미세 타공판{micro-perforated plate}Micro-perforated plate

본 발명은 금속판재에 미세한 구멍을 연속적으로 타공하여 소음을 흡수 분산하는 데 사용하는 미세 타공판에 관한 것으로, 더욱 구체적으로는 일정 단위면적 당 미세구멍을 최대로 형성하면서 구멍의 타공시에 발생되는 돌출편을 다양한 모양으로 무수히 형성하여 접촉면적을 확장함으로써 소음의 흡수 및 분산 효과를 효율적으로 증가시켜 각종 건축자재, 자동차 부품, 전자기기 부품 등으로 다양하게 사용할 수 있도록 한 미세 타공판에 관한 것이다. The present invention relates to a fine perforated plate used to continuously perforate fine holes in a metal plate material to absorb and disperse noise. More specifically, the present invention relates to protrusions generated during perforation of holes while maximally forming fine holes per predetermined unit area. The present invention relates to a microperforated plate that can be used in various building materials, automobile parts, and electronic device parts by efficiently increasing the absorbing and dispersing effect of noise by forming numerous pieces in various shapes and expanding the contact area.

현대를 살아가는 사람들은 일상생활에서 주변의 여러 환경 요소에 따라 다양하고 많은 종류의 소음에 노출되어 있고 이러한 소음들로 하여금 스트레스를 받게 되므로서 건강을 해치는 등 삶의 질이 나빠지고 있음은 주지의 사실이다.        It is well known that people living in modern times are exposed to various and various kinds of noises according to various environmental factors in their daily lives, and that these noises are stressed and their quality of life is deteriorated. to be.

이러한 문제의 해소를 위해 각종 흡음 및 방음 그리고 차음시설이 시설물과 자동차, 전자기기등에 사용되고 있는 바, 예를 들어 극장, 음악실, 녹음실 등에서는 소음이 외부로 전달되거나 내부로 유입되는 것을 차단하고 소리에 의한 음향의 반사로 발생되는 공진현상을 제거하기 위해 흡음 및 방음설비를 구비하고 있으며, 이러한 흡음설비는 자동차를 비롯하여 휴대폰과 같은 전자기기에도 사용되고 있다.       To solve this problem, various sound absorbing, soundproofing, and soundproofing facilities are used in facilities, automobiles, and electronic devices. For example, in theaters, music rooms, and recording studios, noise is prevented from being transmitted to the outside or introduced into the interior. Sound absorption and soundproof facilities are provided to remove resonance caused by the reflection of sound caused by the sound. Such sound absorption facilities are used in electronic devices such as automobiles and mobile phones.

일반적으로 흡음재는 건축물에 사용되는 암면, 글라스울을 포함하여 합성수지를 성형한 흡음보드, 우레탄 소재로 만든 흡음판이 있으며, 또 무수한 구멍을 뚫은 타공판이 흡음재로서 많이 사용되고 있다.       In general, sound absorbing materials include sound absorbing boards made of synthetic resin including glass wool and glass wool, and sound absorbing plates made of urethane, and perforated plates with numerous holes are widely used as sound absorbing materials.

이러한 타공판은 무수한 구멍으로 인해 소리 즉 음파가 고속으로 작은 구멍을 통과하면서 산란되고 구멍의 내부에 붙게 되는 과정에서 분자의 마찰 작용으로 인해 열에너지로 전환하면서 소리가 작아지게 되어 흡음효과를 얻을 수 있게 되는 것으로 저주파 또는 고주파 대역의 흡음은 구멍의 크기와 갯수 및 깊이 등에 의해 좌우된다.       The perforated plate is sounded due to a myriad of holes, so that sound waves are scattered as they pass through small holes at high speed and are stuck inside the holes. Absorption of the low frequency or high frequency band depends on the size, number and depth of holes.

한편 미세한 구멍을 타공한 미세 타공판은 각종 건축자재 뿐 아니라 근래에는 자동차의 진동에 따른 소음을 해소하기 위한 흡음소재로서 사용되고 있고 또 휴대폰과 같은 전자기기에도 금속박판에 미세공을 타공한 미세타공판이 사용되어 진동과 흡음을 감소시키는 용도로 사용되고 있다.       On the other hand, the fine perforated plate with fine holes is used as a sound absorbing material to solve the noise caused by the vibration of the automobile as well as various building materials.In addition, the fine perforated plate perforated fine metal plate is used for the electronic devices such as mobile phones. It is used for the purpose of reducing vibration and sound absorption.

