Abstract: front page image
(EN)A method for producing a centrifugal fan according to the present invention comprises the steps of: (a) forming static pressure surface members and a negative pressure surface members for static pressure surfaces and negative pressure surfaces, respectively, by cutting a metal plate; (b) creating first curved sections for the static pressure surfaces and second curved sections for the negative pressure surfaces by applying pressure to static pressure surface members and negative pressure surface members; (c) trimming the static pressure surface members and a negative pressure surface members on which first and second curved sections, respectively, are formed to form shroud connection sections and main plate connection sections; (d) bending the shroud connection sections and main plate connection sections; (e) joining the static pressure members and the negative pressure members; and, (f) with the static pressure members and the negative pressure members joined, joining the shroud connection sections and main plate connection sections, and joining the main plate connection sections and the main plate.
(FR)Un procédé de production d'un ventilateur centrifuge selon la présente invention comprend les étapes suivantes : (a) former des éléments à surface de pression statique et des éléments à surface de pression négative pour des surfaces de pression statique et des surfaces de pression négative, respectivement, par découpe d'une plaque de métal; (b) créer de premières sections courbes pour les surfaces de pression statique et de secondes sections courbes pour les surfaces de pression négative, par application de pression à des éléments à surface de pression statique et à des éléments à surface de pression négative; (c) ébavurer les éléments à surface de pression statique et les éléments à surface de pression négative sur chacun desquels sont formées respectivement les première et seconde sections courbes, de manière à former des sections de connexion renforcées et des sections de connexion de plaque principale; (d) cintrer les sections de connexion renforcées et les sections de connexion de plaque principale; (e) assembler les éléments de pression statique et les éléments de pression négative; et, (f) assembler, au moyen des éléments de pression statique et des éléments de pression négative, les sections de connexion renforcées et les sections de connexion de plaque principale, et assembler les sections de connexion de la plaque principale et la plaque principale.
(KO)본 발명의 원심팬의 제조방법은 (a) 금속판재를 재단하여 정압면과 부압면을 각각 구성하는 정압면 형성부재 및 부압면 형성부재를 형성하는 단계; (b) 상기 정압면 형성부재와 부압면 형성부재를 각각 가압하여 상기 정압면을 구성하는 제 1 곡면부와, 상기 부압면을 구성하는 제 2 곡면부를 형성하는 단계; (c) 상기 제 1 곡면부가 형성된 정압면 형성부재와 상기 제 2 곡면부가 형성된 부압면 형성부재를 트리밍하여 쉬라우드 접합면부 및 주판 접합면부를 형성하는 단계; (d) 상기 쉬라우드 접합면부와 상기 주판 접합면부를 밴딩시키는 단계; (e) 상기 정압면 형성부재와 부압면 형성부재를 서로 접합하는 단계; 및 (f) 상기 정압면 형성부재와 부압면 형성부재가 접합된 상태에서, 상기 쉬라우드 접합면부와 상기 쉬라우드를 접합하고, 상기 주판 접합면부와 상기 주판을 접합하는 단계를 포함한다.
