Description

Technical Field

[0001] The present invention belongs to the technical field of cable processing, and specifically relates to a cable and a cable processing device for automated electrical engineering. Background Art When processing cables, multiple metal wires need to be stranded together according to certain rules to form the conductor of the cable, that is, the wire and cable. There are various stranding methods, such as regular stranding, bunch stranding, etc. During the stranding of metal wires, a stranding machine is required to strand the metal wires; The cable stranding machine makes multiple wires strand around a central axis at a certain pitch and direction through a rotating stranding disc or stranding cage. During the stranding process, the wires are evenly distributed on the circumference and maintained at an appropriate tension through a tension control device to ensure that the structure of the stranded cable conductor is tight and round, with good electrical and mechanical properties; However, during the process of stranding metal wires using a stranding machine, if the tensions of the metal wires on different pay-off stands are inconsistent, the single metal wires on the cable will become loose, which will further lead to a loose overall cable structure and an irregular appearance. During use, the wire core is prone to move, affecting the electrical and mechanical properties of the cable. Summary of the Invention

[0007] Specifically, a second chute is opened in the inner wall of the conical cylinder on the side of the wire groove away from the first chute; A second roller is arranged in the second chute, and a rubber layer is fixedly connected to the outer circumferential surface of the second roller; side plates are arranged on both sides of the second roller, and the second roller rotates on the side plates through a rotating shaft; The rotating shaft extends to the opposite side of the side plate; a third chute is opened in the second chute on the opposite side of the side plate, and the rotating shaft rotates in the third chute; A push plate is fixedly connected to the roller frame; guide grooves are opened on the side plates on both sides of the second roller, and the other side of the push plate slides in the guide grooves.

[0008] Specifically, a compensation mechanism is arranged on the side of the stranding mechanism facing the pay-off reel; The compensation mechanism includes a straight plate; the straight plate is fixedly connected to the adjacent ring plates; Two opposite guide wheels are rotatably connected to the end of the straight plate; a rectangular rod is fixedly connected to the rotating rod on one of the guide wheels, and the rectangular rod is located on the opposite side of the straight plate; A gear is fixedly connected to the guide wheel to which the rectangular rod is fixedly connected, and a first tooth groove meshing with the gear is opened on the other guide wheel; a first runner is slidably connected to the rectangular rod; A cross cylinder is arranged on the side of the straight plate close to the guide wheel; a second guide rod is fixedly connected to the end face of the cross cylinder facing the shaft seat, and the other side of the second guide rod is fixedly connected to the shaft seat; An annular stepped groove is opened on the end face of the cross cylinder close to the straight plate.

[0012] On the other hand, the present invention provides a cable for automated electrical engineering, which is characterized in that it includes a cable core, an insulating layer, a shielding layer, a filling layer, and an outer protective layer. Among them, the cable core is processed by the above-mentioned cable processing equipment for automated electrical engineering.

[0013] The beneficial effects of the present invention are as follows: 1. For the cable for automated electrical engineering and the cable processing equipment of the present invention, since the first roller always squeezes and limits the cable core, and since the cable core between the first roller and the stranding die is in a straightened state, when the traction mechanism tractions the cable core, the cable core passing through the first roller will also be squeezed and limited. If during the process of traction of the cable core, the cable cores on one or more pay-off stands are pulled out too much, the cable cores between the first roller and the pay-off stand will be in a slack state, while the cable between the first roller and the stranding die remains in a straightened state. When the slack cable 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 is also in a straightened state. During this process, it can ensure that the tensions of multiple cable cores are relatively consistent when entering the stranding die, thereby avoiding the situation that the stranded cable is loose.

[0014] 2. For the cable and cable processing equipment for automated electrical engineering described in the present invention, since the wire core between the guide wheel and the first roller is in a relaxed state, by using the guide wheel to pull out the wire core on the wire reel in advance, the wire core between the guide wheel and the first roller can be in a relaxed state during stranding. Since all the wire cores located between the first roller and the guide wheel are in a relaxed state, the states of all the wire cores when passing through the opposing first roller and second roller can be the same, thereby further ensuring that the tension of the wire cores entering the stranding die is relatively uniform. At the same time, it can avoid the situation where some of the wire cores between the guide wheel and the wire reel are in a straightened state and some are in a relaxed state, which would cause inconsistent pulling forces required for the straightened or relaxed wire cores when passing through the first roller and the second roller, resulting in differences in the tension of wire cores at different positions.

