Description

Technical Field

[0001] This invention relates to the field of cable production technology, and more specifically, to a rotary die device for a cable production frame stranding machine. Background Technology

[0002] When using a frame-type stranding machine, multiple reels are installed around the circumference of the stranding cage. The reels should be positioned symmetrically relative to the central axis of the cage to ensure a more uniform distribution, consistent wire supply, and improved stranding quality. The reels on the periphery of the frame-type stranding machine are often fixed using clamping mechanisms, which can introduce errors. Therefore, manual inspection is often required after installation. Continuous grooves on the wire core surface are generally caused during wire pulling, resulting in poor lubrication and aluminum adhesion. Discontinuous grooves may be caused by foreign matter adhering to the stranding die. Chinese Patent Publication No. CN115762910B discloses "A Rotating Die Device for a Frame Stranding Machine". In this patent, the cable lengths delivered to different positions of the stranding assembly within the same time period are different by the cable puller, thereby reducing the cable deformation, reaction force, clamping force and damage to the cable. The cable is wound on a first winding rod or a second winding rod. During the rotation of the first winding rod and the second winding rod, the cable is released to the stranding assembly. At this time, there is rolling friction between the cable and the first winding rod or the second winding rod, and the friction force is small, resulting in less wear and damage to the cable. The second winding rod is fitted inside the first winding rod, reducing the volume of the cable puller.

[0003] Existing rotating die equipment for cable production frame stranding machines has structural design flaws, which require manual intervention to adjust the rotation angle when the upper and lower spools are in use. This makes it impossible to achieve automated management of the upper spool and wire spool conveying of the frame stranding machine. Furthermore, when the wire core is guided to the stranding die, it is easy for the wire to jump, resulting in excessive single-wire stranding resistance. Summary of the Invention

[0004] This invention proposes a rotary die device for a cable production frame stranding machine, which solves the problems in related technologies where manual intervention is required to adjust the rotation angle when the upper and lower spools are moved, making it impossible to achieve automated management of the upper spool and wire spool conveying of the frame stranding machine, and where wire cores are easily skipped when guided to the stranding die, resulting in excessive single-wire stranding resistance.

[0005] The technical solution of the present invention is as follows:

[0006] A rotary die device for a cable stranding machine includes a linear guide rail, a lead screw slide fixedly connected to the output end of the linear guide rail, a telescopic motor fixedly connected to the output end of the lead screw slide, a limit plate fixedly connected to the output end of the telescopic motor, and two fixed platforms fixedly connected to the side of the linear guide rail. The device also includes:

[0007] A wire spool fixing mechanism is rotatably mounted on the inner side of a fixing platform. The wire spool fixing mechanism is used for limiting and guiding the wire spool and for lubricating the surface of the wire.

[0008] A locking mechanism is fixedly installed on the inner side of the wire reel fixing mechanism. The locking mechanism is used for locking and limiting the wire winding and unwinding. The fixing platform provides rotational support for the connecting reel and the lubrication assembly. The surface of the unwinding assembly is wound with wire. When the fixing tube is driven to rotate, multiple wires are twisted into conductor strands. In the prior art, multiple winding reels are arranged side by side and the upper reel is tilted to make the multiple winding reels aligned. When the motor drives the fixing tube to rotate, it is not easy to adjust the angle, so the operator needs to adjust it repeatedly.

[0009] An anti-skid wire mechanism is fixedly installed at the middle position on the surface of the wire reel fixing mechanism. The anti-skid wire mechanism is used to guide the traction and reversal of the metal wire after the wire is released.

