[0002] In sheet metal processing technology, sheet bending is a basic and crucial processing step. Bending refers to the processing technology that the metal sheet is deformed under the pressure of the upper or lower die of the bending machine and can present different angles according to the downward stroke of the upper die; the workpiece is placed on a concave die with a V-shaped opening, and the wedge-shaped tool (knife) presses the workpiece into the V opening to bend the plate to the required angle; the depth of the V groove is proportional to the thickness of the plate, the groove selection rule for thick plates: 4-10MM is 8-10 times the material thickness, and the groove selection rule for thin plates: 1-3MM is 4-6 times the material thickness;
