Abstract
(EN)
Disclosed are a local heat treatment system and a cold forming method using same. According to one aspect of the present invention, a local heat treatment system may be provided, the system comprising: a heating device for locally heating only a plastically deformed section of a blank material to a certain temperature; a moving device for moving the heating device to the position of a local heating area of the blank material; and a control device for controlling the heating device and the moving device.
(FR)
L'invention concerne un système de traitement thermique local et un procédé de formation de froid utilisant celui-ci. Selon un aspect de la présente invention, un système de traitement thermique local peut être fourni, le système comprenant : un dispositif de chauffage pour chauffer localement uniquement une section plastiquement déformée d'un matériau vierge jusqu'à une certaine température ; un dispositif de déplacement pour déplacer le dispositif de chauffage vers la position d'une zone de chauffage local du matériau vierge ; et un dispositif de commande pour commander le dispositif de chauffage et le dispositif de déplacement.
(KO)
국부 열처리 시스템 및 이를 이용한 냉간 성형 방법이 개시된다. 본 발명의 일 측면에 따르면, 블랭크 소재의 소성변형 발생 부위만 국부적으로 일정온도로 가열하는 가열장치; 상기 가열장치를 상기 블랭크 소재의 국부가열영역 위치까지 이동시키는 이동장치; 및 상기 가열장치 및 이동장치를 제어하는 제어장치;를 포함하는 국부 열처리 시스템을 제공할 수 있다.
