[0026] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1: Please refer to Figure 1-5 As shown, this utility model is a metal stamping die, including a housing 1. A sliding mechanism is fixedly installed in the middle of the upper end of the housing 1. The sliding mechanism is used to drive the stamping die to move up and down, so as to drive the metal plate to complete the stamping between the upper and lower dies. A U-shaped frame 2 is fixedly installed at the lower end of the sliding mechanism. A connecting rod 3 is fixedly installed at the lower end of the U-shaped frame 2. A U-shaped groove 4 is opened at the lower end of the connecting rod 3. A fixing plate 5 is sleeved in the groove of the U-shaped groove 4. A first bolt 6 is installed at the lower end of the connecting rod 3, passing through the U-shaped groove 4 and the fixing plate 5. The first bolt 6 enters from one side of the connecting rod 3 and passes through the U-shaped groove 4. The inner wall of the groove 4 and the interior of the fixing plate 5 extend out from the other side of the connecting rod 3. The upper mold 7 is fixedly installed at the lower end of the fixing plate 5. The upper mold 7 can be removed by loosening the first bolt 6, which facilitates the replacement of the severely worn upper mold 7. Inside the box 1, a stamping table 8 is fixed at the lower end of the upper mold 7. A lower mold groove 9 is opened at the upper end of the stamping table 8 directly below the upper mold 7. The lower mold groove 9 matches the upper mold 7 to complete the stamping of the metal plate. A lifting mechanism is fixed at the bottom of the box 1. The lifting mechanism is used to lift and jack up the mold after stamping, which facilitates the quick removal of the mold later.

[0028] The sliding mechanism includes a first cylinder 10 fixed to the upper end of the housing 1. A rectangular plate 11 is fixed to the end of the piston rod of the first cylinder 10. The lower end of the rectangular plate 11 is fixedly connected to the U-shaped frame 2. The rectangular plate 11 is used to make the up-and-down movement of the U-shaped frame 2 more synchronized when the first cylinder 10 moves up and down, thereby increasing its stability.

[0029] The lifting mechanism includes a second cylinder 12 fixed to the bottom of the housing 1. The piston rod of the second cylinder 12 passes through the bottom of the housing 1 and is fixedly connected to the bottom end of the lifting plate 13 inside the lower mold groove 9. Limiting blocks 14 are symmetrically fixedly installed at the bottom inside the lower mold groove 9. The limiting blocks 14 restrict the downward movement of the lifting plate 13. The upper end of the limiting block 14 contacts and connects with the lower end of the lifting plate 13. The second cylinder 12 drives the lifting plate 13 to move up and down slightly to lift the mold that completes the stamping.

[0030] The U-shaped frame 2 has a vertical rod 15 fixedly installed on one side of the connecting rod 3. The lower end of the vertical rod 15 is snapped with a cutting plate 16. The cutting plate 16 is detachable and replaceable and is used to cut the metal plate to be processed. A cutting groove 17 is opened at the upper end of the stamping table 8 directly below the cutting plate 16. The cutting groove 17 is used for the cutting plate 16 to move up and down in its groove to complete the cutting of the metal plate. The U-shaped frame 2 has a first spring 18 fixed on the other side of the connecting rod 3. A limit plate 19 is fixed at the lower end of the first spring 18. The limit plate 19 moves down to limit the position of the metal plate feeding. The cutting plate 16, the upper mold 7, and the limit plate 19 have different initial heights. During the downward movement of the U-shaped frame 2, the position is first fixed by the limit plate 19, then the cutting plate 16 completes the cutting of the metal plate, and finally the upper mold 7 and the lower mold groove 9 complete the stamping of the metal part.

[0031] One end of the stamping table 8 has a first through hole 20. Vertical plates 21 are symmetrically fixedly installed at both ends of the first through hole 20. Sliding blocks 22 are slidably disposed within the two vertical plates 21. The sliding blocks 22 can move up and down through grooves opened within the vertical plates 21. Second springs 23 are fixed to the two sliding blocks 22. Second bolts 24 are connected to the upper ends of the two second springs 23 by pins. Rotating the second bolts 24 can drive the second springs 23 downwards, increasing the friction between the roller and the metal plate. The sides of the two sliding blocks 22 are rotatably connected. The upper guide roller 25 is provided, and the bottom end of the vertical plate 21 is rotatably connected to the lower guide roller 26. A servo motor 27 is fixed on the outer side of the vertical plate 21. The output shaft end of the servo motor 27 is fixedly connected to the lower guide roller 26. The servo motor 27 drives the lower guide roller 26 to rotate, thereby driving the upper guide roller 25 to rotate, so as to complete the feeding. Multiple rubber pads 28 are fixedly provided on the roller shaft surfaces of the upper guide roller 25 and the lower guide roller 26. The rubber pads 28 are used to increase the friction between the stamping plate and the roller shaft, so as to facilitate better conveying of the metal plate.

