High efficiency on heavy plate bending operation Reduced overall dimensions and easiness of transportation on medium and big machines Having the two bottom rolls horizontally moving, means also a lower working height which requires a smaller foundation pit and less anchoring load (in the smallest models you don’t need foundation) On smaller models no need to place by digging. During operation (pre-bending and bending phases), the plate always keeps its horizontal position. So material move more easily The solid construction and the particular geometry of the 3R UHS enable to be used as a press brake bending machine The 3R UHS machine can fulfill the best pre-bending on every required diameter. The posibility of reducing the side rolls central distance (provided by the horizontal movement of the rolls) enables to increase the success of prebending while making smaller diameter bendings. Another important future of the 3R UHS machine is the operating system of the top forming roll. In fact, the top forming roll can be used as a traditional press brake allowing perfect re-rolling and calibration operations of the produced tubes In the same way it is also possible to obtain cones with heavy thickness by bending in several strokes the plate With some 3 and 4 rolls pyramidal machines it is necessary to tilt the top roll to allow the produced tube removal. On the 3R UHS machine this is not necessary and therefore it is much more easier to remove the finished tube Large working stroke allows to get best bending result Can bend more thicker plates compare to equivalent 3 or 4 roll machines SAE 1050 (CK 45-50) forged or hot rolled, induction hardened and polished steel rolls Double Speed Working system Conical Bending device Electronic balancing system for parellel movement of the rolls Standard Brake System Hydraulic Drop End
