본 고안은 선재공장에 갖춰진 절단장치(shear)에 관한 것으로, 특히 선재의 선단부를 절단하여 발생된 크롭의 길이를 최소화함으로서 선재 제품이 실수율을 향상시키고, 설비고장을 방지하며, 안전사고를 예방하도록 개선된 선재절단기의 크롭유도 낙하장치에 관한 것이다.The present invention relates to a cutting device (shear) equipped in the wire rod factory, in particular to minimize the length of the crop generated by cutting the end of the wire rod to improve the wire rod product error rate, prevent equipment failure, and prevent safety accidents A crop induction dropping device for an improved wire cutting machine.

일반적으로 선재공장에 갖춰진 절단장치(Shear)(100)는 제4도에 도시된 바와 같이 선재(C)를 절단하는 쵸핑전단장치(chopping shear)(110)와, 선재(C)를 후속 압연라인(120)으로 이송하거나 코볼 전단장치(130)로 이송하는 플랩(Flap)방향전환장치(140)가 갖춰지며, 상기 플랜 방향 전환장치(140)는 선재(C)를 절단하여 발생되 크롭(k)을 하부로 유도시켜 스크랩 박스(160)에서 수거하도록 방향전환 시키는 기능도 갖고 있다. 상기와 같은 절단장치(100)는 선재공장에서 선재(C)의 압연중에 선재(C)의 선단부를 제3도에 도시된 바와 같은 쵸핑 절단장치(110)의 상, 하 전단날(112a)(112b)에서 전단하여야만 하는바, 이는 선재(C)의 선단부가 다른부분보다 과냉된 상태이기때문에 이러한 과냉된 부분은 다음의 압연 스탠드롤에 진입이 잘 이루어지지 않음으로서 절단하여 제거하며, 이때 전단된 선재의(C)의 선단부를 크롭(K)(Crop)이라고 부른다. 한편, 상기와 같은 종래의 크롭길이는 과냉부분이 30㎜로서 대략 50㎜정도만 절단하면 되지만, 실제로는 1000㎜가 절단되어야 만하며 따라서 불필요하게 긴 길이을 절단하는 것이었다. 이는 선재의 이동속도가 75m/sec로서 매우 고속이고, 쵸핑 절단장치(110)후방의 플랩방향전환장치(140)의 1싸이클이 대략 0.05초이며, 쵸핑 절단장치(110)와 플랩방향 전환장치(140)사이의 거리가 1000㎜정도이다.In general, the cutting device 100 equipped with the wire rod factory has a chopping shear 110 for cutting the wire rod C, as shown in FIG. A flap redirection device 140 for transferring to the 120 or the coball shearing device 130 is provided, and the plan redirection device 140 is generated by cutting the wire rod C. It also has a function to change the direction to be guided to the bottom to collect from the scrap box 160. The cutting device 100 as described above is the upper and lower shear blades 112a of the chopping cutting device 110 as shown in FIG. 3 during the rolling of the wire rod C in the wire rod factory. It should be sheared at 112b), since the tip of the wire rod (C) is supercooled than other parts, and this supercooled portion is cut off and removed due to poor entry into the next rolling stand roll. The tip of the wire rod C is referred to as crop K. On the other hand, in the conventional crop length as described above, the subcooled portion only needs to cut about 50 mm as 30 mm, but in reality, 1000 mm must be cut and thus unnecessarily long length is cut. The movement speed of the wire rod is 75m / sec, very high speed, one cycle of the flap turning device 140 behind the chopping cutting device 110 is approximately 0.05 seconds, and the chopping cutting device 110 and the flap direction switching device ( 140) is about 1000 mm.

