본 발명은 방전가공기용 가공탱크 도어개폐장치에 관한 것으로, 더욱 구체적으로 가공탱크의 도어를 회동식이 아닌 상하이동형으로 제작하여 도어의 개폐시 필요한 공간을 최소화하고, 잠금장치의 구조를 간단히 하여 사용이 간편한 도어개폐장치에 관한 것이다.The present invention relates to a processing tank door opening and closing device for electric discharge machining machine, and more specifically, to make the door of the processing tank in a shanghai type instead of a rotating type, to minimize the space required for opening and closing the door, and to simplify the structure of the locking device. It relates to a simple door opening and closing device.

일반적으로 초경합금 등과 같이 비교적 단단한 소재의 정밀 가공 및 금형 등의 정밀한 가공을 요하는 경우 와이어컷 방전 가공을 사용한다. 와이어컷 방전 가공은 와이어에 마이너스 전류를 가하고 가공물에 플러스 전류를 가하면서 와이어와 가공물 사이에 발생되는 펄스방전에 의해 소정의 형상으로 가공한다. Generally, wire cut electric discharge machining is used when precision machining of relatively hard materials such as cemented carbide and precise processing such as molds are required. The wire cut discharge machining is processed into a predetermined shape by pulse discharge generated between the wire and the workpiece while applying a negative current to the wire and a positive current to the workpiece.

와이어컷 방전가공기는 분사식과 침적식으로 구분되는데, 침적식은 가공액에 가공물이 잠기게 한 상태로서 가공정도가 보다 정밀하다는 장점이 있다.Wire cut electric discharge machining machine is divided into spray type and immersion type, immersion type has the advantage that the degree of processing is more accurate as the workpiece is immersed in the processing liquid.

이러한 침적식 방전가공기의 가공탱크 도어개폐장치는 일반적으로 회동식으로 구성되어 있으므로 도어의 개폐시 회전반경에 따른 공간이 필요하다. 따라서 도어의 크기가 큰 경우 그만큼의 공간이 필요하여 가공탱크의 설치장소의 면적이 증가하게 된다. 또한 가공탱크의 내부에 존재하는 가공액 등의 누수를 방지하기 위한 잠금장치는 클래스퍼를 이용하여 사용이 불편한 문제가 있다. Since the process tank door opening and closing device of the immersion type electric discharge machine is generally composed of a rotation type, space according to the rotation radius is required when opening and closing the door. Therefore, if the size of the door is large, the space is required to increase the area of the installation place of the processing tank. In addition, the locking device for preventing the leakage of the processing liquid and the like present in the processing tank has a problem that it is inconvenient to use the classer.

이러한 문제점을 해결하기 위하여 본 발명은 안출된 것으로서, 본 발명의 목적은 도어를 상하이동식으로 구성하여 도어개폐시 필요한 공간을 줄이고, 패킹 및고리와 손잡이겸용 후크로 잠금수단를 형성하여 간편하게 누수를 방지할 수 있는 방전가공기용 가공탱크의 도어개폐장치를 제공하는데 있다.In order to solve this problem, the present invention has been made, the object of the present invention is to configure the door in Shanghai-dong to reduce the space required for opening and closing the door, and to form a locking means with a packing and hook and handle hook to easily prevent leakage The present invention provides a door opening and closing device for a processing tank for an electric discharge machine.

본 발명인 방전가공기용 가공탱크의 도어 개폐장치는 가공탱크(2)의 내부물질의 누수를 방지하는 도어(10), 도어(10)와 연결되어 회전운동하면서 도어(10)를 승강 안내하는 도어 승강안내수단 및 도어(10)를 상승 위치에서 고정시키는 도어 잠금수단으로 구성되어 있다.The door opening and closing device of the processing tank for the electric discharge machining device of the present invention is connected to the door 10, the door 10 to prevent the leakage of the internal material of the processing tank (2) while lifting the door to lift and guide the door (10) It consists of a door locking means for fixing the guide means and the door 10 in the raised position.

상기 도어 승강안내수단은 도어(10)의 승강 영역 양쪽에 배치되어 도어(10)에 연결된 궤도형 휠수단(20) 및 상기 궤도형 휠수단(20)의 상하 양끝의 안쪽에 위치하여 상기 휠수단의 회전을 지지하는 휠 지지수단(24, 26)을 포함함이 바람직하다.The door elevating guide means is disposed on both sides of the elevating area of the door 10 and is located inside the upper and lower ends of the tracked wheel means 20 and the tracked wheel means 20 connected to the door 10. It is preferable to include the wheel support means 24, 26 for supporting the rotation of the.

