Description
본 발명은 철도차량용 구체의 경량화, 조립성의 강화, 제작기간의 단축, 제조원가의 절감을 도모할 수 있게 한 철도차량용 구체의 제조방법에 관한 것이다.The present invention relates to a method for manufacturing a sphere for a railway vehicle, which makes it possible to reduce the weight of a sphere for a railway vehicle, enhance assembly properties, shorten the production period, and reduce manufacturing costs.
철도차량용 구체는 그 차량을 구성하는 여러 부품 가운데서도 질량비율이 가장 크기 때문에 철도차량의 경량화라는 과제를 선정함에 있어서는 언제나 우선 검토대상이 돼 왔다. 기존의 철도차량용 구체는 도 1에 예시한 바와 같이 스테인레스강재나 알루미늄재로 골조를 형성한 후 스테인레스강재나 알루미늄재 표면재를 용접하는 방식으로 제작해 왔다. 그러나 이 방법으로 제작된 철도차량용 구체는 매번 용접해야 하는 번거로움과 복잡한 조립공정, 차체의 중량증가, 및 막중한 중량감으로 인한 레일수명의 단축 등 여러 가지 문제점을 내포하고 있다.Since the sphere for railroad cars has the largest mass ratio among the components that make up the vehicle, it has always been the first consideration when selecting the task of reducing the weight of railroad cars. Existing railway vehicle sphere has been produced by welding a stainless steel or aluminum surface material after forming a frame made of stainless steel or aluminum as shown in FIG. However, the spherical sphere for railroad cars manufactured by this method has various problems such as the troublesome welding process every time, complicated assembly process, increase of the weight of the body, and reduction of the rail life due to the heavy weight.
따라서, 철도차량용 구체를 조립식으로 제작하는 기술과 관련하여 장래의 과제는 경량화, 조립공수의 단축, 경제성, 및 품질향상에 주력해야 할 것으로 생각된다.Therefore, it is considered that future tasks related to the technology of manufacturing a sphere for railroad cars in a prefabricated manner should focus on weight reduction, shortening of assembly labor, economy, and quality improvement.
본 발명은 이러한 기대에 부응키 위한 것으로, 구체의 경량화를 구현하기 위하여 폴리우레탄, 폴리에틸렌, 폴리메트아크릴아미드 등의 발포수지판 양면에 유리섬유를 덧대어 스티칭한 스티칭판의 양면에 알루미늄판을 접합한 복합판재를 지붕 패널과 측면 패널 및 바닥 패널로 하고, 이들 각 패널의 양끝에 알루미늄 압출물을 삽입하여 일체로 성형한다. 상기 스티칭 구조물은 알루미늄 하니컴 구조물로 대체해도 동등한 실시효과를 거둘 수 있다.The present invention is to meet these expectations, in order to realize the weight reduction of the sphere, bonding the aluminum plate on both sides of the stitching plate stitched with glass fiber on both sides of the foamed resin plate such as polyurethane, polyethylene, polymethacrylamide, etc. One composite plate is a roof panel, a side panel, and a bottom panel, and an aluminum extrudate is inserted into both ends of each panel to be integrally formed. The stitching structure may have an equivalent performance effect even by replacing the aluminum honeycomb structure.
상기 지붕 패널과 측면 패널은 알루미늄압출물 보강프레임을 조립매개체로 하여 각 패널과 보강프레임의 단부를 맞대어 용접하고, 바닥 패널과 측면 패널은 알루미늄 압출물제 코너프레임을 조립매개체로 하여 각 패널의 단부와 코너프레임의 단부를 용접하는 아주 간단한 방법으로 철도차량용 구체를 제조하는 것이다.The roof panel and the side panel are welded to each end of the panel and the end of the reinforcing frame by using the aluminum extrusion reinforcement frame as an assembly medium, the bottom panel and the side panel is a corner frame made of aluminum extrusion as an assembly medium, A very simple way to weld the end of a corner frame is to manufacture a sphere for a railway vehicle.

이하, 본 발명을 바람직한 실시예에 의거 작성한 제2도 이하의 첨부도면에 따라 구체적으 로 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings of FIG. 2 according to a preferred embodiment.
도 2 내지 도 4에서, 본 발명의 철도차량용 구체는, 저면에 천정판(4)이 부착된 지붕 패널(1)과 출입구(7)와 창구(8) 등이 형성된 좌,우 측면 패널(2)과는 알루미늄 압출물제 보강프레임(5)을 조립매개체삼아 용접하고, 측면 패널(2)과 바닥 패널(3)도 상기 보강프레임(5)과는 형상은 비록 다르지만 이 또한 알루미늄 압출물제 코너프레임(6)을 이용하여 조립한다.2 to 4, the sphere for the railway vehicle of the present invention, the roof panel 1 with the ceiling plate 4 attached to the bottom, the left and right side panels (2) formed with the entrance 7 and the window 8, etc. ) And the reinforcing frame (5) made of aluminum extrudate as a welding medium, and the side panel (2) and the bottom panel (3) is also different from the reinforcing frame (5), although the shape of the corner frame made of aluminum extrusion ( 6) to assemble.
