Description

Technical Field

[0001] This utility model relates to the field of metal sheet leveling machine technology, and more specifically, to a limiting mechanism for a metal sheet leveling machine. Background Technology

[0002] A leveling machine, also known as a sheet metal leveling machine, flattening machine, straightening machine, or straightening machine, is mainly used for straightening sheet metal of various specifications and sheared sheets. It is suitable for leveling various cold-rolled and hot-rolled sheets. During the process of pushing the metal sheet into the leveling machine, the moving sheet metal is prone to shifting, affecting the leveling quality.

[0003] A search revealed that utility model patent CN221388553U discloses a limiting mechanism for a metal sheet leveling machine, including a bracket. One end of the bracket is fixedly connected to the leveling machine body. Guide rollers are movably connected to the inner walls of both sides of the bracket for conveying the sheet metal. Two connecting plates are fixedly connected to the bottom of the bracket, and a movable seat is movably connected between the two connecting plates. A push block is fixedly connected to the top of the movable seat and extends above the bracket. The bracket is equipped with a driving component that moves the push block so that the push block pushes the sheet metal into the leveling machine body. This patent not only allows the limiting strip to contact and fit with both sides of the sheet metal, limiting the sheet metal from shifting during movement, but also reduces manual operation through the use of gears and racks, saving time and effort and making the limiting method more convenient. However, the above patent still has the following shortcomings: during the process of using the limiting strip to limit the plate, there will be friction between the side of the plate and the limiting strip, which will affect both the plate and the limiting strip. In addition, the push block is driven by the threaded engagement between the screw and the moving seat, and the push block can only move back and forth along the axial direction of the screw, which is not convenient for continuous feeding. Therefore, a limiting mechanism for a metal plate leveling machine is proposed. Utility Model Content
