[0021] Reference Figure 1-4 A detachable hardware terminal stamping die includes a base 1, which serves as the foundation of the entire die and provides stable support. Four sliding rods 2 are fixedly connected to the four opposite corners of the top of the base 1. These four sliding rods 2 are arranged vertically to ensure the stability of each part of the die during movement. The top of multiple sliding rods 2 is fixedly connected to the same top plate 3, which is horizontally positioned to provide a mounting base for the components above. A cylinder 4 is fixedly connected to the top of the top plate 3, and an output shaft 5 is fixedly connected to the output end of the cylinder 4. The output shaft 5 is driven by air pressure to reciprocate. The output shaft 5 passes through the top plate 3 and is fixedly connected to a stamping plate 6. The stamping plate 6 is slidably sleeved with the outer walls of the multiple sliding rods 2, ensuring that the vertical movement of the stamping plate 6 is unobstructed. The stamping plate 6 is connected to a stamping head 7 via a disassembly mechanism. A stamping die base 8 is fixedly connected to the top of the base 1, and the stamping die base 8 has stamping grooves corresponding to the stamping head 7.

[0022] The disassembly mechanism includes two pins 12 fixedly connected to the top of the stamping head 7. These two pins 12 are symmetrically arranged. Two symmetrically arranged connecting pins 10 are fixedly connected to the bottom of the stamping plate 6. The bottom of the two connecting pins 10 is fixedly connected to the same connecting block 11. The connecting block 11 has a slot 14 that matches the pin 12. The pin 12 is located in the slot 14. In order to achieve a more stable connection, a limiting groove 13 is opened on the pin 12. The connecting block 11 has two symmetrically arranged horizontal cavities 15. Horizontal rods 16 are slidably connected to the inner sidewalls of the horizontal cavities 15. The two horizontal rods 16 are located in the limiting groove 13, thereby playing a limiting role. The connecting block 11 has a vertical cavity 17. A vertical rod 18 is slidably connected to the inner sidewall of the vertical cavity 17. The vertical rod 18 is connected to the horizontal rod 16 through a driving mechanism. A disassembly plate 20 is fixedly connected to the top of the vertical rod 18. The connecting block 11 has a disassembly groove 19 that communicates with the vertical cavity 17. The disassembly plate 20 is located in the disassembly groove 19.

[0023] A return spring 21 is sleeved on the outer wall of the vertical rod 18. The two ends of the return spring 21 are fixedly connected to the bottom of the pull-out plate 20 and the bottom of the inner part of the disassembly groove 19, respectively, providing a stable reset mechanism so that when the stamping head 7 is disassembled and replaced, the pull-out plate 20 can quickly and accurately return to the initial position, thereby ensuring the efficient operation and precise alignment of the mold.

[0024] The driving mechanism includes a drag block fixedly connected to the outer wall of the horizontal bar 16 and the vertical bar 18. The drag block transmits power to the horizontal bar 16 and the vertical bar 18 through connection with an external driving device, thereby driving them to perform the required movement. The two drag blocks are connected by a drag rod 22, which connects the two drag blocks together so that they can move synchronously.

[0025] Both ends of the drag bar 22 are provided with drag ports, and the outer walls of the two drag blocks are fixedly connected with drag shafts. The inner walls of the drag ports are rotatably sleeved with the outer walls of the drag shafts.

[0026] A buffer spring 9 is fitted on the outer wall of the slide bar 2. The design of the buffer spring 9 needs to take into account the selection of materials and dimensions to adapt to stamping tasks of different intensities. The buffer spring 9 can be made of wear-resistant and highly elastic alloy steel wire to ensure that it can maintain good elasticity and stability after long-term use. The two ends of the buffer spring 9 are fixedly connected to the bottom of the stamping plate 6 and the top of the base 1, respectively.

[0027] The specific working principle of this utility model is as follows:

[0028] In the initial state, during actual operation, when this device is used, the operator first places the metal terminal to be stamped on the stamping die base 8 fixed on the top of the base 1. The stamping die base 8 has a pre-set stamping groove that matches the stamping head 7 to ensure that the workpiece can be accurately positioned and the force is even. Next, the cylinder 4 on the top plate 3 is activated, and the output end of the cylinder 4 pushes the output shaft 5 to move downward. The output shaft 5 is connected to the stamping plate 6. As the cylinder 4 pushes, the stamping plate 6 slides down along the slide rods 2 fixed at the four opposite corners of the base 1 to ensure that the whole process is stable and linear, avoiding the decrease in stamping accuracy caused by lateral swaying. The stamping head 7, which is connected to the bottom of the stamping plate 6 through the disassembly mechanism, moves down and gradually approaches the metal terminal located in the stamping die base 8. When the stamping head 7 reaches the predetermined position and contacts the metal terminal, sufficient pressure is applied to complete the stamping operation. At this time, the metal terminal is precisely processed into the required shape and size. After the stamping is completed, cylinder 4 reverses, and output shaft 5 drives stamping plate 6 and stamping head 7 back to the initial position, waiting for the next stamping task to be executed.

[0029] When it is necessary to remove the stamping head 7, the operator pulls the disassembly plate 20. The connecting block 11 has a disassembly groove 19 that communicates with the horizontal cavity 15. The disassembly plate 20 can move freely in the disassembly groove 19. The vertical rod 18 moves upward under the action of external force. The horizontal rod 16 is pulled out from the limiting groove 13 by the driving mechanism. At this time, the insert 12 separates from the slot 14, and the stamping head 7 can be taken out smoothly, thus realizing the quick disassembly and installation of the stamping head 7.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
