After the baffle 22 is reset, the first cylinder 3 is started, which pushes the rubber pad 14 into the steel pipe 21. Then the second cylinder 8 is started, which pushes the fixed rod 9 to move, causing the support plate 11 to rotate. Then the support rod 12 slides on the limiting ring 10 and squeezes the spring 13, causing the rubber pad 14 to fit against the steel pipe 21, thereby limiting the steel pipe 21. Then the first cylinder 3 is started again, which moves the steel pipe 21 from the second limiting plate 30 into the necking mold 27. Then the hydraulic cylinder 29 is started, which applies pressure to the necking mold 27 to achieve the necking operation.
