0081] The rotating shaft 28 extends to the opposite side of the two side plates 27; a third sliding groove 29 is opened in the second sliding groove 25 on the opposite side of the two side plates 27, and the rotating shaft 28 rotates in the third sliding groove 29;

[0082] Two push plates 39 are fixedly connected to the roller frame 33 ; a guide groove 271 is formed on the side plates 27 on both sides of each second roller 26 , and the other side of the push plate 39 slides in the guide groove 271 .

[0083] Among them, the purpose of this embodiment is to further improve the present invention, that is, since the ball shaft 38 fixedly connected to the bottom of the straight rod 32 slides in the straight groove 37, when the straight rod 32 moves along the trapezoidal plate 36, the ball shaft 38 on the straight rod 32 will move along the straight groove 37. When the straight rod 32 returns to its initial state, it also moves along the straight groove 37 through the ball shaft 38. During this process, the straight rod 32 can be limited to prevent the straight rod 32 from sliding in the slide 31.

[0084] Since the second roller 26 is rotatably connected in the second slide groove 25, and the wire core 15 passes between the first roller 34 and the second roller 26, and the wire core 15 is squeezed and limited by the rubber layer on the first roller 34 and the second roller 26, in this process, it is avoided that the wire core 15 is squeezed into the wire groove 23 only by the first roller 34. When the wire core 15 is pulled, the wire core 15 will rub against the wire groove 23, thereby causing the wire core 15 to wear, thereby improving the twisting quality of the wire core 15.

[0085] Furthermore, since the push plate 39 fixedly connected to the roller frame 33 slides in the guide groove 271 of the side plates 27 on both sides of the second roller 26, when the first roller 34 and the roller frame 33 move following the straight rod 32, the push plate 39 on the roller frame 33 will push the two side plates 27 and the second roller 26 to move, and the rotating shaft 28 on the second roller 26 will move along the third slide groove 29. In this process, the first roller 34 and the second roller 26 can always correspond to each other, thereby avoiding the situation where the second roller 26 is misaligned after the first roller 34 moves.

[0086] In another embodiment of the present invention, a compensation mechanism is provided on the side of the stranding mechanism facing the pay-off wheel 12;

[0087] The compensation mechanism includes a plurality of straight plates 4; the plurality of straight plates 4 are fixedly connected to adjacent ring plates 3;

[0088] The ends of the straight plate 4 are rotatably connected to two opposing guide wheels 41; a rectangular rod 42 is fixedly connected to a rotating rod on one of the guide wheels 41, and the rectangular rod 42 is located on the opposite side of the straight plate 4;

[0089] The guide wheel 41 fixedly connected to the rectangular rod 42 is fixedly connected with gear teeth 43 , and the other guide wheel 41 is provided with a first tooth groove 44 meshing with the gear teeth 43 ; the rectangular rod 42 is slidably connected with a first rotating wheel 48 .

[0090] like Figure 3 As shown, a transverse cylinder 46 is provided on one side of the plurality of straight plates 4 close to the guide wheel 41; a second guide rod 45 is fixedly connected to the end surface of the transverse cylinder 46 facing the shaft seat 11, and the other side of the second guide rod 45 is fixedly connected to the shaft seat 11;

[0091] An annular stepped groove 47 is formed on the end surface of the horizontal cylinder 46 close to the straight plate 4 . It should be noted that, in the initial state, the first runner 48 is located in the stepped groove 47 and is tangent to the stepped groove 47 .

