[0030] The technical solutions in the embodiments of the present application will be clearly and completely explained below with reference to the drawings.

[0031] Embodiment one As shown in Figure 1 , Figure 2 A precision steel pipe processing line, comprising a conveying device 01 and a cutting device 02, further comprising: A dust collection mechanism 1 arranged behind the cutting device and used for removing processing debris and dust on the surface of the steel pipe; A cleaning mechanism 2 arranged behind the dust collection mechanism 1 and used for cleaning oil stains on the surface of the steel pipe, comprising a scraping assembly 21 arranged behind the dust collection mechanism 1 and a scrubbing assembly 22 arranged behind the scraping assembly 21, the scraping assembly 21 scraping most of the oil stains on the surface of the steel pipe and then the oil stains are thoroughly cleaned by the scrubbing assembly 22; A wiping mechanism 3 arranged behind the cleaning mechanism 2 and used for cleaning the inside of the ring groove of the steel pipe, comprising an adjusting assembly 31 and a fitting assembly 32 arranged on the adjusting assembly 31; A wrapping mechanism 4 arranged on the wiping mechanism 3 and used for wrapping a protective film on the steel pipe in cooperation with the wiping mechanism 3.

[0032] In this embodiment, for a precision steel pipe with a ring groove on the surface and a spherical protrusion on the surface, after the steel pipe is processed, metal debris and oil and the like are difficult to clean in the inside of the ring groove, and due to the existence of the protrusion on the surface, conventional brush rollers and the like cannot achieve thorough cleaning, so that oil stains are left in the ring groove and at the root of the protrusion.

[0033] In detail, for the cleaning of the surface of the steel pipe, the metal debris and dust on the surface of the pipe are first adsorbed and cleaned by the dust collection mechanism 1 to avoid scratching the surface of the pipe by the metal debris in the subsequent cleaning process, then the outer surface of the steel pipe is cleaned by the cleaning mechanism 2, the oil stains on the surface are scraped off first, and then scrubbed to achieve a better cleaning effect, the inside of the ring groove is cleaned by the scrubbing mechanism, so that the surface of the steel pipe is thoroughly cleaned, and finally the protective film is wrapped on the surface of the steel pipe by the wrapping assembly, and the protective film is covered to facilitate the protection of the surface of the steel pipe and the subsequent stacking and placement.

[0034] It should be noted that for the cleaning of the steel pipe, in the production process, oil stains may accumulate at the root of the protrusions, and the smooth position may only have some floating oil that is easy to clean. Different areas need to be cleaned in different ways. The existing technology uses a single cleaning method such as a brush roller, which not only fails to clean some dead corners, but also may cause thick oil stains to be transferred to smooth areas, causing the originally oil-free areas to be contaminated with oil stains, resulting in incomplete cleaning.

[0035] Further, as shown in Figure 3 、 Figure 4 The dust suction mechanism 1 includes a suction cavity 11 fixed behind the cutting mechanism, a negative pressure ring 12 arranged at the front end of the suction cavity 11, a suction groove 13 radially slidingly connected in the middle of the negative pressure ring 12, a magnetic attraction ring 14 arranged behind the negative pressure ring 12 and slidingly connected in the suction cavity 11 along the axial direction, and a blowing ring 15 arranged behind the magnetic attraction ring. It also includes an isolation ring 16 arranged at the front end of the suction cavity 11 and a sealing ring 17 arranged at the rear end of the suction cavity 11.

[0036] In this embodiment, by arranging the suction cavity 11, the dust adhering to the surface of the steel pipe, especially the metal debris generated during the machining process, is simultaneously cleaned by wind power, magnetic force and negative pressure suction, thereby avoiding the surface of the pipe from being scratched by the metal debris in the subsequent cleaning process.

[0037] In detail, the steel pipe moves forward into the suction cavity 11, the negative pressure ring 12 performs negative pressure suction, the magnetic attraction ring 14 uses magnetic force to attract the metal debris on the surface of the steel pipe, the blowing ring 15 arranged behind is inclined to the magnetic attraction ring 14, the wind surface everywhere is inclined to the corresponding position of the magnetic attraction ring 14, and the dust and stubborn debris are blown away by wind power, thereby realizing the surface suction cleaning in cooperation with the magnetic force and suction.

