본 발명은 하니컴구조체의 압출성형용 금형에 관한 것으로 더 상세하게는 관상공부위의 도입통로와 선단부위의 성형용 통로가 직접 상호 관통하도록 되어 있어 배토의 압출저항을 감소시켰고, 도입통로와 성형용 통로사이에 원추형태의 홈을 형성시켜 압력분배를 균등하게 하였으며, 또한 도입통로가 다수 설치된 관상공부위와 성형용통로가 다수 설치된 선단부위를 일체화시켜 가공 및 제작이 용이하도록 한 하니컴구조체의 압출성형용 금형에 관한 것이다.The present invention relates to an extrusion molding die of a honeycomb structure, and more particularly, the introduction passage of the tubular hollow portion and the forming passage of the tip portion pass directly through each other, thereby reducing the extrusion resistance of the clay, and the introduction passage and the molding die. Cone-shaped grooves are formed between the passages to equalize pressure distribution, and the extrusion molding of the honeycomb structure for easy processing and fabrication by integrating the tubular hole portion having a plurality of introduction passages and the tip portion having a plurality of forming passages. It is about a mold.
종래의 하니컴구조체의 압출성형용 금형은 제1도의 단면도에 나타낸바와같이 관상공부위와 선단부위 사이를 접착이나 확산소결 등의 접착방법을 이용하여 접착시켜 구성된다.The conventional die for extrusion molding of a honeycomb structure is constructed by adhering between a tubular hole and a tip portion using an adhesive method such as bonding or diffusion sintering as shown in the cross-sectional view of FIG.
접착되기 전 관상공부위에는 소정간격을 두고 배토가 압입되는 원형의 도입통로를 다수 설치하고, 또한 선단부위에도 하니컴 형상의 격자상을 갖도록 성형용 통로를 소요형상으로 설치한 후 이성형용통로와 도입통로가 소정위치에서 직접 상호 관통하는 구조가 되도록 접착되어진다.Before joining, install a large number of circular introduction passages through which clay is press-fitted at predetermined intervals in the coronal air space, and also install the forming passages in the required shape to have honeycomb-like lattice shape at the leading end, It is bonded so that the structure penetrates directly to each other at a predetermined position.
전술한 종래의 금형을 상세히 설명하면 제1도의 단면도와 제2도의 후면도에 나타낸 바와 같이 각각의 성형용 통로 도입측이 도입통로 배출측과 상호 관통하는 것이 아니고 성형용 통로가 하나걸러 하나씩 도입통로와 직접 상호 관통하도록 되어 있다.Referring to the above-described conventional mold in detail, as shown in the cross-sectional view of FIG. 1 and the back view of FIG. 2, each forming passage introduction side does not penetrate the introduction passage discharge side, but each forming passage is introduced one by one. It is intended to penetrate directly with each other.
이와같은 구조는 배토의 압출저항이 크고 압력분배가 균등치 않으며 일체화 되지 않아 가공 및 제작이 난이한 결점이 있는 것이다.Such a structure has a disadvantage in that the extrusion resistance of the clay is large, the pressure distribution is not uniform, and it is not integrated, so it is difficult to process and manufacture.
본 발명에 대한 종래 기술중 일본공개특허공보(소60-129253호)는 하니컴구조체 외벽의 두께를 조절할 수 있는 압출성형용 금형이다.Japanese Patent Laid-Open No. 60-129253 in the prior art for the present invention is an extrusion molding die that can adjust the thickness of the outer wall of the honeycomb structure.
이는 하니컴구조체의 외벽을 형성하기 위한 성형통로의 길이가 서로 다를뿐만 아니라 내벽형성용 성형통로의 길이가 외벽형성용 성형용통로의 길이보다 크다.Not only are the lengths of the forming passages for forming the outer wall of the honeycomb structure different from each other, but the length of the forming passage for forming the inner wall is larger than the length of the forming passage for forming the outer wall.
