[0027] Example

[0028] Please refer to Figure 1 and Figure 2 As shown, this embodiment provides a multi-stranded wire rounding device including: a mounting seat 10 and a plurality of rounding components 20. The mounting seat 10 has a positioning hole 101; the plurality of rounding components 20 are mounted on the mounting seat 10 and are distributed along the circumference of the positioning hole 101, each group of rounding components 20 is two rounding components 20 arranged opposite to each other, the mounting seat 10 is located between the two rounding components 20 of each group of rounding components 20, each group of rounding components 20 has a rounding portion 21 arranged opposite to each other, the rounding portions 21 on the plurality of rounding components 20 are arranged in an interlaced and stacked manner, and the rounding portion 21 has an adjustable accommodation space 22, the accommodation space 22 corresponds to the positioning hole 101, and the accommodation space 22 is used to pass the stranded wire.

[0029] In this embodiment, a positioning hole 101 is opened in the middle of the mounting seat 10, and two roundness correction components 20 in each group of roundness correction components 20 are respectively arranged on both sides of the mounting seat 10, and the multiple groups of roundness correction components 20 are specifically three groups, such as Figure 2 As shown, one group is directly installed on the mounting base 10, and the other two groups of rounding components 20 are respectively provided with a first pad 102 and a second pad 103. The thickness of the first pad 102 is greater than that of the second pad 103, so as to achieve a stacking arrangement between multiple groups of rounding components 20, and then to achieve a stacking arrangement between the rounding parts 21 on multiple rounding components 20. Correspondingly, the accommodating spaces 22 on each group of rounding parts 21 are also stacked. The stranded wire passes through the three stacked accommodating spaces 22 and the positioning holes 101 on one side of the mounting base 10 and the three stacked accommodating spaces 22 on the other side in sequence. The multiple strands of the stranded wire are extruded in different directions for multiple times through the accommodating spaces 22 with a certain passing gap to complete the rounding processing of the multiple strands of the stranded wire.

[0030] Further, in some implementations of this embodiment, Figure 1 and Figure 2 As shown, there are included angles between the multiple groups of rounding components 20 .

[0031] In the present embodiment, the multiple groups of rounding components 20 are specifically three groups, and the angle between each group of rounding components 20 is 120°, and the rounding portion 21 of each rounding component 20 is at the same distance from the central axis of the positioning hole 101, thereby improving the uniformity of the rounding portion 21 in squeezing the stranded wires passing through the multiple accommodating spaces 22, effectively calibrating the multi-strand stranded wire bodies, and improving the roundness of the multi-strand stranded wire bodies.

[0032] Further, in some implementations of this embodiment, Figures 2 to 5 As shown, the circle calibration assembly 20 includes: a positioning block 201, two side plates 202, a rotating rod 203, a bottom plate 205, and a slider 207. The positioning block 201 is mounted on the mounting seat 10; the two side plates 202 are mounted on both sides of the positioning block 201 respectively; the rotating rod 203 has a rotating hole 204 on the side plate 202, and the rotating rod 203 is inserted into the rotating hole 204; the bottom plate 205 is mounted between the two side plates 202, and has a sliding groove 206 on the bottom plate 205; and the slider 207 is slidably mounted in the sliding groove 206.

[0033] In this embodiment, if Figure 3 and Figure 4 As shown, mounting holes are provided on both sides of the positioning block 201, two side panels 202 are installed on both sides of the positioning block 201 by screws, a fixing hole is provided at one end of the side panel 202 away from the positioning block 201, and the bottom panel 205 is installed between the two side panels 202 by screws. Figure 5 As shown, one end of the slider 207 has a protrusion that matches the cross section of the sliding groove 206. The protrusion abuts against the sliding groove 206 to limit the slider 207 from rotating relative to its central axis.

[0034] Further, in some implementations of this embodiment, Figures 2 to 5 As shown, the rounding part 21 includes: a fixed roller 211 and a sliding roller 212. The fixed roller 211 is disposed on the positioning block 201; the sliding roller 212 is disposed on the slider 207, and a receiving space 22 is formed between the sliding roller 212 and the fixed roller 211.

[0035] In this embodiment, the material of the fixed roller 211 and the sliding roller 212 can be an insulating material. The fixed roller 211 is inserted into the positioning block 201. A locking hole is provided on the side of the positioning block 201. The peripheral side of the fixed roller 211 is tightened by bolts to fix the relative position relationship between the fixed roller 211 and the positioning block 201. A locking hole is provided on the slider 207. The peripheral side of the sliding roller 212 is tightened by bolts to fix the relative position of the sliding roller 212 and the slider 207.

[0036] Further, in some implementations of this embodiment, Figures 2 to 5As shown, a rotating shaft hole 208 is opened on the slider 207 , and the rotating shaft hole 208 corresponds to the rotating hole 204 , and the rotating rod 203 is penetrated in the rotating shaft hole 208 and the rotating hole 204 .

[0037] In this embodiment, if Figure 3 and Figure 4 As shown, the central axis of the shaft hole 208 coincides with the central axis of the rotating holes 204 opened on the side plates 202 on both sides, and the rotating rod 203 passes through the rotating hole 204 on one side, the shaft hole 208, and the rotating hole 204 on the other side in sequence.

[0038] Further, in some implementations of this embodiment, Figures 3 to 5 As shown, the rotating rod 203 is in transmission connection with the slider 207 , and the rotating rod 203 is rotated to drive the slider 207 and the sliding roller 212 inserted in the slider 207 to slide along the sliding groove 206 .

[0039] In this embodiment, a thread is provided on the rotating rod 203, and a thread meshing with the rotating rod 203 is provided in the shaft hole 208. The rotating rod 203 is rotatably set on the two side plates 202. Two pin holes are provided on the rotating rod 203, and the two pin holes are respectively located on both sides of one side plate 202. The rotating rod 203 is limited to slide along its central axis by a pin column. The rotating rod 203 is rotated. Since the rotating rod 203 does not slide along the axis, the slider 207 is driven to slide in the sliding groove 206 along the axis direction of the rotating rod 203, so as to drive the sliding roller 212 to move relative to the fixed roller 211, so as to adjust the gap size of the accommodating space 22, thereby adapting to multiple strands of twisted wires with different wire diameters.

[0040] In summary, when a multi-strand stranded wire rounding device is used to round and calibrate the multi-strand stranded wire body, the stranded wire is guided to pass through the accommodating space 22 on the multiple groups of rounding components 20. The stranded wire body is effectively rounded through repeated squeezing of the multiple groups of fixed rollers 211 and the sliding rollers 212 to ensure the roundness of the wire body. In actual production, different multi-strand stranded wires need to be processed with different wire diameters. The rotating rod 203 is rotated to drive the sliding roller 212 to slide relative to the fixed roller 211 to adjust the size of the gap between each group of accommodating spaces 22 to adapt to the processing requirements of different wire diameters, thereby reducing the tedious steps of replacing rounding components 20 of different sizes, reducing the installation errors and limitations caused by repeated installation, and improving the processing quality and efficiency of the device.

[0041] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
