10. A stamping method for kitchen wardrobe hardware, which is suitable for the stamping device for kitchen wardrobe hardware as claimed in claim 1, and is characterized in that: the method comprises the following steps:

step one: the working personnel pass through a material plate (41) needing to be punched and processed between two material feeding wheels (40), the two material feeding wheels (40) are driven to rotate in opposite directions through a rotary driving structure, so that the two material feeding wheels (40) drive the material plate (41) to move in the horizontal direction through friction force, the material plate (41) moves to the top of an operating table (2), when one side of the material plate (41) is contacted with a stop block (12), the stop block (12) limits the position of the material plate (41), and when the material feeding wheels (40) rotate, the material feeding wheels (40) cannot drive the material plate (41) to move through friction force;

Step two: the movable seat (9) is driven to move downwards through the lifter so that an upper stamping die (49) positioned at the bottom of the movable seat (9) moves downwards synchronously, at the moment, the movable seat (9) slides downwards relative to the stamping head (10), the stamping head on the upper stamping die (49) performs stamping on the material plate (41), the stamped waste material falls onto the material guide plate (18) through a stamping hole on the lower stamping die (7), the waste material slides on the material guide plate (18), and finally the waste material slides out of the material discharge groove (6) through the material discharge hole (19);

step three: when the upper stamping die (49) descends to the lowest position, the magnetic attraction unlocking unit releases the magnetic attraction fixing relation between the first connecting plate (13) and the first supporting part (14), after stamping is completed, the lifter drives the movable seat (9) to move upwards, after the stamping head on the upper stamping die (49) is separated from the material plate (41), along with continuous rotation of the feeding wheel (40), the feeding wheel (40) drives the material plate (41) to push the stop block (12) and the first connecting plate (13) to synchronously move, the first inserting plate (4) on the first connecting plate (13) is separated from the inserting hole (11), the limit on the position of the stamping head (10) is released by the first inserting plate (4), and after the first connecting plate (13) and the stop block (12) are moved to the preset position, the first connecting plate (13) is fixed relative to the first supporting part (14) through the magnetic attraction fixing structure again, and at the moment, the material plate (41) stops moving again, and the first inserting plate (41) moves synchronously to the stop block (12) and moves to the position above the object stage (16);

Step four: in the process that the movable seat (9) moves upwards, the movable seat (9) and the second inserting plate (17) move relative to the punching head (10), one side of the second inserting plate (17) slides on one side of the punching head (10), the second inserting plate (17) applies upward force to the punching head (10) due to friction so that the punching head (10) is always clung to the bottom of the baffle plate (38), when the movable seat (9) moves upwards to the initial position, the second inserting plate (17) moves to one side of the inserting hole (11), the elastic piece pushes the second inserting plate (17) to be inserted into the inserting hole (11), and the punching head (10) is fixed relative to the movable seat (9);

step five: the movable seat (9) is driven to move downwards through the lifter, the movable seat (9) drives the punching head (10) to move downwards synchronously through the second plugboard (17), the punching head (10) cuts off the part of the material plate (41) which is formed by punching from the material plate (41), and meanwhile, the upper punching die (49) performs punching processing on the material plate (41) positioned between the upper punching die (49) and the lower punching die (7) again;

step six: after the punching head (10) cuts off the punched part on the material plate (41) from the material plate (41), along with the continuous downward movement of the movable seat (9) and the punching head (10), a pressing device on the punching head (10) presses the punched part on the objective table (16) so as to synchronously move the objective table (16) and the punched part downwards, and when the punching head (10) and the movable seat (9) are lowered to the lowest position, the top horizontal position of the uppermost one of the punched parts on the objective table (16) is consistent with the top horizontal position of the operation table (2);

Step seven: after the stamping is finished, the lifter drives the movable seat (9) to move upwards again, when the stamping head on the upper stamping die (49) is separated from the material plate (41), the material plate (41) is driven by the material feeding wheel (40) to move again, one end of the material plate (41) moves one side of the stop block (12) again, when the material plate (41) is contacted with the stop block (12), the material plate (41) stops moving again, the stamping part on the material plate (41) moves to the top of one stamping part at the uppermost part of the objective table (16) again, and when the movable seat (9) moves to the initial position, the fifth step is executed in a return mode until the stamping of the whole material plate (41) is finished.
