Description
본 고안은 휨방지 가드를 구비한 쇠톱에 관한 것으로서, 보다 상세하게는 쇠톱이 절단물에 자리잡을 때까지, 쇠톱의 휨을 방지하도록 직선홈이 형성된 휨방지 가드를 구비한 쇠톱이다.The present invention relates to a hacksaw provided with an anti-bending guard, and more particularly, to a hacksaw provided with an anti-bending guard in which a straight groove is formed to prevent bending of the hacksaw until the hacksaw is settled in the cutting.
종래의 쇠톱은 쇠톱날의 양단을 지지하기 위한 프레임과, 절단작업을 위해 힘을 가할 수 있는 손잡이와, 쇠톱날의 일측 단부에서 쇠톱날을 당기어 고정하는 조정너트와, 쇠톱날의 타측 단부를 고정하는 핀 등을 포함하여 이루어졌다.The conventional hacksaw has a frame for supporting both ends of the hacksaw blade, a handle capable of applying force for cutting work, an adjustment nut for pulling and fixing the hacksaw blade at one end of the hacksaw blade, and the other end of the hacksaw blade. And pins for fixing.
종래의 쇠톱은 초기 절단작업시 횡방향으로 휘어지면서 쇠톱날이 전단되는 경우가 자주 있었다. 이러한 이유는 초기 절단 작업시에 쇠톱날이 절단물을 절삭하고 절단물 내에 진입하지 못해 일어나는 경우였다. 즉, 쇠톱날이 절단물을 절삭하고 직선의 절단로를 내어 절단물에 일정깊이 진입하였을 경우에는, 쇠톱날의 양측면이 절단물의 절단로 내측면에 지지되어 쇠톱의 휨이 방지되지만, 절삭 초기에는 쇠톱날이 절삭물에 지지되지 못하기 때문이었다.Conventional hacksaws often have a hacksaw blade sheared laterally during initial cutting. This was the case when the hacksaw blade cuts the cut and fails to enter the cut during the initial cutting operation. That is, when the hacksaw blade cuts the cutting object and enters the cutting object with a straight cutting path, both sides of the hacksaw blade are supported on the inner side by the cutting of the cutting material to prevent bending of the hacksaw. The hacksaw blade was not supported by the cutting.
이와 같이 종래의 쇠톱은 쇠톱날이 절단물에 일정 깊이로 진입할 때까지는 쇠톱날의 휨을 방지하지 못하여 쇠톱날이 전단되는 문제점이 있었다.As described above, the conventional hacksaw has a problem that the hacksaw blade is not sheared until the hacksaw blade enters the cutting object at a predetermined depth.
본 고안의 목적은 이러한 문제점을 해결하고자 안출된 것으로서, 쇠톱날이 절단물에 일정 깊이로 진입할 때까지, 쇠톱날의 측면을 지지하여 쇠톱날의 휨을 방지함으로써 전단이 방지되는 쇠톱을 제공함에 있다.An object of the present invention is to provide a hacksaw that is prevented from shearing by supporting the side of the hacksaw blade to prevent the bending of the hacksaw blade until the hacksaw blade enters a certain depth to solve this problem. .

And an adjustment nut 20 for pulling and fixing the hacksaw blade 1 at one end thereof, and a pin 25 for fixing the other end of the hacksaw blade 1 to which the hacksaw blade 1 is fixed. A plurality of through holes 30a and 30c having bushings 31a and 32c are formed in the frame 5, and a locking end 35 is formed in each of the through holes 30a and 30c and a thread 38 is formed at a lower end thereof. Is formed so that the supporting rods 32a and 32c are caught by the upper surface of the frame 5, and the thread 38 of each of the supporting rods 32a and 32c is prevented from bending of the hacksaw blade 1. A guard 40 having a linear groove 42 is coupled to the upper portion of 1), and springs 45a and 45c for applying an elastic force to the guard 40 are installed on the support rods 32a and 32c.
