[0002] The rear cover of an SUV car is a special-shaped part. The rear cover of the SUV car includes a rear cover (1). The rear cover (1) is punched to form a rear glass mounting hole (3) for assembling a rearview mirror. The rear cover (1) is also punched to form two sets of symmetrical taillight slots (6) for embedding taillights. The rear cover (1) is punched to form a license plate mounting seat (4) for mounting a license plate. The license plate mounting seat (4) is punched to form a license plate bolt mounting hole (2) for the license plate mounting screw to pass through. The side wall of the license plate mounting seat (4) near the rear glass mounting hole (3) is punched to form a license plate light mounting hole (5) for mounting a license plate lighting lamp (such as Figure 10 shown).

[0003] At present, the stamping die can form the rear hood (1), rear glass mounting hole (3), license plate mounting seat (4) and tail light slot (6) at one time, but the license plate bolt mounting hole (2) and license plate light mounting hole (5) still need different dies for stamping. The license plate bolt mounting hole (2) and license plate light mounting hole (5) are not convenient to be formed on the same set of dies, and the license plate bolt mounting hole (2) and license plate light mounting hole (5) may produce curling phenomenon during the molding.

When the second spring 1015 is in a natural state, the inclined portion of the upper end of the trapezoidal tool 1014 is the blade position and is located outside the punch rod 109. After the bottom of the punch rod 109 punches the license plate bolt mounting hole 2, the trapezoidal tool 1014 moves downward, and the inclined part of the lower end of the trapezoidal tool 1014 pushes the trapezoidal tool 1014 to move into the slide groove 1016 through contact. After the trapezoidal tool 1014 moves to the bottom of the license plate bolt mounting hole 2, the second spring 1015 of the chamfering tool drives the trapezoidal tool 1014 to move to the outside of the punch rod 109, and then the upper die 8 moves slowly upward, and the punch rod 109 moves slowly upward. At the same time, the motor 101 of the drive assembly of the synchronous drive assembly drives the horizontal shaft 108 to rotate, and the horizontal shaft 108 drives the second The bevel gear 1011 rotates, the motor 101 drives the first bevel gear 104 to rotate, the first bevel gear 104 drives the punch rod 109 or the straight shaft 1010 to rotate, and the belt 107 drives the four sets of punch rods 109 to rotate, and the punch rod 109 drives the trapezoidal tool 1014 of the chamfering tool to rotate to grind the curling edge, and the trapezoidal tool 1014 slides into the slide groove 1016 while grinding, and grinds the curling edge produced by the punching of the punch rod 109, thereby reducing the impact of the curling edge on the discharging of the rear cover 1 and reducing the jamming phenomenon.

The first spring 91 is fixedly installed at equal intervals between the end of the wedge block 93 near the upper die 8 and the outer wall of the upper die 8. When the upper die 8 moves to the lowest end, the push assembly is slidably connected to the punching assembly. A transverse groove 96 is formed on the side wall of the license plate mounting seat slot 74 near the taillight insert 72. When the first spring 91 is in a natural state, the inner end of the punch plate 92 is located to the right of the two sets of punch rods 109 on the left.
