[0002] The purpose of pre-deformation is to use certain methods to make the steel wire deform in a way that fits the steel strand before it is twisted into a strand, so that the steel wire does not become loose after it is twisted into a rope.

[0003] Our company has developed a steel wire rope with the model number 6 / 6-6-1. The model number is explained as follows: 6 (number of outer thin strands) / 6 (number of outer thick strands) - 6 (number of inner thick strands) - 1 (number of core strands). The structural composition of the outer thin strands D, outer thick strands C, inner thick strands B, and core A is as follows (refer to...). Figure 11 As shown, the rope core A is located at the center, and six inner thick rope strands B are arranged around the outer periphery of the rope core A. Between each two inner thick rope strands B, an outer thick rope strand C is arranged, and between each two outer thick rope strands C, an outer thin rope strand D is arranged.

[0056] Please see Figure 2The side deformation plate 2 includes a first disc body 21, which is mounted on the main shaft 1. Six first slots 21a and six second slots 21b are respectively provided along the circumference of the first disc body 21. The first slots 21a and the second slots 21b are arranged at intervals.

[0057] The number of the first slot 21a and the second slot 21b corresponds to the new products of this company, and is not limited to a maximum of 6.

[0058] Six second winding rollers 23 and six third winding rollers 24 are arranged one-to-one in the first slot 21a, with the second winding rollers 23 arranged on the outer side;

[0059] Six first winding rollers 22 are arranged one-to-one in the second slot 21b;

[0060] Please see Figure 3 and Figure 4 The deformable plate 3 includes a second disc 31, which is mounted on the main shaft 1. Six third slots 31a and six fourth slots 31b are respectively provided along the circumference of the second disc 31. The third slots 31a and the fourth slots 31b are spaced apart.

[0061] Six fifth winding rollers 33 and six sixth winding rollers 34 are arranged one-to-one in the third slot 31a, with the fifth winding rollers 33 arranged on the outer side;

[0062] Six additional fourth winding rollers 32 are arranged one-to-one in the fourth slot 31b;

[0063] It also includes 12 pressing amount adjustment devices 35 for adjusting the pressing amount of the fifth winding roller 33, the sixth winding roller 34 and the fourth winding roller 32.

[0064] When using, pass the 6 outer thin rope strands D, 6 outer thick rope strands C, and 6 inner thick rope strands B through the splitter 4 from back to front, and then pass them through the side deformation piece 2 on the back side, the middle deformation piece 3 and the side deformation piece 2 on the front side in sequence as required.

[0065] Reference for wiring requirements Figure 8 and Figure 9 The inner coarse rope strand B passes sequentially through the upper edge of the third winding roller 24 on the rear side, the lower edge of the sixth winding roller 34, and the upper edge of the third winding roller 24 on the front side.

[0066] The outer layer of fine rope strand D passes sequentially through the upper edge of the second winding roller 23 on the rear side, the lower edge of the fifth winding roller 33, and the upper edge of the second winding roller 23 on the front side.

[0067] The outer thick rope strand C passes sequentially through the upper edge of the first winding roller 22 on the rear side, the lower edge of the fourth winding roller 32, and the upper edge of the first winding roller 22 on the front side.

[0068] Rope core A passes through the center hole 1a from behind to the front;

[0069] Then the pre-deformer rotates to achieve twisting, which makes the product tight and non-loose after twisting, thus improving the product's service life.

[0070] Please see Figure 5 In order to improve the service life of the through hole 4a of the distributor plate 4, a wear-resistant bushing made of ceramic material is provided in the through hole 4a, which is not shown in the figure.

[0071] Please see Figures 5 to 7 This is an embodiment of a press-in amount adjustment device 5, which includes a slider 355 in the third slot 31a or the fourth slot 31b. The slider 355 slides back and forth along the diameter direction of the second disc 31, and the slider 355 has a receiving window 355a that extends through the front and back.

[0072] The fourth winding roller 32, the fifth winding roller 33 and the sixth winding roller 34 are respectively arranged in the receiving window 355a. As can be seen in the figure, the height of the receiving window 355a corresponding to the fourth winding roller 32 is shorter, while the height of the receiving window 355a corresponding to the fifth winding roller 33 and the sixth winding roller 34 is longer. The structure is the same, the difference is the length.

[0073] The top of the slider 355 is connected to the bottom of the screw of the adjusting bolt 354;

[0074] The two sides of each of the 12 pressure plates 351 are connected to the openings at the top of the third slot 31a and the fourth slot 31b respectively by connecting screws 352.

[0076] The adjusting bolt 354 includes a top head that extends outward from the pressure plate 351.

[0077] In use, rotating the head of the adjusting bolt 354 will drive the slider 355 downwards, thereby adjusting the amount of pressure applied. (See reference...) Figure 8 and Figure 10 This is the state after pressing and adjustment, which makes the twisting effect of the wire rope better.

[0078] To prevent the adjusting bolt 354 from loosening, the bolt of the adjusting bolt 354 is also provided with a locking nut 353. The bottom of the locking nut 353 is in contact with the top of the pressure plate 351. If a better loosening effect is desired, a locking nut 353 that is in contact with the bottom of the pressure plate 351 can also be provided at the bottom of the pressure plate 351, which is not shown in the figure.

[0079] To improve sliding performance and prevent wobbling during sliding, the slider 355 has a groove 355b extending along the sliding direction on each of its left and right sides. The front and rear sides of the second plate 31 slide in cooperation with the front and rear sidewalls of the groove 355b, so that the slider 355 can only slide up and down along the front and rear sides of the second plate 31, thereby improving sliding accuracy.

[0080] To improve stability, a retaining ring 6 is fitted on the front side of the side deformable piece 2, the middle deformable piece 3, and the dividing plate 4. The front sides of the side deformable piece 2, the middle deformable piece 3, and the dividing plate 4 are respectively attached to the rear surface of the corresponding retaining ring 6. The retaining ring 6 is provided to improve the resistance of the dividing plate 4, the middle deformable piece 3, and the side deformable piece 2 to frontal tension.

[0081] The side deformation plate 2, the middle deformation plate 3, the dividing plate 4, and the retaining ring 6 are all provided with internal threaded holes that connect to the external threads on the outer shaft surface of the main shaft 1, so as to facilitate disassembly and assembly and facilitate later maintenance.
