c: a secondary stamping procedure: firstly, the attaching plate (19) is reset through a hydraulic cylinder (17), at the moment, the upper template (3) moves upwards under the action of a compression spring (34) on a guide column (33), then a driving roller (4) and a conveying belt (6) drive a clamping component (7) to move, punching materials on the clamping component (7) are moved to the upper part of a secondary punching die groove (23), and then the hydraulic cylinder (17) drives the upper template (3) to move, so that the secondary punching template (28) on the upper template (3) presses the primarily punched materials into the secondary punching die groove (23) to perform secondary punching work;
d: a punching procedure: firstly, resetting a laminating plate (19) through a hydraulic cylinder (17) to enable an upper template (3) to move upwards, then driving a clamping assembly (7) to move through a driving roller (4) and a conveying belt (6), moving a punching material on the clamping assembly (7) to the position above a punching die groove (24), and then driving the upper template (3) to move through the hydraulic cylinder (17) to enable a punching template (29) on the upper template (3) to be matched with the punching die groove (24) on a lower template (2) to punch a material subjected to secondary punching;
e: an edge forming process: firstly, resetting a laminating plate (19) through a hydraulic cylinder (17) to enable an upper template (3) to move upwards, then driving a clamping component (7) to move through a driving roller (4) and a conveying belt (6), moving a stamping material on the clamping component (7) to the position above an edge forming die groove (25), and then driving the upper template (3) to move through the hydraulic cylinder (17) to enable an edge forming template (30) on the upper template (3) to be matched with the edge forming die groove (25) on a lower template (2) to carry out edge forming work on the material subjected to a punching process;
f: a cutting and forming process: firstly, the attaching plate (19) is reset through the hydraulic cylinder (17), so that the upper template (3) moves upwards, then the driving roller (4) and the conveying belt (6) drive the clamping component (7) to move, the punching material on the clamping component (7) moves to the position above the cutting and forming die groove (26), then the hydraulic cylinder (17) drives the upper template (3) to move, so that the cutting template (31) on the upper template (3) moves downwards, the material subjected to the edge forming process is pressed into the cutting and forming die groove (26), and cutting and forming are carried out, and the finished material is obtained.
7. The stamping method of a continuous automatic stamping die according to claim 6, wherein, in the above steps, when the upper die plate (3) moves up and down, the upper die plate (3) keeps moving up and down vertically through the actions of the dovetail slide block (20) and the dovetail slide groove (21) and the actions of the guide groove (32) and the guide post (33).
8. The stamping method of the continuous automatic stamping die according to claim 6, wherein in the above steps, when the upper die plate (3) moves downwards, the stamping material is driven to move downwards, at the time, the stamping material drives the clamping plate (13) and the air cylinder (10) to move downwards, the air cylinder (10) keeps moving vertically up and down through the limit sliding block (15) and the limit sliding groove (16), the return spring (11) is compressed, and when the upper die plate (3) moves upwards, the return spring (11) drives the air cylinder (10) to return, so that the stamping material is separated from the lower die plate (2).
