Abstract
Procedimiento para fabricar poleas de varias acanaladuras para correas trapezoidales, a partir de chapa, por conformación en frío de una pieza en bruto en forma de bote, previamente producida, con ayuda de partes de molde con forma de segmentos, desplazables axialmente, las cuales forman anillos de molde, que rodean a la pieza en bruto, caracterizado porque las partes de molde son aproximadas en sentido radial a la pieza en bruto en una distancia axial exactísimamente ajustada entre ellas, porque un cuerpo de soporte es movido a través de las partes de molde de al menos uno de los anillos de molde, de modo tal que, las partes de molde no pueden moverse radialmente hacia fuera durante el proceso de conformación, porque la pieza en bruto es llenada con líquido y la presión en el líquido es controlada en este cado de modo tal que las paredes de la pieza en bruto se apoyan firmemente en las partes de molde a lo largo de líneas periféricas que se encuentran a distancia entre si, porque luego lapieza en bruto con forma de bote es comprimida conjuntamente en dirección axial, moviéndose las partes de molde movibles, que forman los anillos de molde, simultáneamente así como independientemente entre sí en dirección axial desde una posición inicial al comienzo del proceso de conformación hasta una posición final al final del proceso de conformación, sin que ellas estén sometidas a una presión dirigida axialmente desde ninguna otra parte del dispositivo , y porque luego es alejado el cuerpo de soporte , que rodea a las partes de molde y porque después de ello las partes de molde son alejadas radialmente hacia fuera desde la polea terminada para correas trapezoidales.
