Description

Technical Field

[0001] This utility model relates to the technical field of conductor expansion devices, and in particular to a wire distributor for producing sparsely wound conductors. Background Technology

[0002] As is well known, in recent years, with the continuous growth of the power industry and electrical demand, in order to improve power transmission capacity and reduce losses, sparse-wound expanded diameter conductors are selected. The production of sparse-wound expanded diameter conductors requires stranding equipment. This equipment can strand multiple conductors, such as bare copper wire and aluminum-clad copper conductors, into stranded conductors, or stranded conductors into bundled conductors. It is a widely used piece of equipment by wire and cable manufacturers. Generally, stranding equipment is equipped with a wire divider.

[0003] Chinese patent CN222914481U describes a wire separator for a cage winch, comprising a rotating shaft, a disc, a wire guide mechanism, and a telescopic mechanism. The disc is connected to the rotating shaft, and the disc surface has a circular hole. The wire guide mechanism is disposed within the circular hole, and the telescopic mechanism is connected to the disc via a fixing member. However, in actual use, the following problems still exist:

[0004] In the process of loosely wound expansion conductors, the tension of the conductor is usually adapted and balanced by the spring in the telescopic mechanism. However, when the conductor tension decreases, the elastic potential energy generated by the spring compression is released instantaneously, which impacts the single conductor, causing damage to the single conductor and affecting the quality of the loosely wound expansion conductor. At the same time, when adapting to the tension, the single conductor is lifted up, which increases the bending angle of the single conductor, affecting the smoothness of the single conductor passing through the wire hole and destroying the uniformity of stranding.

[0005] Therefore, a splitter for producing sparsely wound, expanded diameter conductors is proposed. Utility Model Content

[0006] The purpose of this utility model is to overcome the shortcomings of the prior art, solve the problems mentioned in the background art, and provide a wire distributor for the production of sparsely wound expanded diameter conductors.

[0007] To achieve the aforementioned objective, this utility model adopts the following technical solution:

[0008] A wire distributor for producing sparsely wound, expanded-diameter conductors includes a wire distributor body and a rotating shaft. The wire distributor body is fixedly connected to the rotating shaft via a fixing member. The wire distributor body has a plurality of sliding grooves arranged radially along the wire distributor body and evenly distributed circumferentially around the central axis of the wire distributor body. An adaptive single-wire tension angle adjustment component is provided within each sliding groove. The adaptive single-wire tension angle adjustment component includes a sliding block, a single-wire angle adaptation component, and a single-wire tension adaptation component. The two sides of the sliding block are located within the sliding groove and are slidably connected to the wire distributor body via sliding members. The sliding block has a bearing circular hole. The single-wire angle adaptation component is located within the bearing circular hole and connected to the inner wall of the sliding block. The top end of the single-wire tension adaptation component is connected to the bottom end of the sliding block, and the bottom end of the single-wire tension adaptation component is located within the sliding groove and connected to the bottom end of the inner wall of the wire distributor body.

[0009] The single-line angle adaptation component includes a guide ball, ball bearings, and a stabilizer. There are at least four ball bearings, and the number of ball bearings is even. The guide ball has a center hole. The sliding block has an annular groove, which is circumferentially arranged on the inner wall of the sliding block around the central axis of the bearing hole. The outer wall of the guide ball has an arc-shaped groove along the axial direction of the hole. The number of arc-shaped grooves corresponds to the number of ball bearings, and the arc-shaped grooves are evenly distributed circumferentially on the outer wall of the guide ball around the central axis of the hole. One end of each ball bearing is located within the arc-shaped groove and abuts against the guide ball, while the other end of each ball bearing is located within the annular groove and abuts against the sliding block. The ball bearings are connected by the stabilizer.

[0010] The stabilizer includes stabilizer rings and arc-shaped rods. The number of stabilizer rings corresponds to the number of balls. The inner wall of the stabilizer ring is slidably connected to the balls. The outer walls of two adjacent stabilizer rings are fixedly connected by the arc-shaped rods.

[0011] The single-line tension adaptation component includes a limiting tube, a support column, a spring, and a potential energy release component. The bottom end of the limiting tube is fixedly connected to the bottom end of the inner wall of the splitter disc body. The bottom end of the support column is located inside the limiting tube and is connected to the inner wall of the limiting tube through the potential energy release component. The bottom end of the spring is located inside the limiting tube and is fixedly connected to the bottom end of the inner wall of the splitter disc body. The top end of the spring abuts against the lower surface of the support column. The top end of the support column is rotatably connected to the bottom end of the sliding block.

