합성수지재 절단용 커터 나이프의 커터날 접합방법{Cutting edge adhesion method of synthetic resin cut off cutter knife}Cutting edge adhesion method of synthetic resin cut off cutter knife}

본 발명은 합성수지재 절단용 커터 나이프의 커터날 접합방법에 관한 것으로, 더욱 상세하게는 강도가 높은 커터날과 커터본체을 상이한 재질의 금속을 박판형 금속접합재를 사용하여 커터날의 손상이 작게 하는 커터날 접합방법에 관한것이다.The present invention relates to a cutter blade joining method of a cutter knife for cutting a synthetic resin material, and more specifically, a cutter blade for reducing the damage of the cutter blade by using a thin metal bonding material of a metal of different materials for the cutter blade of high strength and the cutter body. It is about joining method.

보편적으로 석유화학 분야에서는 가공재료의 용도로 합성수지재를 생산함에 있어서 포장 및 가공재료로 편리하게 이용하기 위해 커터 나이프를 사용하여 소정크기로 칩(Chip)형태로 절단하고 있다.In general, in the petrochemical field, a cutter knife is used to cut a chip to a predetermined size in order to conveniently use it as a packaging and processing material in producing synthetic resin materials for processing materials.

이러한, 합성수지재는 커터나이프로 용이하게 절단하기위하여 고온의 스팀으로 합성수지재를 반죽상태로 다이플레이트의 다수개의 관들을 통하여 봉형상으로 압출되어 나오면 봉형상으로 압출된 상태의 합성수지재를 다수개가 커터나이프가 설치된 로터리 회전판를 이용하여 소정길이의 칩형태로 절단되도록 이루어진다.Such a synthetic resin material is extruded into a rod shape through a plurality of pipes of the die plate in the state of kneading the synthetic resin material with high temperature steam in order to easily cut the cutter knife, and a plurality of the cutter knives are extruded in the rod shape. It is made to be cut into chips of a predetermined length using a rotary rotary plate installed.

위와 같은 종래에 사용되는 커터나이프는 고속의 정밀절삭공구에 사용되는 TiC (Titanium Carbide, 이하 TiC)계를 주 재질로 이용하여 일체로 형성된 커터나이프를 제작하였다.The cutter knife used in the related art as described above manufactured a cutter knife formed integrally using TiC (Titanium Carbide (TiC)), which is used as a high-speed precision cutting tool, as a main material.

이러한 TiC계 재질이 일체로 형성된 커터나이프는 고경도의 단일재질로 이루어져 인장강도가 낮고 경도가 높은 고경도 금속재질임으로, 합성수지재의 고속절단 작업 시 커터나이프의 커터날 부분에 전달되는 연속적인 충격을 흡수나 분산을 시키지 못하여 커터날이 부러지게되거나 균열이 생기는 문제점이 있었다.The cutter knife formed of such TiC-based materials is made of a single material of high hardness and is a high hardness metal material with low tensile strength and high hardness. Therefore, the cutter knife has a continuous impact transmitted to the cutter blade part of the cutter knife during the high speed cutting operation of the synthetic resin material. There was a problem that the cutter blade is broken or cracked due to absorption or dispersion.

또한, 합성수지재 절단작업시 다이플레이트에서 압출되어 나오는 반죽형태의 합성수지재에서 발생되는 고온과 수분을 함유한 스팀이 발생함으로서 습기에 의한 내식성이 낮은 TiC계재질의 커터나이프가 쉽게 부식되는 문제점 있었다.In addition, since the high temperature and moisture-containing steam generated from the dough-type synthetic resin material extruded from the die plate during the cutting operation of the synthetic resin material, the cutter knife of the TiC-based material having low corrosion resistance due to moisture was easily corroded.

이런 문제점들로 인하여 커터나이프의 수명이 단축되는 문제점 있을 뿐만아니라 , 커터나이프에 사용되는 TiC계재질은 고가의 재질이기 때문에 생산에 소요되는 비용이 증가되는 문제점이 있었다.Due to these problems, not only the life of the cutter knife is shortened, but also the TiC-based material used for the cutter knife has a problem of increasing the cost required for production.

