[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5This utility model discloses a flexible stamping device for a safe door panel, comprising a base 5, a lower mold 17 fixed to the surface of the base 5, a stamping groove embedded in the surface of the lower mold 17, a top plate 10 fixed to the upper end of the base 5, and a stamping plate 2 connected to the bottom of the top plate 10 via two stamping cylinders 11. Specifically, the upper end of the stamping cylinder 11 is fixed to the top plate 10, and the lower end of the stamping cylinder 11 is connected to the stamping plate 2 to drive the stamping plate 2 to move up and down. An upper mold 20 is fixed to the lower surface of the stamping plate 2, and a stamping die head 13 corresponding to the stamping groove is provided on the lower surface of the upper mold 20. In use, the safe door panel 12 is placed between the upper mold 20 and the lower mold 17, and the stamping plate 2 is moved downward by the stamping cylinders 11, so that a specific shape or texture is stamped on the safe door panel 12 by the stamping die head 13 and the stamping groove. Furthermore, to prevent the safe door panel 12 from tearing during stamping, a spring 21 is connected between the stamping cylinder 11 and the stamping plate 2. Additionally, heating plates 16 are installed inside both the upper mold 20 and the lower mold 17. The spring 21 enables flexible stamping, allowing the safe door panel 12 to undergo a slow deformation process during stamping. This results in a more uniform stress distribution inside the safe door panel 12, preventing excessive stamping from causing tearing. The heating plates 16 are specifically positioned at the stamping groove and the stamping die 13 to heat these components. The preferred heating temperature is 310-330℃, with 320℃ being the most preferred. 320℃ is chosen as the heating temperature because at this temperature, the safe door panel 12 exhibits better plasticity and ductility, which is beneficial for stamping.

[0024] Furthermore, to facilitate quick positioning of the safe door panel 12, the base 5 is equipped with a positioning mechanism for positioning the safe door panel 12 on the surface of the lower mold 17. The positioning mechanism includes clamping mechanisms symmetrically arranged on both sides of the lower mold 17 for side positioning of the safe door panel 12, a rear baffle 18 fixed to the rear end of the lower mold 17 for rear-end positioning of the safe door panel 12, and a pressing mechanism 13 movably installed on the surface of the base 5 for front-end positioning of the safe door panel 12. The height of the rear baffle 18 is greater than that of the lower mold 17. When placing the safe door panel 12, the rear baffle 18 can quickly position the rear end of the safe door panel 12. Then, the clamping mechanism clamps it from both sides to achieve side positioning of the safe door panel 12. Finally, the pressing mechanism 13 presses against the front end of the safe door panel 12 to position the safe door panel 12 on the surface of the lower mold 17, which is convenient and quick.

[0025] In one embodiment of this application, such as Figure 1As shown, the clamping mechanism 6 includes a rotating shaft 8 rotatably mounted on the base 5, a clamping rod 7 fixed to the side of the rotating shaft 8, and a drive mechanism 9 fixed on the base 5 for driving the rotating shaft 8 to rotate. When the rotating shaft 8 rotates, it clamps the front end of the safe door panel 12 through the clamping rod 7, thereby facilitating the clamping and limiting of the safe door panel 12.

[0026] The surface of the base 5 is fixed with a guide column 1, the top plate 10 is fixed to the base 5 through the guide column 1, and the stamping plate 2 is slidably connected to the guide column 1. The movement of the stamping plate 2 is guided by the setting of the guide column 1.

[0027] like Figure 1 and Figure 3 As shown, the clamping mechanism includes a clamping cylinder 3 fixed on the base 5. The clamping cylinder 3 is symmetrically arranged on both sides of the surface of the base 5, and the extension end of the clamping cylinder 3 is fixed with a clamping plate 4. Before the safe door panel 12 is placed in, the two clamping plates 4 are far apart from each other to facilitate the quick placement of the safe door panel 12. After the safe door panel 12 is placed in, the clamping cylinder 3 extends to drive the two clamping plates 4 to move closer to each other. The safe door panel 12 is quickly centered and limited by clamping the two clamping plates 4.

[0028] like Figure 3 As shown, in one embodiment of this application, a guide tube 19 is fixed to the upper end of the stamping plate 2, and the lower end of the stamping cylinder 11 is movably disposed in the guide tube 19. The spring 21 is connected between the guide tube 19 and the lower end of the stamping cylinder 11. The guide tube 19 is provided to guide the sliding between the stamping cylinder 11 and the stamping plate 2 on the one hand, and to limit the axial movement of the spring 21 on the other hand.

[0029] To facilitate the removal of the safe door panel 12 from between the upper mold 20 and the lower mold 17 after stamping, a groove 15 is provided at the upper end of the base 5. The upper end of the groove 15 passes through the lower mold 17, and a belt conveyor mechanism 22 is installed in the groove 15 through a lifting mechanism 14. The lifting mechanism 14 is used to drive the belt conveyor mechanism 22 to move upward and lift the safe door panel 12. When the belt conveyor mechanism 22 rolls, it sends the safe door panel 12 out from the front end of the base 5. The belt conveyor mechanism 22 is a conventional structure and will not be described in detail here. During the stamping process, the belt conveyor mechanism 22 is hidden in the groove 15. After stamping, the drive mechanism 9 drives the rotating shaft 8 to rotate in the opposite direction, so that the clamping rod 7 rotates to the upper surface of the base 5. Then, the lifting mechanism 14 drives the belt conveyor mechanism 22 to move upward. When the belt conveyor mechanism 22 moves upward, it lifts the safe door panel 12 from the surface of the lower mold 17. Then, the belt of the belt conveyor mechanism 22 rolls and sends the safe door panel 12 out through the front end of the base 5, which is convenient to use.

[0030] In one embodiment of this application, the lifting mechanism 14 is a telescopic cylinder.

[0031] In one embodiment of this application, the drive mechanism 9 is an electric motor.

[0032] In summary, this utility model aims to provide a flexible stamping device for safe doors. By installing heating plates 16 in the stamping die 13 of the upper mold 20 and the stamping groove of the lower mold 17, the heating plates 16 heat the stamping die 13 and the stamping groove, allowing the safe door 12 to achieve good plasticity and ductility before stamping, reducing the risk of tearing. Simultaneously, a spring 21 connects the stamping cylinder 11 and the stamping plate 2, enabling flexible stamping and preventing excessive stamping that could cause tearing of the door panel. Furthermore, during the stamping process, the rear baffle 18 of the limiting mechanism initially limits the safe door 12 from the rear end. Symmetrically arranged clamping cylinders 3 drive clamping plates 4 to clamp the safe door 12 from the side, achieving lateral limiting. The motor in the pressing mechanism 6 drives the rotating shaft 8 to rotate, causing the pressing rod 7 to press against the safe door 12 from the front end, achieving rapid and stable limiting of the safe door 12. Finally, when the stamping is completed, the drive mechanism 9 drives the rotating shaft 8 to rotate in the opposite direction, so that the clamping rod 7 rotates to the surface of the base 5, releasing the restriction on the front end of the safe door panel 12. Then, the lifting mechanism 14 drives the belt conveyor mechanism 22 to move upward, lifting the safe door panel 12 from the surface of the lower mold 17. The safe door panel 12 can be automatically sent out from the front end of the base 5 by the rolling of the belt of the belt conveyor mechanism 22. No manual operation is required for unloading, which is convenient to use.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
