Description
본 발명은 천연목재의 목질 경도 및 강도를 단단하게 후가공 처리하기 위하여 사용하는 압축성형틀의 신규한 구성에 관한 것이다.The present invention relates to a novel construction of a compression mold used to harden the wood hardness and strength of natural wood.
벌채된 천연 목재를 가구류나 건축용 자재 등으로 실용화 하기 위하여서는 제재직전에 충분히 건조되어야 하므로 장시간의 건조 시간이 필요하다.In order to put the felled natural wood into furniture and building materials, it needs to be dried just before the sawing, so it takes a long time to dry.
또한 건조가 완료된 목재라 하더라도 이의 목재 섬유조직은 수분이 방출된 후 미세기공이 그대로 잔유되어 목질 밀도가 낮아지게 되므로 목재로서 요구되는 경도와 휨강도를 충족할 수 없게 된다.In addition, even if the wood is dried, its wood fiber tissue is not able to meet the hardness and bending strength required as wood because the micropore remains as it is, after the moisture is released, the wood density is low.
이러한 필요성에 따라 천연 목재를 소직경의 압축다이스 및 성형틀 속에 강제적으로 밀어 넣어 목재의 섬유조직속에 함침된 수분을 강제로 취출시키고 미세 기공을 압축하여 목질조직의 밀도를 높이므로서 목재의 재료 특성인 경도와 강도를 강화시키는 압축 가공법이 개발되기에 이른 것이다.According to this necessity, natural wood is forcibly pushed into compact dies and molds to force out the water impregnated into the fiber tissue and compress the micropores to increase the density of the wood tissue, thereby improving the material properties of the wood. Compression processing methods for enhancing phosphor hardness and strength have been developed.
이러한 필요성에 따라 본 발명자는 강제 압축방법에 의한 목재가공기를 개발하여 동일자로 출원한바 있으며 본 발명은 본 압축 성형기의 압축 성형틀의 구성을 보다 합리적으로 제공코져 함에 목적이 있다.In accordance with such a necessity, the present inventor has developed a wood processing machine by a forced compression method and has applied for the same. The present invention has an object to provide a rational configuration of a compression molding frame of the present compression molding machine.
천연 목재의 목질의 경도와 강도를 단단하게 하기 위한 압축 가공방법은 목재를 압축 성형다이스가 설치된 성형틀 속에 길이 방향으로 배치하고 유압피스톤을 이용하여 강한 정압력으로 압축 시킴과 동시에 목재에 음향진동과 좌우 교번운동(交番運動: TWISTING)을 부여하여 압축 효율을 증대시키는 방식을 취하게 된다.The compression processing method for hardening the hardness and strength of the wood of natural wood is arranged in the longitudinal direction in the molding frame with the compression molding dies and compressed with a strong static pressure using a hydraulic piston. The left and right alternating movement (TWISTING) is given to increase the compression efficiency.
이와 같은 압축 가공을 위한 성형틀은 높은 내압력에도 쉽게 견디고 초음파기로부터 음향 진동의 전달이 균형있게 전달되며 교번회전 운동에 의해서 목재와 성형틀의 마찰 운동시 내마모성이 양호하여야 하는 것이다.Such a molding mold for compression processing easily withstands high internal pressure, and the transmission of acoustic vibrations from the ultrasonic wave is balanced, and the wear resistance should be good during the frictional movement of the wood and the molding mold by alternating rotational movement.
따라서 압축 성형다이스 및 압축성형틀의 소재는 목재와 동일한 이방성 탄성을 갖는 특수한 소재여야 하며, 만일 이를 합금 및 금속제로 제작하여 성형다이스와 압축 성형틀을 구성하면 음향 파장에너지가 성형다이스 및 압축성형틀에서 감소 또는 소멸되어 목재에 도달하므로 효율적인 압축성형의 목적을 실현할 수 없게 된다.Therefore, the material of compression molding die and compression mold should be special material having the same anisotropic elasticity as wood, and if it is made of alloy and metal to form molding die and compression mold, acoustic wavelength energy is reduced in molding die and compression mold. Or it is extinguished and reaches the wood, so the purpose of efficient compression molding cannot be realized.