[0010] The spool fixing mechanism includes a connecting plate, which is rotatably mounted on the inner side of the fixing platform. A fixing tube is fixedly connected to the surface of the connecting plate. An extension tube and a barrier plate are fixedly connected to the surface of the fixing tube. A wire feeding assembly is fixedly connected to the inner side of the fixing tube. A lubrication assembly is fixedly connected to the end of the fixing tube away from the connecting plate. The surface of the limiting plate engages with the side of the winding wheel near the locking hole. A linear guide rail drives the lead screw slide to move to a position directly below the drive motor. The telescopic motor drives the limiting plate and the winding wheel to rotate and move upward. The threaded tube is screwed into the inner side of the internal threaded sleeve. The winding wheel is tightly engaged with the internal threaded sleeve through the thread. The end face of the metal wire passes through the openings on the surfaces of the first plate and the second plate. A drive motor is fixedly connected to the surface of the fixing platform.

[0011] Preferably, the wire feeding assembly includes a drive motor, which is fixedly mounted on the inner side of the fixed tube, and the output end of the drive motor is fixedly connected to an internal threaded sleeve.

[0012] Preferably, the wire feeding assembly further includes a threaded tube, the surface of which is connected to the inner side of the internal threaded sleeve via threads, and a winding wheel is fixedly connected to the end face of the threaded tube, with a locking hole on the surface of the winding wheel.

[0013] Preferably, the lubrication assembly includes a first plate, which is fixedly mounted on the surface of the fixed tube near the end face, and an opening tube is fixedly connected to the surface of the first plate.

[0014] Preferably, the lubrication assembly further includes a second plate, which is fixedly installed on the side of the perforated tube away from the first plate. There are two perforated tubes, which are distributed opposite each other. A sponge disc is fixedly connected between the two perforated tubes. The motor drives the connecting disc and the fixed tube to rotate as a whole. The lubricated metal wire passes through the equalizing component and the guiding component in sequence and is pulled into the inside of the stranding die for stranding. The equalizing component separates the reversed metal wires to avoid the metal wires from tangling and causing excessive resistance and breakage. In this device, multiple wire feeding components are spirally distributed on the surface of the fixed tube, and the telescopic motor vertically installs the wire feeding components.

[0015] Preferably, the locking mechanism includes an electric turntable, which is fixedly installed on the surface of the connecting plate near the edge. A spiral blade is fixedly connected to the output end of the electric turntable, and a telescopic cylinder is fixedly connected to the surface of the spiral blade. A limit block is fixedly connected to the output end of the telescopic cylinder.

[0016] Preferably, the anti-skid wire mechanism includes a fixed body, the end face of which is fixedly installed at the middle position of the lubrication component surface. A connecting pipe is fixedly connected to the side of the fixed body away from the lubrication component. A distribution component is fixedly connected to the surface of the connecting pipe. The metal wire on the surface of the wire feeding component is tangentially pulled. After the metal wire is fed, it passes through the lubrication component and is lubricated. The lubricated metal wire is pulled through the entire distribution component and the entire guide component into the interior of the stranding die. During this process, multiple metal wires converge from the circumference to the center. At this point, the metal wire experiences the greatest frictional resistance and is the most likely to break. The metal wire passes through the roller and the rotating roller. The roller and the rotating roller replace sliding friction with rolling friction, effectively reducing the frictional resistance of the metal wire.

[0017] Preferably, the anti-skid mechanism further includes a conical shell, the end face of which is fixedly installed at the end of the connecting pipe away from the fixed body, and a guide component is fixedly connected to the surface of the conical shell.

[0018] Preferably, the equalizing component includes a fixing sleeve, the inner side of which is fixedly installed on the outer surface of the connecting pipe, and a change guide plate is fixedly connected to one end of the fixing sleeve near the fixing body.

[0019] Preferably, the inner side of the reversing guide plate is rotatably connected to a roller, and the end of the fixed sleeve away from the fixed body is fixedly connected to an alignment guide plate. The inner side of the alignment guide plate is rotatably connected to a rotating roller. When the first plate and the second plate are installed opposite each other, the two perforated tubes clamp and align the sponge plate. The surface of the sponge plate has a circular hole, through which the metal wire passes and is in close contact with the inner side of the sponge plate. The surface of the sponge plate is coated with lubricating oil, and as the metal wire moves, its surface is evenly coated with lubricating oil. The metal wire passes through the reversing guide plate and the alignment guide plate. The opposing rollers make it difficult for the metal wire to directly contact the reversing guide plate when reversing.

