[0031] Embodiment: as shown in Figures 1-6 The wire winding limiting device is characterized by comprising a support 1 and two groups of arc-shaped clamping blocks 2, the two groups of arc-shaped clamping blocks 2 are mirror image arranged, the arc-shaped clamping blocks 2 are slidingly assembled with the support 1 and are used for moving close to or away from each other, the central angle of the arc-shaped clamping blocks 2 is less than or equal to 180°, when the two groups of arc-shaped clamping blocks 2 move close to each other, the two groups of arc-shaped clamping blocks 2 form a winding space 201, and the winding space 201 is circularly arranged.

[0032] The two groups of arc-shaped clamping blocks 2 are mirror image arranged structures, that is, the centers of the two groups of arc-shaped clamping blocks 2 coincide, after the copper wire slides off from the wire feeding mechanism of the wire drawing machine and falls into the winding space 201, the winding of the copper wire is completed under the limiting action of the two groups of arc-shaped clamping blocks 2, after the winding is completed, the two groups of arc-shaped clamping blocks 2 move away from each other, since the central angle of the arc-shaped clamping block 2 is less than or equal to 180°, after moving away from each other, an opening is formed, which is convenient for the axial threading and fixing of the coiled copper wire, so as to perform the unloading, when the copper wire coil is unloaded, it does not need to be unloaded together with the arc-shaped clamping block 2, which solves the problem of the integrated winding cage cylindrical structure design, is convenient for taking out the coiled copper wire, improves the work efficiency, at the same time, solves the problem of occupying the transfer or storage space of the integrated winding cage, saves space, and reduces the warehouse cost.

[0033] In order to further improve the unloading difficulty of the copper wire coil, the embodiment further comprises a receiving plate 3 located below the two groups of arc-shaped clamping blocks 2, the cross-sectional area of the receiving plate 3 is greater than or equal to the cross-sectional area of the winding space 201, by arranging the receiving plate 3, the copper wire lead enters the winding space 201, under the action of its own weight, falls onto the receiving plate 3, and sequentially falls and stacks to complete the winding, so that the coiled copper wire is fixed on the receiving plate 3, by moving the receiving plate 3, the copper wire coil is moved away from the winding station, avoiding the friction between the copper wire coil and the bottom surface of the support 1 or the ground when directly moving the copper wire coil, so as to avoid the bottom layer of the copper wire coil being worn and affecting the use, and ensure the quality of the copper wire coil.

[0034] In terms of the specific structure of the sliding assembly of the arc-shaped clamping block 2 and the support 1, the embodiment further comprises a push cylinder 4, the fixed end of the push cylinder 4 is connected with the support 1, the pushing end of the push cylinder 4 is connected with the side of the arc-shaped clamping block 2 away from the winding space 201, and the push cylinder 4 is located below the middle part of the arc-shaped clamping block 2.

Since the axial height of the copper wire in the winding space 201 increases as the winding of the copper wire increases, the stress on the lower part of the arc-shaped clamping block 2 is greater. By locating the push cylinder 4 below the middle part of the arc-shaped clamping block 2, the shape retention of the winding space 201 can be effectively ensured. Of course, the arc-shaped clamping block 2 has rigidity, and only when the pushing action of the push cylinder 4 is designed below the middle part of the arc-shaped clamping block 2, the stress structure can be better optimized, and the shape retention of the winding space 201 can be improved.

[0035] In order to improve the smoothness of the sliding of the arc-shaped clamping blocks 2, so that the arc-shaped clamping blocks 2 move along a straight line when they are close to each other, the embodiment further comprises a plurality of groups of guide rods 5, the support 1 is provided with guide holes 101 for sliding assembly with the guide rods 5, one end of the guide rod 5 is assembled with the arc-shaped clamping block 2, the other end of the guide rod 5 slides in the guide hole 101, and the axis of the guide rod 5 is arranged in parallel with the axis of the pushing end of the pushing cylinder 4. By adding the structure of the guide rod 5 and the guide hole 101, the deviation problem that may occur during the sliding of the arc-shaped clamping block 2 is solved, the straight-line movement of the two groups of arc-shaped clamping blocks 2 is ensured, and the mutual approach or mutual separation is realized, thereby improving the sliding precision and stability of the arc-shaped clamping block 2.

