Embodiment approach 1

[0044] (1) Composite rope: the core rope is prepared by twisting 3 strands of φ0.080mm high-strength cutting steel wire, and the lay length of the rope is 5mm;

[0045] (2) Insulation filling: Heat and melt No. 60 industrial paraffin and keep it warm at 100°C, and pass the core rope through it;

[0046] (3) Surface pre-treatment: use a rotating brush wheel to scrub the wax-soaked core rope, and scrape off the paraffin wax at the raised position of the edge;

[0047] (4) Surface cleaning: the core rope is unwound by the pay-off wheel, and is treated with alkaline degreasing agent solution at 60±5°C, washing water, 10% sulfuric acid solution at 40±5°C and washing water to obtain a core rope with a clean surface ;

[0048] (5) Surface pretreatment: the core rope whose surface has been cleaned is deposited on the surface with a layer of nickel layer medium with high adhesion and fine grains through the flash nickel plating process;

[0049] (6) Diamond attachment: the diamond pa...

Embodiment approach 2

[0056] The difference from Embodiment 1 is that the core rope is made of 3 strands of φ0.130 steel wire, the insulating layer used is ethylene-ethyl acrylate copolymer resin with 23% ethyl acrylate content, and the specification of the diamond particles is 30 / 40. The other steps are the same as in the first embodiment, and the finished diamond rope has a specification of 0.340±0.015mm.

Embodiment approach 3

[0058] The difference from Embodiment 2 is that the core rope is made of 3 strands of φ0.160 steel wire, the insulating layer is polyacrylate resin, and the surface pretreatment process uses a sharpening machine to scrape with a green silicon carbide oilstone to remove the protrusions Part insulation layer, the process of removing the insulation layer uses dichloroethane solvent leaching and stripping, and the specification of the diamond particles is 40 / 50. The other steps are the same as in the first embodiment, and the finished diamond rope has a specification of 0.420±0.020mm.

Abstract

The invention relates to the technical field of diamond ropes, in particular to an improved composite metal-bonded abrasive diamond rope, which includes a core rope made of twisted strands of copper-plated steel wire and a strand of soft polymer filling strip, the core rope A nickel layer attached to the diamond particles is deposited on the outside, diamond particles are deposited on the nickel layer attached to the surface of the core rope; a nickel layer covering the diamond particles is deposited on the surface of the diamond particles. After adopting the above structure and method, compared with the ordinary electroplated diamond rope, the present invention has no obvious gap in the core of the diamond rope, and will not leave an aqueous phase electrolyte solution in the space of the rope core to avoid corrosion; the rope core is filled with paraffin wax or resin After the soft filler, there is a certain buffer layer between the steel wires, which reduces the friction between the steel wires during repeated bending at high tension during use, thereby reducing the risk of fatigue fracture of the diamond rope.

Description

technical field [0001] The invention relates to the technical field of diamond ropes, in particular to an improved composite metal-bonded abrasive diamond rope and a production process thereof. Background technique [0002] The current diamond rope is mainly made of circular cross-section steel wire twisted into a rope and then electroplated with diamond powder. Compared with the diamond wire directly plated with diamond powder by circular cross-section steel wire, it has many advantages. For example, when cutting (sapphire, crystal silicon), due to The spiral depressions naturally formed on the surface of the rope are very conducive to chip removal and improve cutting efficiency. [0003] There are following problems in prior art: [0004] 1. The rope made of twisted round-section steel wire has a hollow in the center. During the electroplating process, the acid-base or plating solution will be closed, causing the core steel wire to corrode gradually, thereby reducing the ...