따라서, 본 발명은 상기와 같은 제반 문제점을 해소하기 위하여 안출한 것으로서, 본 발명의 목적은 합성수지의 절단작업 시 다이플레이트에서 압출되어 나오는 합성수지 반죽물을 절단하는 커터나이프의 커터날부와 커터나이프 본체를 이형재질로 구성하여 박판형 금속접합재를 이용하여 용융접합시켜 일체로 형성함으로서, 충격 방지 및 충격 분산을 쉽게하고 커터날 부분의 부식을 방지할 수 있는 커터나이프의 접합방법을 제공하는데 있다.Therefore, the present invention has been made to solve the above problems, the object of the present invention is to cut the cutter blade and the cutter knife body of the cutter knife for cutting the synthetic resin dough extruded from the die plate during the cutting operation of the synthetic resin The present invention provides a method of joining cutter knives that can be formed of a release material and melt-bonded using a thin metal bonding material to form a single body, thereby easily preventing impact and dispersing impact and preventing corrosion of the cutter blade portion.

이와 같이 본 발명은 일측에 다수개의 채결공이 관통형성되고 타측에 커터날 결합부를 갖는 커터날 본체와 충격 방지 및 충격 분산률이 높고 산화성이 낮은 Tic재질의 금속을 사용한 커터날을 Ag 60~72중량부, Cu 15~20중량부 및 Zn 13~20중량부로 이루어진 박판형 금속접합재를 750~900℃ 용융온도로 용융접합시켜 절단 효과가 우수한 커터 나이프를 구성하는 것이다.As described above, the present invention provides a cutter blade body having a plurality of chamfering holes formed on one side and a cutter blade coupling portion on the other side, and a cutter blade using a metal of Tic material having high impact resistance and low impact dispersion rate and low oxidizing property. A thin plate metal bonding material composed of 15 to 20 parts by weight of Cu and 13 to 20 parts by weight of Zn is melt-bonded at a melting temperature of 750 to 900 ° C. to form a cutter knife having an excellent cutting effect.

이하 본 발명의 바람직한 실시 예에 따른 커터 나이프 접합방법을 첨부도면을 참조하여 상세히 설명한다Hereinafter, a method of joining a cutter knife according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명에 따른 커터 나이프를 도시한 부분 분해 사시도이고, 도 2는 본 발명에 따른 커터 나이프를 도시한 사시도이고, 도 3은 본 발명에 따른 커터 나이프를 도시한 단면도이다.1 is a partially exploded perspective view showing a cutter knife according to the present invention, Figure 2 is a perspective view showing a cutter knife according to the present invention, Figure 3 is a cross-sectional view showing a cutter knife according to the present invention.

도면에 도시된 바와 같이, 석유화학 분야에서 합성수지재를 생산하는 다이플레이트 일측에 다이플레이트에서 압출되는 합성수지재를 칩형태로 절단하기 위해 다이플레이트에 다수개의 커터 나이프가 설치된 고소회전하는 회전판을 설치함으로서 다이플레이트의 합성수지재 압출부에 커터나이프가 일접하게 접속되어 회전하게 됨으로 인하여 수기재가 커터 나이프의 커터날(2)에 의해 절단되는 것이다.As shown in the figure, by installing a high-speed rotating plate provided with a plurality of cutter knives on the die plate to cut the synthetic resin material extruded from the die plate on one side of the die plate for producing a synthetic resin material in the petrochemical field The cutter material is cut by the cutter blade 2 of the cutter knife because the cutter knife is connected to and rotated in direct contact with the synthetic resin extrusion part of the die plate.

이때, 커터 나이프의 커터날(2)을 형성하기위해 충격에 강하며 부식이 되지 않는 재질의 금속인 Tic재질의 금속을 사용하는 것이 바람직함으로 커터날(2)과 커터날 본체(1)를 이형제질로 구성하는 것이 바람직 할 것이다.At this time, in order to form the cutter blade (2) of the cutter knife, it is preferable to use a metal of Tic material, which is a metal of a material which is resistant to impact and does not corrode, thereby releasing the cutter blade (2) and the cutter blade body (1) It would be desirable to make it into a material.

