Abstract
aparelho de corte para fazer cortes em tubos feitos de plásticos. um aparelho de corte (1) para fazer cortes em tubos de plástico compreende um disco de suporte (2) giratório em torno de um eixo geométrico de rotação (z); pelo menos uma ferramenta de corte (11) suportada pelo disco de suporte (2) por meio dos primeiros meios de suporte (12) e móvel pelo menos em direção ao eixo geométrico de rotação (z) a fim de encostar e cortar uma parede lateral (100a) do tubo (100); um disco de ajuste (3) giratório com o disco de suporte (2) e tendo em relação ao último uma respectiva posição angular ajustável em torno do eixo geométrico giratório de rotação (z), o disco de ajuste (3) sendo provido com primeiros meios móveis (15) para mover a ferramenta de corte (11) em direção ao eixo geométrico giratório de rotação (z) quando uma posição angular do disco de ajuste (3) em relação ao disco de suporte (2) é alterada; meios de acionamento (5) para girar o disco de suporte (2) e o disco de ajuste (3) em torno do eixo geométrico de rotação (z) com a mesma velocidade e compreendendo uma primeira polia de acionamento (51), girando o disco de suporte (2) por uma primeira correia (53), e uma segunda polia de acionamento (52), girando o disco de ajuste (3) por uma segunda correia (54); meios de ajuste (6) para alterar a posição angular do disco de ajuste (3) em relação ao disco de suporte (2); e que compreende um par de polias de ajuste (7) engatado pela segunda correia (54) e excentricamente fixado a um carro de ajuste móvel (8) de modo a ser móvel com o carro de ajuste (8) ao longo de uma direção de ajuste (r) para mover uma ramificação (54a) da segunda correia (54) e alterar a posição angular do disco de ajuste (3) e excentricamente girar quando movido pela segunda correia (54) e gerar um componente de oscilação no movimento de rotação do disco de ajuste (3) de modo a mover a ferramenta de corte (11) com um movimento recíproco linear quando movida pelos primeiros meios móveis (15) em direção ao eixo geométrico de rotação (z).cutting device for making cuts in tubes made of plastics. a cutting apparatus (1) for making cuts in plastic tubes comprises a support disc (2) rotatable around a geometric axis of rotation (z); at least one cutting tool (11) supported by the support disc (2) by means of the first support means (12) and movable at least towards the geometric axis of rotation (z) in order to contact and cut a side wall (100a) of the tube (100); an adjustment disc (3) rotatable with the support disc (2) and having in relation to the latter a respective adjustable angular position around the rotating geometric axis of rotation (z), the adjustment disc (3) being provided with first movable means (15) for moving the cutting tool (11) towards the rotating axis of rotation (z) when an angular position of the adjusting disc (3) relative to the support disc (2) is changed; driving means (5) for rotating the support disc (2) and the adjusting disc (3) around the geometric axis of rotation (z) with the same speed and comprising a first drive pulley (51), rotating the support disc (2) by a first belt (53), and a second drive pulley (52), rotating the adjustment disc (3) by a second belt (54); adjustment means (6) for changing the angular position of the adjustment disc (3) relative to the support disc (2); and comprising a pair of adjusting pulleys (7) engaged by the second belt (54) and eccentrically fixed to a movable adjusting carriage (8) so as to be movable with the adjusting carriage (8) along a direction of adjustment (r) to move a branch (54a) of the second belt (54) and change the angular position of the adjustment disk (3) and eccentrically rotate when moved by the second belt (54) and generate a component of oscillation in the rotational motion of the adjusting disc (3) so as to move the cutting tool (11) with a linear reciprocal movement when moved by the first movable means (15) towards the geometric axis of rotation (z).
