본 발명은 각종 프레스기의 상부 금형을 부착하는 샹크에 부착 판넬을 끼우고 타단에 안전장치를 고정시켜서 상부금형이 내려오는 순간, 밀대가 순간적으로 회전하여 하부금형 위치에 있는 작업자의 손을 외부로 밀쳐내도록한 프레스의 작업 안전 장치에 관한 것이다.The present invention is fitted to the shank for attaching the upper mold of the various presses and by fixing the safety device on the other end the moment the upper mold comes down, the push rod is momentarily rotated to push the hand of the worker in the lower mold position to the outside The work safety device of the press.

종래에는 적외선, CDS 소자 및 광전자식등의 안전장치가 다수종 개발되고 등록되여 사용되고 있으나, 이들은 한결같이 장치의 복잡성으로 인하여 설치할때 프레스기의 손상을 입히고 전원이 없는 곳등에서는 실용성이 없었으며, 특히 광전자식이므로 프레스기의 작동이 진행중에 순간적인 정지 작동을 시킴으로 인하여 기계적인 무리를 반복, 되풀이되게 하므로서 조기마모 내지 파손의 결과를 초래하는 비경제적인 결점을 가져왔던 것이다.Conventionally, many types of safety devices such as infrared rays, CDS elements, and optoelectronics have been developed and registered, but they are inconsistent due to the complexity of the devices, which damages the press during installation, and have no practical use in places without power supply. Since it is a formula, the operation of the press machine causes an instantaneous stop operation, thereby causing the mechanical force to be repeated and repeated, resulting in an uneconomical defect that results in premature wear or breakage.

본 발명은 아와 같은 종래의 제결점을 근본적으로 해결 및 보완하고 고가의 프레스기를 분해, 조립 및 보울트 구멍하나의 손상도 입히지 않고 전원의 소용도 없도록 하기 위하여 장기간 동안 각종 실험과 연구를 거듭한 결과 소기의 목적을 달성할 수 있도록 개발한 것으로서 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.The present invention is a result of repeated experiments and studies for a long time in order to fundamentally solve and supplement the conventional defects such as ah, and to disassemble, assemble and damage the expensive press machine without damage to one bolt hole and use of power. As described in detail by the accompanying drawings as being developed to achieve the desired purpose is as follows.

프레스기(1)의 상부샹크(3)에 부착판넬(4)의 안내구(5)로 고정하고 부착판넬(4)타단의 지지홈(6)에는 작동봉(8)상부에 구성한 나선체(7)를 끼우되 상하에 너트(9)(9')로서 고정하며 작동봉(8) 하단은 스프링(13)을 끼운 관체(10)의 내경(11)에 내통되게 하며 관체(10)의 일측에 절취한 나선안내레인(12)로 안내되도록 로울러(15)를 보울트축(14)으로 작동봉(8)하단에 축설시킨다음 관체(10)하단에 일체로된 회전봉(10')은 지지관(18)에 베아링(19)(20)을 끼워서 회전봉(10')이 자유롭게 회전되게 하며, 밴드(16)에는 탄성판922)를 접속한 밀대(21)를 보울트(17)로 조여서 고정하였던 것이다.Spiral body 7 which is fixed to the upper shank 3 of the press 1 by the guide 5 of the mounting panel 4 and the support groove 6 on the other end of the mounting panel 4 is formed on the operating rod 8. ) And the upper and lower sides of the nut (9) (9 ') and fixed to the lower end of the operating rod (8) to the inner diameter (11) of the tubular body (10) with the spring (13) fitted on one side of the tubular body (10) The roller 15 is arranged under the operating rod 8 by the bolt shaft 14 so that the roller 15 is guided to the cut spiral guide lane 12, and the rotary rod 10 'integrated under the pipe 10 is supported by a support tube ( 18, the bearings 19 and 20 were inserted to allow the rotating rod 10 'to rotate freely, and the band 16 was fixed by tightening the rod 21 to which the elastic plate 922 was connected.

