Device for prevention buckling of workpiece in break down mill

강편 조압연기의 소재 버클링 방지장치

Abstract

본 발명은 강편 조압연기의 소재 버클링 방지장치에 관한 것으로, 선재 조압연기의 롤네크 일단에 인접하여 일체로 형성된 기준원판과; 상기 기준원판보다 작은 직경을 갖고 그로부터 연장된 스플라인과; 상기 스플라인보다 작은 직경을 갖고 롤네크 타단을 향해 연장되며 그 외주면에 그 축방향 및 주연방향으로 직교되게 요입형성된 고정키홈 및 체결홈을 갖는 원통고정부와; 상기 고정키홈과 대응되는 고정판내측키홈이 그 내주면에 형성되어 고정판고정키에 의해 고정되고, 그 외주면에는 다수의 고정판외측키홈이 형성되며, 상기 원통고정부에 끼워져 고정되는 고정판과; 상기 고정판의 일측면과 접촉배치되고 고정판고정키에 의해 동시 고정되며, 그 외주면에는 나사산이 형성된 로킹링과; 상기 로킹링의 외주면에 나합되고, 그 외주면에는 상기 고정판외측키홈과 대응되는 어저스트링외측키홈을 가져 외측고정키에 의해 동시 키고정되는 어저스트링과; 상기 로킹링이 이탈되지 않도록 상기 원통고정부의 체결홈에 끼워 고정되는 하프링을 포함하여 구성된다. 본 발명은 규격화되고 정형화되며 항상 일정한 롤 캘리버를 갖는 플랜지롤을 교체, 제공할 수 있으므로 소재의 버클링현상이 제거되며, 이로 인해 제품의 품위가 현격히 향상된다.
To provide a device for removing roll caliber and sequentially assembling flange rolls for always constantly maintaining the roll caliber instead to remove buckling of workpiece, safely maintain the workpiece in the finish rolling process and reduce cost due to roll processing and improve productivity accordingly since turning operation of roll is not necessary. The device for preventing buckling of workpiece in break down mill comprises a reference disk(110) integrally formed adjacently to one end of a roll neck(100) of wire rod roughing mill; a spline(120) which has diameter smaller than that of the reference disk and is extended from the reference disk; a cylindrical fixing part which has diameter smaller than that of the spline and is extended toward the other end of the roll neck, and on the outer circumferential surface of which a fixing key groove and a clamping groove are indented perpendicularly to axial and circumferential directions of the cylindrical fixing part; a fixed plate(200) on the inner circumferential surface of which a fixed plate inner key groove corresponding to the fixing key groove is formed such that the fixed plate inner key groove is fixed by a fixed plate fixing key(240), on the outer circumferential surface of which a plurality of fixed plate outer key groove is formed, and which is fixed with being inserted into the cylindrical fixing part; a locking ring(250) which is disposed such that it is contacted with one surface of the fixed plate, which is fixed by the fixed plate fixing key at the same time, and on the outer circumferential surface of which a screw thread is formed; an adjust ring(260) which is screw connected to the outer circumferential surface of the locking ring, and on the outer circumferential surface of which an adjust ring outer key groove corresponding to the fixed plate outer key groove is formed so that the adjust ring outer key groove is fixed by an outer fixing key(270) at the same time; and a half ring(300) fixed with being inserted into the clamping groove of the cylindrical fixing part such that the locking ring is not separated.
