이상 설명한 바와 같은 본 발명에 따르면,According to the present invention as described above,

고온으로 가열된 시험편에 냉각수를 분사하여 급속 냉각시키는 시험이 가능해짐으로써 보다 다양한 조건의 시험이 가능해졌다.By allowing the cooling water to be rapidly cooled by injecting coolant into the test piece heated to a high temperature, it is possible to test a wider range of conditions.

한편, 본 발명은 단열챔버에 드레인관이 설치되고, 또한 단열챔버의 내부에 냉각수받침대가 구비됨으로써 시험중 분사되는 냉각수를 시험 종료후 단열챔버로부터 제거하기가 매우 용이해진다.On the other hand, according to the present invention, the drain pipe is installed in the adiabatic chamber, and the cooling water support is provided inside the adiabatic chamber, so that the coolant injected during the test can be easily removed from the adiabatic chamber after the test.

따라서, 잔류 냉각수에 의한 장비의 손상을 방지하고, 안정성을 유지하며, 다음 시험까지의 준비시간을 단축시킬 수 있게 되는 효과가 있다.Therefore, there is an effect that it is possible to prevent damage to the equipment by the residual coolant, maintain stability, and shorten the preparation time until the next test.

이하, 본 발명을 첨부된 예시도면을 참조하여 상세히 설명한다.Hereinafter, with reference to the accompanying drawings, the present invention will be described in detail.

도 1은 본 발명에 따른 열간 가공 시험장치의 구성도로서, 본 발명은 외부와 차단된 내부공간을 형성하는 단열챔버(10)와, 상기 단열챔버(10)의 양측부를 관통하여 설치된 유압실린더(20)와, 상기 유압실린더(20)에 장착된 지그홀더(30)와, 상기 지그홀더(30)에 장착된 지그프레임(40)과, 상기 지그프레임(40)에 구비된 지그 블럭(50)과, 상기 지그블럭(50)에 전력을 공급하는 전원공급장치(100)와, 상기 단열챔버(10)에 진공을 형성하는 진공펌프(200) 및 상기 단열챔버(10)의 내부에 설치된 냉각수관(320)에 연결되어 냉각수탱크(300)의 냉각수를 상기 지그블럭(50)에 의해 고정된 시험편(1)으로 공급하는 냉각수펌프(310)를 포함한다.1 is a configuration diagram of a hot working test apparatus according to the present invention, the present invention is a heat insulating chamber 10 to form an internal space blocked from the outside, and a hydraulic cylinder installed through both sides of the heat insulating chamber 10 ( 20), a jig holder 30 mounted on the hydraulic cylinder 20, a jig frame 40 mounted on the jig holder 30, and a jig block 50 provided on the jig frame 40. And, the power supply device 100 for supplying power to the jig block 50, the vacuum pump 200 for forming a vacuum in the heat insulating chamber 10 and the cooling water pipe installed in the heat insulating chamber 10 It is connected to the 320 includes a cooling water pump 310 for supplying the cooling water of the cooling water tank 300 to the test piece (1) fixed by the jig block 50.

상기 유압실린더(20), 지그홀더(30), 지그프레임(40) 및 지그블럭(50)은 상기 단열챔버(10)의 양쪽에 상호 마주보는 대칭 구조로 설치된다.The hydraulic cylinder 20, the jig holder 30, the jig frame 40 and the jig block 50 are installed in a symmetrical structure facing each other on both sides of the heat insulating chamber (10).

따라서, 상기 지그블럭(50)에 시험편(1)을 고정하고, 상기 유압실린더(20)를 작동시켜 시험편(1)의 열간 가공 시험을 실시할 수 있다.Therefore, the test piece 1 may be fixed to the jig block 50, and the hydraulic cylinder 20 may be operated to perform a hot working test of the test piece 1.

상기 유압실린더(20)의 실린더로드(21)에 지그홀더(30)가 볼트로 장착된다.The jig holder 30 is mounted to the cylinder rod 21 of the hydraulic cylinder 20 by bolts.

상기 지그홀더(30)의 단부에도 상기 지그프레임(40)이 일체로 장착된다.The jig frame 40 is integrally mounted to an end of the jig holder 30.

