본 발명은 박판 스트립을 코일형태로 감아서 이송하여 최종공정에서 수요가가 요구하는 폭과 중량으로 단중을 분할하는 작업을 할 때에 내경부에서 발생되는 판 처짐 현상을 자동적으로 보완하기 위한 맨드릴에 장착되는 코일 내경부 판처짐 방지기에 관한 것이다.The present invention is mounted on the mandrel to automatically compensate for the deflection of the plate generated in the inner diameter when the thin strip is wound in the form of a coil and transported to divide the load into the width and weight required by the demand in the final process It relates to a coil inner diameter deflection preventer.

도 1은 종래의 맨드릴에서 코일 내경부 판처짐 예를 보인 예시도로서, 박판코일(1)의 내부에 맨드릴(2)을 삽입하고자 할 때에 박판코일(1)의 내부에 판처짐(3) 현상이 발생하면 맨드릴(2)의 삽입이 용이하지 못하게 되며, 코일 내경부에 위치한 판 처짐부(3)를 작업자가 직접 손으로 고정시킨 후 코일카(4)를 전진시켜 맨드릴(2)에 삽입시켜 작업하여 왔다.FIG. 1 is an exemplary view showing an example of internal bending of a coil in a mandrel of the related art, in which a plate deflection (3) is developed inside a thin plate coil 1 when a mandrel 2 is inserted into the thin plate coil 1. If this occurs, the insertion of the mandrel (2) is not easy, and the operator directly fixed the plate deflection (3) located in the inner diameter of the coil by hand, and then advance the coil car (4) to insert into the mandrel (2) I've been working.

일반적으로 맨드릴의 구조는 도 2에서 보는 바와 같이 다수개의 세그멘트로 이루어지며 세그멘트 내부에는 웨지경사부가 가공되어 작동실린더(13)의 작동에 의하여 작동축(23)의 왕복운동에 의해 밀려나가면 수축(5)되고 안으로 들어오면 확장(8)되는 구조를 취한다. 이 때 안내가이드(9)는 다수개의 세그멘트부를 안내하여 이탈됨을 예방하게 된다.In general, the structure of the mandrel is composed of a plurality of segments as shown in Figure 2 and the wedge inclined portion is processed inside the segment is pushed out by the reciprocating motion of the operating shaft 23 by the operation of the operating cylinder (13) contraction (5) And when it enters in, it expands (8). At this time, the guide guide 9 guides a plurality of segments to prevent them from being separated.

상기 작동축(23)은 그 일단에 볼 죠인트(10)가 설치되고 그 외접부에는 기어 가공부를 두고 있어, 하단에 위치한 피니언기어(11)부와 서로 맞물리어 모터(12)로부터 회전력을 전달 받아 맨드릴(2)을 회전시키게 되며, 실린더(13)에 의하여 이러 한 장치들은 고정베이스(14)에 고정된다.The working shaft 23 is provided with a ball joint 10 at one end thereof, and has a gear processing portion at its outer portion, and receives a rotational force from the motor 12 in engagement with the pinion gear 11 portion located at the bottom thereof.

This insert is installed.

이와 같은 맨드릴(2)에 판 처짐부(3)를 삽입시키기 위해서는 코일 내경부에 위치한 판 처짐부(3)를 작업자가 직접 손으로 고정시킨 후 코일카(4)를 전진시켜 맨드릴(2)에 삽입시켜 작업하여 왔다.In order to insert the plate deflection 3 into the mandrel 2, the operator directly fixes the plate deflection 3 located on the inner diameter of the coil by hand, and then advances the coil car 4 to the mandrel 2. Work has been done by inserting.

그러나 이와 같은 작업방법은 매 코일 작업시 마다 작업자가 직접 판 처짐부(3)를 작업자가 고정시켜야 하는 번거로움과 함께, 코일카(4)로부터 코일 전도 사고 및 손가락 협착 사고에 위험이 항시 존재하여 왔다.  However, such a work method, along with the trouble that the operator has to fix the plate deflection part 3 manually at every coil work, there is always a risk of coil conduction accident and finger stenosis accident from the coil car (4). come.

본 발명은 상기와 같은 종래의 문제점을 감안하여 안출된 것으로서, 맨드릴 전면부에 원뿔대형 판 처짐부 유도장치를 장착하여, 맨드릴 수축 시 모아지고, 확장시 펼쳐져서 판 처짐부를 받쳐 올려 구겨짐 없이 자동으로 판 처짐부를 안내하고, 정상작업시 코일이 맨드릴 전면으로 빠져 나오는 현상을 예방하기 위한 맨드릴에 장착되는 코일 내경부 판처짐 방지기를 제공하는 데 그 목적이 있다.The present invention has been made in view of the above-described conventional problems, equipped with a truncated conical plate deflection portion induction device on the mandrel front part, is collected when the mandrel contracts, is expanded during expansion to support the deflection plate plate up automatically without wrinkles It is an object of the present invention to provide a coil inner diameter deflection preventer mounted on a mandrel for guiding a plate deflection and preventing a coil from falling out of the front of the mandrel during normal operation.

