이하, 첨부된 도면을 참조하여 본 발명의 바람직한 실시예를 상세하게 설명한다. 도면들 중 동일한 구성요소들은 가능한 어느 곳에서든지 동일한 부호로 표시한다. 또한 본 발명의 요지를 불필요하게 흐릴 수 있는 공지 기능 및 구성에 대한 상세한 설명은 생략한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Like elements in the figures are denoted by the same reference numerals wherever possible. In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail.

압연롤의 한 종류인 슬리브롤은 서로 다른 특성을 지닌 이종 재질인 축과 슬리브를 결합시켜 제조할 수 있는데, 이 때 슬리브의 중공부에 축을 결합시키기 위하여 열박음 방법이 주로 사용되고 있다.Sleeve roll, which is a kind of rolling roll, can be manufactured by combining a shaft and a sleeve, which are different materials having different characteristics, and a shrink fit method is mainly used to couple the shaft to a hollow portion of the sleeve.

열박음 방법은 슬리브를 가열하여 중공부를 팽창시킨 후, 축을 결합하고 냉각시킴으로써 수축된 중공부로 축을 강하게 조이면서 결합 고정하는 방법이다. 이와 같은 열박음 방법의 시행 시, 슬리브는 위치의 이동을 위한 수평이동 및 가열로에 장입과 반출을 위한 수직이동이 이루어지는데, 본 발명의 슬리브 이송장치(100)를 이용하여 슬리브의 이송 작업을 용이하고 안전하게 시행할 수 있다.The shrink fit method is a method in which the sleeve is heated to expand the hollow portion, and then the shaft is coupled and cooled to tighten and fix the shaft to the contracted hollow portion. When the shrink fit method is implemented, the sleeve is horizontally moved for movement of the position and vertical movement for loading and unloading into the heating furnace. The sleeve conveying operation is performed using the sleeve conveying apparatus 100 of the present invention. It can be done easily and safely.

도 1은 본 발명의 실시예에 의한 열박음시 슬리브 이송장치의 사시도이다.1 is a perspective view of a sleeve conveying device when shrinking according to an embodiment of the present invention.

본 도면을 참조하면, 이송장치(100)는 걸림다리(110), 고정홀(115), 고정바(116), 연결플레이트(120), 및 폭조절수단(130)을 포함한다.Referring to this figure, the transfer device 100 includes a locking leg 110, a fixing hole 115, a fixing bar 116, a connecting plate 120, and a width adjusting means 130.

걸림다리(110)는 슬리브(S)의 중앙의 중공부에 삽입되는 부분으로서, 하단부에 외측으로 절곡된 걸림부(111)가 구비된 것이 특징이다. 걸림다리(110)는 내측변(113)이 경사지게 형성되는데, 구체적으로는 상부로 갈수록 폭이 넓고 하부로 갈수록 폭이 좁게 테이퍼지게 형성된다. Hanging leg 110 is a portion inserted into the hollow portion of the center of the sleeve (S), characterized in that the lower end portion is provided with a locking portion bent outward 111. The engaging leg 110 is formed to be inclined to the inner side 113, specifically, the width is wider toward the top and the taper is narrower toward the bottom.

걸림부(111)는 걸림다리(110)의 하단부가 외측으로 돌출된 갈고리 형태로 형성되어, 도 2에서 처럼, 슬리브(S)의 중공부 내부로 끼워져 슬리브(S)의 밑단에 연접되도록 장착되는 부분이다. 즉, 슬리브(S)에 걸림부(111)를 장착시켜 수평수직 이송을 하게 되는 것이다.The catching part 111 is formed in the form of a hook in which the lower end of the catching leg 110 protrudes outward, and is inserted into the hollow part of the sleeve S to be connected to the bottom end of the sleeve S as shown in FIG. 2. Part. In other words, by mounting the engaging portion 111 to the sleeve (S) is to perform a horizontal vertical transfer.

또한, 걸림다리(110)에는 길이 방향으로 복수개의 관통홀이 이격된 슬리브 고정홀(115)이 형성된다. 슬리브 고정홀(115)은 슬리브를 고정시키기 위한 슬리브 고정바(116)가 삽입되는 구멍이다. 상기 걸림다리(110)는 복수개가 한 세트로 이루어져 있으며, 관통홀은 각각의 걸림다리(110)에서 동일한 높이에 동일한 개수로 형성되는 것이 특징이다. In addition, the locking leg 110 is formed with a sleeve fixing hole 115 spaced apart from the plurality of through holes in the longitudinal direction. The sleeve fixing hole 115 is a hole into which the sleeve fixing bar 116 is inserted to fix the sleeve. The hook leg 110 is composed of a plurality of sets, the through-hole is characterized in that formed in the same number at the same height in each hook leg (110).

