Description

Technical Field

[0001] This utility model relates to the field of leveling automation, and in particular to a pure hydraulic single-roller controlled roller pressing mechanism. Background Technology

[0002] A leveling machine places the workpiece to be leveled between upper and lower roller assemblies, and achieves leveling through the pressure between the upper and lower rollers. In current leveling machines, the upper surfaces of the multiple lower rollers are all on the same horizontal plane, while the lower ends of the multiple upper rollers are on another horizontal plane. Furthermore, the upper rollers are moved up and down as a whole by a lifting module. This type of leveling machine is suitable for leveling workpieces of uniform thickness. However, when the thickness of the workpiece varies in different locations, only the flatness of the thickest part can be corrected, while the thinner parts cannot be leveled. Therefore, there is an urgent need for a leveling machine that can adjust the gap between the upper and lower rollers in real time at various positions, thereby achieving the leveling of workpieces with varying thicknesses.
