Abstract
The utility model discloses a marine three-roller plate rolling machine in the field of shipbuilding. The marine three-roller plate rolling machine comprises an upper working roll, an upper working roll driving device, an upper working roll supporting device, a datum beam, lower working rolls, a lower working roll driving device, supporting bases and a lower roll assembly moving plate. The marine three-roller plate rolling machine is of numerical control and all-hydraulic control. The three work rolls can be driven independently and deflection compensation can be carried out on the three work rolls automatically. A hydraulic deflection compensation system is adjusted and controlled automatically and continuously through an absolute value encoder, a control valve and CNC. The two lower working rolls are supported by a common base, and therefore the transverse force is balanced. A lower roll edge-folding mold is not needed for folding edges, and therefore the cost of the mold is lowered. The marine three-roller plate rolling machine is easy to operate, and operating personnel just need to control the motion and the rotation motion of the upper working roll and the lower working rolls. The marine three-roller plate rolling machine has the advantages of being high in operation efficiency, easy to operate, convenient to maintain and the like, and is provided with the automatic deflection compensation system.
