Description

Technical Field

[0001] The invention relates to the technical field of cable manufacturing, and in particular to a cable conductor twisting device. Background Art

[0002] In cable production, appropriate conductor materials such as copper, aluminum or aluminum alloy are selected according to the purpose and performance requirements of the cable. A twisting device is used in the twisting process. The twisting device refers to a number of single wires of the same diameter or different diameters, which are twisted together in a certain direction and according to certain rules by controlling the twisting parameters to form a whole twisted wire. Sometimes it is necessary to twist once and then twist the twisted conductor for the second time. In addition, the twisted wire core is much softer than a single wire core of the same diameter and has better bending performance.

[0003] A Chinese patent document with authorization announcement number CN117623002B discloses a cable twisting device, including: a support frame, a twisting disk, a wire roller, a unloading assembly and a loading assembly, the twisting disk is rotatably connected to the support frame, a first driving member is provided in the twisting disk, the first driving member is used to drive the twisting disk to rotate, the twisting disk is provided with a plurality of first positioning rods spaced apart along its circumference, a positioning disk is provided at the center of the twisting disk, the positioning disk is provided with a plurality of positioning holes spaced apart along its circumference, a twisting device is also provided next to the positioning disk, the wire roller is fitted on the first positioning rod, and a conductor is wound around the wire roller; the cable twisting device of the invention can unload the wire roller through the unloading assembly and load the wire roller through the loading assembly, thereby saving manpower and improving cable production efficiency.

[0004] In the process of twisting cable conductors, before starting twisting, the required total conductor length should be calculated based on the twisting pitch and the number of twisted layers to ensure that there is enough margin to handle the last section of twisting. When the twisting is nearly completed and the last section is twisted, the wire ends are separated from the stranding drum and there is a large gap between the stranding drum and the stranding seat. Therefore, the last section needs to be twisted together using other machines or manually, or the last section needs to be cut off, which is troublesome or easy to cause material waste. Summary of the invention

[0005] The invention provides a cable conductor twisting device, aiming to solve the problem in the related art that it is difficult to twist the last section when twisting the cable by twisting equipment.

[0006] The cable conductor twisting device comprises a support frame, a twisting drum, a conductor seat and a twisting seat, wherein the conductor seat comprises:

[0007] A mounting seat, the mounting seat is slidably mounted at the center of the capstan drum, and a one-way damping member is installed between the mounting seat and the capstan drum;

[0008] A plurality of guide wheel seats 1 are arranged in a circular array and are slidably mounted on the edge of the mounting seat, an elastic member 1 is installed between the guide wheel seat 1 and the mounting seat, and a guide wheel seat 2 is rotatably mounted on the capstan corresponding to one position of the guide wheel seat;

[0009] A plurality of guide wheels are arranged in a circular array and rotatably mounted on a mounting seat;

[0010] A connecting seat is detachably mounted on the left side of the mounting seat, a plurality of guide wheel seats 3 are slidably arranged in a circular array on the connecting seat, an elastic member 2 is installed between the connecting seat and the guide wheel seat 3, and the guide wheel seat 3 cooperates with the guide wheel;

[0011] A clutch mechanism and a buckle assembly are installed on the mounting seat. When the guide wheel seat 1 contacts the guide wheel seat 2, the clutch mechanism restricts the rotation of the guide wheel, and the buckle assembly opens, so that the mounting seat can slide left and right relative to the capstan.

[0012] The effect is that when the wire is twisted, the wire wheel is installed on the twisting drum, the wire end is inserted between the guide wheel seat one and the guide wheel seat two, then passes through the guide wheel and the guide wheel seat three, and finally passes through the twisting seat, and then the mounting seat is slid in the direction close to the twisting drum, so that the guide wheel seat one and the guide wheel seat two clamp the wire, and at the same time, the buckle assembly fixes the mounting seat on the twisting drum, and then the twisting drum rotates, so that the wires are twisted together. When twisted to the last section, one of the wire sections detaches from the guide wheel seat one, and the clutch mechanism limits the rotation of the guide wheel to clamp the wire end. At the same time, the buckle assembly is opened and no longer limits the movement of the mounting seat to the right. At this time, when twisting, the mounting seat moves to the right, so that the last section of the wire enters the twisting seat, and at the same time, the one-way damping member increases the resistance encountered by the mounting seat during movement, thereby providing suitable tension for the twisting of the last section of the wire. This arrangement can conveniently twist the last section.

[0013] Preferably, the clutch mechanism includes a trigger component and a connecting ring rotatably mounted on the mounting seat, a through hole is opened at the axis of the guide wheel, the guide wheel is sleeved on the connecting ring, a clamping block 1 is arranged on the connecting ring at equal intervals, and a clamping block 2 is arranged in the through hole, when the guide wheel seat 1 contacts the guide wheel seat 2, the trigger component causes the connecting ring to rotate, and the clamping block 1 abuts against the clamping block 2, thereby limiting the rotation of the guide wheel, which has the effect that: when the wire detaches from the guide wheel seat 1, the trigger component causes the connecting ring to rotate, and the rotation of the connecting ring causes the clamping block 1 to abut against the clamping block 2, thereby limiting the rotation of the guide wheel and clamping the wire end.