[0018] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0019] It should be noted that in the embodiments of the present invention, the main or all components of the cable for automated electrical engineering, as well as the structural configuration, functions and operation modes of the cable processing equipment for automated electrical engineering are disclosed. For example, the specific numbers of various parts in the cable processing equipment for automated electrical engineering, the specific arrangement manners and connection relationships, as well as the positions, connection relationships and usage requirements of the parts in the initial state are disclosed. The purpose is to better display the present invention, so that those skilled in the art can clearly and completely understand the present invention and then implement the present invention. Specifically as follows: As Figures 1 to 12 shown, on the one hand, the present invention discloses a cable processing equipment for automated electrical engineering, including a cable strander; the cable strander includes a machine base 1; An axle seat 11 is fixedly installed on the machine base 1; a pay-off reel 12 is rotatably installed on the axle seat 11; a driving wheel 13 is rotatably installed on the machine base 1 below the pay-off reel 12, and the driving wheel 13 is used to drive the pay-off reel 12 to rotate; Evenly arranged pay-off frames 14 are fixedly installed on the pay-off reel 12, and a core wire 15 is wound on the pay-off frames 14; A plurality of first guide rods 16 are fixedly connected to the pay-off reel 12, and a stranding mechanism is fixedly installed together on the other side of the first guide rods 16; As Figure 1 shown in the perspective view of the attached drawing as shown in or 2, on the left side of the stranding mechanism, a stranding die 17 is installed on the machine base 1, and the stranding die 17 is used to strand multiple core wires 15 into a cable.

[0020] In this embodiment, the stranding mechanism includes a conical cylinder 2; Both ends of the conical cylinder 2 are fixedly connected with retaining rings 21; the retaining ring 21 close to the first guide rod 16 is fixedly connected with the first guide rod 16; a threaded cylinder 22 is rotatably connected to the centers of the two retaining rings 21; A wire guiding groove 23 is formed in the inner wall of the conical cylinder 2 and is arranged uniformly, and the wire guiding groove 23 surrounds the conical cylinder 2; the number of the wire guiding grooves 23 is the same as that of the wire pay-off frames 14 and corresponds one by one; A first sliding groove 24 is formed in the inner circumferential surface of the conical cylinder 2 and is arranged uniformly, and the first sliding groove 24 is communicated with the adjacent wire guiding groove 23; A ring plate 3 is in screw drive with the threaded cylinder 22; a slideway 31 is formed in the outer circumferential surface of the ring plate 3 and is arranged uniformly; a straight rod 32 is slidably connected in each slideway 31; One side of each straight rod 32 facing the first sliding groove 24 is fixedly connected with a roller frame 33, and the roller frame 33 slides in the adjacent first sliding groove 24; a first roller 34 is rotatably connected to each roller frame 33, and a part of the first roller 34 extends into the wire guiding groove 23; a rubber layer is fixedly connected to the outer circumferential surface of the first roller 34; A transverse groove 35 is formed in the ring plate 3 on one side of each slideway 31 close to the threaded cylinder 22, and the transverse groove 35 is communicated with the slideway 31; uniformly arranged trapezoidal plates 36 are fixedly connected to the retaining ring 21 close to the stranding die 17, and the trapezoidal plates 36 all extend into the transverse groove 35; One end face 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 fit with the inclined surface on the trapezoidal plate 36.

[0021] In the stranding mechanism of the present invention, when cooperating with the stranding die 17 and the traction mechanism, the first step: the wire cores 15 on a plurality of wire pay-off wheels 12 are tractioned, and the wire cores 15 are respectively passed through the opposite wire guiding grooves 23. When the wire cores 15 pass through the wire guiding grooves 23, the wire cores 15 will pass through the first rollers 34. After the wire cores 15 pass through the other side of the wire guiding grooves 23, the plurality of wire cores 15 are passed through the stranding die 17. After the plurality of wire cores 15 pass through the stranding die 17, then the stranding mechanism can be used to extrude and limit the plurality of wire cores 15.

[0022] The second step, the stranding mechanism in the present invention participates. When extruding and limiting the wire cores 15, first rotate the threaded cylinder 22, and the threaded cylinder 22 will rotate in the two retaining rings 21, as Figures 9 - 10 shown, in the attached Figures 9 - 10In the perspective of [description], since the ring plate 3 and the threaded barrel 22 are in screw drive, the ring plate 3 will be driven to move towards the left. During the movement of the ring plate 3, the straight rod 32 will be driven to move leftward. The leftward moving straight rod 32 will move along the inclined surface of the trapezoidal plate 36. At the same time, the straight rod 32 will gradually slide out of the slideway 31 and gradually drive the roller frame 33 and the first roller 34 to slide into the first chute 24. When the first roller 34 gradually moves into the first chute 24, it will gradually approach the wire core 15 and gradually squeeze and limit the wire core 15. When 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. Subsequently, pull the wire core 15 passing through the stranding die 17. When the wire core 15 is pulled, the wire core 15 between the first roller 34 and the stranding die 17 will be gradually straightened. When all the wire cores 15 are straightened, the traction mechanism (not shown in the figure) can be used to traction all the wire cores 15, and then the stranding work can be carried out.

