본 고안은 착정용(鑿井用 ) 함마 케이스에 관한 것이다.The present invention relates to a hammering case for landing.

종래의 사용되어온 착정용 함마는 수입품으로 함마 케이스를 형성함에 있어서 주면으로 다수의 공기통공을 형성한 양단부에 내측으로 나사를 형성시켜 장고형으로 형성된 슬리브의 외측에 4쪽으로 분할한 철판을 양쪽 플랜지의 내단부에 용접함과 동시에 분할단면을 길이 방향으로 용접하여 카버를 형성하므로서 슬리브의 외주면과 카버의 내주면사이에 공기통로가 형성되게 케이스를 구성하였으므로 제작할때 용접과 열처리의 문제로 인하여 사용시 연속적인 충격으로 인한 용업부위 박리현상이 일어나게 되어 공기의 누출로 인한 함마의 작동이 불능하게 되었고, 카버를 용접에 의하여 부착할때 고열로 슬리브가 변형되어 필요한 정밀도를 유지할 수 없게 되므로서 제품의 품질을 저하시켰으며 제작이 번거로워 제품가를 상승시키게 되는 등의 결점이 있었다.Conventionally used hammer for the hammer is to import the hammer case in the form of a plurality of air holes in the inner surface to form a screw case inward to form a screw inwardly divided into four sides on the outer side of the sleeve formed in the form of both sides of both flanges The casing is formed between the outer circumferential surface of the sleeve and the inner circumferential surface of the carver by welding the split section in the longitudinal direction at the same time as welding on the inner end. Due to the separation of the industrial parts, the hammer was not able to operate due to air leakage, and the sleeve was deformed due to high heat when welding the carver by welding, thereby degrading the quality of the product. It is cumbersome to make the product price higher. There was.

본 고안은 이와같은 종래의 결점을 시정하기 위하여 안출한 것으로서 케이스를 3개로 분할하여 형성하고 양단부 내측으로 나사를 형성하여 일단부 나사의 내측으로 근접하여 단턱을 형성한 것에 원주면으로 공지의 공기통공을 다수 형성한 일단부에는 플랜지를 형성한 슬리브를 끼우고 일단부에는 내측으로 나사를, 타단부에는 외측으로 나사를 형성한 플랜지를 끼우면 슬리브의 외주면과 카버의 내주면 사이에 공지의 공기통로가 형성되므로 특수 접착제로 조립하여 카버의 내단부와 플랜지의 내단부를 서로 용접하여 케이스를 구성하였으므로 가공공정이 간편하여 양질의 제품을 양산할 수 있고 제품원가를 1/3정도 절감할 수 있으며 내부(라이너)의 열처리 문제가 용이할 뿐 아니라 정밀가공을 기할 수 있음은 물론 제품의 정밀도를 높일 수 있는 효과를 가진 실용적인 고안으로서, 이를 첨부된 도면에 의하여 그 구조 및 작용효과를 상세히 설명하면 다음과 같다.The present invention devised to correct such a conventional drawback, is formed by dividing the case into three and forming a screw inside both ends to form a step in close proximity to the inside of the screw at one end is known as a circumferential surface air vent One end formed with a plurality of flanges is fitted with a sleeve formed with a flange, one end is screwed into the inside, and the other end is fitted with a flange formed with a screw outward, a known air passage is formed between the outer peripheral surface of the sleeve and the inner peripheral surface of the cover Since it is assembled with a special adhesive and welded the inner end of the cover and the inner end of the flange together to form a case, the processing process is simple, it can mass-produce high-quality products, reduce the product cost by 1/3, and internal (liner) Not only makes the heat treatment problem easy, but also enables precision processing and increases the accuracy of the product. As a practical design with a description, it will be described in detail the structure and effect by the accompanying drawings as follows.

양단부의 내측으로 나사(2)(2')를 형성하여 일단부의 나사(2) 내측으로 근접한 부위에 단턱(3)을 형성한 카버(1)의 내측으로 원주면에 공지의 공기통공(5)을 다수 형성하고 일단 외측으로 플랜지(6)를 형성한 슬리브(4)를 끼운 다음, 외단 내측으로 나사(8)를 형성한 플랜지(7)의 내단 외측의 나사(8')를 카버(1)의 나사(2')에 나착하면 슬리브(4)의 외주면과 카버(1)의 내주면사이에 공지의 공기통로(9)가 형성되게 요입부를 용접하여 케이스(C)를 구성함을 특징으로 한 것이다.Known air holes (5) on the circumferential surface of the cover (1) forming the screw (2) (2 ') inside the both ends and forming the step (3) in the portion adjacent to the inside of the screw (2) of one end And insert the sleeve 4 having the flange 6 formed on the outer side once, and then attach the screw 8 'of the inner end outer side of the flange 7 on which the screw 8 is formed inside the outer end. Is attached to the screw (2 ') of the sleeve 4 and the inner circumferential surface of the carver (1) to the well-known air passage (9) is formed so as to form a case (C) by welding .

이와같이 구성된 본 고안은 통상의 착정용 함마의 케이스(C)로 사용케 되는 것으로서 그 작용효과를 상세히 설명하면 본 고안과 같이 케이스(C)를 3개로 분할하여 조립으로 구성하므로서 용접 및 열처리로 인한 문제점을 해소하게 되어 사용시 연속적인 충격으로 인한 공기누출을 방지하고 제품의 정밀도를 유지할 수 있어 제품의 품질을 높을 수 있음은 물론 제품의 원가를 최대한 낮출 수 있고 정밀가공을 기할 수 있으며 내부(라이너)의 열처리가 용이하고 가공이 간편하여 양질의 제품을 양산할 수 있는 이점을 가진 실용적인 유용한 고안이다.The present invention configured as described above is to be used as a case (C) of a normal landing hammer, and the effect thereof is described in detail, and thus, the problem caused by welding and heat treatment is achieved by dividing the case (C) into three as in the present invention. It can solve the problem of air leakage due to continuous impact and maintain the precision of the product, so that the quality of the product can be improved, the cost of the product can be reduced as much as possible, and the precision processing can be performed. It is a practical and useful design with the advantage of mass production of high quality products with easy heat treatment and easy processing.