그러나 종래에 사용되는 흡음판은 금속판재나 또는 박판에 단순히 구멍을 뚫어 형성한 것으로 음파의 접촉면적이 적어 흡음효율이 우수하지 않는 단점이 있었다.       However, a conventional sound absorbing plate is formed by simply punching a hole in a metal plate or a thin plate, and has a disadvantage in that sound absorption efficiency is not excellent due to a small contact area of sound waves.

본 발명의 목적은 상기한 점을 감안하여 안출한 것으로 금속판재에 미세공을 단위 면적 당 최대한 많게 형성하되 미세공을 천공하면서 발생되는 돌출편의 형상을 다양한 형상으로 형성하여 소리의 접촉면적을 증가시키므로서 흡음율을 향상시킬 수 있는 미세 타공판을 제공하는 데 있다. The object of the present invention is to devise in view of the above point to form as many fine pores per unit area in the metal plate as possible, but to form the shape of the protruding pieces generated while drilling the micropores in various shapes to increase the contact area of the sound The present invention provides a fine perforated plate capable of improving sound absorption.

본 발명은 이와같은 목적을 달성하기 위한 수단으로, 미세 타공판에 있어서, 흡음공이 양쪽으로 나란히 미세한 길이로서 천공 절개되어 형성되고 그 사이에 가압력에 의해 함몰되어 이루어진 사다리꼴 형상의 돌출편이 형성되어 한개의 돌출편에 양쪽으로 관통된 2개 1조의 흡음공이 형성되어 이루어짐을 특징으로 하는 미세 타공판을 제공한다. The present invention is a means for achieving the above object, in the fine perforated plate, the sound-absorbing hole is formed by cutting the perforated side by side in fine lengths on both sides, and the trapezoidal protrusions formed by being depressed by the pressing force therebetween to form a single protrusion It provides a fine perforated plate characterized in that the two pieces of sound-absorbing holes penetrated to both sides formed on one side.

상기, 돌출편은 알루미늄이나 스틸, 스테인레스, 티타늄, 동, 등으로 이루어진 금속판재에 일정한 방향으로 간격을 두고 돌출되어 격자상으로 연속 배열 형성되어 이루어짐을 특징으로 한다. The protruding pieces are characterized in that the protruding pieces are made of aluminum or steel, stainless, titanium, copper, or the like and protrude at intervals in a predetermined direction to form a continuous array in a lattice form.

상기, 돌출편은 측면에서 볼 때 경사지게 형성되어 흡음공의 크기가 다르게 형성된 것을 특징으로 한다. The protrusion is inclined when viewed from the side, characterized in that the size of the sound absorbing hole is formed differently.

상기, 돌출편은 상면이 호형의 곡면으로 이루어지고 평면에서 보면 부채꼴 형상을 이루어 한쪽의 흡음공은 다른 쪽의 흡음공에 비해 적게 형성됨을 특징으로 한다. The protruding piece is characterized in that the upper surface is formed of an arc-shaped curved surface, and when viewed in a plane, a fan-shaped shape is formed so that one sound absorbing hole is formed less than the other sound absorbing hole.

상기, 돌출편은 삼각형상으로 이루어짐을 특징으로 한다. The protruding piece is made of a triangular shape.

상기, 돌출편은 지그재그로 형성됨을 특징으로 한다. The protruding pieces are zigzag.

이와같은 본 발명에 따르면, 종이와 같이 얇은 박판에 무수한 타공을 형성함에 있어 상단이 날카로운 뿔기둥을 교차되는 경사홈에 의해 형성한 타공로울러에 의해 연속적으로 타공하여 형성하게 되므로 타공작업이 매우 용이하고 효율적인 타공을 할 수 있을 뿐 아니라 타공침이 상형하광한 뿔기둥의 형태로서 매우 안정적이므로 타공침이 종래와 같이 쉽게 파손되지 않아 경제적이고 우수한 품질의 타공 박판시트를 제공할 수 있는 효과가 있다. According to the present invention, in forming a myriad of perforations in thin sheets such as paper, the perforation work is very easy because perforated rollers are formed continuously by perforated rollers formed by inclined grooves intersecting the sharp horn pillars. Not only can the efficient perforation but also the piercing needle is very stable in the form of a horn column with a flat-bottomed horn, so that the piercing needle is not easily broken as in the prior art, thereby providing an economical and excellent quality thin sheet sheet.

