Three-roll plate- rolling machine

Abstract

The invention discloses a three-roll plate- rolling machine and belongs to the field of machine manufacturing. The three-roll plate-rolled machine comprises a left support, a right support, one upper roll, two lower rolls and a driving device, the upper roll and the lower rolls are arranged between the left support and the right support respectively and are connected with the driving device, four rollers are arranged on the portions, between the upper roll and the lower rolls, of the left support and the right support respectively, and the rollers make contact with a lubricating oil supply device. Four rollers are arranged on the portions, between the upper roll and the lower rolls, of the left support and the right support respectively, during the process of rolling a plate, the plate can be controlled in position in real time by rolling of the rollers, and therefore the plate can run at a normal rolling route, and the disqualification of the formed product caused by offset is avoided; the lubricating oil supply device is arranged beside the rollers and can supply the oil to the rollers and lubricate the rollers in real time in a contact mode, the friction between the rollers and the plate is reduced and the service life of the rollers can be prolonged.

Description

technical field [0001] The invention relates to a plate rolling machine, specifically a three-roller plate rolling machine, which belongs to the field of mechanical manufacturing. Background technique [0002] The plate rolling machine is a common shaping machine tool for continuous point bending of plates, and is widely used in petrochemical shipbuilding, pressure vessels, machinery manufacturing and other industries. The upper roll of the plate rolling machine is at the symmetrical position in the center of the two lower rolls, and the hydraulic oil in the hydraulic cylinder acts on the piston to perform vertical lifting movement, and the final gear of the main reducer drives the gears of the two lower rolls to mesh and rotate to provide the rolling plate. torque. With the help of the pressing down of the upper roller and the rotating movement of the lower roller, the metal plate is continuously bent through multiple passes, resulting in permanent plastic deformation, and...

AI Technical Summary

Problems solved by technology

The three-roll plate rolling machine in the prior art usually adopts the external force control method to control the plate during the rolling process. Since the plate rolling machine cannot perform real-time control on the plate, once a slight difference occurs during the operation of the upper roll and the lower roll In the case of synchronization, the plate will be offset, which will affect the final forming accuracy of the plate and easily cause damage to the equipment