이하, 도면을 참조하여 본 발명에 대하여 상세하게 설명한다.EMBODIMENT OF THE INVENTION Hereinafter, this invention is demonstrated in detail with reference to drawings.

도 3은 본 발명 장치의 내부가 보이게 한 사시도이고, 도 4는 단면도이다.3 is a perspective view showing the inside of the apparatus of the present invention, Figure 4 is a cross-sectional view.

본 발명의 구성은 맨드릴(2)의 일단의 고정 플레이트(6)의 원주 가장자리에 체결되는 다수개의 원뿔대형 박판 유도부(18)가 곡선 설치 핀(26)에 의해 설치되고, 박판유도부(18) 표면에는 다수개의 볼(17)이 결합되어 마찰력을 감소하게 된다.In the configuration of the present invention, a plurality of truncated conical plate guides 18 fastened to the circumferential edges of the fixed plate 6 of one end of the mandrel 2 are installed by the curved installation pins 26, and the surface of the thin plate guide part 18 is provided. There are a plurality of balls 17 are combined to reduce the friction force.

상기 이탈 방지턱(7) 연장선상에는 왕복 축(20)이 연장되며, 왕복 축(20) 외접부에는 다수개의 연결링크(19)부가 박판 유도부(18) 내접부와 견인되어진다.The reciprocating shaft 20 extends on the separation prevention jaw 7 extension line, and a plurality of connection links 19 are pulled to the inner guiding portion of the thin plate guide 18 on the circumferential portion of the reciprocating shaft 20.

상기 박판 유도부(18) 상단에는 연결고리(24)가 형성되어 서로 이탈됨이 없이 유동성 있게 체결되는 연결 핀(25)이 심어지며, 작동축(23)이 전후로 왕복됨에 따라 박판 유도부(18)의 외경이 가변되는 형태를 취한다. The connecting ring 25 is formed on the upper end of the thin plate induction part 18 so that the coupling pin 25 is fluidly fastened without being separated from each other, and as the operating shaft 23 is reciprocated back and forth, Take the form of varying the outer diameter.                     

이와 같이 구성되는 본 발명의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention configured as described above are as follows.

상기 박판코일(1)의 내경부에 판 처짐부(3) 발생시 상기 맨드릴(2)을 수축하기 위해서는 작동축(23)이 바깥으로 전진되어 있는 왕복축(20)을 밀치게 되면 연결링크(19)가 수평위치에서 접혀지면서 박판유도부(18)를 내측으로 당기면서 원뿔대 형태를 취한다.In order to contract the mandrel 2 when the plate deflection portion 3 occurs in the inner diameter of the thin plate coil 1, when the operating shaft 23 pushes the reciprocating shaft 20 forward, the connecting link 19 ) Is pulled in a horizontal position and takes the form of a truncated cone while pulling the plate induction part 18 inward.

위와 같이 좁혀진 박판유도부(18)가 박판코일(1) 내경부에 처져있는 판 처짐부(3)를 밀착시켜 맨드릴(2)에 삽입시 판 처짐부(3)가 심하게 구겨지는 현상을 예방하고, 상기 박판유도부(18)의 외접부에 박혀있는 다수 개의 볼(17)부는 판 처짐부(3)와 접촉시 구름운동을 실시하여 마찰력 최소와 진원 유지와 내경부 스크랩발생을 근본적으로 예방하는 효과를 부여하게 된다.The thin plate guide portion 18 narrowed as described above closely adheres to the plate deflection portion 3 sagging in the inner diameter of the thin plate coil 1, thereby preventing the plate sag portion 3 from being severely wrinkled when inserted into the mandrel 2. The plurality of balls 17 embedded in the outer portion of the thin plate induction part 18 performs a rolling motion when contacting the plate deflection part 3 to fundamentally prevent the minimum frictional force, maintain the roundness, and prevent the occurrence of internal diameter scraps. Will be given.

본 발명은 상기와 같이 맨드릴 전면부에 원뿔대형 판 처짐부 유도장치를 장착시켜, 맨드릴 수축 시 모아지고, 확장시 펼쳐져 판처짐부를 받쳐 올려 구겨짐 없이 자동으로 박판 처짐부를 안내하고, 정상작업시 코일이 맨드릴 전면으로 빠져 나오는 현상을 예방하여 스크랩 방지와 생산장애 시간을 획기적으로 줄이는 효과를 부여하게 된다.The present invention is equipped with a truncated conical plate deflection part induction device on the front surface of the mandrel as described above, is collected when the mandrel shrinks, expands during expansion to support the plate deflection portion and guides the sheet deflection automatically without wrinkling, and the coil in normal operation It prevents the drooping out of the front of the mandrel, which gives the effect of preventing scrap and dramatically reducing downtime.
