Abstract
Description
Technical Field
[0001] This utility model relates to the field of stamping die technology, specifically to a stamping die for an aluminum drawing pan. Background Technology
[0002] Aluminum drawn cookers are mainly manufactured using a metal drawing process. This involves cutting aluminum sheets into flat sheets using a machine. Before drawing, the sheets are flattened and oiled to make them easier to shape during drawing. The aluminum sheets are then placed in a mold, and the powerful pressure of the drawing machine is used to press and draw the aluminum sheets into the desired cooker shape, such as a cylinder. However, most traditional stamping molds do not have a demolding mechanism. After the aluminum drawn cooker is drawn, it adheres tightly to the mold, making it difficult to remove. Operators usually need to manually tap or pry it with tools, which affects work efficiency and can easily cause scratches and deformation damage to the surface of the drawn cooker. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Please see Figures 1 to 6This utility model provides a technical solution: a stamping die for an aluminum stretching pan, comprising: a bottom support base 1; guide pillars 2 symmetrically fixed to the top of the bottom support base 1; a sliding seat 4 slidably disposed on the outside of the guide pillars 2; a limiting guide sleeve 6 equidistantly fixed to the bottom of the sliding seat 4, a limiting guide rod 24 slidably disposed inside the limiting guide sleeve 6, a limiting plate fixed inside the limiting guide rod 24, and the limiting plate slidably connected to the limiting guide sleeve 6; an upper stamping die 7 fixedly disposed at the bottom end of the limiting guide rod 24; and a support sleeve 11 passing through... Bolts are installed on the top of the bottom support 1; the sliding sleeve 12 is slidably disposed inside the support sleeve 11, and the inner fixing box 16 is installed inside the sliding sleeve 12 by bolts; the limiting baffle 17 is slidably disposed inside the inner fixing box 16; the tension top seat 13 is fixedly connected to the inside of the support sleeve 11, and the tension top seat 13 is located inside the sliding sleeve 12; the ejector pin 15 is equidistantly slidably disposed inside the tension top seat 13, the ejector pin 15 is slidably connected to the support sleeve 11, and the ejector pin 15 is slidably connected to the bottom support 1.
[0030] It should be noted that in this embodiment, the processed aluminum sheet is placed on the sliding sleeve 12, and the position of the sheet is restricted by the limiting baffle 17. The output end of the first cylinder 5 drives the sliding seat 4 to move downward. The sliding seat 4 slides and is limited outside the guide pillar 2. The sliding seat 4 drives the limiting guide sleeve 6, the limiting guide rod 24, the limiting slide rod 8, and the first return spring 9 to move downward as a whole. The stamping die 7 presses the metal sheet and the sliding sleeve 12. The stamping die 7 moves upward under pressure. The stamping die 7 drives the limiting guide rod 24 to slide inside the limiting guide sleeve 6. The stamping die 7 drives the limiting slide rod 8 to slide with the sliding seat 4. The stamping die 7 presses the first return spring 9 to moderate the movement of the stamping die 7. The stamping die 7 moves to the limiting guide sleeve. After the bottom of 6 stops moving, the upper stamping die 7 presses the metal sheet and the sliding sleeve 12 downwards. The sliding sleeve 12 presses the third return spring 21. The aluminum alloy sheet is stretched and formed by the cooperation of the stretching top seat 13 and the upper stamping die 7. The sliding sleeve 12 drives the fixed slide plate 19 to slide and limit the outside of the second limit rod 20. After the forming is completed, the output end of the first cylinder 5 drives the sliding seat 4 and the upper stamping die 7 to move upwards. At the same time, the output end of the second cylinder 14 drives the inner sliding plate 23 and the ejector pin 15 to move upwards. The ejector pin 15 assists in the ejection of the aluminum pot on the stretching top seat 13. The third return spring 21 resets the sliding sleeve 12 upwards, making it easy to remove the stretched aluminum pot.
[0031] In one embodiment, such as Figure 4 and Figure 5As shown, multiple fixed slide plates 19 are fixedly connected at equal intervals on the outer side of the sliding sleeve 12. The fixed slide plates 19 are slidably connected to the support sleeve 11. A second limiting rod 20 is symmetrically slidably arranged inside the fixed slide plate 19. The second limiting rod 20 is fixedly connected to the support sleeve 11. A multiple third return springs 21 are symmetrically arranged inside the support sleeve 11.
[0032] It should be noted that, in this embodiment, when the sliding sleeve 12 slides within the support sleeve 11, the sliding sleeve 12 drives the outer fixed slide plate 19 to slide and be limited outside the second limiting rod 20, thereby improving the movement stability of the sliding sleeve 12.
[0033] In one embodiment, such as Figures 1 to 5 As shown, a bottom fixing box 22 is fixedly connected to the bottom of the bottom support 1, and the ejector pin 15 is slidably connected to the bottom fixing box 22. An inner sliding plate 23 is slidably arranged inside the bottom fixing box 22, and the bottom end of the ejector pin 15 is fixedly connected to the inner sliding plate 23.
[0034] It should be noted that in this embodiment, the inner sliding plate 23 slides within the bottom fixed box 22, and the inner sliding plate 23 drives the ejector pin 15 to move. The ejector pin 15 assists in stretching the aluminum pot formed on the top seat 13 to eject it, which facilitates demolding.
[0035] In one embodiment, such as Figures 1 to 5 As shown, a first limiting rod 10 is symmetrically slidably arranged inside the inner sliding plate 23. The first limiting rod 10 is fixedly connected to the bottom fixed box 22. A second cylinder 14 is symmetrically installed on the top of the bottom support seat 1. The output end of the second cylinder 14 is fixedly connected to the inner sliding plate 23.
[0036] It should be noted that in this embodiment, the output end of the second cylinder 14 drives the inner sliding plate 23 to slide within the bottom fixed box 22. The inner sliding plate 23 slides to a limit outside the first limit rod 10, thereby improving the movement stability of the inner sliding plate 23 and the ejector pin 15.
[0037] In one embodiment, such as Figure 1 , Figure 2 and Figure 6 As shown, a fixed support plate 3 is fixedly connected to the top of the guide support 2, and a cylinder 5 is installed on the top of the fixed support plate 3. The output end of the cylinder 5 is fixedly connected to the sliding seat 4. Multiple limiting slide rods 8 are fixedly connected at equal intervals to the top of the stamping upper die 7. The limiting slide rods 8 are slidably connected to the sliding seat 4, and a return spring 9 is sleeved on the outside of the limiting slide rods 8.
[0038] It should be noted that in this embodiment, the upper stamping die 7 is limited, supported, and guided by the limiting guide sleeve 6, the limiting guide rod 24, and the limiting plate, and the movement of the upper stamping die 7 is buffered by the first reset spring 9.
[0039] In one embodiment, such as Figure 5 As shown, multiple No. 2 return springs 18 are equidistantly arranged inside the inner fixed box 16.
[0040] It should be noted that in this embodiment, the moving position of the limiting baffle 17 is reset by the second reset spring 18.