이와 같이된 본 발명의 작용효과를 설명하면 다음과 같다.Referring to the effects of the present invention as described above are as follows.

먼저 제1, 2도와 같이 조립한 다음 프레스기(1)의 상부샹크(3)에 부착판넬(4)의 안내구(5)로 조절하여 부착고정시키고 하단지지관(18)은 프레스기(1) 정반(2)의 일측 전방측면에 제3도 및 제4도와 같이 장치한다. 이때에 프레스기(1)와 상부샹크(3)와 정반(2)사이에 장치되는 상하부 금형과, 부착판넬(4)와 밀대(21)와의 간격 및 밀대(21)와 하부금형과의 간격등을 고려하여 장치한다.First, assembling as shown in Figs. 1 and 2, and then fixed to the upper shank (3) of the press machine (1) by adjusting the guide hole (5) of the attachment panel (4) and the lower support tube (18) One front side of (2) is mounted as shown in FIG. 3 and FIG. At this time, the upper and lower molds installed between the press machine 1, the upper shank 3 and the surface plate 2, the interval between the attachment panel 4 and the rod 21 and the distance between the rod 21 and the lower mold, etc. Consider the device.

이렇게 장치한 다음 작동할때는 상부샹크(3)가 내려올때에 부착판넬(4)도 상부샹크(3)에 고정 부착된 상태로 내려오며 타단의 지지홈(6)에 끼워진 나선체(7)가 너트(9)(9')로서 고정되어 있으므로 나선체(7)와 일체로된 작동봉(8)은 관체(10)의 내경(11)내로 눌려서 샹크(3)에 고정된 부착판넬(4)과 함께 내려 눌리게 된다. 이때에 작동봉(8) 하단에는 관체(10)가 90도 정도만 회전하도록 레일홈이 나선상으로 절개된 관체(10)일측의 안내레일(12)에 접속 구동되도록 보울트축(14)으로 로울러(15)가 축설되어 있기 때문에 관체(10)는 대략 90도 방향 회전하게 된다. 그러므로 관체(10)에 조여진 밴드(16)는 밀대(21)를 보울트(17)로 고정한 상태에 있기 때문에 제3도의 예시도와 같이 90도 회전한다.In this operation, when the upper shank (3) is lowered, the mounting panel (4) is also fixedly attached to the upper shank (3), and the spiral (7) inserted into the support groove (6) of the other end is nut. (9) (9 '), the working rod (8) integrated with the spiral body (7) is pressed into the inner diameter (11) of the tubular body (10) and the mounting panel (4) fixed to the shank (3). It is pressed down together. At this time, the roller (15) at the lower end of the operating rod (8) by the bolt shaft (14) to be connected to the guide rail (12) on one side of the pipe body (10) in which the rail groove is spirally cut so as to rotate only about 90 degrees (15) ), The tubular body 10 is rotated in approximately 90 degrees. Therefore, the band 16 fastened to the tubular body 10 rotates 90 degrees, as shown in FIG. 3, since the band 21 is in the state fixed with the bolt 17. FIG.

