[0044] Example 1: The stamping die, the rounding die, and the rounding die are respectively installed on the corresponding press. The stamping process is performed first, followed by the rounding process, and finally the rounding process.
[0045] As attached Figure 1-2 As shown, the worker places the hinge plate 100 into the board groove 3, starts the press, and the press head drives the extrusion die 2 to press down. The U-shaped die head 7 presses the hinge plate 100 into the stamping groove 4, making the bottom of the hinge plate 100 U-shaped. The press drives the extrusion die 2 to move up.
[0046] As attached Figure 3-4As shown, the stamped hinge plate 100 is placed into the second forming female mold 14. The worker inserts the auxiliary forming rod 11 into the U-shaped area of the hinge plate 100. The press head of the press drives the rounding male mold 13 to press down. The arc-shaped pressing surface 10 presses one side of the U-shaped area of the hinge plate 100 onto the outer circumference of the auxiliary forming rod 11 to form the hinge bushing. After the stamping is completed, the rounding male mold 13 moves up, the worker pulls out the auxiliary forming rod 11, and transports the hinge plate 100 to the next station.
[0047] Arc-shaped transition surfaces 5 are provided on both sides of the inlet end of the stamping groove 4, so that the hinge plate 100 is squeezed into the stamping groove 4 more smoothly.
[0048] As attached Figure 5-6 As shown, the lower forming die 21 is installed on the worktable of the press, and the upper forming die 23 is installed on the press head. The stamped missile launcher hinge 100 is placed into the forming groove 24, and the bushing of the missile launcher hinge 100 is located in the rounding groove 25. The adjusting block 22 is inserted to the bottom along the inner wall of the forming groove 24, and the missile launcher hinge 100 is kept vertical. The press drives the upper forming die 23 to press down, and the missile launcher hinge 100 is located in the forming area. The upper forming die 23 is pressed down until it contacts the bottom surface of the forming groove 24. Through the cooperation of the rounding groove 26 and the rounding groove 25, the bushing of the missile launcher hinge 100 is shaped into place. After the forming is completed, the upper forming die 23 is lifted up and reset, and the operator removes the missile launcher hinge 100.
[0049] When the adjusting block 22 is installed, it is guided by the guide slope 28 to avoid collision.
[0050] When the upper mold 23 is pressed down, it is guided by the mold closing slope 29, so that the upper mold 23 enters the lower mold 21 more smoothly.
