본 고안은 유압 폐회로방식의 유압식 다이쿠션장치에 관한 것이다. 종래에 다이쿠션장치로 사용되어 왔던 공압식 다이쿠션은 용량이 비교적 적은데비해 외형은 상당히 컸기 때문에 제작 설비비용도 상당히 많이 들었을 뿐만아니라 취급에 있어서도 매우 불편하였다.The present invention relates to a hydraulic die-cushioning device of a closed hydraulic system. The pneumatic die cushion, which has been conventionally used as a die cushioning device, has a relatively small capacity and a large appearance, and therefore, a large amount of manufacturing equipment costs are required, and handling is very inconvenient.

본 고안은 상기한 바와같은 단점을 제거하기 위하여 안출된 것으로 작은 외형으로도 큰 용량을 낼 수 있어 취급이 간편하게 되는 폐회로식 유압다이쿠션장치를 제공하는 것이 그 목적이다.It is an object of the present invention to provide a closed-loop hydraulic die cushioning device which is devised to eliminate the drawbacks as described above, which can produce a large capacity even with a small appearance, thereby simplifying handling.

본 고안은 하부에는 흡입밸브(9)와 기름배출 조절밸브(10)를 내장하며 상부에는 피스톤 세트(6)가 피스톤 세트 귀환스프링(7)으로 지지되어 보울트(3)로 체결된 플랜지(2)에 의해 갇혀있도록 내장되어 있는 실린더(8)가 기름냉각용 냉각수코일(5)이 내장되어 있는 바깥케이스(4)와 체결되어 구성되는 것이다.According to the present invention, the lower part has a suction valve (9) and an oil discharge control valve (10), and a piston set (6) is supported by a piston set return spring (7) and a flange (2) fastened by a bolt (3). The cylinder (8), which is embedded to be trapped by, is coupled to the outer case (4) in which the oil cooling coolant coil (5) is incorporated.

본 고안을 도면에 예시된 일실시예를 참고하여 상세히 설명하면 다음과 같다.Referring to the present invention in detail with reference to an embodiment illustrated in the drawings as follows.

본 고안에 따른 장치를 구성하는 실린더(8)의 상부에 위치하는 피스톤세트(6)와 밀착되어 있으며 외부로 돌출되어 있는 밀대(1)가 프레스기계등의 슬라이드램(14)에 의해 하강운동을 하게되면 피스톤세트(6)는 피스톤세트 귀환스프링(7)을 압축시키면서 하강하게 된다. 이때 실린더(8) 내부에 있는 기름은 압력상승으로 인하여 기름배출조절밸브(10)의 스프링(11)을 밀면서 배출되어 바깥케이스내부로 흘러들어간다. 기름배출조절밸브(10)의 스피링(11)력은 외부에 설치되어 있는 핸들(13)의 스크류(12)를 회전시켜서 조절할 수 있으므로 실린더(8)의 내압 한도를 조절할 수 있어 용량조절도 가능하게 된다.The push rod 1 which is in close contact with the piston set 6 located on the upper part of the cylinder 8 constituting the device according to the present invention and protrudes outwards is moved by a slide ram 14 such as a press machine. The piston set 6 is lowered while compressing the piston set return spring 7. At this time, the oil in the cylinder 8 is discharged while pushing the spring 11 of the oil discharge control valve 10 due to the pressure rises and flows into the outer case. The spring (11) force of the oil discharge control valve (10) can be adjusted by rotating the screw (12) of the handle (13) installed on the outside, so that the pressure limit of the cylinder (8) can be adjusted to adjust the capacity. Done.

한편 피스톤세트(6)가 완전하강하여 피스톤세트 귀환스프링(7)의 탄발력으로 다시 상승하게 되면 실린더(8) 내부에는 흡입력이 발생하게 되어 흡입밸브(9)를 통해 바깥케이스(4)의 내부로부터 기름을 흡입하게 된다.On the other hand, when the piston set 6 is completely lowered and rises again due to the repulsive force of the piston set return spring 7, the suction force is generated inside the cylinder 8 and the inside of the outer case 4 through the suction valve 9. Inhaling oil from the

상기와 같은 과정이 반복되어 동작되어 폐회로를 이루게되므로 동작에 따른 기름손실없이 정확하게 작용하게 되며 작동시에 기름에서 발생한 열은 바깥케이스(4)에 내장되어 있는 냉각수코일(5)에 의해 냉각되도록 되어 있다.As the above process is repeated to form a closed circuit, it operates accurately without oil loss according to the operation, and heat generated from the oil during operation is cooled by the cooling water coil 5 embedded in the outer case 4. have.

이상 설명된 바와같이 본 고안은 유압을 이용한 폐회로 방식을 채택하고 있으므로 별도의 기름공급이 필요없으며 비교적 적은 크기의 실린더를 대용량의 힘을 낼 수 있어 소형제작이 용이하게 되며 취급이 간단하여 프레스등의 기계에 부착하기 쉽게 되어 있다.As described above, the present invention adopts a closed-circuit method using hydraulic pressure, so no oil supply is required, and a relatively small sized cylinder can exert a large capacity, making it easy to manufacture small and simple to handle. Easy to attach to machine
