Description

Technical Field

[0001] This invention relates to the field of metal processing equipment technology, specifically to a shaping device and method for processing raw material components for wind turbine towers. Background Technology

[0002] Wind turbine towers are the core supporting structure of wind power generation systems. They typically consist of a tower casing, a base, and connecting and supporting components, used to mount wind turbine generators (such as nacelles and blades) and stably support them on land or at sea. Their primary function is to ensure the stable operation of wind turbine generators under various environmental conditions, maximizing the capture of wind energy and its conversion into electrical energy.

[0003] During the processing of steel plates for the tower body, flat plates need to be rolled into arc-shaped sections that meet design requirements. However, existing technologies suffer from the following technical bottlenecks: 1. Traditional rolling equipment (such as plate rolling machines) only completes the plastic deformation of steel plates, without simultaneously treating the oxide scale, cutting burrs and welding residues on the steel plate surface. This results in excessive surface roughness of the cylinder section, requiring additional manual grinding and polishing, which is inefficient and difficult to guarantee quality.

[0004] 2. When steel plates are polished, a large amount of metal dust and fumes are generated. Existing technologies mostly use independent dust collection devices (such as blower dust collection systems), which can easily cause the fumes to escape and result in substandard air quality in the workshop.

[0005] A shaping device and method for processing raw materials and components for wind turbine towers are proposed to solve the aforementioned technical problems. Summary of the Invention

[0006] The purpose of this invention is to provide a shaping device and method for processing raw materials and components for wind turbine towers, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a shaping device for processing raw material components for wind turbine towers, comprising: The base consists of a base and two side supports vertically mounted on top of the base. Two drive rollers are symmetrically and rotatably connected within each side support. A hydraulic clamping rod is installed on each side support, and a conical clamping roller is rotatably connected to the bottom of each hydraulic clamping rod. The two drive rollers are driven by a transmission unit installed on one side of the base top. The two drive rollers, in conjunction with the clamping roller, curl the steel into a conical steel plate. An auxiliary cleaning mechanism is installed on the inner side of each side support. A grinding mechanism is installed in the middle of each side support at the same horizontal level as the inner and outer walls of the steel plate. The two grinding mechanisms are interconnected at both ends via a negative pressure adsorption mechanism and connected to a reciprocating hydraulic rod on one side of each side support. The reciprocating hydraulic rod synchronously drives the two grinding mechanisms to simultaneously process the inner and outer walls of the steel plate, with the negative pressure adsorption mechanism providing additional processing.

[0008] As a further improvement to the above scheme, the transmission unit consists of a drive motor, a drive gear, a universal joint, and three transmission gears. The drive motor is installed on one side of the top of the base. The drive motor is connected to the universal joint and the drive gear in sequence, and the drive gear meshes with one of the transmission gears. Two drive gears are coaxially mounted on the same side of the two drive rollers, and the two drive gears are driven by another drive gear in the middle to ensure that the rotation direction of the two drive rollers is consistent and to cooperate with the pressure roller to curl and round the steel.

[0009] As a further improvement to the above solution, the auxiliary cleaning mechanism includes an auxiliary hydraulic rod fixedly installed directly above the clamping hydraulic rod. A connecting plate 1 is connected to the telescopic end of the auxiliary hydraulic rod. A connecting plate 2 is fixedly connected to one side of the connecting plate 1. A horizontal guide frame is fixedly connected to both sides of the bottom end of the connecting plate 2. A positioning ring is fixedly connected to the outer wall of the clamping hydraulic rod by bolts. Two oblique guide frames are fixedly connected to the inner side of the positioning ring. The extension directions of the two oblique guide frames intersect downwards. Two sliding blocks slide inside each of the two oblique guide frames. A threaded sleeve plate is fixedly connected to the same side of each of the two sliding blocks. An adjusting motor is installed at one of the sliding blocks located at the same oblique guide frame. A screw is connected to the output end of the adjusting motor and is threadedly connected to the two threaded sleeve plates in sequence through the screw to adjust the distance between the two adjacent sliding blocks. A rotating shaft is rotatably connected to the middle of each of the two sliding blocks. A clamping roller is connected to the inner end of each of the two rotating shafts. The two clamping rollers located at the same oblique guide frame are located at the inner and outer walls of the steel plate respectively. A sliding rod is fixedly connected to one side of each adjusting motor. Each sliding rod slides with the adjacent horizontal guide frame.

