Description

Technical Field

[0001] The invention relates to the technical field of cable production, and in particular to a rotary die device of a frame stranding machine for cable production. Background Art

[0002] When the frame-type stranding machine is in use, multiple wire drums will be installed on the circumference of the stranding cage, and the position of the wire drums is required to ensure that the positions of the wire drums on the stranding cage are symmetrical with respect to the central axis of the stranding cage. This can make the distribution of the wire drums more uniform, which is conducive to unifying the wire supply situation of each wire drum and helping to improve the quality of the stranded wire. When the wire drums on the sides of the frame-type stranding machine are fixed, they are often clamped and fixed by a clamping mechanism. There is a certain error in their installation. Therefore, after the wire drums are installed, manual inspection is often required. Continuous grooves on the surface of the wire core are generally caused when the wire is pulled, the lubrication conditions of the wire pulling are deteriorated, and aluminum sticks to the surface. Discontinuous grooves may be caused by foreign matter sticking to the stranding die. The Chinese patent announcement number is: CN115762910B discloses "A frame stranding machine rotating mold device". In this patent, the length of the cable delivered to different positions of the stranding assembly is different in the same time by the wire feeder, and the reaction force is reduced by reducing the cable deformation, reducing the clamping force, and reducing the damage to the cable. The cable is wound on the first winding rod or the second winding rod. The rotation process of the first winding rod and the second winding rod releases the cable 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, and the wear and damage to the cable are small. The second winding rod is sleeved inside the first winding rod, reducing the volume of the wire feeder.

When the upper and lower reels are in place, manual adjustment of the rotation angle is required, and automated management of the upper and lower reels of the frame twisting machine cannot be achieved. In addition, the wire core is prone to wire jumping when it is guided to the twisting mold, resulting in excessive resistance to single-wire twisting. Summary of the invention

A sponge plate is fixedly connected to the position between the two perforated tubes, driving the motor to drive the connecting plate and the fixed tube to rotate as a whole. The lubricated metal wire passes through the equalizing assembly and the guide assembly in turn and is pulled into the interior of the stranding mold for stranding. The equalizing assembly separates the reversing metal wire to avoid entanglement between the metal wires, resulting in excessive resistance and breakage. In the device, a plurality of pay-off assemblies are spirally distributed on the surface of the fixed tube, and the telescopic motor vertically mounts the pay-off assemblies.

At this time, the friction resistance of the metal wire is the largest and it is also the position most likely to break. The metal wire passes through the roller and the rotating roller, and the roller and the rotating roller replace the sliding friction with rolling friction, which effectively reduces the friction resistance of the metal wire.

[0017] The working principle and beneficial effects of the present invention are: 1. The rotary die equipment of the cable production frame stranding machine has multiple pay-off components spirally arranged on the surface of the fixed tube. The barrier pieces separate the multiple pay-off components. The distances between the pay-off components are the same. The limit disk limits the pay-off components. With the intermittent rotation of the connecting disk, the electric turntable drives the spiral piece to rotate, and the telescopic motor drives the pay-off component to move vertically upward to put the pay-off component on the coil, which solves the problem of manual participation in adjusting the rotation angle when putting on and putting off the coil, and the inability to realize the automatic management of the coiling and wire coiling of the frame stranding machine.

[0018] 2. The rotary mold equipment of the frame stranding machine for cable production drives the motor to drive the connecting disk to rotate as a whole, and the fixed tube rotates evenly and intermittently at a certain angle. With the drive of the screw slide, multiple winding wheels are spirally arranged in sequence at the positions of multiple extension tubes, and the metal wire is tangentially led out of the winding wheel to the first plate body. When multiple metal wires pass through the first plate body, the angle between every two metal wires is the same. Compared with the prior art, the winding wheels are distributed side by side, and the resistance between the metal wire and the equipment is smaller when the metal wire is led out, and it is not easy to break.

[0019] 3. For the rotary die equipment of the frame stranding machine for cable production, 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 piece to rotate so that the spiral piece rotates and aligns with the extension tube. At this time, the telescopic cylinder and the unwinding assembly are arranged relatively to each other. Through the rotation of the spiral piece, multiple telescopic cylinders and multiple unwinding assemblies are quickly connected, and the surface of the limit block is rotationally engaged with the inner side of the unwinding assembly. The unwinding assembly is not easy to loosen under the centrifugal force, and will not be disturbed when the unwinding assembly is put on the reel.

