본 발명은 손톱깍기의 누름편의 제조방법에 관한 것으로, 특히 누름편 일단의 저면에 지지강도를 높이기 위한 삼각돌기와 지지봉에 삽입되는 힌지부를 일체로 형성한 손톱깍기의 누름편 제조방법에 관한 것이다.The present invention relates to a method for manufacturing a pressing piece of nail clippers, and more particularly, to a pressing piece manufacturing method of nail clippers in which a triangular protrusion for increasing support strength and a hinge portion inserted into a support bar are integrally formed on the bottom of one end of the pressing piece.

일반적으로는 손톱깍기는 제3도(a)에 나타낸 바와 같이, 일단에 대향 절곡된 절단날(200a)(201b)를 갖는 상, 하부 탄성편(200)(201)과 상기 절단날(200a)(201b) 내측쪽의 상, 하부 탄성편(200)(201)에 천공된 홀(202)을 수직관통하여 상기 탄성편(200)(201)을 지지하는 지지봉(203) 및 상기 지지봉(203)일측의 개구부(204)에 삽입 결합되는 힌지부(107)와 일측면에 원추형 돌기부(208)를 갖는 누름편(206)으로 구성되어 있는 것이 있다.Generally, the nail clipper has upper and lower elastic pieces 200 and 201 and the cutting blades 200a having cutting blades 200a and 201b that are bent at one end as shown in FIG. 3 (a). A support rod 203 and the support rod 203 which support the elastic pieces 200 and 201 by vertically passing the holes 202 drilled into the upper and lower elastic pieces 200 and 201 on the inner side. The hinge piece 107 inserted into and coupled to the opening 204 on one side and the pressing piece 206 having the conical protrusion 208 on one side thereof are constituted.

이와 같이 구성된 상기 누름편(206)은 철판의 일단에 홀(109)을 절개 형성한 후, 원추형 돌기(208)가 돌출되도록 압압하여 형성한 것이므로 외관상 고급스럽지 못하고 또한 원추형 돌기(208)가 둥글해서 지지력이 약하여 미끄러지기 쉬운 결점이 있었다.The pressing piece 206 configured as described above is formed by cutting the hole 109 at one end of the iron plate and pressing the conical protrusion 208 so as to protrude, and thus the conical protrusion 208 is round. There was a weak bearing capacity and slippery defects.

손톱깍기의 또다른 종래예로는 제3도(b)에 도시된 바와 같이 탄성력을 가지는 탄성편(101)(101')을 상, 하로 형성하고 탄성편(101)(101')의 일단은 서로 대향되게 절곡시켜 절단날(102)(102')을 형성하며 상기 탄성편(101)(101')의 타단은 결합부재(103)에 의해 서로 고정 결합되어 있다.As another conventional example of nail clippers, as shown in FIG. 3 (b), the elastic pieces 101 and 101 'having elastic force are formed up and down, and one end of the elastic pieces 101 and 101' is formed. The cutting blades 102 and 102 'are bent to face each other, and the other ends of the elastic pieces 101 and 101' are fixedly coupled to each other by the coupling member 103.

상기 탄성편(101)(101')의 일단에 각각 형성된 절단날(102)(102')의 내측쪽에 삽입공(104)(104')을 각각 형성하여 상부에 힌지핀 삽입공(108')이 가로로 관통된 지지봉(105)을 하부로부터 수직으로 삽입힌다.Hinge pin insertion holes 108 'are formed on the upper portions of the elastic pieces 101 and 101' by forming insertion holes 104 and 104 'on inner sides of cutting edges 102 and 102', respectively. The horizontally penetrating support rod 105 is inserted vertically from the bottom.

다음에, 상부 탄성편(101)의 상면에서 누름편(106)의 삼각돌기(107)의 양측에 가로로 형성된 힌지핀 삽입공(108)을 상기 지지봉(105) 상부의 힌지핀 삽입공(108')과 일치시킨 다음, 힌지핀(109)을 상기 힌지핀 삽입공(108)(108')에 삽입시키고 나서 지지봉(105)과 누름편(106)을 결합하고 있다.Next, a hinge pin insertion hole 108 formed horizontally on both sides of the triangular protrusion 107 of the pressing piece 106 on the upper surface of the upper elastic piece 101 is hinge pin insertion hole 108 above the support rod 105. ') And then, the hinge pin 109 is inserted into the hinge pin insertion holes 108 and 108', and then the supporting rod 105 and the pressing piece 106 are coupled.

상기 누름편(106)은 금속판이 아닌 금속봉을 압착시켜 성형한 것이어서 누름편 저면돌기가 삼각돌기로서 형성되고, 그 아래면이 평면이기 때문에 누름편을 눌렀을 때 지지력이 좋고 미끄러지지 않으며 안정감을 주는 장점은 있었다.Since the pressing piece 106 is formed by pressing a metal rod instead of a metal plate, the pressing piece bottom projection is formed as a triangular projection, and since the bottom surface is flat, the supporting force is good when the pressing piece is pressed. there was.

