Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of surface opening of electroplated diamond wire saw, and particularly relates to a surface opening process of wire saw. BACKGROUND

[0002] In recent years, diamond wire has been increasingly popular, and the demand for diamond wire has been increasing year by year. The demand for diamond wire saw has also increased explosively, and the competition in the domestic market is extremely fierce. The cutting force and cutting quality of diamond wire are also increasing, and further improving the cutting efficiency and quality of diamond wire to ensure market competitive advantage is a work to be solved urgently. The diamond wire saw on the market is usually made of diamond abrasive by electrochemical deposition method to consolidate on the surface of steel wire, and is applied to cut brittle and hard non-metallic materials such as silicon wafer, sapphire and magnetic material.

[0003] The diamond plated on the market is consolidated on the surface of steel wire under the action of electric field. This process needs to be plated with nickel for multiple times to ensure the bonding force between diamond and steel wire. However, in this process, the originally sharp diamond is wrapped in the nickel layer, and the wrapped diamond may exist in a stacked form, which affects the cutting force and cutting quality. Therefore, after electroplating of diamond wire, the top nickel layer of wire saw surface diamond needs to be treated (also known as wire saw opening), so that the wire saw surface diamond is exposed as soon as possible, and the stacked diamond is subjected to secondary shaping treatment. The wire saw surface diamond nickel layer treatment method commonly used at present is to grind the wire saw by using oilstone after winding the wire saw on the guide wheel. This method has the following problems:

[0004] This method can easily cause nickel cutting and the accumulation of diamond particles falling off in the oilstone gap during the opening process. The nickel and diamond particles accumulated in the oilstone gap will cause surface scratches, nickel layer falling off and even wire breakage when they come into hard contact with the wire saw.

[0005] In the treatment process of this method, the wire saw needs to be wound evenly on the guide wheel. With the wear of the guide wheel, the wire saw may be stuck or combined, which can easily cause damage to the wire saw, and even directly cause wire breakage.

[0006] In the opening grinding process of this method, the contact surface between the wire saw and the oilstone is half-face hard contact, which can easily cause uneven grinding and uneven opening. In severe cases, it can cause half-face grinding damage and negative impact on the quality of steel wire.

[0007] In the actual operation process of this method, the wire saw wound on the guide wheel and the oilstone contact position will produce different wire bow due to uneven stress. When the wire bow difference is too large, it can easily cause cutting deviation and uneven grinding. In severe cases, it can cause wire breakage. SUMMARY

[0008] In view of the problems of the above background art, such as the surface damage of the wire saw, the peeling of the nickel layer, the uneven blade opening in the circumferential direction, and the problems of the wire connection and the wire breakage, the present application provides a wire saw surface blade opening process, which can effectively reduce the secondary damage of the wire saw surface and the wire breakage loss, and plays a role in quality protection, efficiency increase and cost reduction.

[0009] To this end, the present application adopts the following technical scheme: a wire saw surface blade opening process, comprising the following steps:

[0010] Firstly, a single wire saw is passed from the center of the rolling rotating cylinder body;

[0011] Secondly, the rolling cylinder body is filled with spherical abrasive and polygonal abrasive of a specified size;

[0012] Thirdly, the wire saw runs evenly in the cylinder body, and the rolling cylinder body drives the filled abrasive to roll around the wire saw passing through the center;

[0013] Fourthly, the abrasive rolls in the cylinder body and uniformly contacts the wire saw, and the friction generated by the contact preferentially grinds the nickel layer on the top of the diamond particles on the surface of the wire saw, thereby realizing the blade opening treatment and shaping of the surface of the wire saw.

[0014] As a supplement and improvement to the above technical scheme, the present application further includes the following technical features.

[0015] The specific operation steps of the first step are as follows: the wire saw is pulled out from the pay-off end carrier, passes through the wire guide roller in the wire running direction, passes through the center of the rolling cylinder body, and then passes out of the wire saw through the wire guide roller and is fixed to the take-up end carrier.