따라서 쵸핑 절단장치(110)에서 선재를 절단한 순간 플랩방향전환장치(140)는 제4도의 a도에서 실선으로부터 점선으로 회동되어 코블(k)이 선단부를 하부로 타격함으로서 절단된 1,000㎜길이의 코블(K)은 스크랩 수거박스(160)로 낙하되어 폐기처리되는 것이다. 만일 1,000㎜길이로서 코블(k)을 절단하지 않고, 제4도의 b)도에 도시된 바와 같이 대략 코블(k)의 길이를 50㎜로 절단하는 경우는 쵸핑 절단장치(110)가 50㎜길이의 코블(k)을 절단하는 순간, 플랩 방향전환 장치(140)는 제4도의 b)도에서와 같이 하부로 스윙(swing)동작을 하지만 절단된 50㎜길이의 코블(k)과는 접촉되지 못하며 따라서 50㎜길이의 코블(k)은 방향전환되지 않은 상태에서 진행하는 탄성력에 의해서 전진하며 플랩 방향장치(140)가 하향 회동한 순간이를 통과하여 후속 압연라인 속으로 진입하는 것이다. 따라서 이러한 코블(140)부재가 후속단면 라인에 존재하면 후행(後行)하는 선재(C)가 후속단면 라인으로 진입하는 경우 압연이 불가능하여 설비 고장의 주요원인으로 하는 것이었다. 따라서 선재(C)의 선단부에서 절단되는 코블(k)의 길이는 반드시 1,000㎜로 절단되어야 하며 이러한 크롭 발생량은 1,5ton/日에 해당하는 다량이기 때문에 불필요한 완제품의 실수율저하가 초래되는 것이고, 설비 고장 및 파손은 물론, 작업자가 설비를 보수유지함에 따른 안전사고등이 발생하는 것이었다. 본 고안은 상기와 같은 종래의 문제점을 해소하기 위한 것으로, 크롭의 길이를 최소화하여 압연 실수율을 크게 향상시키고, 설비 사고를 예방함은 물론, 설비 가동율향상에 따른 정비 작업자의 안전사고도 예방할 수 있는 선재 절단기의 크롭 유도 낙하장치를 제공함에 그 목적이 있다. 상기 목적을 달성하기 위하여 본 고안은, 선재 압연설비의 선재절단 장치에 있어서, 쵸핑 절단장치의 상부 절단날, 후면에는 절단날의 후방측으로 돌출된 크롭을 하부로 눌러주는 크롭누름판이 장착되고, 하부 절단날의 전면에는 크롭이 제거된 압연선재의 전단부를 상승시키기 위한 선재상승유를 일체로 장착하며, 쵸핑 절단장치와 플랜 방향 전환장치사이에는 크롭가이드가 장착됨을 특징으로 하는 선재절단기의 크롭 유도낙하장치를 마련함에 의한다.Accordingly, the flap redirection device 140 is rotated from the solid line to the dotted line in the a diagram of FIG. 4 at the moment when the chopping cutting device 110 cuts the wire rod. Cobble K is dropped into the scrap collection box 160 is disposed of. If the length of the cobbles k is cut to 50 mm as shown in b) of FIG. 4 without cutting the cobbles k as 1,000 mm in length, the chopping cutting device 110 is 50 mm long. At the moment of cutting the cobble k of the flap, the flap redirection device 140 swings downward as shown in b) of FIG. 4 but is not in contact with the cut 50 mm length of the cobble k. Therefore, the 50 mm length coble k is advanced by the elastic force that proceeds in the unturned state and passes through the moment when the flap direction device 140 rotates downward to enter the subsequent rolling line. Therefore, when such a cobble 140 member is present in the subsequent cross-section line, when the trailing wire (C) enters the subsequent cross-section line, rolling is impossible, which is the main cause of equipment failure. Therefore, the length of the cobbles (k) cut at the end of the wire rod (C) must be cut to 1,000 mm and this crop generation amount is 1,5 tons / day is a large amount that will result in unnecessary decrease in the error rate of the finished product, equipment In addition to breakdowns and damages, safety accidents occurred as workers maintained the equipment. The present invention is to solve the conventional problems as described above, by minimizing the length of the crop to greatly improve the rolling error rate, and prevent the equipment accidents, as well as to prevent the safety accidents of maintenance workers according to the improvement of the equipment operation rate It is an object of the present invention to provide a crop induction dropping device of a wire cutting machine. In order to achieve the above object, the present invention, in the wire cutting device of the wire rod rolling equipment, the top cutting blade of the chopping cutting device, the rear side is equipped with a crop pressing plate for pressing the crop projected to the rear side of the cutting blade to the bottom, The front of the cutting blade is equipped with a wire rod rising oil to raise the front end of the rolled wire without the crop, and the crop guide is installed between the chopping cutting device and the planar direction changing device. By providing a device.