[0023] In the third step, when stranding, the traction mechanism continuously traction the cable passing through the stranding die 17. At the same time, the driving wheel 13 drives the wire reel 12 to rotate. The rotating wire reel 12 will drive a plurality of wire reels 14 and the wire cores 15 to rotate. At the same time, the wire reel 12 will drive the conical cylinder 2 to rotate through the first guide rod 16. The rotating conical cylinder 2 and the wire cores 15 will be twisted with each other in the stranding die 17 to finally form a cable. When the traction mechanism continuously traction the wire core 15, the cable will be gradually pulled away from the wire reel 14. Subsequently, the cable will pass through the wire guide groove 23 and the first roller 34 and then be stranded.

[0024] Generally speaking, 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 die 17 is in a straightened state, when the traction mechanism traction the wire core 15, the wire core 15 passing through the first roller 34 will also be squeezed and limited. If during the traction of the wire core 15, the wire core 15 on one or more wire reels 14 is pulled out too much, the wire core 15 between the first roller 34 and the wire reel 14 will be in a slack state, and the cable between the first roller 34 and the stranding die 17 is still in a straightened state. When the slack 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 is also in a straightened state. During this process, it can ensure that the tensions of multiple wire cores 15 are relatively consistent when entering the stranding die 17, thus avoiding the situation that the stranded cable is loose.

[0025] Meanwhile, since the first roller 34 moves along with the ring plate 3, the force squeezing the wire core 15 can be adjusted by the distance of moving the ring plate 3, so as to squeeze the wire core 15 with different forces, enabling multiple wire cores 15 to enter the stranding die 17 in a relatively uniform stretching state for stranding, and improving the stranding quality of the wire core 15.

[0026] Meanwhile, by moving the ring plate 3, the present invention is also applicable to stranding the wire cores 15 in cables with different diameters. During specific processing and manufacturing, the stranding mechanism in the present invention can be designed and manufactured according to the diameter of the wire core 15 to be stranded. For example, when the diameter of the wire core 15 ranges from 10 to 20.6 mm, the stranding mechanism can be designed and manufactured. However, it should be noted that when stranding wire cores 15 with different diameters, the stranding die 17 needs to be replaced correspondingly, because the diameters of the stranding holes in the stranding die 17 are different for wire cores 15 with different diameters. Among them, the stranding die 17 and the traction mechanism are both prior arts and are components of the cable stranding machine, and the present invention will not elaborate and explain them too much here.

[0027] In another embodiment of the present invention, straight grooves 37 are respectively formed on the side end faces of the trapezoidal plate 36 facing the straight rod 32, and the cross-section of the straight groove 37 is C-shaped. Ball shafts 38 are respectively fixedly connected to the inclined surfaces at the bottoms of the straight rods 32, and the ball shafts 38 are respectively slidably arranged in the corresponding straight grooves 37.

[0028] In this embodiment, a second chute 25 is formed in the inner wall of the conical cylinder 2 on the side of each wire groove 23 away from the first chute 24. A second roller 26 is arranged in the second chute 25, and a rubber layer is also fixedly connected to the outer circumferential surface of the second roller 26. Side plates 27 are arranged on both sides of the second roller 26, and the second roller 26 is rotatably arranged on the two side plates 27 through a rotating shaft 28. The rotating shaft 28 extends to the opposite sides of the two side plates 27. Third chutes 29 are formed in the second chute 25 on the opposite sides of the two side plates 27, and the rotating shaft 28 is rotatably arranged in the third chutes 29. Two push plates 39 are fixedly connected to the roller frame 33. Guide grooves 271 are respectively formed on the side plates 27 on both sides of each second roller 26, and the other sides of the push plates 39 are respectively slidably arranged in the guide grooves 271.

[0029] 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, the ball shaft 38 also moves along the straight groove 37. During this process, the straight rod 32 can be limited, thereby preventing the straight rod 32 from sliding in the slideway 31.