[0010] As a further improvement to the above solution, the grinding mechanism includes a fixed rod horizontally fixedly connected to two side support seats. A movable frame is horizontally reciprocatingly slidably connected to the fixed rod. One side of the movable frame is fixedly connected to a reciprocating hydraulic rod. The two sides of the middle of the two movable frames are respectively fixedly connected to the two sides of a negative pressure adsorption mechanism. Rotating slots are evenly opened in the middle of the side of the two movable frames facing the steel plate. A connecting turntable is rotatably connected in each rotating slot. An inner connecting pipe is coaxially fixedly connected to the outer end of the connecting turntable. An arc-shaped grinding disc is vertically slidably connected to the inner / outer wall of the steel plate. A push spring is connected to the middle of the arc-shaped grinding disc and the connecting turntable. A cylinder rod is coaxially fixedly connected to the inner end of the connecting turntable. A sector gear is coaxially fixedly connected to the outer wall of the cylinder rod.

[0011] As a further improvement to the above scheme, a fixed rod is fixedly connected to an inner frame plate inside the movable frame. A rack plate is symmetrically installed on the inner side of the inner frame plate. The two rack plates are intermittently connected to a sector gear to ensure that the cylinder rod rotates in the same direction when the reciprocating hydraulic rod drives the movable frame to move horizontally. Multiple outer cylinders are fixedly connected sequentially and evenly inside the movable frame. A guide rod is fixedly connected to the inner wall of the outer cylinder and is slidably connected to a spiral groove. An air hole is opened at the connection between the plug plate and the inner rod, and a one-way valve is provided at the bottom end of the plug plate, which only supports the inner rod to the bottom of the arc-shaped grinding disc. When the end slides, the gas in the gas chamber is discharged from the outlet. When the inner rod moves away from the arc-shaped grinding disc, the external gas enters the gas chamber through the air hole and the one-way valve. The arc-shaped grinding disc, the inner connecting pipe, and the inner rod form the gas chamber. The arc-shaped grinding disc has an outlet on the same axis to enable the gas chamber to interact with the outside. A stopper plate is radially slidably connected in the gas chamber. An inner rod is coaxially fixedly connected to the middle of one side of the stopper plate. A limiting slider is fixedly connected to the outer wall of the inner rod. The limiting slider slides vertically in the gas chamber. A spiral groove with the ends connected is opened on the upper part of the outer wall of the inner rod.

[0012] As a further improvement to the above solution, the negative pressure adsorption mechanism includes connecting frames fixedly connected to one side of the two movable frames on both sides. Two fan covers are symmetrically installed in the middle of the connecting frames. A fan motor is installed in sequence inside the two fan covers. A rotating rod is fixedly connected to the output end of the two fan motors in sequence. A fan blade is fixedly connected to the outer wall of the two rotating rods on the same axis. A cleaning brush is installed coaxially on the outer wall of the two rotating rods. The bottom end of the fan cover is sloped towards the steel plate. A collection chamber is inserted into the bottom end of the two connecting frames in sequence. Each collection chamber is sloped towards the steel plate with the same slope as the inlet.

[0013] The steps for using the cosmetic surgery equipment are as follows: S1. Steel pretreatment and conveying; S2, Curling and Simultaneous Rounding; S3. Simultaneous grinding, polishing and iron filings treatment; S4. Quality inspection and workpiece removal; S5. Welding and final inspection.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention achieves synchronous curling and rounding of steel by driving the transmission roller and the pressing roller through the transmission unit. At the same time, the grinding mechanism polishes the inner and outer walls of the steel plate synchronously under the drive of the reciprocating hydraulic rod, which reduces the time of traditional multi-process switching and improves production efficiency.

[0015] 2. Through the elastic design of the arc-shaped polishing disc and the synergistic effect of the negative pressure adsorption mechanism, the equipment can polish in real time during the rolling process, eliminating oxide scale and burrs, ensuring that the surface roughness of the wind turbine tower body meets the requirements, avoiding the quality fluctuations of traditional manual polishing, and improving product consistency.

[0016] 3. This invention uses a negative pressure adsorption mechanism to simultaneously adsorb iron filings and dust during grinding, and filters the flue gas through carbon adsorption cotton, thus solving the problem of dust emission in the prior art, meeting environmental protection standards, and improving the workshop working environment.

