A wire rope consists of steel wires, a rope core, and grease. First, multiple layers of steel wires are stranded into strands, and then, with the rope core as the center, a certain number of strand steel wires are stranded into a helical rope body by a stranding machine according to a certain lay length and lay direction. It is used for lifting, traction, tensioning, and load-bearing in material handling devices. In the actual production process, according to the usage requirements, a galvanized layer, zinc-aluminum alloy layer, aluminum-clad layer, copper-plated layer, epoxy resin layer, etc. can be added to the surface of carbon steel.

[0041] Referring to Figure 4 , a circulation cavity is formed between the inner box 2 and the processing box 1, and a circulation pump 13 for facilitating the air circulation in the inner box 2 is arranged in the circulation cavity. An intake manifold 14 and an air delivery manifold 15 are also connected to the circulation pump 13.

One ends of the plurality of intake branch pipes 16 and the plurality of air delivery branch pipes 17 are fixedly connected to the inner box 2 and communicated with the inner cavity of the inner box 2.

[0042] Referring to the figure, when stress relieving the wire rope, the wire rope enters the inner box 2 through the wire inlet 101 of the processing box 1, and the wire rope successively passes through a plurality of first abutting rollers 38 on the connecting vertical plate 31 and abuts against them. For wire ropes of different thicknesses and materials, their internal stress magnitudes are different, and the positions of the first abutting rollers 38 need to be adjusted according to specific requirements. The driving motor 37 is started to drive the abutting eccentric wheel 36 to rotate. Under its driving action, the mounting plate 32 in contact with the abutting eccentric wheel 36 is adjusted along the length direction of the sliding groove 311, realizing the adjustment of the distance between the two rows of first abutting rollers 38. The provision of the first scale line 9 facilitates the operator to accurately adjust the position of the mounting plate 32. At the same time, the distance between the first abutting rollers 38 in the same row also needs to be adjusted according to actual needs. By screwing the corresponding adjusting screw 8, the adjusting block 7 slides in the adjusting groove 321 under the action of the adjusting screw 8. The provision of the second scale line 10 facilitates the operator to accurately adjust the distance between adjacent first abutting rollers 38.

[0043] Referring to Figures 2-4 , the wire rope passing through the first stress relief assembly 3 extends above the connecting cross plate 41, and the wire rope successively passes through a plurality of second abutting rollers 44 and abuts against them. Combining Figure 5 , different numbers of second abutting rollers 44 can be installed at appropriate positions on the connecting cross plate 41 according to different stress relief requirements. The driving cylinder 42 drives the connecting cross plate 41 to move in the vertical direction so that the position of the connecting cross plate 41 corresponds to the height position of the wire rope. The wire rope stretched by the first stress relief assembly 3 and the second stress relief assembly 4 realizes the elimination of its internal stress. Since the positions of the first abutting rollers 38 and the second abutting rollers 44 can be adjusted, the device can process wire ropes of different specifications, expanding the application range of the device.

[0044] Referring to Figure 2 and Figure 4 , the wire rope passing through the second stress relief assembly 4 successively bypasses a plurality of guide rollers 12. The wire rope approaches the heating plate 51 and the heating coil 52 under the guidance of the guide rollers 12. The heating plate 51 and the heating coil 52 generate heat, and the wire rope is heated to change its physical properties, so that the stress inside the wire is released. The provision of the heating assembly 5 further improves the effect of eliminating the internal stress of the wire rope. In addition, the provision of the guide rollers 12 prolongs the residence time of the wire rope in the processing box 1, which helps to improve the stress relief effect of the wire rope. The processed wire rope extends out of the processing box 1 through the wire outlet 102, and the provision of the guide ring 103 reduces the possibility of friction damage when the wire rope enters and exits the processing box 1.

[0045] Referring to Figure 4, while the wire rope is being processed, the circulation pump 13 is started, and the gas in the inner box 2 enters the circulation pump 13 through the intake branch pipe 16 and the intake manifold 14, and then flows back into the inner box 2 again through the gas delivery manifold 15 and the gas delivery branch pipe 17. The setting of the circulation pump 13 improves the circulation degree of the gas in the inner box 2, which helps to improve the temperature uniformity of each part in the inner box 2 and improve the stress relief effect of the heat treatment of the wire rope.

[0046] The implementation principle of a stranding machine for eliminating the rebound stress of a wire rope in an embodiment of the present application is as follows: when stress relieving the wire rope, the wire rope sequentially passes through a number of first abutting roller wheels 38 and abuts against them. The driving motor 37 adjusts the distance between the two rows of first abutting roller wheels 38. At the same time, the corresponding adjusting screw 8 is rotated to adjust the distance between adjacent first abutting roller wheels 38. The wire rope passing through the first stress relief assembly 3 sequentially passes through a number of second abutting roller wheels 44 and abuts against them. The wire rope stretched by the first stress relief assembly 3 and the second stress relief assembly 4 realizes the elimination of its internal stress.

[0047] The wire rope passing through the second stress relief assembly 4 successively bypasses a number of guide rollers 12, and the wire rope approaches the heating plate 51 and the heating coil 52. The wire rope is heated to change its physical properties, so that the stress inside the wire is released.

[0048] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
