S4 is executed.

S4: the clamping driving mechanism 891 drives the movable clamping arm 8911 to rotate upwards, so that the clamping device 89 releases the eccentric flange 18, and the follow-up first lifting device 88 drives the clamping device 89 to lift, so that the outer frame 3 is separated from the pipe die, and the pipe die moves relative to the die spotting machine. S5 is executed.

S5: the clutch 214 is switched to the engaged state, and the traveling drive device 21 drives the outer frame 3 to move on the rail 9 at a lower moving speed relative to the pipe mold conveying speed, so as to prevent the pipe mold from conveying too fast and missing the next eccentric flange 18. If the moving speed of the pipe die is slow, the walking driving device 21 can be omitted, and the die spotting machine can be static on the rail 9 to wait for the pipe die to move continuously. At the same time, S2 is executed again, the first sensor 893 is lowered again to detect whether the next eccentric flange 18 is in place, and after the flange is in place, the flange is clamped again and then the mounting and dismounting are performed.
