step one, sheet metal part cladding, when the sheet metal part to be bent passes through the matching component (6) and is not bent, the sheet metal part is in a straight state, the sheet metal part to be bent is clad by utilizing the matching component (6) by means of external force, the bottom of the sheet metal part is attached to the surface of the anti-abrasion mechanism (7), when the sheet metal part is stamped, the sliding table (52) slides downwards on the surface of the sliding column (51), the cylindrical surface groove (55) at the bottom of the male die (53) is embedded with the middle part of the surface of the matching component (6), the anti-abrasion mechanism (7) is used for attaching and protecting the sheet metal part, and when the sheet metal part is bent, the male die (53) and the matching component (6) are used for carrying out cladding stamping on the sheet metal part;
step two, downward moving and bending, wherein the rod body (63) is pulled downwards by the elastic force of the spring (623), the inner side surface of the male die (53) is supported by the supporting plate (54), so that the impact deformation resistance of the male die (53) is enhanced, the male die (53) bends the sheet metal part downwards, the surface of the fixed press roll (65) is embedded with the cylindrical groove (55) at the bottom of the male die (53), the fixed press roll (65) bends the bending position of the sheet metal part in a punching way, the rotating roll (64) rolls at the position of the grooving (61), and meanwhile, the sliding sheet (622) slides on the inner side surface of the supporting column (3), so as to avoid instability when the rod body (63) and the fixed press roll (65) are subjected to downward rapid punching;
step three, sheet metal part protection, when a sliding table (52) moves downwards, a fixed pressing roller (65) bends the surface of the sheet metal part under the impact of a male die (53), the sheet metal part is stamped and deformed at the side surface of the male die (53), the surface of a plate body (74) is directly contacted with the bottom of the sheet metal part, the material flow of the sheet metal part is supported and protected by the plate body (74), a bending film (76) is arranged at the position between the fixed pressing roller (65) and the sheet metal part, and two ends of the bending film (76) are limited by a rubber roller (75), so that the surface of the sheet metal part is secondarily protected;
and fourthly, after bending, the surface of the plate body (74) is removed from the pressing force of the male die (53) to turn over and reset, the inner side surface of the pressing sheet (722) limits the two ends of the roller (723), the roller (723) rolls to enable the roller body (73) to rotate, the plate body (74) is connected with the bent rod (712) through the ball hinge (714), when the sheet metal part is bent and reset, the hydraulic resistance in the hydraulic cylinder (711) enables the plate body (74) to reset slowly, the resistance for resetting the plate body (74) is increased when the rubber strip (713) enters the hydraulic cylinder (711), and external force is applied to the sheet metal part to press and cover the sheet metal part to avoid rebound.
