Description

강판 표면 연마장치Steel plate surface grinding device
본 발명은 강판 표면 연마장치에 관한 것으로, 보다 상세하게는 강판의 표면을 연마하는데 사용되는 강판 표면 연마장치에 관한 것이다.The present invention relates to a surface polishing apparatus for a steel sheet, and more particularly, to a surface polishing apparatus for a steel sheet used for polishing the surface of a steel sheet.
스테인레스 스틸판과 같은 금속판의 표면에 미세한 헤어라인과 같은 스크래치패턴을 형성하면 금속 고유의 광택을 유지하면서도 고급스러운 장식효과를 얻을 수 있고, 아울러 내지문 효과, 즉 손자국 방지효과를 얻을 수 있어서, 이러한 헤어라인 가공방법은 스테인레스스틸판과 같은 금속판의 표면가공방법으로 널리 사용되고 있다.If a scratch pattern such as a fine hairline is formed on the surface of a metal plate such as a stainless steel plate, a luxurious decorative effect can be obtained while maintaining the inherent luster of the metal, and an anti-fingerprint effect, that is, a handprint prevention effect can be obtained. The hairline processing method is widely used as a surface processing method of a metal plate such as a stainless steel plate.
종래의 이러한 금속판에 헤어라인을 형성하는 장치들은 대체로 코일로부터 연속적으로 풀려나오는 코일강판이나 소정의 길이로 절단된 강판시트의 위에 샌드페이퍼가 감긴 연마벨트나 연마패드가 코일강판이나 강판시트의 공급 또는 이송방향을 따라 회전 또는 왕복하면서 금속판에 스크래치를 형성하여 헤어라인을 형성하게 된다. 그런데, 이러한 종래의 헤어라인 형성장치는 공급되는 코일강판 또는 소정길이로 절단된 강판시트의 길이방향을 따라 헤어라인을 형성하기 때문에, 코일강판 또는 강판시트의 가로방향을 따라 헤어라인을 형성하기 곤란하였다.In the conventional apparatus for forming a hairline on such a metal plate, an abrasive belt or abrasive pad wound with sandpaper on a coiled steel plate continuously released from a coil or a steel plate cut to a predetermined length is supplied or transported. The hairline is formed by forming scratches on the metal plate while rotating or reciprocating along the direction. However, since this conventional hairline forming apparatus forms a hairline along the longitudinal direction of the supplied coiled steel sheet or the steel sheet cut to a predetermined length, it is difficult to form a hairline along the transverse direction of the coiled steel sheet or steel sheet. did.
따라서, 종래에는 주로 코일 또는 시트의 길이방향을 따라 줄무늬가 형성되는 길이방향 헤어라인 패턴의 제품이 공급되었으며, 코일강판 또는 시트상의 강판의 가로방향을 따라 줄무늬가 형성되는 가로방향 헤어라인 패턴을 자동으로 형성하는 컴팩트하고 효율적인 장치는 제공되지 않고 있다.Therefore, conventionally, products of a longitudinal hairline pattern in which stripes are formed along the longitudinal direction of a coil or sheet have been mainly supplied, and a transverse hairline pattern in which stripes are formed along the transverse direction of a steel plate on a coil or sheet is automatically produced. A compact and efficient device formed by
특히, 코일강판으로부터 연속적으로 풀려나오는 금속판과 소정길이로 절단되어 공급되는 강판시트 양자 모두를 가로방향으로 헤어라인을 형성할 수 있는 효율적이고 컴팩트한 장치가 아직 알려져 있지 않다. 따라서 종래의 헤어라인 제품은 주로 길이방향 줄무늬패턴을 가진 헤어라인 제품이 주종을 이루었고, 새롭고 참신한 미감을 주는 가로방향 헤어라인 제품은 양산되지 못하는 실정이다.In particular, an efficient and compact device capable of forming a hairline in the transverse direction for both a metal plate continuously released from a coiled steel plate and a steel plate sheet cut to a predetermined length and supplied has not been known yet. Therefore, the conventional hairline products mainly consist of hairline products having a longitudinal stripe pattern, and horizontal hairline products giving a new and novel aesthetic cannot be mass-produced.