[0038] The isolation ring 16 arranged at the front end and the sealing ring 17 arranged at the rear end realize simple sealing of the suction cavity 11, thereby ensuring the suction effect of the negative pressure suction. Since a large number of protrusions are arranged on the surface of the pipe, in order to ensure the suction effect, a plurality of sliding suction grooves 13 are arranged in the suction cavity 11, and the magnetic attraction ring 14 is also arranged as a plurality of sliding magnets. The inner ring of the isolation ring 16 is cut into a jump, and when a protrusion enters, the bending angle of the isolation ring 16 becomes larger. A sensor is arranged behind to determine whether a protrusion enters the suction cavity 11 by the bending angle of the isolation ring 16, thereby controlling the movement of the suction groove 13 and the magnetic attraction ring 14 to make the suction groove 13 and the magnetic attraction ring 14 approach or move away from each other. At the smooth position, the suction groove 13 and the magnetic attraction ring 14 are close to each other, thereby realizing better floating effect. At the protrusion position, the two are far away from each other, thereby avoiding affecting the movement.

[0039] Further, as shown inFigure 5 As shown, the cleaning mechanism 2 scrapes off the components 21 including a rotating ring 211 arranged behind the adsorption cavity 11, a plurality of string wires 212 fixed on the rotating ring 211, a cam 213 rotatably connected at one end of the string wire 212, and a clamping block 214 rotatably connected at the other end of the string wire 212.

[0040] The scraping-off components 21 further include a plurality of spray heads 215 arranged uniformly around the rotating ring 211, a first fan 216 arranged on the upper portion of the rotating ring 211, a plurality of second fans 217 arranged uniformly behind the rotating ring 211, a collection groove 218 fixed below the rotating ring 211, and a plurality of string fixing members 29 arranged on the rotating ring 211. Further, as shown, Figure 6 The string fixing member 29 includes an adaptive rod 291 slidably connected to the rotating ring 211 along the axis of the rotating ring 211, a following ring 292 rotatably connected to the end of the adaptive rod 291, two sets of hinged rods 293 hingedly connected to the following ring 292, and a line pressing wheel 294 rotatably connected to the end of the hinged rod 293.

[0041] In this embodiment, by arranging the string wires 212, the string wires 212 are tightly attached to the surface of the steel pipe by moving the steel pipe, thereby scraping off the oil stains on the surface. Meanwhile, cooperating with the cleaning liquid sprayed by the spray heads 215 and the line pressing wheel 294, the oil stains are cleaned, and the thick oil stains are scraped off from the surface of the steel pipe.

[0042] In detail, when the steel pipe moves into the cleaning mechanism 2, a plurality of string wires 212 are tightly attached to the surface of the steel pipe. With the movement of the steel pipe, the string wires 212 can scrape off the oil stains on the surface of the steel pipe. Meanwhile, since the string wires 212 are thin, the oil stains will not adhere. The spray heads 215 around the steel pipe spray cleaning liquid, cooperating with the scraping of the string wires 212, and the first fan 216 arranged below blows downward, thereby promoting the cleaning liquid to flow downward and making the scraped-off oil stains fall into the collection groove 218 below. The second fans 217 are arranged behind the end of the rotating ring 211 and are inclined toward the surface of the steel pipe, thereby blowing the cleaning liquid on the surface of the steel pipe by the wind force, promoting the cleaning liquid to flow back, and not following the steel pipe to move out of the scraping-off components 21. Since the surface of the steel pipe has protrusions, when the string wires 212 pass through the protrusions, the string wires 212 will be suspended. Therefore, the string fixing member 29 is arranged to press the string wires 212 on the surface of the steel pipe by the line pressing wheel 294, thereby avoiding the suspension of the string wires 212 and causing the scraping-off dead angle.

[0043] It should be noted that the string wires 212 are made of high-strength material. Meanwhile, in order to cope with the processing state, the two ends of the string wires 212 are elastically fixed on the rotating ring 211, that is, when passing through the protrusions, the excess part of the string wires 212 is pulled out from the two ends, thereby lengthening the string wires 212, and in the stable position, the two ends are retracted, and the string wires 212 remain tight.

[0044] It is worth mentioning that the cam 213 is arranged at one end of the string 212, and the string 212 is shaken by rotating the cam 213. The string 212 is shaken in a state of being in tension, and the string 212 is switched to contact the surface of the steel pipe by vibration, so that the string 212 is not worn out quickly by long-time contact with the steel pipe, and the string 212 is not hung by the protrusion to cause a safety accident.

