Description
본 발명은 구멍모따기용 절삭공구에 관한 것으로, 더욱 구체적으로는 구멍모따기를 하는 절삭공구의 생크 끝에 설치되는 교체형 절삭날 일측에 가이드날을 브레이징 용착하여 절삭부에 일체형으로 구성하여 모따기 작업시에 가이드날에 의해 절삭날이 흔들리지 않고 절삭이 용이하도록 한 것이다.The present invention relates to a cutting tool for chamfering, and more particularly, by brazing and guiding a guide blade to one side of a replaceable cutting edge installed at the shank end of the cutting tool for chamfering to form a unit integrally with the cutting part. The cutting edge is not shaken by the guide blade so that cutting is easy.
종래의 구멍모따기용 절삭공구에서는 생크 끝에 절삭부의 절삭날을 교체형으로 구성하여 절삭날이 마모되면 이를 교체할수 있도록하였으나 절삭날이 흔들리는 등의 문제점이 있었다.In the conventional cutting tool for chamfering, it is possible to replace the cutting edge when the cutting edge is worn by replacing the cutting edge of the cutting portion at the end of the shank, but the cutting edge is shaken.
본 발명은 이러한 문제점을 해결하기 위하여 절삭공구의 생크 끝에 있는 절삭부에 절삭날 고정홈을 형성하여 초경합금으로된 교체형 절삭날을 설치하되 절삭부의 경사면에 삽입홈을 형성하여 그 삽입홈에 가이드날을 끼워 브레이징 용착으로 일체로 고정하여서 된 것이다.In order to solve the above problems, the present invention provides a cutting edge fixing groove at the cutting end at the shank end of the cutting tool to install a replacement cutting edge made of cemented carbide, and forms an insertion groove on the inclined surface of the cutting portion to guide the blade in the insertion groove. It is made by fixing them integrally by brazing welding.
이하 본 발명을 더욱 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in more detail.

경강이나 합금강으로 만든 본체(10)의 생크(11)끝에 절삭부(12)를 구성하되 절삭부(12)의 경사면(13)에 삽입홈(14)을 형성하여 초경합금으로된 가이드날(15)을 끼워 브레이크징 용착으로 일체로 고정하고 절삭부(12)에 형성된 절삭공간부(16) 일측면에 절삭날 고정홈(17)을 형성하여 초경합금으로된 절삭날(18)을 볼트(19) 결합으로 고정시켜 절삭날 교체를 할수 있도록 한 것이다.Guide blade 15 made of cemented carbide by forming a cutting portion 12 at the end of the shank 11 of the body 10 made of hard steel or alloy steel, the insertion groove 14 in the inclined surface 13 of the cutting portion 12 The cutting edges 18 made of cemented carbide to the bolts 19 by forming the cutting edge fixing grooves 17 in one side of the cutting space 16 formed in the cutting portion 12. It is fixed so that cutting edge can be replaced.
상기에서 절삭날(18)은 정삼각형이나 정사각형 형태로 만들어 절삭날(18)의 날부(18a)를 삼면이나 사면을 활용할수 있게하며, 절삭날(18)과 가이드날(15)의 간격은 절삭날(18)의 모따기 작업시에 가이드날(15)이 모따기면에 밀착될수 있는 간격으로 형성하고 가이드날(15)은 경사면(13) 보다 약간 돌출된 상태를 유지토록 한다.The cutting edge 18 is made of a regular triangle or a square shape to enable the blade portion 18a of the cutting edge 18 to utilize three sides or slopes, and the interval between the cutting edge 18 and the guide blade 15 is a cutting edge. At the time of the chamfering operation of 18, the guide blades 15 are formed at intervals that can be in close contact with the chamfered surface, and the guide blades 15 are kept to protrude slightly from the inclined surface 13.
도면중 미설명 부호 19a는 볼트구멍, 20은 공작물, 21은 구멍In the drawings, reference numeral 19a denotes a bolt hole, 20 a workpiece, and 21 a hole.
이와같이된 본 발명은 경강이나 합금강으로 만든 본체(10)의 절삭부(12)에 초경합금으로된 절삭날(18)과 가이드날(15)이 고정되어 도 2의 (나)에서와 같이 공작물(20)의 구멍(21) 모따기를 할때 모서리부분은 절삭날(18)에 의해 절삭이 이루어짐과 아울러 절삭부(12)에 브레이징 용착으로 일체로 고정되어 있는 가이드날(15)은 절삭날(18) 반대편의 모서리부분에 맞닿아서 절삭날(18)이 흔들리지 않고 매끄럽게 절삭되도록 한다.According to the present invention, the cutting blade 18 and the guide blade 15 made of cemented carbide are fixed to the cutting portion 12 of the main body 10 made of hard steel or alloy steel, so that the workpiece 20 may be formed as shown in FIG. When chamfering the hole 21), the edge portion is cut by the cutting edge 18 and the guide blade 15 integrally fixed to the cutting portion 12 by brazing welding is the cutting edge 18. The cutting edge 18 is smoothly cut without being shaken by touching the opposite edge.
이렇게 구멍(21) 모따기 작업을 하게됨과 아울러 절삭날(18)이 마모되면 도3의 (나)에서와 같이 볼트(19) 결합된 절삭날(18)을 분해한 다음 절삭날(18)의 마모되지 않은 또 다른 날부(18a)로 절삭이 이루어지도록 절삭날(18)을 고정한후 절삭작업을 하면 되는 것이다.When the cutting edge 18 is worn while the hole 21 is chamfered as described above, the cutting edge 18 coupled to the bolt 19 is disassembled, and then the wear of the cutting edge 18 is removed. The cutting edge 18 is fixed so that the cutting is performed with another blade portion 18a which is not.
즉, 절삭날(18)을 볼트(19)결합으로 고정시키도록 되어 있으므로 절삭날(18) 형태가 정삼각형이거나 정사각형일때에는 삼면 또는 사면의 마모되지 않은 날부(18a)를 선택하여 고정하면 되므로 그 만큼 절삭날(18)을 효율적으로 활용할수 있게 되고 절삭날(18)의 날부(18a)전면이 완전마모되면 새로운 절삭날(18)을 교체하여 사용하면 되는 것이다.That is, since the cutting edge 18 is fixed to the bolts 19, the cutting edge 18 is a regular triangle or a square, so that the non-wearing edge portion 18a of three or four sides may be selected and fixed. When the cutting edge 18 can be utilized efficiently and the front surface of the blade portion 18a of the cutting edge 18 is completely worn out, the new cutting edge 18 can be replaced and used.
이와같이 본 발명의 구멍모따기용 절삭공구는 교체형 절삭날의 일측에 설치되는 가이드날이 절삭부에 일체로 용착된 구성으로 절삭날이 흔들리지 않고 정밀한 절삭작업이 이루어지게 하므로 모따기 상태가 좋은 이점이 있는 것이다.As described above, the cutting tool for chamfering of the present invention has a good chamfering state because the guide blade installed on one side of the replaceable cutting edge is welded integrally to the cutting part so that the cutting edge is not shaken and precise cutting operation is performed. will be.
