Detailed Implementation

[0029] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.

[0030] like Figures 1-7 As shown, a stamping die for metal stamping according to one embodiment of the present invention includes a body mechanism 1 and a workpiece limiting mechanism 2. The body mechanism 1 includes a base 11, a mounting hole 12, a lower die 13, and an upper die 15. The mounting hole 12 is formed on the base 11 in a through-hole manner. The lower die 13 is installed at the upper opening of the mounting hole 12. The upper die 15 is installed above the lower die 13 in a corresponding manner. The body mechanism 1 also includes a first mounting component disposed between the base 11 and the lower die 13, and a second mounting component disposed between the base 11 and the upper die 15. The workpiece limiting mechanism 2 includes a pair of limiting plates 21 mounted on the base 11, and an adjusting component disposed between the base 11 and the limiting plates 21.

[0031] When using this stamping die for metal stamping, the lower die 13 and upper die 15 are replaced according to the required opening size of the metal sheet. The lower die 13 is installed on the base 11 via a first mounting component, and the upper die 15 is installed on the base 11 via a second mounting component. This allows the upper die 15 to perform the opening operation on the sheet metal placed on the lower die 13, enabling different openings on the sheet metal. This facilitates the replacement of the lower die 13 and upper die 15 with the corresponding hole diameter. The first and second mounting components make the replacement of the lower die 13 and upper die 15 convenient, improving the practicality of the stamping die. When opening a hole in the sheet metal, the sheet metal is placed between a pair of limiting plates 21. The spacing between the pair of limiting plates 21 is adjusted by an adjusting component, causing the pair of limiting plates 21 to clamp and position the front and rear sides of the sheet metal, thereby restricting the movement of the sheet metal and ensuring that the sheet metal does not shift when the upper die 15 opens a hole, improving the accuracy of the opening.

[0032] like Figure 3 , Figure 4 and Figure 6 As shown, the first mounting component includes a mounting groove 16, a limiting groove 17, a limiting cylinder 18, and a first screw 19. The mounting groove 16 is opened at the upper end of the mounting hole 12, and the limiting groove 17 is opened on the bottom wall of the mounting groove 16.

[0033] like Figure 3 and Figure 4As shown, the limiting cylinder 18 is integrally formed on the bottom of the lower mold 13. The limiting cylinder 18 is sleeved in the limiting groove 17, thereby limiting the movement of the lower mold 13 after installation through the cooperation of the limiting groove 17 and the limiting cylinder 18, and improving the stability of the lower mold 13 after installation.

[0034] like Figure 3 and Figure 4 As shown, the first screw 19 passes through the limiting cylinder 18 from the top of the lower die 13 and is threaded into the bottom wall of the limiting groove 17. The upper end of the first screw 19 is flush with the upper surface of the lower die 13. The lower die 13 can be fixed to the base 11 by the first screw 19, ensuring the stability of the lower die 13 after installation, making the structure stable during stamping. At the same time, the easy disassembly and assembly of the first screw 19 makes it convenient to replace the lower die 13.

[0035] like Figure 3 and Figure 4 As shown, the lower die 13 is installed in the mounting groove 16, and a buffer pad 110 is installed between the mounting groove 16 and the lower die 13. The buffer pad 110 can effectively buffer the impact force received by the lower die 13 when the sheet metal is stamped by the lower die 13.

[0036] like Figure 3 and Figure 5 As shown, the second mounting assembly includes a mounting frame 14, a mounting plate 111, a second screw 112, a drive device 113, and a guide rod 114. The front and rear side panels of the mounting frame 14 are fixed to the front and rear side walls of the base 11. The mounting plate 111 is located at the bottom of the upper side panel of the mounting frame 14. The drive device 113 is mounted on the top of the upper side panel of the mounting frame 14, and the drive end of the drive device 113 is fixed to the top of the mounting plate 111. Thus, the mounting plate 111 can be driven to move linearly up and down by the drive device 113.

[0037] like Figure 3 and Figure 5 As shown, the upper mold 15 is installed at the bottom of the mounting plate 111, the second screw 112 is installed between the upper mold 15 and the mounting plate 111, and the guide rod 114 is installed through the top wall of the mounting frame 14, with the lower end of the guide rod 114 fixed to the top of the mounting plate 111. When the driving device 113 drives the mounting plate 111 to move, the mounting plate 111 drives the upper mold 15 to move linearly up and down to open the plate. At the same time, in order to ensure the linear movement of the mounting plate 111, a pair of guide rods 114 slide along with the mounting plate 111 on the mounting frame 14 to ensure the linear movement of the upper mold 15. The fixing of the second screw 112 makes it easy to disassemble and assemble the upper mold 15, thus making it easy to replace the upper mold 15.

[0038] like Figure 2 and Figure 7As shown, a pair of limiting plates 21 are arranged horizontally on the front and rear sides of the base 11. The opposite side of the pair of limiting plates 21 is set as a downward inclined wedge-shaped surface, so that the pair of limiting plates 21 clamp the front and rear ends of the plate through the wedge-shaped surface, reducing the contact area between the limiting plates 21 and the plate. This allows the plate to be moved between the pair of limiting plates 21 after the plate is drilled without loosening the limiting plates 21, while limiting the plate. This facilitates the replacement of the drilling position of the plate and improves the drilling efficiency of the plate.

[0039] like Figure 1 and Figure 7 As shown, the adjustment assembly includes a slide rail 22, a bidirectional lead screw 23, and a slider 24. The slide rail 22 is provided in pairs and is opened at the left and right ends of the base 11 in a front-back manner. The slider 24 is slidably connected in the slide rail 22, and each slide rail 22 is provided with a pair of sliders 24.

[0040] like Figure 1 and Figure 7 As shown, a bidirectional lead screw 23 is rotatably connected inside the slide rail 22. A pair of sliders 24, installed inside the slide rail 22, are threaded onto the positive and negative threads of the bidirectional lead screw 23, respectively. The upper ends of the pair of sliders 24 are fixed to the bottom of a pair of limiting plates 21. One end of the bidirectional lead screw 23 is placed on the outside of the base 11 and is equipped with a handwheel. By rotating the bidirectional lead screw 23 with the handwheel, the bidirectional lead screw 23 can drive the pair of limiting plates 21 to move closer to or further away from each other through the sliders 24, thereby achieving clamping and limiting of the front and rear sides of the plate.

[0041] In use, the lower die 13 and upper die 15 are replaced according to the required opening size of the metal sheet. When replacing the lower die 13, it is mounted on the base 11 via the first mounting component; when replacing the upper die 15, it is mounted on the base 11 via the second mounting component. This allows the upper die 15 to be used to open holes in the sheet metal placed on the lower die 13, enabling different hole openings. This facilitates the replacement of the lower die 13 and upper die 15 with the corresponding hole diameter. The first and second mounting components make the replacement of the lower die 13 and upper die 15 convenient, improving the practicality of the stamping die. When opening holes in the sheet metal, the sheet metal is placed between a pair of limiting plates 21. The spacing between the pair of limiting plates 21 is adjusted by the adjusting component, allowing the pair of limiting plates 21 to clamp and position the front and rear sides of the sheet metal, thereby restricting the movement of the sheet metal and ensuring that the sheet metal does not shift when the upper die 15 opens holes in the sheet metal, improving the accuracy of the hole opening.
