[0002] A coil usually refers to a ring-shaped wire winding, which means that the wires are wound one by one and the wires are insulated from each other. Depending on the insulation tube, the coil can be hollow or contain an iron core or a magnetic powder core. As a common component in electrical engineering, it has many uses and types. The first step in coil processing is to choose the right wire. Commonly used wires include copper wire, aluminum wire, silver wire, etc. The thickness and hardness of the wire will affect the performance of the coil.
[0003] Wire twisting is a key step in the coil processing process. It is the process of twisting multiple single wires together according to certain rules to improve the transmission quality of the wire, reduce signal interference and reduce electromagnetic radiation.
[0004] However, the traditional wire stranding device for coil processing has a relatively simple structure when in use, and cannot flexibly adapt to the wire stranding operation of different numbers of conductors according to the coil processing requirements, which leads to confusion in the arrangement of the wire bundles during the wire stranding process, affecting the quality of the finished coil.

Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.
[0021] The utility model discloses a wire twisting device for coil processing, which is mainly used in scenarios where a conventional wire twisting device for coil processing has a relatively simple structure when in use and cannot flexibly adapt to wire twisting operations with different numbers of conductors according to coil processing requirements, thereby causing the arrangement of wire bundles to be easily confused during the wire twisting process, affecting the quality of the finished coil.
[0022] Reference Figure 1 , Figure 2 and Figure 3 A wire stranding device for coil processing comprises a base plate 1, a mounting box 7 mounted on the top outer wall of the base plate 1, a fixed seat 5 and a wire unwinding mechanism, an annular track is arranged on the top outer wall of the fixed seat 5, a wire stranding drum 12 is slidably connected to the inner wall of the annular track, a driving gear 11 is connected to the inner wall of the fixed seat 5 through a bearing, a motor 10 is arranged on the outer wall of one side of the fixed seat 5, one end of the output shaft of the motor 10 is connected to the outer wall of one side of the driving gear 11, a tooth groove is arranged on the circumferential outer wall of the wire stranding drum 12, the tooth grooves are meshed with the tooth grooves, and a multi-layer circumferentially distributed wire hole 13 is arranged on the outer wall of the wire stranding drum 12,
[0023] Specifically, the wires to be twisted can be passed through the corresponding wire holes 13 through the provided twisting drum 12. If the number of wires is large, the wire holes 13 distributed in the outer layer are selected, and if the number of wires is small, the wire holes 13 in the inner layer are selected. In addition, according to the coil production requirements, the corresponding arrangement order and twisting direction can be selected. The motor 10 drives the driving gear 11 to rotate, and with the cooperation of the driving gear 11 and the tooth groove, the twisting drum 12 is driven to rotate at a uniform speed.
[0024] Among them, the number of wire holes 13 located on the twisting drum 12 increases from the inside to the outside, and the number of wire holes 13 at the most central position of the twisting drum 12 is one. By controlling the equidistant wire holes 13, the wires can be made tighter during the twisting process, and the single wire hole 13 at the central position can be used for special twisting methods such as concentric twisting.
[0025] Reference Figure 1 and Figure 2In a preferred embodiment, the wire-releasing mechanism includes a plurality of limit seats 2 arranged on one side of the top outer wall of the substrate 1, the plurality of limit seats 2 are staggeredly distributed in two rows, and a wire roller 3 is sleeved on the outer wall of the limit seat 2.
[0026] Specifically, by adopting a staggered two-layer arrangement, it is ensured that the number of limit seats 2 is sufficient, and the dispersion of the wires when multiple limit seats 2 are used at the same time is avoided, and the confusion of the wire twisting process is avoided.
[0027] Among them, symmetrical mounting rods 4 are provided on both sides of the top outer wall of the base plate 1, and the same guide cross bar 8 is installed on the top of the two mounting rods 4. The top outer wall of the guide cross bar 8 is provided with equidistantly distributed threading grooves 9, and both ends of the threading grooves 9 are set as rounded structures.
[0028] It should be noted that the wire threading groove 9 on the guiding cross bar 8 can be used to further divert and guide the wires released by the wire-releasing mechanism to avoid a large number of wires from being tangled during the twisting process. At the same time, the rounded corner structure of the wire threading groove 9 can effectively protect the wires and avoid scratching the surface of the wires during the diversion and guiding process.
[0029] Reference Figure 1 , Figure 4 and Figure 5 In a preferred embodiment, a winding device is provided inside the installation box 7, and the winding device is used to wind up the wire after being twisted by the winding drum 12.

When the two meet and squeeze into contact, the outer ring protrusion 19 will exert an extrusion force on the inner ring protrusion 20, and this extrusion force can drive the three movable blocks 14 to move centripetally at the same time, shrinking the guide holes formed between the three movable blocks 14, so as to adjust to adapt to the different diameters of the wire harness after twisting, and ensure the orderly and stable introduction of the wire harness after twisting.
[0031] Among them, a connecting block 17 is provided on one side outer wall of the knob ring 16, and a fastening rod 18 is threadedly connected to one side outer wall of the connecting block 17. After the knob ring 16 is adjusted to a suitable position, the fastening rod 18 on one side of the connecting block 17 can be rotated to limit it, so that the knob ring 16 is locked in a suitable position.
[0032] Working principle: When in use, install the wire roller 3 that needs to be twisted on the limit seat 2, then lead out the free end of the wire on the wire roller 3, pull one end of it to disperse through the threading groove 9 on the guide cross bar 8, then select the appropriate wire hole 13 to pass through the twisting drum 12, and finally introduce it to the winding device inside the installation box 7 through the connector 6. After the preparation is completed and before starting to twist the wire, adjust the frequency of rotation of the winding device and the twisting drum 12 to achieve precise matching, and then the motor 10 drives the driving gear 11 to rotate, and under the cooperation of the driving gear 11 and the tooth groove, the twisting drum 12 is driven to rotate the twisted wire at a uniform speed.