[0020] Preferably, the conical shell has a concave surface, the guide assembly includes a sphere, the sphere is rotatably mounted on the conical shell near the concave surface, and a conical plate is fixedly connected to the surface of the conical shell.

[0021] Preferably, the guiding assembly further includes a connecting rod, the end face of which is fixedly mounted on the surface of the ball, and an inclined tube is fixedly connected to the end of the connecting rod away from the ball.

[0022] The working principle and beneficial effects of this invention are as follows:

[0023] 1. The rotating die equipment of the cable production frame stranding machine has multiple wire feeding components spirally arranged on the surface of the fixed tube. The multiple wire feeding components are separated by a barrier plate. The distance between the wire feeding components is the same. The limit plate limits the wire feeding components. As the connecting plate rotates intermittently, the electric turntable drives the spiral plate to rotate. The telescopic motor drives the wire feeding components to move vertically upward, which can load the wire feeding components onto the coil. This solves the problem that manual intervention is required to adjust the rotation angle when loading and unloading the coil, and the problem of not being able to achieve automated management of the wire feeding and coil conveying of the frame stranding machine.

[0024] 2. The rotating mold equipment of the cable production frame stranding machine drives the motor to drive the connecting plate to rotate as a whole. The fixed tube rotates at a certain angle evenly and intermittently. With the drive of the screw slide, multiple winding wheels are arranged in a spiral row at the position of multiple extension tubes. The metal wire is tangentially led out of the winding wheel to the first plate. When multiple metal wires pass through the first plate, the angle between each pair of metal wires is the same. Compared with the prior art, where the winding wheels are distributed side by side, the resistance between the metal wire and the equipment is smaller and less likely to break when the wire is led out.

[0025] 3. In the rotating die equipment of the cable production frame stranding machine, when the metal wire is unwinding, in order to prevent the unwinding assembly from loosening and being thrown out under the action of centrifugal force, the electric turntable drives the spiral blade to rotate, so that the spiral blade rotates and aligns with the extension tube. At this time, the telescopic cylinder is set opposite to the unwinding assembly. Through the rotation of the spiral blade, multiple telescopic cylinders and multiple unwinding assemblies quickly connect. The surface of the limit block rotates and engages with the inner side of the unwinding assembly. The unwinding assembly is not easy to loosen under the centrifugal force, and it will not interfere with the unwinding assembly when it is coiled.

[0026] 4. In the rotating die equipment of the cable production frame stranding machine, the metal wire passes through the inclined tube during the process of the metal wire to the stranding die. The metal wire gathers towards the center. With the rapid rotation of the connecting tube and the fixed body, the metal wire is prone to entanglement and impact when it deviates and shakes. In this device, the ball rotates on the concave surface to avoid the metal wire from breaking due to large frictional resistance between the metal wire and the conical shell. This solves the problem of the wire core being prone to jumping when guided to the stranding die, resulting in excessive single-wire stranding resistance.

[0027] 5. The rotating die equipment of the cable production frame stranding machine has rollers that rotate with the metal wires, effectively reducing frictional resistance. The limiting position of the rotating rollers also makes it difficult for the metal wires to come into frictional contact with the alignment guide plate. The metal wires with uniform lubrication on their surface have even less frictional resistance. Since the spiral distribution of the winding wheel on the surface of the fixed tube means that the metal wires are evenly spaced as they pass through the rotating rollers, the metal wires are less likely to collide or entangle with each other when rotating at high speed, making the metal wires more stable and less prone to breakage during the stranding process.

[0044] Example 1

[0045] Reference Figures 1-4 , Figure 7 As a first embodiment of the present invention, a rotary die device for a cable stranding machine is proposed, comprising a linear guide rail 1, a lead screw slide 2 fixedly connected to the output end of the linear guide rail 1, a telescopic motor 3 fixedly connected to the output end of the lead screw slide 2, a limit plate 4 fixedly connected to the output end of the telescopic motor 3, and two fixed platforms 5 fixedly connected to the side of the linear guide rail 1, and further comprising:

[0046] The wire coil fixing mechanism 6 is rotatably mounted on the inner side of the fixing platform 5. The wire coil fixing mechanism 6 is used for limiting and guiding the wire coil and lubricating the surface of the wire.

