It is used to maintain the inside of the main cylinder at a predetermined pressure to perform smoothly, the conventional one is relatively complicated in structure to allow the main piston to operate in accordance with the rising to the position for pressing the upper body, the lower body In addition, the cost was not only high, but also in proportion to the complicated structure, there were many concerns about failure, and thus there was a problem in that the interlocking with the main piston was insufficient, so that the water valve could not function as a full-water valve.

본 고안은 이와 같은 종래것이 문제점을 해결한 것인바, 본 고안은 구조가 간단하여 비용이 저렴하고, 고장의 우려가 작을 뿐 아니라 메인 피스턴과의 연동작용이 원활한 유압프레스의 만수변 밸브장치를 제공하는데 그 목적이 있다.The present invention solves the problems of the prior art, the present invention provides a low-pressure valve full-water valve device of a hydraulic press that is simple in structure, low cost, low risk of failure and smooth interlocking action with the main piston.

A boss 26 having an annular recess 25 is protruded, and a hole 27 into which the rod portion of the valve 21 is fitted is drilled in the center of the boss 26 and the flange 20. Between the divided flow passages 24a and 24b, there is formed a pressurized flow passage 28 as shown by a dotted line in FIG. 2 and a solid line in FIG.

밸브(21)는 상기 플랜지(20)의 밸브시이트(23)와 접하면서 분할형유로(24 a)(24b)를 개폐시켜주는 헤드(29)와 상기 구멍(27)을 통하여 보스(26) 밖으로 연장되는 로드(30)를 가지고 있다.The valve 21 is in contact with the valve seat 23 of the flange 20 and out of the boss 26 through the head 29 and the hole 27 that open and close the divided flow passages 24 a and 24 b. It has a rod 30 that extends.

플랜지(20)의 보스(26) 밖으로 노출되는 로드(30)에는 환상의 요입부(31)를 가진 피스턴(32)이 끼워져 있으며, 이 피스턴(32)를 한쪽끝부분이 보스(26)의 요입부 (25)에, 다른 한쪽 끝부분이 피스턴(32)의 요입부(31)에 각각 지지되는 코일 압측스프링(33)으로 탄성되어 있고, 이 피스턴(32)은 로드(30)의 끝부분과 체결되는 너트(3 4)로 지지되어 있다.The rod 30 exposed out of the boss 26 of the flange 20 is fitted with a piston 32 having an annular recess 31, and one end of the piston 32 has a yaw of the boss 26. At the mouth 25, the other end is elastically coiled spring 33 which is supported by the recess 31 of the piston 32, and this piston 32 is connected to the end of the rod 30. It is supported by a nut (34) to be fastened.

실린더(22)는 상기 피스턴(32)이 끼워질 수 있는 내경을 갖고 있으며, 상기 플랜지(20)의 분할형유로(24a)(24b)를 막지않는 범위내의 외경을 가진 것으로서, 상기 플랜지(20)와 세트스크류(35)로 조립되어 있다.The cylinder 22 has an inner diameter into which the piston 32 can be fitted, and has an outer diameter within a range of not blocking the divided flow passages 24a and 24b of the flange 20, and the flange 20 And a set screw 35 are assembled.

이 실린더(22)는 상기 플랜지(20)의 분할형유로(24a)(24b) 사이에 형성된 가압유로(28)와 연통하는 가압유로(36)를 가지고 있으며, 이 가압유로(36)의 출구(37)는 실린더(22)의 일측 끝부분에 형성되어 있고, 또 실린더(22)의 다른 일측 끝부분에는 상기 피스턴(32)과 플랜지(20)사이에 있는 오일이 배출되는 구멍(38)이 천공되어 있다.The cylinder 22 has a pressurizing passage 36 in communication with a pressurizing passage 28 formed between the divided flow passages 24a and 24b of the flange 20, and the outlet of the pressurizing passage 36 37 is formed at one end of the cylinder 22, and at the other end of the cylinder 22, a hole 38 through which oil is discharged between the piston 32 and the flange 20 is drilled.

도면중 미설명부호 39는 니플, 40은 필터용플랜지, 41은 가압 오일관, 42는 피스턴링이다.In the drawings, reference numeral 39 denotes a nipple, 40 denotes a filter flange, 41 denotes a pressurized oil pipe, and 42 denotes a piston ring.

이와 같이 구성된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention configured as described above are as follows.