하니컴구조체의 외벽두께를 조절하기 위해 금형의 재료출구측 외벽형성부에 경사면 및 수직면이 설치되어 있다.In order to control the thickness of the outer wall of the honeycomb structure, the inclined surface and the vertical surface are provided on the outer wall forming portion of the material exit side of the mold.
또한 금형지지대(die mask)의 외벽형성부에 금형으로부터 출구측으로 향하는 테퍼를 형성시켰다.Further, a taper was formed in the outer wall forming portion of the die mask from the mold toward the outlet side.
그러나 본 발명은 하니컴 형상을 갖도록 하는 외벽형성용 내벽 형성용 성형용 통로의 길이가 모두 같다.However, in the present invention, the length of the forming passage for forming the inner wall for forming the outer wall to have a honeycomb shape is the same.
종래의 금형은 관상공부위와 선단부위를 접착 또는 확산소결 등에 의해 접착시켰고, 또한 성형용통로의 도입측이 도입통로의 배출측과 상호연결되는 구조가 아니라 성형용통로가 하나걸러 하나씩 도입통로와 연결된 구조로 되어 있다.In the conventional mold, the tubular hole and the tip are bonded to each other by bonding or diffusion sintering, and the molding passage is not connected to the discharge side of the introduction passage, but the molding passage is connected to the introduction passage one by one. It is structured.
본 발명에서는 도입통로와 성형용통로 일체화시켜 가공 및 제작이 용이하도록 하였고, 도입통로와 성형용 통로가 직접 연결되는 구조하여 압출저항을 감소시켰고, 도입통로 끝부분에 원추형상의 홈을 형성시켜 재료에 걸리는 압력분배를 균등하게 하였다.In the present invention, the introduction passage and the forming passage are integrated to facilitate processing and fabrication, and the introduction passage and the forming passage are directly connected to reduce extrusion resistance, and conical grooves are formed at the end of the introduction passage to form a material. The pressure distribution required is equalized.
결국, 종래 기술과 본 발명의 차이점은 금형과 금형 마스크를 조인트볼트에 의해 일체화 시킬 수 있는 점은 동일하나 금형의 발명취지가 다를뿐만 아니라 아래와 같은 세부사항이 다르다.As a result, the difference between the prior art and the present invention is that the mold and the mask of the mold may be integrated by the joint bolt, but the intention of the mold is different, as well as the following details.
본 발명은 하니컴구조체의 외벽과 내벽의 두께가 균일하도록 한 금형이고, 일본특허의 경우는 외벽의 두께를 조절할 수 있도록 한 금형이다.The present invention is a mold in which the thickness of the outer wall and the inner wall of the honeycomb structure is uniform, and in the case of the Japanese patent, the mold can adjust the thickness of the outer wall.
또 일본 특허의 경우는 본 발명과는 다르게 하니컴구조체의 외벽 두께조절을 위하여 금형의 외벽형성부에 경사면 및 수직면을 설치하였고 금형지지대(mask)에 테퍼를 형성시켰다.In addition, in the case of the Japanese patent, in order to control the thickness of the outer wall of the honeycomb structure, the inclined surface and the vertical surface were installed on the outer wall forming portion of the mold, and a taper was formed on the mold support (mask).
또 일본 특허의 경우는 외벽두께 조절을 위해 길이가 다른 여러개의 성형용통로가 있고 이 통로의 길이는 내벽형성용 성형용통로보다 짧으나, 본 발명은 외벽형성을 위해 1개의 성형용통로가 있고, 이 통로 길이는 내벽형성용 성형용통로와 같다.In addition, in the case of the Japanese patent, there are several molding passages having different lengths for adjusting the outer wall thickness, and the length of the passages is shorter than the forming passages for forming the inner wall, but the present invention has one forming passage for forming the outer wall, This passage length is the same as the forming passage for forming the inner wall.