그러나, 상기 누름편(106)을 탄성편(101)(101')과 결합하기 위해서는 지지봉(105)의 상부에 힌지핀 삽입공(108')을 형성하고, 또 누름편(106)의 삼각돌기에 힌지핀 삽입공(108)을 형성한 다음, 힌지핀(109)을 상기 힌지핀 삽입공(108)(108')에 삽입시켜야 하고 또한 누름편(106)의 제조공정도 삼각돌기(107)를 형성한 후, 삽입공(108)을 형성하여야 하므로, 작업이 복잡하고, 조립시 힌지핀(109)을 삽입공(108)(108')에 삽입시켜야 하는 등의 많은 작업공정을 필요로 하므로, 다수의 인력을 필요로 하며, 또한 힌지핀(109)이 삽입공(108)(108')에서 이탈되는 등의 여러가지 문제점이 있었다.However, in order to couple the pressing piece 106 with the elastic pieces 101 and 101 ', a hinge pin insertion hole 108' is formed in the upper portion of the supporting rod 105, and the triangular protrusion of the pressing piece 106 is formed. After the hinge pin insertion hole 108 is formed in the hinge pin 109, the hinge pin insertion hole 108 and 108 'must be inserted into the manufacturing process of the pressing piece 106. After forming the, since the insertion hole 108 should be formed, the work is complicated, and requires a lot of work processes such as the hinge pin 109 to be inserted into the insertion hole (108, 108 ') during assembly It requires a large number of manpower, and also has a variety of problems such as the hinge pin 109 is separated from the insertion hole (108, 108 ').

그래서, 손톱깍기의 누름편이 고급스럽고 누름편 저면돌기가 안정감을 갖도록 하기 위하여 금속봉을 단조 가공(鍛造加工)하여 삼각돌기(107)의 힌지핀(109)을 별도로 결합할 필요없이 힌지핀 부위가 삼각돌기부와 일체가 되도록 삼각돌기부에 홀을 천공하려고 시도하였으나 삼각돌기의 두께가 두껍기 때문에 홀을 천공한다는 것은 현재의 기술로는 불가능하였다.Therefore, in order to ensure that the pressing piece of the nail clipper is luxurious and the pressing piece bottom projection has a sense of stability, the hinge pin portion is triangulated without forging the hinge pin 109 of the triangular protrusion 107 separately by forging a metal rod. Attempts were made to drill holes in the triangular protrusions so as to be integral with the protrusions, but it was impossible to drill holes because of the thickness of the triangular protrusions.

따라서 상기와 같은 문제점을 해소하기 위하여 삼각돌기에 힌지부가 일체부로 된 누름편을 제조하되, 제4도에 도시된 바와 같이 일정한 두께를 가지는 철판을 단조가공(鍛造加工)하여 누름편(106)의 일단양측면에 삼각돌기(107)가 돌출형성되도록 하고, 상기 삼각돌기(107)사이에는 홀(11)을 천공하여 힌지핀(111)이 일체적으로 형성되도록 한 후 측면으로 돌출된 삼각돌기(107)를 한쪽으로 절곡시켜서 상기 삼각돌기(107)가 누름편(106)의 지렛대 역할을 하도록 제조한 예도 있다.Therefore, in order to solve the problems as described above, the pressing piece of the hinge portion integrally manufactured to the triangular protrusion, as shown in Figure 4 by forging a steel plate having a certain thickness (鍛造 加工) of the pressing piece 106 The triangular protrusion 107 is formed to protrude on both sides, and a hole 11 is formed between the triangular protrusions 107 so that the hinge pin 111 is integrally formed, and then the triangular protrusion 107 protrudes to the side. ) By bending to one side, the triangular protrusion 107 is also manufactured to act as a lever of the pressing piece 106.

그런데, 이와 같이 구성된 누름편(106)은 삼각돌기(107)가 누름편(106)일단의 전체에 일체적으로 형성되어 있지 않아 누름편(106) 일단의 양측으로만 하향 돌출형성되어 있으므로, 누름편(106)을 탄성편(101)(101')과 결합해서 사용할 때에 누름편(106)을 누르면 하향돌출된 삼각돌기(107)의 강도가 약하여 그 지지강도를 보강하기 위하여 돌출형성된 삼각돌기(107) 부위만을 열처리하여야만 한다.By the way, the pressing piece 106 configured in this way is not formed integrally with the entire end of the pressing piece 106, the triangular protrusion 107 is projected downward only on both sides of one end of the pressing piece 106, When the piece 106 is used in combination with the elastic pieces 101 and 101 'and the pressing piece 106 is pressed, the strength of the downwardly protruding triangular protrusion 107 is weak, so that the triangular protrusion protruding to reinforce its supporting strength ( 107) Only the part should be heat treated.