상기 지그프레임(40)에는 상기 지그블럭(50)이 착탈될 수 있으며, 지그홀더(30)의 내부공간에 구비되는 지그블럭고정대(60)와 스페이서(70)에 의해 상기 지그블럭(50)이 지지된다.The jig block 50 may be attached to or detached from the jig frame 40, and the jig block 50 is formed by the jig block fixing unit 60 and the spacer 70 provided in the internal space of the jig holder 30. Supported.

상기 전원공급장치(100)는 전력공급선(110)으로 양쪽 지그블럭(50)에 연결된다.The power supply device 100 is connected to both jig blocks 50 by a power supply line 110.

따라서, 전력을 공급하면 상기 지그블럭(50)을 통해 시험편(1)에 전류가 통하므로 시험편(1)의 재질에 따른 저항열이 발생하여 승온이 이루어진다.Therefore, when power is supplied, a current flows through the jig block 50 to the test piece 1, so that resistance heat according to the material of the test piece 1 is generated, thereby raising the temperature.

그 외, 화염에 의한 직접 가열 방식이나 유도전류를 이용한 유도 가열 방식을 적용할 수 있음은 물론이다.In addition, it is a matter of course that a direct heating method using a flame or an induction heating method using an induction current can be applied.

상기 진공펌프(200)는 상기 단열챔버(10)와 호스 또는 파이프로 연결되어 있 으며, 상기 호스 또는 파이프에는 쓰리웨이밸브(210)가 설치된다.The vacuum pump 200 is connected to the adiabatic chamber 10 by a hose or pipe, and the three-way valve 210 is installed in the hose or pipe.

따라서, 진공펌프(200) 작동시에는 상기 쓰리웨이밸브(210)를 열어 단열챔버(10)의 내부의 공기를 진공펌프(200)로 빨아 들여 진공을 형성하고, 진공펌프(200) 정지시에는 상기 쓰리웨이밸브(210)를 닫아 단열챔버(10) 내부의 진공을 유지한다.Therefore, when the vacuum pump 200 is operated, the three-way valve 210 is opened to suck the air in the adiabatic chamber 10 into the vacuum pump 200 to form a vacuum, and when the vacuum pump 200 is stopped. The three-way valve 210 is closed to maintain the vacuum inside the adiabatic chamber 10.

또한, 단열챔버(10) 내부의 진공을 해제할때는 상기 쓰리웨이밸브(210)를 대기중으로 개방하여 단열챔버(10) 내부로 대기를 유입시킴으로써 진공을 해제한다.In addition, when releasing the vacuum in the adiabatic chamber 10, the three-way valve 210 is opened to the atmosphere to release the vacuum by introducing the atmosphere into the adiabatic chamber 10.

상기와 같이 시험편(1)의 고온 가열시 진공 분위기를 형성하는 것은, 금속재료가 대기중에 노출되어 있으면 재료의 표면에서 산화 및 환원반응이 발생하여 재료의 물성에 영향을 받고, 고온에서는 그러한 반응이 더욱 활발히 이루어지기 때문에, 상기 시험편(1)에 고온시 대기와의 접촉에 의한 영향을 최소화하기 위한 것이다.As described above, the formation of a vacuum atmosphere during the high temperature heating of the test piece 1 causes oxidation and reduction reactions on the surface of the material when the metal material is exposed to the air, thereby affecting the physical properties of the material. Since it is made more actively, it is to minimize the effect of contact with the atmosphere at high temperature in the test piece (1).

한편, 상기 냉각수펌프(310)는 상기 단열챔버(10)의 외부에 설치된다. 통상 냉각수가 저장된 상기 냉각수탱크(300)에 인접하여 설치된다.On the other hand, the cooling water pump 310 is installed outside the insulated chamber (10). Usually, the coolant is installed adjacent to the coolant tank 300 stored therein.

상기 냉각수펌프(310)는 호스 또는 관으로 단열챔버(10)에 관통 상태로 설치된 커넥터(315)에 연결된다.The cooling water pump 310 is connected to the connector 315 installed in a penetrating state to the insulated chamber 10 by a hose or pipe.

상기 커넥터(315)의 단열챔버(10) 안쪽 단부에는 상기 냉각수관(320)이 연결되는데, 상기 냉각수관(320)은 금속재질의 주름관으로서 자유로이 변형 및 변형된 상태를 유지하는 것이 가능하다.The cooling water pipe 320 is connected to an inner end of the heat insulating chamber 10 of the connector 315, and the cooling water pipe 320 may be freely deformed and deformed as a corrugated pipe made of metal.