이하, 본 발명의 실시예를 첨부한 도면을 참조하여 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명에 따른 일 실시예의 일부 확대 예시 사시도로서, 본 발명의 타공판(100)에 형성된 흡음공(1)(1')은 양쪽으로 나란히 미세한 길이로서 천공 절개되어 형성되고 그 사이에 가압력에 의해 함몰되어 이루어진 사다리꼴 형상의 돌출편(2)(2')이 형성되어 한개의 돌출편(2)(2')에 양쪽으로 관통된 2개의 흡음공(1)(1')이 형성된다. 1 is a partially enlarged perspective view of an embodiment according to the present invention, the sound-absorbing hole (1) (1 ') formed in the perforated plate 100 of the present invention is formed by cutting the perforations as a fine length side by side on both sides and the pressing force therebetween The trapezoidal protrusions 2 and 2 'formed by being recessed are formed to form two sound absorbing holes 1 and 1' penetrating to both sides of one protrusion 2 and 2 '. .

흡음공(1)(1')의 크기는 0.2∼2㎜의 범위에 속하고 용도에 따라 흡음공(1)(1')의 크기는 조절된다. The size of the sound absorption hole (1) 1 'falls in the range of 0.2-2 mm, and the size of the sound absorption hole (1) 1' is adjusted according to a use.

상기 2개 1조의 흡음공(1)(1')이 형성된 돌출편(2)(2')은 알루미늄이나 스틸, 스테인레스, 티타늄, 동, 등으로 이루어진 금속판재에 도 1에 도시된 바와 같이 일정한 방향으로 간격을 두고 격자상으로 연속 배열 형성된다. As shown in FIG. 1, the protrusion pieces 2 and 2 ′ in which the two sets of sound absorbing holes 1 and 1 ′ are formed are formed on a metal sheet made of aluminum, steel, stainless steel, titanium, copper, or the like. In a lattice form at intervals in the direction.

상기 돌출편(2)(2')은 금속판재를 천공하는 펀치의 금형에 의해 다양한 형상과 모양으로 형성될 수 있는 데 돌출편(2)(2')은 금속판재의 표면보다 돌출되어 접촉면적을 증가시키게 되어 소리의 많은 접촉으로 흡음효과를 높이게 된다. The protruding pieces 2 and 2 'may be formed in various shapes and shapes by a die of a punch for punching the metal sheet material. The protruding pieces 2 and 2' protrude more than the surface of the metal sheet material and thus have a contact area. This increases the sound absorption effect due to a lot of contact of sound.

도 5 내지 도 6은 돌출편(2)(2')의 높이가 측면에서 볼 때 경사지면서 다르게 형성되어 한쪽의 흡음공(1)(1')은 다른 쪽의 흡음공(1)(1')에 비해 작게 형성된 구조가 도시되고 있다.5 to 6 are differently formed while the height of the protruding pieces 2, 2 'is inclined when viewed from the side, so that one sound absorbing hole 1, 1' is the other sound absorbing hole 1, 1 '. The structure formed small compared to) is shown.

도 7 내지 도 8은 돌출편(2)(2')이 상면이 호형의 곡면으로 이루어지고 평면에서 보면 부채꼴 형상을 이루어 한쪽의 흡음공(1)(1')은 다른 쪽의 흡음공(1)(1')에 비해 적게 형성된 구조가 도시되어 있다. 7 to 8 show that the protruding pieces 2, 2 'have an arc-shaped curved surface, and in the plan view, they have a fan shape, and one sound absorbing hole 1, 1' has a sound absorbing hole 1 of the other. Less formed structure is shown as compared to 1).

도 9는 돌출편(2)(2')이 삼각형상으로 이루어진 구조로서 이 구조에서는 흡음공(1)(1')이 한개 형성되어 이루어진다. 9 is a structure in which the protrusion pieces 2 and 2 'are triangular-shaped, and in this structure, one sound absorption hole 1 and 1' is formed.

도 13 내지 도 15는 본 발명의 또 다른 실시예시도로서 돌출편(2)(2')이 앞의 구조와는 달리 한쪽 방향으로 형성되지 않고 돌출편(2)(2')이 지그재그로 형성된 구조를 나타내고 있다.13 to 15 are views showing another embodiment of the present invention, in which the protruding pieces 2, 2 'are not formed in one direction unlike the previous structure, and the protruding pieces 2, 2' are formed in a zigzag pattern. The structure is shown.

