Abstract

L'invenzione concerne una pressa piegatrice per tubi con grande lunghezza di flessione del tipo costruttivo a telaio chiuso, il cui telaio è costituito da montanti laterali come pure da una traversa superiore e da una inferiore, la tavola, portante gli utensili piegatori inferiori, essendo sostenuta sulla traversa inferiore e l'utensile piegatore superiore, guidato verticalmente, parallelamente sui montanti laterali, essendo sostenuto in modo sollevabile e abbassabile attraverso più gruppi a cilindro/pistone identici, disposti l'uno accanto all'altro, contro la traversa superiore, le camere cilindriche di gruppi a cilindro/pistone essendo collegate attraverso un condotto di comando comune con un gruppo comune di un fluido sotto pressione. Per impedire con mezzi relativamente semplici la inflessione degli utensili piegatori in modo che possa essere realizzato un tubo conforme alle misure e qualitativamente perfetto, viene proposto che fra la tavola (10), portante gli utensili piegatori inferiori (9) e la traversa inferiore (5) sono disposti gruppi a cilindro/pistone inferiori (8).