이와 같은 누름편(106)은 간편히 제조할 수 있고, 누름편(106)과 탄성편(101)(101')에 삽입된 지지봉(105)도 그 상부에 힌지핀 삽입공 대신 개방된 걸고리부(미도시)를 형성하여 그 걸고리부에 누름편(106)의 힌지핀(111)을 걸어서 간단히 결합할 수 있으며, 또한 누름편(106)과 지지봉(105)의 분해결합이 용이하고 힌지핀(111)의 이탈도 방지할 수 있는 장점을 가지고 있으나, 돌출형성된 삼각돌기(107)를 열처리하여야 하므로, 고도의 열처리 기술을 필요로 하고, 또 누름편(106)과 동일선상으로 제조된 삼각돌기(107)를 절곡시켜야 하는 문제점을 가지고 있었다.The pressing piece 106 can be easily manufactured, and the supporting rod 105 inserted into the pressing piece 106 and the elastic piece 101 (101 ') also has an open hook portion (instead of a hinge pin insertion hole). (Not shown) can be easily coupled by hooking the hinge pin 111 of the pressing piece 106 to the hook portion, and also easy to disassemble and combine the pressing piece 106 and the supporting rod 105 and the hinge pin 111. ), But also has a merit that can prevent the separation of the protruding triangular protrusion 107, it requires a high heat treatment technique, and the triangular protrusion (107) manufactured in the same line as the pressing piece 106 Had a problem to bend).

본 발명은 상기 여러가지 문제점을 감안해서 이루어진 것으로서, 본 발명의 목적은 누름편을 단조공정에 의해 용이하게 대량 제조할 수 있는 손톱깍기의 누름편 제조방법을 제공하는데 있다.The present invention has been made in view of the above-described various problems, and an object of the present invention is to provide a method for manufacturing a presser clip of a nail clipper, which can be easily mass-produced by a forging step.

이하, 본 발명의 일실시예에 의한 손톱깍기의 누름편에 대하여 첨부도면을 참조하면서 상세히 설명한다.Hereinafter, the pressing piece of the nail clipper according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

본 발명에 의한 손톱깍기는 탄성력을 가지는 상,하부 탄성편(1)(1')의 일측을 서로 대향되게 절곡시켜서 절단날(2)(2')을 형성함과 동시에, 타측을 결합부재(3)에 의해 결합한다.Nail clipper according to the present invention by bending one side of the upper and lower elastic pieces (1) (1 ') having an elastic force to face each other to form a cutting blade (2) (2'), and the other side of the coupling member ( Combined by 3).

다음에, 상기 탄성편(1)(1')의 일측에 형성된 절단날(2)(2')의 내측쪽에 삽입공(4)(4')을 각각 형성하여 지지봉(5)을 삽입한 후, 상기 상부탄성편(1)의 상부면에 노출된 지지봉(5)을 누름편(6)에 형성된 홀(7')에 삽입함과 동시에 상기 누름편(6)의 걸림대(10)를 상기 연결봉(5)에 형성된 상기 홈(5')에 삽입해서 손톱깍기를 조립한다.Next, insertion holes 4 and 4 'are respectively formed on the inner side of the cutting blades 2 and 2' formed on one side of the elastic piece 1 and 1 'to insert the supporting rods 5, respectively. And inserting the support rod 5 exposed on the upper surface of the upper elastic piece 1 into the hole 7 'formed in the pressing piece 6 and simultaneously attaching the catch 10 of the pressing piece 6 to the connecting rod. The nail clipper is assembled by inserting it into the groove 5 'formed in (5).

상기 손톱깍기의 누름편(6)은 삼각홈(15) 및 평면홈(14)이 일체적으로 형성된 단위금형(M1)(M2)(M3)......형태가 연속적으로 반복되다가 일정위치의 단위금형(Mn)에는 펀칭홈(9)이 형성된 하부금형(11')의 초기금형(M1)에 금속봉(12)을 놓은 다음, 상부금형(111)에 의해 압압하고, 상기 1차 단조된 상기 금속봉(12)을 금형(M2, M3....)순차적으로 단조가공하고, 펀칭홀(9)이 형성된 하부금형(11)에서 상부금형(11)의 펀칭핀(13)에 의해 누름편(6)의 삼각돌기(7)형성부분에 1차는 약간 작은 홀을 천공한다.The pressing piece 6 of the nail clipper is formed in a unit mold (M1) (M2) (M3) ... continuously formed with the triangular groove (15) and the flat groove (14) integrally repeated In the unit mold Mn at the position, the metal rod 12 is placed in the initial mold M1 of the lower mold 11 'having the punching groove 9 formed thereon, and then pressed by the upper mold 111, and the first forging is performed. The metal rods 12 are sequentially forged, and pressed by the punching pins 13 of the upper mold 11 in the lower mold 11 having the punching holes 9 formed therein. The primary drills a small hole in the triangular projection 7 forming portion of the piece 6.

