Abstract

Slit materials are inserted into a die hole and a fixed shape is formed by pressing the hole up and down against a pair of punches. The materials are then inserted into a die hole, which has a bottom corner radius(R), and the die is pressed. The materials are then turned over and the process is performed again. This gives the materials a top and bottom corner radius(R). The materials are then punched in a stroke die. Finally, a rasp is formed on the surface of the materials side wall using a cold press.

본 발명은 라이타용 마찰로 어러의 제조방법에 관한 것이다. 종래 라이타용 마찰로 어러의 제조에 있어서는 강철봉을 자동선반등의 절삭기계에 의하여 절단한 소재를 주면 모서를 R지게 절삭가공하고 드릴로 취착공을 천공한후 프레스기계에 의하여 구멍형상을 정비한후 소입 경화하고 표면에 줄눈을 형성하였던것이다. 따라서 이와같은 제법에서는 소재의 절단시 바이트절삭설이 생기고 이량은 마찰로 어러의 크기와 거의 같은 량에 달하여 소재의 약 1/2이 낭비로 되며 생산비를 높이는 원인이 된다.The present invention relates to a method for producing a plurality of friction furnaces for lighters. In the conventional production of friction furnaces for writer, after cutting the steel bar by cutting machine such as automatic lathe, cutting the corner to R and drilling the drilling hole with the drill, and then repairing the hole shape by the press machine. Hardened and hardened to form joints on the surface. Therefore, in this manufacturing method, bite cutting snow occurs when cutting the material, and this amount reaches about the same amount as the size of the other by friction, which causes about half of the material to be wasted and increases the production cost.

또 절단 소재의 주면 R를 형성하기 위한 절삭작업은 숙련도를 요하며, 절삭작업은 열의 발생으로재료가 연화되므로 소입하여 마찰로 어러의 소요경도를 가지도록 하기 위하여는 보다 경도가 높은 특수강봉을 고재로, 즉 보다 고급재료를 사용할 필요가 있는 것이며, 그렇지 못할 경우 줄눈을 각설함에 있어서 줄눈 선단이 메워져 마찰력을 현저히 저하시키는 것이다. 또 절삭에 의하 주면 모서리 죽임은 예각으로 되고, 이와같이 각이진곳에 줄눈을 각설하면 첨예화되어 사용시 손가락에 상처를 일으키는 등으로 마찰로 어러의 사용성을 현저히 손상하였던 것이다. 본 발명은 이와같은 종래의 라이타용마찰로 어러의 제조기술상의 결함을 시정해결하고 일연의 프레스 공정처리에 의하여절단과 외형성형및 천공하도록 하므로서 소재의 낭비가 없고 가공과정에서의 재질의 열화를 방지함과 동시에 보다 표면의 재질을 치밀히 하고 소입성을 양호하게 하며, 가공자의 숙련도를 필요로 하지않고 높은 작업성으로 저렴한 생산원가로 제조할 수 있는 방법을 제공하는 것으로 실시에 도면에 의하여 상세히 설명한다. 철강봉을 마찰로 어러의 예정된 두께, 폭으로 소재(1)를 스릿삐로연속절단하고 다음으로 제 2도와 같은 한쌍의 펀치(2a)(2a)를 가지는 다이스(3a)의 구멍(4a)내에 소재(1)를 연속 안내장진 하여 프레스 하므로서 양단면에 요구(1a)(1a)를 형성하여 이후 가공에 적합하도록 제 3도와 같이 소재를 정형한다.In addition, the cutting work to form the main surface R of the cutting material requires skill, and the cutting work is made of special steel rods with higher hardness in order to harden the material by quenching, so that the required hardness of the roller is obtained. In other words, it is necessary to use a higher quality material, otherwise the joint tip is filled in the slitting of the joint, which significantly reduces the frictional force. In addition, the edge kill is acute when cut by cutting, and if the joint is laid out at the angled place in this manner, the usability is sharply impaired by rubbing, causing damage to the finger during use. The present invention is to correct the defects in the manufacturing technology of the conventional writer friction such as this, and to cut and external shape and perforation by a series of press processing process, there is no waste of material and prevent material deterioration during processing At the same time, it provides a method of making the surface material more dense and improving the hardenability, and can be manufactured at low production cost with high workability without requiring the skill of the worker. do. In the hole 4a of the die 3a having a pair of punches 2a and 2a as shown in FIG. 2, by continuously cutting the material 1 to the predetermined thickness and width of the roller by rubbing the steel rod. As the material 1 is continuously guided and pressed, the demands 1a and 1a are formed on both end surfaces, and the material is shaped as shown in FIG. 3 so as to be suitable for subsequent processing.

정형된 소재(1)를 제 4도와 같은 저면을 가지며 그리고 저주면에 상당한 R면(4b')를 가지는 다이스공(4b내에차례로 연속하여 안내장 진하고 펀치(2b)로 프레스처리하고 핀(5)으로 밀어올려꺼내면 제 5도와 같은 주연이 R진(1b)소재를 얻는다.The shaped material 1 has a bottom surface as shown in FIG. 4 and has a R surface 4b 'corresponding to the bottom surface thereof. When pushed up, the periphery as shown in Fig. 5 obtains the R-generating material 1b.

