본 고안은 누름판과 기체 사이에서 작동되는 안전몸체에 의하여 프레스 작업시 안전사고를 방지하게 한 프레스 안전장치에 관한 것이다.The present invention relates to a press safety device that prevents a safety accident during press work by a safety body operated between the pressing plate and the body.
종래의 프레스 안전장치는 구조가 복잡하고 동작이 정확하지 않아 안전장치가 설치되어 있어도 작업자가 안심하고 작업할 수 없었으며, 프레스 1회 공정때마다 프레스 전면에 설치된 레버가 회동하여 작업자의 팔을 쳐내게 한 안전장치가 있었으나 이것은 레버의 회동력에 의하여 팔에 외상을 입을 우려가 있었던 것이다.The conventional press safety device is complicated in structure and inaccurate operation, so even if the safety device is installed, the worker could not work safely. The lever installed on the front of the press rotates every time the press is pressed. There was a safety device in place, but this could cause injury to the arm due to the pivoting force of the lever.
본 고안은 상술한 바와 같은 프레스 안전장치의 문제점을 감안하여 공압실린더에 의하여 작동되는 안전몸체를 누름판과 하부홀더 사이에서 출몰되게 설치하여 작업중 작업자가 실수로 누름판과 하부홀더 사이에서 손을 빼지 못한 경우에는 적외선 감지구의 적외선 차단에 의하여 공압실린더의 전원이 차단되므로서 안전몸체는 누름판과 기체 사이에서 위치한 상태로 있게 되어 이 안전몸체에 의하여 누름판과 하부홀더 사이에는 일정간격이 유지되어 작업자의 팔을 보호하므로서 안전사고를 미연에 방지할 수 있게 한 것으로 첨부도면에 의거 상세히 설명하면 다음과 같다.The present invention, in view of the problems of the press safety device described above, the installation of the safety body operated by the pneumatic cylinder to stand out between the pressing plate and the lower holder when the operator accidentally pulled out the hand between the pressing plate and the lower holder during operation. The power supply of the pneumatic cylinder is cut off by the infrared cut-off of the infrared sensor, and the safety body remains positioned between the pressure plate and the body, and the safety body maintains a certain distance between the pressure plate and the lower holder to protect the arm of the worker. Therefore, the safety accident can be prevented in advance, and the detailed description based on the accompanying drawings is as follows.
상부홀더(2)와 안내공(4)이 일정간격으로 상면에 형성된 하부홀더(3)가 축설된 기체(1) 선단 양측에 스위치(11,11′)에 의하여 작동하는 공압실린더(6,6′)를 부착하고 공압실린더(6,6′) 전방부에는 적외선 감지구(13,13′)를 부착하며 공압실린더(6,6′)의 로드(7,7′) 끝단에 안전몸체(8,8′)를 부착하여 안전몸체(8,8′)를 안내하는 안내레일(9,9′)을 기체(1) 선단에 형성하고 스위치(12,12′)에 의하여 작동하는 공압실린더(10,10′)에 누름판(5)을 상부홀더(2)와 하부홀더(3) 사이에 위치하도록 축설하여서 된 것으로 도면중 미설명 부호(14)는 공작물이다.Pneumatic cylinders 6 and 6 operated by switches 11 and 11 'on both sides of the base 1 on which the upper holder 2 and the guide hole 4 formed on the upper surface at regular intervals are arranged. ′) And infrared detectors 13, 13 ′ at the front of the pneumatic cylinders (6, 6 ′) and a safety body (8) at the end of the rods (7, 7 ′) of the pneumatic cylinders (6, 6 ′). Pneumatic cylinders (10, 12 ') formed at the tip of the body (1) and guide rails (9, 9') for guiding the safety bodies (8, 8 ') by attaching. And 10 '), the pressing plate 5 is arranged so as to be positioned between the upper holder 2 and the lower holder 3, and reference numeral 14 in the figure denotes a workpiece.
이와 같이 구성된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention configured as described above are as follows.