[0030] Since a second roller 26 is rotatably connected in the second chute 25, and the core 15 passes between the first roller 34 and the second roller 26, and the rubber layers on the first roller 34 and the second roller 26 are used to extrude and limit the core 15. In this process, it is avoided that the core 15 is only extruded into the wire chute 23 by the first roller 34. When the core 15 is pulled, the core 15 will rub against the wire chute 23, resulting in wear of the core 15, and the stranding quality of the core 15 is improved.

[0031] Furthermore, since the push plate 39 fixedly connected to the roller frame 33 slides in the guide grooves 271 on the side plates 27 on both sides of the second roller 26, when the first roller 34 and the roller frame 33 move along with 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 chute 29. In this process, the first roller 34 and the second roller 26 can always correspond to each other, so that it can be avoided that the second roller 26 is misaligned after the first roller 34 moves.

[0032] In another embodiment of the present invention, a compensation mechanism is provided on one side of the stranding mechanism facing the pay-off reel 12; The compensation mechanism includes a plurality of straight plates 4; a plurality of the straight plates 4 are fixedly connected to the adjacent ring plates 3; Two opposite guide wheels 41 are rotatably connected to the end of the straight plate 4; a rectangular rod 42 is fixedly connected to the 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; A gear tooth 43 is fixedly connected to the guide wheel 41 to which the rectangular rod 42 is fixedly connected, and a first tooth groove 44 meshing with the gear tooth 43 is formed on the other guide wheel 41; a first runner 48 is slidably connected to the rectangular rod 42.

[0033] As Figure 3 shown, a transverse cylinder 46 is provided on one side of the plurality of straight plates 4 close to the guide wheels 41; a second guide rod 45 is fixedly connected to the end face 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; An annular stepped groove 47 is formed on the end face of the transverse 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.

[0034] In this embodiment, when the core 15 is pulled, the core 15 is passed through the two opposite guide wheels 41 on each straight plate 4, and the core 15 between the first roller 34 and the guide wheel 41 is in a relaxed state; 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. Among them, the rectangular rod 42 fixedly connected to the guide wheel 41 also rotates following the guide wheel 41, and the rectangular rod 42 will drive the first runner 48 to rotate along the annular stepped groove 47. During the process of the first runner 48 rotating along the annular stepped groove 47, the first runner 48 itself will rotate. The rotating first runner 48 will drive the rectangular rod 42 to rotate, and the rectangular rod 42 will drive one of the guide wheels 41 on the straight plate 4 to rotate. Since the meshing gear teeth 43 and the first tooth grooves 44 are respectively arranged on the two guide wheels 41, 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 tractioned, so that the wire core 15 can be pulled off from the wire pay-off frame 14, and the speed of the two guide wheels 41 tractioning the wire core 15 is the same as the speed of the traction mechanism tractioning the wire core 15 passing through the stranding die 17.

[0035] Further, since the wire core 15 between the guide wheel 41 and the first roller 34 is in a slack state, by using the guide wheel 41 to pull out the wire core 15 on the wire pay-off frame 14 in advance, the wire core 15 between the guide wheel 41 and the first roller 34 can be in a slack state during stranding. Since all the wire cores 15 located between the first roller 34 and the guide wheel 41 are in a slack state, the states of all the wire cores 15 when passing through the relative first roller 34 and the second roller 26 can be the same, so as to further ensure that the tensions of the wire cores 15 entering the stranding die 17 are relatively unified. At the same time, it can be avoided that when some of the wire cores 15 between the guide wheel 41 and the wire pay-off frame 14 are in a straightened state and some of the wire cores 15 between the guide wheel 41 and the wire pay-off frame 14 are in a slack state, the required pulling forces of the straightened or slack wire cores 15 when passing through the first roller 34 and the second roller 26 are inconsistent, resulting in differences in the tensions of the wire cores 15 at different positions.

[0036] In another embodiment of the present invention, vertical rods 5 are slidably connected to the straight plate 4 between the guide wheel 41 and the conical cylinder 2; through grooves 51 are formed on the opposite sides of the plurality of vertical rods 5; springs are connected between the vertical rods 5 and the straight plate 4; A second runner 52 is slidably connected to the rectangular rod 42 between the first runner 48 and the straight plate 4, and the second runner 52 is connected to the first runner 48 through a connecting rod 53; the diameter of the second runner 52 is smaller than the diameter of the first runner 48.