[0036] In terms of the specific structural arrangement of the guide rod 5, since the outer wall of the arc-shaped clamping block 2 is arranged in an arc shape, when a plurality of groups of guide rods 5 are arranged, if the guide rods 5 are directly connected with the outer wall of the arc-shaped clamping block 2, the welding connection is difficult, the connection stability is poor, and the sliding extension distances of the guide rods 5 and the guide holes 101 are uneven. In order to solve the above technical problems, the embodiment further comprises a support plate 6, the guide rod 5 is provided with four groups, the four groups of guide rods 5 are connected at four end corners of the support plate 6, the pushing end of the pushing cylinder 4 is connected at the center of the support plate 6, and the side of the support plate 6 away from the pushing cylinder 4 is connected with the outer top wall of the arc-shaped clamping block 2. It is worth mentioning that an arc-shaped part is arranged at the connection between the support rod and the arc-shaped clamping block 2, and the arc-shaped part is arranged in matching with the outer ring wall of the arc-shaped clamping block 2.

[0037] In order to facilitate the mutual separation of the two groups of arc-shaped clamping blocks 2 to form a suitable opening space for taking out the copper wire roll, and to better limit the copper wire when the two groups of arc-shaped clamping blocks 2 are close to each other, in terms of the specific structural design of the central angle of the arc-shaped clamping block 2, the central angle of the arc-shaped clamping block 2 is 105°±5°, preferably 105°. By designing the central angle of the arc-shaped clamping block 2, the unloading operation space of the copper wire roll is optimized, the worker can easily take out the copper wire roll, the operation flexibility and efficiency are improved, and the copper wire limiting effect is ensured, and the neatness and stability of the copper wire during the winding process are improved.

[0038] In order to facilitate the copper wire from the wire drawing machine wire release mechanism, better into the winding space 201, therefore, need to be close to the spinning mechanism at the arc block 2 is provided with a guide structure, the embodiment also includes several groups of guide bar 7, guide bar 7 is connected to the top wall of the arc block 2, and the guide bar 7 is inclined to the side away from the winding space 201, through the inclined guide bar 7, the top of the winding space 201 forms the flared guide structure, the guide bar 7 is guided to avoid the copper wire from the wire drawing machine wire release mechanism, falling to the outside wall of the arc block 2, improve the reliability and stability of copper wire winding.

[0039] Because the top wall of the guide bar 7 is in contact with the copper wire, it will produce wear and tear, so it needs to be thickened, and at the same time, it also needs to ensure that the guide bar 7 has a certain elastic deformation capacity, so as to guide the copper wire from the wire release mechanism, so as to play a better guiding role, therefore, the guide bar 7 needs to be designed as a split structure, in the specific structure design of the guide bar 7, the guide bar 7 includes a contact part 701 and a connecting part 702, the connecting part 702 is used to connect the contact part 701 and the top wall of the arc block 2, the diameter of the contact part 701 is greater than that of the connecting part 702, and the connecting part 702 is arranged in a wave shape. Through the split structure design of the guide bar 7, the wave-shaped connecting part 702 has sufficient elastic deformation capacity while maintaining strength, improving the guiding effect, and prolonging the service life of the guide bar 7.

[0040] In order to ensure that the guide bar 7 can better guide the copper wire, the contact part 701 and the top wall of the arc block 2 form an included angle a, the included angle a is 115°±5°, preferably, the included angle a is 115°, which improves the guiding precision and ensures the smoothness of the copper wire during winding.

[0041] Because the copper wire has a high temperature after drawing, the copper wire still has a certain temperature during winding, in order to facilitate the copper wire to effectively dissipate heat during winding, the outer ring wall of the arc block 2 is provided with a plurality of through cooling holes 202, the plurality of cooling holes 202 are equidistantly arranged along the circumferential direction and the axial direction of the arc block 2, and the plurality of cooling holes 202 are equidistantly arranged. Through the equidistant arrangement of the plurality of cooling holes 202, the copper wire wound in the winding space 201 is prevented from being exposed to the outer wall of the arc block 2 through the cooling holes 202, thereby avoiding the problem of winding difficulty, and the plurality of cooling holes 202 can improve the air circulation efficiency and thus improve the heat dissipation effect.

[0042] Since the arc-shaped clamping block 2 is provided with a plurality of groups of heat dissipation holes 202, the rigidity of the arc-shaped clamping block 2 is weakened. In order to ensure the rigidity of the arc-shaped clamping block 2, the embodiment further comprises a vertical rod 8 which is connected to the arc-shaped clamping block 2 in equidistant spacing parallel to the axis of the arc-shaped clamping block 2, thereby supporting and reinforcing the arc-shaped clamping block 2.