도 4 및 도 5에 도시된 바와 같이 상기 프레임(5)에는 부싱(31b)을 가지는 관통공(30b)이 더 형성되어, 상부에 나선(50)이 형성되고 하부가 가드(40)에 결합되며 스프링(45b)이 설치된 조절봉(47)이 끼워지고, 상기 조절봉(47)의 나선(50)에는 상기 지지봉(32a, 32c) 및 조절봉(47)의 스프링(45a, 45b, 45c)을 압축하면서 상기 가드(40)를 상방향으로 이동시켜 프레임(5)에 쇠톱날(1)을 끼우거나 이탈시킬 수 있도록 나비너트(60)가 결합된다.As shown in FIGS. 4 and 5, the through-hole 30b having the bushing 31b is further formed in the frame 5, the spiral 50 is formed on the upper portion, and the lower portion is coupled to the guard 40. An adjustment rod 47 having a spring 45b is fitted therein, and the support rods 32a and 32c and springs 45a, 45b and 45c of the adjustment rod 47 are inserted into the spiral 50 of the adjustment rod 47. The butterfly nut (60) is coupled to move the guard (40) upward while inserting it into or out of the frame (5).
이하, 본 고안에 따라 쇠톱날(1)을 프레임(5)에 설치하여 절삭물을 절단하는 과정을 설명한다.Hereinafter, the process of cutting the cutting by installing the hacksaw blade 1 in the frame 5 according to the present invention.
작업자는 프레임(5)의 중앙에 위치한 조절봉(47)의 나비너트(60)를 돌려 가드(40)가 스프링(45a, 45b, 45c)을 압축하면서 상방향으로 이동하게 하고, 쇠톱날(1)을 프레임(5)의 양단부에 설치하여 조정너트(20)를 돌려 쇠톱날(1)을 고정시킨다. 다시, 조절봉(47)의 나비너트(60)를 돌려 가드(40)가 하방향으로 이동하면서 쇠톱날(1)의 상부가 가드(40)의 직선홈(42)에 끼워지게 한다.The operator rotates the butterfly nut 60 of the adjusting rod 47 located in the center of the frame 5 so that the guard 40 moves upward while compressing the springs 45a, 45b, and 45c, and the hacksaw blade 1 ) Is installed at both ends of the frame (5) to turn the adjusting nut (20) to fix the hacksaw blade (1). Again, by turning the butterfly nut 60 of the adjustment bar 47 to move the guard 40 in the downward direction so that the upper portion of the hacksaw blade 1 is fitted into the linear groove 42 of the guard 40.
작업자는 손잡이(10)를 잡고 쇠톱날(1)을 절삭물에 올려 놓은 후, 쇠톱날(1)을 당기고 밀면서 절삭물을 조금씩 자르기 시작한다. 이때, 쇠톱날(1)이 절삭물을 절삭하면서 절삭물 내부로 진입함에 따라 가드(40)의 하면은 절삭물의 외부면에 지지되고 쇠톱날(1)은 쇠톱날(1)의 상부가 가드(40)의 직선홈(42)을 이탈할 때까지 횡방향 굽힘으로부터 가드(40)에 의해 보호된다.The operator grasps the handle 10 and places the hacksaw blade 1 on the workpiece, and then starts cutting the workpiece little by little while pulling and pushing the hacksaw blade 1. At this time, as the hacksaw blade 1 enters the cutting material while cutting the cutting material, the lower surface of the guard 40 is supported on the outer surface of the cutting material, and the hacksaw blade 1 has an upper portion of the hacksaw blade 1. The guard 40 is protected from the lateral bending until the straight groove 42 of the 40 is released.
이상에서와 같이 본 고안에 따른 휨방지 가드를 구비한 쇠톱은 쇠톱날이 절단물에 일정깊이 진입할 때까지, 쇠톱날의 측면을 지지하여 쇠톱날의 휨을 방지함으로써 쇠톱날의 전단을 막는 효과를 얻을 수 있다.As described above, the hacksaw provided with the anti-bending guard according to the present invention supports the side of the hacksaw blade to prevent the bending of the hacksaw blade, thereby preventing the shear of the hacksaw blade, until the hacksaw blade enters a predetermined depth. You can get it.
이상에서 본 고안은 기재된 구체예에 대해서만 상세히 설명되었지만, 본 고안의 기술사상 범위 내에서 다양한 변형 및 수정이 가능함은 당업자에게 있어서 명백한 것이며, 이러한 변형 및 수정이 첨부된 실용신안등록청구범위에 속함은 당연한 것이다.Although the present invention has been described in detail only with respect to the embodiments described, it will be apparent to those skilled in the art that various modifications and variations are possible within the technical spirit of the present invention, and such modifications and modifications belong to the appended claims of utility model registration. It is natural.