[0045] The clamp block 214 is arranged at the other end of the string 212. After cleaning one steel pipe, the clamp block 214 clamps the string 212 and then rotates, so that the fibers in the string 212 are twisted to squeeze out the cleaning liquid and oil stains, so that the oil stains do not pollute the clean area for a long time.

[0046] Further, as shown in Figure 7 、 Figure 8 The scrubbing assembly 22 includes a positioning ring 221 rotatably connected to the conveying device 01, a plurality of cleaning rollers 222 slidably connected to the positioning ring 221, a steering ring 223 rotatably connected behind the positioning ring 221 and fixedly connected with the positioning ring 221, a first cleaning part 224 and a second cleaning part 225 arranged on the steering ring 223.

[0047] The first cleaning part 224 includes a steering knuckle 2241 fixedly connected to the steering ring 223, an extension rod 2242 fixed to the outer end of the steering knuckle 2241, a spherical wiping block 2243 rotatably connected to the extension rod 2242, an edge cleaning strip 2244 rotatably connected to the outer side of the spherical wiping block 2243, and a cleaning spray hole arranged between the extension rod 2242 and the spherical wiping block 2243. The second cleaning part 225 includes a drive shaft 2251 fixed to the steering ring 223, and a cleaning belt 2252 arranged at three of the drive shaft 2251.

[0048] In the embodiment, the steel pipe on which the surface thick oil stain is removed is thoroughly cleaned by the scrubbing assembly 22, and the residual oil stain on the surface of the steel pipe is removed.

[0049] In detail, the steel pipe moves, the cleaning rollers 222 are arranged obliquely to contact the surface of the steel pipe, and the surface is cleaned. When the protrusion is encountered, the cleaning roller 222 cannot pass through the protrusion and rotates, so that the positioning ring 221 and the steering ring 223 behind the positioning ring 221 rotate, the spherical wiping block 2243 of the first cleaning part 224 is located on the movement path of the protrusion, the spherical wiping block 2243 is close to the protrusion of the surface of the steel pipe, and then rotates to clean. The cleaning spray hole sprays cleaning liquid, and the edge cleaning strip 2244 also wipes and cleans around the protrusion.

[0050] The second cleaning member 225 is colloidally arranged with the first cleaning member 224, the first cleaning member 224 cleans the convex surface, the second cleaning member 225 cleans the position between the convexes, the driving shaft 2251 drives the cleaning belt 2252 to rotate, the cleaning bag wipes the surface of the steel pipe, and the two cooperate to complete the thorough cleaning of the steel pipe and remove the oil stains on the surface.

[0051] It should be noted that the spherical wiping block 2243 fits the surface of the convex, and through the arrangement of the universal joint 2241, the spherical wiping block 2243 can realize comprehensive cleaning of the convex position, and the edge cleaning strip 2244 arranged at the edge is especially used for cleaning the root position of the convex, and through rotation, the oil mist at the root of the convex is completely removed.

[0052] Further, as shown in Figure 9 , Figure 10 The adjusting assembly 31 includes a cleaning cloth 311 for cleaning the inside of the ring cutting groove of the steel pipe, two groups of positioning blocks 312 hinged on both sides of the steel pipe conveying device 01, a stabilizing block 313 elastically connected below the conveying device 01, a driving roller 314 rotationally connected to the stabilizing block 313, and the cleaning cloth 311 passes through the positioning block 312 and the driving roller 314. It also includes a lifting frame 315 arranged on the conveying device 01 and a stabilizing roller 316 arranged on the lifting frame 315.

[0053] Further, as shown in Figure 11 The fitting assembly 32 includes two groups of control rods 321 hinged on the stabilizing block 313, two groups of biting rollers 322 rotationally connected to the ends of the control rods 321, a torsion ring 323 rotationally connected to the ends of the control rods 321 and located outside the biting rollers 322, and two groups of torsion rollers 324 rotationally connected in the torsion ring 323.

[0054] In this embodiment, by arranging the wiping mechanism 3, the cleaning cloth 311 is clamped into the ring cutting groove, and the cleaning of the inside of the ring cutting groove of the steel pipe is realized.