본 고안은 제1도에서 메인오일유입관(14)을 통해 오일을 공급하여 메인 피스턴 (13)을 상, 하부몸체(11)(12)를 가압시켜주기 위한 위치로 상승시켜줄때 메인오일유입관(14)과 연결된 가압오일관(14)으로 가압용오일 공급되므로 제3도에 예시도 나와같이 오일이 플랜지(20)의 가압유로(28)를 지나 실린더(22)의 가압유로(36)와 출구(37)를 통해 실린더(22)내로 유입된다. 따라서 실린더(22)에 있던 피스턴(32)은 압축코일 스프링(33)을 압축시켜주면서 밸브(21)를 쇄신도시처럼 밀어주므로 압축 코일스프링(33)의 탄성에 의해 플랜지(20)의 밸브시이트(23)와 접하면서 분할형유로( 24a), (24b)를 폐쇄하고 있던 밸브(21)의 헤드(29)가 밸브시이트(23)로부터 분리되면서 분할형유로(24a), (24b)를 개방시켜준다. 그러므로 도시가 생략된 오일탱크로부터 진공상태로 되는 유압프레스의 메인 실린더(16)내로 만수용 오일이 공급되므로 메인피스턴(13)이 상, 하부몸체(11)(12)를 가압시켜주기 위하여 상승운동을 계속하더라도 이 상승운동을 원활하게 이루어지도록 해 준다.The present invention is to supply the oil through the main oil inlet pipe 14 in Figure 1 when raising the main piston 13 to the position for pressurizing the upper body, lower body 11, 12 main oil inlet pipe Since the pressurized oil is supplied to the pressurized oil pipe 14 connected to the oil 14, the oil passes through the pressurized oil passage 28 of the flange 20 and the pressurized oil passage 36 of the cylinder 22 as shown in FIG. It enters the cylinder 22 through the outlet 37. Therefore, the piston 32 in the cylinder 22 compresses the compression coil spring 33 and pushes the valve 21 as shown in the figure, so that the valve seat of the flange 20 may be caused by the elasticity of the compression coil spring 33. While the head 29 of the valve 21 closing the divided flow passages 24a and 24b while being in contact with 23 is separated from the valve seat 23, the divided flow passages 24a and 24b are opened. give. Therefore, since the water for full water is supplied from the oil tank (not shown) into the main cylinder 16 of the hydraulic press to be in a vacuum state, the main piston 13 moves upward to pressurize the upper and lower bodies 11 and 12. Even if you continue, this ascending movement will be smooth.

상기 분할형유로(24a), (24b)를 통해 만수용 오일이 공급되는 상태가 제4도에 잘 표현되어 있다.The state in which the water for full water is supplied through the divided flow passages 24a and 24b is well represented in FIG.

상술한 바와 같은 가압 고정을 실시한 후 상, 하부몸체(11)(12)로부터 가공물을 꺼내기 위하여 즉 상,하부몸체(11)(12)를 본래의 위치로 환원시켜주기 위하여 메인실린더(16)내의 오일을 배출시켜 메인 피스턴(13)을 하강시켜줄때, 메인실린더(16)내의 오일이 배출됨과 동시에 제5도에 예시한 바와 같이 가압오일관(41)과 연결된 플랜지( 20)의 가압유로(28)와 실린더(22)의 가압유로(36)를 통해서 실린더(22)내의 가압용 오일이 배출되어 밸브(21)가 압축코일스프링(33)의 탄성에 의해서 플랜지(20)의 밸브시이트(23)와 다시 접하게 되어 분할형유로 (24a), (24b)를 폐쇄시켜준다. 이때 밸브(21)가 닫히면서 피스턴(32)과 플랜지(20) 사이로 유입되는 오일은 실린더(22)의 구멍(38)으로 배출되어 피스턴(32)의 계속되는 작동이 원활하게 이루어지도록 해준다.After the pressure fixing as described above, in order to remove the workpiece from the upper and lower bodies 11 and 12, that is, to reduce the upper and lower bodies 11 and 12 to their original positions, When the oil is discharged and the main piston 13 is lowered, the oil in the main cylinder 16 is discharged and at the same time, the pressurized flow path 28 of the flange 20 connected to the pressurized oil pipe 41 as illustrated in FIG. The pressure oil in the cylinder 22 is discharged through the pressure passage 36 of the cylinder 22 and the valve 21 of the valve seat 23 of the flange 20 is caused by the elasticity of the compression coil spring 33. And closes the divided flow passages 24a and 24b. At this time, the oil flowing between the piston 32 and the flange 20 while the valve 21 is closed is discharged into the hole 38 of the cylinder 22 to facilitate the continuous operation of the piston 32.

상술한 바와 같은 본 고안은 종래것과 비교하여 구조가 간단하며, 비용이 저렴하고, 고장의 우려가 적을 뿐 아니라 메인피스턴(13)과의 연동작용이 원활하다. 즉 메인피스턴(13)의 운동에 따른 메인실린더(16)내의 압력 변화를 별도의 감지수단을 이용하지 않고서도 상기 압력변화를 즉시 보상하여 주기 때문에 메인피스턴( 13)의 작동에 필요한 오일의 압력을 낮추면서도 상, 하부몸체(11)(12)를 가압시켜 줄 수 있을 뿐 아니라 메인피스턴(13)의 작동 속도 또한 증가시켜줄 수 있는 것이어서 프레스의 생산성과 조업효율을 높여줄 수 있는 장점이 있다.The present invention as described above has a simpler structure, lower cost, less risk of failure as well as smoother interlocking action with the main piston 13 as compared with the conventional one. That is, the pressure change in the main cylinder 16 according to the movement of the main piston 13 is compensated immediately without using a separate sensing means, so that the pressure of the oil required for the operation of the main piston 13 is increased. While lowering, the lower body (11) (12) can not only pressurize, but also increase the operating speed of the main piston (13) has the advantage of increasing the productivity and operating efficiency of the press.