[0017] 4. The present invention can adjust the tapered size of the steel plate parts by means of an auxiliary cleaning mechanism via an inclined guide frame, so that the equipment can handle tower parts of different specifications, thereby improving the versatility of the equipment and reducing customization costs.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] This invention provides a shaping device for processing raw material components for wind turbine towers, comprising: The base 1 and two side support seats 10 vertically mounted on the top of the base 1. Two drive rollers 12 are symmetrically and rotatably connected inside the two side support seats 10. A clamping hydraulic rod 14 is installed at each of the two side support seats 10. A conical clamping pressure roller 13 is rotatably connected to the bottom end of the two clamping hydraulic rods 14. The two drive rollers 12 are driven by a transmission unit 11 installed on one side of the top of the base 1. The two drive rollers 12 cooperate with the clamping pressure roller 13 to roll the steel into a conical steel plate 2. An auxiliary cleaning mechanism is set on the inner side of each of the two side support seats 10. A grinding mechanism is set at the middle of each of the two side support seats 10 at the same horizontal height as the inner and outer walls of the steel plate 2. The two grinding mechanisms are connected to each other at both ends by a negative pressure adsorption mechanism and a reciprocating hydraulic rod 417 is connected to one side of the side support seat 10. The reciprocating hydraulic rod 417 synchronously drives the two grinding mechanisms to process the inner and outer walls of the steel plate 2 synchronously, and the negative pressure adsorption mechanism is used for coordinated processing.

[0033] Furthermore, an auxiliary support rod 15 is installed on one side of the base 1. The auxiliary support rod 15 consists of a bottom support plate and a support rod, wherein the upper part of the support rod is connected to the outside of the side support seat 10, and the lower part of the support rod is connected to the bottom support plate.

[0034] See Figures 1-5 Since the wind turbine tower is installed in a conical shape, the entire transmission unit 11 drives the transmission roller 12 to rotate. The top view is also conical. In conjunction with the conical pressing roller 13 and the auxiliary cleaning mechanism, the steel plate 2 is completely rolled / rounded. When the steel is rolled, there will be a connection gap. This connection is convenient for the steel plate 2 after it has been rolled and rounded. The contact area between the auxiliary cleaning mechanism and the inner and outer walls of the steel plate 2 is needed to clean the iron filings attached to the inner / outer walls of the steel plate 2.

[0035] In addition, during the curling / rounding process, the two polishing mechanisms simultaneously polish the inner and outer walls of the steel plate 2, and the iron filings and dust are treated together by the negative pressure adsorption mechanism.

[0036] The transmission unit 11 consists of a drive motor, a drive gear, a universal joint, and three transmission gears. The drive motor is installed on one side of the top of the base 1. The drive motor is connected to the universal joint and the drive gear in sequence, and the drive gear meshes with one of the transmission gears. Two transmission gears are coaxially mounted on the same side of the two transmission rollers 12, and the two transmission gears are driven by another transmission gear in the middle to ensure that the two transmission rollers 12 rotate in the same direction and cooperate to press against the pressure roller 13 to curl and round the steel.

[0037] See Figures 1-4The active motor can make the two transmission rollers 12 rotate synchronously in one direction through three transmission gears. On the one hand, it pushes the steel to cooperate with the pressure roller 13 to complete the curling / rounding under the pressure of the hydraulic rod 14.

[0038] Furthermore, cameras are installed at each of the two side support seats 10 to monitor the curling status of the steel plate 2 in real time.

[0039] In addition, the auxiliary cleaning mechanism includes an auxiliary hydraulic rod 3 fixedly installed directly above the clamping hydraulic rod 14. A connecting plate 30 is connected to the telescopic end of the auxiliary hydraulic rod 3. A connecting plate 31 is fixedly connected to one side of the connecting plate 30. A horizontal guide frame 32 is fixedly connected to both sides of the bottom end of the connecting plate 31.

[0040] See Figure 6 The hardness of the connecting plate 31 needs to be adjusted and positioned under the pressure of the auxiliary hydraulic rod 3 so that the clamping roller 310 can roll against the inner / outer wall of the steel plate 2, and clean off the iron filings that adhere to the steel plate 2 during polishing.

