The base 1 fixes parts on the press. A displacement chute is provided on the base 1. The forging bar 2 is installed in the displacement chute. A number of forging cavities 9 are evenly provided on the forging bar 2. The left pressing die 3 and the right pressing die 4 are installed on the base 1 and are located on both sides of the displacement chute. Two side forging oil cylinders are installed on the press and the piston rods are respectively between the left pressing die 3 and the right pressing die 4. The shearing oil cylinder 7 is installed on one side of the base 1 and the piston rod is connected to the shearing head 8. The shearing head 8 is arranged between the left pressing die 3 and the right pressing die 4. The displacement forging head 5 is slidably connected to the press head. The material displacement oil cylinder is installed on the press head and the piston rod is connected to the displacement forging head 5. The rotating column 11 is rotatably connected to the base 1 and is connected to the rotating device. A tooth base displacement groove 13 is provided on the rotating column 11. A rotating forging cavity 12 is provided in the tooth base displacement groove 13. An impact hole oil cylinder is installed on the base 1 on one side of the rotating column 11. A punch is connected to the piston of the impact hole oil cylinder. The punch penetrates through the base 1, the rotating column 11 and the rotating forging cavity 12. Tail material guide holes 10 are provided on the forging bar 2 and the base 1 between the forging cavity 9 close to the shearing head 8 and the adjacent forging cavity 9. It further comprises an oil cylinder 32 and a shaping block 33. Chutes 31 are provided on both the left pressing die 3 and the right pressing die 4. The oil cylinder 32 is installed in the chute 31 and the piston is connected to the shaping block 33. The displacement forging head 5 comprises a number of forging heads and a sliding seat. A number of the forging heads are connected to the sliding seat. The forging head above the rotating column 11 is rotatably connected to the press head. At least two insertion holes 14 are provided on the rotating column 11. An insertion column is connected to the forging head above the rotating column 11.

[0018] The worker pre - places the heated iron column into the first forging cavity 9 near the shearing head 8. The press drives the displacement forging head 5 to press down to complete a stamping and forging to fix the shape. Then the press drives the displacement forging head 5 to rise and reset. Then, the shearing oil cylinder 7 is activated to drive the shearing head 8 to shear the rough blank of the excavator tooth seat 6 in the first forging cavity 9 to form the slot of the tooth seat. The slot is used for clamping on the bucket. Before the shearing head 8 shears, the oil cylinders 32 on the side pressing die 3 and the right - hand side pressing die 4 drive the shaping blocks 33 to approach, so that the two shaping blocks 33 cooperate with the shearing head 8 for shearing to play the role of a cutting edge. The tail material after shearing is exported through the tail - material guiding hole 10. After completing the slot stamping, the shearing oil cylinder 7 drives the shearing head 8 to reset. Then the press drives the displacement forging head 5 to press down. Then the material displacement oil cylinder drives the displacement forging head 5 to move, so that the displacement forging head 5 moves into the slot. The displacement forging head 5 and the slot are provided with lugs, so that the excavator tooth seat 6 is clamped on the displacement forging head 5. Then the side forging oil cylinder drives the left - hand side pressing die 3 and the right - hand side pressing die 4 to move away from the forging bar 2. The press drives the displacement forging head 5 to rise, and then the material displacement oil cylinder drives the displacement forging head 5 to move so that the excavator tooth seat 6 thereon moves above the next forging cavity 9. The press drives the displacement forging head 5 to descend so that the excavator tooth seat 6 enters the forging cavity 9. Then the left - hand side pressing die 3 and the right - hand side pressing die 4 close to carry out die - casting to complete the steel stamp or dimension shaping. The material displacement oil cylinder drives the displacement forging head 5 to return. In this way, multiple forging steps are completed in a cycle. The gap between the left - hand side pressing die 3 and the right - hand side pressing die 4 exactly matches the displacement forging head 5 to ensure that the displacement forging head 5 can move back and forth. Since the slot of the excavator tooth seat 6 and the tooth - tip mounting hole of the excavator tooth seat 6 are set at 90 degrees, the excavator tooth seat 6 needs to be rotated 90 degrees. The rotating device drives the rotating column 11 to rotate 90 degrees. At the same time, the insertion column is inserted into the insertion hole 14, which can synchronously drive the forging head above it to rotate. Then the punching oil cylinder drives the punch to carry out punching processing on the excavator tooth seat 6.
