Steel wire rope for reinforcing belt framework and production equipment and technology thereof

Abstract

The invention relates to a steel wire rope for reinforcing a belt framework and production equipment and technology thereof. The steel wire rope has ultrahigh strength and high accuracy; the steel wire rope has good integrity and good combination with polyurethane belts and cannot be layered; the steel wire rope can prevent a zinc layer from contacting water and can prevent secondary oxidation pollution; steel wire rebound stress can be eliminated, so that quality of steel wires is improved; furthermore, the length of the steel wire rope is super long, and tensile strength at the connector position can meet a steel wire rope quality standard requirement; the steel wires cannot deviate when being drawn by a deformation cone of a wire drawing mold, and stress is prevented from being generated; thus, accuracy of the steel wires is improved, and quality is improved; when the steel wires are combined into a rope, internal stress twisting to the center is generated in advance, so that the steel wire rope is not prone to loosening, and the rope diameter can be more accurate; a wire release assembly can adjust a wire releasing speed by self elasticity of a spring, so that wire releasing tension can be stabilized, and the steel wires can be evenly stressed in a wire releasing process; as the single wire is evenly stressed, drawn in a high compression mode and tight twisting are realized, the manufactured steel wire rope has the advantages of low elongation and higher quality.

Description

technical field [0001] The invention relates to a steel wire rope for reinforcing a belt skeleton and its production equipment and process, belonging to the technical field of steel wire ropes. Background technique [0002] Steel wire ropes for belt frame reinforcement have requirements such as high strength, low elongation, extra length, high precision and uniform force. However, the previous steel wire ropes have the following defects: [0003] 1. The strength of the wire rope is not high and the quality is poor. [0004] 2. When the steel wire rope is galvanized, it needs to pass through the electroplating tank back and forth, but the super long steel wire rope needs a longer electroplating tank during electroplating, and the space of the factory building is limited. In addition, the longer electroplating tank has a higher current during electroplating. High current galvanizing will result in less precision wire ropes. [0005] 3. Most of the steel wire ropes are 7*3 or...

AI Technical Summary

Problems solved by technology

[0003] 1. The strength of the wire rope is not high and the quality is poor

[0004] 2. When the steel wire rope is galvanized, it needs to pass through the electroplating tank back and forth, but the super long steel wire rope needs a longer electroplating tank during electroplating, and the space of the factory building is limited. In addition, the longer electroplating tank has a higher current during electroplating. High current galvanizing will lead to low precision of wire rope

[0005] 3. Most of the steel wire ropes are 7*3 or 7*7 structures, which have poor integrity, poor combination with polyurethane, and easy delamination

[0006] 4. The steel wire rope is easy to make the zinc layer contact with water during ultrasonic cleaning, resulting in secondary oxidation pollution; when the glue in the glue tank in the gluing device overflows, it is easy to fall out of the device, resulting in waste of glue

[0007] 5. After the steel wire rope is closed, there is still a certain rebound stress in a single steel wire, which affects the quality of the steel wire

[0008] 6. When welding steel wire, because the single steel wire is relatively thin, it is easy to break the wire when welding with a single steel wire

[0009] 7. When the steel wire is finely drawn, the steel wire cannot be guaranteed to be parallel to the central axis of the wire drawing die when it travels, causing the steel wire to easily deviate when drawn through the deformation cone of the wire drawing die, thereby generating stress, reducing the accuracy of the steel wire, and affecting its quality.

[0010] 8. After the conventional steel wire rope is closed, the steel wire is easy to loose

[0011] 9. When the steel wire rope is twisted and closed, the pay-off speed of the pay-off device is unstable, so that the steel wire cannot be uniformly stressed during the pay-off process, which affects the quality of the steel wire

[0012] 10. The elongation rate of the conventional steel wire rope is not low, which affects the service life of the steel wire rope for belt skeleton reinforcement
