Description
본 고안은 열처리된 제품의 변형을 방지하여 품질을 향상시키고 피가공물을 연속적으로 냉각함으로써 생산성을 증진시킬 수 있도록 된 열처리용 냉각장치에 관한 것이다.The present invention relates to a cooling apparatus for heat treatment that is capable of improving the quality by preventing deformation of the heat treated product and improving productivity by continuously cooling the workpiece.
종래에는 고온으로 가열된 원형톱 등의 납작한 제품을 냉각하기 위해서는 제품을 메쉬벨트 등의 이송장치를 이용하여 연속가열로에 통과시켜 고온으로 열처리를 한 후, 이 열처리된 제품을 그 내부에 냉각수가 마련된 냉각조 등에 자유낙하시켜서 냉각하거나, 열처리된 제품을 소정 형태의 지그로 체결하여 냉각조 등에 담가서 냉각하였다.Conventionally, in order to cool flat products such as circular saws heated to a high temperature, the products are passed through a continuous heating furnace using a conveying device such as a mesh belt and heat treated at a high temperature. The product was cooled by dropping freely in a cooling tank or the like, or by fastening the heat-treated product with a jig of a predetermined form and immersing in a cooling tank.
그런데, 상기 자유낙하에 의한 냉각방법은 열처리된 고온의 제품을 냉각조의 냉각수에 급속도로 낙하시키는 관계로 이에 따른 충격이나 급속냉각 등에 의해 제품의 변형이 일어나므로 품질이 저하될 뿐만 아니라, 열처리된 제품을 일일이 집어서 냉각조에 투입하고 이를 다시 꺼내서 다음 단계의 가공을 거쳐야 하므로 제품의 생산성이 저하되는 문제점이 있었다. 또한, 열처리된 피가공물을 지그로 체결하여 냉각조로 이동시켜 냉각하는 방법은 납작한 판상의 피가공물을 일일이 지그로 체결하거나 꺼내는 과정이 매우 번거로워서 생산성이 매우 낮아지며, 지그에 의해 제품의 변형이 일어나는 문제점이 있었다.By the way, the free fall cooling method is to drop the heat-treated high-temperature product to the cooling water of the cooling tank rapidly, so that the deformation of the product occurs by the impact or rapid cooling, such as not only deteriorate the quality, but also heat-treated product There was a problem in that the productivity of the product is reduced because it is to be picked up and put into the cooling tank and take it out again to go through the next step of processing. In addition, the method of fastening the heat-processed workpiece with a jig and moving it to a cooling tank is a very cumbersome process of fastening or removing a flat plate-like workpiece with a jig one by one, and the productivity is very low. there was.
본 고안은 전술한 바와 같은 문제점을 해결하기 위한 것으로서, 본 고안의 목적은 열처리된 피가공물의 변형을 효율적으로 방지하여 품질을 향상시키고, 연속적으로 피가공물을 냉각시킴으로써 생산성을 증진시킬 수 있도록 된 열처리용 냉각장치를 제공하는 것이다.The present invention is to solve the problems as described above, the object of the present invention is to improve the quality by effectively preventing the deformation of the heat-treated workpiece, and to continuously improve the productivity by cooling the workpiece It is to provide a cooling device for.

이하, 본 고안의 바람직한 실시예를 첨부한 도면에 의거하여 설명하면 다음과 같다.Hereinafter, described with reference to the accompanying drawings, preferred embodiments of the present invention is as follows.
도 1은 본 고안에 따른 열처리용 냉각장치의 실시예를 도시한 것이다. 본 고안에 의한 열처리용 냉각장치는 상하 한 쌍의 메쉬벨트(41)가 상하로 밀착된 상태에서 냉각조(20) 내부에 하향 경사지도록 설치된 콘베이어기구(40)와, 이 콘베이어기구(40)의 타단에 설치된 반출수단(50)으로 구성된다.1 illustrates an embodiment of a cooling apparatus for heat treatment according to the present invention. The cooling apparatus for heat treatment according to the present invention includes a conveyor mechanism 40 installed to be inclined downward in the cooling tank 20 in a state where the pair of upper and lower mesh belts 41 are in close contact with each other up and down, and the conveyor mechanism 40 It is comprised of the carrying-out means 50 installed in the other end.
상기 냉각조(20)는 상부가 개방된 저수조로서, 제품을 고온으로 가열하는 가열로(10)와 연결되며 그 내부에는 냉각수가 채워져 있다. 또한, 이 냉각조(20)는 소정 위치에 교반모터(32)와 이 교반모터(32)의 축에 연결되어 회전하는 교반프로펠러(34)가 구비되어, 이 교반프로펠러(34)가 회전하면서 냉각조(20)의 냉각수를 교반하여 가열된 피가공물(12)이 신속하고 균일하게 냉각되도록 한다.The cooling tank 20 is a water tank having an open top, and is connected to a heating furnace 10 for heating a product at a high temperature, and a cooling water is filled therein. In addition, the cooling tank 20 is provided with a stirring motor 32 and a stirring propeller 34 which is connected to the shaft of the stirring motor 32 and rotates at a predetermined position, and the stirring propeller 34 is cooled while rotating. The cooling water in the bath 20 is stirred to allow the heated workpiece 12 to be cooled quickly and uniformly.
