A fixing ring 706 is provided on the outside, and a disassembly ring 707 is provided on the top of the fixing ring 706. The fixing ring 706 is located below the fixing column 705. The disassembly ring 707 is in contact with the fixing ring 706 in a natural state. The inner side of the disassembly ring 707 is slidingly connected to the outer side of the fixing column 705.

[0030] Embodiment 2

[0031] like Figure 2-Figure 3 As shown, the utility model proposes a stamping forming mechanism for automobile high-strength steel plates. Compared with the first embodiment, this embodiment introduces the structure of the auxiliary disassembly and assembly mechanism in detail.

[0032] Specifically, the auxiliary disassembly and assembly mechanism includes a semicircular slide rail 722 arranged on the top of the working plate 1, a sliding rod 721 is slidingly arranged on the inner side of the semicircular slide rail 722, a rotating rod 717 is arranged on the top of the sliding rod 721, a magnetic block 720 is arranged on the end of the rotating rod 717, a connecting block 714 is arranged on the side of the rotating rod 717, a telescopic tube 715 is arranged on the side of the connecting block 714, the telescopic tube 715 is an elastic hose that can be bent, a spring 716 is arranged on the outer side of the telescopic tube 715, a rotating rod 1 711 is arranged on the end of the telescopic tube 715 away from the rotating rod 2 717, and two sliding rods 721 are respectively connected to the rotating rod 1 711 and the rotating rod 2 717, so that the rotating rod 1 711 and the rotating rod 2 717 are more stable when rotating, and can support the two rotating rods at the same time, thereby supporting the stamping die 701, which is convenient for stamping work. A magnet 1 719 is provided at one end of magnet 1 711 close to magnet 2 720, and the sides of magnet 2 720 and magnet 1 719 facing each other are opposite poles and can attract each other. A rotating assembly is provided on the inner side of rotating rod 1 711, and the rotating assembly includes a fixed shaft 718 arranged on the top of the working plate 1, and a rotating ring 1 712 is rotatably provided on the outer side of the fixed shaft 718, and the end of the rotating ring 1 712 away from the fixed shaft 718 is connected to the side of the rotating rod 1 711, and a rotating ring 2 713 is rotatably provided on the inner side of the rotating ring 1 712, and the inner side of the rotating ring 2 713 is rotatably connected to the outer side of the fixed shaft 718, and the end of the rotating ring 2 713 away from the fixed shaft 718 is connected to the side of the rotating rod 2 717. Since the rotating rod 1 711 and the rotating rod 2 717 both rotate with the fixed shaft 718 as the center, the two sliding rods 721 also rotate with the fixed shaft 718 as the center in the semicircular slide rail 722.

[0033] In summary, when the utility model is in use, when installing the stamping die 701, the rotating rod 1 711 and the rotating rod 2 717 are rotated close to one end of the spring 3 716 to move them toward each other, thereby separating the two magnetic blocks at the other ends of the rotating rod 1 711 and the rotating rod 2 717 and detaching them from the fixed column 705, and then aligning the empty groove in the mounting column 702 on the stamping die 701 to be installed with the semicircular block 704 and pressing downward, the trapezoidal clamping block 708 will move toward the outside of the fixed column 705 through the spring 2 709 when the arc surface of the semicircular block 704 moves. At this time, the spring 2 709 is compressed, and after detaching from the arc surface, the trapezoidal clamping block 708 will be clamped at the bottom of the semicircular block 704 under the action of the spring 2 709. , and then release the rotating rod 1 711 and the rotating rod 2 717. Driven by the spring 3 716, the two magnetic blocks are re-adsorbed together, thereby fixing the position of the trapezoidal block 708 for convenient stamping. When the stamping die 701 needs to be disassembled, the two rotating rods are opened again, and the mounting column 702 is continued to be pressed down. When the trapezoidal block 708 contacts the disassembly ring 707, it moves outward and moves to the bottom of the disassembly ring 707. Then the mounting column 702 is pulled up, and the trapezoidal block 708 drives the disassembly ring 707 to rise together. After contacting the semicircular block 704, continue to pull up to make the trapezoidal block 708 disengage from the disassembly ring 707, thereby disengaging from the semicircular block 704, so that other stamping dies 701 can be replaced.

[0034] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
