Initial position: the movable hydraulic rod 30 is in a contracted state. Each of the expansion hydraulic rods 54 is in an extended state. Each control node slide block 60 is attracted by the large control coil 56 and does not extend out of the control node slide groove 58, and each degreasing spring 63 abuts the degreasing slide block 62 against the bottom end of the degreasing slide groove 65.

Each of the degreasing chain springs 79 presses the degreasing chain slider 78 against the bottom of the degreasing chain chute 81.
The degreasing method of the cold-rolled steel pipe comprises the following specific steps:
the first step is as follows: cleaning the inner surface. The steel pipe to be degreased is inserted into a ring formed by the movable disk opening 26 and the degreasing link 11, and is driven by the motor to rotate and axially displace. Each small control coil 50 and each large control coil 56 are energized and the control node 10 is magnetically coupled to the long control rod 48 and the short control rod 27, respectively. The iron filings and the grease on the surface of the steel pipe are scraped on the grease absorption cloth 74 under the action of the degreasing scraper slide block 76.
The second step is that: and (4) locking at one side. The large control coil 56 in the control node 10 on one side is de-energized, and the control node slider 60 is ejected under the action of the control node spring 59. The rubber cushion block 61 of the control joint is driven to abut against and clamp the steel pipe.
The third step: the de-alicyclic ring is enlarged. Hydraulic oil enters the inner cavity of the expansion hydraulic pump 44 through the expansion oil inlet 47, and pushes the expansion piston 45 to shift the expansion hydraulic rod 54 and the expansion cushion block 52 to displace. The long control rod 48 drives the control joint 10 to move through the small control electromagnet 49 and the small control coil 50. The degreasing slide bar 64 and the degreasing slide block 62 are stressed to overcome the elasticity of the degreasing spring 63. The degreasing links 11 are no longer in contact with each other, and the degreasing ring formed by the degreasing links 11 is enlarged.
The fourth step: the inner surface is turned over. Hydraulic oil enters the traveling hydraulic pump 28 through the traveling oil inlet 14 and the traveling oil inlet pipe 13, and the traveling piston 29 pushes the traveling hydraulic rod 30 to move the traveling block 34 and the traveling slider 36. The moving slider 36 shifts the moving support block 35 and the moving disk 19. The hydraulic oil is injected into the outer main oil path 38 through the outer oil path oil inlet 41 and the outer oil path oil inlet pipe 40, and drives the hydraulic motor 69 to start through the outer branch oil path 67, and the hydraulic motor 69 drives the long rotating shaft 21 and the long gear 22 to rotate. The long gear 22 drives the long rack 16 and the long connecting rod 15 to displace. The long control rod 48 drives the control section 10 and the degreasing link 11 to move, so that the back surface of the fat absorption cloth 74 is opposite. Even if the grease-absorbing cloth 74 originally on the inner surface is positioned on the outer surface. The fat-absorbing cloth 74 originally on the outside is located on the inside.
The fifth step: and (5) replying. The small control electromagnet 49 and the small control coil 50 in the short control rod 27 are energized again. The large control coil 56 and the large control electromagnet 57 are powered again, and the short control rod 27 and the control node 10 are attracted together. And the control joint sliding block 60 is contacted and locked with the steel pipe under the action of the large control coil 56 and the large control electromagnet 57.