이러한, 커터 나이프를 접합하기 위한 접착재를 박판형의 금속접학재(3)를 이용하여 접합하는 것이 바람직 할 것이며 금속접합재(3)의 성분 비는 Ag 60~72중량부, Cu 15~20중량부, Zn 13~20중량부로 이루어진 합금재질이 바람직하며 또한 그 성분 비를 Ag 50~54중량부, Cu 15~22중량부, Zn 12~19중량부, Cd 15~22중량부, Ni 1~3중량부로 할 수도 있다.It is preferable to bond the adhesive material for joining the cutter knife using a thin metal adhesive material 3, and the component ratio of the metal adhesive material 3 is 60 to 72 parts by weight of Ag, 15 to 20 parts by weight of Cu, Alloy material consisting of 13 to 20 parts by weight of Zn is preferable, and the component ratio is 50 to 54 parts by weight of Ag, 15 to 22 parts by weight of Cu, 12 to 19 parts by weight of Zn, 15 to 22 parts by weight of Cd, and 1 to 3 parts by weight of Ni. You can also do it.

상기 각성분조성비를 벗어나면 커터날 본체와 커터날과의 접합시 접합력이 저하되는 문제점 있다.Deviation from the angular component composition ratio has a problem that the bonding force is lowered when the cutter blade main body and the cutter blade is bonded.

또한, 커터날 본체와 커터날과의 접합시 금속접합재의 용융 온도를 750~900℃를 가열함으로서 이루어진다. 이 온도하에서 접합이 잘 이루어지며 상기 온도를 벗어나면 장기간 사용시 접합력이 저하되는 문제점이 발생할 수 있다.In addition, the melting temperature of the metal bonding material during the joining of the cutter blade main body and the cutter blade is achieved by heating 750 to 900 ° C. Bonding is performed well under this temperature, and if the temperature is out of the above range, the bonding strength may deteriorate when used for a long time.

도 3에 도시된 바와 같이 커타 나이프는 커터날 몸체(1)에 형성된 커터날 결합부(11) 에 커터날(2)을 용융접합하기 위해 박판형 금속접합재(3)를 커터날 몸체(1)와 커터날(2) 사이에 게재한 후 박판형 금속접합재(3)를 가열하고 일정한 압력을 가함으로서 정밀한 커터 나이프가 생상되는 것이다.As shown in FIG. 3, the cutter knife includes a sheet metal bonding material 3 and a cutter blade body 1 to melt-bond the cutter blade 2 to the cutter blade coupling portion 11 formed on the cutter blade body 1. After placing between the cutter blades 2, a fine cutter knife is produced by heating the thin metal bonding material 3 and applying a constant pressure.

이러한 접합방법은 커터날 본체(1)와 커터날(2)은 용융되지 않고 단지 금속접합재(3)가 용융되어 접합되는 것으로 일종에 브레이징 원리를 이용함으로서 보다 정말한 커터 나이프를 생산할 수 잇는 것이며, 이렇게 접합된 커터 나이프는 커터날(2)의 수명이 다 되었을때 커터날(2) 부위만 분리 폐기하고 커터날 본체(1)는 다시 재활용 할 수 있는 장점을 지닐 수 있게 하였다.This joining method is that the cutter blade main body 1 and the cutter blade 2 are not melted, but only the metal bonding material 3 is melted and joined. When the cutter knife is bonded so that the life of the cutter blade (2) is finished, only the cutter blade (2) parts are separated and discarded, and the cutter blade body (1) has the advantage that can be recycled again.

지금까지 본 발명에 따른 바람직한 실시예를 들어 도시하고 설명하였으나, 본 발명은 상기한 실시예에 한정되지 아니하며, 본 발명의 정신을 벗어나지 않는 범위 내에서 본 발명이 속하는 기술 분야에서 통상의 지식을 갖은 자에 의해 다양한변경과 수정이 가능할 것이다.While the present invention has been illustrated and described with reference to preferred embodiments, the present invention is not limited to the above-described embodiments, and the present invention is not limited to the above-described embodiments, and has a general knowledge in the technical field to which the present invention belongs.