[0037] The distance between the first runner 48 and the second runner 52 is equal to the sum of the thicknesses of the first runner 48 and the second runner 52; after the second runner 52 moves, it will be tangent to the left end face of the horizontal cylinder 46; connecting plates 54 are fixedly connected to the opposite sides of the plurality of vertical rods 5; The connecting plate 54 extends to one side of the rectangular rod 42; a pushing ring 55 is fixedly connected to the connecting plate 54, and the pushing ring 55 is located between the first runner 48 and the second runner 52, and the connecting rod 53 is located inside the pushing ring 55; Both opposite sides of the first runner 48 and the second runner 52 are designed with rounded corners.

[0038] When the traction core 15 is pulled, the 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 slack state, the vertical rod 5 is in an initial state. As the core 15 continues to be stranded, when the core 15 between the first roller 34 and the guide wheel 41 gradually becomes straightened, the straightened core 15 will push the vertical rod 5 to gradually move towards the threaded cylinder 22, and at the same time, the spring will be gradually compressed.

[0039] During the movement of the vertical rod 5, it will drive the connecting plate 54 to move, and the moving connecting plate 54 will drive the pushing ring 55 to move. When the pushing ring 55 moves, it will push the first runner 48 to gradually move towards the middle position of the horizontal cylinder 46. Since the first runner 48 and the second runner 52 are connected by the connecting rod 53, it will drive the second runner 52 to gradually approach the side of the horizontal cylinder 46. During the gradual movement of the first runner 48, it will gradually separate from the stepped groove 47. At the same time, the second runner 52 will gradually approach the side of the horizontal cylinder 46. When the first runner 48 is completely separated from the stepped groove 47, at this time, the second runner 52 contacts the side of the horizontal cylinder 46, and then the second runner 52 will rotate along the side of the horizontal cylinder 46, and the second runner 52 itself will rotate. Since the diameter of the second runner 52 is smaller than the diameter of the first runner 48, the number of turns of the second runner 52 rotating around the side of the horizontal cylinder 46 is more than the number of turns of the first runner 48 rotating around the stepped groove 47. Therefore, the rotation speed of the rectangular rod 42 will be accelerated.

[0040] When the rotation speed of the rectangular rod 42 is accelerated, the rotation speeds of the two opposite guide wheels 41 are also accelerated. When the rotation speed of the guide wheel 41 is accelerated, it will accelerate the traction of the core 15 on the wire reel 14 to between the first roller 34 and the guide wheel 41. At this time, the speed of the opposite guide wheel 41 pulling the cable is greater than the speed of the traction mechanism pulling the core 15 in the stranding die 17. Therefore, the core 15 between the first roller 34 and the guide wheel 41 gradually increases, and then gradually returns to the slack state. When the core 15 between the first roller 34 and the guide wheel 41 gradually returns to the slack state, at this time, the vertical rod 5 gradually returns to its original state under the action of the spring, and at the same time, the second rotating ring and the first rotating ring will be pushed along the rectangular rod 42 through the pushing ring 55, so that the second runner 52 gradually disengages from the side of the horizontal cylinder 46, and the first runner 48 gradually becomes tangent to the stepped groove 47. When the first runner 48 returns to the initial state, it will continue to rotate along the stepped groove 47, and at the same time, drive the guide wheel 41 to rotate at the original speed.

[0041] It should be noted that during the actual processing of the present invention, the first runner 48 and the second runner 52 can also be gears of different modules. If the first runner 48 and the second runner 52 are gears, tooth grooves can be opened on the side surface of the horizontal cylinder 46 and in the stepped groove 47.

[0042] Furthermore, when the wire core 15 between the first roller 34 and the guide wheel 41 is gradually in a straightened state, by controlling the first runner 48 to disengage from the stepped groove 47 and making the second runner 52 contact the side surface of the horizontal cylinder 46, the rotation speed of the guide wheel 41 will be accelerated. After the rotation speed of the guide wheel 41 is accelerated, the wire wheel on the wire pay-off rack 14 will be accelerated to be pulled between the first roller 34 and the guide wheel 41. At this time, the speed of the guide wheel 41 pulling the cable is greater than the speed of the traction mechanism pulling the wire core 15 in the stranding die 17. Therefore, the wire core 15 between the first roller 34 and the guide wheel 41 gradually increases and then gradually returns to a relaxed state.

[0043] Furthermore, since both the opposite sides of the first runner 48 and the second runner 52 are designed with rounded corners, the first runner 48 can be better tangent to the stepped groove 47, and the second runner 52 can be better tangent to the side surface of the horizontal cylinder 46.

[0044] On the other hand, the present invention also provides a cable for automated electrical engineering, including a cable, an insulating layer, a shielding layer, a filling layer, an outer protective layer, etc. Among them, the cable is obtained by processing through the above-mentioned cable processing equipment.