[0020] 4. The rotary die equipment of the frame stranding machine for cable production, the metal wire passes through the inclined tube during the process of reaching the stranding die, and the metal wire gathers toward the center. With the rapid rotation of the connecting tube and the fixed body, the metal wire is prone to entanglement and collision when it deviates and shakes. The ball in the device rotates on the inner concave surface to avoid large friction resistance between the metal wire and the conical shell and prevent it from breaking, thus solving the problem of excessive single-wire stranding resistance caused by wire jump when the wire core is guided to the stranding die.

[0021] 5. The rotary die equipment of the frame stranding machine for cable production has rollers that rotate with the pulling of the metal wire, effectively reducing the friction resistance, and the limit of the rotating roller makes it difficult for the metal wire to have friction contact with the alignment guide disk. The metal wire with evenly lubricated surface makes the friction resistance smaller. Since the winding wheel is spirally distributed on the surface of the fixed tube, the unwinding metal wire passes through the rotating roller with uniform gaps, making it difficult for the metal wire to collide or entangle with each other when rotating at high speed, making the metal wire more stable and less likely to break during the stranding process.

In the prior art, multiple winding wheels are distributed side by side, and the multiple winding wheels are aligned by an inclined upper disk. It is not easy to adjust the angle when the motor drives the fixed tube 62 to rotate, so that the staff needs to adjust it repeatedly. In this device, multiple pay-off assemblies 65 are spirally arranged on the surface of the fixed tube 62, and the barrier plate 64 separates the multiple pay-off assemblies 65. The distances between the pay-off assemblies 65 are the same, and the limit disk 4 limits the pay-off assembly 65. With the intermittent rotation of the connecting disk 61, the electric turntable 71 drives the spiral sheet 72 to rotate, and the telescopic motor 3 drives the pay-off assembly 65 to move vertically upward to put the pay-off assembly 65 on the disk, which solves the problem that manual participation is required to adjust the rotation angle when putting on and putting off the disk, and the automatic management of the upper disk and the wire disk transportation of the frame stranding machine cannot be realized.

There are two perforated tubes 662 and they are distributed oppositely, and a sponge plate 664 is fixedly connected to the position between the two perforated tubes 662.

[0031] In this embodiment, the surface of the limit plate 4 is engaged with the side of the winding wheel 654 close to the locking hole 655, the linear guide rail 1 drives the screw slide 2 to move to the position directly below the driving motor 651, the telescopic motor 3 drives the limit plate 4 and the winding wheel 654 to rotate and move upward, the threaded tube 653 is screwed into the inner side of the internal threaded sleeve 652, the winding wheel 654 is tightly engaged with the internal threaded sleeve 652 through the thread, the end face of the metal wire passes through the openings on the surfaces of the first plate body 661 and the second plate body 663, and the surface of the fixed platform 5 is fixed A driving motor is connected, which is used to drive the connecting disk 61 to rotate as a whole, and the fixed tube 62 rotates evenly and intermittently at a certain angle. With the drive of the screw slide 2, multiple winding wheels 654 are spirally arranged in sequence at the positions of multiple extension tubes 63, and the metal wire is tangentially led out of the winding wheel 654 to the first plate body 661. When multiple metal wires pass through the first plate body 661, the angle between every two metal wires is the same. Compared with the prior art, the winding wheels are distributed side by side, and the resistance between the metal wire and the equipment is smaller when the metal wire is led out, and it is not easy to break.

[0032] Example 3 Reference Figure 3 , Figure 7 , Figure 8 The connecting plate 61 is rotatably mounted on the inner side of the fixed platform 5, the surface of the connecting plate 61 is fixedly connected to the fixing tube 62, the surfaces of the fixing tube 62 are respectively fixedly connected to the extension tube 63 and the blocking sheet 64, the inner side of the fixing tube 62 is fixedly connected to the wire release assembly 65, and the end of the fixing tube 62 away from the connecting plate 61 is fixedly connected to the lubrication assembly 66; The electric turntable 71 is fixedly installed on the surface of the connection plate 61 near the edge, the output end of the electric turntable 71 is fixedly connected to a spiral sheet 72, the surface of the spiral sheet 72 is fixedly connected to a telescopic cylinder 73, and the output end of the telescopic cylinder 73 is fixedly connected to a limit block 74; The anti-jumping wire mechanism 8 includes a fixed body 81, the end face position of the fixed body 81 is fixedly installed in the middle position of the surface of the lubrication component 66, the side of the fixed body 81 away from the lubrication component 66 is fixedly connected with a connecting pipe 82, and the surface of the connecting pipe 82 is fixedly connected with an equalizing component 84; the anti-jumping wire mechanism 8 also includes a conical shell 83, the end face of the conical shell 83 is fixedly installed at one end of the connecting pipe 82 away from the fixed body 81, and the surface of the conical shell 83 is fixedly connected with a guide component 85.