[0041] A positioning ring 35 is bolted to the outer wall of the hydraulic rod 14. Two inclined guide frames 36 are fixedly connected to the inner side of the positioning ring 35. The extension directions of the two inclined guide frames 36 intersect downwards. Two sliding blocks 37 slide inside the two inclined guide frames 36 respectively. A threaded sleeve plate 38 is fixedly connected to the same side of each of the two sliding blocks 37. An adjusting motor 34 is installed at one of the sliding blocks 37 located in the same inclined guide frame 36. A screw is connected to the output end of the adjusting motor 34 and is threaded to the two threaded sleeve plates 38 in sequence through the screw. It is used to adjust the distance between the two adjacent sliding blocks 37. A rotating shaft 39 is rotatably connected to the middle of each of the two sliding blocks 37. A clamping roller 310 is connected to the inner end of each of the two rotating shafts 39. The two clamping rollers 310 located in the same inclined guide frame 36 are located on the inner and outer walls of the steel plate 2 respectively.

[0042] See Figure 6 The positioning ring 35 is fixed to the outer wall of the hydraulic rod 14 to ensure the stability of the entire inclined guide frame 36. It can also drive the two sets of clamping rollers 310 to abut against the steel plate 2 when the auxiliary hydraulic rod 3 is pressed down, so as to facilitate and stabilize the cleaning of iron filings from the steel plate 2. Secondly, since the two inclined guide frames 36 are inclined downward and inward, it is convenient for the auxiliary adjustment motor 34 to drive the displacement of the two sliding blocks 37 when the auxiliary hydraulic rod 3 extends and retracts, so as to meet the requirement that the equipment can adapt to the contact of steel plate parts 2 of different sizes.

[0043] In addition, it should be noted that the displacement control of the two auxiliary hydraulic rods 3 and the adjusting motor 34 are coordinated with each other. This is achieved by using PLC control in conjunction with a camera for adjustment control, so as to meet the coordinated adjustment changes of the two auxiliary cleaning mechanisms.

[0044] Finally, it should be noted that before stripping, the clamping roller 310 located on the inner wall of the steel plate 2 must be disengaged from the connection of the steel plate 2.

[0045] Each regulating motor 34 has a slide bar 33 fixedly connected to one side, and each slide bar 33 slides against the adjacent horizontal guide frame 32.

[0046] See Figure 6 When the auxiliary hydraulic rod 3 is pressed down, it will drive the sliding rod 33 to press down through the horizontal guide frame 32, so that the two sliding blocks 37 can slide along the inclined guide frame 36 and squeeze the steel plate 2 closer to each other, so that the two clamping rollers 310 can stick together and clean the iron filings on the steel plate 2.

[0047] Furthermore, two auxiliary cleaning mechanisms are matched with the tapered extension of the steel plate 2. When the steel plate 2 is rolled / rounded, the auxiliary hydraulic rod 3 and the adjusting motor 34 are used to assist in receiving the moving steel plate 2.

[0048] The grinding mechanism includes a fixed rod 40 horizontally fixedly connected to two side support seats 10. A movable frame 4 is horizontally reciprocatingly slidably connected to the fixed rod 40. One side of the movable frame 4 is fixedly connected to a reciprocating hydraulic rod 417. The two movable frames 4 are fixedly connected to the two sides of a negative pressure adsorption mechanism respectively. Rotating grooves are evenly opened in the middle of the side of the two movable frames 4 facing the steel plate 2. A connecting turntable 43 is rotatably connected in each rotating groove. An inner connecting pipe 46 is coaxially fixedly connected to the outer end of the connecting turntable 43. An arc-shaped grinding disc 45 is vertically slidably connected to the inner / outer wall of the steel plate 2. A push spring 44 is connected between the arc-shaped grinding disc 45 and the middle of the connecting turntable 43. A cylinder rod 47 is coaxially fixedly connected to the inner end of the connecting turntable 43. A sector gear 412 is coaxially fixedly connected to the outer wall of the cylinder rod 47.

[0049] See Figures 9-11 The arc-shaped grinding disc 45 and the inner connecting pipe 46 move back and forth vertically by pushing the spring 44, which can adapt well to the size and tapered changes of the steel plate 2. The reciprocating hydraulic rod 417 drives the movable frame 4 to move back and forth, so that multiple cylinder rods 47 drive the arc-shaped grinding disc 45 to grind the inner / outer wall of the steel plate 2.

[0050] In addition, a fixed rod 40 is fixedly connected to an inner frame plate 41 inside the movable frame 4. A rack plate 42 is symmetrically installed on the inner side of the inner frame plate 41. The two rack plates 42 are intermittently meshed with the sector gear 412 to ensure that the cylinder rod 47 rotates in the same direction when the reciprocating hydraulic rod 417 reciprocates to drive the movable frame 4 to horizontal displacement.

