the cooling jacket 21 and the cooling part 11 shape the pipeline, so that the pipeline becomes a perfect circle, a hose on the outer wall cooling component 2 injects cooling liquid into the second cooling channel 211, the pipeline is cooled, the cooling liquid flows from the first end of the cooling jacket 21 to the second end, the cooling liquid in the second cooling channel 211 can cool and solidify the pipeline far away from the cooling part 11 at first, so that the pipeline can keep a shape outside the outer wall cooling component 2, the pipeline can enter a cooling box for further cooling, the viscosity between the cooled pipeline and the metal wall is lower, if the pipeline between the cooling jacket 21 and the cooling part 11 is cooled first at a part near the cooling part 3, the part pushes uncured fluid raw material when moving, the part deforms, the cooling liquid cannot maintain the perfect circle, the hose on the connecting column 3 injects the cooling liquid into the first cooling channel 111, the cooling liquid flows along the first cooling liquid channel 111, flows to the first end of the cooling part 11, and enters the first cooling channel 113, a heat insulation layer around the first cooling liquid channel 111 can slow down the heat loss layer, the cooled pipeline can keep the cooling liquid in the cooling box at the first end of the cooling channel far away from the cooling part 11, the cooling liquid can keep the cooling box at the cooling channel far away from the cooling part 113, so that the cooling liquid can flow from the cooling box can flow far away from the cooling channel is cooled by the cooling part 11, and can be fully cooled by the cooling liquid flowing through the cooling channel;
when the cooling liquid flows through the check point 119 on the first cooling channel 113, the check point 119 can sense the temperature of the cooling liquid, when the temperature of the cooling liquid flowing through the check point 119 is higher than the temperature in a normal state, an expansion body in the storage cavity 118 expands and pushes a baffle plate 116 for blocking a channel between the feedback liquid channel 115 and the first cooling channel 113 to move, the feedback liquid channel 115 is communicated with the first cooling channel 113, part of the cooling liquid enters the feedback liquid channel 115 and flows to the outer side of the connecting column 3 along the feedback liquid channel 115, a worker is reminded of insufficient cooling liquid, the cooling effect needs to be improved by increasing the amount of the cooling liquid, after the temperature flowing through the check point 119 is recovered to be normal, a spring pushes a push plate 117 to move, the baffle plate 116 blocks the feedback liquid channel 115 from the first cooling channel 113 again, and the cooling work continues;
when the cooling liquid is discharged through the liquid outlet channel 114 after the work is completed, the cooling liquid moves along the guide plate 123 when flowing through the driving mechanism, impacts the upper half part of the impeller 124, so that the impeller 124 rotates, the impeller 124 drives the first sprocket 125 to rotate, the first sprocket 125 drives the second sprocket 126 to rotate through a chain, then drives the coating roller 121 to rotate, a poking block 129 on a mounting plate 127 on the coating roller 121 pokes a convex strip 128 on an adjacent coating roller 121 to drive the adjacent coating roller 121 to rotate, and then the coating rollers 121 synchronously rotate, more plastic lubricant can be coated on the inner wall and the outer wall of the pipe prototype, and the adhesion between the pipe and the inner wall cooling assembly 1 or the outer wall cooling assembly 2 during cooling is avoided;
the pipeline that comes out from outer wall cooling component 2 is cooled down through cooling jacket 21 and cooling portion 11, and the pipeline has preliminary cooling shaping, and the intensity of pipeline obtains preliminary improvement, has avoided the pipeline to leave outer wall cooling component 2 back deformation, and then the pipeline gets into the cooler bin, further cooling solidification.
