이로써, 이송롤러를 따라 이동되는 슬래브가 절단 위치에 도달되면 상부날 또는 하부날이 수직 방향으로 이동되면서 슬래브를 절단하게 된다.Thus, when the slab moved along the feed roller reaches the cutting position, the slab is cut while the upper blade or the lower blade is moved in the vertical direction.

종래 기술에 따른 연주설비용 슬래브 절단기는 고온의 슬래브를 장시간 동안 절단하게 되면 상부날 또는 하부날이 변형되거나 파손되는 문제점이 있다.The slab cutter for a performance facility according to the prior art has a problem that the upper blade or the lower blade is deformed or broken when cutting the hot slab for a long time.

이러한 과정에서 도면에 도시된 선들의 두께나 구성요소의 크기 등은 설명의 명료성과 편의상 과장되게 도시되어 있을 수 있다.In this process, the thickness of the lines or the size of the components shown in the drawings may be exaggerated for clarity and convenience of description.

또한, 후술되는 용어들은 본 발명에서의 기능을 고려하여 정의된 용어들로써, 이는 사용자, 운용자의 의도 또는 관례에 따라 달라질 수 있다.In addition, terms to be described later are terms defined in consideration of functions in the present invention, which may vary according to a user's or operator's intention or custom.

그러므로 이러한 용어들에 대한 정의는 본 명세서 전반에 걸친 내용을 토대 로 내려져야 할 것이다.Therefore, the definitions of these terms should be based on the contents throughout the specification.

도 1은 본 발명의 일 실시예에 따른 연주설비용 슬래브 절단기가 도시된 구성도이고, 도 2는 본 발명의 일 실시예에 따른 연주설비용 슬래브 절단기의 냉각부가 도시된 확대도이다.1 is a block diagram showing a slab cutter for a performance equipment according to an embodiment of the present invention, Figure 2 is an enlarged view showing a cooling unit of the slab cutter for a performance equipment according to an embodiment of the present invention.

도 1 및 도 2를 참조하면, 본 발명의 일 실시예에 따른 연주설비용 슬래브 절단기는 연주공정에 의해 제작되는 슬래브(10)의 이동 경로에 구비되는 하부날(54)과, 슬래브(10) 이동 경로에 유동 가능하게 구비되어 슬래브(10)를 절단하는 상부날(52)과, 하부날(54) 및 상부날(52)에 구비되어 냉각수를 공급하는 냉각부(70)를 포함한다.1 and 2, the slab cutter for a performance equipment according to an embodiment of the present invention is the lower blade 54 and the slab 10 provided in the movement path of the slab 10 produced by the playing process It is provided in the movement path and the upper blade 52 for cutting the slab 10, and the lower blade 54 and the cooling unit 70 is provided on the upper blade 52 to supply the cooling water.

이로써, 연주설비에 의해 제작된 슬래브(10)는 이송롤러(30)를 따라 이동하게 되는데, 구매자의 취향에 맞는 길이로 제작하기 위해 하부날(54) 및 상부날(52)로 이루어지는 절단기(50)가 구동되고, 장시간 동안 절단작동이 진행된 후에는 냉각부(70)로부터 공급되는 냉각수에 의해 하부날(54) 및 상부날(52)을 냉각시키게 된다.Thus, the slab 10 produced by the playing equipment is moved along the feed roller 30, the cutter 50 consisting of the lower blade 54 and the upper blade 52 to produce a length that suits the taste of the buyer. ) Is driven and the lower blade 54 and the upper blade 52 are cooled by the coolant supplied from the cooling unit 70 after the cutting operation is performed for a long time.

이러한 냉각작동에 의해 하부날(54) 및 상부날(52)이 과열에 의해 변형되거나 파손되는 것을 억제할 수 있게 된다.By this cooling operation, the lower blade 54 and the upper blade 52 can be suppressed from being deformed or damaged by overheating.

냉각부(70)는 하부날(54) 및 상부날(52)에 구비되는 노즐(72)과, 노즐(72)에 연결되어 냉각수를 공급하는 급수관(74)을 포함한다.The cooling unit 70 includes a nozzle 72 provided on the lower blade 54 and the upper blade 52, and a water supply pipe 74 connected to the nozzle 72 to supply cooling water.

