Abstract

The present invention relates to a bending device for bending a metal plate and, to a bending device for bending a metal plate comprising: a roller mounting part formed on the bent surface (S) of a metal plate of a mold for bending the metal plate, and formed to mount a rotation roller; and the rotation roller formed to be exposed by being higher than the bent surface when the rotation roller is mounted, Moreover, the roller mounting part is formed to insert and mount the rotation roller in the longitudinal direction of the mold, and to separate the inserted rotation roller in the longitudinal direction of the mold. While the metal plate, which is an object, is bent inside the mold for bending the metal plate by being pressed from an upper part, the metal plate is formed on the bent surface (S) of the metal plate, so the metal plate is In contact with the rotation roller mounted on and inserted into the roller mounting part. Therefore, a scratch is not generated on the surface of the metal plate. Even if a scratch is generated by increasing the applied pressure, the scratch is completely removed by a mild secondary process. Moreover, a bending process is quickly performed by the rotation of the rotation roller, the working speed is significantly increased, so the time and costs are saved.

Description

절곡 금속판재용 절곡장치{Bending device for metal plate}Technical Field [0001] The present invention relates to a bending device for a metal plate,

본 발명은 절곡 금속판재용 절곡장치에 관한 것으로, 더욱 상세하게는 각종 산업현장에서 다양한 용도로 사용하는 절곡된 금속부재(예컨대, 철근, 봉재, 선재, 강재 등)를 상호 동시에 절곡시킬 수 있게 함과 아울러 절곡되는 금속부재의 폭에 상관없이 모두 절곡할 수있게 하여 사용상에 편리한 절곡 금속판재용 절곡장치에 관한 것이다.
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bending device for a bending metal plate, and more particularly to a bending device for bending a metal member (for example, a reinforcing bar, a bar, a wire, The present invention also relates to a bending apparatus for a bending metal plate, which can be easily bent regardless of the width of a metal member to be bent.

일반적으로 건축이나 토목 공사장, 기계장치등 각종 산업현장에서 사용되는 금속재 판재는 일정한 길이를 갖는 소정 모양으로 절곡하여 사용하게 된다. 즉, 상기 금속재 판재를“V", "ㄷ", "U", "ㄱ”자 를 포함한 다양한 형상으로 절곡시켜 사용하게 된다.Generally, a metal plate used in various industrial sites such as an architecture, a civil engineering site, and a mechanical device is bent into a predetermined shape having a predetermined length. That is, the metal plate is bent into various shapes including "V", "C", "U", and "A".

그러나, 절곡된 금속 판재의 표면에는 절곡시에 불필요하게 절곡장치부터 스크래치(흠)가 발생하게 되어, 다시 상기 스크래치를 제거하는 작업을 다시 수행하게 되어, 작업속도가 상당히 지연하게 되는 문제점이 발생하게 되며, 한번 발생된 스크래치는 절곡표면으로부터 완전히 제거하기 어려우며, 이로 인하여, 스크래치로부터 녹이 형성되어, 장기간 사용시에 제품 전체적으로 불량이 발생하게 되어, 교체작업을 하여야 하는 문제점이 발생된다.
However, the surface of the bent metal plate is unnecessarily bent from the bending device to scratches (blemishes) at the time of bending, and the operation of removing the scratches again is performed again, thereby causing a problem that the working speed is significantly delayed And the scratches generated once are difficult to completely remove from the bending surface. As a result, rust is formed from the scratches, resulting in defective products throughout the use for a long period of time, thus requiring replacement work.

도 1은 종래의 절곡 금속판재용 절곡장치를 나타낸 개략도이고, 도 2는 본 발명의 일실시예에 따른 절곡 금속판재용 절곡장치를 나타낸 개략도이고, 도 3은 본 발명의 일실시예에 따른 절곡 금속판재용 절곡장치를 나타낸 입체도이다.2 is a schematic view showing a bending apparatus for a bending metal plate according to an embodiment of the present invention, and FIG. 3 is a schematic view of a bending apparatus for a bending metal plate according to an embodiment of the present invention. Fig.

도 1에 도시한 바와 같이, 도 1은 종래의 절곡 금속판재용 절곡장치를 나타낸 개략도로서, 종래의 절곡 금속판재용 절곡장치는 금속판재 절곡용 금형(20) 상부에 대상물인 금속판재를 위치시키고, 상부에서 가압하여 금형의 형상에 의하여 금속판재가 절곡되는 구성으로 이루어진다. 1 is a schematic view of a conventional folding apparatus for a bending metal plate. In the conventional bending apparatus for a bending metal plate, a metal plate as an object is placed on a metal plate bending die 20, And the metal plate is bent by the shape of the metal mold.