[0014] Preferably, the trigger component is a trigger rod fixedly connected to the top of the guide wheel seat, and the connecting ring is provided with an inclined surface. The trigger rod abuts against the inclined surface. When the trigger rod moves to the left, the connecting ring rotates. The effect is that when the wire detaches from the guide wheel seat, the trigger rod drives the connecting ring to rotate, thereby limiting the rotation of the guide wheel.

[0015] Preferably, the buckle assembly includes a buckle installed on a connecting ring, and a slot matching the buckle is provided on the capstan. When the guide wheel seat one is in contact with the guide wheel seat two, the buckle disengages from the slot. The effect is that when the guide wheel seat one is in contact with the guide wheel seat two, the connecting ring rotates to disengage the buckle from the slot, thereby allowing the connecting ring and the connecting seat to move to the right.

[0016] Preferably, the connecting seat and the mounting seat are connected by an adjusting bolt, which has the effect of adjusting the distance between the connecting seat and the mounting seat by adjusting the adjusting bolt, thereby passing the wire between the guide wheel and the guide wheel seat three.

[0017] Preferably, the elastic member 1 and the elastic member 2 are both spring sheets.

[0018] Preferably, a plurality of guide rods are fixedly mounted on the mounting seat, a guide sleeve matched with the guide rods is provided on the wire drum, and the one-way damping member is arranged in the guide sleeve.

[0019] Preferably, the one-way damping element includes a friction plate connected to the guide sleeve at one end, the friction plate consists of a bent section and a straight section, the bent section is elastic and gradually approaches the guide rod from the right end to the left end, and the straight section is in contact with the guide rod.

[0020] By adopting the above technical solution, the beneficial effects of the present invention are as follows:

[0021] When the last section is twisted, after one section of the wire is separated from the guide wheel seat one, the guide wheel seat one moves to the left with the trigger rod, and the guide wheel seat one contacts the guide wheel seat two. The bottom end of the trigger rod slides along the inclined surface, thereby causing the connecting ring to rotate. The rotation of the connecting ring causes the clamping block one to abut against the clamping block two, thereby limiting the rotation of the guide wheel and thus clamping the wire end of the wire. At the same time, the rotation of the connecting ring causes the buckle to disengage from the clamping slot, thereby no longer limiting the movement of the mounting seat to the right. At this time, when twisting, the mounting seat moves to the right, thereby allowing the last section of the wire to enter the twisting seat. At the same time, the one-way damping member increases the resistance to the movement of the mounting seat, thereby providing suitable tension for the twisting of the last section of the wire. This arrangement can conveniently twist the last section and avoid manual twisting or material waste. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0034] like Figure 1 As shown, the cable conductor twisting device includes a support frame, a twisting drum 1, a conductor seat 2 and a twisting seat 3. A driving device (not shown in the figure) for driving the twisting drum 1 to rotate is installed on the support frame. Multiple wire wheels are installed on the twisting drum 1. Multiple wires pass through the conductor seat 2 and enter the twisting seat 3 to complete twisting. The twisting seat 3 is also a twisting mold.

[0035] like Figure 1-Figure 8As shown, the conductor seat 2 includes a mounting seat 21, a plurality of guide wheel seats 22, a plurality of guide wheels 23, a connecting seat 24, a clutch mechanism 25 and a buckle assembly 26. The mounting seat 21 is roughly a regular polygon, and the number of sides is the same as the number of the guide wheel seats 22. A plurality of guide rods 211 are fixedly mounted on the mounting seat 21, and a guide sleeve 13 adapted to the guide rod 211 is provided on the stranding drum 1. A one-way damping member 11 is provided in the guide sleeve 13, so that when the mounting seat 21 moves away from the stranding drum 1, the one-way damping member 11 is provided in the guide sleeve 13. The damping member 11 applies resistance to the guide rod 211, an elastic member 221 (such as a spring sheet) is installed between the guide wheel seat 22 and the mounting seat 21, and a guide wheel seat 2 12 is rotatably installed on the winding drum 1 corresponding to the guide wheel seat 22. The guide wheel seat 22 cooperates with the guide wheel seat 2 12, and the wire passes through the two. Pressure is applied to the wire through the elastic member 221 and the guide wheel seat 22, so that the wire maintains a certain tension when twisted, and a plurality of guide wheels 23 are arranged in a circular array and are rotatably installed on the mounting seat 21.

[0036] The shape of the connecting seat 24 on the left-view projection plane is also a regular polygon. The connecting seat 24 is connected to the mounting seat 21 by a plurality of adjusting bolts. The spacing between the connecting seat 24 and the mounting seat 21 is changed by rotating the adjusting bolts, thereby changing the distance between the guide wheel 23 and the guide wheel seat three 241. A plurality of guide wheel seats three 241 are slidingly arranged in a circular array on the connecting seat 24. An elastic member two 242 (such as a spring sheet) is installed between the connecting seat 24 and the guide wheel seat three 241. The guide wheel 23 cooperates with the guide wheel seat three 241. The clutch mechanism 25 and the buckle assembly 26 are installed on the mounting seat 21. When the guide wheel seat one 22 contacts the guide wheel seat two 12, the clutch mechanism 25 limits the rotation of the guide wheel 23, and the buckle assembly 26 opens, so that the mounting seat 21 can slide left and right relative to the winding drum 1, so that the mounting seat 21 moves to the right to feed the last section of the wire.