펌프의 구동에 의해 냉각수가 공급되면 급수관(74)을 따라 유동되는 냉각수가 절단기(50)에 설치된 노즐(72)까지 공급되고, 노즐(72)을 따라 절단기(50) 측으 로 분사되므로 하부날(54) 및 상부날(52)에 냉각수가 접촉되면서 슬래브(10)로부터 전달된 열이 냉각수로 전달된다.When the coolant is supplied by the driving of the pump, the coolant flowing along the water supply pipe 74 is supplied to the nozzle 72 installed in the cutter 50, and sprayed toward the cutter 50 along the nozzle 72 so that the lower blade ( 54 and the upper blade 52 is in contact with the coolant is transferred heat from the slab 10 to the coolant.

하부날(54)에 분사된 냉각수는 슬래브(10)로부터 전달된 열을 흡수하여 하측으로 흐르기 때문에 냉각수와 슬래브(10)가 접촉되는 것을 억제할 수 있게 되므로 냉각수에 의해 슬래브(10)가 필요 이상으로 냉각되는 것이 방지되어 슬래브(10) 조직의 상태가 변화되는 것을 방지할 수 있게 된다.Since the coolant sprayed on the lower blade 54 absorbs the heat transferred from the slab 10 and flows downward, the coolant and the slab 10 can be prevented from contacting the coolant so that the slab 10 is more than necessary by the coolant. Cooling can be prevented so that the state of the slab 10 tissue can be prevented from changing.

또한, 상부날(52)에 구비되는 급수관(74)에는 공기를 공급하는 분기관(76)이 구비되므로 상부날(52)에 분사되는 냉각수 중에는 공기가 포함된다.In addition, since the water supply pipe 74 provided on the upper blade 52 is provided with a branch pipe 76 for supplying air, air is included in the cooling water sprayed on the upper blade 52.

이로써, 상부날(52)에 냉각수가 분사됨과 동시에 공기가 분사되므로 분사되는 냉각수가 비산(飛散)되는 효과가 나타나게 된다.As a result, the cooling water is injected to the upper blade 52 and at the same time, the air is injected, so that the sprayed cooling water is scattered.

이렇게 냉각수가 비산되면 작은 입자로 분산된 물입자가 상부날(52) 표면에 흡착되므로 하측 방향으로 떨어지는 냉각수가 없어지게 되며, 상부날(52)에 흡착된 미세한 물입자는 큰 물입자로 뭉쳐져 하측 방향으로 흐르기 전에 고온의 상부날(52)에 의해 증발되므로 냉각수가 상부날(52)을 따라 하측 방향으로 흐르는 것을 방지할 수 있게 된다.When the coolant is scattered, water particles dispersed in small particles are adsorbed on the upper blade 52, so that the coolant falling in the lower direction disappears, and the fine water particles adsorbed on the upper blade 52 are aggregated into larger water particles and lowered. Since it is evaporated by the high temperature upper blade 52 before flowing in the direction, it is possible to prevent the coolant flowing in the lower direction along the upper blade 52.

물론, 냉각수를 비산시키기 위해서는 고압의 공기를 공급하는 것이 바람직하며, 분기관(76)을 따라 고압의 공기를 공급하기 위한 기술구성, 즉 압력용기나 송풍팬, 펌프 등의 장치는 본 발명의 기술구성을 인지한 당업자가 쉽게 실시할 수 있는 것이므로 구체적인 도면이나 설명은 생략하기로 한다.Of course, it is preferable to supply high pressure air in order to scatter the cooling water, and a technical configuration for supplying high pressure air along the branch pipe 76, that is, a device such as a pressure vessel, a blowing fan, a pump, and the like is a technique of the present invention. Since a person skilled in the art having the configuration can be easily implemented, specific drawings or descriptions will be omitted.

또한, 급수관(74)을 따라 냉각수를 공급하기 위한 장치 역시 본 발명의 기술 구성을 인지한 당업자가 용이하게 실시할 수 있으므로 구체적인 도면이나 설명은 생략하기로 한다.In addition, the apparatus for supplying the cooling water along the water supply pipe 74 can also be easily implemented by those skilled in the art who recognizes the technical configuration of the present invention will not be described in detail or description.

상기와 같이 구성된 본 발명의 일 실시예에 따른 연주설비용 슬래브 절단기의 동작을 살펴보면 다음과 같다.Looking at the operation of the slab cutter for playing equipment according to an embodiment of the present invention configured as described above are as follows.

