Abstract

PURPOSE: A method for manufacturing a PVC pulverizing cutter is provided to obtain an excellent durability and long life by using special steel and structural steel. CONSTITUTION: A PVC pulverizing cutter manufacturing method comprises the steps of: producing a cutter body(10) by using structural steel(SS41) as a base metal; cutting a part for combination of a blade part from the cutter body; adhering a blade part(20) made of special steel(SKS3) to a blade combining face after sprinkling iron powder to the blade combining face; heating the cutter body and the blade part in an electric furnace at 1100deg.C of temperature; combining the cutter body with the blade part by repeatedly hammering; milling the cutter body and the blade part to sharpen the blade end; thermally processing a milled PVC pulverizing cutter; and processing a hole. Therefore, a PVC pulverizing cutter having excellent wear resistance is obtained. Moreover, the blade is not easily separated from the cutter body.

Description

재활용 피브이씨 분쇄용 칼의 제조방법{A manufacturing method of nife for crush}A manufacturing method of nife for crush

본 발명은 재활용 PVC 분쇄용 칼의 제조방법에 관한 것이다.The present invention relates to a method for producing a recycled PVC grinding knife.

제품으로 성형되어 폐기된 PVC는 재활용하기 위해서 상기 재활용 PVC를 잘게분쇄하기 위한 장치가 필요하게 되고, 상기 장치에는 도 1에 도시한 바와같은 형태를 갖는 분쇄용 칼이 축에 다수개 장착되어 회전하면서 장치에 투입된 PVC를 잘게 잘라 분쇄하게 된다.The PVC molded and discarded as a product requires a device for finely pulverizing the recycled PVC in order to be recycled, and a plurality of grinding knifes having a shape as shown in FIG. The PVC put into the device is chopped and pulverized.

따라서 상기 분쇄용 칼은 대량의 PVC를 절단하거나 분쇄하여야 하므로 칼날부의 마모와 내구성이 가장 중요하며, 마모율을 좋게 하기 위하여 여러가지 특수강을 사용하기도 한다.Therefore, the grinding knife has to cut or pulverize a large amount of PVC, so the wear and durability of the blade portion is the most important, and various special steels may be used to improve the wear rate.

즉 구조강의 일종인 SS41를 재질로 하여 칼의 형태를 만들고, 상기 칼의 끝을 예리하게 절개해 내어 칼날을 형성하여 사용하기도 하나, 이는 구조강의 특성상 그다지 내마모성이 좋지 못하다는 단점을 갖는다.In other words, SS41, which is a kind of structural steel, is used to make the shape of a knife, and the cutting edge of the knife is sharply cut to form a blade. However, this has a disadvantage in that the wear resistance is not good.

그렇다고 마모성이 좋은 재질의 특수강을 사용하여 칼을 제조하는 경우는 칼날의 내마모성은 좋아지나, 그다지 내마모성이 필요없는 몸체부까지 고가의 특수강을 사용하는 것은 경제적이지 못하다.However, in the case of manufacturing a knife using a special wear of a good wear material, the wear resistance of the blade is improved, but it is not economical to use expensive special steel up to the body portion that does not require much wear resistance.

따라서 종래에는 상기 칼날부는 내마모성이 좋은 특수강을 사용하고, 칼몸체부는 저렴한 구조강을 사용하기도 하나, 상기 칼날부와 칼몸체부를 서로 접착하는데 있어 칼날부와 칼몸체부 사이에 얇은 동판을 덧대고 상기 동판을 융착시켜 접착시키므로 접착력이 약해 칼날부가 칼몸체부로 부터 쉽게 이탈되는 폐단을 갖는 것이다.Therefore, the blade portion uses a special steel having good wear resistance, and the blade body portion may use an inexpensive structural steel, but in bonding the blade portion and the blade body portion to each other, a thin copper plate is padded between the blade portion and the blade body portion. Since the adhesive force is weak because the adhesive bonds to the blade has a closed end that is easily separated from the blade body.

즉 칼날부의 재질은 특수강이고, 칼몸체부의 재질은 구조강으로 모두 철을 주성분으로 하는 금속인 반면, 이들을 결합하는 접착수단인 동의 재질은 철과는 전혀다른 이종의 재질이기 때문에 칼날부와 칼몸체부가 융착되었다가도 약간의 충격만 가해지면 접착부분이 쉬 분리되어 빈번한 칼날의 파손에 의한 재활용 PVC 분쇄장치의 잦은 고장원인이 되는 폐단을 갖는 것이었다.In other words, the blade part is made of special steel, and the material of the knife body is a structural steel, all of which is a metal mainly composed of iron, whereas the copper material, which is a bonding means for bonding them, is a different material from iron, so the blade part and the knife body Even if the fusion spliced, if a little impact was applied, the adhesive part was easily separated and had a closed end which was a frequent cause of failure of the recycled PVC crusher by frequent blade breakage.