[0055] In detail, the cleaning cloth 311 is an annular cloth strip, the two ends pass through the positioning block 312, and are driven to rotate by the driving shaft 2251 below. When the steel pipe moves, the cleaning cloth 311 is on the upper surface of the steel pipe, and when the ring cutting groove moves to the position of the cleaning cloth 311, the cleaning cloth 311 is pulled into the ring cutting groove under the elastic action of the stabilizing block 313, the lifting frame 315 is raised, the steel pipe is driven to rotate along the axis by the stabilizing roller 316, and the cleaning cloth 311 also rotates at this time, thereby cleaning and wiping the inside of the ring cutting groove.

[0056] Two end control lever 321 rotation, using the bite roller 322 control cleaning cloth 311 smooth movement and close to the surface of the steel pipe, ring cutting groove has a bottom and two sides, by driving torsion ring 323 rotation, using the torsion roller 324 is cleaning cloth 311 from horizontal to vertical, so as to realize the cleaning of the ring cutting groove side wall wipe.

[0057] It should be noted that, in the prior art, the debris and oil in the ring cutting groove after pipe processing is not easy to clean, especially in the corner position, the existing technology uses brush roller cleaning or cloth wiping, which is easy to appear dead angle, and the oil gathers to one side in the cleaning process, which is also not convenient to clean. The cleaning cloth 311 used in the present application can be customized according to the size of the ring cutting groove, so as to realize cleaning of the so-called position in the ring cutting groove, without dead angle and oil accumulation, and can automatically complete the cleaning of the two sides, avoiding the neglect of the cleaning of the two sides in the prior art.

[0058] It is worth mentioning that the cleaning cloth 311 can be arranged on one side of the steel belt, and the steel belt can be arranged in a buckle type, so as to facilitate replacement of the cleaning cloth 311 on it. The steel belt ensures the strength during rotation, and avoids the downward overlapping of the cleaning cloth 311 when changing from horizontal to vertical, causing cleaning dead angle.

[0059] Further, as shown in Figure 12 The wrapping mechanism 4 includes a movable frame 41 vertically slidingly connected to the conveying device 01 and connected to the control lever 321 through a gear and rack driving mode, a winding roller 42 rotationally connected to the movable frame 41, a pressure roller 43 hingedly connected to both sides of the winding roller 42, a traction roller 44 vertically slidingly connected below the winding roller 42, a cutting knife 45 horizontally slidingly connected to both sides of the traction roller 44, and the pressure roller 43 drives the cutting knife 45 to move through a belt transmission and gear transmission driving mode.

[0060] In the present embodiment, by arranging the wrapping mechanism 4, a protective film is wrapped on both sides of the ring cutting groove, which realizes protection of the surface of the steel pipe and facilitates subsequent stable stacking.

[0061] In detail, when the cleaning cloth 311 is clamped into the ring cutting groove, the control lever 321 rotates correspondingly, the movable frame 41 is driven to descend by the gear and rack, the winding roller 42 releases the protective film, the protective film contacts the surface of the steel pipe and realizes wrapping after passing through the traction roller 44. The pressure roller 43 is arranged on both sides to ensure that the protective film can be closely attached to the steel pipe. As the protective film becomes thicker and thicker, the pressure roller 43 rotates. The pressure roller 43 is connected to the intermediate shaft through a transmission belt, the intermediate shaft drives the cutting knife 45 to move towards the middle through a gear, and when the thickness of the protective film reaches the standard, the cutting knife 45 cuts off the protective film at the same time, and the winding of the protective film is completed.

[0062] It should be noted that due to the protrusions on the surface of the steel pipe, the normal stacking is adopted for the stacking of the steel pipe, which is prone to damage due to the contact of the protrusions with the ground, and when stacked high, the protrusions of two pipe fittings may contact each other, so that they cannot be stably attached together, and are prone to collapse. The protective film wrapped on the surface of the steel pipe has a thickness greater than that of the protrusion, and when stacked, the protective film contacts the ground to isolate the protrusion from the ground. After stacking, the protective film contacts the adjacent steel pipe to increase the contact area, so that they can be stacked more closely and reduce the risk of collapse.

[0063] In the description of the present application, it should be understood that the terms "front and back", "left and right" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only used to facilitate the description of the present application and simplify the description, and do not indicate or imply that the device or component referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the application.

[0064] Of course, in the present technical solution, those skilled in the art should understand that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of one element can be one, and in another embodiment, the number of the element can be multiple, and the term "one" cannot be understood as a limitation on the number.

[0065] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, and any changes or replacements easily thought of by those skilled in the art under the technical hints of the present application should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