슬리브 고정바(116)는 각각의 걸림다리(110)마다 한개씩 구비되며, 일정 높이의 슬리브 고정홀(115)에 끼워져 슬리브를 고정 지지한다. 구체적으로는 대기중에는 슬리브 고정바(116)가 걸림다리(110) 상단에 형성된 슬리브 고정홀(115)에 끼워져 있다가, 걸림다리(110)에 슬리브가 장착되면 슬리브 상단면 높이에 형성된 슬리브 고정홀(115)에 슬리브 고정바(116)를 끼워 슬리브가 이송 중 회전되거나 흔들리는 것을 방지하기 위하여 지지하는 것이다.One sleeve fixing bar 116 is provided for each engaging leg 110, and is fitted into the sleeve fixing hole 115 of a predetermined height to fix and support the sleeve. Specifically, in the air, the sleeve fixing bar 116 is inserted into the sleeve fixing hole 115 formed at the upper end of the locking leg 110, and when the sleeve is mounted on the locking leg 110, the sleeve fixing hole formed at the height of the sleeve upper surface. The sleeve fixing bar 116 is fitted to the 115 to support the sleeve in order to prevent it from rotating or shaking during transportation.

슬리브 고정바(116)의 단면 및 두께는 크게 제한되지 않으나, 슬리브 고정홀(115)에 장착 시 겉돌지 않도록 슬리브 고정홀(115)과 같은 단면형태 및 두께로 형성되어 세트를 이루는 것이 바람직하다. 또한 슬리브 고정바(116)의 길이도 크게 제한되지 않으나, 일반적으로 제조되는 슬리브에 연접되어 고정시킬 수 있도록 슬리브의 일측 평면두께(d)에 대응되는 길이로 형성되는 것이 좋다.The cross section and thickness of the sleeve fixing bar 116 are not particularly limited, but it is preferable that the sleeve fixing bar 116 is formed in the same cross-sectional shape and thickness as the sleeve fixing hole 115 so as not to turn over when the sleeve fixing bar 116 is mounted. In addition, the length of the sleeve fixing bar 116 is not particularly limited, but is generally formed to have a length corresponding to one side thickness (d) of the sleeve so as to be connected to and fixed to the sleeve being manufactured.

복수개의 걸림다리(110) 상부는 하나의 연결플레이트(120)의 둘레를 따라 방사상으로 이격되어 고정된다. 걸림다리(110)의 개수는 적어도 2개 이상 형성되어 슬리브 장착 후 이송 시에 좌우 균형을 맞추게 되는데, 바람직하게는 3개 내지 4개가 형성되는 것이 슬리브의 균형을 맞추는데 유리하며 설계 및 구현에 가능하다면 그 이상 개수의 걸림다리(110) 또한 가능하다. Upper portions of the plurality of hooking legs 110 are fixed radially spaced apart along the circumference of one connecting plate 120. At least two hook legs 110 are formed to balance left and right at the time of transfer after mounting of the sleeve. Preferably, three to four are formed to balance the sleeve and, if possible, for design and implementation. More than that number of legs 110 is also possible.

걸림다리(110)는 연결 각도의 변동이 가능하도록 회전축(119)에 의하여 연결플레이트(120)에 연결된다. 회전축(119)에 의하여 복수개의 걸림다리(110)들이 하나의 연결플레이트(120)에 연결된 채로 외부로 벌어져 걸림다리(110) 서로 간의 폭이 넓어지거나, 내부로 모아져 걸림다리(110) 서로 간의 폭이 좁아지는 것이 가능하게 된다.The locking leg 110 is connected to the connection plate 120 by the rotation shaft 119 so that the connection angle can be varied. The plurality of locking legs 110 are opened to the outside by being connected to one connection plate 120 by the rotating shaft 119 to widen the width of the locking legs 110 or to the inside of the locking legs 110. It becomes possible to narrow this.