R진 소재는 차례로 연속적으로 제 6도와 같이 다이스(3c)의 구멍(4c)내에 뒤짚어 안내장진하고 구멍(4c)의 지면중앙에 출몰자재하게 설치한 펀치(2c)와 상부의 하부단이 가늘 게된펀치(2c)와에 의하여 소재(1)의 양면중앙에 凹부(1c)를 형성함과 동시에 다이스공(4c)의 저주면의 R면(4c')에 의하여 소재(1)의 타측면주연에 R면(1b')을 형성케하여 제 7도와 같은 소재를 얻는다.The R-shape material is sequentially guided back and forth in the hole 4c of the die 3c as shown in FIG. 6, and the punch 2c and the lower end of the upper part are thinly mounted in the center of the ground of the hole 4c. In the center of both sides of the raw material 1 by the punched punch 2c, the concave portion 1c is formed, and the other side of the raw material 1 is formed by the R surface 4c 'of the bottom surface of the die hole 4c. R surface 1b 'is formed in the peripheral edge to obtain a material as shown in FIG.

다시 제 8도와 같이 라발용 다이스(3d)의 구멍(4d)에 순처연속 안내장진하여 펀치(2d)(2d)로 凹부(1c)(1c)위치로 부터 제 9도 및 제 10도와 같이 원또는 각 형공(1d)를 천설하고 소입(당금질)을 행하여 주측면에 줄눈(1c)을 각설하므로서 전공정이 완료된다.Again, as shown in Fig. 8, the slot 4d of the Laval die 3d is continuously guided continuously, and the punches 2d and 2d are moved from the positions of the recesses 1c and 1c, as shown in Figs. 9 and 10, respectively. Alternatively, the entire process is completed by laying down each mold hole 1d and performing quenching (sugaring) to lay out the joint 1c on the main side.

이와같이 본원방법에 의한 라이타용 마찰로 어러는 작업성이 좋은 일련의 프레스공정에 의하여 제조되는 것으로 소재의 절단공정이 스릿더에 의한 절단에 의하여 행하여지므로 점단설이 전혀발생 하지않아 종래의 자동선반에 의한 바이트 절삭시 절삭설의 발생으로 재료의 1/2의 손실이 있었던 것에 비하여 재료의 현저한 절감을 기할 수 있으며, 주연을 바이트 절삭공정에 의하여 주연부가 예각으로 되는 것과는 달리 R면이 되게 형에서 프레스로서 성형되므로 사용시 손가락의 손상이 없는 것이다.In this way, the friction for the lighter according to the present method is manufactured by a series of press processes with good workability. Since the cutting process of the material is performed by cutting by the slit, no point segregation occurs and thus the conventional automatic lathe Due to the generation of cutting edges during cutting of the bite, it is possible to achieve a significant reduction of the material compared to the loss of 1/2 of the material. Since it is molded as, there is no damage to the finger when used.

이와같은 R면 형성은 凹부(1c)의 별도 구성시켜 가지고 구멍(1d)을 타발 천공하므로서 구멍(1d)의 개구 주연에도 R면이 형성되어 마찰로 어러의 취착성을 좋게하며, 또한 마찰로 어러가 일련의프레스냉간압조, 즉 강재의 냉간가공에 의하여 소재(1)의 주면부의 결정입도를 치밀히 하여 경화층(1f)을 생성시켜 경도, 인장강도 및 항복점의 현저한 상승을 기할수 있고 소입성을 좋게 하는 특징이 있는 것이다.Such R surface formation is formed separately from the concave portion 1c, and the punched hole 1d is formed so that the R surface is formed on the periphery of the opening of the hole 1d, and the frictional resistance is improved. In some cases, a series of press cold presses, that is, cold working of steel, densify the grain size of the main surface of the raw material 1 to produce a hardened layer 1f, which can significantly increase the hardness, tensile strength and yield point. There is a characteristic to make a good entrance.

또 표면경도의 증강은 줄눈(1c)형성시 눈메움이 일어나지 않으며, 종래에 소재를 바이트로 절삭가공하므로서 재질이 연화되어 특수 고급강재를 사용하여야 하였던 것과는 달리 본원방법에 의한 냉간프레스가공된 마찰로 어러는 고급강재를 사용하지 아니하고도 종래 2∼3배의 강한 내마모 특성을 가지는 제품을 비교적 저렴한 가격으로 제공하게 되는 특징이 있는 것이다.In addition, the increase in surface hardness does not cause eye filling when the joint 1c is formed, and in contrast, the material was softened by cutting the material into bite, and thus the cold press processed friction method according to the present method was required. In some cases, the present invention provides a product having a strong wear resistance of 2 to 3 times without using high quality steel at a relatively low price.