상기 콘베이어기구(40)는 상하로 밀착배치된 한 쌍의 메쉬벨트(41)와, 이 각 메쉬벨트(41)의 양측에 구비된 구동로울러(42)와, 이 각 메쉬벨트(41)의 밀착면에 상하 대칭적으로 구비된 다수개의 가이드로울러(44)로 구성된다. 여기서, 상기 콘베이어기구(40)에 의해 이송되는 피가공물(12)의 이송경로에 근접된 위치에 분사노즐(46)이 설치되는데, 이는 냉각수를 교란시켜 저온의 냉각수가 균일하게 제품에 분사되도록 한다.The conveyor mechanism 40 has a pair of mesh belts 41 closely arranged up and down, drive rollers 42 provided on both sides of each of the mesh belts 41, and the mesh belts 41 are in close contact with each other. It is composed of a plurality of guide rollers 44 provided symmetrically on the surface. Here, the injection nozzle 46 is installed at a position close to the conveying path of the workpiece 12 conveyed by the conveyor mechanism 40, which disturbs the cooling water so that the low temperature cooling water is uniformly sprayed on the product. .
상기 반출수단(50)은 그 일단이 상기 콘베이어기구(40)의 타단에 상향으로 경사지도록 설치되는 것으로서, 그 일단은 냉각조(20)의 냉각수에 잠기고 타단은 냉각조(20)의 밖으로 연장되어 있으며, 그 상면에는 소정 간격으로 다수개의 걸림돌기(52)가 형성되어 피가공물(12)을 걸어서 올릴 수 있다.The discharging means 50 is installed so that one end is inclined upward to the other end of the conveyor mechanism 40, one end is immersed in the cooling water of the cooling tank 20 and the other end is extended out of the cooling tank 20 In addition, a plurality of engaging projections 52 are formed on the upper surface at predetermined intervals so that the workpiece 12 can be raised by walking.
이와 같이 구성된 열처리용 냉각장치는, 열처리로(10)에서 고온으로 가열된 원형톱 등의 납작한 피가공물(12)을 밀착배치된 한 쌍의 메쉬벨트(41) 사이에 견고하게 지지한 상태에서 냉각조(20) 내부로 연속적으로 이송하면서 냉각시키며, 이렇게 냉각된 피가공물(12)을 상기 반출수단(50)의 걸림돌기(52)에 걸리도록 하여 냉각조(20) 밖으로 연속적으로 반출시킨다.The heat treatment cooling device configured as described above is cooled in a state in which the flat workpiece 12 such as a circular saw heated at a high temperature in the heat treatment furnace 10 is firmly supported between a pair of mesh belts 41 closely arranged. Cooling while continuously transported to the inside of the tank 20, the workpiece 12 thus cooled is caught by the locking projection 52 of the carrying out means 50 is continuously carried out of the cooling tank 20.
따라서, 상기 열처리용 냉각장치는 고온으로 열처리된 원형톱 등의 납작한 피가공물(12)을 상하 대칭으로 구비된 한 쌍의 메쉬벨트(41) 사이에서 견고하게 지지된 상태에서 연속적으로 이송시켜 냉각시킴으로써 변형이 발생되지 않도록 하며, 냉각된 피가공물(12)을 냉각조(20) 밖으로 연속적으로 반출시키므로 제품의 품질과 생산성을 증진시킬 수 있다.Therefore, the heat treatment cooling apparatus continuously cools the workpiece 12, such as a circular saw heat-treated at high temperature, by continuously transporting it in a firmly supported state between a pair of mesh belts 41 provided vertically and symmetrically. Deformation does not occur, and because the cooled workpiece 12 is continuously taken out of the cooling tank 20, it is possible to improve the quality and productivity of the product.
이상에서와 같이 본 고안에 따른 열처리용 냉각장치는 상대적으로 취급이 곤란한 원형톱과 같은 납짝한 열처리제품을 상하 대칭으로 구비된 한 쌍의 메쉬벨트 사이에서 견고하게 지지된 상태에서 연속적으로 냉각조에 투입하여 냉각함으로써 변형을 방지하므로 제품의 품질을 향상시키며, 냉각조 밖으로 제품을 연속적으로 반출시킴으로써 생산성을 증진시킬 수 있는 장점이 있다.As described above, the cooling device for heat treatment according to the present invention continuously inputs a heat treatment product such as a circular saw, which is relatively difficult to handle, to a cooling tank continuously while being firmly supported between a pair of mesh belts provided with symmetrical top and bottom symmetry. This prevents deformation by cooling, thereby improving the quality of the product, and has the advantage of increasing productivity by continuously taking the product out of the cooling tank.
