[0002] A leveling machine, also known as a flattening machine, plate leveling machine, straightening machine, or straightening machine, is mainly used to straighten various specifications of sheet metal and sheared sheet metal. It is suitable for leveling various cold and hot rolled sheet metal. By squeezing strips or sheets of a certain thickness through upper and lower rollers, a flat effect is achieved. Generally, leveling machines are arranged in a four-upper-five-lower or three-upper-four-lower configuration, and are equipped with moving rollers at the front and rear. Due to its advanced technology, high leveling precision, wide process range, high degree of automation, and good reliability under high intensity, it has been widely used in industry. When leveling sheet metal, the sheet metal usually needs to be neatly placed on the worktable first, and then leveled according to the requirements. However, due to the large size of the material, it is difficult to place it accurately and neatly, which will cause the material to shift during the leveling process, making it impossible to ensure uniform leveling, and thus the sheet metal does not meet the production requirements.
