Description

Technical Field

[0001] The utility model relates to the technical field of wire stranding machines, in particular to a high-speed cantilever wire stranding machine. Background Art

[0002] A wire stranding machine is a type of mechanical equipment widely used to twist various types of soft and hard conductors, twisting multiple individual conductors into a single strand to meet the wire's processing requirements. Wire stranding machines can be generally categorized by stranding method, including single stranding machines, pair stranding machines, back-twist machines, frame stranding machines, tubular stranding machines, and disc stranding machines.

[0003] After wrapping the multiple core wires of the twisted cable, the multiple cables are twisted together, and finally the cables are wound on the cable reel through the cable arrangement rotating arm. When twisting the multiple cores, the cores need to be dispersed by the anti-winding mechanism to avoid entanglement between the cores. When the cores are twisted, the cores are in a straight state, and the straightened cores contact the wire holes on the anti-winding mechanism. After the cores move and contact the wire holes, the inner wall of the wire hole scratches the core, causing scratches on the surface of the core, reducing the twisting effect of the core. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art that the straightened wire core contacts the wire hole on the anti-winding mechanism, the wire core contacts the wire hole after moving, the inner wall of the wire hole scrapes the wire core, scratches the surface of the wire core, and reduces the wire core twisting effect, and a high-speed cantilever stranding machine is proposed.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] Design a high-speed cantilever stranding machine, including a base plate, wherein:

[0007] The upper end of the base plate is fixedly connected to a support frame, the upper end of the support frame is fixedly connected to an anti-winding mechanism, the upper end of the support frame is fixedly connected to a wire closing frame, and the upper end of the base plate is fixedly connected to a cantilever stranding mechanism;

[0008] The anti-winding mechanism includes a vertical plate, which is fixedly connected to the upper end of the support frame. A plurality of wire holes are opened on the vertical plate, and a plurality of elastic extrusion parts are connected to each of the wire holes at equal intervals along the axis direction.

[0009] Preferably, a wire bucket is fixedly connected to the vertical plate.

[0010] Preferably, the elastic extrusion member includes an extrusion block, a groove is provided in the wire hole, the extrusion block is slidably connected to the groove, a spring is fixedly connected to the extrusion block, and one end of the spring is fixedly connected to the groove.

[0011] Preferably, a first baffle is fixedly connected to one side of the extrusion block, and a second baffle is fixedly connected to the other side of the extrusion block, and the first baffle and the second baffle are staggered.

[0012] Preferably, the extrusion block, the first baffle and the second baffle are an integrated structure.

[0013] The high-speed cantilever stranding machine proposed in this utility model has the following beneficial effects:

[0014] The combined wire cores are twisted by a cantilever twisting mechanism. When the cantilever twisting mechanism twists the wire cores, the wire cores are in a taut state. The taut wire cores squeeze the elastic extrusion parts, and the elastic extrusion parts elastically push the wire cores to avoid contact between the wire cores and the inner wall of the wire hole, reducing the scratching intensity on the surface of the wire cores, thereby improving the twisting effect of the wire cores.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Example 1

[0022] Reference Figure 1-3 , a high-speed cantilever stranding machine, comprising a bottom plate 1, wherein:

[0023] The upper end of the bottom plate 1 is fixedly connected to a support frame 2, the upper end of the support frame 2 is fixedly connected to an anti-winding mechanism 3, the upper end of the support frame 2 is fixedly connected to a wire closing frame 5, and the upper end of the bottom plate 1 is fixedly connected to a cantilever stranding mechanism 6;

[0024] The anti-winding mechanism 3 includes a vertical plate 31, which is fixedly connected to the upper end of the support frame 2. A wire bucket 4 is fixedly connected to the vertical plate 31. A plurality of wire holes 32 are opened on the vertical plate 31, and each wire hole 32 is connected to a plurality of elastic extrusion parts 33 at equal intervals along the axial direction.

[0025] Working process: the pay-off mechanism releases the wire core, and different wire cores pass through different wire holes 32. The wire guide bucket 4 guides and limits the wire cores entering the wire hole 32. The wire cores passing through different wire holes 32 pass through the wire combining frame 5. The wire combining frame 5 combines the wire cores. The combined wire cores enter the cantilever stranding mechanism 6. The cantilever stranding mechanism 6 strands the combined wire cores. When the cantilever stranding mechanism 6 strands the wire cores, the wire cores are in a taut state. The taut wire cores squeeze the elastic extrusion piece 33. The elastic extrusion piece 33 elastically pushes the wire core to avoid contact between the wire core and the inner wall of the wire hole 32, reduce the scratching strength on the surface of the wire core, and thus improve the stranding effect of the wire core.

[0026] Example 2

[0027] Reference Figure 4 As another preferred embodiment of the present invention, the difference from embodiment 1 is that the elastic extrusion member 33 includes an extrusion block 331, a groove 332 is formed in the wire hole 32, the extrusion block 331 is slidably connected to the groove 332, and a spring 333 is fixedly connected to the extrusion block 331, and one end of the spring 333 is fixedly connected to the groove 332;

[0028] The first baffle 34 is fixedly connected to one side of the extrusion block 331, and the second baffle 35 is fixedly connected to the other side of the extrusion block 331. The first baffle 34 and the second baffle 35 are staggered. The extrusion block 331, the first baffle 34 and the second baffle 35 are an integrated structure. The wire core squeezes the extrusion block 331, and the extrusion block 331 squeezes the spring 333. The spring 333 is compressed to generate elastic force. The elastic force generated by the spring 333 pushes the extrusion block 331. The extrusion block 331 pushes the wire core so that the wire core will not contact the inner wall of the wire hole 32. The first baffle 34 and the second baffle 35 between adjacent extrusion blocks 331 cooperate with each other. The first baffle 34 and the second baffle 35 block and seal the gap between adjacent extrusion blocks 331, so that the wire core will not fall into the gap between adjacent extrusion blocks 331, thereby improving the pushing effect on the wire core.

[0029] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
