Plate rolling machines have different types due to different fields of use. According to the number of rollers, they are divided into three-roller plate rolling machines and four-roller plate rolling machines. Three-roller plate rolling machines are divided into symmetrical three-roller plate rolling machines, horizontal downward adjustment three-roller plate rolling machines, arc downward adjustment plate rolling machines, upper roller universal three-roller plate rolling machines, and hydraulic CNC plate rolling machines. From the perspective of transmission, they are divided into mechanical and hydraulic types. From the development of plate rolling machines, the upper roller universal type is the most backward, the horizontal downward adjustment type is slightly advanced, and the arc downward adjustment type is the most advanced.

Working principle of plate rolling machine

The working principle of plate rolling machine is to move the working roller through external forces such as hydraulic pressure and mechanical force, so as to bend or roll the plate into shape. Specifically, the upper roller of the plate rolling machine is in the central symmetrical position of the two lower rollers, and the hydraulic oil in the hydraulic cylinder acts on the piston to make vertical lifting and lowering movements, and the final gear of the main reducer drives the two lower roller gears to mesh and rotate, thereby realizing the bending and rolling of the plate.

Specifications and standards of plate rolling machines

The specifications and standards of plate rolling machines mainly include the following parameters:

Maximum thickness of plate rolling (mm): refers to the maximum plate thickness that the plate rolling machine can handle.

Maximum width of plate rolling (mm): refers to the maximum plate width that the plate rolling machine can handle.

Sheet yield limit: refers to the ability of the plate to roll the minimum roll diameter when the maximum sheet thickness and width are rolled according to the specified yield limit in a cold state.

Rolling speed (M/min): refers to the rolling speed of the plate rolling machine.

Minimum diameter of full-load rolling (mm): refers to the minimum diameter that the plate rolling machine can roll under full load.

Upper shaft diameter (mm): refers to the diameter of the upper shaft of the plate rolling machine.
