The object of the present invention, a multi-function combined press-bending-calendering machine with one or two flaps, folding and bending sheet metal with three or four asymmetric rollers that determine the curvature of the arc are positioned along the outer edge and/or on the flaps to process mixed sequences such as curves, v-curves, open and/or closed, spirals, ellipses, parabolas, folds and counter-folds in an automatic cycle to create closed geometric shapes in the longitudinal direction, more precisely that are circular, oval, rectangular, square, triangular, polygonal, conical, trapezoidal, etc. and equipped with grippers which hold the metal sheet clamped to be machined, in order to maintain the position in all phases, all in a single structure. The machine in question is managed by a continuous numeric control (CNC), an open system that is programmable by setting the movement cycles of the actuators depending on the processes to be performed. It 'also equipped with a cutting and profiling device with rotating circular tools to cut and bend both longitudinal edges in order to obtain complete and finished products such as ducts, downpipes, gutters, flashing, pipes, various coatings, etc. to meet production needs mainly in the civil, industrial, commercial, and agricultural sectors. |
