Problems solved by technology

The rope made of twisted steel wire with round cross-section, there is a gap between the steel wire and the steel wire, which will seal the acid and alkali or the plating solution during the electroplating process, causing the core steel wire to gradually corrode. If it cannot be removed, the breaking force of the electroplated diamond rope will be reduced , In addition, during the use of the diamond rope, it is repeatedly bent under high tension, and the corrosion pits or spots on the inner surface will reduce the fatigue strength and affect the cutting effect

Embodiment approach 1

[0028] (1) Core rope production: The core rope is made of 3 strands of φ0.08mm high-strength steel wire;

[0029] (2) Surface pretreatment: The above-mentioned core ropes are released through the pay-off wheel, and then go through the alkaline degreasing agent solution at 60±5°C, washing water, 10% sulfuric acid solution at 40±5°C and washing water respectively. Dry at 110±5°C to obtain a core rope with a clean surface;

[0030] (3) Core rope plating bottom coating: brass bottom coating is plated on the outer surface of the core rope;

[0031] (4) Resin slurry coating: uniformly coat the phenolic resin slurry with diamond powder with a particle size of 20 μm on the surface of the core rope to obtain a resin diamond wire, wherein the method of coating the core rope is to install the core rope on On the wire feeding shaft, the core rope passes through the mold and runs continuously at a speed of 0.5m / s-1m / s;

[0032] (5) Initial curing of the resin diamond wire: the resin diam...

Embodiment approach 2

[0035] The difference from Example 1 is that the core rope in the step (1) of making the core rope is a core rope made by twisting three φ0.09mm steel wires. Step (2) surface pretreatment adopts 100-200g / l mixed acid to carry out pickling, described mixed acid comprises sulfuric acid 30%, oxalic acid 10%, hydrochloric acid 15%, phosphoric acid 10%, thiourea 0.5%, benzotriazepine azole 0.5%, the rest is water. Step (4) The diameter of the diamond micropowder particles in the resin slurry coating is 30 μm, and the steps (5) and (6) are the same as in Embodiment 1.

Embodiment approach 3

[0037] The difference from Embodiment 1 is that the surface pretreatment in step (2) uses 100-200g / l mixed acid for pickling, and the mixed acid includes 30% sulfuric acid, 10% oxalic acid, 15% hydrochloric acid, and 10% phosphoric acid. %, 0.5% thiourea, 0.5% benzotriazole, and the rest is water. Step (4) In the resin slurry coating, the line speed is 1.0m / s-1.5m / s, and the resin used is a mixture of phenolic resin and epoxy resin in a mass ratio of 4:1. Step (5) In the initial curing of the resin diamond rope, the temperature is 600±50° C. and the initial curing is rapid for 20 seconds. Step (6) During the curing of the resin diamond rope, the temperature is raised to 200° C. within 8 hours, isothermally raised every hour, kept for another 5 hours, and then naturally lowered to room temperature.

[0038] Of course, the resin slurry of the present invention can also be made of polyimide resin or its mixture with phenolic resin and epoxy resin.

Abstract

The invention relates to the technical field of diamond wires, in particular to a resin consolidated abrasive diamond wire. The resin consolidated abrasive diamond wire comprises a core wire formed by twisting a plurality of steel wire strands, a brass bottom plated layer is plated on the outer side of the core wire, a consolidated resin layer is cured at the outer side of the brass bottom plated layer, and diamond micro-powder granules are distributed in the consolidated resin layer. The invention also discloses a resin consolidated abrasive diamond wire production process. The production process comprises the following steps: manufacture of the core wire; surface pretreatment; plating of the core wire bottom plated layer; resin paste coating; and resin diamond wire curing. Compared with an electroplated diamond wire, the resin diamond wire produced by the process has the advantages that corrosion caused by a solution accumulated in the space of a wire core part can be avoided due to no contact with a water-phase electrolyte solution during production of the resin combined diamond wire. Compared with a metal combination layer of the electroplated wire, the resin layer is low in rigidity, so that the thickness of an effected layer of a cut surface of a processed workpiece is lower than that of the electroplated wire, and the stress of a section is small. Resin coating and curing can be finished in two stages, thereby realizing high-speed production and reducing production cost greatly.

Description

technical field [0001] The invention relates to the technical field of diamond ropes, in particular to a resin-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 depression formed naturally on the surface of the rope is conducive to chip removal and improves cutting efficiency. The rope made of twisted steel wire with round cross-section, there is a gap between the steel wire and the steel wire, which will seal the acid-base or plating solution during the electroplating process, causing the core steel wire to gradually corrode. If it cannot be removed, the breaking force of the electroplated diamo...