[0047] Locking mechanism 7 is fixedly installed on the inner side of wire reel fixing mechanism 6. Locking mechanism 7 is used for locking and limiting when the metal wire is wound and unwound.

[0048] Anti-skip wire mechanism 8 is fixedly installed at the middle position on the surface of the wire reel fixing mechanism 6. Anti-skip wire mechanism 8 is used to guide the traction and reversal of the metal wire after the wire is released.

[0049] The spool fixing mechanism 6 includes a connecting plate 61, which is rotatably mounted on the inner side of the fixing platform 5. A fixing tube 62 is fixedly connected to the surface of the connecting plate 61. An extension tube 63 and a barrier plate 64 are fixedly connected to the surface of the fixing tube 62 respectively. A wire feeding assembly 65 is fixedly connected to the inner side of the fixing tube 62. A lubrication assembly 66 is fixedly connected to the end of the fixing tube 62 away from the connecting plate 61.

[0050] The locking mechanism 7 includes an electric turntable 71, which is fixedly installed on the surface of the connecting plate 61 near the edge. A spiral blade 72 is fixedly connected to the output end of the electric turntable 71, and a telescopic cylinder 73 is fixedly connected to the surface of the spiral blade 72. A limit block 74 is fixedly connected to the output end of the telescopic cylinder 73.

[0051] In this embodiment, the fixed platform 5 provides rotational support for the connecting plate 61 and the lubrication component 66. The surface of the wire feeding component 65 is wound with metal wire. When the fixed tube 62 is driven to rotate, multiple metal wires are twisted into conductor strands. In the prior art, multiple winding wheels are arranged side by side, and the inclined upper plate method is used to align the multiple winding wheels. When the motor drives the fixed tube 62 to rotate, it is not easy to adjust the angle, so the operator needs to adjust it repeatedly. In this device, multiple wire feeding components 65 are spirally arranged on the surface of the fixed tube 62. The barrier plate 64 separates the multiple wire feeding components 65. The distance between the wire feeding components 65 is the same. The limiting plate 4 limits the wire feeding components 65. With the intermittent rotation of the connecting plate 61, the electric turntable 71 drives the spiral plate 72 to rotate. The telescopic motor 3 drives the wire feeding component 65 to move vertically upward, which can load the wire feeding component 65 onto the upper plate. This solves the problem that manual intervention is required to adjust the rotation angle when loading and unloading the upper plate, and the problem of not being able to realize the automated management of the upper plate loading and wire reel conveying of the frame stranding machine.

[0052] Example 2

[0053] Reference Figures 3-6 The wire feeding assembly 65 includes a drive motor 651, which is fixedly installed on the inner side of the fixed tube 62. The output end of the drive motor 651 is fixedly connected to an internal threaded sleeve 652. The wire feeding assembly 65 also includes a threaded tube 653, the surface of which is connected to the inner side of the internal threaded sleeve 652 by threads. A winding wheel 654 is fixedly connected to the end face of the threaded tube 653, and a locking hole 655 is provided on the surface of the winding wheel 654.

[0054] The lubrication assembly 66 includes a first plate 661, which is fixedly installed on the surface of the fixed tube 62 near the end face. An opening tube 662 is fixedly connected to the surface of the first plate 661. The lubrication assembly 66 also includes a second plate 663, which is fixedly installed on the side of the opening tube 662 away from the first plate 661. There are two opening tubes 662, which are distributed opposite each other. A sponge disc 664 is fixedly connected between the two opening tubes 662.