이때, 궤도형 휠수단(20)에 밸런스 웨이트가 더 장착되는 것이 바람직하다.At this time, the balance weight is preferably mounted on the track type wheel means 20.

상기 도어 잠금수단은 도어(10)의 양단에 힌지 연결되고, 일단에 손잡이(36)를 구비하고 타단에 걸이구멍(32a)을 갖는 손잡이겸용 후크(32); 및 도어(10)를 상승하여 상기 손잡이겸용 후크(32)를 하강 회전시킬시 상기 걸이구멍(32a)에 강제로 끼워넣어지도록 가공탱크(2)에 장착된 후크걸이용 핀(31);으로 구성됨이 바람직하다.The door locking means is hinged to both ends of the door (10), having a handle 36 at one end and the handle combined hook 32 having a hook hole (32a) at the other end; And hook hook pins 31 mounted to the processing tank 2 to be forcibly fitted into the hook holes 32a when the door 10 is raised and lowered to rotate the dual handle 32 hook. This is preferred.

이하, 첨부된 도면을 참고하여 본 발명인 방전가공기용 상하이동식 도어개폐장치의 동작원리 및 바람직한 실시예를 구체적으로 살펴본다.Hereinafter, with reference to the accompanying drawings looks at in detail the operating principle and preferred embodiment of the present invention shanghai dynamic door opening and closing device.

도 1은 본 발명인 방전가공기용 상하이동식 도어개폐장치의 구성도이고, 도 2는 가공탱크에 본 발명인 도어개폐장치가 설치된 상태를 나타내며, 도 3은 도어개폐장치가 설치된 측면도를 나타낸다.1 is a block diagram of the Shanghai East-type door opening and closing device for the electric discharge machine of the present invention, Figure 2 shows a state in which the door opening and closing device of the present invention is installed in the processing tank, Figure 3 shows a side view of the door opening and closing device is installed.

도어(10)는 가공탱크(2)의 전면을 덮을 수 있는 크기로서 일체형이며, 도어브라켓(12)으로 궤도형 휠수단(20)에 고정연결된다.The door 10 is integrally sized to cover the front surface of the processing tank 2 and is fixedly connected to the track-type wheel means 20 by the door bracket 12.

또한 도어(10)와 가공탱크(2)사이의 틈에는 도 5에 나타난 바와 같이, 패킹(14)을 더 형성함이 바람직하다. 패킹(14)이 없는 경우 도어(10)와 가공탱크 사이의 틈새 사이로 가공액이 누출될 수 있기 때문에 패킹(14)을 도어(10)의 내면에 장착시켜 이를 방지하기 위함이다.In addition, the gap between the door 10 and the processing tank 2, as shown in Figure 5, it is preferable to further form a packing (14). If the packing 14 is not present, the processing liquid may leak between the gap between the door 10 and the processing tank, so that the packing 14 may be mounted on the inner surface of the door 10 to prevent this.

도어 승강안내수단은 상기 도어(10)의 일단이 고정연결되는 궤도형 휠수단(20) 및 궤도형 휠수단(20)를 회전구동시키는 휠 지지수단(24,26)으로 구성되어 있다.The door elevating guide means is composed of a wheel-type wheel means 20, one end of which is fixedly connected to the door 10 and wheel support means (24, 26) for driving the track-type wheel means 20.

이때 휠 지지수단(24, 26)은 풀리, 스프라켓 휠 등이 사용될 수 있고 궤도형 휠수단(20)은 로프, 벨트, 체인 등이 사용될 수 있다. 물론 휠 지지수단 및 궤도형 휠수단은 도어의 회전구동을 위한 것인바 상기예에 국한되지 않음은 물론이다.At this time, the wheel support means 24, 26 may be used pulleys, sprocket wheels, etc. The tracked wheel means 20 may be used, such as ropes, belts, chains. Of course, the wheel support means and the track-type wheel means for the rotational drive of the door is not limited to the above examples, of course.