이는 금속판재가 금형내부로 절곡되면서, 금속의 절곡면에 접촉되어 절곡되면서, 금속판재의 표면에 불필요한 스크래치가 깊이 형성되는 것이다. 이러한 스크래치는 시간이 경과하면서, 녹이 발생되는 요인이 되어 제품을 불량하게 만들며, 제품의 가치를 감소시키며, 수명을 감소시키는 것이다. 그러므로, 절곡된 판재는 불필요한 2차 표면가공을 행하여야하며, 시간과 비용이 발생하게 되며, 한번 발생된 스크래치는 깊이 형성되어, 2차가공을 수행하더라도 원래 상태의 표면으로 회복하기 어려운 문제점이 발생되는 것이다.This is because the metal plate material is bent into the metal mold and is folded in contact with the bent surface of the metal so that unnecessary scratches are formed deeply on the surface of the metal plate material. Such scratches, over time, cause rusting, which makes the product poor, reduces the value of the product, and reduces its service life. Therefore, the bent plate needs to perform an unnecessary secondary surface processing, and time and cost are incurred, and once the scratches are formed, the problem is difficult to recover to the original surface even if the secondary processing is performed .

도 2는 본 발명의 일실시예에 따른 절곡 금속판재용 절곡장치를 나타낸 개략도로서, 이를 상세히 설명하면 다음과 같다.FIG. 2 is a schematic view showing a bending apparatus for a bending metal plate according to an embodiment of the present invention, which will be described in detail as follows.

본 발명은 금속판재 절곡장치에 있어서, 금속판재 절곡용 금형(20)의 금속판재 절곡표면(S)에 형성되어 회전롤러(30a)가 안착되도록 형성된 롤러안착부(30)와; 상기 회전롤러(30a)는 안착시에 절곡표면(S)보다 높게 노출되도록 이루어 진 절곡 금속판재용 절곡장치에 관한 것이다.The present invention relates to a metal sheet bending apparatus, comprising: a roller seating part (30) formed on a metal sheet bending surface (S) of a metal sheet bending die (20) and adapted to receive a rotary roller (30a); And the rotating roller 30a is exposed to be higher than the bending surface S at the time of seating.

도 2에 나타난 바와 같이, 대상물인 금속판재는 상부로부터 가압되어 금속판재 절곡용 금형(20)내부로 절곡되면서, 금속판재 절곡표면(S)에 형성되어 롤러안착부(30) 안착 삽입된 회전롤러(30a)와 상호 접촉되는 것이다. 이로 인하여 금속판재의 표면에는 스크래치가 발생되지 않으며, 만약 가압력의 증가에 의하여 스크래치가 발생되더라도, 가벼운 2차가공에 의하여 스크래치는 완전히 제거되는 것이다. As shown in FIG. 2, the metal plate material as the object is pressed from the upper part and bent into the metal plate bending die 20, and is formed on the metal plate bending surface S and is inserted into the roller seat 30 30a. As a result, no scratch is generated on the surface of the metal plate, and even if scratches are generated due to the increase of the pressing force, the scratches are completely removed by the light secondary processing.

또한, 회전롤러(30a)의 회전에 의하여 절곡가공작업이 신속히 수행되어, 작업속도도 상당히 증가되어, 시간과 비용이 절감되는 것이다.In addition, the rotation of the rotary roller 30a allows the bending operation to be performed quickly, and the operation speed is significantly increased, thereby saving time and cost.

도 3은 본 발명의 일실시예에 따른 절곡 금속판재용 절곡장치를 나타낸 입체도로서, 본 발명의 절곡 금속판재용 절곡장치의 양단에 상기 회전롤러(30a)가 안착시에 절곡장치로부터 이탈되지 않도록 롤러이탈방지부(40)를 부가한 것을 특징으로 하는 것이다.FIG. 3 is a perspective view of a bending apparatus for a bending metal plate according to an embodiment of the present invention. When the bending apparatus for a bending metal plate according to the present invention is used, (40) is additionally provided.

금속판재 절곡용 금형(20)의 금속판재 절곡표면(S)에 형성되어 있는 회전롤러(30a)는 금형(20)의 길이방향만으로 삽입되어 안착시키며, 삽입된 회전롤러(30a)는 금형(20)의 길이방향으로만 이탈되도록 롤러안착부(30)를 금형표면에 형성시켜, 작업중이거나, 위치 이동중에 회전롤러(30a)가 쉽게 이탈되지 않도록 하는 것이다.The rotating roller 30a formed on the metal sheet bending surface S of the metal sheet bending die 20 is inserted and seated only in the longitudinal direction of the metal mold 20 and the inserted rotating roller 30a is inserted into the mold 20 The roller seating portion 30 is formed on the surface of the mold so that the rotary roller 30a can not be easily removed during operation or positional movement.

삽입 안착된 회전롤러(30a)는 금형으로부터 이탈되지 않도록 금형(20)의 양단에 롤러이탈방지부(40)를 부가시키는 것을 특징으로 한다.
And the roller separation preventing portion 40 is attached to both ends of the mold 20 so that the rotating roller 30a inserted and seated is not separated from the mold.
