Description
Technical Field
[0001] The utility model relates to the technical field of electroplated diamond wires, in particular to an electroplated diamond wire sanding system with an electromagnetic device. Background Art
[0002] Electroplated diamond wire has been widely developed and applied due to its advantages of low loss, high efficiency and high precision in the processing of brittle and hard materials. The sanding process of electroplated diamond wire saw mainly adopts the following different methods, including falling sand method, buried sand method and brush plating method. In the buried sand method, the base of the wire saw is placed in the diamond powder to achieve sanding. The falling sand method involves immersing the wire saw base in the plating solution and allowing the diamond powder suspended in the surface of the plating solution to sink to the base to complete the sanding. As for the brush plating method, a brush is used in the electroplating tank, and the purpose of sanding is achieved by the rotating action of the brush.
[0003] The falling sand method is the most commonly used sanding process for electroplated diamond wire in the industry. As a simple sanding method for electroplated diamond wire, the falling sand method is widely used in the production process of electroplated diamond wire. In the actual production process, in order to improve production efficiency, magnetic fields, dispersants and other methods are often used to promote sanding efficiency and thus increase production line production speed. Figure 1 However, in the sanding process, the difference in magnetic field strength between individual permanent magnets can lead to uneven sanding, sand separation, and diamond stacking on the surface of the electroplated diamond wire. Adding additional dispersants in the sanding process can easily lead to uncontrolled plating solution stress, increased electrochemical byproducts, and other plating solution quality problems.
[0004] Therefore, it is necessary to improve the existing sand dropping method to improve the sand loading efficiency without affecting the quality of the plating solution. In view of this, it is necessary to propose a new technical solution to solve the above technical problems. Utility Model Content

[0026] An electroplated diamond wire sanding system with an electromagnetic device comprises an upper sanding trough, at least two electromagnetic devices and at least two upper sanding conductive rollers, wherein the electromagnetic device comprises a coil and a constant potentiostat, wherein both ends of the coil are connected to the constant potentiostat, the coil is arranged at one end or both ends of the upper sanding trough, the electroplated diamond wire passes through the coil, the constant potentiostat supplies power to the coil, and a magnetic field is generated inside the coil to magnetize the electroplated diamond wire passing through the coil; the constant potentiostat can change the current direction and current magnitude of the coil, and the number of turns of the coil and the position of the coil and the electroplated diamond wire can be relatively changed.
[0027] The utility model uses an electromagnetic device to replace the permanent magnet, which can effectively prevent the problems of permanent magnet magnetism decline, difference in magnetic field strength between permanent magnets, etc.; the strength of the electromagnetic field generated by the electromagnetic device is only related to the number of coil turns and the current size, and a stable and uniform electromagnetic field can be generated by a constant current and the number of coil turns; according to the requirements of the magnetization degree of the electroplated diamond wire, the current direction, current size, number of coil turns, and the relative position of the coil and the electroplated diamond wire can be changed, thereby changing the size and direction of the electromagnetic field, and then changing the magnetization degree of the electroplated diamond wire, thereby improving the sanding effect.
[0028] Example
[0029] See also Figures 2 to 4 The utility model provides an electroplated diamond wire sanding system with an electromagnetic device, comprising an upper sanding trough 1, four electromagnetic devices 2 and two upper sanding conductive rollers 3, the electromagnetic device 2 comprising a coil 21 and a constant potentiostat (not shown), both ends of the coil 21 are connected to the constant potentiostat, four coils 21 are evenly arranged at both ends of the upper sanding trough 1, an electroplated diamond wire 4 passes through the coil 21, the constant potentiostat supplies power to the coil 21, a magnetic field is generated inside the coil 21 to magnetize the electroplated diamond wire 4 passing through the coil 21; the constant potentiostat can change the current direction and current size of the coil 21, and the number of turns of the coil 21 and the position of the coil 21 and the electroplated diamond wire 4 can be relatively changed.
[0030] More specifically, see Figures 2 to 4 The coil 21 is composed of an insulating rubber ring 211 and a wire 212 wound on the insulating rubber ring 211. The wire 212 is made of copper or aluminum. Preferably, the wire 212 is made of copper. The wire 212 of the coil 21 is provided with two electrode interfaces 213, and the electrode interface 213 is electrically connected to the constant potential instrument. The shape of the coil 21 is one of a rectangle, a square, and a circle. Preferably, the shape of the coil 21 is a rectangle.
[0031] According to the requirements of the magnetization degree of the electroplated diamond wire 4, the electromagnetic field strength of the electromagnetic device 2 can be adjusted from the following three aspects. According to the Biot-Savart law, the magnitude of the magnetic induction intensity B at a point P in space is related to the following factors: first, it is directly proportional to the magnitude of the current element I; second, it is directly proportional to the sine value of the angle between the line from the location of the current element I to point P and the current element I; third, it is inversely proportional to the square of the distance from the current element I to point P. In short, under the same current, the magnitude of the spatial magnetic field intensity excited by the coil is positively correlated with the magnitude of the current passing through the coil; the magnitude of the spatial magnetic field intensity excited by the coil is positively correlated with the distance of the coil; in addition, according to the magnetic induction intensity formula B = μNI / L (B: magnetic induction intensity, I: current, μ: magnetic permeability in vacuum), it can be seen that under the same current, the magnitude of the magnetic induction intensity excited by the coil is positively correlated with the number of turns of the coil. Therefore, the magnitude and direction of the electromagnetic field can be changed by controlling the current direction, current magnitude, number of turns of the coil, and the relative position of the coil and the electroplated diamond wire 4, thereby changing the magnetization degree of the electroplated diamond wire 4.
[0032] The output voltage of the potentiostat is 0.1-300V, and the output current is 0.01-10A. Preferably, the output current of the potentiostat is 0.05-1A. The number of turns of the coil 21 is 2-500. Preferably, the number of turns of the coil 21 is 50 or 100.
