[0024] like Figure 1-4 As shown, an electric stamping tool with automatic unloading includes a workbench 1 and a punch arm 2 slidably arranged on one side of the workbench 1, the punch arm 2 is an inverted L-shape, a punch 3 is fixedly provided at the bottom of the punch arm 2, and a driving mechanism for driving the punch 3 to move up and down is provided on the punch arm 2, the punch 3 includes a main punch 4 and a guide limit shaft 5, the main punch 4 is fixed at the bottom of the guide limit shaft 5, a punch sleeve 6 is provided on the workbench 1 below the main punch 4, an aluminum plate is placed on the workbench 1, and the driving mechanism drives the punch 3 to move downward, and the main punch 4 and the punch sleeve 6 cooperate to stamp the aluminum sheet.

[0025] In this embodiment, the punching arm 2 includes a vertical arm and a horizontal arm, and a driving mechanism is arranged on the horizontal arm, and the driving mechanism can be a driving cylinder.

[0026] In this embodiment, the outer sleeve of the guide limit shaft 5 is provided with a compression spring 7, and a guide sleeve 8 is slidably provided on the outside of the guide limit shaft 5 below the compression spring 7. One end of the compression spring 7 is fixedly connected to the top of the guide sleeve 8, and the other end is fixedly connected to the outer wall of the guide limit shaft 5. A top sleeve 9 is fixedly provided on the outside of the guide sleeve 8. The bottom wall of the top sleeve 9 is located below the main punch 4, and a first through hole 10 is provided at the bottom of the top sleeve 9 corresponding to the main punch 4. When the guide limit shaft 5 and the main punch 4 move downward, the bottom of the top sleeve 9 first abuts against the aluminum plate, and then the main punch 4 and the guide limit shaft 5 continue to move downward to punch out the circular aluminum sheet. At the same time, the compression spring 7 is compressed. After the stamping is completed, the guide limit shaft 5 and the main punch 4 move upward. Under the action of the rebound force of the compression spring 7, the top sleeve 9 pushes out the aluminum plate hanging on the main punch 4 for unloading.

[0027] In this embodiment, the punch sleeve 6 includes a stamping portion 11 and a blanking portion 12. A second through hole is provided in the middle portion of the stamping portion 11. The second through hole includes a cylindrical stamping hole 13 and a truncated cone-shaped blanking hole 14. The bottom diameter of the blanking hole 14 is greater than the top diameter. The blanking hole 14 is connected to the blanking portion 12. The diameter of the stamping hole 13 is greater than the diameter of the main punch 4. The diameter of the first through hole 10 is greater than the diameter of the stamping hole 13.

[0028] In this embodiment, a feed port 15 is provided on the workbench 1 below the punch sleeve 6, and a collecting box 16 is provided at the bottom of the workbench 1. The feed port 15 is connected to the collecting box 16, and the punched round aluminum sheet enters the feed port 15 through the feed hole 14 and the feed portion 12, and then enters the collecting box 16.

[0029] In this embodiment, a positioning sleeve 17 is provided on the workbench 1, and a positioning shaft 18 is provided at the bottom of the punch 3. Before stamping, the positioning shaft 18 and the positioning sleeve 17 are connected by moving the punch arm 2 to ensure the position accuracy between the main punch 4 and the punch sleeve 6, thereby ensuring the stamping accuracy and the quality of the stamped circular aluminum sheet.

[0030] Preferably, the inner bottom wall of the collection box 16 is set as a slope, and a shock-absorbing layer is provided inside the collection box 16. The shock-absorbing layer is made of shock-absorbing material. The shock-absorbing layer can cushion the falling round aluminum sheets to prevent the round aluminum sheets from being damaged and affecting the product quality. The inner bottom wall of the collection box 16 is set as a slope, and the round aluminum sheets falling into the collection box 16 move downward under the action of the slope, preventing the round aluminum sheets falling into the collection box 16 from stacking together.

[0031] When this embodiment is in use, the positioning sleeve 17 and the positioning shaft 18 are connected by moving the punch arm 2 to ensure the position accuracy between the main punch 4 and the punch sleeve 6, and then the aluminum plate is placed on the workbench 1, and the driving mechanism is started to drive the main punch 4 and the guide limit shaft 5 to move downward. When the bottom of the top sleeve 9 is against the workbench 1, the main punch 4 and the guide limit shaft 5 continue to move downward, and the compression spring 7 is compressed. When the main punch 4 enters the cylindrical punching hole 13, the round aluminum sheet is punched out of the discharge hole 14, and then passes through the discharge part 12 and the discharge port 15 into the collecting box 16. After the stamping is completed, the driving mechanism drives the main punch 4 and the guide limit shaft 5 to move upward, and the compression spring 7 rebounds. Under the action of the rebound force of the compression spring 7, the top sleeve 9 pushes out and discharges the aluminum plate hanging on the main punch 4.

[0032] The utility model uses the function of the ejector sleeve and the compression spring to eject the aluminum plate hung on the main punch and unload the material, and does not need manual unloading, so the use is more convenient and the efficiency is higher.

[0033] The specific implementation methods of the utility model described above do not constitute a limitation on the protection scope of the utility model. Any other corresponding changes and modifications made according to the technical concept of the utility model should be included in the protection scope of the claims of the utility model.
