Embodiment approach 1

[0038] (1) Core rope composite: The core rope is prepared by twisting three strands of φ0.080mm copper-plated steel wire and one strand of φ0.010mm soft polymer filling strip. The material of the soft polymer filling strip is ethylene-ethyl acrylate copolymer Material, its ethyl acrylate content is 20-30%.

[0039] (2) Surface pretreatment: 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 with a clean surface. rope.

[0040] (3) Adhesive nickel layer deposition: The core rope that has been cleaned on the surface is deposited on the surface with a layer of nickel layer medium with high adhesion and fine grains through the flash nickel process. By adjusting the speed of the metal rope, solution formula, current, and pH value , temperature, stirring and other parameters to adjust the grain size and film thickness distribution of t...

Embodiment approach 2

[0045] The difference from Example 1 is that the core rope is a core rope made by twisting three strands of φ0.130mm copper-plated steel wire and one strand of φ0.017mm soft polymer filling strip, and the material of the soft polymer filling strip is Ethylene-propylene-1-butene copolymer, the specification of the diamond particles is 30 / 40. Other steps are all the same as in Example 1, and the specification of the finished product diamond rope is 0.340±0.015mm.

Embodiment approach 3

[0047]The difference from Example 1 is that the core rope is a core rope made by twisting three strands of φ0.160mm copper-plated steel wire and one strand of φ0.020mm soft polymer filling strip, and the material of the soft polymer filling strip is Ethylene-propylene-1-butene copolymer, the specification of the diamond particles is 40 / 50. Other steps are all the same as in Example 1, and the specification of the finished product diamond rope is 0.420±0.020mm.

[0048] The material of the polymer fiber silk in the present invention can be polyethylene, polyvinyl acetate, polyethyl acrylate, polypropylene, polyamide, linear saturated polyester, polyurethane and other thermoplastic polymers, and can also be the above-mentioned polymers The copolymer has a softening point between 50-150°C.

Abstract

The invention relates to the technical field of diamond ropes, in particular to a novel composite metal fixed abrasive diamond rope. The novel composite metal fixed abrasive diamond rope comprises a core rope which is prepared by twisting a plurality of copper-plated steel wires and a soft polymer filling strip, wherein an attaching nickel layer for attaching diamond particles is deposited at the outer side of the core rope; the diamond particles are deposited on the attaching nickel layer on the surface of the core rope; and a packaging nickel layer for covering the diamond particles is deposited on the surfaces of the diamond particles. The invention further discloses a production process for the novel composite metal fixed abrasive diamond rope, wherein the production process comprises the following steps: compounding the core rope; carrying out surface pre-treatment; depositing the attaching nickel layer; attaching diamond; and depositing the packaging nickel layer. After the process is adopted, the core part of the core rope is free of a remarkable gap, so that a water-phase electrolyte solution is not remained in the space of the rope core, and therefore, corrosion is avoided; after the rope core is filled with soft stuffing, the diamond rope fracture risk is reduced; besides, by virtue of a buffer layer, slippage among steel wires is restricted, and coating is integrated, so that the coating fracture risk is reduced, and therefore, the line breakage risk in use is further reduced.

Description

technical field [0001] The invention relates to the technical field of wire cutting, in particular to a novel composite metal-bonded abrasive diamond wire 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. There is a hollow in the center of the rope made of round-section steel wire, which will seal the acid-base or plating solution during the electroplating process, causing the core steel wire to corrode gradually, thereby reducing the break...
