The hydraulic rolling machine has a compact and reasonable structure and is easy to operate. The metal plate passes through the three work rolls of the plate rolling machine, with the help of the lower pressure of the upper roll and the rotational movement of the lower roll, the metal plate is continuously bent in multiple passes, resulting in permanent plastic deformation, and rolled into cylinders, arcs, cones Tubes and other workpieces, with high machining accuracy and high work efficiency. The hydraulic rolling machine adopts an advanced integrated hydraulic system to ensure the high reliability of the plate bending machine hydraulic rolling machine in operation.
