[0033] Embodiment
[0034] Referring to Figure 1-7 , an embodiment provided by the present invention: An adjustable stamping die, including a lower die 1, installation grooves 2 are opened on both sides of the upper end of the lower die 1, a partition board 3 is arranged between the two installation grooves 2, worms 4 are fixedly arranged on both sides of the partition board 3, inner screws 11 are spirally arranged on the outer ends of the two worms 4, bearings 10 are rotatably sleeved on the outer ends of the two inner screws 11, a die groove 9 is fixedly arranged on the outer ends of the two bearings 10, handles 5 are fixedly arranged on the opposite sides of the two worms 4, first telescopic rods 6 are fixedly arranged at the four corners of the upper end of the lower die 1, an upper die 7 is fixedly arranged at the upper ends of the four first telescopic rods 6, a stamping mechanism 8 is fixedly arranged at the upper end of the upper die 7, the stamping mechanism 8 includes a stamping head connecting column 801 and two limiting rods 804, a conical stamping head 802 is fixedly arranged at the lower end of the stamping head connecting column 801, first chutes 805 are opened on both sides of the conical stamping head 802, slide balls 803 are rotatably arranged at the inner ends of the two first chutes 805, second chutes 806 are opened on the opposite sides of the two limiting rods 804, fixed blocks 807 are fixedly arranged on the opposite sides of the two limiting rods 804, and a double-acting telescopic rod 808 is fixedly arranged between the two fixed blocks 807. When adjusting the lower die 1, rotate the handles 5 at both ends of the worm 4, the inner screws 11 sleeved on the outer ends will rotate at the inner ends of the bearings 10, and then drive the die groove 9 at the outer ends of the bearings 10 to move at the inner ends of the installation grooves 2. When the upper die 7 is pressed down, the limiting rods 804 at the lower end of the conical stamping head 802 will slide at the inner ends of the first chutes 805 and the second chutes 806 at both ends of the conical stamping head 802 due to the slide balls 803 to change the style of the stamping head of the upper die 7, and then the conical stamping head 802 punches the metal at the inner end of the die groove 9.
[0035] By rotating the handles 5 at both ends of the worm 4, precise adjustment and position movement of the lower die 1 can be achieved, with the inner screw rod 11 driving the die groove 9 at the inner end of the installation groove 2 to move. This can ensure that the position and alignment of the lower die 1 can be adjusted as required, thus guaranteeing the accuracy and stability of the stamping operation. The limiting rod 804 at the lower end of the conical stamping head 802 slides within the inner ends of the first sliding grooves 805 at both ends of the conical stamping head 802, which can change the style of the stamping head of the upper die 7. This enables flexible adjustment and change of the stamping head style during the stamping process, thereby adapting to the needs of different workpieces and improving the flexibility and applicability of production.
[0036] Two worms 4 are fixedly arranged at the inner end of the installation groove 2, and two bearings 10 are rotatably arranged between the two handles 5. Due to the arrangement of the worm 4 and the bearing 10, by rotating the handle 5, adjustment of the lower die 1 can be achieved, enabling the die groove 9 at the inner end of the installation groove 2 to move precisely, facilitating the positioning and processing of workpieces. Two sliding balls 803 are slidably arranged on the opposite sides of the two limiting rods 804, and the two sliding balls 803 are slidably arranged at the inner ends of the two second sliding grooves 806. When the sliding balls 803 slide on one side of the limiting rod 804, it can help balance the force transmission and pressure distribution of the stamping head of the upper die 7, thereby ensuring that the stamping operation is more stable and balanced. Through the two sliding balls 803 slidably arranged at the inner ends of the second sliding grooves 806, flexible adjustment of the style and manner of the stamping operation can be achieved. Two fixing blocks 807 are fixedly arranged at the lower end of the conical stamping head 802, and the double-acting telescopic rod 808 is fixedly arranged at the lower end of the conical stamping head 802. The fixing blocks 807 can provide a stable support structure, enabling the conical stamping head 802 to maintain balance and stability during the downward pressing process, avoiding shaking or deviation, and ensuring the accuracy and efficiency of the stamping operation. Through the double-acting telescopic rod 808 at the lower end of the conical stamping head 802, it is ensured that the stamping operation can avoid stamping quality problems caused by uneven forces. The conical stamping head 802 is movably arranged between the two die grooves 9, and the two limiting rods 804 are movably arranged between the two die grooves 9. Since both the conical stamping head 802 and the limiting rod 804 are movably arranged between the die grooves 9, more stable support and guidance can be provided, reducing the friction and unstable factors between the stamping head and the die during the stamping operation, and improving production efficiency and product quality. Two installation grooves 2 are opened between every two of the four first telescopic rods 6. By opening the installation grooves 2 between the first telescopic rods 6, a balanced support structure can be provided, making the position and movement of the telescopic rods more stable and balanced, and thus ensuring the force transmission and operation stability during the stamping process. Two die grooves 9 are fixedly arranged between every two of the four first telescopic rods 6. By fixedly arranging the die grooves 9 between the first telescopic rods 6, a more stable support structure can be achieved. During the stamping process, the die grooves 9 are subjected to more uniform and stable forces, helping to reduce shaking or deviation caused by uneven forces on different parts.
[0037] When the conical stamping head 802 stamps the metal at the inner end of the die groove 9, adjusting the size of the die groove 9 can ensure the matching degree and alignment accuracy between the die and the stamping head, making the stamping process more stable and efficient, and improving production efficiency and product quality.
[0038] Working principle: When adjusting the lower die 1, rotate the handles 5 at both ends of the worm 4. The inner screw rod 11 sleeved on the outer end will rotate at the inner end of the bearing 10, and then drive the die groove 9 at the outer end of the bearing 10 to move at the inner end of the installation groove 2. When the upper die 7 presses down, the limiting rod 804 at the lower end of the conical stamping head 802 will slide at the inner ends of the first chute 805 and the second chute 806 at both ends of the conical stamping head 802 due to the sliding ball 803 to change the style of the stamping head of the upper die 7, and then the conical stamping head 802 stamps the metal at the inner end of the die groove 9.
[0039] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