즉, 상기 냉각수관(320)의 단부에 냉각수의 효율적 분사를 위해 냉각수노 즐(330)이 구비되는데, 상기 냉각수노즐(330)을 냉각수 분사방향이 상기 시험편(1)을 향하도록 적절히 위치시키기 위해 상기 냉각수관(320)을 적절히 휨변형시킬 수 있고, 변형시킨 후에 냉각수관(320)은 그 변형 상태를 유지하도록 되어 있다.That is, a coolant nozzle 330 is provided at the end of the coolant pipe 320 for efficient spraying of the coolant, and the coolant nozzle 330 is appropriately positioned so that the coolant spray direction is directed toward the test piece 1. The coolant pipe 320 can be deflected appropriately, and after being deformed, the coolant pipe 320 maintains its deformation state.

이상 설명한 구성에 의하여 본 발명은 통상적인 시험편의 가열 과정 후에, 시험편(1)에 냉각수를 토출하여 냉각수에 의한 시험편 급냉 조작을 실시할 수 있게 된다.According to the above-described configuration, the present invention enables the test piece quenching operation by the coolant to be discharged by discharging the coolant to the test piece 1 after the heating process of the normal test piece.

상기 냉각수에 의한 시험편의 급냉은 시험편의 사이즈에 따라 -200℃/sec에서 최대 -400℃/sec까지 가능하므로 시험편을 고온상태에서 급속냉각시킴으로써 고온상태에서의 결정립 사이즈를 확인할 수 있게 된다.(종래 가스젯 방식의 냉각방식에서는 냉각속도가 -20℃/sec에서 최대 -50℃/sec 정도여서 고온 시험편 냉각시 변태와 석출 거동이 발생할 수 있으므로 원상태의 물성을 확인하기 곤란하였다.)Rapid cooling of the test piece by the cooling water is possible from -200 ° C / sec up to -400 ° C / sec depending on the size of the test piece, thereby rapidly cooling the test piece in a high temperature state, so that the grain size in the high temperature state can be confirmed. In the gas jet type cooling method, the cooling rate is -20 ° C / sec up to about -50 ° C / sec. Therefore, it is difficult to check the properties of the original state because transformation and precipitation behavior may occur when cooling the hot specimen.)

한편, 상기와 같이 냉각수를 시험편(1)으로 분사할 수 있게 됨으로써 냉각수를 이용한 시험편 급냉이 가능해졌으나, 시험을 위해 단열챔버(10) 내로 공급된 냉각수의 사후 처리가 문제였다.On the other hand, by allowing the cooling water to be injected into the test piece 1 as described above, it was possible to quench the test piece using the cooling water, but the post treatment of the cooling water supplied into the adiabatic chamber 10 for the test was a problem.

따라서, 본 발명은 도 2에 도시된 바와 같이, 상기 단열챔버(10)의 하면 일측에 드레인관(11)을 설치하고, 상기 드레인관(11)에 개폐밸브(12)를 설치하였다.Therefore, in the present invention, as shown in Figure 2, the drain pipe 11 is provided on one side of the lower surface of the heat insulating chamber 10, the on-off valve 12 is provided in the drain pipe (11).

따라서, 시험 종료후(진공 해제 상태), 상기 개폐밸브(12)를 열어 드레인관(11)을 개방함으로써 단열챔버(10)의 하부에 고여 있던 냉각수가 드레인관(11)을 통해 외부로 배출될 수 있도록 하였다.Therefore, after completion of the test (vacuum release state), the open / close valve 12 is opened to open the drain pipe 11 so that the coolant accumulated in the lower portion of the adiabatic chamber 10 can be discharged to the outside through the drain pipe 11. To make it possible.

상기와 같이 하면 드레인관(11)을 통한 냉각수 배출이 종료된 뒤, 단열챔 버(10)의 도어(별도로 도시하지 않음, 열간 가공 시험장치에서 시험편(1)의 설치 및 회수를 위해 단열챔버의 도어는 반드시 구비된다.)를 열고 바닥면의 잔여 물기를 닦아 내면 추후, 시험을 다시 진행할 수 있다.(물기를 제대로 제거하지 않으면 다른 시험을 위해 진공을 형성할 때 물방울이 사방으로 튀어 내부 관찰이 어렵고, 튀는 물방울이 장치 내부의 구석으로 침투하여 추후 제거가 용이하지 않다.)In this case, after the discharge of the coolant through the drain pipe 11 is finished, the door of the thermal insulation chamber 10 (not shown separately) of the thermal insulation chamber for installation and recovery of the test piece 1 in the hot working test apparatus. Open the door, and wipe off any remaining water on the bottom, so that you can resume the test later. (If you do not remove the water properly, the water droplets will splash in all directions when you create a vacuum for another test. Difficult, splashing water droplets penetrate into corners inside the device and are not easy to remove later.)

