Description

Technical Field

[0001] This application relates to the technical field of specialized equipment or methods for manufacturing conductors or cables, and specifically to an additional stranding mechanism. Background Technology

[0002] Patent application document with publication number CN110473671A describes a wire splitting and stranding mechanism, the specific working principle of which is as follows: Initial positioning and fixing of the additional line: The upper finger clamp first clamps the additional line from the additional line outlet hole of the additional line outlet cutting structure, and then pulls the additional line to the additional line fixing seat and fixes it; then, the additional line fixing seat clamps the additional line and simultaneously completes the descent and backward movement, and finally stops in the waiting position.

[0003] T1 cable reel splitting and multi-stage twisting: First, the upper splitting finger clamps clamp, place, and secure the T1 cable reel. Then, the upper splitting finger clamps hold the copper wires on the T1 cable reel and splits them backward, selecting the two longest wires. These are then twisted with the additional wire. After twisting the longest wires with the additional wire, the following steps are performed sequentially: The two second-longest wires are fed to the third twisting hook to complete the twisting; the two third-longest wires are fed to the third twisting hook to further twist with the already twisted second-longest wires; the upper splitting finger clamps the two shortest wires from the lower splitting finger clamps and feeds them to the second twisting hook; subsequently, the additional wire holder moves forward and rises upward, ensuring the additional wire and the shortest wire are very close, and finally, the second twisting hook completes the twisting of the shortest wire and the additional wire.

[0004] However, although the wire splitting and twisting mechanism enables the additional wire to be twisted with the two longest wires and the two shortest wires respectively at both ends, the additional wire cannot be inserted between the two longest wires or the two shortest wires because the clamping position of the additional wire is below all the wires on the coil, which in turn has an adverse effect on the final performance of the product.

[0016] Reference Figure 1-5 As shown, an embodiment of this application is proposed. The additional stranded wire mechanism described in this embodiment includes: Clamping assembly 10 is used to secure the coil; The first additional wire fixing seat 20 is disposed on the right side of the clamping assembly 10; The second additional wire fixing seat 30 is disposed on the left side of the clamping assembly 10; An auxiliary wire outlet hole 40 and an auxiliary wire cutting assembly 50 are disposed on the right side of the first auxiliary wire fixing seat 20; The lower wire splitter 60 is disposed on the front side of the clamping assembly 10 and can move closer to or away from the clamping assembly 10. The lower wire splitter 60 is used to clamp the two bundles of copper wires of the coil and distribute the two bundles of copper wires vertically. The upper parting finger clamp 70 has two pairs of clamping fingers 71 spaced apart. It is positioned above the clamping component 10 via a moving component 72. The moving component 72 is used to drive the upper parting finger clamp 70 to perform three-dimensional movement and horizontal rotation. The lifting platform 80 is located on the right side in front of the clamping assembly 10 and can move in the left and right direction. The lifting platform 80 is used to support the additional line. The first stranded wire assembly 90 has a first stranded wire hook 91, which is disposed at the first auxiliary wire fixing seat 20. The second stranded wire assembly 100 has a second stranded wire hook 101, which is disposed at the second additional wire fixing seat 30.

[0017] The workflow of the additional stranded wire structure described in this embodiment is as follows: 1. Coil fixing and copper wire pre-clamping: The T1 coil is placed in the clamping assembly 10, and the two bundles of copper wires are distributed vertically and clamped and fixed; the lower branch finger clamp 60 opens, the upper branch finger clamp 70 clamps the copper wire and moves forward to its front side, and then the lower branch finger clamp 60 closes to clamp the copper wire, completing the initial positioning of the copper wire.

[0018] 2. For example Figure 3As shown, the additional wire threading and positioning: After the upper wire clip 70 clamps the free end of the additional wire through the additional wire outlet hole 40, the moving component 72 drives the two pairs of clamping fingers 71 to rotate to a left-right distribution. The two pairs of clamping fingers 71 respectively include a first pair of clamping fingers 711 and a second pair of clamping fingers 712 distributed to the right of the first pair of clamping fingers 711. After the two pairs of clamping fingers 71 clamp the additional wire through the first additional wire fixing seat 20, they move to above the lifting platform 80, and the lifting platform 80 is located at the two pairs of clamping fingers. Between the fingers 71, the first pair of clamping fingers 711 opens to place the additional wire on the lifting platform 80; then, the two pairs of clamping fingers 71 and the lifting platform 80 move to the left in sync, the lifting platform 80 supports the additional wire as it passes through the two bundles of copper wire, so that both bundles of copper wire are between the two pairs of clamping fingers 71, the second pair of clamping fingers 712 releases the additional wire and is positioned above the copper wire; the splitting fingers move to the left so that both pairs of clamping fingers 71 are on the left side of the copper wire, the second pair of clamping fingers 712 re-clamps the additional wire, and the lifting platform 80 moves to the right to reset; 3. Fixing and cutting the additional wire: After the upper wire finger clamp 70 continues to move to the left and passes the second additional wire fixing seat 30, the first additional wire fixing seat 20 and the second additional wire fixing seat 30 clamp the two ends of the additional wire, and the additional wire cutting component 50 cuts the additional wire, thus completing the fixing of the two ends of the additional wire.

