Abstract

1396751 Curving by rolls VERRINA SpA 28 Sept 1972 [1 Oct 1971] 44861/72 Heading B3E A roll bending machine comprises an upper roll and at least two adjustable lower rolls journalled at their ends in supports on a frame, one journal support of the upper roll being pivotable relative to the frame while the other is disengageably secured thereto, one of the rolls being driven by a motor/reduction gear assembly secured to a journal support. In the figure, sheet metal is curved into tubular form surrounding the upper roll 1 which is pivotable to enable the tube to be removed. The middle roll 3 of three lower rolls is shown. Journal 101 of roll 1 is received in journal box 5 attached to a frame 6 pivoted at 7 to a fixed frame 8. Journal 201 of roll 1 is received in journal box 9 engaged by pins 30 in a frame 10 pivoted to the fixed frame at 111. An hydraulic or electric motor 24 and reduction gear 25 are secured to frame 6 and coupled to drive roll 1. The pivoted frames 6, 9 are connected by linkwork including lost motion device 18, 19 to an hydraulic cylinder 16, so that after formation of a tube, pin 30 can be withdrawn and cylinder 16 actuated to free journal box 9 and pivot the roll and motor/ reduction gear assembly about pivot 7. The lower rolls are vertically adjustable by hydraulic rams 123. In another embodiment, Fig. 4 (not shown), the motor reduction unit is secured to the journal box of a driven lower roll.
