AI Technical Summary
When producing 35W×7 type steel wire ropes, the number of pre-deforming rollers of the existing pre-deformers is insufficient, resulting in insufficient deformation of the rope strands, and the steel ropes are not tight after the rope is closed, which affects the service life.
The pre-deformer device with 4 discs is adopted to increase the number of deformation times the rope strand passes through the pre-deforming roller, and to ensure that the rope strand is fully deformed by adjusting the roller end distance and bending depth.
It improves the twisting quality of the wire rope, avoids early fatigue and breaks of wire, and extends the service life.

Abstract
Description
Technical Field
[0001] The present invention relates to a device for producing 35W×7 type steel wire ropes, belonging to the technical field of manufacturing and processing of metal products. Technical Background
[0002] When producing 35W×7 type steel wire ropes, ensuring the tight twisting is crucial for the quality of the steel ropes. If the steel wire ropes are not tightly twisted, early fatigue wire breaks are likely to occur during use, resulting in a reduced service life. When producing 35W×7 type steel wire ropes, the currently used pre-deformer only has 3 discs and there are only 3 pre-deformation rollers in the same axial section of the pre-deformer. After the wire strands pass through the pre-deformation rollers, they only undergo 1 deformation. Since the outermost strands of 35W×7 type steel wire ropes have a small diameter and are very flexible. During the rope closing process, the deformation is insufficient after passing through the pre-deformer, resulting in the phenomenon that the steel ropes are not tight after rope closing. Summary of the Invention
[0003] The problem to be solved by the present invention is that during the rope closing process, the wire strands are not sufficiently deformed after using the pre-deformer, resulting in the steel ropes not being tight after rope closing.
[0004] To solve the above technical problems, the present invention adopts the following technical solutions: A device for producing 35W×7 type steel wire ropes, which is composed of a cylinder body, an A adjusting sleeve, an A worm gear, a hollow main shaft, an A adjusting nut, a B adjusting sleeve, a B worm gear, a B adjusting nut, a C adjusting nut, pre-deformation rollers, a worm, a D disc, a C disc, a B disc and an A disc; The A disc, B disc, C disc and D disc are respectively installed on the hollow main shaft, A adjusting nut, C adjusting nut and B adjusting nut; The A adjusting sleeve and B adjusting sleeve are respectively connected to the A adjusting nut and B adjusting nut through splines to adjust the end distance of the rollers; The A worm gear and B worm gear are respectively installed on the A adjusting nut and B adjusting nut; The A worm gear and B worm gear are respectively connected to the worm to adjust the bending depth; The A adjusting nut, B adjusting nut and C adjusting nut are connected through trapezoidal threads.
[0005] The beneficial effects of adopting the above technical solutions are: The present invention effectively solves the problem that during the rope closing process, the wire strands are not sufficiently deformed after using the pre-deformer, resulting in the steel ropes not being tight after rope closing.

Specific implementation manner
[0010] The present invention will be further described in detail below with reference to the accompanying drawings: Those skilled in the art provided a pre-deformer device with 4 disks. In the same axial section of the pre-deformer, there are 4 pre-deformation rollers. After the wire strand passes through the pre-deformation rollers, there are 2 deformations, making the wire strand deformation more sufficient and improving the quality of wire rope stranding.
[0011] The technical solution adopted is: changing the pre-deformer with 3 disks to a pre-deformer with 4 disks, and increasing the number of deformations of the wire strand from 1 time to 2 times after passing through the pre-deformation rollers.

[0013] A device for producing 35W×7 type wire ropes includes the following implementation steps: a. When producing wire ropes, place the wire strand according to Figure 2As shown, it passes through the pre-deformation roller 10, and then rotates the A adjusting sleeve 2. The B disk 14 and the C disk 13 move axially backward. When the distance between the pre-deformation roller 10 on the A disk 15 and the pre-deformation roller 10 on the C disk 13 is equal to 0.83 times the twist pitch, stop rotating the A adjusting sleeve 2, and then close the A adjusting sleeve 2 and the A adjusting nut 5; b. Rotate the B adjusting sleeve 6, and the D disk 12 moves axially backward. When the distance between the pre-deformation roller 10 on the B disk 14 and the pre-deformation roller 10 on the D disk 12 is equal to 0.83 times the twist pitch, stop rotating the B adjusting sleeve 6, and then close the B adjusting sleeve 6 and the C adjusting nut 9; c. Rotate the worm 11, driving the pre-deformation roller 10 arranged on the B disk to rotate circumferentially axially, driving the pre-deformation roller 10 arranged on the D disk to rotate circumferentially axially, so that the bending depth of the pre-deformer meets the process requirements.
