HPBM-450-30-3RT 3Rolls Hydraulic Translating Type Plate Bending Machine

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
