10. The use method of the efficient stamping die for machining the automobile sheet metal part, according to claim 1, is characterized in that: the using method comprises the following steps:

the method comprises the following steps: firstly, a punched plate passes through the space between two driving wheels (708) manually or by equipment, so that two connecting support plates (705) are in contact with the punched plate at two sides, and then a switch of a driving motor (4) is started;

step two: the rotation of the driving motor (4) can drive the rotation shaft (5) to rotate, the rotation shaft (5) can drive the rotating ring (16) to move up and down through eccentric rotation, the rotating ring (16) can drive the arc-shaped plate (801) and the connecting shaft (10) connected with the arc-shaped plate to move up and down through rotation, the connecting shaft (10) can drive the gravity sliding plate (11) and the upper die holder (13) to press down and lift up, and meanwhile, the ratchet plate (701) can be driven to move down in the downward moving process of the upper die holder (13);

step three: when the turntable (9) rotates for the other half circle, the connecting shaft (10) will be lifted, and in the lifting process, the ratchet plate (701) will be driven to move upwards, the ratchet plate (701) will drive the ratchet gear (704) to rotate, the rotation of the ratchet gear (704) drives the two driving wheels (708) to rotate relatively through the meshing of the gears (709), and the two driving wheels (708) will drive the sheet metal to be punched to be conveyed rightwards, so that the automatic feeding effect is realized;

step four: meanwhile, in the process that the connecting shaft (10) rises, the rotating plate (610) is driven to lift, because the rotating plate (610) is clamped with the pulling plate (609) in the process of moving downwards, the whole top column (601) and the whole top plate (603) are driven to lift in the lifting process, auxiliary pulling force is provided, and the formed sheet metal part is ejected and discharged;

step five: when the connecting shaft (10) is lifted to the highest point, the rotating plate (610) is in sliding contact with the sliding pin (612), the rotating plate (610) rotates to release the position of the pulling plate (609) through the lever principle, and then the ejection column (601) and the top plate (603) are reset through the contraction elastic force of the two telescopic springs (605);

step six: the material is punched by the first forming and the second trimming, and the formed product is collected through the feeding flow of the punched plate material to the inside of the material receiving box (2).