이하, 본 고안을 도면에 따라서 보다 상세히 설명한다.Hereinafter, the present invention will be described in more detail with reference to the drawings.

제1도에는 본 고안에 따른 크롭 유도낙하장치(1)가 도시되어 있다. 상기 크롭 유도낙하 장치(1)는 쵸핑 절단장치(110)의 상부 절단날(120)의 후면측에 크롭 누름판(10a)이 다수개의 보울트 부재(12)로서 장착되는바, 상기 크롭 누름판(10a)이 상부전단날(112a)에 고정되면, 크롭누름판(10a)의 하단부(14)가 상부 절단날(112a)의 하단부(113a)보다 길게 하향 연장 되어있다. 또한, 상기 쵸핑 절단장치(110)의 하부 절단날(112b)전면측에는 선재 상승슈(10b)가 다수개의 보울트 부재(16)를 통하여 일체로 장착되는바, 상기 선재 상승슈(10b)는 상단부(17)가 둥근 머리부를 형성하면서 하부 절단날(112b)의 상단부(17)보다 다소 높게; 대략 5㎜정도 상승된 상태로 장착되는 것이다. 또한, 상기와 같은 쵸핑 절단장치(110)의 후방에는 플랩 방향전환 장치(140)의 전방측으로 크롭 가이드(30)가 다수개의 보울트 부재(31)에 의해서 일체로 고정장착되며 상기 크롭 가이드(30)는 전방 측으로 경사를 형성하여 뾰족한 전방 모서리(32)를 형성하는 것이다. 상기와 같이 구성된 본 고안은, 선재의(c)의 과냉된 선단부를 절단하고자 하는 경우, 크롭(K)의 길이가 100㎜로 유지되도록 쵸핑절단장치(110)를 동작시키게 된다. 이러한 경우 쵸핑 절단장치(110)는 제1도에 도시된 바와 같이 상, 하부 절단날(112a)(112b)이 서로 반대 방향으로 회동하면서 선재(c)를 절단하는 경우 상부 절단날(112a)에 부착된 크롭 누름판(10a)이 선재(c)의 100㎜크롭(K)부위를 하부로 눌러주게 되며, 하부절단날(112b)에 부착된 선재 상승류(10b)는 상, 하부 절단날(112a)(112b)전방의 압연 선재(C)를 상승시켜 주게 된다. 따라서, 상, 하부 절단날(112a)(112b)이 100㎜의 크롭을 절단하는 순간, 상기 크롭 누름판(10a)에 의해서 100㎜의 크롭(k)은 하부측으로 압압되어 후방측의 크롭 가이드(30) 하부측으로 낙하되고, 100㎜의 크롭(k)이 절단된 압연선재(C)는 선재 상승슈(10b)에 의해서 대략 5㎜상승된 상태이기 때문에 상부측으로 향하면서 크롭가이드(30)의 상부측을 지나, 후방측의 압연 스탠드로 향하게 된다. (제2도 참조) 이러한 과정에서 상부 절단날(112a)에 부착된 크롭 누름판(10a)과, 하부 절단날(112b)에 부착된 선재 상승슈(10b)는 상기 상, 하부 절단날(112a)(112b)의 회동작동에 아무런 장해도 주지 않게 되며, 이는 하부 절단날(112b)이 선재를 절단하는 장점에 도달하기 전에 크롭 누름판(10a)이 먼저 상기 상, 하부 절단날(112a)(112b)의 절단지점을 통과하고, 상기 크롭 누름판(10a)이 지나간 다음에 상, 하부 절단날(112a)(112b)이 선재(c)를 절단하여 100㎜의 크롭(k)을 형성하기 때문이다. 상기에서와 같이 본 고안에 의하면, 크롭의 길이를 종래의 1,000㎜에서 100㎜로 크게 감소시킬 수 있기 때문에 압연 선재의 실수율이 크게 향상된다. 뿐만아니라, 적은 크기로 절단된 크롭은 안전하게 하부로 낙하 유도되어 스크랩 박스에서 수거되기 때문에 설비 고장등을 발생시키지 않으며, 설비 가동율의 향상에 따른 정비작업자의 안전사고가 예방되는 등 실용상의 효과를 얻는 것이다.1 shows a crop induction dropping apparatus 1 according to the present invention. The crop induction dropping device 1 has a cropping plate 10a mounted on the rear side of the upper cutting blade 120 of the chopping cutting device 110 as a plurality of bolt members 12, the cropping plate 10a. When the upper shear blade 112a is fixed, the lower end portion 14 of the crop pressing plate 10a extends downward longer than the lower end portion 113a of the upper cutting edge 112a. Further, the wire rod rising shoe 10b is integrally mounted on the front side of the lower cutting blade 112b of the chopping cutting device 110 through the plurality of bolt members 16, and the wire rod rising shoe 10b has an upper end portion ( 17) is somewhat higher than the upper end 17 of the lower cutting blade 112b while forming a round head; It is mounted in a raised state of about 5 mm. In addition, the cropping