본 고안은 방전 가공기용 가공액 압력 가변 공급 장치에 관한 것으로 공작물 즉 철판의 두께에 따라 가공액의 토출 압력을 가변적으로 공급시켜 주므로서 상황에 따른 가공 작업이 효과적으로 됨에 주안점을 둔 것이다.The present invention relates to a variable processing pressure supply device for an electric discharge machine, the main focus is to effectively supply the discharge pressure of the processing liquid in accordance with the thickness of the workpiece, that is, the iron plate, effective processing according to the situation.

일반적으로 방전 가공기는 방전현상을 이용하여 고압의 전류로서 공작물을 가공하는 특수공작기게로서 주로 철판등의 구렁 및 절단 가공에 널리 쓰이는 것으로, 가공 전극(도시안됨)에 의한 1차 가공후의 가공부위에 칩(Chip)등을 제거함과 동시 매끄럽게 가공할 목적으로 가공액을 가공부위에 분출되게끔 한다.In general, the electric discharge machine is a special machine tool that processes workpieces with a high-pressure current by using discharge phenomena, and is mainly used for hollow and cut processing of steel plates, etc. The processing liquid is ejected to the processing part for the purpose of removing chips and processing smoothly at the same time.

따라서, 공작물의 두께 및 가공속도에 따라 가공액의 분출 압력의 가변성을 필요로 한다.Therefore, it requires the variability of the ejection pressure of the processing liquid according to the thickness and the processing speed of the workpiece.

그런데, 종래에는 고압만으로 가공되어 가공액의 공작물 두께에 따른 가변압력 조절이 되지 않아 즉, 얇은 공작물의 가공시 가공전극의 흔들림이 발생되어 정확한 치수의 공작물을 얻기가 불가능한 것이었다.However, in the related art, it is impossible to obtain a workpiece having a precise dimension because it is processed only at a high pressure and does not control the variable pressure according to the workpiece thickness of the processing liquid.

따라서 본 고안은 이상과 같은 문제점을 해결하고자 일측에 송출공의 조절을 위한 니들밸브와 다른 일측에 유입공을 조절하기 위한 솔레노이드밸브에 의한 공기압 작동에 따라 작동되는 피스톤 밸브로 구성되어 공작물의 두께에 따라 가공액의 송출압력을 가변토록 하여 보다 효과적인 방전가공이 이루어지도록 안출된 것으로서, 이하에서 첨부도면에 의해 상세히 설명하면 다음과 같다.Therefore, the present invention is composed of a needle valve for adjusting the discharge hole on one side and a piston valve operated by pneumatic operation by the solenoid valve for adjusting the inlet hole on the other side to solve the problems as described above. Accordingly, the discharge pressure of the processing liquid is varied so as to make the discharge processing more effective, which will be described in detail below with reference to the accompanying drawings.

One side of the body (1) consisting of (15) is inserted into the valve case 21 is inserted and installed in the transfer passage 15 side of the delivery chamber 14 by the needle valve (2), the other side of the solenoid A tapered piston valve (4) having a through hole (41) is inserted into the cylinder (42) and the cylinder cap (43) by a valve (3) having a through hole (41) at the end of the transfer passage (15) in the inflow chamber (13). As shown in the figure, reference numerals 31 and 32 in the drawings are air supply plates 20, 210, 40, 420, and 430 are packing members, P 1 processing liquid delivery pump, and P 2 are air delivery pumps.

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

첨부된 도면의 상태는 저압가공상태로서 공작물의 두께가 얇을시 콘튜럴장치(도시안됨)에 의해 솔레노이드 밸브(3)가 에어공급판(32)을 막아준 상태로 에어공급관(31)으로 공기가 유입되어 피스톤 밸브(4)는 이송통로(15)를 막아준 상태로서, 펌프(P1)의 작동으로 가공액이 몸체(1)의 유입공(11)과 유입실(13) 및 피스톤 밸브(4)의 통공(41)을 걸쳐 이송통로(15)와 밸브케이스(21)이 송출실(14) 및 송출공(12)을 통하여서 저압으로 가공액이 분출되어지며, 고압가공시 즉, 공작물의 두께가 두꺼울시에는 솔레노이드 밸브(3)가 에어공급판(31)을 막아준 상태로 에어 공급판(32)으로 공기가 유입되어 피스톤 밸브(4)는 좌측으로 이동되어 이송통로(15)를 개방시킨 상태로 유입공(11)으로 유입된 각공엑이 높은 압력으로 송출되는데, 이때 니들밸브(2)에 의해 가공액 양이 조절된다.The state of the accompanying drawings is a low pressure processing state, when the thickness of the workpiece is thin, air is supplied to the air supply pipe 31 with the solenoid valve 3 blocking the air supply plate 32 by the control device (not shown).