프레스 작업시 작업자가 하부홀더(3)에서 공작물(14)을 꺼내거나 설치하기 위하여 작업을 할 때는 적외선 감지구(13,13′)의 적외선이 차단된 상태로 유지되어 공압실린더(6,6′)의 작동이 이루어지지 않게 되므로 상부홀더(2)가 하강하여도 안전몸체(8,8′)에 누름판(5)이 얹혀지게 되어 상부홀더(2)와 기체(1) 사이에는 안전몸체(8,8′) 크기만큼의 공간이 생겨 작업자의 실수로 인한 안전사고를 미연에 방지하게 되는 것이다. 하부호울더(3)에서 작업이 끝나면 적외선 차단이 해제되므로 스위치(11,11′)를 누르면 공압실린더(6,6′)의 로드(7,7′)가 당겨지면서 안전몸체(8,8′)를 안내레일(9,9′)로 안내하여 누름판(5)과 하부홀더(3) 사이에서 이탈하게 된다. 이렇게 누름판(5)과 하부홀더(3) 사이에서 안전몸체(8,8′)가 이탈된 후 스위치(12,12′)를 누르면 공압실린더(10,10′)에 의하여 누름판(5)이 하강하여 공작물(14)을 눌러줌으로서 공작물(14)의 돌설부가 안내공(4)으로 삽입되게 되고 상부홀더(2)가 하강하여 공작물(14)을 성형하게 되는데 삽입되게 되고 상부홀더(2)가 하강하여 공작물(14)을 성형하게 되는데 상부홀더(2)가 하강하여 공작물(14)을 성형하고 누름판(5)과 함께 상승하여 원위치로 되면 공압실린더(6,6′)가 작동되어 안전몸체(8,8′)가 누름판(5)과 하부홀더(3) 사이로 들어가게 되고 이때 성형된 공작물(14)을 빼내고 새로운 공작물(14)을 설치하는 작업을 하게 되는데 작업중 실수로 상부홀더(2)가 하강하여도 안전몸체(8,8′)에 의하여 누름판(5)과 기체(1) 사이에 일정간격이 유지되어 안전하게 작업을 할 수 있는 것이다. 또한 하부홀더(3) 상면에 일정간격이 안내공(4)이 다수 형성되어 있어 공작물(14)을 설치할 때 공작물(14)에 형성된 다수의 돌설부위중 양쪽끝의 돌설부의 만을 하부홀더(3)의 안내공(4)에 맞추므로서 간단히 설치할 수 있도록 한 것이다.When the operator works to remove or install the workpiece 14 from the lower holder 3 during the press work, the infrared rays of the infrared sensing ports 13 and 13 'are kept blocked so that the pneumatic cylinders 6 and 6' Since the upper holder 2 is lowered, the pressing plate 5 is placed on the safety body 8, 8 'so that the safety body 8 is not disposed between the upper holder 2 and the body 1. , 8 ′) space is created to prevent accidents due to worker's mistake. When the work is completed in the lower holder (3), the infrared cut-off is released, so when the switch (11, 11 ') is pressed, the rod (7,7') of the pneumatic cylinder (6,6 ') is pulled and the safety body (8,8') is pulled out. ) Is guided by the guide rails (9, 9 ') to be separated between the pressing plate (5) and the lower holder (3). When the safety body (8,8 ') is separated between the pressing plate (5) and the lower holder (3), the switch (12, 12') is pressed and the pressing plate (5) is lowered by the pneumatic cylinders (10, 10 '). By pressing the work piece 14, the protrusion of the work piece 14 is inserted into the guide hole 4, and the upper holder 2 descends to form the work piece 14, which is inserted into the upper holder 2. Is lowered to form the workpiece (14), the upper holder (2) is lowered to form the workpiece (14) and ascends with the pressing plate (5) to the original position when the pneumatic cylinder (6,6 ') is operated to the safety body (8,8 ') enters between the presser plate (5) and the lower holder (3), and at this time, the shaped workpiece 14 is removed and a new workpiece 14 is installed. The safety body (8,8 ') maintains a certain distance between the pressing plate (5) and the body (1) even when descending, so that you can work safely. That will. In addition, a plurality of guide holes 4 are formed at a predetermined interval on the upper surface of the lower holder 3, so that only the protrusions at both ends of the plurality of protrusions formed on the workpiece 14 when the workpiece 14 is installed are provided. The guide hole (4) of the) is to be installed easily.
이와 같이 프레스 작업시 하부홀더(3)에서 작업자의 작업이 끝나 적외선 차단이 해제되면 공압실린더(6,6′)의 작동에 의해 안전몸체(8,8′)가 누름판(5)과 하부홀더(3) 사이에서 이탈되므로서 프레스 작업에 지장을 주지 않고, 작업자가 실수로 미쳐 손을 빼지 못했을 때는 빼지 못한 손에 의해 적외선 감지구(13,13′)의 적외선 차단이 유지되어 안전몸체(8,8′)가 누름판(4)과 하부홀더(3)사이에 끼어 공간을 확보해줌으로서 작업자의 안전사고를 미연에 방지하고, 하부홀더(3)에 안내공(4)을 형성시켜 공작물(14)을 간편하게 설치할 수 있도록 한 효과가 있는 유용한 고안인 것이다.In this way, when the work is finished by the operator in the lower holder (3) when the infrared cut off is released by the operation of the pneumatic cylinder (6,6 '), the safety body (8,8') is the pressing plate (5) and the lower holder ( 3) It does not interfere with the press work as it is separated from each other, and when the worker accidentally loses his or her hand, the infrared sensor 13, 13 'is blocked by the unsuccessful hand and the safety body (8, 8 ') is interposed between the pressing plate 4 and the lower holder (3) to secure a space to prevent accidents of the worker in advance, and to form a guide hole (4) in the lower holder (3) It is a useful design that has the effect of making it easy to install.
