[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figure 1-6 , the present invention provides a technical solution: a hardware fitting processing die, including a lower die 3 and an upper die 2 erected on the top of the lower die 3. Die core installation grooves 9 are provided inside the upper die 2 and the lower die 3. A lower fixing plate 4 is installed at the bottom of the lower die 3, and an upper fixing plate 1 is installed at the top of the upper die 2; a guide rail 12 is installed on one side of the lower fixing plate 4. A bidirectional threaded rod 13 is rotatably installed inside the guide rail 12. Gears 14 are installed between both ends of the bidirectional threaded rod 13 and the guide rail 12. A saw tooth bar 11 is installed on one side of the bottom of the upper fixing plate 1, and the bottom of the saw tooth bar 11 extends to the guide rail 12 and meshes with the gear 14. Symmetrical slide seats 16 are rotatably installed on the periphery of the bidirectional threaded rod 13. A U-shaped frame 17 is connected to the top of the slide seat 16. A chute 18 is provided inside the U-shaped frame 17. A clamping table 19 is slidably installed inside the chute 18. A lead screw 20 penetrating the U-shaped frame 17 is installed at one end of the clamping table 19 away from each other. A nut 21 is rotatably installed on the periphery of the lead screw 20.

[0026] Based on the above structure settings, this metal hardware processing die is composed of an upper fixing plate 1, an upper die 2, a lower die 3, a lower fixing plate 4, and a die core installation groove 9. Among them, the upper fixing plate 1 and the lower fixing plate 4 are used for connection with external structures. The upper die 2 and the lower die 3 cooperate with each other to achieve stamping processing of metal hardware. The die core installation groove 9 is used for assembling the die core required for metal hardware. Specifically, before processing, the positions of the two clamping platforms 19 inside the sliding groove 18 are manually adjusted according to the size of the workpiece to be processed. After adjustment, the position of the lead screw 20 inside the sliding groove 18 is limited by rotating the nut 21. At this time, the positions of the two clamping platforms 19 on the return frame 17 are symmetrical to each other. After the upper fixing plate 1 and the lower fixing plate 4 are connected to the external structure, the upper fixing plate 1 moves upward under the drive of the external structure, separating the upper die 2 from the lower die 3. During the upward movement of the upper fixing plate 1, the saw tooth rack 11 also moves upward. During the movement of the saw tooth rack 11, the gear 14 is driven to rotate by the tooth platform. The bidirectional threaded rod 13 drives the slide block 16 to approach the gear 14 simultaneously under the drive of the gear 14. During the movement of the slide block 16, the return frame 17 is driven to move simultaneously, expanding the gap between the clamping platforms 19. After placing the workpiece to be processed between the upper die 2 and the lower die 3, the upper fixing plate 1 drives the upper die 2 and the saw tooth rack 11 to move downward. During the downward movement of the saw tooth rack 11, the return frame 17 is driven to reset by the bidirectional threaded rod 13. During the reset process of the return frame 17, the clamping platforms 19 drive to clamp the workpiece, improving the accuracy of workpiece processing. This metal hardware processing die, by installing the clamping platforms 19, can adjust the positions of the clamping platforms 19 under the drive of the upper fixing plate 1 during use, so as to clamp the position of the workpiece before stamping. By adjusting the positions of the clamping platforms 19 inside the sliding groove 18, workpieces of different sizes can be clamped during use.

[0027] Furthermore, a connection seat 5 is installed on the top of the upper fixing plate 1, and connection holes 6 are circumferentially formed around the periphery of the connection seat 5. Among them, an inner groove is formed on the top of the connection seat 5. Specifically, an external power structure is inserted into the inner groove on the top of the connection seat 5. After insertion, the connection seat 5 is connected to the external power structure by bolts passing through the connection holes 6, thereby achieving assembly.

[0028] Furthermore, sleeves 7 are installed at the four corners of the bottom of the upper fixing plate 1, and guide rods 8 are installed at the four corners of the top of the lower fixing plate 4, and the positions of the guide rods 8 and the sleeves 7 correspond one by one. Among them, an inner groove is formed inside the sleeve 7. Specifically, the guide rods 8 and the sleeves 7 can guide the movement trajectories of the upper fixing plate 1 and the lower fixing plate 4 during use, increasing the precision of metal hardware processing.

[0029] Further, a blanking hole 10 is formed in the bottom of the lower fixing plate 4, and the blanking hole 10 corresponds to the position of the die core installation groove 9. Among them, the blanking hole 10 is located at the center of the die core installation groove 9; specifically, through the blanking hole 10, the waste generated inside the die core installation groove 9 can be discharged during use, so as to facilitate the user to centrally clean the waste.

[0030] Further, bearings 15 are installed inside the guide rails 12 at both ends of the gear 14, and a shaft rod extending into the inside of the bearing 15 is installed at one end of the gear 14 away from the bidirectional threaded rod 13. Among them, the shaft rod is connected to the inner ring of the bearing 15, and the outer ring of the bearing 15 is connected to the guide rail 12; specifically, by using the bearing 15, while being able to limit the positions of the bidirectional threaded rod 13 and the gear 14 inside the guide rail 12 during use, it will not affect the rotation of the bidirectional threaded rod 13 and the gear 14.

[0031] Further, positioning platforms 22 are connected to both ends of the lower fixing plate 4, and positioning bolts 23 are slidably installed inside the positioning platforms 22. Among them, the positioning platforms 22 are fixedly connected to the lower fixing plate 4; specifically, through the positioning platforms 22, the contact area between the bottom of the lower fixing plate 4 and the external structure can be enlarged, and after the positioning bolts 23 pass through the positioning platforms 22 and are connected to the external structure, the position of the lower fixing plate 4 becomes more stable.

Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.
