Description

Technical Field

[0001] The utility model relates to the technical field of metal sheet processing, in particular to a metal sheet precision leveling machine. Background Art

[0002] Metal sheets are a very important raw material in modern equipment. Many equipment and tools are made of metal sheets for lining and surface parts. When processing metal sheets, precision leveling machines are needed to level them.

[0003] For example, a metal sheet precision leveling machine with the authorization announcement number CN219944190U includes a lifting member, a conveying member, a rotating mechanism and a limiting mechanism. The middle part of the lifting member is provided with a conveying member, and the top of the conveying member is provided with a rotating mechanism. Although the above-mentioned document can realize the rapid and thorough cleaning of the working roller or roller, facilitate the mechanical inspection, and ensure the leveling accuracy; however, in the process of using the precision leveling machine, the metal sheet is leveled by placing the metal sheet between two upper and lower rollers. Due to the gap between the upper and lower rollers, the metal sheet is leveled. The distance is fixed, and the distance between the two rollers cannot be adjusted, resulting in the precision leveling machine being able to level only metal sheets of the same thickness, thereby reducing the leveling range of the metal sheets by the precision leveling machine; at the same time, when the precision leveling machine is leveling the metal sheets, there is no guide structure inside the precision leveling machine to guide the precision leveling machine to avoid the position of the metal sheets shifting when placing them, resulting in inconvenience in discharging the metal sheets after the metal sheets are leveled, thereby reducing the working effect of the precision leveling machine.

[0013] The double-headed screw is driven to rotate by the handwheel in the guide device, and the threaded block of the double-headed screw moves. The two threaded blocks slide in the slide groove at the bottom of the box, and the two threaded blocks drive the vertical plate to move. The distance between the two vertical plates is adjusted to be the same as the width of the metal sheet to be leveled.
