The hammer head 41 is installed at the upper end of the forging rod 40, and the hammer head 41 is used to forge the outer arc surface of the annular accessory A on the support part 13.

[0068] like Figure 2 , 4 As shown, there are also three locking rods 50, which are installed in the slide groove 12 in a staggered manner with the forging rod 40, the middle end of the locking rod 50 is movably connected in the slide groove 12, the lower end of the locking rod 50 corresponds to the control body 31, the locking rod 50 has a second bias spring and a lock head 51, and the second bias spring is installed at the connection between the locking rod 50 and the slide groove 12.

Then, the telescopic structure 60 is telescopically pressed against the inner arc surface of the annular accessory A to fix the annular accessory A. Finally, the driving device 20 is started to drive the main shaft 21 to rotate to drive the telescopic structure 60 to rotate, and the annular accessory A is driven to rotate.

When the hammer head 41 does not forge, the lock head 51 can release the annular accessory A, which not only enables the lock head 51 to provide a stable working environment for the entire annular accessory A during the forging process, but also does not affect the rotating annular accessory A.

[0078] When the inner arc surface of the annular accessory A needs to be forged, pressure is applied to the sealing column 72 in the air inlet 14 (for example, high-pressure gas is injected), so that the sealing column 72 is forced to move downward and drive the connecting rod 71 to move downward, further driving the pressing ring 70 to move downward to squeeze the lower end of the forging rod 40, driving the forging rod to rotate and drive the hammer head 41 to press against the outer arc surface of the annular accessory A for fixation, and then the rotatable telescopic structure 60 is controlled to repeatedly extend and retract to forge the inner arc surface of the annular accessory A, which can not only realize the forging of the entire outer arc surface, but also realize the forging of the entire inner arc surface by switching the action of the hammer head 41 and the telescopic structure 60.

The air inlet 14 connects the telescopic space with the outside, and the air inlet 14 corresponds to the second air injection cylinder 82. One end of the telescopic rod 62 extends into the telescopic space, and the other end of the telescopic rod 62 faces the inner arc surface of the annular accessory A.

At this time, the replacement plate 83 enters the docking port 64 and contacts the locking plate 65 and presses the locking plate 65 downward, so that the telescopic rod 62 in the telescopic structure 60 is no longer supported by the locking plate 65 and can move in the through hole 831 on the replacement plate 83 to enter the telescopic space, wherein when forging the outer arc surface of the annular accessory A, the locking plate 65 can control the telescopic rod 62 to only support the inner arc surface of the annular accessory A through the effect of rigid fixation, so that it tends to be more stable.

[0086] The first gas injection cylinder 81 is controlled to inject high-pressure gas into the gas inlet 14, so that the sealing column 72 is forced to move downward and drive the connecting rod to move downward, further drive the pressing ring 70 to move downward to squeeze the lower end of the forging rod 40, drive the forging rod to rotate against the outer arc surface of the annular accessory A to complete the fixation, and control the second gas injection cylinder 82 to repeatedly inject high-pressure gas into the vent 63 and repeatedly suck out air, so that the telescopic rod 62 can freely expand and contract, so as to drive the end head to repeatedly forge the inner arc surface of the annular accessory A.