또한, 종래의 헤어라인 성형장치는 대체로 하나의 장치유닛에 하나의 연마벨트 또는 연마패드가 설치되는 구조를 취하므로, 헤어라인의 스크래치의 굵기가 서로 다른 복수 종류의 헤어라인을 단일의 금속판에 형성하는 복합무늬 헤어라인을 형성하기 위해서는 형성하기 위해서는 다수의 헤어라인 성형장치을 배치하여 가공해야 하므로, 다수의 헤어라인장치가 필요하므로, 그 만큼 장치가 복잡하고 공간을 많이 차지하는 문제점이 있었다.In addition, since the conventional hairline forming apparatus generally has a structure in which one polishing belt or a polishing pad is installed in one device unit, a plurality of types of hairlines having different thicknesses of hairline scratches are formed on a single metal plate. In order to form a hairline with a complex pattern, it is necessary to arrange and process a plurality of hairline forming apparatuses in order to form the hairline, and thus a plurality of hairline apparatuses are required.

예컨대, 상기 연마수단(220)은 회동 각도가 45도인 경우, 상기 이송 벨트(113)와 사선 방향으로 위치되므로, 상기 연마수단(220)이 0도의 회동 각도에서 상기 이송 벨트(113)와 접촉되는 면적보다 더 크다.For example, when the rotation angle of the grinding means 220 is 45 degrees, since the grinding means 220 is positioned in an oblique direction with the transfer belt 113, the grinding means 220 is in contact with the transfer belt 113 at a rotation angle of 0 degrees. larger than the area.
따라서, 상기 연마수단(220)의 회동 각에 따라 연마 벨트(228)의 최하단 길이를 조절하여 상기 이송 벨트(113)와 접촉되는 면적이 동일하도록 하는 것이 바람직하다.Therefore, it is preferable to adjust the length of the lowermost end of the polishing belt 228 according to the rotation angle of the polishing means 220 so that the area in contact with the conveying belt 113 is the same.
여기서, 상기 연마수단(220)이 상기 이송 벨트(113)와 직교하는 방향에 위치 시 회동 각도는 0도를 이루며, 상기 연마 벨트(228)의 접촉 면접이 비교적 짧아진다.Here, when the grinding means 220 is positioned in a direction perpendicular to the conveying belt 113, the rotation angle is 0 degrees, and the contact surface of the abrasive belt 228 is relatively short.
이에 따라, 상기 연마 벨트(228)는 상기 연마수단(220)의 회동 각도에 따라 상기 수평 롤러(226) 및 수직 롤러(227)를 통해 최하단의 길이를 조절함으로써, 최적의 연마 면적을 제공한다.Accordingly, the polishing belt 228 provides an optimal polishing area by adjusting the length of the lowermost end through the horizontal roller 226 and the vertical roller 227 according to the rotation angle of the polishing means 220 .
이러한 구성으로, 상기 연마수단(220)은 회동에 따라 상기 강판(10)에 가로 방향의 헤어라인 뿐만 아니라, 0~45도 사이의 사선 방향의 헤어라인도 연마할 수 있다.With this configuration, the polishing means 220 can grind not only the hairline in the horizontal direction on the steel plate 10 but also the hairline in the oblique direction between 0 and 45 degrees according to the rotation.
본 발명에 의한 강판 표면 연마장치에 따르면, 컨베이어에 연마수단이 회동 가능하게 결합됨으로써, 연마수단의 회동을 통해 연마 각도를 조절하여 강판 표면에 다양한 패턴을 연마할 수 있는 효과를 얻을 수 있다.According to the steel plate surface polishing apparatus according to the present invention, since the grinding means is rotatably coupled to the conveyor, it is possible to obtain the effect of grinding various patterns on the surface of the steel plate by adjusting the grinding angle through the rotation of the grinding means.
특히, 하나의 연마수단의 각도 조절에 따라 다양한 패턴을 연마함으로써, 설비 단순화 및 소형화에 따른 설비 구축 비용을 절감할 수 있는 효과를 얻을 수 있다.In particular, by grinding various patterns according to the angle adjustment of one grinding means, it is possible to obtain the effect of reducing equipment construction costs due to equipment simplification and miniaturization.
또한, 서로 대칭되는 연마수단을 구비함으로써, 더욱더 다양한 패턴을 연마할 수 있는 효과를 얻을 수 있다.In addition, by providing the polishing means symmetrical to each other, it is possible to obtain the effect of polishing more various patterns.