그리고 일본공개특허공보(소61-5915호) 하니컴구조체 외벽의 두께가 내벽보다 두껍도록 한 압출성형용 금형이다.Japanese Laid-Open Patent Publication No. 61-5915 is an extrusion molding die in which the outer wall of the honeycomb structure is thicker than the inner wall.
이는 재료가 외벽형성용 성형용통로에 유입되기전 위치에 도입통로에 연결된 분지유로와 그 분재유로들을 합류시켜 내벽형성용 성형용통로의 폭보다 큰 외벽형성용 성형용통로를 형성시켜 출구측에서의 재료의 유속을 동일하도록 하였다(외벽형성용 성형용통로의 폭이 내벽형성용 성형용통로보다 큼).This causes the branch flow passage connected to the introduction passage and its bonsai flow passage to be joined at the position before the material flows into the forming passage for forming the outer wall to form the forming passage for forming the outer wall which is larger than the width of the forming passage for forming the inner wall. The flow velocity of was equal to (the width of the forming passage for forming the outer wall is greater than the forming passage for forming the inner wall).
즉, 재료가 압입되는 원형의 도입통로가 선단부위 절반지점까지 설치되어 있다.That is, a circular introduction passage through which the material is press-fitted is provided up to half of the tip portion.
결국 이 기술과의 차이점은 도입통로와 성형용통로가 상호관통된 구조이나 발명의 취지가 다를뿐만아니라 아래와 같은 세부사항이 다르다.After all, the difference from this technique is that the introduction passage and the forming passage are mutually penetrated and the intent of the invention is different as well as the following details.
본 발명은 선단부위에 위치한 외벽형성용 내벽형성용 성형용통로의 폭이 동일하고 외벽형성용 성형용통로와 연결된 분지유로가 설치되어 있지 않으나, 일본 특허의 경우는 외벽형성용 성형용통로의 폭이 내벽형성용 성형용통로 보다 크고, 재료유속을 조절하기 위한 분지유로가 설치되어 있다.In the present invention, the width of the forming wall for forming the inner wall formed at the distal end is the same and the branch passage connected to the forming wall for forming the outer wall is not provided. It is larger than the forming passage for forming the inner wall, and a branch passage for adjusting the material flow rate is provided.
또 본 발명은 도입통로가 선단부위와 접하고 있는 관상공 부위에만 위치하고 있으나 일본 특허의 경우는 선단부위 위치 절반지점까지 설치되어 있다.In the present invention, although the introduction passage is located only in the coronal air space where the tip portion is in contact with the tip portion, the Japanese patent is provided up to half of the position of the tip portion.
본 발명은 이와같은 상기의 모든 종래의 결점을 제거코져한 것으로서 그 요지를 제3도, 제4도의 실시예를 기준으로 상세히 설명하면 다음과 같다.The present invention removes all of the above-mentioned conventional drawbacks, and the gist thereof will be described in detail with reference to the embodiments of FIGS. 3 and 4 as follows.
배토가 압입되는 원형의 도입통로(3)가 다수 설치된 관상공부위(1)와 하니컴형상으로 성형하는 격자상의 성형용통로(5)가 다수 설치된 선단부위(2)가 일체화되어 있는 후면부금형(제3도)과 하니컴구조체의 외피를 형성하고 후면부금형에 걸리는 압력을 지지해 주는 전면부 금형을(제4도), 두 파트로 분리 구성되어 있어 후면 부금형을 밑에 두고, 전면부 금형을 후면부금형에 맞게 조립한 후 육각볼트를 사용, 접합시킬 수 있는 구조로 되어 있다.The rear part mold in which the tubular hollow part 1 having a large number of circular inlet passages 3 into which the soil is press-fitted is integrated with the tip part 2 having a plurality of lattice-shaped forming passages 5 formed in a honeycomb shape. 3)) and the front mold (4 degrees), which forms the outer shell of the honeycomb structure and supports the pressure applied to the rear mold, is divided into two parts. After assembling according to the structure, hex bolts can be used to join.
