Metal plates are divided into thin plates and thick plates. Thin metal plates are easier to bend and do not require much effort, while thick metal plates are generally bent with the help of bending machines. A Chinese patent discloses an efficient metal plate bending tool (authorization announcement number CN218108936U). This patented technology can be used to bend longer metal plates by setting a second set of electric push rods, a pressure plate, a threaded sleeve, an adjustment rod and a load-bearing plate. During operation, the speed of the metal sheet in the bending area of ​​the workbench can be increased through the ball bearings on the bearing plate, and the pressure plate is driven downward by starting the second set of electric push rods to contact the surface of the metal sheet, and the remaining part of the metal sheet is mechanically stabilized to avoid manual support, which can reduce the intensity of manual labor, save time and effort, and is easy to use. However, the above patent can only perform simple bending on the metal sheet, and in the actual processing process, some metal sheets need to be bent into an arc shape, and the above bending structure cannot perform arc bending on the entire metal sheet.
