Description

Gear type portable manual hacksaw cutter {Portable saw}

본 발명은 쇠톱절단기에 관한 것으로, 특히 기어를 이용하여 수동식으로 쇠톱을 작동시킬 수 있는 기어식 휴대용 쇠톱절단기에 관한 것이다.The present invention relates to a hacksaw cutter, and more particularly, to a gear-type portable hacksaw cutter that can operate a hacksaw manually using a gear.

기존에 경도가 높은 금속을 절단하는 방법은 그라인더를 이용하거나 수작업으로 줄톱을 이용하여 절단한다. 선반이나 밀링등 자동 절단을 할 수 있는 기계장치들에 설치된 절단날은 원형으로 형성되어 절단날을 회전시킴으로서 재료를 절단한다.Conventionally, the method of cutting hard metals is performed by using a grinder or a file saw by hand. Cutting blades installed on machines capable of automatic cutting, such as lathes and milling, are formed in a circular shape to cut the material by rotating the cutting blade.

금속재료를 절단함에 있어서는 필요에 따라 회전날이 아닌 줄톱과 같이 전후이동만으로 절단해야 하는 상황이 발생하게 된다.When cutting a metal material, a situation arises in that it is necessary to cut only by moving back and forth, such as a file saw, not a rotary blade, if necessary.

그러나 기존에는 전후 이동만으로 금속재료를 절단하는 방법은 줄톱을 이용하는 것이 전부이다. 따라서 절단작업에 많은 시간이 소요되고, 안전사고의 위험 및 비균일성으로 인하여 절단재료의 품질을 떨어뜨리는 문제점이 있었다.However, conventionally, the only way to cut a metal material by moving back and forth is to use a file saw. Therefore, the cutting operation takes a lot of time, there was a problem of reducing the quality of the cutting material due to the risk and non-uniformity of the safety accident.

본 발명은 전술한 바와 같은 문제점을 해결하기 위하여 안출한 것으로서, 수작업으로 진행하던 절단작업을 수동으로 하기 위한 것이다.The present invention has been made in order to solve the problems described above, and is for manually performing the cutting operation proceeded manually.

상기의 목적을 달성하기 위하여 각종 절단부속품이 장착되는 툴커버(12)가 형성되고, 상기 툴커버의 후미 일측에는 회전손잡이가 설치되며, 상기 회전손잡이에는 제1대기어와 제1소기어가 형성되고, 상기 제1대기어에 제2대기어가 맞물려 연결되고, 제1소기어에 제2소기어가 맞물려 연결되며, 제2소기어에는 제3소기어 맞물려 연결되고, 상기 제2대기어의 중심에서 일정거리 편심시켜 제1절단톱의 단부가 연결되고, 상기 제3소기어의 중심에서 일정거리 편심시켜 제2절단톱의 일단부가 연결되며, 상기 제1절단톱과 제2절단톱 사이에 가이드박판이 설치되고, 상기 툴커버의 끝단에 사출성형부가 삽입 결합된 것과, 상기 툴커버의 후미 일단에 부속장비를결합하여 사용할 수 있는 도킹홀을 형성한 것을 특징으로 하는 기어식 휴대용 수동식 절단기를 제공한다.In order to achieve the above object, a tool cover 12 having various cutting accessories mounted thereon is formed, and one end of the tool cover is provided with a rotation knob, and the first and second gears are formed on the rotation knob. A second gear is engaged with the first gear, and a second gear is engaged with the first gear, and a third gear is engaged with the second gear, and at the center of the second gear. The end of the first cutting saw is connected by eccentric distance, and the end of the second cutting saw is connected by eccentric distance from the center of the third gear, and the guide sheet is between the first cutting saw and the second cutting saw. Is provided, the injection molding unit is inserted and coupled to the end of the tool cover, the rear end of the tool cover provides a gear type portable manual cutter characterized in that the docking hole which can be used by combining the accessory equipment .

After the hole (not shown) is formed at one end of the second cutting saw 18, the hole is inserted into the protrusion of the third small gear 34 to be installed.

상기한 제1절단톱(16)과 제2절단톱(18) 사이에는 양쪽 절단톱이 제2대기어(28)나 제3소기어(34)의 힘을 전달시키기 위하여 회전시 이탈방지를 위하여 가이드 박판(20)을 삽입하여 설치한다.Between the first cutting saw 16 and the second cutting saw 18, both cutting saws to prevent the separation during rotation to transfer the force of the second large gear 28 or the third small gear 34 Insert the guide sheet 20 to install.

가이드 박판(20)과 그 양면으로 접하여 있는 제1절단톱(16) 및 제2절단톱(18)에 길이방향으로 슬롯홀(미도시)이 형성되고, 이 슬롯홀의 길이는 제1절단톱(16) 및 제2절단톱(18)의 왕복 이동방향 길이 보다 길게 형성한다.A slot hole (not shown) is formed in the longitudinal direction in the guide cutting plate 20 and the first cutting saw 16 and the second cutting saw 18 which are in contact with both surfaces thereof, and the length of the slot hole is the first cutting saw ( 16) and longer than the length of the reciprocating movement direction of the second cutting saw 18.

