Title (EN) MOLDING DEVICE
(FR) DISPOSITIF DE MOULAGE
(JA) 成形装置
Abstract:
(EN) This molding device for molding a metal pipe by expanding a metal pipe material is provided with: a mold which includes upper and lower molds for molding the metal pipe, of which at least one is moveable; electrodes for heating the metal pipe material by energizing the metal pipe material; a gas supply unit which supplies gas to the inside of the heated metal pipe material to expand the metal pipe; and a mold motion suppression unit which suppresses movement of the mold due to electromagnetic forces, at least during the energization of the metal pipe material by means of the electrodes.
(FR) L'invention concerne un dispositif de moulage permettant de mouler un tuyau métallique par l'expansion d'un matériau de tuyau métallique comprenant: un moule qui comprend des moules supérieur et inférieur pour mouler le tuyau métallique, au moins l'un d'entre eux étant mobile; des électrodes permettant de chauffer le matériau de tuyau métallique par excitation du matériau de tuyau métallique; une unité d'alimentation en gaz qui fournit du gaz à l'intérieur du matériau de tuyau métallique chauffé pour dilater le tuyau métallique; et une unité de suppression de mouvement de moule qui supprime le mouvement du moule en raison de forces électromagnétiques, au moins pendant l'excitation du matériau de tuyau métallique au moyen des électrodes.
(JA) 金属パイプ材料を膨張させて金属パイプを成形する成形装置であって、少なくとも一方が移動可能であり、金属パイプを成形する上型及び下型を有する金型と、金属パイプ材料へ通電することで当該金属パイプ材料を加熱する電極と、加熱された金属パイプ材料内に気体を供給して膨張させる気体供給部と、少なくとも電極による金属パイプ材料への通電時に、電磁力による金型の移動を抑制する金型移動抑制部と、を備える、成形装置。