본 발명은 성형 다이스 및 압축성형틀의 재료를 목재에 음향파장 에너지가 최대한 효과적으로 전달될 수 있는 재질 특성으로 구성하려는데 그 과제를 두고 있다.An object of the present invention is to configure a material of a molding die and a compression molding mold with material properties that can effectively transmit acoustic wavelength energy to wood.

도1은 본 발명의 압축성형틀 및 압축성형다이스의 단면 구성을 나타낸다.1 shows a cross-sectional configuration of a compression mold and a compression die of the present invention.
압축성형틀(1)은 내통(3)과 외통(2)의 결합으로 이루어지고 이 전반부는 성형 다이스부(a)로서 이의 형태는 나팔형으로 입구부가 넓고 내측이 좁다.The compression mold (1) is made of a combination of the inner cylinder (3) and the outer cylinder (2), the first half is a forming die portion (a), the shape of which is trumpet-shaped, the inlet part is wide and the inner side is narrow.
후반부는 상기 다이스부(a)에 연결되는 원통형으로 구성되어 압축성형틀(1)의 몸체부(b)가 된다.The latter half portion is formed in a cylindrical shape connected to the die portion (a) to be the body portion (b) of the compression mold (1).
다이스부(a)는 목재가 강제 진입되는 부분이고 몸체부(b)는 목재가 압축력을 받아 응축가공되는 성형부로 된다.The die portion (a) is a portion into which the wood is forced to enter and the body portion (b) is a molding portion in which the wood is condensed under compression.
몸체부(b)는 다수의 통공(4)이 천설되어 목재가 압축 가공될시 나무즙(목즙)이 밖으로 취출되는 배수공의 역할을 한다.The body portion (b) serves as a drain hole in which a plurality of through-holes 4 are laid and the tree juice (tree juice) is taken out when the wood is compressed.
다이스부(a)와 몸체부(b)는 이중통으로 이루어지며 내통(3)은 그라스화이바가 내입된 에폭시수지 등 강화 프라스틱재로 형성하고 외통(2)은 단단하고 수분이 적은 목재로서 성형하되 목재밀도는 보통 목재보다 1.3배이상, 습기는 8%이하의 것으로 선택한다.The die part (a) and the body part (b) are made of double cylinders, and the inner cylinder (3) is formed of reinforced plastic material such as epoxy resin into which glass fibers are embedded, and the outer cylinder (2) is molded as hard and low moisture wood. Density is usually chosen to be 1.3 times higher than wood and 8% or less.
그리고 목재섬유 방향은 압축성형기의 축심(0-0')과 동일 방향으로 구성하며 이의 음향진동 전달 속도는 1초에 3000m 이상의 고밀도로 되는 단단한 재료를 선택한다.The direction of the wood fiber is made in the same direction as the axis (0-0 ') of the compression molding machine, and its acoustic vibration transmission speed is selected to be a rigid material with a high density of 3000m or more per second.
상기 구성에 있어서 압축성형기용 재료인 목재의 섬유 방향이 압축성형기축0-0'방향과 일치되도록 하는 것은 압축 성형기의 종단, 횡단의 음향 저항과 압축하려는 목재의 종단, 횡단 음향 저항을 일치시키기 위한 것이다.In this configuration, the fiber direction of the wood, which is the material for the compression molding machine, coincides with the direction of the compression molding machine axis '0', so as to match the end of the compression molding machine, the transverse acoustic resistance with the end of the wood to be compressed, and the transverse acoustic resistance. will be.
