Description

Technical Field

[0001] The invention mainly relates to the technical field of cable production, and in particular to a wire stranding device used for cable production. Background Art

[0002] Cable production is usually based on batch production, and the internal structure of the cable varies according to its purpose. In the protective layer and the insulating layer, the cable components such as the metal core, conductor, and metal wire need to be twisted together before they can be inserted into the protective layer. Twisting the wires of the cables (collectively referred to as cables) inside the cable is usually a complicated task. In particular, it is difficult to process different types and numbers of cable bundles. When processing different numbers of stranded wires at the same time, the strands may not be tightly twisted. In addition, the traditional stranding processing device will produce burrs on the stranded wires, which reduces the processing quality.

[0003] In the prior art, a Chinese patent with publication number CN112489889A discloses a wire twisting device for cable production, including a workbench, a fixed frame fixedly connected to one side of the upper surface of the workbench, a wire arrangement box fixedly connected to the top of the fixed frame, and a first wire arrangement hole, a second wire arrangement hole, a third wire arrangement hole, a fourth wire arrangement hole and a fifth wire arrangement hole are opened on one side of the wire arrangement box. In this patent, the wire laying roller of a single conductor can be placed in a slot on a fixed plate, and then the conductor is passed through the wire arrangement hole for wire arrangement, and the number of cable strands to be produced is selected, and the motor drives the twisting drum to rotate, so that multiple single conductors can be twisted into one strand. The first wire arrangement hole, the second wire arrangement hole, the third wire arrangement hole, the fourth wire arrangement hole and the fifth wire arrangement hole are set, so that the device can select different wire arrangement holes according to the number of cable strands to be produced, so that four to eight single conductors can be twisted into one strand.

[0004] Although the patent allows multiple wires to pass through the arrangement holes and finally twist into a strand, the patent sets multiple wire arrangement holes, which requires manual wire arrangement, which is more troublesome. In addition, the patent cannot adapt to the processing of different types of cables, and cannot perform burr removal on the twisted wire after processing. Summary of the invention

[0031] Working principle of the present invention: when in use, the main line 3 of the cable needs to be passed through the central axis 222, and straightened by winches at both ends, the metal wires of the inner circle are respectively wound on the bobs 219, and the conductor wires of the outer circle are respectively passed through the wire cones 223 according to the number of wire bundles required, and the ends of the metal wires and the conductor wire bundles are tightly attached to the main line 3, and the three are locked together by the locking sleeve 301 and tightened on the winch. The winch here uses the existing technology and will not be repeated here. At this time, the preparations are ready, and the motor 201 is started. The motor 201 transmits power in three directions.

[0032] The motor 201 drives the output gear 202 to rotate, the output gear 202 drives the transmission gear 203 to rotate, the transmission gear 203 drives the bevel gear 1 204 to rotate, the bevel gear 1 204 drives the bevel gear 2 205 to rotate, thereby driving the first transmission shaft 206 to rotate, and the first transmission shaft 206 drives the bevel gear 3 207 to rotate.

[0033] When the transmission gear 203 rotates, it drives the second transmission shaft 211 to rotate. The rotation of the second transmission shaft 211 drives the eccentric wheel 212 to rotate. When the eccentric wheel 212 rotates, it drives the first connecting rod 213 to rotate. The first connecting rod 213 will drive the sliding seat 214 to slide on the slideway 218. When the sliding seat 214 slides, it drives the second connecting rod 215 to rotate. The second connecting rod 215 drives the hinge plate 217 to slide back and forth on the mounting plate 101 through the connecting shaft 216.

[0034] When the bevel gear three 207 rotates, it forms a bevel gear match with the bevel gear four 230, driving the rotating disk 229 to rotate. When the rotating disk 229 rotates, it drives the lever 228 to rotate intermittently.

[0035] The lever 228 will drive the central shaft 222 to rotate. When the central shaft 222 rotates, it will drive the central gear 227 to rotate. The central gear 227 forms a gear match with the transmission gear 226 and the gear ring fixing frame 221 and drives three identical transmission gears 226 to rotate. The bobbin 219 installed on the transmission gear 226 will rotate. At the same time, the gear ring fixing frame 221 will rotate driven by the circular rotating shaft 225, and drive the central gear 227 to rotate as a whole. Therefore, the bobbin 219 will rotate and rotate the winding thread. The metal wires on the hammer 219 are respectively wound around the main line 3. When the circular rotating shaft 225 rotates, the hexagonal seat 224 will be driven to rotate. When the hexagonal seat 224 rotates, the wire cones 223 evenly installed along the outer periphery of the hexagonal seat 224 will rotate together. The conductor wires arranged on the wire cones 223 will be wound around the main line 3 at the same time and hinged. It should be noted that the winch used to wind the main line 3 is also moving synchronously at this time. The wire cones 223 are installed in a spiral arrangement to ensure that the wire bundle can be smoothly twisted.

[0036] When the tightening piece 217 moves back and forth in a circular motion, it will reciprocate at a certain angle around the main line 3. The tightening piece 217 is designed as a blade-type structure, the purpose of which is to again match the metal wire and the wire bundle wrapped around the main line 3, so that the wire bundle and the metal wire are twisted more tightly, and at the same time some uneven burrs can be removed.
