Abstract

The invention provides a large three-roller plate rolling machine which comprises a rack, a main transmission device, an upper cross beam mechanism, a lower cross beam mechanism, a hydraulic system and an electrical system; the main transmission device comprises an anti-rotation and anti-swing mechanism, a low-speed large-torque radial plunger motor and a shaft-mounted reduction gearbox; the bracket comprises an oil cylinder, a lower working roller central moment adjusting device and a guide device; the upper cross beam mechanism comprises an upper cross beam, an upper working roller, an upper support roller component, an upper roller support device and an upper support roller inclined wedge adjusting system; the lower cross beam mechanism comprises a lower cross beam, a lower working roller, a lower support roller component, a lower roller support device and a lower support roller inclined wedge adjusting system; the electrical system comprises a PLC, a touch screen, a relay, a contactor, a non-contact type linear displacement sensor and a proportional solenoid directional valve. The large three-roller plate rolling machine has the technical effect that the large three-roller plate rolling machine can be used for manufacturing large ship bodies.

Description

technical field [0001] The invention relates to a large three-roller plate bending machine, which belongs to the field of mechanical equipment. Background technique [0002] Rolling Machine is a shaping machine tool for continuous point bending of plates, and has the function of rolling plates of different shapes such as O-shaped, U-shaped, and multi-section R. [0003] Three-roll plate rolling machine has mechanical type and hydraulic type: Mechanical three-roll plate rolling machine is divided into symmetrical and asymmetrical. The sheet metal can be rolled into circular, curved and conical workpieces within a certain range. The working principle of the symmetrical three-roller plate bending machine is that the upper roller acts on the piston to perform vertical lifting movement through the hydraulic oil in the hydraulic cylinder at the symmetrical position in the center of the two lower rollers, and the final gear of the main reducer drives the gears of the two lower rol...