[0019] 4. Splitting and twisting the lines: Rotate the upper splitting finger clip 70 to the front-back direction, and work with the lower splitting finger clip 60 to split the lines: First, feed the two longest lines into the hook of the first twisting hook 91, and release the two pairs of first auxiliary line fixing seats 20. The first twisting hook 91 completes the twisting of the auxiliary lines with the longest lines; then feed the two shortest lines into the second twisting hook 101, release the second auxiliary line fixing seat 30, and the second twisting hook 101 completes the twisting of the auxiliary lines with the shortest lines.

[0020] Specifically, the first stranding assembly 90 has a first stranding hook 91, which is used to strand the auxiliary wire and copper wire held on the first auxiliary wire fixing seat 20; the second stranding assembly 100 has a second stranding hook 101, which is used to strand the auxiliary wire and copper wire fixed on the second auxiliary wire fixing seat 30.

[0021] The upper splitting finger clamp 70 and the lower splitting finger clamp 60 work together to first separate the two longest lines. Then, the upper splitting finger clamp 70 clamps the two longest lines and feeds them into the first twisting hook 91. The first additional line fixing seat 20 is released, and the first twisting hook 91 twists the additional line and the two longest lines. After the upper splitting finger clamp 70 and the lower splitting finger clamp 60 separate the two shortest lines, the upper splitting finger clamp 70 clamps the two shortest lines and feeds them into the second twisting hook 101. The second additional line fixing seat 30 is released, and the second twisting hook 101 twists the additional line and the two shortest lines.

[0022] By employing the cooperation of a lifting platform 80 and an upper wire-splitting finger clamp 70 with two pairs of clamping fingers 71, the auxiliary wire is precisely passed through the two bundles of copper wires through synchronous leftward movement, ensuring that the auxiliary wire can be inserted between the two copper wires for twisting. This solves the problem in the original technology where the twisting position of the auxiliary wire and the copper wire affects the performance of the coil.

[0023] The moving component can drive the upper wire separating finger clamp 70 to move in three dimensions and rotate horizontally. Combined with the coordinated action of the lower wire separating finger clamp 60, it realizes the orderly separation and precise delivery of copper wires.

[0024] In this embodiment, the clamping assembly 10 includes a receiving seat 11, a fixing arm 12, and a telescopic member 13. The cable receiving seat 11 is provided with a receiving groove for receiving the cable. One end of the fixing arm 12 is rotatably mounted on the receiving seat 11. The telescopic end of the telescopic member 13 can be rotatably connected to the fixing arm 12.

[0025] The fixed arm 12 presses the coil by rotating, and the pressure is evenly distributed, which can prevent the coil from shifting during the splitting and twisting process and ensure processing accuracy.

[0026] Preferably, the system also includes a wire feeding mechanism 110 for feeding additional wires to the additional wire outlet hole 40.

[0027] When the upper wire finger clamp 70 moves while holding the free end of the auxiliary wire, the wire feeding mechanism 110 continuously feeds the auxiliary wire to ensure a stable supply of the auxiliary wire.

[0028] Specifically, the wire feeding mechanism 110 includes a fixed bracket 111, a motor 112, a conveying wheel 113, a pressing wheel 114, and a pressing cylinder 115. The conveying wheel 113 is rotatably mounted on the fixed bracket 111. The motor 112 is connected to the conveying wheel 113 and is used to drive the conveying wheel 113 to rotate. The pressing wheel 114 is rotatably disposed on the fixed bracket 111 and can move on the fixed bracket 111 to approach or move away from the conveying wheel 113. The pressing cylinder 115 is used to push the pressing wheel 114 to press the conveying wheel 113.

[0029] When the upper wire-separating finger clamp 70 moves while holding the free end of the auxiliary wire, the clamping cylinder 115 drives the clamping roller 114 to move downward, clamping the auxiliary wire between the conveying roller 113 and the clamping roller 114. The motor 112 drives the conveying roller 113 on the fixed bracket 111 to rotate. With the help of the friction of the wheel set, the auxiliary wire is fed to the auxiliary wire outlet hole 40 as the conveying roller 113 rotates. After the auxiliary wire is threaded, the clamping cylinder 115 drives the clamping roller 114 to move upward, releasing the auxiliary wire. The clamping structure of the conveying roller 113 and the clamping roller 114 prevents the auxiliary wire from slipping or shifting, ensuring the wire feeding length and positional accuracy, and providing a stable foundation for subsequent threading and twisting.

[0030] Preferably, the fixed bracket 111 is provided with a receiving groove 1111, and the two opposite side walls of the fixed bracket 111 are provided with sliding grooves that communicate with the receiving groove 1111. A slidable mounting bracket 116 is installed on the fixed bracket 111. The clamping wheel 114 is disposed in the receiving groove 1111. The axles at both ends of the clamping wheel 114 pass through the sliding grooves and are both connected to the mounting bracket 116. The clamping cylinder 115 is used to push the mounting bracket 116 so that the clamping wheel 114 clamps the conveying wheel 113, ensuring that the clamping wheel 114 always maintains a corresponding position with the conveying wheel 113 and stably clamps the auxiliary line.

[0031] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
