본 발명은 변압기의 코어와 같이 박판소재의 철판이나 동판을 원하는 크기대로 절단하는 과정에서 발생하는 버(burr)를 제거하기 위한 버 제거장치에 관한 것으로, 더욱 상세하게는 동판의 양측을 절단함으로써 발생되는 동판의 휨이나 절단부위의 버를 제거함으로써 변압기의 제품불량을 해소할 수 있는 버 제거장치에 관한 것이다.The present invention relates to a burr removing device for removing a burr generated in the process of cutting a steel plate or copper plate of a thin plate material to a desired size, such as the core of the transformer, more specifically generated by cutting both sides of the copper plate The present invention relates to a burr removing device capable of eliminating product defects in a transformer by removing burrs in a copper plate and cutting portions.

일반적으로 버(burr)는 판상의 물체를 절단장치로 절단을 하였을 때, 절단면에 발생하는 칩들이 절단면의 표면으로 돌출되어 가시와 같은 형태를 이루는 것을 말하며, 보통의 경우 이러한 버는 통상적으로 별도의 롤러를 통과시켜 판상의 물체를 눌러줌으로써 판상물체의 평활면을 수정하고 양측의 가시와 같은 부분을 마모시켜 형성한다.In general, when a burr cuts a plate-like object with a cutting device, chips generated on the cutting surface protrude to the surface of the cutting surface to form a barbed shape. Usually, such burrs are usually separate rollers. By pressing the plate-like object through the through to correct the smooth surface of the plate-like object is formed by wearing parts such as thorns on both sides.

이하, 첨부된 도면을 참조하여 박판소재(이하, "동판"이라 한다)의 절단부분에 발생되는 버를 제거하기 위한 종래의 버 제거장치(deburrer)를 설명한다.Hereinafter, with reference to the accompanying drawings will be described a conventional burr remover (deburrer) for removing the burrs generated in the cut portion of the thin plate material (hereinafter referred to as "copper plate").

도 1은 종래의 동판을 절단하는 과정의 개략도이고, 도 2는 도 1의 개략도중 절단롤러의 정면도이며, 도 3a 내지 도 3b는 동판이 절단롤러에 의하여 절단된 상태의 확대 단면도이다.1 is a schematic view of a process of cutting a conventional copper plate, Figure 2 is a front view of a cutting roller in the schematic view of Figure 1, Figures 3a to 3b is an enlarged cross-sectional view of the copper plate is cut by the cutting roller.

도시한 바와 같이 권출롤러(1)에 감겨 보관 및 이송되는 동판(2)은 이송수단(미도시)에 의하여 절단롤러(3)측으로 이송되어 양측이 설정된 폭으로 절단되고, 이어서 직물롤러(4)를 통과하며 절단과정에서 발생한 칩들을 제거한 후 가압롤러(5)를 지나면서 가시 모양으로 돌출된 버를 제거하여 권취롤러(6)에 감아 완성한다.As shown in the drawing, the copper plate 2 wound and stored on the unwinding roller 1 is transferred to the cutting roller 3 side by a conveying means (not shown), and both sides are cut to a predetermined width, and then the fabric roller 4 After passing through and removing the chips generated in the cutting process passing through the pressure roller (5) to remove the bur which is projected in the shape of a spin to finish the winding roller (6).

여기서, 상기 절단롤러(3)는 도 2에 도시한 바와 같이 절단날(3a')이 형성된 상부롤러(3a)와 상기 절단날(3a')과 내측에 근접하여 유입되는 동판을 지지하는 지지판(3b')이 형성된 하부롤러(3b)로 이루어지는데, 절단날(3a')과 지지판(3b')을 절단하려는 동판의 폭만큼 이동시켜 고정하고 이 사이에 동판을 유입시켜 절단한다.Here, the cutting roller 3 is a support plate for supporting the copper plate flowing in close proximity to the upper roller (3a) and the cutting blade (3a ') formed with a cutting blade (3a') as shown in FIG. 3b ') is formed, the lower roller (3b) is formed, the cutting blade (3a') and the support plate (3b ') is moved by the width of the copper plate to be cut and fixed, and the copper plate is introduced between the cutting.

이때, 절단되는 동판은 도 3a에 도시한 바와 같이 상기 절단날(3a')이 동판을 누르면서 절단함으로써 상부에 돌출면(2a)이 생겨 동판을 평활하게 유지하기 어 려우며, 또한, 양측 절단면에는 가시와 같은 형상의 버(2b)가 형성된다.In this case, as shown in FIG. 3A, the cutting blade 3a 'is cut while pressing the copper plate, so that a protruding surface 2a is formed on the upper part, and thus it is difficult to keep the copper plate smooth. Burs 2b having a shape like a spine are formed.

상기와 같이 형성된 동판을 다시 직물롤러(4)를 통과시켜 칩을 제거하고 가압롤러(5)를 통하여 동판을 누름으로써 동판을 평활하게 형성함과 동시에 버를 제거하고 있다.The copper plate formed as described above is passed through the fabric roller 4 to remove the chip and presses the copper plate through the pressure roller 5 to smoothly form the copper plate and remove burrs.

그러나, 상기와 같이 직물롤러(4)로 칩을 제거하고 가압롤러(5)를 이용하는 버 제거수단은 다음과 같은 문제점이 발생하였다.However, as described above, the burr removing means using the pressure roller 5 to remove the chip with the fabric roller (4) has the following problems.
