[0028] like Figure 1-5As shown, this utility model provides a technical solution: a forging die for processing ring forgings, including a forging machine body 1, a base 2, hammers 3, and a blank 4. The base 2 and hammers 3 are both installed inside the forging machine body 1, and the hammers 3 are located above the base 2. A support seat 5 is installed on the upper surface of the base 2, and a die base 6 is rotatably connected above the support seat 5. The support seat 5 provides support force to the die base 6 to maintain the stability of the die base 6. The number of hammers 3 is the same as the number of placement holes 8. The hammers 3 are at different heights, and different forging forces are applied to the blank 4 by the hammers 3 at different heights. The blank 4 is transferred to different hammers 3 in sequence by rotating the die base 6 for forging, and the blank 4 is gradually forged into shape.

[0029] The inner side of the mold base 6 has multiple placement holes 8 arranged in a circular array. The blank 4 is located inside the placement holes 8, which provide placement space for the blank 4. The inner side of the mold base 6 has the same number of inlet and outlet slots 9 as the placement holes 8, and the inlet and outlet slots 9 are connected to the placement holes 8. After the blank 4 is forged, the inlet and outlet slots 9 provide space for the pliers to move, and the pliers can be used to remove the blank 4 from inside the placement holes 8. The inner side of the mold base 6 also has multiple mounting slots 10 arranged in a circular array, and the mounting slots 10 are connected to the inside of the placement holes 8.

[0030] Multiple mounting slots 10 have slide blocks 11 installed on their inner bottom walls. Slider blocks 12 are slidably connected to the inner walls of the slide blocks 11. Springs 13 are installed inside the slide blocks 11. An arc-shaped positioning claw 14 is connected to one end of the slider 12 located outside the slide blocks 11. The arc-shaped positioning claw 14 contacts the outer surface of the blank 4. The mounting slots 10 provide space for the installation of the slide blocks 11, and the slide blocks 11 provide support for the slider 12 and the arc-shaped positioning claw 14, maintaining the stability of the slider 12 and the arc-shaped positioning claw 14.

[0031] One end of the spring 13 is connected to the inner wall of the slide block 11, and the other end of the spring 13 is located inside the slide block 11 with the slider 12. The spring 13 provides elastic pushing force to the arc-shaped positioning claw 14, pushing the arc-shaped positioning claw 14 to contact the blank 4 tightly.

[0032] A control mechanism 15 is provided on the outside of the arc-shaped positioning claw 14. The position of the arc-shaped positioning claw 14 is controlled by the control mechanism 15. The movement of the arc-shaped positioning claw 14 controls the fixing and release of the blank 4. The control mechanism 15 includes an arc-shaped chuck 1501 and a positioning pin 1502. The positioning pin 1502 is installed above the mold base 6. A positioning groove 1503 is opened on the inner side of the arc-shaped chuck 1501. The inner wall of the positioning groove 1503 is slidably connected to the outer surface of the positioning pin 1502. One side of the arc-shaped chuck 1501 is in contact with the upper surface of the mold base 6. A handle 1504 is connected to the outer surface of the arc-shaped chuck 1501. The positioning pin 1502 provides support for the arc-shaped chuck 1501 to maintain its stability. The handle 1504 facilitates the movement of the arc-shaped chuck 1501. Then, the spring 13 is compressed by the slider 12. The compressed spring 13 provides power for the arc-shaped chuck 1501 to reset. The inner side of the slide block 11 is provided with a slide rail 1505. The outer surface of the slide block 11 is connected to a stop rod 1506. The outer surface of the stop rod 1506 is slidably connected to the inner wall of the slide rail 1505. The slide rail 1505 provides space for the stop rod 1506 to move. The slider 12 is controlled to move by the stop block. The inner side of the arc-shaped chuck 1501 is provided with a guide groove 1507. The inner wall of the guide groove 1507 is in slidable contact with the outer surface of the stop rod 1506. When the arc-shaped chuck 1501 rotates, it pushes the stop rod 1506 to move through the guide groove 1507. At the same time, the stop rod 1506 moves and drives the slider 12 to move. The slider 12 moves and drives the arc-shaped positioning claw 14 to disengage from the blank 4 and stop the fixing restriction of the blank 4.

[0033] A power mechanism 7 is provided on the outside of the mold base 6. The power mechanism 7 provides power for the movement of the blank 4. The power mechanism 7 includes a motor 701, which is mounted above the support base 5. The output shaft of the motor 701 is connected to a gear 702. A gear ring 703 is mounted on the outer surface of the mold base 6. The gear ring 703 meshes with the gear 702. The motor 701 serves as the power source, providing power for the rotation of the gear 702. The mold base 6 receives the power from the gear 702 through the gear ring 703, thereby driving the mold base 6 to rotate. After the mold base 6 rotates, it moves the blank 4 to a position. Below the different hammerheads 3, the outer surface of the mold base 6 is connected to a shielding ring 704, and the shielding ring 704 is located above the gear ring 703 and the gear 702. When forging the workpiece blank 4, oxide scale and impurities will be removed. In order to prevent oxide scale and impurities from contacting the gear 702 or the gear ring 703 and causing the operation of the gear 702 and the gear ring 703 to be blocked, the shielding ring is formed above the gear 702 and the gear ring 703 to block the oxide scale and impurities outside the gear 702 and the gear ring 703 and keep the gear 702 and the gear ring 703 clean.

[0034] Working principle: In use, the handle 1504 first pushes the arc-shaped chuck 1501 to rotate. Simultaneously, the rotation of the arc-shaped chuck 1501 pushes the stop rod 1506 to move position via the guide groove 1507. The movement of the stop rod 1506 pushes the slider 12 to move position, compressing the spring 13. The compressed spring 13 provides power for the slider 12 to reset. The movement of the slider 12 pushes the arc-shaped positioning claws 14 to move position, causing the multiple arc-shaped positioning claws 14 to move away from each other, expanding the internal space. Then, the blank 4 is placed inside the arc-shaped positioning claws 14. The handle 1504 is then released to release the control of the arc-shaped chuck 1501. At the same time, the spring 13 pushes the slider 12 and the arc-shaped positioning claws to retract, enclosing the blank 4 inside. Simultaneously, the stop rod 1506... The arc-shaped chuck 1501 is reset by pushing the guide groove 1507. The forging machine body 1 is started, and the forging machine body 1 pushes the hammer head 3 to apply hammering force to the billet 4. After hammering the billet 4, the hammer head 3 moves upward and disengages from the billet 4. The motor 701 is started, and the motor 701 drives the gear 702 to rotate. The gear 702 drives the die base 6 to rotate through the gear ring 703. The movement of the die base 6 causes the billet 4 to move. By rotating and moving the die base 6, the billet 4 is moved to different hammer heads 3 in sequence to receive forging. The billet 4 is gradually forged into the required shape and size of the workpiece. The forged billet 4, which has been forged once, is taken out from the placement hole 8 through the inlet and outlet groove 9. Then, the unforged billet 4 is put into the placement hole 8. The motor 701 is started, and the die base 6 continues to rotate, causing the billet 4 to move.
