Abstract

The present invention relates to a mold for manufacturing a door frame. More specifically, the present invention is invented to reduce processing costs and working processes, work various shapes, manufacture a precise product, and more easily manufacture a product. To achieve the objective, the mold, according to the present invention, is manufactured such that only one mold (up, down) located on the upper side thereof is maintained as a polygon and the remaining mold is maintained at a right angle, thereby producing various shapes of door frames, reducing abrasion despite excessive use, and thus maintaining preciseness. In addition, the present invention can simplify the shape of the mold to eliminate a removal device of the door frame, reduce manufacturing costs for the mold, and raise productivity by expanding a processing range through the change of the mold shape and decreasing the number of molds and working processes.

문를프레임제작용 금형를  Door to frame making mold
【기술분야】 Technical Field
본 발명은 문를프레임을 제작하기 위한 금형를에 관한 것으로， 보다 상세하 게는 가공비용과 작업공정을 줄이고， 다양한 형상을 가공할 수 있고 정밀한 제품을 제작할 수 있도록 하였으며 제품을 보다 용이하게 제작할 수 있도록 발명한 것이 다.  The present invention relates to a mold for manufacturing a door frame, and more particularly, to reduce the processing cost and work process, to process a variety of shapes, to make a precise product and to make the product easier to invent It's done
【배경기술】 Background Art
일반적으로 문은 모든 건물에 설치하게 되고 문를은 벽체에 고정하여 문을 고정하도톡 한다 .  In general, doors are installed in all buildings, and the door is fixed to a wall to secure the door.
문를은 무거운 문을 지행해야 하므로 견고함을 유지해야 하고 오작동이 발생 할 시에 안전사고가 일어나므로 정밀한 작업을 요하게 된다.  The door should be heavy because it must carry heavy doors, and it requires precise work because safety accidents occur when malfunction occurs.
종래에는 실용신안출원번호 2으200그 0005716호가 있었으며 구체적으로 살펴 보면 금형를이 다각형의 다양한 각도로 유지하면서 형성되어 있어 작업자가 작업을 할 시에 금속재를 다양한 각도에 맞춰 삽입하고 탈거해야 하므로 작업이 번거로운 문제점이 있었으며 금형치수와 동일한 패킹치수만 가공이 가능하고 또한 형상의 가 공범위가 제한.적이었으며 문 가공시에 해밍 (He瞧 ing)작업이 불가능하였던 것으로 예를들면,  Conventionally, there was utility model application No. 2 200G 0005716. Looking specifically, the mold is formed while maintaining the polygon at various angles. Therefore, when the worker is working, the metal material must be inserted and removed at various angles. There was a problem, and only the same packing dimension as the mold dimension was possible, and the processing range of the shape was limited.Heaming was not possible during the door processing.
꺽임부가 있는 판재의 사이에 또 다른 관재가 삽입되어 있는 과 같은 형상의 제작은 불가능하여 또 다른 프레스 공작기기를 통하여 제작하였던 것 이다. It was not possible to produce the same shape as another pipe inserted between the plate with the bending part, and it was produced through another press machine tool.
금형의 구조가 복잡하여 별도의 문를 탈거장치를 부착해야 하므로 작업공정 수가 늘어나게 되고 이에 따라 제작비가 상승되는 문제점이 있었던 것이다.  Since the structure of the mold is complicated, a separate door must be attached to the removal device, thereby increasing the number of working processes and increasing manufacturing costs.
또한 장시간 사용시 금형를의 마모율이 커서 금속재가 금형를에 맞지가 않아 금형를을 자주 다시 제작해야 하는 분제점이 있었던 것이다. 【발명의 상세한 설명】 In addition, since the wear rate of the mold is too long to use for a long time, there was a powder point where the metal was not refitted to the mold and the mold was to be rebuilt frequently. [Detailed Description of the Invention]