도어 승강안내수단은 도어(10)의 승강 영역 양쪽에 형성되어 도어(10)를 구동시키며, 가공탱크(2)의 양쪽에 형성된 하부휠 지지수단(26)은 샤프트(40)로 연결됨이 바람직하다. 샤프트(40)의 연결이 없는 경우, 좌측에 형성된 하부휠 지지수 단(26)과 우측에 형성된 하부휠 지지수단(26)의 구동 정도가 달라진다. 따라서 도어(10)가 양쪽이 동일한 정도로 열리지 않게 되어 고장을 유발하기 쉽기 때문에 샤프트(40)를 연결하여 구동 정도를 동일하게 함으로써 도어(10)의 개폐 안정성을 증대시킬 수 있다. 물론 샤프트(40)는 하부휠 지지수단(26) 뿐만 아니라 가공탱크(2)의 양쪽에 형성된 상부휠 지지수단(24)를 연결하는 방식으로 구성될 수도 있다.Door lifting guide means are formed on both sides of the lifting area of the door 10 to drive the door 10, the lower wheel support means 26 formed on both sides of the processing tank (2) is preferably connected to the shaft (40). . If there is no connection of the shaft 40, the driving degree of the lower wheel support means 26 formed on the left side and the lower wheel support means 26 formed on the right side is different. Therefore, since both doors 10 are not opened to the same extent and are easy to cause a failure, the opening and closing stability of the door 10 can be increased by connecting the shaft 40 to the same driving degree. Of course, the shaft 40 may be configured in such a manner as to connect the lower wheel support means 26 as well as the upper wheel support means 24 formed on both sides of the processing tank 2.

또한, 도 4a에 나타난 바와 같이, 도어 승강안내수단으로서 궤도형 휠수단(20)에 밸런스 웨이트(50)가 더 장착되어 구성됨이 바람직하다. 밸런스 웨이트(50)는 도어(10)의 이동과 반대로 움직이면서 도어(10)의 개폐시 구동안정성을 더 증대시키는 역할을 한다. In addition, as shown in Figure 4a, it is preferable that the balance weight 50 is further mounted to the track-type wheel means 20 as the door lift guide means. The balance weight 50 serves to further increase driving stability when the door 10 is opened and closed while moving opposite to the movement of the door 10.

가이드부재(22)는 궤도형 휠수단(20)의 이동시 궤도형 휠수단(20)의 한쪽에 고정된 도어(10)의 무게 등으로 안정성이 떨어지기 때문에 궤도형 휠수단(20)의 이동시 흔들림을 방지하고 구동상의 안정성을 증대시키기 위하여 설치함이 바람직하다.The guide member 22 is shaken when the tracked wheel means 20 moves because the stability decreases due to the weight of the door 10 fixed to one side of the tracked wheel means 20 when the tracked wheel means 20 moves. It is desirable to install in order to prevent the damage and to increase the stability of the driving.

도어 잠금수단은 도어 양단에 힌지 연결되고, 일단에 손잡이(36)를 구비하고 타단에 걸이구멍(32a)을 갖는 손잡이겸용 후크(32)를 가공탱크(2)에 장착된 고리부(30)의 후크걸이용 핀(31)에 고정시킴으로써, 패킹(14)을 더 밀착시켜 내부물질의 누수방지 효과를 증대시킨다. 또한 고리부(30) 및 손잡이겸용 후크(32)로 구성된 구조의 단순함으로 사용자의 편리함을 도모할 수 있다.The door locking means is hinged at both ends of the door, and has a handle 36 at one end and a hook-and-hook hook 32 having a hook hole 32a at the other end of the hook portion 30 mounted on the processing tank 2. By fixing to the hook pin 31 for the hook, the packing 14 is further in close contact to increase the leakage preventing effect of the internal material. In addition, by the simplicity of the structure consisting of the hook portion 30 and the combined handle 32 can facilitate the user's convenience.

또한 도어 잠금수단은 도어(10)의 일측에 형성될 수 있으나, 보다 바람직하게 양쪽에 형성한다. 뿐만 아니라 잠금수단을 도어(10)의 좌우에 위치시키는 경우 뿐만 아니라 도어(10)의 상하에도 위치시킬 수 있음은 물론이다.In addition, the door locking means may be formed on one side of the door 10, but more preferably formed on both sides. In addition, the locking means may be positioned not only on the left and right sides of the door 10 but also on the top and bottom of the door 10.

이하, 첨부도면을 참고하여 본 발명인 방전가공기용 상하이동식 도어개폐장치의 동작원리를 살펴보면 다음과 같다.Hereinafter, with reference to the accompanying drawings look at the operating principle of the present invention Shanghai East-type door opening and closing device for electric discharge machine.

