Abstract

Procedimiento para curvar chapa con curvatura desde los extremos. Procedimiento para curvar chapa (C) con curvatura desde los extremos caracterizado por ser un laminado entre dos rodillos (A y B) de distinto radio (r y R). En función de la diferencia de radios, variando la distancia entre los dos rodillos se puede variar la curvatura de la chapa curvada, sin necesidad de cambiar ni fabricar utillaje adicional alguno. Si durante el proceso de curvado se va regulando la distancia entre los dos rodillos, mediante un control numérico computerizado u otro sistema, se puede obtener curvas con radio de curvatura no constante.
