Description

Technical Field

[0001] This application relates to the field of stranding machine technology, specifically a modular adjustable stranding machine stranding mechanism. Background Technology

[0002] Stranding machines are core equipment in the manufacturing of cables, optical cables, and metal wires. By stranding multiple single wires into a uniformly structured strand, they directly affect the mechanical and electrical properties of the wires. With the increasing demand for high-precision, high-strength wires in fields such as new energy and aerospace, traditional stranding mechanisms, due to their fixed structure and limited parameter adjustment range, are unable to meet the requirements of multi-specification, small-batch, and customized production, becoming a bottleneck for technological upgrading in the industry.

[0003] Existing stranding mechanisms mostly adopt a one-piece rigid design, relying on mechanical transmission to achieve stranding action. Adjusting the pitch or tension requires changing the mold or manual intervention, which is inefficient and has poor compatibility. Its tension control relies on mechanical friction or gravity counterweight, which has insufficient dynamic accuracy and is prone to uneven stranding or even wire breakage. At the same time, the equipment has low versatility, and enterprises need to purchase multiple machines to adapt to different wires, which increases production costs.

[0004] Faced with the urgent need for flexible and intelligent production in the high-end manufacturing sector, there is a pressing need for a modular, adjustable stranding mechanism that can break through the constraints of traditional technologies through structural reconstruction and intelligent control. Such innovations must balance rapid parameter adjustment, multi-material compatibility, and high-precision dynamic control to improve production efficiency, reduce energy consumption, support customized production of high-value-added wires, and drive the industry's transformation towards high-end manufacturing. Utility Model Content

[0017] 1. This application achieves rapid adjustment of stranding parameters through a split modular design, such as a sliding arc slider, an annular boss with positioning holes, and a detachable wire harness mounting bracket. Operators only need to insert the stud with the head into the positioning hole to complete the stepless adjustment of pitch and stranding angle without changing molds or stopping the machine to disassemble parts. The changeover time is shortened, and the flexibility and efficiency of multi-specification wire production are significantly improved.

[0018] 2. The linkage adjustment of the bar guide rail and rack supports precise adjustment of the cable reel height and radial position. With the expandable number of arc sliders, it is compatible with wire diameters ranging from ultra-fine wires (0.1mm) to thick cables (10mm). A single device can cover the production needs of various materials (copper, aluminum, alloy) and stranding layers, reducing the equipment purchase cost for enterprises.

[0019] 3. The combination of hollow spindle and bearing support ensures mechanical stability under high-speed rotation and reduces wire vibration; the power system of motor + gear transmission provides uniform torque output, and combined with the adjustable damping design of wire harness mounting bracket, it achieves indirect optimization of stranding tension, greatly improves stranding uniformity and reduces wire breakage rate.

An annular groove 2 is provided in the middle of the outer side of the annular bracket 9, and an annular boss 1 is provided on both the left and right edges of the annular bracket 9. Positioning holes 3 are evenly distributed in an annular pattern on the annular boss 1.

[0028] Specifically, the hollow spindle 5 and spokes 8 are connected to achieve lightweight and high-speed adaptation, while the annular groove 2 and positioning hole 3 provide a basic structure for modular adjustment, ensuring rapid positioning and multi-parameter adjustment.

[0029] The inner side of the annular groove 2 is slidably connected to at least one arc-shaped slider 17. The left and right ends of the outer side of the arc-shaped slider 17 are provided with baffles 18. The baffles 18 are set close to the outer side of the annular boss 1. The baffles 18 are threadedly connected to a headed stud 16 through a threaded through hole on its outer side. The end of the headed stud 16 is inserted into the positioning hole 3.

[0030] Specifically, the insertion design of the arc-shaped slider 17 and the annular groove 2 enables stepless adjustment. The position of the arc-shaped slider 17 can be quickly locked by the headed stud 2 16, which significantly simplifies the adjustment process of pitch and angle and improves changeover efficiency.

[0031] The outer side of the arc-shaped slider 17 is equipped with a strip guide rail 7, and a height-adjustable slider 14 is installed on the strip guide rail 7. The outer side of the slider 14 is rotatably connected to a mounting shaft 11, and a wire harness mounting bracket 12 is provided at the end of the mounting shaft 11. A cable reel 13 is provided on the wire harness mounting bracket 12.

[0032] Specifically, the combination of the strip rail 7 and the adjustable slider 14 supports multi-dimensional adjustment of the cable reel height and radial position, adapting to different wire diameters and stranding layer requirements, and enhancing equipment compatibility.

[0033] Furthermore, a bearing support 10 is installed on the outer side of the hollow spindle 5.

The driving gear of the gear transmission pair is sleeved on the hollow main shaft 5, and the driven gear of the transmission box 4 is connected to the output shaft of the motor 6.

[0036] Specifically, the gear transmission pair provides smooth power output, avoids the slippage problem of traditional belt drives, and improves the accuracy of twisting tension control.

[0037] Furthermore, the central axis of the annular support 9 coincides with the central axis of the hollow main shaft 5.

[0039] Furthermore, the number of positioning holes 3 is thirty-six, and the thirty-six positioning holes 3 are evenly distributed in a ring on the outer side of the annular boss 1.

[0040] Specifically, the densely distributed positioning holes enable fine adjustment of the stranding angle at the 1° level, meeting the customized production needs of high-precision wires.

[0041] Furthermore, the outer surface of the annular boss 1 is provided with annular scale lines.

[0042] Specifically, the circular scale provides visual parameter calibration, helping operators quickly determine the installation angle of slider 14.

[0043] Furthermore, the outer side of the strip guide rail 7 is provided with at least one strip groove, and a rack is laid inside the strip groove. The outer side of the slider 14 is threadedly connected with a headed stud 15, and the end of the headed stud 15 is inserted into the rack groove in a corresponding manner.

[0044] Specifically, after the position of slider 14 is adjusted, the position of slider 14 can be fixed by screwing the stud 15 into the tooth groove of the rack.

[0045] Furthermore, the wire harness mounting bracket 12 includes a U-shaped bracket, on the inner side of which a material shaft is detachably mounted, and the cable reel 13 is sleeved on the material shaft.

[0046] Specifically, the detachable material shaft facilitates the replacement of cable reel 13, and the material shaft is fixed to the U-shaped frame with bolts.

[0047] In use: When using, the number of arc-shaped sliders 17 can be installed on the ring bracket 9 according to the number of strands of the cable as needed. After the arc-shaped sliders 17 are evenly distributed in the ring groove 2, the arc-shaped sliders 17 are fixed on the ring bracket 9 by the headed stud 2 16.

[0048] After adjusting the height of slider 14, the position of slider 14 is fixed by locking the head stud 15, and the cable roll 13 is then sleeved and installed onto the wire harness mounting bracket 12.

[0049] After the cable reel 13 is installed and fixed, the end of the cable is passed through the external wire twisting mold. When twisting the cable, the motor 6 drives the hollow spindle 5 to rotate, and the hollow spindle 5 drives multiple cable reels 13 to rotate synchronously to release the cable.
