And the length of the pretreatment roller 6 is less than that of the high-efficiency pipe 2.
S2: the push rod 1 extends from one end of the high-efficiency pipe 2 to the inside of the high-efficiency pipe; the pipe driving part drives the high-efficiency pipe 2 to perform circular motion along the axial lead of the high-efficiency pipe, meanwhile, the pretreatment driving part drives the pretreatment roller 6 to perform circular motion along the axial lead of the high-efficiency pipe, and at the moment, the high-efficiency pipe 2 in contact with the pretreatment roller 6 is pre-pressed and hardened.
The outer diameter of the push rod 1 is matched with the inner diameter of the high-efficiency pipe 2; the push rod 1 extends from one end of the high-efficiency pipe 2 to the interior thereof; the high-efficiency pipe 2 is supported; meanwhile, the high-efficiency pipe 2 can be prevented from rotating and bending.
Specifically, the tail end of the push rod 1 positioned in the high-efficiency pipe 2 is provided with the push head 3, and the outer diameter of the push head 3 is matched with the inner diameter of the high-efficiency pipe 2 after pre-pressing and hardening. The outer diameter of the propelling head 3 is smaller than that of the propelling rod 1, and the outer diameter of the propelling rod 1 is matched with the inner diameter of the efficient pipe 2 before pre-pressing hardening. 2 external diameters of high-efficient pipe and internal diameter after this application pre-compaction sclerosis is handled can reduce in step, when propulsion pole 1 and propulsion head 3 stretched into high-efficient pipe 2 inside, the position department of propulsion head 3 was promptly for going on or be about to carry out the position department of pre-compaction sclerosis, and high-efficient pipe 2 internal diameters after the pre-compaction sclerosis and the external diameter looks adaptation of propulsion head 3. Meanwhile, in the pre-pressing hardening process, the high-efficiency pipe 2 moves forwards relative to the pretreatment roller 6, and in the moving forward process, the propelling head 3 and the propelling rod 1 also move forwards synchronously, so that the propelling head 3 is ensured to coincide with the position of the pretreatment roller 6 all the time.
The other end of the high-efficiency pipe 2 is provided with a blanking guide head 4, and the blanking guide head 4 extends into the high-efficiency pipe 2 from the other end thereof; the outer diameter of the blanking guide head 4 is matched with the inner diameter of the high-efficiency pipe 2 after being subjected to pre-pressing hardening; that is, the push rod 1 is inserted from the end of the high-efficiency pipe 2 which is not pre-press hardened, and the blanking guide head 4 is inserted from the end of the high-efficiency pipe 2 which is pre-press hardened.
