[0022] As Figures 1-4 shown, a stamping device with a positioning function includes a lower die 1 and an upper die 2. A stamping groove 3 is opened at the top of the lower die 1. A positioning component 4 is installed inside the stamping groove 3. The positioning component 4 includes six positioning grooves 6, and the six positioning grooves 6 are respectively opened on both sides and the front and rear ends of the stamping groove 3. Two fixing rods 7 are fixedly installed inside the positioning grooves 6. A lifting rod 8 is movably installed outside each positioning groove 6. A first spring 9 is installed at the bottom of the lifting rod 8. A sliding plate 10 and a positioning block 12 are sleeved around the two fixing rods 7. A support rod 11 is installed between the outer side of the sliding plate 10 and the lifting rod 8. Two hanging rods 15 are installed on the outer side of the positioning block 12 and penetrate through the inside of the sliding plate 10. A buffer block 13 is movably installed at the top of the positioning block 12. A second spring 14 is sleeved around the fixing rod 7 and located outside the positioning block 12.

[0023] In this embodiment, the sliding plate 10 and the positioning block 12 are sleeved around the fixing rod 7 and are slidably arranged. The lifting rod 8 penetrates through the inside of the lower die 1 and is slidably arranged up and down. When the upper die 2 descends for stamping, the positioning block 12 is driven by the sliding plate 10 to slide inwards to position the two sides and the front and rear ends of the pressing piece.

[0024] In this embodiment, both ends of the support rod 11 are respectively connected to the sliding plate 10 and the lifting rod 8 through hinge shafts. Both ends of the second spring 14 are respectively in contact with the opposite sides of the sliding plate 10 and the positioning block 12. The upper die 2 contacts the lifting rod 8 and follows it to descend, and the sliding plate 10 is pushed to slide through the support rod 11.

[0025] In this embodiment, the inner end of the hanging rod 15 is fixedly installed with the positioning block 12, and the hanging rod 15 penetrates through the inside of the sliding plate 10 and is slidably arranged. Under the action of the second spring 14 and the hanging rod 15, the positioning block 12 is connected to the sliding plate 10 to provide buffering.

[0026] In this embodiment, a buffer assembly 5 is installed inside the positioning block 12. The buffer assembly 5 includes a buffer groove 16 and a bottom plate 17. The bottom plate 17 is fixedly installed at the bottom of the buffer block 13. The buffer groove 16 is formed inside the positioning block 12. Two contraction grooves 18 are formed at the bottom of the buffer groove 16. A guide rod 19 is fixedly installed inside the contraction groove 18. A third spring 20 is sleeved around the guide rod 19. The buffer block 13 is telescopically arranged at the top of the positioning block 12. Through the telescoping, the top of the buffer block 13 is matched with the thickness of the pressing piece.

[0027] In this embodiment, the length between the two ends of the bottom plate 17 is greater than the length between the two ends of the buffer block 13. The buffer block 13 is arranged to slide up and down in the buffer groove 16 through the bottom plate 17. The buffer block 13 contacts the side of the pressing piece to position the pressing piece.

[0028] In this embodiment, the top end of the guide rod 19 is arranged to slide through the buffer groove 16. The third spring 20 is sleeved around the guide rod 19 and is located between the bottom plate 17 and the contraction groove 18. The buffer block 13 slides up and down to provide buffering and contraction when the upper die 2 is pressed down.

[0029] It should be noted that the present utility model is a stamping device with a positioning function. When in use, a metal pressing piece is placed in the stamping groove 3. The upper die 2 is driven by a hydraulic pump to descend for stamping and forming. When positioning, during the descending process of the upper die 2, it contacts the lifting rod 8, causing the lifting rod 8 to descend and pushing the sliding plate 10 to slide inward through the support rod 11. The metal pressing piece is pressed and positioned by the positioning block 12 and the buffer block 13. Through the expansion and contraction of the second spring 14, the positioning block 12 can adapt to the contraction and sliding for pressing. When the upper die 2 contacts the metal pressing piece for stamping, it contacts the buffer block 13, causing the buffer block 13 to slide downward and contract. The top position of the buffer block 13 is matched with the thickness of the pressing piece. Under the action of the third spring 20, the buffer block 13 automatically slides upward, so that the buffer block 13 always positions the metal pressing piece. After stamping is completed, under the action of the first spring 9, the lifting rod 8 slides upward, and drives the sliding plate 10 and the positioning block 12 to slide outward through the support rod 11 to separate from the workpiece after stamping is completed.
