The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration.

[0026] As Figures 1 to 5 shown, a stamping and forming die for an automotive sheet metal part includes: a mounting plate 2, a scraping component 3 for scraping the sheet metal part after stamping, and an ejecting component 4 for ejecting the sheet metal part after stamping.

[0027] As is well known, a large amount of heat will be generated during the stamping process of sheet metal parts. After stamping, the sheet metal parts may adhere to the stamping head or the stamping table due to heat accumulation. At this time, the sheet metal parts are overheated and it is difficult for the staff to remove them, resulting in a reduction in work efficiency.

[0028] To prevent the sheet metal parts from adhering to the stamping table, a blanking component 4 is provided. The blanking component 4 is composed of a presser 41, a positioning rod 42, a sliding part 43, and a forming table 44. The presser 41 is fixedly connected to the lifting column 34. A cylinder 1 is installed at the top of the lifting column 34. The presser 41 is fixedly connected to the positioning rod 42. The sliding part 43 is fixedly connected to the positioning rod 42. The forming table 44 is slidably connected to the sliding part 43. The cylinder 1 drives the presser 41 to press down, so that the presser 41 presses the sheet metal parts into the forming table 44. At the same time, the positioning rod 42 also presses down and inserts into the forming table 44 to position the pressing position of the presser 41, helping the presser 41 to accurately stamp the sheet metal parts.

[0029] At the same time, the forming table 44 is provided with grooves adapted to the sliding part 43 and the positioning rod 42. A mounting plate 2 is installed at the bottom of the cylinder 1, and a plug rod is installed at the bottom of the mounting plate 2 and connected to the forming table 44. When the presser 41 drops to the bottom, the positioning rod 42 also drops to the bottom to position the pressing position of the presser 41. After the pressing is completed, the presser 41 rises, and the positioning rod 42 rises accordingly. The sliding part 43 at the bottom of the positioning rod 42 will contact the bottom of the stamped sheet metal parts and slightly lift it, so that it will not adhere to the stamping table, facilitating the staff to take it out.

[0030] The side of the sliding part 43 is designed with a rounded corner to prevent damage to the stamped sheet metal parts.

[0031] The blanking component 3 includes a fixed disk 31, a fixed rod 32, a rotating rod 33, and a lifting column 34. The fixed disk 31 is fixedly connected to the fixed rod 32. The fixed rod 32 is rotatably connected to the rotating rod 33. The rotating rod 33 abuts against the lifting column 34. When the cylinder 1 drives the presser 41 to descend for stamping, the rotating rod 33 remains stationary. When the cylinder 1 drives the presser 41 to rise, the lifting column 34 will touch one end of the rotating rod 33, causing it to rotate around the fixed rod 32, and the other end of the rotating rod 33 will scrape the surface of the presser 41, so that the sheet metal parts adhering to the surface of the presser 41 will fall off, facilitating the staff to take the materials.

[0032] At the same time, the rotating rod 33 is a horizontal L-shaped rod, and the connection between the rotating rod 33 and the fixed rod 32 is connected by a torsion spring. The lifting column 34 touches the unbent end of the rotating rod 33, and the bent end of the rotating rod 33 scrapes the surface of the presser 41, which is more conducive to blanking. At the same time, when the lifting column 34 descends, the rotating rod 33 returns to its original position and will not restrict the presser 41.

[0033] A pneumatic pump 5 is installed on the top of the molding table 44, and the blowing direction is towards the center of the molding table 44. A collection box 6 is provided at the bottom of the molding table 44. After stamping, the stamping debris will remain on the surface of the stamping table. By blowing air through the pneumatic pump 5, the debris will rotate around the central slot of the molding table 44 and fall into the slot opened on the molding table 44 for positioning the positioning rod 42, and then fall into the collection box 6, preventing the debris from damaging the next stamped sheet metal part.

[0034] Working principle:

[0035] The cylinder 1 drives the presser 41 to press down, so that the presser 41 presses the sheet metal part into the molding table 44. At the same time, the positioning rod 42 also presses down and inserts into the molding table 44 to position the pressing position of the presser 41, helping the presser 41 to accurately stamp the sheet metal part. When the presser 41 reaches the bottom, the positioning rod 42 also drops to the bottom to position the pressing position of the presser 41. After the pressing is completed, the presser 41 rises, and the positioning rod 42 rises accordingly. The sliding part 43 at the bottom of the positioning rod 42 will contact the bottom of the stamped sheet metal part and slightly lift it, so that it will not adhere to the stamping table, facilitating the staff to take it out. When the cylinder 1 drives the presser 41 to descend for stamping, the rotating rod 33 remains stationary. When the cylinder 1 drives the presser 41 to rise, the lifting column 34 will touch one end of the rotating rod 33, causing it to rotate around the fixed rod 32, and the other end of the rotating rod 33 will scrape the surface of the presser 41, so that the sheet metal part adhering to the surface of the presser 41 will fall off, facilitating the staff to take the material.
