Abstract: front page image
(EN)The present invention relates to an ultra-high-speed molding method and, more specifically, to "an ultra-high-speed molding method using an electroplasticity effect", the method enabling a predetermined pulse current to be applied to a molding material to be processed so as to instantly lower the stress of the molding material to be processed, and then enabling a predetermined force to be applied, at an ultrahigh speed, to the molding material to be processed so as to mold the molding material to be processed. The ultra-high-speed molding method using an electroplasticity effect, according to the present invention, comprises the steps of: (a) performing electroplasticity on a molding material to be processed; and (b) molding the molding material to be processed by providing, at an ultrahigh speed, a predetermined molding force to the molding material to be processed. The present invention has an advantage of molding, at an ultrahigh speed (molding time: 150-300 ㎲), a molding material to be processed. In addition, the present invention applies a predetermined molding force to a molding material to be processed, in synchronization with the deterioration of the stress of the molding material to be processed, thereby having an advantage of comparatively saving more energy consumed for the molding force.
(FR)La présente invention concerne un procédé de moulage à ultra-haute-vitesse et, plus spécifiquement, "un procédé de moulage à ultra-haute-vitesse utilisant un effet d'électroplasticité", le procédé permettant l'application d'un courant d'impulsion prédéterminé sur un matériau de moulage à traiter pour réduire instantanément la contrainte du matériau de moulage à traiter, et permettre ensuite l'application d'une force prédéterminée, à ultra-haute vitesse, sur le matériau de moulage à traiter de façon à mouler le matériau de moulage à traiter. Le procédé de moulage à ultra-haute vitesse utilisant un effet d'électroplasticité, selon la présente invention, comprend les étapes consistant à : (a) réaliser l'électroplasticité sur un matériau de moulage à traiter; et (b) mouler le matériau de moulage à traiter en générant, à ultra-haute vitesse, une force de moulage prédéterminée sur le matériau de moulage à traiter. La présente invention présente l'avantage de mouler, à ultra-haute vitesse (temps de moulage : 150 à 300 ㎲), un matériau de moulage à traiter. En outre, la présente invention applique une force de moulage prédéterminée sur un matériau de moulage à traiter, en synchronisation avec la détérioration de la contrainte du matériau de moulage à traiter, ce qui a pour avantage d'économiser comparativement plus d'énergie consommée pour la force de moulage.
(KO)본 발명은 초고속 성형 방법에 관한 것으로, 보다 구체적으로는 피가공 성형재에 소정의 펄스 전류를 인가하여 피가공 성형재의 응력을 순간적으로 떨어뜨린 후 피가공 성형재에 초고속으로 소정의 힘을 인가하여 피가공 성형재를 성형하기 위한 "전기소성효과를 이용한 초고속 성형 방법"에 관한 것이다. 본 발명에 따른 전기소성효과를 이용한 초고속 성형 방법은 (a) 피가공 성형재에 대하여 전기소성을 수행하는 단계; (b) 상기 피가공 성형재에 대하여 소정의 성형력을 초고속으로 제공하여 상기 피가공 성형재를 성형하는 단계로 이루어지는 것을 특징으로 한다. 이러한 본 발명은 피가공 성형재를 초고속(성형시간: 150~300㎲)으로 성형할 수 있다는 이점이 있다. 또한 본 발명은 피가공 성형재의 응력이 저하되는 시점에 동기되어 소정의 성형력을 피가공 성형재에 인가하므로 그렇지 않은 경우보다 성형력에 소비되는 에너지를 절감할 수 있다는 이점이 있다.
