Description

Technical Field

[0001] The utility model relates to the technical field of metal processing, in particular to a metal plate bending tool. Background Art

[0002] Bending is the process of metal sheets undergoing elastic deformation and then plastic deformation under the pressure of the upper or lower die of the bending machine. At the beginning of plastic bending, the sheet is free to bend. As the upper or lower die applies pressure to the sheet, the sheet gradually comes close to the inner surface of the lower die forming groove, and the radius of curvature and bending arm gradually decrease. Continue to apply pressure until the stroke ends, so that the upper and lower dies are in full contact with the sheet at three points, thus completing the sheet bending action.

[0003] An existing metal sheet bending tool (Announcement No.: CN221064003U) has at least the following disadvantages: when the upper and lower dies are pressed, due to the certain toughness of the metal sheet, when the top is subjected to the extrusion force, the sheet will have a certain deviation, resulting in the change of the bending position of the metal sheet, which will affect the product quality, and when the mold needs to be replaced and adjusted, workers need to use tools to remove the screws to operate, which is very troublesome.
