[0033] By adopting the above structure, after the pipeline passes through multiple floating clamping assemblies 2, when the center of the shaping head 502 of the floating shaping head is extended into the center of the pipeline, the height error between the center of the pipeline and the center of the shaping head 502 can be eliminated; the floating shaping head adopted allows the shaping head 502 to float slightly up and down and left and right, which can eliminate the straightness error caused by eccentricity and slight bending of the pipeline.

[0034] Reference Figure 2 In detail, in this embodiment, the floating clamping assembly 2 includes a fixed seat 201, an upper clamping block 202, a lower clamping block 203 and a guide pin 204. The lower clamping block 203 is fixed on the fixed seat 201, and guide pins 204 are arranged on both sides of the top of the lower clamping block 203. The upper clamping block 202 is sleeved on the outer side of the guide pin 204 and floats up and down along the guide pin 204. The space surrounded by the upper clamping block 202 and the lower clamping block 203 is used for preliminary restriction of the pipeline. The pin head on the guide pin 204 has a floating gap from the upper surface of the upper clamping block 202. When the shaping head 502 extends into the center of the pipeline, the upper clamping block 202 can float up and down along the guide pin to eliminate the height error between the center of the pipeline and the center of the shaping head.

[0035] Reference Figure 4In detail, in this embodiment, the floating shaping head includes a floating joint 503 and a shaping head 502. One end of the shaping head 502 is connected to one end of the floating joint 503, and the other end of the floating joint 503 is connected to one end of the shaping rod 501 away from the second slide 602. The floating joint 503 is a standard part. The model of the floating joint 503 used in this embodiment is F-M26X150F. The principle thereof is not elaborated here. The shaping head 502 is connected to the shaping rod 501 through the floating joint 503, so that the shaping head 502 can float slightly up and down and left and right, thereby eliminating the straightness error caused by eccentricity and slight bending of the pipeline.

[0036] Working principle: manually pass the pipeline through multiple lower clamps 203 in sequence, and then clamp the pipeline through the guide pin 204 and the upper clamp 202. The upper clamp 202 is sleeved on the outer edge of the guide pin 204 and floats up and down along the guide pin 204 to eliminate the height error between the center of the pipeline and the center of the shaping head 502; then set the shaping times, start the switch of the moving device 6, and the moving device 6 drives the floating shaping head through the shaping rod 501 to automatically shape the pipeline. The floating shaping head used allows the shaping head 502 to float slightly up and down and left and right, which can eliminate the straightness error caused by eccentricity and slight bending of the pipeline; after the shaping is completed, the pipeline is removed manually.