상기 지붕 패널(1)과 측면 패널(2) 및 바닥 패널(3)은 다같이 폴리우레탄, 폴리에틸렌, 폴리메트 아크릴아미드 등의 발포수지제로써, 위치별로 각기 그 용도의 형상에 맞게 제작한 발포수지판의 양면에 유리섬유를 덧대고 스티칭한 스티칭물의 양면에 알루미늄판을 접합하여 패널화한 것으로, 종래의 철제 패널에 비해 훨씬 가볍고, 각기 독립된 표면재·내장재·단열재·프레임이 필요했던 종래와는 달리 발포수지제 스티칭물은 그 자체가 프레임과 단열재 및 내장재의 역할을 겸하므로 제조공정이 대폭 단축되고, 제조원가도 훨씬 저렴해진다.The roof panel 1, the side panel 2, and the bottom panel 3 are all made of foamed resin such as polyurethane, polyethylene, polymethacrylamide, and the like. It is a panel made by joining aluminum plates on both sides of a plate with glass fiber and stitching on it, which is much lighter than conventional steel panels, and is foamed unlike the conventional case where independent surface materials, interior materials, insulation materials, and frames were required. Since the resin stitching itself serves as a frame, a heat insulator and an interior material, the manufacturing process is greatly shortened and the manufacturing cost is much cheaper.
이와는 달리 지붕 패널(1)과 측면 패널(2) 그리고 바닥 패널(3)을 알루미늄 하니컴 구조물로 대용할 수도 있다. 이렇게 알루미늄 하니컴 구조물로 대체하면 내하중이 더욱 증대된다.Alternatively, the roof panel 1, the side panel 2 and the floor panel 3 may be substituted with an aluminum honeycomb structure. If the aluminum honeycomb structure is replaced in this way, the load capacity is further increased.
도 3에서, 지붕 패널(1)과 측면 패널(2)의 조립에 쓰이는 보강프레임(5)은 위 아래로 지붕 패널(1)과 측면 패널(2)이 일체로 형성된 알루미늄 압출재 부분에 각각 맞물려서 용접하기 쉬운 구조를 갖추고, 그 내면의 하반부상에는 천정판(4)의 양측 단부를 끼워 걸어서 안정시키기 위한 홈(9)도 형성한다. 지붕 패널(1)과 천정판(4) 사이에는 냉/온방용 덕트, 조명장치, 방송시설 등이 위치하게 된다.In Fig. 3, the reinforcement frame 5 used for assembling the roof panel 1 and the side panel 2 is welded by engaging the aluminum extruded material portions in which the roof panel 1 and the side panel 2 are integrally formed up and down, respectively. It has a structure which is easy to do, and the groove | channel 9 for stabilizing by engaging both ends of the ceiling board 4 on the lower half part of the inner surface is also formed. Between the roof panel 1 and the ceiling plate 4, air / heating ducts, lighting devices, broadcasting facilities, and the like are located.
도 4에서, 측면 패널(2)과 바닥 패널(3)의 조립에 쓰이는 코너프레임(6)은 L형이며, 상기 보강프레임(5)과 마찬가지로 수직부는 측면 패널(2)의 알루미늄 압출재에 그리고 수평부는 바닥 패널(3)의 알루미늄 압출물인 접속재(10)와 각기 서로 맞물려서 용접하기 좋은 구조로 형성한다.In FIG. 4, the corner frame 6 used for the assembly of the side panel 2 and the bottom panel 3 is L-shaped, and similarly to the reinforcement frame 5, the vertical part is in the aluminum extruded material of the side panel 2 and horizontally. The parts are formed in a structure that is easy to weld to each other by engaging with the connecting member 10, which is an extruded aluminum of the bottom panel 3, respectively.
도 5에서, 지붕 패널(1)과 보강프레임(5), 측면 패널(2)과 보강프레임(5) 및 코너프레임(6), 바닥 패널(3)과 코너프레임(5)간의 접속에 있어서는 알루미늄 압출물인 접속재(10)를 사용하여 접속과 동시에 접합한다.In Fig. 5, aluminum is used for the connection between the roof panel 1 and the reinforcement frame 5, the side panel 2 and the reinforcement frame 5 and the corner frame 6, the bottom panel 3 and the corner frame 5, respectively. It joins simultaneously with connection using the connection material 10 which is an extrusion product.