[0092] In this embodiment, when the wire core 15 is pulled, the wire core 15 passes through two opposite guide wheels 41 on each straight plate 4, and the wire core 15 between the first roller 34 and the guide wheel 41 is in a relaxed state;

[0093] Since the horizontal cylinder 46 is fixedly connected to the shaft seat 11 through the second guide rod 45, and the horizontal cylinder 46 is in a stationary state, when the conical cylinder 2 drives the straight plate 4 to revolve, the straight plate 4 will drive the relative guide wheel 41 to rotate, wherein the rectangular rod 42 fixedly connected to the guide wheel 41 also rotates with the guide wheel 41, and the rectangular rod 42 will drive the first rotating wheel 48 to rotate along the annular stepped groove 47. During the rotation of the first rotating wheel 48 along the annular stepped groove 47, the first rotating wheel 48 itself will rotate, and the rotating first rotating wheel 48 will rotate. The rectangular rod 42 is driven to rotate, and the rectangular rod 42 will drive one of the guide wheels 41 on the straight plate 4 to rotate. Since the two guide wheels 41 are respectively provided with mutually meshing gear teeth 43 and first tooth grooves 44, the rotating guide wheel 41 will drive the other guide wheel 41 to rotate. During the rotation of the two relative guide wheels 41, the wire core 15 will be pulled, so that the wire core 15 can be pulled off the wire pay-off frame 14, and the speed at which the two guide wheels 41 pull the wire core 15 is the same as the speed at which the traction mechanism pulls the wire core 15 through the stranding mold 17.

[0094] Furthermore, since the wire core 15 between the guide wheel 41 and the first roller 34 is in a relaxed state, the wire core 15 on the pay-off frame 14 can be pulled out in advance by using the guide wheel 41, so that the wire core 15 between the guide wheel 41 and the first roller 34 can be in a relaxed state when twisting the wire. Since all the wire cores 15 located between the first roller 34 and the guide wheel 41 are in a relaxed state, the state of all the wire cores 15 can be the same when passing through the relative first roller 34 and second roller 26, thereby further ensuring that the tension of the wire core 15 entering the twisting mold 17 is relatively uniform, and at the same time, it can avoid that part of the wire core 15 between the guide wheel 41 and the pay-off frame 14 is in a straightened state. When part of the wire core 15 between the guide wheel 41 and the pay-off frame 14 is in a relaxed state, the required pulling force for the straightened or relaxed wire core 15 when passing through the first roller 34 and the second roller 26 will be inconsistent, which will cause differences in the tension of the wire core 15 at different positions.

[0095] In another embodiment of the present invention, the guide wheel 41 and the conical cylinder 2 are located on the straight plate 4, and are slidably connected with a vertical rod 5; a plurality of vertical rods 5 are provided with a through slot 51 on opposite sides; a spring is connected between the vertical rod 5 and the straight plate 4;

[0096] A second rotating wheel 52 is slidably connected on the rectangular rod 42 between the first rotating wheel 48 and the straight plate 4 , and the second rotating wheel 52 is connected to the first rotating wheel 48 via a connecting rod 53 ; the diameter of the second rotating wheel 52 is smaller than that of the first rotating wheel 48 .

[0097] The distance between the first rotating wheel 48 and the second rotating wheel 52 is equal to the sum of the thicknesses of the first rotating wheel 48 and the second rotating wheel 52; after the second rotating wheel 52 moves, it will be tangent to the left end surface of the horizontal cylinder 46; the plurality of vertical rods 5 are fixedly connected to the opposite side with a connecting plate 54;

[0098] The connecting plate 54 extends to one side of the rectangular rod 42; a push ring 55 is fixedly connected to the connecting plate 54, and the push ring 55 is located between the first rotating wheel 48 and the second rotating wheel 52, and the connecting rod 53 is located inside the push ring 55;

[0099] The first rotating wheel 48 and the second rotating wheel 52 have opposite sides with rounded corners.

[0100] When pulling the wire core 15, the wire core 15 is passed through the through groove 51. Since the cable between the first roller 34 and the guide wheel 41 is in a relaxed state, it is in the initial state when passing through the vertical pole 5. As the wire core 15 continues to be twisted, if the wire core 15 between the first roller 34 and the guide wheel 41 is gradually in a straightened state, the straightened wire core 15 will push the vertical pole 5 to gradually move toward the threaded barrel 22, and at the same time will gradually compress the spring.

