Referring to the drawings, as shown in Figures 4 and 5 when the movement of the rail is stopped and positioned in front of the front deburring device 200 and the base 30; A plurality of grinders 27 are installed on the upper surface of the base 30 to remove burrs generated in the through hole 41, and the power is transmitted from the driving source 29 installed on the upper portion of the base 30. Receiving multiaxial head 31; A hydraulic cylinder (23) installed at an upper end of the base (30) perpendicular to the upper surface of the base (30); A moving plate 21 attached to the upper side of the base 30 and moved forward or backward in the vertical direction of the base 30 by an air cylinder 24 installed above the base 30; and the moving plate A support part 35 attached to the upper part 21 to fix the polishing means 26; and a drive symmetrically installed in the longitudinal direction of the polishing part 26 coupled to the moving plate 21 to supply a power source; The front deburring device 200 comprising a means 25 and grinding means 26 for interlocking with the driving means 25 to remove the burr of the rail is provided by the hydraulic cylinder 23. The burr generated in the front grinding portion 20 and the through hole 41 of the rail 40 including the grinding means 26 mounted on the support portion 35 is removed from the front 42 and the uneven portion of the The base 30 equipped with the multi-axis head 31 equipped with the grinder 27 for removal is a hydraulic seal as shown in FIG. 5B. By more than 23 to rise. The multi-axis head 31 distributes the kinetic energy received from the driving source 29 to the grinders 27 disposed in the through holes 41 of the rail 40, respectively, to generate burrs generated in the respective through holes 41. To be removed at the same time.

And, in order to remove the burr generated on the front face 42 of the rail 40, the front polishing part 20 is equipped with a movable plate 21 at the bottom, operation according to another embodiment of the front deburring device 200 6A and 6B, the air cylinder is directed in a direction passing through the front of the rail at a right angle so that the grinding means 26 removes burrs generated on the front 42 of the rail 40. As shown in FIGS. It moves by moving the moving plate 21 mounted in the lower part of the said front grinding | polishing part 20 through 24. As shown in FIG. As shown in FIG. 4, in the front polishing unit 20, driving means 25 symmetrically installed in the longitudinal direction of the moving plate 21 is coupled to the pulley 33, and the pulley 33 of each driving means 25 is connected. The pulley 33 connected to the grinding means 26 is connected to the power transmission means 34. As the driving means 25 is rotated in the same direction as the two side deburring apparatus 100, the two grinding means 26 are rotated in opposite directions to each other and the rail (a) along the movable plate 21. The front face 42 of 40 is ground at right angles and the burr is removed. After removing the burrs generated in the through hole 41 and the front face 42 of the rail 40, the front deburring device 200 moves to the original position as shown in Figs. 5A and 6A to move the rail and move the next rail. waiting. The rail with the through hole and the front burr removed is moved through the transfer frame 50 to the next process after being moved back to the conveyor.

On the other hand, the vertical movement method of the front deburring device 200 is implemented in two forms. First, as shown in FIGS. 5A and 5B, at least one hydraulic cylinder 23 is installed on both sides of the base 30 in the longitudinal direction to lift directly. And secondly, FIG. 7 which is a perspective view showing the modified lift 32 structure of the front deburring device 200 of the present invention, and an operation state of the modified lift 32 of the front deburring device 200. As shown in FIG. 8, a cylinder is installed on only one side and lifted using a lift 32 connected with a link. In the former method, due to the different loads of the respective parts of the base 30, the base 30 may be slightly twisted over time, and a slight time difference may occur when each hydraulic cylinder 23 rises. Due to this, there is a possibility that a deviation occurs in the deburring of the through hole 41, and thus the second method has come out as an improved type to distribute the load.

In the deburring device, the burr of the rail is not large and hard enough to use a disc, and is sized enough to be removed by a brush. Therefore, the brush is adopted as a grinding means, and the grinder 27 is used to remove burrs of the through hole. Counter sinker was adopted.

Hereinafter, the deburring method of the rail of the present invention by the deburring device of the rail of the present invention having the configuration and action as described above will be described in detail with reference to FIG.

Then, the rails entered through the automated conveyor apparatus are transferred by converting the rails in the vertical direction through the automated conveyor apparatus (the transfer frame and the thermal frame) installed perpendicular to the entrance direction of the rail (transfer step, Step S 102).

Then, the rail conveyed with the entry direction changed is temporarily stopped, and the side surface of the side surface of the flat plate portion is deburred using a deburring device provided with polishing means (side deburring step, step S 103).

After that, the rails having the flat plate side deburred are re-transmitted and paused, and the polishing means is provided at the cross section of the front face of the flat plate, the cross section of the front face of the vertical beam, and the perimeter of the through hole of the bottom of the flat plate. Deburring is carried out using a deburring apparatus (front and through hole deburring step, step S 104).

In addition to the method further comprises the step of discharging the rail passing through the front and through-hole deburring step through an automated conveyor device installed perpendicular to the conveying direction of the rail (discharge step, step S 105) It is preferable.

On the other hand, the embodiments of the present invention disclosed in the specification and drawings are merely presented specific examples to aid understanding, and are not intended to limit the scope of the present invention.