이 구조는 돌출편(2)(2')이 지그재그로 연속 설치되어 있으므로 타공판(100)을 상하 좌우 연접하여 설치할 때 돌출편(2)(2')의 방향에 관계없이 설치할 수 있는 잇점이 있다.This structure has the advantage that the projection pieces 2, 2 'are continuously installed in a zigzag and can be installed regardless of the direction of the projection pieces 2, 2' when the perforated plate 100 is connected vertically and horizontally. .

이와같이 된 본 발명은 금속판재에 구멍을 천공함에 있어 종래와 같이 단순히 구멍만을 천공하는 것이 아니라 천공과정에서 발생되는 판재의 돌출부를 일정한 형상이 되게 성형하면서 흡음공(1)(1')을 형성하여 표면적을 증가시키므로서 소리와의 접촉력을 높여 흡음효율을 높이는 특징이 있는 것으로, 알루미늄이나 스틸, 스테인레스, 티타늄, 동, 등으로 된 금속판재의 표면에 펀치와 금형을 이용하여 흡음공(1)(1')을 천공하면 흡음공(1)(1')이 도시된 바와 같이 다양한 형상으로 천공되면서 금형에 의해 돌출편(2)(2')이 형성된다. In the present invention as described above in forming a hole in the metal plate, instead of merely drilling a hole as in the prior art by forming the sound-absorbing hole (1) (1 ') while forming the protrusion of the plate generated in the drilling process to a certain shape It is characterized by increasing the surface area and improving the sound absorption efficiency by increasing the contact force with sound.The sound-absorbing hole (1) is made by using a punch and a mold on the surface of the metal plate made of aluminum, steel, stainless steel, titanium, copper, or the like. When the 1 ') is punctured, the sound absorbing holes 1 and 1' are drilled into various shapes as shown in the drawing to form the protruding pieces 2 and 2 'by the mold.

이때 돌출편(2)(2')은 판재의 표면보다 돌출되고 이의 양측에 흡음공(1)(1')이 형성되면서 한단위의 흡음공 어셈블리가 만들어지고 이러한 흡음공 어셈블리는 일정한 크기의 금속판재에 동시에 성형된다.At this time, the protruding pieces 2 and 2 'protrude from the surface of the plate and the sound absorbing holes 1 and 1' are formed on both sides thereof, thereby forming a unit of the sound absorbing hole assembly. It is molded at the same time on the plate.

도 1에 도시한 실시예는 기본적인 형태로서 돌출편(2)(2')이 사다리꼴로 이루어지고 이의 양측부에 흡음공(1)(1')이 천공되어 이들은 서로 관통되는 구조가 되는 데 상기 돌출편(2)(2')은 일정한 방향으로 형성되고 사이 사이에 돌출편(2)(2')이 형성된 격자상 형태로서 돌출편(2)(2')이 사다리꼴로 이루어져 절곡된 면이 증가하므로 타공판(100)의 표면적이 넓어져 타공판(100)에 접촉하는 소리의 음파가 보다 많은 접촉이 이루어지고 또 많은 수의 흡음공(1)(1')을 통해 유입되어 많은 공기층을 지나가면서 소리가 산란되므로 흡음효과가 상승하게 되는 것이다. The embodiment shown in Figure 1 is a basic form of the protrusion pieces (2) (2 ') made of a trapezoidal sound absorbing hole (1) (1') on both sides thereof are perforated to each other structure The protruding pieces 2 and 2 'are formed in a constant direction and have a lattice shape in which the protruding pieces 2 and 2' are formed therebetween. As the surface area of the perforated plate 100 increases, so that the sound waves of the sound coming into contact with the perforated plate 100 are made in contact with each other and are introduced through a large number of sound absorbing holes (1) (1 '), passing through a large number of air layers. Since sound is scattered, the sound absorption effect is increased.