[0101] As the upright 5 moves, the connecting plate 54 is driven to move, and the moving connecting plate 54 drives the push ring 55 to move. When the push ring 55 moves, the first runner 48 is pushed to gradually move toward the middle of the horizontal cylinder 46. Since the first runner 48 and the second runner 52 are connected by the connecting rod 53, the second runner 52 is driven to gradually approach the side of the horizontal cylinder 46. As the first runner 48 gradually moves, it gradually separates from the stepped groove 47, and the second runner 52 gradually approaches the horizontal cylinder 46 side, when the first wheel 48 is completely separated from the stepped groove 47, the second wheel 52 contacts the side of the horizontal cylinder 46, and then the second wheel 52 rotates along the side of the horizontal cylinder 46, and the second wheel 52 itself rotates. Since the diameter of the second wheel 52 is smaller than the diameter of the first wheel 48, the number of circles of the second wheel 52 rotating around the side of the horizontal cylinder 46 is more than the number of circles of the first wheel 48 rotating around the stepped groove 47, thereby accelerating the rotation speed of the rectangular rod 42.

[0102] When the rotation speed of the rectangular rod 42 increases, the rotation speed of the two relative guide wheels 41 also increases. When the rotation speed of the guide wheel 41 increases, the wire core 15 on the wire pay-off frame 14 will be pulled between the first roller 34 and the guide wheel 41. At this time, the speed of the relative guide wheel 41 pulling the cable is greater than the speed of the traction mechanism pulling the wire core 15 in the stranding mold 17. Therefore, the wire core 15 located between the first roller 34 and the guide wheel 41 gradually increases and then gradually returns to a relaxed state. When the wire core 15 located between the first roller 34 and the guide wheel 41 gradually returns to a relaxed state, the vertical rod 5 gradually returns to its original state under the action of the spring. At the same time, the push ring 55 will push the second rotating ring and the first rotating ring to move along the rectangular rod 42, so that the second rotating wheel 52 gradually separates from the side of the horizontal cylinder 46, and makes the first rotating wheel 48 gradually tangent to the stepped groove 47. When the first rotating wheel 48 returns to its initial state, it will continue to rotate along the stepped groove 47, while driving the guide wheel 41 to rotate at its original speed.

[0103] It should be pointed out that in the actual processing of the present invention, the first rotating wheel 48 and the second rotating wheel 52 can also be gears with different modules. If the first rotating wheel 48 and the second rotating wheel 52 are gears, tooth grooves can be opened on the side of the horizontal cylinder 46 and in the stepped groove 47.

[0104] Furthermore, when the wire core 15 between the first roller 34 and the guide wheel 41 is gradually in a straightened state, the first rotating wheel 48 is controlled to disengage from the stepped groove 47, and the second rotating wheel 52 is made to contact the side of the cross cylinder 46, thereby accelerating the rotation speed of the guide wheel 41. When the rotation speed of the guide wheel 41 is accelerated, the wire wheel on the wire pay-off frame 14 will be accelerated to be pulled between the first roller 34 and the guide wheel 41. At this time, the speed at which the relative guide wheel 41 pulls the cable is greater than the speed at which the traction mechanism pulls the wire core 15 in the stranded wire mold 17. Therefore, the wire core 15 located between the first roller 34 and the guide wheel 41 gradually increases, and then gradually returns to a relaxed state.

[0105] Furthermore, since the opposite sides of the first rotating wheel 48 and the second rotating wheel 52 are both rounded, the first rotating wheel 48 can be better tangent to the stepped groove 47, and the second rotating wheel 52 can be better tangent to the side of the horizontal cylinder 46.

[0106] On the other hand, the present invention also provides a cable for automated electrical engineering, comprising a cable, an insulation layer, a shielding layer, a filling layer and an outer sheath, etc., wherein the cable is obtained by processing using the above-mentioned cable processing equipment.