압축성형기와 압축하려는 목재의 음향 특징이 일치되면 성형기 경계면에서 손실되는 음향 에너지가 적어지고 음향파장이 가공목재 내부로 깊숙이 효과적으로 전달되어 가공 목재의 에너지 밀도가 높아지고 전체 면적에 균등하게 음향 전달이 가능하여진다.If the acoustic characteristics of the compression molding machine and the wood to be compressed are matched, the acoustic energy lost at the interface of the molding machine is reduced, and the acoustic wavelength is effectively transmitted deeply into the processed wood, which increases the energy density of the processed wood and allows the sound to be transmitted evenly over the entire area. Lose.
또한 압축 성형기를 건조되고 단단하게 압축시킨 나무로 만드는 것은 생나무로 만드는 것에 비해 변형을 없애기 위함이며 또한 고압력과 고온에서도 변화하지 않도록 하기 위함에 목적이 있다.In addition, the compression molding machine made of dried and hard compressed wood is intended to eliminate deformation as compared to made of raw wood, and also to prevent it from changing under high pressure and high temperature.
또한 음향 진동의 전달 속도가 1초에 3000m이하이면 목재 구조에 금, 균열 등 밀도의 취약성이 있음을 의미하며 이러한 재료 특성은 가공 목재와 그 압축성형기 간에 음향전달을 나쁘게 한다.In addition, if the transmission speed of the acoustic vibration is less than 3000m per second, it means that there is a weakness of density, such as cracks and cracks, in the wood structure, and this material property worsens the sound transmission between the processed wood and the compression molding machine.
본 발명의 구성에 있어서 성형틀의 내측에 유리섬유 강화 프라스틱 보강재(에폭시수지등)를 이중으로 접착하는 것은 목재의 압축 성형중 마찰 저항에 잘 견디게 하고 마모도를 감소시키기 위한 보강 기능을 부여하기 위한 것이다.In the configuration of the present invention, double-bonding the glass fiber reinforced plastic reinforcement material (epoxy resin, etc.) to the inside of the molding die is to give a reinforcing function to withstand the frictional resistance during compression molding of wood and to reduce wear. .
성형틀 본체의 통공(4)은 목재의 압축 가공 과정에서 목재의 섬유조직 속에서 강제로 취출된 수분 즉 목즙을 밖으로 자연스럽게 배출시키는 착즙공의 역할을 하고 또한 성형틀 전체의 내압 강도를 높이는 역할을 한다.The through hole 4 of the main body of the mold serves as a juicer for naturally draining the water, that is, the juice, which is forcibly taken out of the wood fiber during the compression processing of the wood, and also serves to increase the pressure resistance of the entire mold. do.
본 발명은 이상과 같이 목재의 재질 특성을 보다 단단하고 견고하게 유지시키기 위한 음향전달 방식에 의한 압축가공 성형을 위한 성형틀의 구성에 있어서, 이의 형태를 성형 다이스부(a)와 성형틀 몸체 부분을 단일체로 연결 형성하고 이의 재료를 단단하고 수분이 적은 목재 즉, 목재밀도 1.3배 이상, 함수율 8%이하인 고밀도의 나무통으로 구성하고 이의 내부에 유리섬유 강화 프라스틱수지재 등의 보강관체가 내장 결합되는 이중 구조를 형성하므로서 목재의 압축가공 공정에 있어서 목재에 대해 음향 전달을 보다 용이하게 하고 고압력을 쉽게 전달할 수 있게 하여 목재 재료의 고밀도 가공을 보다 효율화 할 수가 있는 것이다.The present invention in the configuration of the molding die for compression processing molding by the acoustic transmission method for maintaining the material properties of the wood more firmly and firmly as described above, the shape of the forming die portion (a) and the mold body portion Is formed into a single body, and its material is composed of hard and low-moist wood, that is, a high-density wooden barrel with a wood density of 1.3 times or more and a water content of 8% or less. By forming a double structure in the compression processing process of wood, it is possible to more easily transmit the sound to the wood and to transmit the high pressure to make the high-density processing of the wood material more efficient.