즉, 흡음판의 흡음율은 타공의 수와 크기, 표면적에 의해 결정되므로 본 발명은 돌출편(2)(2')에 의한 접촉면적의 증가와 더불어 흡음공(1)(1')의 형태가 특이하여 한개의 돌출편(2)(2')을 통과한 소리가 인접하는 또 다른 흡음공(1)(1')을 통과하는 연속적인 과정이 반복하게 되므로 흡음효과는 매우 상승하게 된다.That is, since the sound absorption rate of the sound absorbing plate is determined by the number, size, and surface area of the perforations, the present invention is unique in the shape of the sound absorbing holes 1, 1 'with the increase of the contact area by the protruding pieces 2, 2'. Therefore, the sound passing through one protruding piece (2) (2 ') passes through another adjacent sound absorbing hole (1) (1') is repeated, so the sound absorption effect is very high.

도 5는 도 1의 돌출편(2)(2')의 변형된 구조로서 돌출편(2)(2')이 사다리꼴로 이루어지되 한쪽을 경사지게 형성하여 높이를 다르게 구성함으로써 흡음공(1)(1')의 한쪽은 다른 쪽보다 낮게 형성되어 있으므로 소리가 보다 많이 오래 접촉하여 소리의 산란현상을 높이게 됨에 따라 흡음효과는 더 높아지는 장점이 있다. 5 is a deformed structure of the protruding pieces 2 and 2 'of FIG. 1, and the protruding pieces 2 and 2' are formed in a trapezoidal shape, but the one side is formed to be inclined to form different heights to absorb sound holes 1 ( 1 ') is formed lower than the other side, so the sound is in contact with a lot longer to increase the scattering phenomenon of the sound has the advantage that the sound absorption effect is higher.

도 7은 돌출편(2)(2')의 상면을 곡면의 호상으로 형성하고 평면에서 볼 때 부채꼴이 되게 형성한 것이므로 흡음공(1)(1')의 크기가 달라 도 5와 같은 효과를 얻을 수 있으며 이 구조는 외관상으로 돌출편(2)(2')의 모양에 따라 부드러운 느낌을 주는 효과가 있다. 7 is formed by forming the upper surface of the protrusions (2) (2 ') in the shape of a curved arc and in a fan shape when viewed in a plane, the size of the sound absorbing holes (1) (1') is different, the same effect as in FIG. This structure has the effect of giving a soft feeling depending on the shape of the protrusions (2) (2 ') in appearance.

도 9에 도시한 돌출편(2)(2')은 금속판재의 표면보다 일측이 일정한 높이로 돌출된 삼각형태로서 돌출된 부위에 흡음공(1)(1')이 뚫려 흡음공(1)(1')으로 유입된 소리는 삼각형태의 표면과 마찰되어 흡음이 이루어지게 된다.9 is a triangular shape in which one side protrudes at a constant height from the surface of the metal plate, and the sound absorbing holes 1 and 1 'are formed in the protruding portions. The sound introduced into the 1 'is rubbed with the triangular surface to absorb sound.

도 13은 본 발명의 돌출편(2)(2')이 한쪽 방향으로 형성되지 않고 지그재그로 형성된 구조로서 돌출편(2)(2')이 교차되게 형성되어 있으므로 돌출편(2)(2')이 전기한 구조와는 달리 한쪽 방향으로 형성되지 않아 타공판(100)을 시공시 상하좌우 어느 방향으로도 연접시킬 수 있는 장점이 있어 시공상 편리하다. Fig. 13 is a structure in which the protruding pieces 2, 2 'of the present invention are formed in a zigzag structure without being formed in one direction, so that the protruding pieces 2, 2' are formed so as to intersect. Unlike the above-described structure, since it is not formed in one direction, there is an advantage in that the perforated plate 100 can be connected in any of up, down, left, and right directions in construction.

이와같은 본 발명의 미세 타공판(100)은 흡음공(1)(1')을 형성함에 있어 종래와 같이 천공시 발생하는 돌출부를 제거하지 않고 금형에 의해 일정한 형태로 형성한 것이므로 타공판(100)의 표면적이 증가하여 소리의 흡음율이 매우 높아지는 장점이 있고 돌출편(2)(2')의 형태에 따라 다양한 문양의 타공판(100)을 형성할 수 있으므로 건축자재로 사용시 실내외의 외관을 미려하게 장식할 수 있는 효과가 있다.Such fine perforated plate 100 of the present invention is formed in a predetermined shape by a mold without removing the protrusions generated during drilling in forming the sound absorbing hole (1) (1 ') of the perforated plate 100 As the surface area is increased, the sound absorption rate is very high, and the perforated plate 100 having various patterns can be formed according to the shape of the protruding pieces 2, 2 'so that the exterior of the room can be beautifully decorated when used as a building material. It can be effective.
