Description

  The present invention relates to a magnet processing apparatus, and more particularly to an apparatus capable of processing a magnet into a fan shape or an arc shape.

  Generally, a magnet is manufactured by a sintering method in which a fine raw material in a powder form as a material is processed and then cured at a high temperature.

  Since the magnet manufactured in this way has a very dense structure and high hardness, it is very difficult to process with a general cutting cutter. Therefore, the magnet cutting cutter is manufactured by processing steel into a disk shape and then coating industrial diamond on the steel surface.

  Such magnet processing methods are roughly divided into cutting and grinding, and the magnet can be cut by a disk cutter that rotates at high speed.

  However, it is only a linear magnet that can cut a magnet using a disk cutter. That is, when the magnet has a sector shape or an arc shape, it is very difficult to cut using a disk cutter.

  In order to solve such problems, a hexahedron magnet is processed so that a rough magnet shape is adjusted using a wire saw, and then the inner region R1 of the magnet is formed into a diamond wheel as shown in FIG. Process with. Then, the outer region R2 of the magnet is processed with a diamond wheel.

  However, in such a processing method, it is difficult to match the processing center of the inner region of the magnet with the processing center of the outer region.

FIG. 2 is a view showing a magnet processing apparatus according to the present invention.
The magnet processing apparatus of the present invention processes a magnet manufactured by a sintering method so as to have an inner diameter and an outer diameter with a predetermined radius of curvature.

  The magnet processing apparatus includes a table 100 supported by a large number of frames 110, a motor support unit 300 mounted on the table 100, and a vertical movement unit 310 for moving the motor 301 up and down. The vertical movement unit 310 is connected to the motor support unit 300, and the vertical movement unit 310 moves up and down along the motor support unit 300, so that the motor 301 also moves up and down.

  A hollow cutter 400 is attached to the end of the motor 301, and the magnet is cut while the cutter 400 is rotated by driving the motor 301.

  A portion of the cutter 400 that comes into contact with the magnet to be processed is coated with diamond with a predetermined thickness for reinforcing the strength.

  A magnet fixing means 200 is mounted at the center of the table 100, and the magnet fixing means 200 serves to fix the magnet when the accommodated magnet is cut by the cutter 400.

  The magnet processing apparatus includes a stacking unit 500 in which a magnet that is cut and falls below the magnet fixing unit 200 is accommodated. The magnet fixing means 200 is filled with cooling water for protecting the falling magnet from an impact.

  Hereinafter, the magnet fixing means of this embodiment will be described in detail.

  FIG. 3 is a plan view of the magnet fixing means according to the present invention, FIG. 4 is a diagram for explaining an operation method of the magnet machining apparatus according to the present invention, and FIGS. 5 and 6 are magnets according to the present invention. It is drawing which expanded the fixing means.

  The magnet fixing means 200 includes a large number of main bodies 210, a cylinder load 221 that moves along the guide groove 212, and a cylinder 220 that advances or retracts the cylinder load 221 toward the support rod 211.

  A support bar 211 is positioned on the extension line of the center axis of the cutter 400 at the center of the magnet fixing means 200, and a part of the upper surface of the magnet M to be processed is pressed on the upper surface of the support bar 211. A plurality of second pressure parts 241 are formed.

  The magnet that moves along the guide groove 212 is pressed in the vertical direction by the first pressure unit 230 provided on the cylinder block 231.

  A cylinder 220 for moving the magnet along the guide groove 212 and a cylinder load 221 connected to the shaft of the cylinder 220 are provided. The cylinder load 221 moves and the magnet is moved to the first pressurizing unit. When positioned below 230, the first pressurizing unit 230 descends to pressurize the upper surface of the magnet M.

  Then, the second pressurizing part 241 that is formed to protrude with a predetermined thickness on the support rod 211 presses a part of the upper surface of the magnet downward, so that the magnet to be processed becomes the cylinder load 221 and the first pressurizing part. Pressure is applied by the pressure unit 230 and the second pressure unit 241.

  As shown in FIG. 4, in the magnet machining apparatus of the present invention, the magnet M to be machined is accommodated between the cylinder blocks 231 in the guide groove 212. When the cylinder 220 is operated, the cylinder load 221 pressurizes the magnet M toward the center of the magnet fixing means.

  When the magnet M moves to the outer wall surface of the support bar 211, the first pressure unit 230 is lowered to press the magnet M downward in order to fix the position of the magnet M.

  The second pressurizing unit 241 also descends, but a part of the second pressurizing unit 241 is formed so as to protrude, so that the edge region of the upper surface of the magnet M is fixed by the second pressurizing unit 241. Is done.

  Subsequently, the cutter 400 descends while rotating like a cutting line shown in the figure, and a part of the magnet M is cut. Since the cutter 400 has a hollow circular shape, the magnet to be cut has an arc shape.

  Then, in order to discharge the cut magnet downward, the second pressurizing unit 241 moves upward by a predetermined distance, and the cylinder load 221 further pressurizes the magnet M toward the support rod 211 side, The magnet cut | disconnected through the hole formed under 2 pressurization part 241 is discharged | emitted below.

  On the other hand, a slot having a predetermined depth can be formed on the inner bottom surface of the guide groove 212 of the main body 210 in order to prevent the table 100 from being damaged by the cutter 400 when machining of the magnet by the cutter 400 is completed. .

  Two cylinder blocks 231 are arranged inside the guide groove 212 at a predetermined interval, and the first pressure unit 230 is formed on the cylinder block 231. The first pressure unit 230 may be moved up and down by a cylinder (not shown) provided in the cylinder block 231 and may have a C shape.

  On the other hand, as shown in FIG. 6, when the magnet is actually cut, a cover C that prevents particles generated at the time of cutting from flying out can be used.

  Further, a cooling hose H that discharges cooling oil can be further provided on the table 100 for cooling the heat of the cutter 400 that is generated when the magnet is processed.