슬롯홈의 중앙에는 제1절단톱(16)과 제2절단톱(18)의 수직선상의 유동을 막기 위하여 수평 가이드핀(22)이 설치되고, 이 수평 가이드핀(22)의 양단을 툴커버(12)의 면에 결합시켜 형성하며, 이 수평 가이드핀(22)은 상부에서 하부로 가면서 단면이 약간 작아지게 형성한다.In the center of the slot groove, horizontal guide pins 22 are installed to prevent the first cutting saw 16 and the second cutting saw 18 from flowing in a vertical line, and both ends of the horizontal guide pins 22 are provided with a tool cover ( It is formed by coupling to the surface of 12), the horizontal guide pin 22 is formed to be slightly smaller in cross section going from the top to the bottom.

툴커버(12)의 가장 끝단에는 제1절단톱(16)과 제2절단톱(18)이 통과하는 구멍이 형성되어 있고, 툴커버(12)의 재질은 플라스틱으로 제작되는데, 이 플라스틱이 절단톱에 의하여 파손이 되는 것을 방지하기 위하여 금속류의 사출성형물(40)을 삽입하여 설치한다.The first end of the tool cover 12 is formed with a hole through which the first cutting saw 16 and the second cutting saw 18 pass, and the material of the tool cover 12 is made of plastic, which is cut. In order to prevent damage to the saw by inserting the metal injection molding 40 is installed.

상기한 툴커버(12)의 후미에는 도킹홀(42)을 형성하고, 이 도킹홀(42)은 사용자의 필요에 따라 어깨 받침대(미도시)와 같은 부속장비를 연결하여 절단작업을 용이하게 할 수 있게 한다.A docking hole 42 is formed at the rear of the tool cover 12, and the docking hole 42 may be connected to an accessory device such as a shoulder support (not shown) to facilitate cutting operation according to a user's need. To be able.

상기한 바와 같은 구성의 작용은 회전손잡이(14)를 돌리면 회전손잡이(14)와 연결된 제1대기어(26)와 제1소기어(30)가 연동하여 회전한다. 제1대기어(14)가 회전하면 제1대기어와 맞물려 결합된 제2대기어(28)가 회전하고, 제2대기어(28)에 연결된 제1절단톱(16)이 도 2에 도시된 바와 같은 궤적을 그리면서 작용점 "A"를 중심으로 밀고 당기는 운동을 한다.As described above, when the rotary knob 14 is rotated, the first large gear 26 and the first gear 30 connected to the rotary knob 14 rotate together. When the first gear 14 rotates, the second gear 28 engaged with the first gear is rotated, and the first cutting saw 16 connected to the second gear 28 is shown in FIG. While drawing the trajectory as shown in the bar, push and pull around the working point "A".

제1소기어(30)의 회전으로 제2소기어(32)가 제1소기어(30)의 회전방향과 반대로 회전하고, 제2소기어(32)와 맞물린 제3소기어(34)는 제2소기어(32)의 회전방향과 반대로 회전한다. 즉 제2대기어(28)의 회전방향과 항상 반대로 회전하게 된다. 제3소기어(34)에 연결된 제2절단톱(18)이 도 2에 도시된 바와 같은 궤적을 그리면서 작용점 "A"를 기준으로 밀고 당기는 운동을 하게 된다.As the first gear 30 rotates, the second gear 32 rotates in the opposite direction to the rotation direction of the first gear 30, and the third gear 34 engaged with the second gear 32 is Rotate opposite to the rotation direction of the second gear (32). That is, the rotation is always reversed to the rotation direction of the second gear (28). The second cutting saw 18 connected to the third small gear 34 performs a pushing and pulling motion based on the operating point “A” while drawing the trajectory as shown in FIG. 2.

여기서 수평가이드핀(22)은 제1절단톱과 제2절단톱이 동작하면서 수직선상의 유동을 막고, 툴커버(12)의 가장 끝단에 설치된 사출성형부(40)는 제1절단톱(16)과 제2절단톱(18)이 왕복하면서 접촉하는 부분의 파손을 방지한다.Wherein the horizontal guide pin 22 is the first cutting saw and the second cutting saw to prevent the flow in the vertical line, the injection molding portion 40 installed at the end of the tool cover 12 is the first cutting saw 16 And the second cutting saw 18 reciprocate to prevent breakage of the contact portion.

전술한 바와 같은 본 발명은 수작업에 따른 비효율성을 제거하고, 수동식 작업에 의하여 정밀한 절단작업을 행할 수 있으며, 작업자가 직접 절단톱을 사용하지 않고, 간접적으로 절단톱을 절단대상물에 사용하므로 작업자의 안전을 확보할 수 있다.The present invention as described above can remove the inefficiency according to the manual work, and can perform precise cutting work by manual operation, and the operator does not use the cutting saw directly, and indirectly uses the cutting saw for the cutting object, Safety can be secured.
