Drill screw and device for grinding the same

The present invention relates to a drill screw and its grinding device, and more particularly, the drill screw, which is a finished product made only by the forging process, to form a sharp cutting edge by a new grinding device, thereby improving the work efficiency due to excellent drill action. Drill screw and its grinding apparatus.

In general, the drill screw is made by cutting a wire material to a predetermined length and made by a rolling mill, as shown in FIG. 1, the drill screw 10 is divided into a head portion 11, a screw portion 12, a drill portion 13, and the like. And the drill portion 13 is a cutting edge 14 is formed.

Since the drill screw 10 made as described above forms the drill portion 13 into a mold, the drill cutting edge 14 may not be sharp as shown in FIG. 2, and when the mold is used for a long time, the drill cutting edge 14 may be used. ) Was further blunted and the punching capacity was lowered during use, which made it difficult for the worker.

Accordingly, an object of the present invention is to provide a drill screw having excellent performance by forming a sharp cutting edge by placing a grinding surface on the tip of a drill screw.

Another object of the present invention is to provide a grinding device for automatically grinding the grinding surface at the tip of the drill portion of the drill screw.

The present invention for achieving the above object,

A conventional drill screw in which a head, a thread, a drill, a cutting edge, and the like of a drill portion are formed by forging, has a feature of forming a sharp cutting edge by forming a grinding surface at the tip of the drill portion. .

In addition, the present invention provides a grinding surface to the supply means for supplying the drill screw conveyed to the chute to the jig device, the jig device for accurately fixing the supplied drill screw, and the cutting edge of the drill portion of the drill screw fixed to the jig device There are other features, including the first and second grinding machines to be formed.

In addition, the present invention has another feature that the supply means is provided with a forceps for picking up and transporting the drill screw one by one, a rotating means for rotating the forceps, a rail for moving the forceps and the mover is installed.

In addition, the present invention is the jig device is provided with a movable jig to move up and down and a fixed jig fixed to the lower side of the movable jig, and formed on the upper surface of the fixing jig to form a settled portion in which the drill portion of the drill screw is placed. There is this.

As described above, the drill screw of the present invention has a sharp cutting edge formed by the grinding surface, so that the punching ability is excellent in use, and the drill screw grinding device has completed the manufacture of the conventional drill screw by the forging process in manufacturing the drill screw. Next, the cutting edge of the drill screw is again ground to form a sharp cutting edge, thereby providing a drill screw with an improved drilling capability, and an additional advantage of using the forging die of the drill screw manufacturing machine for a long time. have.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

3 is an explanatory view of a drill screw according to the present invention,

In the drill screw 100 formed with the head 110, the screw 120 and the drill 130, the sharp cutting edge 140 by forming a grinding surface 150 at the tip of the drill 130 To form.

4 is an overall conceptual view of a drill screw grinding device according to the present invention,

Connected to a separate alignment device (not shown), the chute 210 for transporting the drill screw 10 and the drill screw 10 transported by the chute 210 are picked up one by one and supplied to the jig device 300. First means for grinding the cutting edge of the supply means 200, the jig device 300 for fixing the supplied drill screw 10 in the correct posture, and the drill screw 10 fixed to the jig device 300 , The second grinding machine 400, 500 is provided.

5 is a front view of the supply means 200, Figure 6 is a left side view of Figure 5,

A rail 220 is installed between the chute 210 and the jig device 300, and the mover 230 is installed on the rail 220 to be movable. The mover 230 includes the forceps 240 and the forceps 240. ) Is provided with a driving means (250) and a rotating means (260) for rotating the forceps.

The drive means 250 is composed of a pneumatic cylinder 251 and is configured to enable the forceps operation by the operation to move the forceps in and out.

The rotation means 260 is configured to rotate the pinion 263 by rotating the pinion 263 to reciprocate the rack gear 262 by the pneumatic cylinder 261 to engage the pinion 263. .

7 is a front view of the jig device 300, and FIG. 8 is a left side view of FIG.

The jig device 300 serves to accurately hold in order to grind the drill screw 10 supplied by the forceps 240, and is fixed to the movable jig 320 to be moved up and down by the cylinder 310 The fixing jig 330 is provided.

As shown in FIG. 9, the fixing jig 330 has a settled portion 331 such that the drill portion 13 of the drill screw 10 is accurately placed so that the grinding surface of the drill screw 10 can be accurately ground at a predetermined angle. ) Is formed.

The first and second grinding machines 400 and 500 rotate the cylinders 410 and 510 and the grinding plates 430 and 530 that move forward and backward to the grinding plates 430 and 530 as shown in FIG. 4. The main motors are provided with the motors 411 and 511 and are provided on the substrates 420 and 520 at predetermined angles. The first and second grinding machines 400 and 500 may be provided with an angle adjusting device for precisely adjusting the grinding angle.

Grinding device as described above is to drill the drill screw 10 of the drill screw 10 while the tongs 240 picks up the drill screw 10 gliding on the chute 210 to the drill direction toward the direction of travel. When the part 13 is placed on the settled part 331 of the fixing jig 330, the movable jig 320 descends to fix the drill screw 10, and then the cutting edge 14 of the fixed drill screw 10 is shown. By grinding the grinding plates 430 and 530 of the first and second grinding machines 400 and 500 as shown in FIG. 10, the drill screw 100 as the final object is manufactured.

Grinding device of the present invention is that there is no problem in use in the industry because it can supply a product having a sharp cutting edge formed by the grinding surface by immediately grinding the drill screw manufactured by installing in the drill screw manufacturing plant.
