[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] The present utility model provides a technical solution: a metal shrapnel stamping die, specifically as follows:

[0028] It can be referred to Figures 1 to 4 , in order to facilitate the replacement of the stamping shape of the device according to requirements, a female die 6 is fixedly connected to the top of the slide block 5;

[0029] Among them, an adjustment groove 4 is opened at the top of the lower template 1, and the inner wall of the adjustment groove 4 is slidably connected with a slide block 5. Therefore, the slide block 5 can be adjusted to a suitable position in the adjustment groove 4 according to requirements. Therefore, the female die 6 can be replaced very conveniently, and different female dies 6 can be adjusted according to requirements. Both sides of the outer surface of the female die 6 are threadedly connected with fixed bolts 7, and one end of the fixed bolt 7 passing through the female die 6 abuts against the top of the lower template 1, which can fix the adjusted female die 6, thereby ensuring the installation stability of the female die 6 during the stamping process;

[0030] It can be referred to Figures 1 to 4 , in order to timely discharge the formed metal shrapnel outwards, a discharge groove 8 is opened in the middle of the top of the lower template 1;

[0031] Among them, the discharging groove 8 can convey the metal shrapnel falling from the female die 6. The inner wall of the discharging groove 8 is inclined, so that when the metal shrapnel falls, it directly slides outwards, thus sliding out of the lower template 1, which is convenient for the staff to collect the metal shrapnel;

[0032] for reference, see Figures 1 to 4 , in order to assist the sliding of the upper template 3, guide rods 2 are fixedly connected to the four corners of the top of the lower template 1;

[0033] Among them, guide holes 18 are provided at the four corners of the top of the upper template 3. The inner wall of the guide hole 18 is slidably connected to the outer surface of the guide rod 2. Therefore, the relative sliding between the guide hole 18 and the guide rod 2 can be used to assist the sliding of the upper template 3 and ensure the accurate matching between the female die 6 and the male die 9;

[0034] for reference, see Figures 1 to 4 , in order to press and fix the metal plate, a pressing plate 12 is fixedly connected to the bottom of the adjusting rod 10;

[0035] Among them, an adjusting rod 10 is slidably connected below the upper template 3, so that the pressing plate 12 can be driven to float up and down below the upper template 3. The distance between the pressing plate 12 and the upper template 3 is greater than the length of the male die 9. Therefore, the pressing plate 12 first contacts the stamping raw material, and then the male die 9 stamps the raw material into shape. A compression spring 11 is sleeved on the outer surface of the adjusting rod 10. The top end of the compression spring 11 is fixedly connected to the bottom of the upper template 3, and the bottom end of the compression spring 11 is fixedly connected to the top of the pressing plate 12. Through the setting of the compression spring 11, after the adjusting rod 10 drives the pressing plate 12 to press the metal plate, the adjusting rod 10 will slide below the upper template 3, thereby compressing the compression spring 11. Therefore, the elastic force of the compression spring 11 can be used to press the pressing plate 12 downwards to ensure the pressing stability of the pressing plate 12 on the metal plate. After the upper template 3 returns upwards, under the pushing of the elastic force of the compression spring 11, the pressing plate 12 can be pressed until the male die 9 is separated from the metal plate, and then the pressing plate 12 is separated from the metal plate. A jack 13 adapted to the male die 9 is provided on the top of the pressing plate 12. The inner wall of the jack 13 is slidably connected to the outer surface of the male die 9. The jack 13 enables the male die 9 to pass through it, and the male die 9 and the pressing plate 12 slide relative to each other, and then the male die 9 stamps the metal plate into shape;

[0036] for reference, see Figures 1 to 4 , in order to stamp the metal plate into shape, a forming groove 14 adapted to the male die 9 is provided on the top of the female die 6;

[0037] Among them, the inner wall of the forming groove 14 is in communication with the inner wall of the discharge groove 8. Thus, during the downward movement of the punch 9, the punch 9 can be inserted into the forming groove 14 to stamp the metal sheet, and then the formed metal elastic sheet is pressed into the discharge groove 8.

[0038] Refer to Figures 1 to 4 , in order to increase the pressing stability of the pressing plate 12 on the metal sheet, clamping grooves 15 are provided at the four corners of the bottom of the pressing plate 12, and gaskets 16 are fixedly connected to the inner side walls of the four clamping grooves 15.

[0039] Among them, during the downward pressing of the pressing plate 12, the gasket 16 can first contact the metal sheet to increase the sliding difficulty of the metal sheet. Then, the pressing plate 12 fully presses and fixes the metal sheet. An anti-slip pad 17 is fixedly connected between the jacks 13 at the bottom of the pressing plate 12. Thus, the metal sheet is pressed and fixed near the forming groove 14 to further reduce the deformation of the metal sheet when the punch 9 stamps the metal sheet.

[0040] In the present utility model, the working steps of the device are as follows:

[0041] First, adjust the slider 5 through the adjustment groove 4 to adjust the female die 6 to a suitable position, and then tighten the fixing bolt 7 to ensure the installation stability of the female die 6. Then, the staff can place the metal sheet between the punch 9 and the female die 6, and then press down the upper template 3, so that the pressing plate 12 first presses and fixes the metal sheet. After the pressing is completed, make the gasket 16 and the anti-slip pad 17 fully contact the metal sheet. Then, extend the punch 9 from the jack 13, and stamp the metal sheet with the forming groove 14 and the punch 9. The formed metal elastic sheet is pushed out of the forming groove 14 and sent into the discharge groove 8, and then the discharge groove 8 sends the metal elastic sheet outwards, and the staff can collect the metal elastic sheet.

[0042] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