[0016] The specific operation steps in the second step are as follows: the spherical abrasive and the triangular abrasive are uniformly mixed by opening the rolling cylinder body door, and then poured into the rolling cylinder body to fill 2 / 3 of the volume of the rolling cylinder body cavity.

[0017] In the second step, the spherical abrasive used for the 0.34 specification wire saw has a diameter of 5mm, the polygonal abrasive has a size of 8*8mm triangular abrasive; the spherical abrasive used for the 0.45 specification wire saw has a diameter of 7mm, the polygonal abrasive has a size of 10*10mm triangular abrasive; the spherical abrasive used for the 0.25 specification wire saw has a diameter of 3mm, the polygonal abrasive has a size of 5*5mm triangular abrasive.

[0018] In the third step, the cylinder body rotation speed of the 0.34 specification wire saw is set to 100r / min, the cylinder body rotation speed of the 0.45 specification wire saw is set to 120r / min, and the cylinder body rotation speed of the 0.25 specification wire saw is set to 80r / min; the cylinder body and the abrasive are driven to roll by the power motor through the transmission gear belt.

[0019] In the third step, the wire saw running speed is 240 m / min, the wire saw is driven to move in the cylinder by the rotation of the take-up end carrier.

[0020] The present application has the following advantages: 1. The wire saw in the sharpening treatment process is covered with rolling abrasive in the circumferential direction, the surface top nickel layer has high removal efficiency, and the circumferential direction sharpening is more uniform. The wire saw in the sharpening treatment process of the present application is in elastic contact with the abrasive, not in the existing oil stone sharpening hard contact cutting mode, so there is no nickel cutting, diamond shedding and poor cutting, and the wire saw surface is not easy to be damaged and broken. The wire saw in the sharpening treatment process of the present application is single and runs in one direction, so there is no parallel line, line bow difference, and wire jamming, which can effectively reduce the occurrence of wire breaking. 2. The wire saw running speed and the drum rolling speed can be controlled and adjusted, and the parameterized control is beneficial to the adjustment of the surface sharpening intensity requirement, which improves the efficiency of the wire saw sharpening process.

[0024] As shown in Figure 1 Example 1, the surface sharpening treatment of 0.34 specification wire saw is carried out, and the operation and use process is as follows:

[0025] (1) The wire saw is pulled out from the take-up end carrier, passes through the wire guide along the running direction, passes through the center of the rolling cylinder, and passes through the wire guide to exit the wire saw, and is fixed to the take-up end carrier;

[0026] (2) Open the rolling cylinder closure door, uniformly mix 5mm diameter spherical abrasive and 8*8mm inclined triangular abrasive, and pour into the rolling cylinder, filling about 2 / 3 of the volume of the cavity;

[0027] (3) Start the rolling cylinder power motor, drive the cylinder and abrasive to roll through the transmission gear belt, and set the cylinder speed to 100 r / min;

[0028] (4) Start the take-up carrier rotation to drive the wire saw to move in the cylinder, and set the wire running speed to 240 m / min;

[0029] (5) After 2KM of the blade opening treatment, the re-measured line saw surface treatment blade missing and line saw diameter change are checked whether they meet the process requirements, and the cylinder speed is adjusted according to the re-measured results.

[0030] (6) After the blade opening treatment, the post-blade line saw is sampled and analyzed.

[0031] Example 2: Different from example 1, the surface blade opening treatment is performed on the 0.45 specification line saw, the grinding ball diameter is 7mm and the 10*10mm inclined triangular abrasive is used, and the cylinder speed is 120r / min. The other steps are the same as example 1.

[0032] Example 3: Different from example 1, the surface blade opening treatment is performed on the 0.25 specification line saw, the grinding ball diameter is 3mm and the 5*5mm inclined triangular abrasive is used, and the cylinder speed is 80r / min. The other steps are the same as example 1.

[0033] The line saw and the abrasive in the blade opening treatment process of the present application are in elastic contact, not in the existing oil stone blade opening hard contact cutting mode, so there is no nickel cutting, diamond shedding and accumulation, and the line saw surface is not easy to be damaged and broken. As shown in the figure, there is a clear difference from the existing blade opening process. Figure 2
