In this case, the ducts 123, 125, and 127 have a narrow width at the bottom thereof so that the discharged air can be concentrated on the base material 22, and have a long shape so as to discharge hot air in a wide range with respect to the traveling direction. .

Looking at the operation of the diamond tool manufacturing apparatus with reference to Figure 13 is a flow chart illustrating a manufacturing process of the diamond tool according to the present invention configured as described above are as follows.

First, the worker cleans the surface of the base material 22 used as the material of the shank to remove foreign substances such as dust or oil, and then removes water (see S10). Next, the base material prepared to be used for the work is introduced into the inclined portion 92 of the individual separator 90 by the ball feeder.

At this time, the base material 22 is individually supplied to the base material supply part 80 by three shielding plates 92a, 92b and 92c installed in the individual separator 90 and sequentially operated. The base material 22 supplied in this manner is mounted on the mounting arm 86 of the base material supply part 80 and then mounted on the support member 62 of the moving means.

Thereafter, the supporting member 62 is moved in the conveying direction by the second cylinder 65, and the guide plate 67 installed in the base unit 50 is moved toward the supporting member 62. The drive rod 71 of the drive roller 68 mounted on the plate 67 is fixed to the side of the base material 22. At this time, the drive roller 68 is rotated by the drive motor 69 mounted on the guide plate 67 to rotate the base material (22). As such, when the base material 22 is fixed by the driving rod 71, the support member 62 is moved downward by the first cylinder 63, and then by the second cylinder 65. Is moved backwards. Next, the first cylinder 63 is repeatedly raised to supply the base material 22 (see S11).

The base material 22 supplied as described above is advanced one by one by the movement of the support member 62 and the guide plate 67 and is transferred to the paste coating part 100. The paste applicator 100 applies a paste 24 having a uniform thickness to the surface of the base material 22 using a metered discharge machine (see S12).

In this way, the base material 22 to which the paste 24 is applied is advanced by the transfer means 60, and the excess paste 24 is removed by passing through the leveler and applied with a uniform thickness (see S13). Next, the base material 22 is passed through the initial drying unit 122 to perform initial drying so that the surface of the paste 24 is dried (see S14).

Next, the base material 22 is passed through the abrasive dispersion unit 110 and diamond abrasive grains are dispersed by using a porous screen or a perforated plate to disperse the diamond abrasive grains or spraying the diamond abrasive grains using a sanding machine. After attaching to the surface of the paste 24 (see S15), the paste 24 is dried by passing through the chaebol drying unit 124 (see S16).

After the paste 24 is dried as described above, the paste 24 passes through the seating part installed at the rear part of the chaebol drying unit 124 and presses the diamond abrasive grain attached to the base material 22 so as to be firmly bound with the paste 24 (S17). Reference). Next, the base material 22 passes through the final drying part 126 to completely dry the paste 24 (see S18).

The base material 22, which has undergone the above-described process, is discharged to the outside through the discharge means which is conveyed by the moving means and formed to be inclined downward (see S19). On the other hand, the base material 22 discharged from the diamond tool manufacturing apparatus according to the present invention performs a brazing process for sintering the paste 24 to the base material 22 to produce a diamond tool of the finished product (see S20).

As described above with reference to the drawings illustrated a device for manufacturing a diamond tool according to the present invention, the present invention is not limited by the embodiments and drawings described above, the scope of the invention within the claims Of course, various modifications and variations can be made by those skilled in the art.

The apparatus for manufacturing a diamond tool according to the present invention configured as described above is performed in a series of processes for manufacturing a diamond tool continuously, thereby increasing productivity and maintaining the same working conditions, thereby improving quality. In addition, since each process is performed in one device, not only the time required for moving, storing, and loading the base metal is reduced, but also mass production is possible, and the material cost is reduced because the paste for attaching the diamond abrasive is fixedly discharged. Can be reduced.
