Embodiment 1

[0061] Such as figure 1 As shown in , a bending-resistant multi-strand steel wire rope 1 with a diameter of φ1 mm is degreased with acetone, and the high-temperature-resistant inorganic adhesive is applied to the steel wire rope at certain intervals. After drying and curing, an isolation masking area 2 is formed.

[0062] Take the metal brazing material, add organic glue and make a paste.

[0063] Such as figure 2 As shown in , use paste metal brazing material to smear the spaced part 3 on the multi-strand steel wire rope 1, then sprinkle diamond particles 4, spray a layer of paste metal brazing material after solidification, and then sprinkle diamond particles 4. Spray a layer of paste metal brazing material after solidification, put it into a vacuum brazing sintering furnace after drying, raise the temperature to 950°C, then cool it and take it out to obtain a semi-finished diamond wire saw. Such as image 3 with Figure 4 As shown in , the semi-finished wire saw is san...

Embodiment 2

[0066] Such as Image 6 As shown in , take a single thin steel wire 6 with a diameter of φ0.8mm, dip it in high temperature resistant inorganic glue and take it out. The release layer 7.

[0067] Take diamond abrasive grains and metal brazing material, add organic glue and make paste.

[0068] Such as Figure 7 As shown in , the release layer 7 is coated or cold-pressed with a diamond-containing paste 8 at intervals, and then the single-strand steel wire 6 coated with the paste 8 is put into a vacuum brazing furnace for sintering. After drying, place it in a vacuum brazing furnace and heat it up to 950°C before sintering. After cooling, exit the single-strand steel wire at the center to obtain a self-supporting (that is, without a metal matrix) ring-shaped diamond brazing layer (paste 8 obtained after sintering), that is, as Figure 8 The diamond bead 40 shown in. Then these beads 40 are strung on the φ1mm bending-resistant multi-strand steel wire rope 1 at intervals, and...

Embodiment 3

[0071] Take diamond abrasive grains and metal brazing material, add organic glue and make paste.

[0072] Take a steel pipe with a diameter of 0.5 mm to 2 mm, coat or cold press the paste on it, and then put it into a vacuum brazing furnace for sintering. After being released from the furnace, the above-mentioned steel pipe is cut into small sections with a length of 5-10 mm to obtain a diamond bead with a metal matrix 9, such as Figure 9 shown in . Then these beads 40 are strung on the φ1mm bending-resistant multi-strand steel wire rope 1 at intervals, and fixed with glue to obtain a semi-finished wire saw. Then coat a layer of polyurethane glue 5 on the space between the semi-finished products of the wire saw, and make such as Figure 4 The diamond wire saw shown in .

[0073] Such as Figure 4 with Figure 9 As shown in , a diamond wire saw includes a multi-strand steel wire rope 1 resistant to bending. The diameter of the steel wire rope 1 is 0.5-2.0 mm, and several ...

Abstract

The invention discloses a diamond wire saw and a preparation method thereof. The diamond wire saw comprises a bending-resistant flexible multi-strand rope. The preparation method comprises the following steps: a, removing oil from the surface of the flexible multi-strand rope and coating high-temperature resistant inorganic glue onto the flexible multi-strand rope at intervals, so as to form an isolated coating layer after the glue is cured; b, adding metal soldering materials into the organic glue to prepare a pastry mixture; c, coating or impregnating the pastry metal soldering materials onto the spaced parts of the flexible multi-strand rope, and then spreading diamond abrasive particles onto the rope; spraying or cold-pressing a layer of metal soldering materials onto the surface of the rope after the organic glue is cured; d, putting the obtained flexible multi-strand rope into a vacuum brazing furnace for sintering, taking the rope out of the furnace and then removing the inorganic glue; after heat treatment, coating a layer of rubber-plastic material protection layer onto the spaced parts of the flexible multi-strand rope; after the glue is cured, obtaining the diamond wire saw. The diamond wire saw can effectively prevent a braze-welding material from entering into gaps of the flexible multi-strand rope so as to solve the problem that the conventional diamond wire saw manufactured by taking the flexible multi-strand rope as a centre line is too inflexible and is entirely unusable.

Description

technical field [0001] The invention relates to a diamond tool and a preparation method thereof, in particular to a diamond wire saw and a preparation method thereof. Background technique [0002] As a widely used cutting tool, the diamond wire saw is mostly used for crystal cutting, and its diameter is mostly 0.1 to 0.45mm. The diamond wire saw used for crystal processing has a small diameter and a small kerf, which has the advantages of less material consumption and less waste. features. However, most of the existing diamond wire saws are obtained by directly depositing or brazing very fine diamond particles on the steel wire by means of electroplating or brazing, such as a "new diamond wire saw" disclosed in CN200710009082. "Wire saw", which is a wire saw made by brazing diamond on a single square, trapezoidal, and bow-shaped flat section; and as CN200420005349.6 also discloses "a diamond wire saw for cutting hard and brittle materials ", which is to attach fine-grained...