[0012] The potential energy release component includes a sliding column, and the inner wall of the limiting tube is provided with a spiral groove. One end of the sliding column is fixedly connected to the outer wall of the supporting column, and the other end of the sliding column is located in the spiral groove and slidably connected to the limiting tube.

One end of the bracket is located below the bearing circular hole and is fixedly connected to the sliding block. The other end of the bracket is rotatably connected to the rotating wheel. The position of the rotating wheel corresponds to the position of the wire hole.

[0014] The rotating wheel is provided with an annular groove, which is circumferentially arranged on the outer wall of the rotating wheel around the central axis of the rotating wheel.

[0015] Compared with the prior art, this utility model has the following beneficial effects: The guide ball drives the rolling balls to rotate around the central axis of the annular groove, eliminating internal torque in the guide ball and preventing excessive twisting due to excessive internal torque, thus improving the quality of the sparsely wound expanded diameter guide ball; Through the cooperation of the support column, limiting tube, sliding column, spring, and spiral groove, the support column rotates around the axis while pushing the sliding block upwards, adapting to the tension of the guide ball and preventing the spring from instantaneously releasing elastic potential energy when the tension decreases, which could damage the guide ball and reduce its quality, thus improving the quality of the sparsely wound expanded diameter guide ball; By having two sets of rolling balls alternately driven to rotate within the arc-shaped groove, the rotation of the guide ball adapts to the angle from the wire hole to the wire twisting point, improving the smoothness of passing through the wire hole, avoiding the decrease in smoothness due to increased bending angle when adapting to wire tension, thus improving the uniformity of twisting, and further improving the quality of the sparsely wound expanded diameter guide ball.

[0028] like Figure 1-4 As shown, a wire distributor for producing sparsely wound, expanded diameter conductors includes a wire distributor body 1 and a rotating shaft 2. The wire distributor body 1 is fixedly connected to the rotating shaft 2 by a fixing member.

[0029] like Figure 2 , Figure 3 , Figure 6 , Figure 7 and Figure 9 As shown, the single-line angle adaptation component includes a guide ball 7, ball bearings 8, and a stabilizer. There are at least four ball bearings 8, and the number of ball bearings 8 is even. The guide ball 7 has a wire hole 9 at its center. The sliding block 5 has an annular groove 10. The annular groove 10 is circumferentially arranged on the inner wall of the sliding block 5 around the central axis of the bearing hole 6.

The number of arc-shaped grooves 11 corresponds to the number of ball bearings 8, and the arc-shaped grooves 11 are evenly distributed circumferentially around the central axis of the wire hole 9 on the outer wall of the guide ball 7. One end of the ball bearing 8 is located in the arc-shaped groove 11 and abuts against the guide ball 7, and the other end of the ball bearing 8 is located in the annular groove 10 and abuts against the sliding block 5. The ball bearings 8 are connected to each other through the stabilizer.

[0030] like Figure 2 , Figure 3 , Figure 6 , Figure 7 and Figure 9 As shown, the stabilizer includes a stabilizer ring 12 and an arc-shaped rod 13. The number of stabilizer rings 12 corresponds to the number of balls 8. The inner wall of the stabilizer ring 12 is slidably connected to the balls 8. The outer walls of two adjacent stabilizer rings 12 are fixedly connected by the arc-shaped rod 13.

[0031] like Figure 3 , Figure 4 and Figure 8 As shown, the single-line tension adaptation component includes a limiting tube 14, a support column 15, a spring 16, and a potential energy release component. The bottom end of the limiting tube 14 is fixedly connected to the bottom end of the inner wall of the splitter body 1.

The bottom end of the spring 16 is located inside the limiting tube 14 and is fixedly connected to the bottom end of the inner wall of the splitter body 1. The top end of the spring 16 abuts against the lower surface of the support column 15. The top end of the support column 15 is rotatably connected to the bottom end of the sliding block 5.