즉 제3도의 정반(2)위의 금형위치(A)지점위에 작업자의 손이 근접해 있는 상태에서 상부샹크(3)가 내려오면 밀대(21)은 밴드(16)로서 관체(10)에 고정되여 있다가 시계방향으로 90도 회전하는 순간 밀대(21)에 손을 보호하기 위해 부착한 탄성판(22)이 손을 밀쳐내게 되어 다치지 않게 된다. 관체(10)의 회전력은 안내레일(12)의 홈을 따라서 로울러(15)가 나선으로 굴러서 아래로 내려가게 되어 관체(10)만 90도 회전되며 이회전되는 관체(10)에 밴드(16)로서 고정된 밀대(21) 역시 회전하게 된다. 그리고 지지관(18)은 정반(2)위의 좌측에 안착된 상태로 지지하고 있고 지지관(18)의 내부에는 상하 베아링(19)(20)이 형성되어 있어서 관체(10)가 회전할때 끼워서 지지된 회전봉(10')의 회전이 용이하게 된다. 다시 말해서 부착판넬(4)이 상부샹크(3)가 내려눌릴때 눌려지면 작동봉(8)(작동봉은 내려 눌러주고 회전하지 않음) 역시 부착판넬(4)에 고정된체 수직으로 내려 불리면서 작동봉(8) 하단의 안내레일(12)홈을 통해서 축설된 로울러(15)가 관체(10)에 형성된 나선 안내레일(12)을 타고 내려가는데, 이때에 관체(10)의 안내레일(12)은 약간의 나선(90도 정도만)으로 홈이 형성되고 다음은 수직하향으로 형성된만큼 관체(10)는 90도 회전하게 된다. 그리고 상부샹크(3)가 상승하면서 고정된 부착판넬(4)도 상승하며 따라서 작동봉(8)은 관체(10)내에서 작동봉(8)을 탄지하고 있던 스프링(13)의 탄성으로 원위치하며, 작동봉(8) 하단의 로울러(15)는 다시 안내레일(12)을 따라서 수직으로 상승하면서 상부에서는 나선으로 안내되어 관체(10)는 시계 반대방향으로 90도 회전하여 원위치하고 다음 작동 준비단계에 있게 된다.That is, when the upper shank 3 descends while the operator's hand is close to the mold position A on the surface plate 2 of FIG. 3, the pusher 21 is fixed to the tubular body 10 as a band 16. While rotating clockwise 90 degrees, the elastic plate 22 attached to protect the hand to the pusher 21 is pushed out of the hand so as not to be injured. Rotation force of the tubular body 10 is the roller (15) rolls down the spiral along the groove of the guide rail 12 to descend down to the tubular body 10 is rotated 90 degrees and the band 16 to the tubular body 10 is rotated As the fixed rod 21 is also rotated. And the support tube 18 is supported in a state seated on the left side on the surface plate (2) and the upper and lower bearings (19, 20) are formed inside the support tube (18) when the tubular body (10) rotates Rotation of the rotating rod 10 'supported by the insertion is facilitated. In other words, if the mounting panel 4 is pressed when the upper shank 3 is pressed down, the operating rod 8 (the operating rod is pushed down and does not rotate) is also called vertically fixed to the mounting panel 4 and operated. The roller 15 laid down through the guide rail 12 groove at the bottom of the rod 8 descends on the spiral guide rail 12 formed in the tubular body 10, and at this time, the guide rail 12 of the tubular body 10. The groove is formed by a slight spiral (only about 90 degrees), and then the tubular body 10 rotates by 90 degrees as formed vertically downward. And as the upper shank 3 rises, the fixed mounting panel 4 also rises, so that the operating rod 8 is repositioned by the elasticity of the spring 13 holding the operating rod 8 in the tubular body 10. The roller 15 at the bottom of the operating rod 8 is again vertically along the guide rail 12 while being guided in a spiral at the top so that the tubular body 10 rotates 90 degrees counterclockwise to its original position and is ready for the next operation. Will be in.

이와 같이된 본 발명은 프레스기의 상부샹크 하단에 부착판넬로서 부착만 하면 정반 일측에 간단히 장치할 수 있고 하강 작동할때마다 하부금형 위치에 작업자의 손이 실수로 위치할 경우는 밀대가 순간적으로 밀어내게 되어 작업자가 손을 다치지 않게 되는 효과적인 것이다.The present invention as described above can be simply mounted on one side of the surface plate just attached to the bottom of the upper shank of the press machine, the pusher is pushed momentarily when the operator's hand accidentally located in the lower mold position every time the lower operation It is effective to prevent workers from hurting their hands.