[0055] In this embodiment, the surface of the limiting disk 4 engages with the side of the winding wheel 654 near the locking hole 655. The linear guide rail 1 drives the lead screw slide 2 to move to a position directly below the drive motor 651. The telescopic motor 3 drives the limiting disk 4 and the winding wheel 654 to rotate and move upward. The threaded tube 653 is screwed into the inner side of the inner threaded sleeve 652. The winding wheel 654 is tightly engaged with the inner threaded sleeve 652 through the thread. The end face of the metal wire passes through the openings on the surfaces of the first plate 661 and the second plate 663. The surface of the fixing platform 5 is fixed. A drive motor is connected to drive the connecting disc 61 to rotate as a whole. The fixed tube 62 rotates at a certain angle evenly and intermittently. With the drive of the lead screw slide 2, multiple winding wheels 654 are arranged in a spiral arrangement at the positions of multiple extension tubes 63. The metal wire is tangentially led out of the winding wheels 654 to the first plate 661. When multiple metal wires pass through the first plate 661, the angle between each pair of metal wires is the same. Compared with the prior art, where the winding wheels are arranged side by side, the resistance between the metal wires and the equipment is smaller and less likely to break when the wires are led out.

[0056] Example 3

[0057] Reference Figure 3 , Figure 7 , Figure 8 The connecting plate 61 is rotatably mounted on the inner side of the fixed platform 5. A fixed tube 62 is fixedly connected to the surface of the connecting plate 61. An extension tube 63 and a barrier plate 64 are fixedly connected to the surface of the fixed tube 62 respectively. A wire feeding assembly 65 is fixedly connected to the inner side of the fixed tube 62. A lubrication assembly 66 is fixedly connected to the end of the fixed tube 62 away from the connecting plate 61.

[0058] The electric turntable 71 is fixedly installed on the surface of the connecting plate 61 near the edge. The output end of the electric turntable 71 is fixedly connected to a spiral blade 72. The surface of the spiral blade 72 is fixedly connected to a telescopic cylinder 73. The output end of the telescopic cylinder 73 is fixedly connected to a limit block 74.

[0059] The anti-skid cable mechanism 8 includes a fixed body 81, the end face of which is fixedly installed at the middle position of the surface of the lubrication component 66. A connecting pipe 82 is fixedly connected to the side of the fixed body 81 away from the lubrication component 66. A dividing component 84 is fixedly connected to the surface of the connecting pipe 82. The anti-skid cable mechanism 8 also includes a conical shell 83, the end face of which is fixedly installed at the end of the connecting pipe 82 away from the fixed body 81. A guiding component 85 is fixedly connected to the surface of the conical shell 83.

[0060] In this embodiment, the motor drives the connecting plate 61 and the fixed tube 62 to rotate as a whole. The lubricated metal wire passes through the equalizing component 84 and the guiding component 85 in sequence and is pulled into the inside of the stranding mold for stranding. The equalizing component 84 separates the reversed metal wires to prevent them from tangling and breaking due to excessive resistance. In this device, multiple wire feeding components 65 are spirally distributed on the surface of the fixed tube 62. The telescopic motor 3 vertically installs the wire feeding components 65. When the metal wire is fed, in order to prevent the wire feeding components 65 from loosening and being thrown out under the action of centrifugal force, the electric turntable 71 drives the spiral blade 72 to rotate, so that the spiral blade 72 rotates and aligns with the extension tube 63. At this time, the telescopic cylinder 73 is set opposite to the wire feeding components 65. Through the rotation of the spiral blade 72, multiple telescopic cylinders 73 quickly dock with multiple wire feeding components 65. The surface of the limiting block 74 rotates and engages with the inner side of the wire feeding component 65. The wire feeding component 65 is not easy to loosen under the centrifugal force, and it will not interfere with the wire feeding component 65 when it is loaded onto the coil.