후면부 금형의 관상공부위에는 종래의금형과 같이 소정간격을 두고 원형의 도입통로를 다수 설치하고, 선단부위에는 도입통로의 배출측과 만나는 성형용통로의 도입측에는 성형용 통로의 약 1/4깊이에 원추형태의 홈(4)을 형성시켜 이 홈이 도입통로와 상호 관통되는 구조로 되어 있다.In the tubular hollow part of the rear mold, a large number of circular inlet passages are provided at a predetermined interval as in the case of the conventional mold, and at the tip end, a cone is formed at about 1/4 depth of the forming passage on the inlet side of the forming passage which meets the discharge side of the inlet passage. The groove 4 of the shape is formed so that the groove penetrates the introduction passage.
이 원추형태의 홈은 도입통로의 배출측의 폭과 같게 하고 성형용 통로의 유입측의 폭과 같게 형성시킴으로 해서 도입통로에서 성형용 통로로 유입되는 배토에 걸리는 압력분배를 균등하게 하였다.This conical groove was formed to have the same width as the discharge side of the introduction passage and the same width as the inflow side of the forming passage so that the pressure distribution applied to the topsoil flowing into the forming passage from the introduction passage was equalized.
선단부위의 배출측에는 하니컴형상을 갖도록 하는 격자상의 성형용통로를 도입통로의 폭보다 작게 소정폭으로 다수 형성시켜 도입통로와 직접 상호관통하도록 되어 있다.On the discharge side of the tip portion, a plurality of lattice-shaped molding passages having a honeycomb shape are formed in a predetermined width smaller than the width of the introduction passage so as to directly interpenetrate with the introduction passage.
전술한 실시예에 있어서 선단부위의 성형용통로는 하니컴형상을 갖도록 격자상으로 되어 있으므로 소정형상을 육각형, 팔각형, 원형 등의 형상으로 할 수 있다.In the above-described embodiment, the forming passage at the tip portion is in the form of a lattice to have a honeycomb shape, so that the predetermined shape can be a hexagon, an octagon, a circle, or the like.
이와같이된 본 발명의 금은 도입통로의 배출측이 성형용통로의 유입측과 직접 상호 관통하는 구조로 되어 있어 도입통로와 성형용통로와의 불일치에 의한 부분적인 배토 압출저항을 감소시켰다.Thus, the gold of the present invention has a structure in which the discharge side of the introduction passage penetrates directly with the inflow side of the forming passage, thereby reducing partial extrusion extrusion resistance due to the mismatch between the introduction passage and the forming passage.
또한 성형용 통로의 도입측에는 도입통로의 폭과 같고 성형용 통로의 폭과 같은 원추형태의 홈을 형성시킴으로 해서 성형용통로로 유입되는 배토에 걸리는 압력분배를 균등하게 하여 안정한 압출성형이 가능하게 하였다.In addition, by forming a conical groove equal to the width of the introduction passage and the width of the forming passage on the introduction side of the forming passage, the pressure distribution applied to the clay that flows into the forming passage is equalized, thereby enabling stable extrusion molding. .
이러한 이유로 압출압을 작게하는 것이 가능하므로 압출기의 부하도 작게 할 수 있다.For this reason, it is possible to reduce the extrusion pressure, so that the load on the extruder can be reduced.
본 발명의 재질은 강도 및 경도가 우수한 SKD-11 공구강을 사용하였고 이온질화 분위기하에서 열처리 하였으며 압출성형시 금형내부의 내마모성을 증진시키기 위해 내부를 Ni도금 처리하였다.The material of the present invention used SKD-11 tool steel with excellent strength and hardness, heat treated in an ionized atmosphere, and Ni-plated inside to improve wear resistance in the mold during extrusion.