먼저, 연주공정에 의해 슬래브(10)가 제작되면 이송롤러(30)를 따라 이동하게 되는데, 이때 구매자가 원하는 길이의 제품을 제작하기 위해 절단기(50)가 구동된다.First, when the slab 10 is produced by the playing process is moved along the feed roller 30, the cutter 50 is driven to produce a product of the desired length buyer.

절단기(50)가 구동되면, 상부날(52)이 하측 방향으로 유동되어 하부날(54)과 맞닿게 되므로 상부날(52)과 하부날(54) 사이를 통과하는 슬래브(10)의 절단이 이루어지게 된다.When the cutter 50 is driven, the cutting edge of the slab 10 passing between the upper blade 52 and the lower blade 54 because the upper blade 52 flows downward to contact the lower blade 54. Will be done.

이러한 절단공정이 장시간 이루어지게 되면 하부날(54)과 상부날(52)이 고온의 슬래브(10)와 반복적으로 접촉되므로 필요 이상으로 과열되는데, 이때, 급수관(74)을 따라 공급되는 냉각수가 하부날(54)과 상부날(52)에 분사되어 절단기(50)가 필요 이상으로 과열되는 것을 방지할 수 있게 된다.When such a cutting process is performed for a long time, the lower blade 54 and the upper blade 52 repeatedly overheat with the high-temperature slab 10, and thus are overheated more than necessary. In this case, the cooling water supplied along the water supply pipe 74 is lowered. It is sprayed on the blade 54 and the upper blade 52 to prevent the cutter 50 from overheating more than necessary.

여기서, 절단작동은 상부날(52)의 하강에 의해 이루어지거나, 상부날(52)의 하강과 동시에 구동되는 하부날(54)의 상승에 의해 이루어지게 된다.Here, the cutting operation is made by the lowering of the upper blade 52, or by the rising of the lower blade 54 which is driven simultaneously with the lowering of the upper blade 52.

물론, 상부날(52) 및 하부날(54)의 구동 외에 다양한 절단작동이 적용될 수 있으며, 본 발명의 기술구성을 인지한 당업자가 용이하게 변경하여 실시할 수 있는 것이므로 구체적인 도면이나 설명은 생략하기로 한다.Of course, in addition to the operation of the upper blade 52 and the lower blade 54, various cutting operations may be applied, and those skilled in the art who have recognized the technical configuration of the present invention can be easily changed and carried out specific drawings or descriptions will be omitted. Shall be.

또한, 상부날(52)에 분사되는 냉각수는 분기관(76)을 따라 공급되는 고압의 공기가 노즐(72)을 따라 동시에 분사되므로 상부날(52) 측으로 분사되는 공기는 고압의 공기가 분사됨과 동시에 냉각수가 비산되어 상부날(52) 외벽에 흡착된다.In addition, the coolant injected to the upper blade 52 is a high-pressure air supplied along the branch pipe 76 at the same time is injected along the nozzle 72, the air injected to the upper blade 52 side is the high-pressure air is injected and At the same time, the coolant is scattered and adsorbed to the outer wall of the upper blade 52.

이렇게 상부날(52)의 표면에 흡착된 냉각수 입자는 고온의 상부날(10)에 의해 증발되므로 냉각수가 상부날(52)을 따라 하측 방향으로 흐르는 것이 억제되어 냉각수와 슬래브(10)가 접촉되는 것을 방지할 수 있게 된다.Since the coolant particles adsorbed on the surface of the upper blade 52 is evaporated by the high temperature upper blade 10, the cooling water is suppressed from flowing downward along the upper blade 52 so that the cooling water and the slab 10 come into contact with each other. Can be prevented.

이로써, 고온의 슬래브(10)를 장시간 동안 절단하여 발생되는 변형 및 파손을 억제하는 연주설비용 슬래브 절단기를 제공할 수 있게 된다.As a result, it is possible to provide a slab cutter for a performance facility that suppresses deformation and breakage caused by cutting the hot slab 10 for a long time.

Will understand.

또한, 상부날 및 하부날이 구비되는 연주설비용 절단기를 예로 들어 설명하였으나, 이는 예시적인 것에 불과하며, 상부날 및 하부날이 구비되는 연주설비용 절단기가 아닌 다른 제품에도 본 발명의 절단기가 사용될 수 있다.In addition, the cutting equipment for the performance equipment provided with the upper blade and the lower blade has been described as an example, but this is merely illustrative, the cutter of the present invention may be used in other products other than the cutting equipment for the performance equipment provided with the upper blade and the lower blade.
