In addition, the lower die is designed to be detachable, allowing for easy switching between different models of die slots.

[0008] As a further improvement of this application, a bottom shaft is fixedly connected to the top of the stamping table on the side away from the first screw, and a rotating shaft extending into the body of the stamping equipment is rotatably connected to the middle of the bottom shaft.

[0009] As a further improvement of this application, a connecting shaft is fixedly connected to the top of the rotating shaft, and an electromagnetic block is fixedly connected to the end of the connecting shaft away from the rotating shaft, and the electromagnetic block engages with the gasket.

[0010] As a further improvement of this application, a servo motor is installed inside the stamping equipment body, and the output end of the servo motor is connected to the rotating shaft.

[0011] As another improvement of this application, a hopper connected to the side end of the stamping table is installed above the end of the stamping equipment body away from the limit plate, and a receiving box is placed on the side of the stamping equipment body directly below the hopper.

[0012] As a further improvement to this application, the stamping equipment body has a discharge port at the end away from the receiving box, and the lower die is connected to the die groove, with a recycling box located directly below the die groove placed in the discharge port.

[0013] As a further improvement to this application, a controller for controlling the hydraulic cylinder, the electromagnetic block, and the servo motor is fixedly connected to the body of the stamping equipment.

[0014] In summary, the lower die is inserted into the corresponding slot from the side of the stamping table, thus securing the lower die into the stamping table. Then, the limiting plate is inserted into the side of the stamping table and fixed with the first screw, thus positioning the lower die. Next, a shim is inserted into the die slot to fit against its inner wall, and a pin is inserted into the corresponding screw hole. The retaining plate is then secured to the top section of the shim. Finally, a second screw is inserted into the pin and tightened to fix it to the screw hole, thus positioning the retaining plate on the pin and achieving the positioning of the shim. The nut material is then placed in the shim within the die slot. The controller activates the hydraulic cylinder to drive the upper die to stamp the nut. When the die slot wears severely after long-term high-frequency use, it can be replaced promptly. Attached Figure Description

[0024] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0025] First implementation method:

[0026] Figures 1-5 A metal parts stamping device is shown, including a stamping device body 1. A hydraulic cylinder 9 is fixedly connected to the top of the stamping device body 1. An upper mold is installed at the output end of the hydraulic cylinder 9 via a movable shaft. A stamping table 5 is fixedly connected to the stamping device body 1 directly below the upper mold. The inner wall of the stamping table 5 is symmetrically provided with slots 22. A lower mold 8 is slidably connected to the slots 22 via a locking block 14. A limiting plate 6 is detachably connected to the side of the stamping table 5, and the limiting plate 6 is threadedly connected to the stamping table 5 via a first screw 7. A mold groove 13 is provided at the top of the lower mold 8. A gasket 15 is detachably connected to the mold groove 13. A plurality of screw holes 16 are equidistantly provided at the top of the lower mold 8 on the side of the mold groove 13. A pin 17 is inserted into the screw hole 16, and the pin 17 is threadedly connected to the screw hole 16 via a second screw 18. A locking plate 19 is fixedly connected above the side wall of the pin 17, and the locking plate 19 abuts against the top section of the gasket 15.

[0027] A controller consisting of a control cylinder 9, an electromagnetic block 12, and a servo motor 21 is fixedly connected to the main body 1 of the stamping equipment.

[0028] Working principle: The lower mold 8 is inserted into the corresponding slot 22 by the locking block 14 from the side of the stamping table 5, thereby locking the lower mold 8 into the stamping table 5. Then, the limiting plate 6 is inserted into the side of the stamping table 5 and fixed to the stamping table 5 by the first screw 7, thereby installing and positioning the lower mold 8. At this time, the shim 15 is inserted into the mold groove 13 and fits against its inner wall, and the pin 17 is inserted into the corresponding screw hole 16. At this time, the locking plate 19 is locked on the top section of the shim 15. Then, the second screw 18 is inserted into the pin 17 and fixed to the screw hole 16 by screwing, thereby positioning the locking plate 19 on the pin 17 and achieving the positioning function of the shim 15. Then, the nut material is placed in the shim 15 in the mold groove 13. The controller opens the oil cylinder 9 to drive the upper mold to stamp and form the nut. When the mold groove 13 is severely worn after long-term high-frequency use, it can be replaced in time.

[0029] By setting the shim 15, wear on the inner wall assembly of the mold groove 13 can be avoided. When the shim 15 is severely worn, it can be easily disassembled and replaced by the clamping plate 19. At the same time, the lower mold 8 is designed to be detachable, and different models of mold groove 13 can be switched at will.

[0030] Second implementation method:

[0031] Figures 1-2 and Figures 6-7 A bottom shaft 20 is fixedly connected to the top of the stamping table 5 away from the first screw 7. A rotating shaft extending into the body of the stamping equipment 1 is rotatably connected to the middle of the bottom shaft 20. A connecting shaft 11 is fixedly connected to the top of the rotating shaft. An electromagnetic block 12 is fixedly connected to the end of the connecting shaft 11 away from the rotating shaft, and the electromagnetic block 12 engages with the gasket 15. A servo motor 21 is installed inside the body of the stamping equipment 1, and the output end of the servo motor 21 is connected to the rotating shaft. A hopper 10 connected to the side end of the stamping table 5 is installed above the end of the stamping equipment 1 away from the limit plate 6. A receiving box 4 is placed on the side of the stamping equipment 1 directly below the hopper 10. A discharge port 2 is opened on the end of the stamping equipment 1 away from the receiving box 4, and the lower mold 8 communicates with the mold groove 13. A recycling box 3 located directly below the mold groove 13 is placed in the discharge port 2.

[0032] Working principle: During the stamping of the nut, the waste generated can fall from the mold groove 13 into the recycling box 3 in the discharge port 2 for easy recycling. After stamping, the servo motor 21 can be turned on by the controller to drive the rotating shaft to rotate and move the electromagnetic block 12 on the connecting shaft 11. After the electromagnetic block 12 is moved to the position directly above the mold groove 13, the electromagnetic block 12 is turned on, which can attract the nut formed in the mold groove 13. After taking it out, it is rotated to the top of the discharge hopper 10 and then the electromagnetic block 12 is turned off. At this time, the nut automatically falls off and onto the discharge hopper 10 and then falls into the collection box 4 for collection.

[0033] By setting the electromagnetic block 12, the nut that has been formed in the mold groove 13 can be automatically removed.

[0034] In light of current practical needs, the above-described embodiments adopted in this application are not limited to this scope of protection. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
