ABSTRACT:
A roller machine for profile cold bending includes a bearing framework with mounted supports, carrying power driven shape forming calibers. The bearing framework is composed of at least two module components at the adjacent ends of which are mounted supports, connected between them with crosswise to the machine's axis horizontal bars with which, by means of end carriers, are joined two interparallel blocks of bars, each of which comprises lengthwise bars, connected through vertical bearers, at one side of which, pertaining to each one of the bar blocks, are mounted freely rotating horizontal, cylindrical and shape forming rollers, secured at a fixed angle per each transition, while at the other side of the vertical bearers are mounted on guides axially movable free rotating cylindrical rollers, but over at least one of the module components, in crosswise position to the machine's axis, are mounted a top and a bottom axially movable shape forming blocks, fastened by a clamping device to a top and a bottom horizontal rollers respectively, while the top and bottom shape forming blocks are fixed in operating position by way of fixing couplings.
