Abstract
"MéTODO DE FORMAR UM COPO DE METAL LAMINADO SEM UM MANDRIL". A invenção compreende um método de formar um copo de metal laminado sem usar um mandril. Um copo em formato de copo é primeiro produzido tendo um relevo em uma circunferência externa de aro. O molde é preso na máquina de rotação. O relevo controla e facilita o processo de curvatura, criando uma curva uniforme em um ponto de curvatura predeterminado. Durante o processo de rolamento, um cilindro de formação é engatado com o aro, e é movido progressivamente paralelo com um eixo de rotação. Quando o cilindro de formação se move, o aro é curvado progressivamente de uma orientação normal a um eixo de rotação para uma posição paralela ao eixo de rotação. O aro completamente formado pode então ser perfurado, se necessário, para acomodar um mancal ou haste. Isto permite que um copo de raio pequeno, que pode então ser usado como uma polia ou polia louca, seja formado sem o uso de um mandril.