도 6에서, 지붕 패널(1)과 측면 패널(2) 및 바닥 패널(3)은 폴리우레탄, 폴리에틸렌, 폴리메트아크릴아미드 등으로 된 발포수지판(9)의 양면에 유리섬유(11)를 적층하여 스티칭하고, 이 스티칭물의 양면에 알루미늄판(12)을 접합한 것이다.In FIG. 6, the roof panel 1, the side panel 2, and the bottom panel 3 laminate the glass fibers 11 on both sides of the foamed resin plate 9 made of polyurethane, polyethylene, polymethacrylamide, or the like. And stitching, and the aluminum plate 12 is bonded to both surfaces of this stitching material.
조립한 다음의 순서에 따른다. 도 4에서, 우선은 바닥 패널(3)의 양 끝에 위치한 알루미늄 압출재와 코너프레임(6)을 맞추고 용접한다. 이어서 상기 코너프레임(7)의 수직부에 측면 패널(2)의 저면 알루미늄 압출재를 맞춰 용접하고, 각 각의 측면 패널(2)의 상변에는 보강프레임(5)을 얹어서 용접한다.Follow the procedure assembling. In Fig. 4, first of all, the corner frame 6 is welded and welded with aluminum extruded material located at both ends of the bottom panel 3. Subsequently, the bottom aluminum extruded material of the side panel 2 is matched and welded to the vertical portion of the corner frame 7, and the reinforcement frame 5 is welded on the upper side of each side panel 2.
한편, 지붕 패널(1)의 저면으로 천정판(4)을 올려붙이고, 지붕 패널(1)을 상기 보강프레임(5) 위에 앉힌다. 이때, 천정판(4)의 양쪽 가장자리는 보강프레임(5)의 홈에 맞춰 끼운 다음에 지붕 패널(1)과 보강프레임(5)에 용접한다. 이리하여 도 2와 같은 형태의 철도차량용 구가 완성되는 것이다.On the other hand, the ceiling plate 4 is attached to the bottom of the roof panel 1, and the roof panel 1 is seated on the reinforcing frame 5 above. At this time, both edges of the ceiling plate 4 is fitted to the groove of the reinforcement frame 5 and then welded to the roof panel 1 and the reinforcement frame 5. This completes the railroad vehicle sphere of FIG. 2.
이상 설명한 바와 같이 본 발명은 폴리우레탄, 폴리에틸렌, 폴리메트아크릴아미드 등으로 된 발포수지판(9)의 양면에 유리섬유(11)를 덧대어 스티칭한 스티칭물의 양면에 알루미늄판(12)을 접합한 것을 지붕 패널(1)과 측면 패널(2) 및 바닥 패널(3)로 하고(알루미늄 하니컴 구조물로 대체할 수도 있다), 지붕 패널(1)과 측면 패널(2)은 알루미늄제 보강프레임(5)을 조립매개체삼아 조립 용접하며, 바닥 패널(3)과 측면 패널(2)은 알루미늄제 코너프레임(6)을 조립매개체삼아 조립 용접하여 철도차량용 구체를 제작하는 것으로, 구체의 소재 자체가 경량질인데다 형태의 안정 및 유지를 위한 별도의 철골조를 요하지 않으므로 종전의 철제 구체에 비해 대단히 가벼우면서도 튼튼하고, 표면재와 내장재, 단열재를 별도로 사용할 필요가 없으므로 공정수도 현저히 줄고, 대당 제작비도 대폭 절감된다.As described above, according to the present invention, the aluminum plate 12 is bonded to both sides of the stitched material by stitching the glass fiber 11 on both sides of the foamed resin plate 9 made of polyurethane, polyethylene, polymethacrylamide, or the like. The roof panel 1 and the side panel 2 and the bottom panel 3 (although it may be replaced by an aluminum honeycomb structure), and the roof panel 1 and the side panel 2 are made of aluminum reinforcement frame 5. Assembly and welding by using as an assembly medium, and the bottom panel (3) and the side panel (2) fabricate the aluminum sphere frame (6) as an assembly medium to fabricate a sphere for railroad cars, the material of the sphere itself is lightweight. It does not require a separate steel frame for the stability and maintenance of the form, so it is much lighter and more robust than the previous steel spheres, and the number of processes is also significantly reduced since there is no need to use surface materials, interior materials and insulation materials separately. It is also significantly reduce per unit production costs.
또, 구체의 구성요소인 지붕 패널(1)과 측면 패널(2) 및 바닥 패널(3)로 구분 제작하여 유닛화하고 보강프레임(5)과 코너프레임(6)을 조립매개체삼아 유기적으로 조립 용접하는 순전히 평면작업에 의하므로 조립공수는 더욱 줄고 제작성은 개선되며, 대당 제작소요시간도 대폭 단축된다.In addition, the roof panel 1, the side panel 2, and the floor panel 3, which are components of the sphere, are manufactured and united, and the reinforcement frame 5 and the corner frame 6 are assembled and organically welded using the assembly medium. Because of the purely flat work, the assembly labor is reduced, the productivity is improved, and the manufacturing time per unit is greatly reduced.