[0033] In this embodiment, the motor drives the connecting disk 61 and the fixed tube 62 to rotate as a whole, and the lubricated metal wire passes through the equalizing component 84 and the guide component 85 in turn and is pulled to the inside of the wire twisting mold for twisting. The equalizing component 84 separates the reversing metal wire to avoid entanglement between the metal wires and excessive resistance and breakage. In the device, multiple wire-releasing components 65 are spirally distributed on the surface of the fixed tube 62, and the telescopic motor 3 vertically installs the wire-releasing component 65. When the metal wire is released, in order to prevent the wire-releasing component 65 from loosening and being thrown out under the action of centrifugal force, the electric turntable 71 drives the spiral piece 72 to rotate so that the spiral piece 72 rotates and aligns with the extension tube 63. At this time, the telescopic cylinder 73 is arranged opposite to the wire-releasing component 65. Through the rotation of the spiral piece 72, multiple telescopic cylinders 73 are quickly connected with multiple wire-releasing components 65. The surface of the limit block 74 is rotatably engaged with the inner side surface of the wire-releasing component 65. The wire-releasing component 65 is not easy to loosen under the centrifugal force, and it will not cause the wire-releasing component 65 to be disturbed when it is on the disk.

The guide assembly 85 also includes a connecting rod 854, and the end face of the connecting rod 854 is fixedly installed on the surface of the sphere 853, and the end of the connecting rod 854 away from the sphere 853 is fixedly connected to an inclined tube 855.

[0035] In this embodiment, the metal wire on the surface of the pay-off assembly 65 is pulled tangentially, and after the metal wire is paid off, it passes through the lubrication assembly 66 and is lubricated. The lubricated metal wire is pulled through the entire equalizing assembly 84 and the entire guide assembly 85 to the interior of the stranding die. In this process, multiple metal wires gather from the circumference to the center. At this time, the friction resistance of the metal wire is the largest and it is also the position most likely to break. The metal wire passes through the roller 843 and the rotating roller 845. The roller 843 and the rotating roller 845 replace the sliding friction with rolling friction, which effectively reduces the friction resistance of the metal wire. In the process of the metal wire reaching the stranding die, it passes through the inclined tube 855, and the metal wire gathers toward the center. With the rapid rotation of the connecting tube 82 and the fixed body 81, the metal wire is easily entangled and collided when it deviates and shakes. The sphere 853 in the device rotates on the inner concave surface 851 to avoid the metal wire and the conical shell 83 from generating a large friction resistance and breaking, thereby solving the problem of excessive single-wire twisting resistance caused by wire jump when the wire core is guided to the twisting die.

[0036] Example 5 Reference Figure 6 , Fig. 9 The first plate 661 is fixedly mounted on the surface of the fixed tube 62 near the end surface, and the surface of the first plate 661 is fixedly connected with a perforated tube 662. The lubrication assembly 66 also includes a second plate 663, which is fixedly mounted on a side of the perforated tube 662 away from the first plate 661. There are two perforated tubes 662 and they are distributed oppositely. A sponge disc 664 is fixedly connected between the two perforated tubes 662. The inner side surface of the fixed sleeve 841 is fixedly installed on the outer surface of the connecting pipe 82, and the end of the fixed sleeve 841 close to the fixed body 81 is fixedly connected to a reversing guide plate 842, and the inner side surface of the reversing guide plate 842 is rotatably connected to a roller 843, and the end of the fixed sleeve 841 away from the fixed body 81 is fixedly connected to a positioning guide plate 844, and the inner side surface of the positioning guide plate 844 is rotatably connected to a rotating roller 845.

[0037] In this embodiment, when the first plate body 661 and the second plate body 663 are installed relative to each other, the two perforated tubes 662 clamp and align the sponge plate 664. The surface of the sponge plate 664 is provided with a circular hole. The metal wire passes through the circular hole and is in close contact with the inner side of the sponge plate 664. The surface of the sponge plate 664 is adsorbed 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 rollers 843 arranged opposite to each other make it difficult for the metal wire to change direction when reversing. The guide receiving disk 842 is in direct contact with the roller 843, which rotates with the pulling of the metal wire and effectively reduces the friction resistance. The limit of the rotating roller 845 makes it difficult for the metal wire to have friction contact with the positioning guide receiving disk 844. The metal wire with uniformly lubricated surface makes the friction resistance smaller. Since the winding wheel 654 is spirally distributed on the surface of the fixed tube 62, the unwinding metal wire passes through the rotating roller 845 with uniform gaps, which makes it difficult for the metal wire to collide or entangle with each other when rotating at high speed, making the metal wire more stable and not easy to break during the twisting process.

[0038] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it.