다음에, 상기 상부금형(11)의 펀칭핀(13)에 의해 천공된 작은 홀을 하부금형(Mn')에서 상부금형(11)의 펀칭핀(13)에 의해 크게 확개하면서 홀(7') 및 힌지부(10)를 형성함과 동시에, 금속살을 일측으로 밀면서 삼각돌기(107)를 일체적으로 누름편(106)에 형성해서 제조한다.Next, the hole 7 'is greatly enlarged by the punching pin 13 of the upper mold 11 from the lower mold Mn' through the small hole drilled by the punching pin 13 of the upper mold 11. And while forming the hinge portion 10, the triangular projection 107 is integrally formed on the pressing piece 106 while pushing the metal flesh to one side to manufacture.

그리고, 또 다른 방법으로는 상, 하의 압압로울어의 사이에 재료인 금속봉(12)을 삽입하여 누름편(6)이 형성되도록 하는 방법으로 상부로울러에 누름편(6)과 동일한 형상의 돌기를 형성하고 하부로울러에는 상부로울러에 형성된 돌기와 대향되는 위치에 누름편(6)과 동일한 형상의 삽입홈을 형성하되, 삽입홈의 일측에서 삼각돌기(7)가 형성되도록 삼각홈을 형성하고 삼각홈에는 힌지부(10)를 형성하기 위한 홀(7')가 공용돌기를 돌출 형성하여 누름편을 제조 가공하여도 무방한 것이다.In another method, a protrusion having the same shape as the pressing piece 6 is formed on the upper roller by inserting a metal rod 12, which is a material, between the upper and lower pressing rollers so that the pressing piece 6 is formed. And the lower roller is formed with an insertion groove having the same shape as the pressing piece 6 at a position opposite to the protrusion formed in the upper roller, but a triangular groove is formed so that a triangular protrusion 7 is formed at one side of the insertion groove. The hole 7 ′ for forming the hinge portion 10 may protrude to form a shared protrusion to manufacture the pressing piece.

상기와 같이 제조되는 본 발명의 누름편(6)의 제조는 금속봉(12)을 단조하여 제조하면서도 두꺼운 삼각돌기(7)의 형성과 홀(7')의 형성이 연속적인 상, 하부금형(11)(11')에 의해 단계적으로 이루어지므로 힌지부(10)가 일체로 형성된 상태로 펀칭이 가능할 뿐만 아니라, 삼각돌기(7)가 누름편(6)의 본체와 일체로 형성되어짐과 동시에 홀(7')과 힌지부(10)가 하나의 공정에서 형성된다.In the manufacturing of the pressing piece 6 of the present invention manufactured as described above, the upper and lower molds 11 are formed by continuously forming the thick triangular protrusions 7 and forming the holes 7 'while forging the metal rod 12. 11 '), the punching can be performed in a state in which the hinge portion 10 is integrally formed, and the triangular protrusion 7 is formed integrally with the main body of the pressing piece 6, and at the same time, 7 ') and hinge portion 10 are formed in one process.

따라서, 누름편(6)을 제조하기 위한 작업공정이 단축되면서 제작이 용이하며 또한 누름편(6)의 일측에 형성되는 삼각돌기(7)가 누름편(6)의 본체와 일체로 형성되므로, 손톱깍기의 누름편(6)을 눌렀을 때 삼각돌기(7)가 누름편(6)을 누르는 힘을 충분히 지지할 수 있는 것이다.Therefore, since the work process for manufacturing the pressing piece 6 is shortened and easy to manufacture, the triangular protrusion 7 formed on one side of the pressing piece 6 is integrally formed with the main body of the pressing piece 6, When pressing the pressing piece (6) of the nail clipper triangular projection (7) is enough to support the pressing force of the pressing piece (6).

앞에서 설명한 바와 같이 본 발명에 따른 손톱깍기의 누름편 제조방법에 의하면, 금속봉을 연속적으로 상,하부금형에 의해 단조해서 제조함과 동시에, 삼각돌기에 홀과 힌지부를 동시에 형성하므로, 누름편을 용이하게 대량 제조할 수 있다는 매우 뛰어난 효과가 있다.As described above, according to the method of manufacturing the pressing piece of the nail clipper according to the present invention, the metal rod is continuously forged by the upper and lower molds, and the holes and the hinge part are formed at the triangular projection at the same time, so that the pressing piece is easy.