도 4는 도어(10)의 상하이동을 측면에서 바라본 것이다. 도 4a는 도어(10)가 닫힌상태를 나타내고, 도 4b는 도어(10)가 열린상태를 나타낸다. 4 is a side view of the shanghai-dong of the door 10. 4A shows a state in which the door 10 is closed, and FIG. 4B shows a state in which the door 10 is opened.

도어 승강안내수단의 동작으로서 문이 열리는 원리는 다음과 같다. 상부휠 지지수단(24)이 반시계방향으로 구동(즉, 하부휠 지지수단(26)은 시계방향으로 구동)되면 밸런스 웨이트(50)은 상부로 이동하고, 도어(10)는 가공탱크의 하부로 내려오면서 도어(10)가 열린상태가 된다. 역으로 동작시 도어(10)는 닫힌상태가 된다.The principle of opening the door as the operation of the door lift guide means is as follows. When the upper wheel support means 24 is driven counterclockwise (that is, the lower wheel support means 26 is driven clockwise), the balance weight 50 moves upwards, and the door 10 moves to the bottom of the processing tank. The door 10 is opened while descending to. In reverse operation, the door 10 is closed.

도 6은 잠금수단의 작동상태를 나타낸 것이다. 도 6a는 도어(10)가 닫힌 위치에서 잠기지 않은 상태이고, 도 6b는 도어(10)가 닫힌위치에서 잠긴 상태를 나타낸다.Figure 6 shows the operating state of the locking means. FIG. 6A shows a state in which the door 10 is not locked in the closed position, and FIG. 6B shows a state in which the door 10 is locked in the closed position.

손잡이겸용 후크(32)는 고정힌지(34)에 의하여 도어(10)의 측면에 연결되어 있으므로, 손잡이(36)를 아래로 내리면 고정힌지(34)를 축으로 하여 걸이구멍(32a)이 가공탱크(2)에 고정부착된 고리부(30)의 후크걸이용 핀(31)에 걸리게 되는 것이다. 이와 같은 잠금수단으로써 도어(10)와 가공탱크 사이에 형성된 패킹(14)이 더욱 밀착되고 도어(10)의 잠금상태를 고정시킬 수 있다.Since the dual handle hook 32 is connected to the side surface of the door 10 by the fixed hinge 34, when the handle 36 is lowered, the hook hole 32a is rotated around the fixed hinge 34 as the processing tank. (2) is hooked to the hook hook pin 31 of the ring portion 30 is fixed. As the locking means, the packing 14 formed between the door 10 and the processing tank may be in close contact with each other to fix the locked state of the door 10.

본 발명이 방전가공기용 가공탱크의 도어 개폐의 경우에 대하여 설명하였으나 내부 물질의 누수를 방지하고 공간의 활용이 우수한 개폐장치를 요구하는 어떠 한 공작기계에도 본 발명인 상하이동식 도어개폐장치가 사용될 수 있음은 물론이다.Although the present invention has been described in the case of opening and closing the door of the processing tank for the electric discharge machine, the Shanghai-type door opening and closing device of the present invention can be used for any machine tool that prevents leakage of internal materials and requires an opening and closing device having excellent space utilization. Of course.

이상 설명한 바와 같이, 본 발명에 따르면 도어를 상하이동식으로 구성함으로써 회동식 도어의 개폐시 필요한 공간을 절약할 수 있으며, 도어에 패킹 및 고정수단으로서 손잡이겸용 후크와 고리부를 사용함으로써 사용자가 손쉽게 가공탱크 내부에 존재하는 가공액의 누수를 방지할 수 있는 장점이 있다. As described above, according to the present invention, by configuring the door in Shanghai-type, the space required for opening and closing the rotating door can be saved, and the user can easily process the processing tank by using a hook and a hook part as a means for packing and fixing the door. There is an advantage that can prevent the leakage of the processing liquid present inside.

비록 본 발명이 상기에서 언급한 바람직한 실시예와 관련하여 설명되어졌지만, 본 발명의 요지와 범위로부터 벗어남이 없이 다른 다양한 수정 및 변형이 가능한 것은 당업자라면 용이하게 인식할 수 있을 것이며, 이러한 변경 및 수정은 모두 첨부된 특허청구의 범위에 속함은 자명하다.Although the present invention has been described in connection with the above-mentioned preferred embodiments, it will be readily apparent to those skilled in the art that various other modifications and variations are possible without departing from the spirit and scope of the invention. Are all within the scope of the appended claims.