[0032] like Figure 3 , Figure 4 , Figure 5 and Figure 8 As shown, the potential energy release component includes a sliding column 17, and the inner wall of the limiting tube 14 is provided with a spiral groove 18. One end of the sliding column 17 is fixedly connected to the outer wall of the support column 15, and the other end of the sliding column 17 is located in the spiral groove 18 and is slidably connected to the limiting tube 14.

[0033] like Figure 1 and Figure 4As shown, the sliding block 5 is provided with a single-line auxiliary component, which includes a bracket 19 and a rotating wheel 20. One end of the bracket 19 is located below the bearing circular hole 6 and is fixedly connected to the sliding block 5. The other end of the bracket 19 is rotatably connected to the rotating wheel 20. The position of the rotating wheel 20 corresponds to the position of the wire hole 9.

[0034] like Figure 1 and Figure 4 As shown, the rotating wheel 20 is provided with an annular groove 21, which is circumferentially arranged on the outer wall of the rotating wheel 20 around the central axis of the rotating wheel 20.

[0035] The work process is as follows:

[0036] S1. In use, connect the rotating shaft 2 to the stranding machine, and place the wires to be stranded onto the annular groove 21 of the rotating wheel 20 in sequence, and then pass them through the wire hole 9 to strand the wires together. After adjusting the tension of the wires, fix the splitter body 1 to the rotating shaft 2 with the fixing piece. Start the stranding machine. The rotating shaft 2 drives the splitter body 1 to rotate, causing the wires to strand together. When the friction between the wires and the wire ball 7 causes the internal torque of the wires to be too large due to the rotation of the splitter body 1, the wire ball 7 drives the ball 8 to rotate around the central axis of the annular groove 10 to eliminate the internal torque of the wires. This prevents excessive twisting caused by excessive internal torque of the wires, which would lead to a decrease in the quality of the loosely wound expanded diameter wires and improve the quality of the loosely wound expanded diameter wires.

[0037] S2, during use, when the tension of the conductor decreases, the spring 16 inside the limiting tube 14 releases elastic potential energy, and the spring 16 applies an upward thrust to the support column 15. At this time, the support column 15 rotates around the axis along the trajectory of the spiral groove 18 through the cooperation of the sliding column 17 and the spiral groove 18, and pushes the sliding block 5 upward simultaneously. This adapts to the tension of the conductor while preventing the spring 16 from releasing elastic potential energy instantaneously when the tension decreases, thus preventing the conductor from being damaged and causing a decrease in the quality of the loosely wound expanded diameter conductor, thereby improving the quality of the loosely wound expanded diameter conductor.

[0038] S3, during use, when the wire tension decreases, the spring 16 releases elastic potential energy, which pushes the wire ball 7 upward through the support column 15, sliding block 5, and ball bearings 8. This causes the wire bending angle to increase, reducing the smoothness of the wire passing through the wire hole 9. Due to the change in the wire bending angle, the squeezing force on the wire ball 7 also changes. At this time, according to the pressure change, two symmetrical balls bearings 8 abut against the annular groove 10 to form an axis, while the other two symmetrical balls bearings 8 slide relative to the wire ball 7 within the arc-shaped groove 11 around the transverse central axis of the wire ball 7. The ball bearing 8, near the sliding block 5, abuts against the annular groove 10, causing the lead ball 7 to rotate. During the entire pressure change process, the two sets of balls 8 slide alternately along the arc-shaped groove 11 under the action of the lead pressure difference, causing the lead ball 7 to rotate. The rotation of the lead ball 7 adapts to the angle of the lead from the wire hole 9 to the lead stranding point, thereby improving the smoothness of passing through the wire hole 9. This avoids the reduction in the smoothness of passing through the wire hole 9 due to the increased bending angle of the lead when adapting to the lead tension, which would reduce the uniformity of the stranding of the loosely wound expanded diameter lead, thus improving the quality of the loosely wound expanded diameter lead.

[0039] By adding a bracket 19 to the sliding block 5, the support of the wire by the rotating wheel 20 on the bracket 19 is used to cooperate with the wire ball 7 to change the wire angle and improve the stability of the device. The annular groove 21 on the rotating wheel 20 can further limit the left and right sway of the wire and improve the stability of the device. The relative position of the ball 8 is limited by the cooperation of the stabilizing ring 12 and the arc rod 13, which improves the stability of the wire ball 7 during the dynamic adjustment process.