[0051] It should be noted that when the movable frame 4 is extended or retracted to the outermost / inner end of the reciprocating hydraulic rod 417, the sector gear 412 completes the switching of the rack plate 42. Then, when the reciprocating hydraulic rod 417 is restarted, it can drive the sector gear 412 and the cylinder rod 47 to continue to rotate.

[0052] Specifically, when the reciprocating hydraulic rod 417 gradually extends to its outermost end, the fixed rod 40 will drive the rack plate 42 on one side and the sector gear 412 to rotate in a meshing state. As the reciprocating hydraulic rod 417 extends to its outermost end, the rack plate 42 on that side will push the sector gear 412 to disengage from it. The sector gear 412 will then contact and mesh with the rack plate 42 on the other side as it rotates.

[0053] Furthermore, the racks at both ends of the sector gear 412 are equipped with identical magnets (as shown here, the S pole). The two rack plates 42 are evenly and alternately equipped with S and N pole magnets respectively. It is important to note that as the fixing rod 40 gradually extends to its outermost end, the rack plate 42 on the front side will gradually detach from the sector gear 412. The rack plate 42 and the outermost part of the sector gear 412 that are in contact with each other are of the same pole (since both ends of the sector gear 412 are S poles, this contact area is also an S pole). Since like poles repel each other, the sector gear 412 can be pushed further towards the rack plate 42 on the other side. Simultaneously, the rack plate 42 on the other side completely detaches from the sector gear 412. The sector gear 412 is about to contact the rack, which is an N-pole magnet. Opposite poles attract each other, further assisting in the switching of the sector gear 412 into mesh. After the switching of the sector gear 412 is completed, the reciprocating hydraulic rod 417 will gradually retract to the innermost end, synchronously driving the sector gear 412 to rotate. When it reaches the innermost end, the currently meshing rack plate 42 and the sector gear 412 finally repel each other at the point of contact, pushing the sector gear 412 to switch to the rack plate 42 on the other side and be attracted by the opposite pole magnet there, completing one cycle of rotation of the sector gear 412. Then, with the movement of the reciprocating hydraulic rod 417, the sector gear 412 achieves complete and continuous rotation.

[0054] It should be added that another implementation of this embodiment is as follows: At the transition connection points between the two rack plates 42 and the sector gear 412, that is, at the connection area between a single rack plate 42 and the sector gear, two rack plates 42 need to be set (one for the connection end and one for the disengagement end). The rack in the current area is horizontally slid along the extension direction of the rack plate 42. In the direction away from the sector gear 412, a spring can be used to connect with the currently sliding rack, and under the elastic potential energy, the connection between the two rack plates 42 and the sector gear 412 is ensured intermittently.

[0055] Secondly, the arc-shaped grinding disc 45, the inner connecting pipe 46, and the cylindrical rod 47 form a gas chamber. The arc-shaped grinding disc 45 has a coaxially opened air outlet 416 to enable the gas chamber to interact with the outside. A stopper plate 410 is radially slidably connected inside the gas chamber. An inner rod 49 is coaxially fixedly connected to the middle of one side of the stopper plate 410. A limiting slider 48 is fixedly connected to the outer wall of the inner rod 49. The limiting slider 48 slides vertically inside the gas chamber. A spiral groove 413 with the ends connected is opened on the upper part of the outer wall of the inner rod 49.

[0056] Multiple outer cylinders 414 are uniformly and sequentially fixed inside the movable frame 4. A guide rod 415 is fixedly connected to the inner wall of the outer cylinder 414, and the guide rod 415 is slidably connected to the spiral groove 413.

[0057] See Figure 11 When the inner rod 49 rotates, it can achieve relative vertical reciprocating sliding by relying on the mutual sliding of the spiral groove 413 and the guide rod 415 to complete the continuous blowing action.

[0058] A vent 411 is provided at the connection between the plug plate 410 and the inner rod 49, and a one-way valve is provided at the bottom of the plug plate 410. The gas in the gas chamber is discharged from the vent 416 only when the inner rod 49 slides towards the bottom of the arc-shaped grinding disc 45. When the inner rod 49 moves away from the arc-shaped grinding disc 45, the external gas enters the gas chamber through the vent 411 and the one-way valve.

[0059] See Figure 11 The one-way valve is not shown. It is used to ensure that the gas chamber is pushed and the gas flows out through the outlet 416 when the inner rod 49 moves back and forth. Since the outlet 416 is located in the middle of the arc-shaped grinding disc 45, the arc-shaped grinding disc 45 can blow iron filings and flue gas at the same time when grinding.