[0032] In summary, the operator places the metal part to be stamped between the upper guide roller 25 and the lower guide roller 26, connects the external power supply, and starts the servo motor 27 to drive the two roller shafts to rotate. The rubber pads 28 fixed on the roller shafts increase the friction between the metal plate and the roller shafts. The pressure of the two roller shafts slowly conveys the metal plate forward. At this time, the first cylinder 10 drives the U-shaped frame 2 to move downward. The first spring 18 fixed at the lower end of the U-shaped frame 2 drives the limiting plate 19 to move downward. The limiting plate 19 contacts and fixes itself to the lower stamping table 8, thereby limiting the movement of the metal plate. Plate 19 is used to limit the movement of the metal plate to achieve precise stamping. After the metal plate is fixed in position, the U-shaped frame 2 is moved down and the metal part is cut by the cutting plate 16. After cutting, the metal part is stamped by the upper mold 7 and the lower mold groove 9. After the metal part is stamped, the lifting plate 13 at the bottom of the lower mold groove 9 is moved up by the second cylinder 12, thereby moving the metal part up and separating the metal part from the lower mold groove 9. This avoids the mold from being embedded in the lower mold groove 9 and difficult to remove, which is time-consuming, labor-intensive and reduces the production efficiency of the metal part stamping mold.

[0033] Example 2: Please refer to Figure 6 As shown, based on Embodiment 1, the other end of the stamping table 8 is provided with a sloping groove 29, and the lower end of the sloping groove 29 is fixed with a sloping plate 30. The sloping plate 30 and the box 1 form a storage space to collect the stamped metal parts. The metal parts slide slowly from the sloping groove 29 through the sloping plate 30 into the interior of the box 1. The side of the box 1 is provided with a second through hole 31, and a square plate 32 is connected to the second through hole 31 by a pin. The square plate 32 can be rotated and opened around the pin fixed to one side of the box 1 to facilitate the removal of the internal metal parts. A handle 33 is fixedly connected to the outside of the square plate 32.

[0034] A third cylinder 34 is fixed to one end of the housing 1. A suction cup electromagnet 35 is fixed to the end of the piston rod of the third cylinder 34. The suction cup electromagnet 35 can be a Deang DX2023 suction cup electromagnet 35. The suction cup electromagnet 35 is used to attract the stamped mold and drag it into the inclined groove 29.

[0035] The bottom of the housing 1 is fixed with a base 36, and the lower end of the base 36 is fixed with a shock-absorbing pad 37, which is used to prevent vibration from damaging the equipment itself.

[0036] In summary, after the metal part is lifted and stamped, the third cylinder 34, which is fixedly installed on the side of the housing 1, drives the suction cup electromagnet 35 to move and attract the stamped metal part. When the metal part moves to the upper end of the inclined groove 29, the suction cup electromagnet 35 is closed, and the metal part separates from it. Thus, the metal part slowly slides from the inclined groove 29 into the housing 1 through the inclined plate 30. After the metal part is stamped, it is collected. After a batch of metal parts is stamped, the square plate 32 on the side of the housing 1 is rotated by the handle 33 to take out the processed metal parts inside the housing 1. The unified collection can avoid the need to unload the material individually when stamping each mold, thus reducing the stamping efficiency.

[0037] The working principle of this utility model is as follows: The servo motor 27 drives the roller shaft to rotate to complete the feeding of the metal parts. The metal parts are limited to move by the limiting plate 19. After the position of the metal parts is fixed, the cutting plate 16 at the lower end of the U-shaped frame 2 is driven by the sliding mechanism to cut them. After cutting, the metal parts are stamped by the upper mold 7 and the lower mold groove 9. After stamping, the metal parts are separated from the lower mold groove 9 by the lifting mechanism. The third cylinder 34 drives the suction cup electromagnet 35 to move and attract the stamped metal parts. After the suction cup electromagnet 35 is closed, the metal parts are slowly slid into the box 1 through the inclined groove 29 and the inclined plate 30 to complete the unified sorting and collection of the stamped metal parts.

However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