[0037] like Figure 8 and Fig. 9 As shown, the one-way damping member 11 includes a friction plate connected to the guide sleeve 13 at one end, and the friction plate is composed of a bent section and a straight section. The bent section is elastic and gradually approaches the guide rod 211 from the right end to the left end, and the straight section is in contact with the guide rod 211. Therefore, when the guide rod 211 slides to the right relative to the guide sleeve 13, the friction plate exerts a greater pressure on the guide rod 211, so the guide rod 211 is subjected to a greater resistance. When the guide rod 211 slides to the left relative to the guide sleeve 13, the guide rod 211 moves along the inclination direction of the friction plate, thereby moving the friction plate, so that the friction plate exerts a smaller pressure on the guide rod 211, so the guide rod 211 is subjected to a smaller resistance when it is reset, thereby facilitating reset.

[0038] like Figure 4 , Figure 5 and Figure 7 As shown, the clutch mechanism 25 includes a trigger component and a connecting ring 251 rotatably mounted on the mounting seat 21, the guide wheel 23 is sleeved on the connecting ring 251, and a first block 2511 is arranged at equal intervals on the circumferential surface of the connecting ring 251, and an inclined surface 2512 is provided on the right side of the connecting ring 251, and a through hole is provided at the axis of the guide wheel 23, and a second block 231 is arranged in the through hole. In the initial state, the first block 2511 and the second block 231 are staggered with each other on the left projection plane, and the trigger component is A trigger rod 252 is fixedly connected to the top of the guide wheel seat 22, and the trigger rod 252 is against the inclined surface 2512. When the wire is separated from the guide wheel seat 22, the guide wheel seat 22 moves to the left with the trigger rod 252, so that the guide wheel seat 22 contacts the guide wheel seat 2, so that the bottom end of the trigger rod 252 slides along the inclined surface 2512, and then the connecting ring 251 rotates. The connecting ring 251 rotates to make the block 1 2511 and the block 2 231 abut against each other, thereby limiting the rotation of the guide wheel 23 and clamping the wire end.

[0039] like Figure 7 and Figure 8 As shown, the buckle assembly 26 includes a buckle 261 and a slot 262. The buckle 261 is fixedly mounted on the connecting ring 251. The buckle 261 is L-shaped. A through hole is provided in the middle of the winding drum 1. The slot 262 is opened on the hole wall of the through hole. One end of the buckle 261 can pass through the slot 262. Then the buckle 261 is rotated so that one end of it abuts against the left side of the buckle 261, thereby limiting the connecting ring 251 from moving rightward relative to the winding drum 1. When the guide wheel seat 1 22 contacts the guide wheel seat 2 12, the connecting ring 251 rotates so that the left end of the buckle 261 is separated from the winding drum 1. Then the buckle 261 can pass through the slot 262, thereby no longer limiting the connecting ring 251 from moving rightward relative to the winding drum 1.

[0040] Working principle: When the wire is twisted, the wire wheel is installed on the twisting drum 1, the wire head is inserted between the guide wheel seat 1 22 and the guide wheel seat 2 12, then passes through the guide wheel 23 and the guide wheel seat 3 241, and finally passes through the twisting seat 3, and then the mounting seat 21 is slid toward the twisting drum 1, so that the guide wheel seat 1 22 and the guide wheel seat 2 12 clamp the wire, and at the same time, the connecting ring 251 is rotated to make the buckle 261 enter the slot 262, so that the mounting seat 21 is fixed on the twisting drum 1, and then the adjusting bolt is rotated to make the connecting seat 24 and the mounting seat 21 close to each other, so that the guide wheel 23 and the guide wheel seat 3 241 clamp the wire, and then the twisting drum 1 is rotated by the driving device, so that the wires are twisted together. When the last section is twisted, one section of the wire is separated from the guide wheel seat 1. After 22, the guide wheel seat 1 22 moves to the left with the trigger rod 252, the guide wheel seat 1 22 contacts the guide wheel seat 2 12, and the bottom end of the trigger rod 252 slides along the inclined surface 2512, thereby causing the connecting ring 251 to rotate. The connecting ring 251 rotates to cause the clamping block 1 2511 to abut against the clamping block 231, thereby limiting the rotation of the guide wheel 23 and clamping the wire end of the wire. At the same time, the connecting ring 251 rotates to cause the buckle 261 to disengage from the clamping groove 262, thereby no longer limiting the rightward movement of the mounting seat 21. At this time, when twisting, the mounting seat 21 moves to the right, thereby causing the last section of the wire to enter the twisting seat 3. At the same time, the one-way damping member 11 increases the resistance to the movement of the mounting seat 21, thereby providing a suitable tension for the twisting of the last section of the wire. This arrangement allows the last section to be twisted conveniently.

[0041] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
