According to any one of claims 1-9, the forming method of a forming device of a windshield mesh shrapnel for a panoramic sunroof of an automobile, is characterized in that it comprises the following steps; Step 1. When it is necessary to use the forming device of the shrapnel to shape the shrapnel, first place the plate to be processed into the delivery bin (11), and then start the first drive motor (12) and the first electric telescopic rod (14) ), drive the installation frame (15) to move downward through the first electric telescopic rod (14), and drive the guide roller (16) to move downward until the bottom of the guide roller (16) contacts the top of the plate, and then pass the first A drive motor (12) drives the conveying roller (13) to rotate, and drives the plate to move between the conveying roller (13) and the guide roller (16), and simultaneously passes the conveying roller (13) and the guide roller (16) to the plate. Straightening; Step 2: After the plate is transported to the support platform (21) by the conveying and straightening mechanism (1), start the second driving motor (215) to drive the two-way threaded rod (23) to rotate, and then the two moving frames (24) The distance between is adjusted so that the distance between the two cutting knives (27) is adjusted, so that the distance between the two cutting knives (27) is adjusted according to the length of the sheet required for shrapnel forming; Step 3. After the distance adjustment between the two moving frames (24) is completed, start the second electric telescopic rod (210) to adjust the distance between the two punching blocks (212), and then start the first cylinder (25) Drive punching block (212) and cutting knife (27) to move downward simultaneously; Step 4, when the punching block (212) and the cutting knife (27) move downward, the fixed rod (28) first contacts with the upper surface of the plate, and the position of the plate is fixed by the fixed rod (28), and then along with The punching block (212) and the cutting knife (27) continue to move down, driving the spring (29) to compress, until the punching block (212) and the cutting knife (27) finish punching the plate, they can pass through the first cylinder ( 25) Drive the punching block (212) and the cutting knife (27) to move upwards, and simultaneously drive the fixed rod (28) to move upwards; Step 5, start the second cylinder (213) to drive the push plate (214) to move towards the direction close to the workbench (31), and push the punched plate to the workbench (31) through the push plate (214); Step 6. Drive the tooth ring (41) to rotate in the installation groove (313) through the operating rod (410), and at the same time drive the second gear (42) to rotate, so that the first tooth plate (44) and the second tooth plate The tooth plates (45) all move towards the direction of the center of the workbench (31) until the two limiting plates (46) and the two rollers (48) are respectively in contact with the four sides of the plate, and the alignment of the plate can be completed. Adjust the position of the plate so that the plate is located at the center of the workbench (31), and the bottom surface of the side of the plate fits the top surface of the bent plate (39); Step 7. Start the two-way cylinder (32) to drive the racks (35) away from each other through the installation rods (34) on both sides, and then drive the first gear (37) to rotate, and drive the bending plate through the first gear (37) (39) Flip towards the direction close to the plate, and then realize the side bending of the plate; Step 8. When the bending plate (39) rotates, the pointer (311) is driven to move, and the bending angle of the bending plate (39) can be marked by the position of the pointer (311) on the scale (310), and then there are It is beneficial to bend the plate at different angles according to the demand; Step 9. After the shrapnel is formed and manufactured, drive the limit plate (46) and the roller (48) to reset through the operating rod (410), and then make the bidirectional cylinder (32) drive the bending plate (39) to reset, when the second The cylinder (213) pushes the next punched plate onto the workbench (31), and at the same time pushes out the last formed shrapnel, and the reciprocating cycle realizes continuous forming.