[0061] Example 4

[0062] Reference Figures 8-10 The equal distribution component 84 includes a fixed sleeve 841, the inner side of which is fixedly installed on the outer surface of the connecting pipe 82. A reversing guide plate 842 is fixedly connected to one end of the fixed sleeve 841 near the fixed body 81. A roller 843 is rotatably connected to the inner side of the reversing guide plate 842. An alignment guide plate 844 is fixedly connected to one end of the fixed sleeve 841 away from the fixed body 81. A rotating roller 845 is rotatably connected to the inner side of the alignment guide plate 844.

[0063] The conical shell 83 has a concave surface 851 on its surface. The guide assembly 85 includes a ball 853, which is rotatably mounted on the conical shell 83 near the concave surface 851. A conical plate 852 is fixedly connected to the surface of the conical shell 83. The guide assembly 85 also includes a connecting rod 854, the end face of which is fixedly mounted on the surface of the ball 853. An inclined tube 855 is fixedly connected to the end of the connecting rod 854 away from the ball 853.

[0064] In this embodiment, the metal wire on the surface of the wire feeding assembly 65 is tangentially pulled. After the wire is fed, it passes through the lubrication assembly 66 and is lubricated. The lubricated wire is then pulled through the entire distribution assembly 84 and the entire guide assembly 85 to the inside of the stranding die. During this process, multiple metal wires converge from the circumference to the center. At this point, the metal wire experiences the greatest frictional resistance and is most prone to breakage. The metal wire passes through the roller 843 and the rotating roller 845. The roller 843 and the rotating roller 845 use rolling friction instead of sliding friction, effectively reducing the frictional resistance of the metal wire. During the process of the metal wire reaching the stranding die, it passes through the inclined tube 855 and converges towards the center. With the rapid rotation of the connecting tube 82 and the fixed body 81, the metal wire is prone to entanglement and impact when it deviates and shakes. In this device, the ball 853 rotates on the concave surface 851, avoiding the generation of large frictional resistance between the metal wire and the conical shell 83, which could lead to breakage. This solves the problem of excessive single-wire stranding resistance caused by wire skipping when the wire core is guided to the stranding die.

[0065] Example 5

[0066] Reference Figure 6 , Figure 9 The first plate 661 is fixedly installed on the surface of the fixed tube 62 near the end face. The surface of the first plate 661 is fixedly connected to the perforated tube 662. The lubrication assembly 66 also includes a second plate 663. The second plate 663 is fixedly installed on the side of the perforated tube 662 away from the first plate 661. There are two perforated tubes 662 and they are distributed opposite each other. A sponge disc 664 is fixedly connected between the two perforated tubes 662.

[0067] The inner side of the fixed sleeve 841 is fixedly installed on the outer surface of the connecting pipe 82. A reversing guide plate 842 is fixedly connected to the end of the fixed sleeve 841 near the fixed body 81. A roller 843 is rotatably connected to the inner side of the reversing guide plate 842. An alignment guide plate 844 is fixedly connected to the end of the fixed sleeve 841 away from the fixed body 81. A rotating roller 845 is rotatably connected to the inner side of the alignment guide plate 844.

[0068] In this embodiment, when the first plate 661 and the second plate 663 are installed opposite each other, the two perforated tubes 662 clamp and align the sponge disc 664. The surface of the sponge disc 664 has a circular hole. The metal wire passes through the circular hole and is in close contact with the inner surface of the sponge disc 664. The surface of the sponge disc 664 is coated with lubricating oil. As the metal wire moves, its surface is evenly coated with lubricating oil. The metal wire passes through the reversing guide plate 842 and the alignment guide plate 844. The opposing rollers 843 make it difficult for the metal wire to change direction during reversal. The guide plate 842 makes direct contact with the wire, and the roller 843 rotates with the wire to effectively reduce frictional resistance. The limiting function of the rotating roller 845 makes it difficult for the wire to rub against the alignment guide plate 844. The wire with a uniformly lubricated surface has even less frictional resistance. Since the winding wheel 654 is spirally distributed on the surface of the fixed tube 62, the wires are evenly spaced as they pass through the rotating roller 845, making it difficult for the wires to collide or entangle with each other when rotating at high speed. This makes the wires more stable and less prone to breakage during the stranding process.
