Description

Technical Field

[0001] The utility model relates to the technical field of plate rolling machines, in particular to a marine three-roll plate rolling machine. Background Art

[0002] A marine plate rolling machine is a type of plate rolling machine. The structural type of the marine plate rolling machine is three-roll symmetric. The upper roll makes a vertical lifting movement at the central symmetric position between the two lower rolls, which is obtained by the hydraulic oil in the hydraulic cylinder acting on the piston rod, and is hydraulically driven. The two lower rolls make a rotational movement, and the output gear of the speed reducer meshes with the lower roll gear to provide torque for rolling the plate.

A hydraulic rod is movably installed on the side wall of the upper roll body through a rotating shaft.

First motors are fixedly installed on both the left and right sides of the upper end surface of the base. A gear is fixedly installed at the rear end of the first motor. Support frames are movably installed on both the left and right sides of the upper end surface of the base. A slider is fixedly installed in the middle of the lower end surface of the support frame. A tooth groove is opened on the front side of the lower end surface of the support frame, and a rack is fixedly installed on the upper end surface of the inner cavity of the tooth groove; during use, the plate is first inserted between the pre-rolling lower shaft and the pre-rolling upper shaft, and the motor drives the pre-rolling lower shaft to rotate to pre-roll the plate. After the plate is pre-rolled, it moves to the upper end of the lower roll body. The hydraulic rod drives the upper roll body to move downward and be located above the plate.