따라서 본 발명은 상기와 같은 종래의 폐단을 해결하기 위해 칼날부는 내마모성이 좋은 특수강을 사용하고, 베이스금속, 즉 칼몸체부는 견고하고 강인한 성질의 구조강을 사용하되 칼몸체부분과 칼날의 결합이 동종의 재질인 철에 의해 접착되도록 하므로써 칼날과 칼몸체부가 쉬 분리되지 않아 내구성이 좋아지므로 오랫동안 사용할 수 있는 재활용 PVC 분쇄용 칼의 제조방법을 제공할 수 있는 것이다.Therefore, in the present invention, in order to solve the above-mentioned conventional end, the blade portion is made of special steel with good wear resistance, and the base metal, ie, the knife body portion, uses a structural steel of solid and tough properties, but the combination of the knife body portion and the blade is the same. It is possible to provide a method of manufacturing a recycled PVC grinding knife that can be used for a long time because the blade and the body part is not easily separated by being bonded by iron, which is a material of the material.

도 1 내지 도 7은 본 발명 재활용 PVC 분쇄용 칼의 제조공정을 보이기 위한 참고도.1 to 7 is a reference diagram for showing the manufacturing process of the present invention recycled PVC grinding knife.

이하 본 발명을 첨부한 도면에 의해 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

본 발명은 먼저 구조강(본 발명에서는 구조강 SS41을 사용하였다)을 베이스금속으로 하여 칼몸체부(10)를 제조하는 단계와, 다음 상기 칼몸체부(10)에서 칼날부가 결합될 부분을 절삭해내는 단계와, 상기 칼몸체부(10)의 칼날결합면(30)에 분철(40)를 뿌리고 미리 칼날결합면(30)에 정확하게 일치하도록 가공하여 둔 특수강(본 발명에서는 특수강 SKS3을 사용하였다)을 재질로 하는 칼날부(20)를 칼날결합면(30)에 밀착시키는 단계와, 상기 칼몸체부(10)와 칼날부(20)을 1100℃의 전기로에 넣고 가열하는 단계와, 상기 가열단계 후 전기로에서 꺼냄과 동시에 기계햄머로 반복적으로 두들겨 충격을 가해 칼날부(20)가 칼몸체부(10)와 결합되도록하는 단계와, 칼날부의 날을 세우기 위해 칼몸체부(10)와 칼날부(20)을 동시에 절삭선(A)을 따라 밀링가공하여 절삭부(B)를 절삭해내는 단계와, 상기 밀링가공된 재활용 PVC 분쇄용 칼(1)을 열처리하는 단계와, 재활용 PVC 분쇄장치에 장착할 수 있도록 홀(50)을 가공하는 단계로 이루어지는 것이다.According to the present invention, a step of manufacturing a knife body portion 10 using structural steel (structure steel SS41 is used in the present invention) as a base metal, and then cutting out a portion to which the blade portion is coupled from the knife body portion 10 is performed. Step and spraying the powdered iron (40) on the blade coupling surface 30 of the knife body portion 10 and the special steel (special steel SKS3 was used in the present invention) that was processed to match exactly the blade coupling surface 30 in advance Step of bringing the blade portion 20 into close contact with the blade coupling surface 30, putting the knife body portion 10 and the blade portion 20 into an electric furnace at 1100 ° C., and heating, in the electric furnace after the heating step. Simultaneously tapping with a mechanical hammer to take out the impact to ensure that the blade portion 20 is coupled to the knife body portion 10, and simultaneously cutting the knife body portion 10 and the blade portion 20 to erect the blade portion. Mill along the line (A) to cut the cutting (B) And a step of heat-treating the milled recycled PVC grinding knife 1, and processing the holes 50 to be mounted on the recycled PVC grinding device.

상기 분철(40)의 재질은 구조강 SS41을 사용하였으며, 상기 재활용 PVC 분쇄용 칼(1)의 열처리단계는 약 950~1000℃의 로에 넣어 기름에 급냉하는 침탄방식을 사용한다. 이때 칼날부(20)의 HR경도는 용도에 따라 56~58의 범위를 유지할 수 있도록 한다.The material of the powdered iron 40 used structural steel SS41, the heat treatment step of the recycled PVC grinding knife (1) uses a carburizing method to quench the oil in a furnace of about 950 ~ 1000 ℃. At this time, the HR hardness of the blade portion 20 to maintain the range of 56 ~ 58 depending on the use.

이처럼 본 발명은 칼날부는 내마모성이 좋은 특수강을 사용하고, 칼몸체부는 견고하고 강인한 성질의 구조강을 사용하되 칼몸체부분과 칼날의 결합이 동종의 재질인 분철에 의해 단접에 의해 접착되도록 하므로써 칼날과 칼몸체부가 쉬 분리되지 않아 내구성이 향상되므로 오랫동안 사용할 수 있으며, 또한 비교적 저렴한 재활용 PVC 분쇄용 칼을 사용자들에게 제공하므로써 사용자의 경제적인 이득을 도모할 수 있는 매우 유용한 발명인 것이다.As described above, the blade portion uses a special wear-resistant special steel, the blade body portion using a rigid and strong structural steel, but the blade body and the blade is bonded to the blade by bonding by the joint of the same material of the same iron powder It can be used for a long time because the durability of the knife body is not separated, and it is a very useful invention that can provide economical benefits to users by providing users with a relatively inexpensive recycled PVC grinding knife.