한편, 도 3에 도시된 바와 같이, 상기 단열챔버(10)의 바닥에 냉각수받침대(400)를 설치할 수 있다.On the other hand, as shown in Figure 3, the cooling water support 400 may be installed on the bottom of the insulated chamber (10).

상기 냉각수받침대(400)는 바닥면이 상기 드레인관(110) 설치 위치를 향해 경사 형성되어 있고, 상기 드레인관(110)과 마주보는 지점에 드레인관(110)의 입구와 일치하는 배출공(410)이 형성된다.The cooling water support 400 has a bottom surface inclined toward the installation position of the drain pipe 110, the discharge hole 410 corresponding to the inlet of the drain pipe 110 at the point facing the drain pipe 110 ) Is formed.

따라서, 시험편(1)으로 분사된 냉각수는 모두 상기 냉각수받침대(400)로 떨어져 모이게 되고, 냉각수받침대(400)의 냉각수는 경사진 바닥면을 따라 배출공(410)쪽으로 흘러서, 상기 드레인관(110)을 통해 배출될 수 있다.Therefore, all of the coolant injected into the test piece 1 is separated by the coolant support 400, and the coolant of the coolant support 400 flows toward the discharge hole 410 along the inclined bottom surface, and the drain pipe 110. Can be discharged through).

따라서, 드레인관(110)을 통한 냉각수 배출이 끝난 뒤, 도어를 열고 단열챔버(10)에서 상기 냉각수받침대(400)를 꺼내어 물기를 닦으면 물기를 완전하게 제거하기가 더욱 용이해진다.Therefore, after the discharge of the cooling water through the drain pipe 110 is finished, opening the door and taking out the cooling water support 400 from the adiabatic chamber 10 makes it easier to completely remove the water.

한편, 상기 냉각수받침대(400)의 테두리 부분에는 열에 강한 내열성 고무재질로 이루어진 시일부재(420)가 구비된다.On the other hand, the edge portion of the cooling water support 400 is provided with a sealing member 420 made of a heat resistant rubber material resistant to heat.

따라서, 냉각수받침대(400) 설치 상태에서 냉각수가 단열챔버(10) 벽면과 냉각수받침대(400)의 테두리 부 사이로 침투되어 단열챔버(10)의 바닥면으로 흘러드 는 것을 방지해준다.Therefore, in the coolant support 400 installed state, the coolant penetrates between the wall surface of the heat insulation chamber 10 and the edge of the coolant support 400 to prevent the coolant from flowing to the bottom surface of the heat insulation chamber 10.

따라서, 시험 종료후 상기 냉각수받침대(400)의 물기만 제거하면 되고, 단열챔버(10)의 바닥면은 물기를 닦아낼 필요가 없게 되어 물기 제거 작업이 보다 용이해진다.Therefore, it is only necessary to remove the water of the cooling water support 400 after the end of the test, and the bottom surface of the thermal insulation chamber 10 does not need to wipe off the water, thereby making the water removal work easier.

상기와 같이 단열챔버(10) 내부의 잔류 냉각수를 완전하게 제거하기 용이함으로써 잔류 냉각수에 의해 단열챔버(10) 내부의 장비들이 부식되거나 전자 및 전기 제품에 누수에 의한 오작동을 유발하지 않으므로 장비의 안정성이 향상된다.As described above, it is easy to completely remove the residual coolant inside the insulation chamber 10, so that the equipment inside the insulation chamber 10 is not corroded by the residual coolant or causes malfunction by leakage of electronic and electrical products. This is improved.

또한, 보다 신속하게 잔류 냉각수를 제거할 수 있으므로 다음 시험까지의 준비 시간이 단축되어 보다 많은 시험을 실시할 수 있게 되는 장점이 있다.In addition, since the remaining coolant can be removed more quickly, the preparation time until the next test can be shortened, and thus more tests can be performed.
