Embodiment
[0050] During the hot forming process of the high-strength steel plate 140, a circular through hole with a diameter of 10mm is punched out at the riveting position of the steel plate.
[0051] like figure 1 As shown, the punch 110, the positioning hydraulic cylinder and the integral lower die base are coaxially arranged, and the positions of the hydraulic cylinder and the fixed lower die base 180 are fixed; The diameter of the small circle on the surface is 8mm, the inclination angle of the bus bar is 45°, the height is 15mm, the diameter of the internal cooling liquid channel is 2.5mm, and the distance between the axis plane and the lower surface of the punch is 3mm. The punch 110 is placed in the center hole of the blank holder 120 for sliding connection. The blank holder 120 is a ring-shaped structural member with a height of 15mm, an outer diameter of 20mm, an inner diameter of 10mm, and a piston 150 with a diameter of 10mm. The cylinder 160 has a diameter of 14 mm and a ...
