Technical Field
[0001] This utility model belongs to the field of stamping dies, and specifically relates to a stamping die unloading plate. Background Technology
[0002] The stripper plate in a stamping die is an important component used to remove the stamped workpiece from the die. Its main function is to push the formed workpiece out of the die and prevent the workpiece from getting stuck inside the die.
[0003] When existing stamping dies are used to process metal raw material plates, the stripper plate of the stamping die usually uses a spring structure to push the stamped metal parts outward. However, when a single spring structure pushes out the metal parts, the spring rebound force cannot be concentrated due to the lack of a limiting structure. As a result, it is difficult to evenly feed the rebound force back to the stripper plate, making it difficult to remove the metal parts completely from the die. Furthermore, since existing stripper plates are often integrally formed, they inevitably rub against the die itself or the stamped parts after long-term use, causing them to wear down. The integral mounting structure often makes it difficult to quickly replace the stripper plate when it malfunctions.
[0004] Therefore, to address the problem that the fixed stripper plate structure of the aforementioned stamping die is difficult to quickly replace or maintain as needed, and that the service life of the stripper plate is relatively limited, a stamping die stripper plate has been developed. By adding a spring structure, a limit rebound structure, a stamping limit structure, and a quick splicing structure to the stamping die device, the demolding effect of the device during the stamping of metal raw material plates can be effectively improved, and the convenience of disassembling and replacing the die stripper plate can be enhanced. Utility Model Content

The frame assembly is equipped with a stamping die assembly, and the die assembly is equipped with the unloading plate body 2. A third groove 15 is formed through the upper and lower ends of an extension frame 13, and the bearing 14 is installed in the third groove 15. A symmetrical connecting frame 20 is fixed to one end of the extension frame 13. A second threaded groove 21 is formed through the upper and lower ends of the connecting frame 20. Two sets of symmetrical fourth grooves 19 are formed at the lower end of the unloading plate body 2, and the connecting frame 20 is installed in the fourth groove 19. A bolt 22 passes through a first threaded groove 18 and is installed in the second threaded groove 21. The bolt 22 can be inserted into the second threaded groove 21 when needed. The stripper plate body 2 is removed from the groove 18 and the second screw groove 21. Then, the worker manually moves the stripper plate body 2 downward from the connecting frame 20 on the left and right extension frames 13. This allows for quick replacement of the stripper plate body 2 if it is damaged or malfunctions. The extension frames 13 are divided into left and right sides. The stripper plate body 2 has a stripper groove 17 through the center of the upper and lower ends. A spring body 16 is fixed to the lower edge of the extension frame 13. In use, the spring body 16 cooperates with the stripper plate body 2 to push the stamped metal parts upward after the upper mold 1 and lower mold 3 have stamped the metal raw material plate. The extension frame 13 and bearing 14 can provide limiting assistance for the stripper plate body 2 when it moves up and down, and reduce the friction of the stripper plate body 2 when pushing out the stamped parts, thereby improving its service life.
[0026] Please see Figure 3 In this embodiment, the frame assembly includes a base plate 4, limiting posts 5, and a top frame 6. The limiting posts 5 are fixed to the four corner edges of the upper end of the base plate 4, and the top frame 6 is installed on the upper end of the limiting posts 5. In use, the limiting posts 5 can provide limiting assistance to the four corner edges of the upper mold 3 to improve the stability of the upper mold 3 in stamping the lower mold 1. Hydraulic grooves 10 are provided through the upper and lower ends of the top frame 6. The outer wall of the limiting posts 5 is provided with six sets of rolling grooves 7 that are equidistantly distributed around the limiting posts 5. In use, the hydraulic grooves 10 can facilitate the stamping machine to drive the upper mold 3 to stamp the metal raw material plate on the lower mold 1.
[0027] Please see Figures 3-5In this embodiment, the inner wall of the through hole 12 is fitted with the outer wall of the limiting post 5, the lower end of the spring body 16 is installed in the spring groove 8, the inner wall of the bearing 14 is fitted with the outer wall of the limiting post 5, and the balls on the inner wall of the bearing 14 are adapted to the rolling groove 7. In use, the bearing 14, in conjunction with the rolling groove 7 and the limiting post 5, can provide double limiting assistance for the unloading plate body 2 to improve the stability of the metal parts after the unloading plate body 2 is ejected from the stamping.

[0028] When working, first, the lower end of the press telescopic rod is passed through the hydraulic groove 10 and installed on the upper end of the upper mold 3, and the metal raw material plate is placed on the upper end of the unloading plate body 2.
[0029] Next, the stamping machine is started, and the stamping machine drives the upper mold 3 to press downward along the outer wall of the limiting post 5, so as to push the bearing 14 on the unloading plate body 2 to compress the spring body 16 along the roller groove 7, and make the unloading plate body 2 move down into the second groove 11 on the lower mold 1, thereby stamping the metal raw material plate onto the lower mold 1 to complete the stamping process.
[0030] Then, the press drives the upper mold 3 to reset, and the compressed spring body 16 pushes the unloading plate body 2 and the metal parts on it to be removed upwards, so as to remove the stamped metal parts from the lower mold 1.
[0031] When it is necessary to replace the damaged unloading plate body 2, the embedded bolt 22 is removed from the first screw groove 18 and the second screw groove 21 by tightening the bolt 22. Then, the unloading plate body 2 is held by hand and removed from the two connecting frames 20. The fourth groove 19 on the new unloading plate body 2 is then aligned with the connecting frame 20, and the new unloading plate body 2 is installed on the two extension frames 13. The new unloading plate body 2 is then installed on the two extension frames 13 by passing the bolt 22 through the first screw groove 18 and the second screw groove 21.
[0032] Through the above steps, the embedded bolts 22 can be used to remove the material from the first screw groove 18 and the second screw groove 21 when needed. Then, the worker can manually move the main body of the unloading plate 2 downward from the connecting frame 20 on the left and right extension frames 13. This allows for quick replacement of the main body of the unloading plate 2 when it is damaged or malfunctions. This solves the problem that the fixed unloading plate structure of the stamping die is difficult to replace or maintain quickly as needed during use.