걸림다리(110) 사이 폭의 변동은 폭조절수단(130)에 의하여 조절되는데, 폭조절수단(130)은 연결플레이트(120)의 중앙을 관통하는 축(131)으로서, 하단에 걸림다리(110)의 내측과 연접되는 원판(135)이 구비된다. 또한, 폭조절수단(130)의 상단에는 크레인(200)에 걸기 위한 이동고리(140)가 더 형성되며, 도 1의 A 부분에서 보듯이, 폭조절수단(130)에 구비된 원판(135)의 하단에는 걸림다리(110) 사이 폭을 좁히기 위하여 외부 고리에 고정시키기 위한 폭조절고리(136)가 더 형성된다.The fluctuation of the width between the engaging legs 110 is adjusted by the width adjusting means 130, the width adjusting means 130 is a shaft 131 penetrating through the center of the connecting plate 120, the locking leg 110 at the bottom There is provided a disc 135 in contact with the inner side. In addition, the upper end of the width adjusting means 130 is further formed with a moving ring 140 for hanging on the crane 200, as shown in part A of Figure 1, the disc 135 provided in the width adjusting means 130 The lower end of the width adjusting ring 136 for fixing to the outer ring in order to narrow the width between the hook 110 is further formed.

구체적으로는, 걸림다리(110) 사이 폭의 변동은 폭조절수단(130)의 원판(135)의 높이에 따라 달라진다. 원판(135)은 방사상으로 위치된 걸림다리(110)의 내측변(113)에 연접된 채로 상하로 이동하는데, 원판(135)이 상측으로 이동되면 걸림다리(110) 내측의 경사도에 따라 걸림다리(110) 사이 폭이 넓어지게 되고, 원판(135)이 하측으로 이동되면 걸림다리(110) 사이 폭이 좁아지게 되는 것이다.Specifically, the fluctuation of the width between the engaging legs 110 depends on the height of the disc 135 of the width adjusting means 130. The disc 135 moves up and down while being connected to the inner side 113 of the locking leg 110 positioned radially, and when the disc 135 is moved upward, the leg is caught according to the inclination of the inside of the locking leg 110. The width between the 110 is widened, and when the disc 135 is moved to the lower side is the width between the locking legs (110).

더욱 구체적으로는, 폭조절수단(130) 축(131)이 연결플레이트(120)를 상측방향으로 통과하면서 원판(135)이 상측으로 이동되면서 연접된 걸림다리(110) 내측변(113)을 바깥방향으로 밀어내어 걸림다리(110) 사이 폭을 넓히게 되고, 반대로 폭조절수단(130) 축(131)이 연결플레이트(120)를 하측방향으로 통과하면서 원판(135)이 하측으로 이동되면서 연접된 걸림다리(110)의 내측변(113)을 중심방향으로 모이도록 하여 걸림다리(110) 사이 폭을 좁히게 된다.More specifically, the width adjusting means 130, the shaft 131 passes through the connecting plate 120 in the upper direction, while the disc 135 is moved upward, the outer side 113 of the engaging leg 110 is joined. Direction to widen the width between the locking legs 110, on the contrary, while the width adjusting means 130, the shaft 131 passes through the connecting plate 120 in the downward direction, the hook 135 is moved downwards and connected By gathering the inner side 113 of the leg 110 in the center direction, the width between the engaging legs 110 is narrowed.

이를 위한 폭조절수단(130) 축(131)의 상하이동은 폭조절수단(130)의 최상측에 형성된 이동고리(140) 및 원판(135) 하단에 형성된 폭조절고리(136)에 고리 또는 크레인(200)을 걸어 외부에서 당겨줌으로써 시행시킬 수 있다. 구체적으로는 이동고리(140)에는 폭조절수단(130)을 상측으로 올리기 위하여 크레인(200)을 걸고, 폭조절고리(136)에는 바닥면에 고정되고 하측에서 당길 수 있도록 형성된 외부 고리를 걸어 주는 것이 좋다.For this purpose, the shangdong of the shaft 131 of the width adjusting means 130 has a ring or a crane in the width adjusting ring 136 formed at the bottom of the movable ring 140 and the disc 135 at the top of the width adjusting means 130. This can be done by hanging 200 and pulling it from the outside. Specifically, the hook (200) hangs the crane 200 to raise the width adjusting means 130 to the upper side, and the width adjusting ring 136 is fixed to the bottom surface to hang the outer ring formed to be pulled from the lower side. It is good.
