Abstract

INSTALAÇÃO DE RISCAR A LASER PARA O TRATAMENTO SUPERFICIAL DE CHAPAS MAGNÉTICAS COM PONTOS DE SEÇÃO ELÍPTICA. A presente invenção refere-se a uma instalação de riscar a laser (22) para o tratamento de chapas magnéticas com grãos orientados como uma tira (26) em movimento longitudinal, que compreende um gerador de laser para um feixe de laser (46a, 46b), um grupo óptico telescópico cilíndrico (38a, 38b) com distância focal variada para a formação de um feixe de laser com seção elíptica (49a, 49b) apresentando elipticidade variada como função das distâncias focais e um scanner de espelho rotativo (39a, 39b) para varrer o feixe de laser de acordo com um ângulo predefinido. A instalação de riscar (22) adicionalmente compreende um refletor parabólico (54) estendido transversalmente à tira (26), para receber o feixe de laser varrido (51a, 51b) e focalizar o feixe sobre a tira (26), como um ponto elíptico grandemente encompridado (55), ao longo de um percurso de tratamento (53a, 53b), e no qual o grupo telescópico (38a, 38b) é ajustável para modificar o comprimento de um dos eixos na seção elíptica do feixe de laser (52a, 52b) incidente sobre a tira (26).