guide 30 is fixedly mounted to the front side of the flap redirection device 140 by the plurality of bolt members 31 at the rear of the chopping cutting device 110 as described above, and the crop guide 30 Is to form a slanted front edge 32 by forming an inclination toward the front side. According to the present invention configured as described above, when the supercooled tip of the wire rod (c) is to be cut, the chopping cutting device 110 is operated so that the length of the crop K is maintained at 100 mm. In this case, as shown in FIG. 1, the chopping cutting device 110 is connected to the upper cutting blade 112a when the upper and lower cutting blades 112a and 112b rotate in the opposite directions to cut the wire rod c. The attached crop pressing plate 10a presses the 100 mm crop K portion of the wire rod c downwardly, and the wire rod upward flow 10b attached to the lower cutting edge 112b is upper and lower cutting edges 112a. The rolled wire C in front of the 112b is raised. Therefore, at the moment when the upper and lower cutting edges 112a and 112b cut the crop of 100 mm, the crop k of 100 mm is pressed to the lower side by the crop pressing plate 10a, and the crop guide 30 on the rear side is pressed. ) The rolled wire C, which is dropped to the lower side and cuts the crop k of 100 mm, is in a state of approximately 5 mm ascended by the wire rod rising shoe 10b, so that the upper side of the crop guide 30 is directed toward the upper side. Passing through, it is directed to the rolling stand on the rear side. (See FIG. 2) In this process, the crop pressing plate 10a attached to the upper cutting blade 112a and the wire rising shoe 10b attached to the lower cutting blade 112b are the upper and lower cutting blades 112a. There is no obstacle to the rotational operation of the 112b, which means that the crop pressing plate 10a first starts the upper and lower cutting edges 112a and 112b before the lower cutting edge 112b reaches the advantage of cutting the wire rod. This is because the upper and lower cutting edges 112a and 112b cut the wire c to form a crop k of 100 mm after passing through the cutting point of and passing the crop pressing plate 10a. According to the present invention as described above, since the length of the crop can be greatly reduced from the conventional 1,000 mm to 100 mm, the error rate of the rolled wire rod is greatly improved. In addition, crops cut to a small size are safely dropped to the lower part and collected from the scrap box, thus eliminating equipment breakdowns and preventing practical accidents caused by the improvement of facility utilization rate. will be.