[0060] The negative pressure adsorption mechanism includes a connecting frame 5 fixedly connected to one side of two movable frames 4 on both sides. Two fan covers 50 are symmetrically installed in the middle of the connecting frame 5. A fan motor 51 is installed in sequence inside the two fan covers 50. A rotating rod 52 is fixedly connected to the output end of the two fan motors 51 in sequence. A fan blade 53 is fixedly connected to the outer wall of the two rotating rods 52 on the same axis. A cleaning brush 54 is coaxially installed on the outer wall of the two rotating rods 52.

[0061] Furthermore, a filter iron mesh is provided on the side of the fan cover 50 near the movable frame 4, which ensures normal airflow while blocking iron filings, so that the cleaning brush 54 can sweep the adsorbed iron filings into the collection chamber 55 for unified collection.

[0062] Among them, the fan cover 50 is provided with carbon adsorption cotton in the direction away from the movable frame 4 for filtering the flue gas. The carbon adsorption cotton is not shown here.

[0063] The bottom of the fan cover 50 is sloped towards the steel plate 2. A collection bin 55 is inserted into the bottom of the two connecting frames 5 in sequence. Each collection bin 55 is sloped towards the steel plate 2 at the same angle as the feed inlet 56.

[0064] See Figure 12 The two slopes facilitate the collection of iron filings.

[0065] Specifically, the collection compartment 55 is connected to the connecting frame 5 by horizontally inserting it into the bottom of the connecting frame 5, which is convenient and quick to assemble and disassemble.

[0066] When the present invention is used, after the steel is transported into the equipment, the transmission unit 11 is started to realize the synchronous rotation of the two transmission rollers 12 to pull the steel in, and the two pressing hydraulic rods 14 press down the pressing rollers 13 to provide a third support point for the steel entering, so that the steel is gradually rolled into the steel plate 2.

[0067] At the same time, the reciprocating hydraulic rod 417 is activated, and drives the two movable frames 4 to slide horizontally back and forth along their respective fixed rods 40, so that the arc-shaped grinding disc 45 can always maintain a rotating state and grind the inner / outer wall of the steel plate 2. Furthermore, due to the elastic support of the push spring 44, the arc-shaped grinding disc 45 can always fit the conical steel plate 2 for polishing.

[0068] At the same time, as the cylinder rod 47 rotates, the inner rod 49 will move vertically back and forth within the gas chamber, which will eventually discharge the external air from the air outlet 416 and disperse the iron filings and dust in the contact area.

[0069] Meanwhile, as the curling operation proceeds, the auxiliary hydraulic rod 3 will drive the entire connecting plate 2 31 and the horizontal guide frame 32 to change displacement. With the help of the camera to determine the curling size of the steel plate 2, the two sets of clamping rollers 310 are moved to just clamp the curled steel plate 2. As the arc-shaped grinding disc 45 continues to grind, the clamping rollers 310 can scrape off the iron filings adsorbed and stuck to the steel plate 2, and facilitate subsequent collection and processing.

[0070] During the polishing process, the fan motors 51 on both sides are started simultaneously. The negative pressure generated by the fan blades 53 quickly adsorbs the iron filings and dust into the collection chamber 55 for unified treatment.

[0071] The specific steps for using the cosmetic surgery equipment are as follows: S1. Steel Pre-treatment and Conveying: Sector-shaped steel plates (pre-cut using CNC and with welding bevels) conforming to the wind turbine tower design requirements are conveyed to the equipment. The transmission unit 11 is activated, driving two transmission rollers 12 to rotate synchronously, pulling the steel plates into the processing area. Simultaneously, two hydraulic clamping rods 14 are controlled to press down the conical clamping rollers 13, providing stable support for the steel plates and allowing them to gradually form a cone shape during the rolling process.

[0072] S2. Rolling and Synchronous Rounding: The steel plate is continuously pulled, and with the pressure of the clamping roller 13, it is gradually rolled into a preset conical cylinder (steel plate 2) under the action of two drive rollers 12. During this process, the equipment continuously performs rounding operations to ensure that the roundness, coaxiality, and other geometric parameters of the steel plate 2 meet the design requirements. The auxiliary welding mechanism (including auxiliary hydraulic rod 3, clamping roller 310, etc.) adjusts its position in a timely manner based on the information collected by the camera and PLC control, assisting in the rolling and forming of the steel plate 2 and preparing for subsequent welding.

[0073] S3. Synchronous Grinding and Polishing with Iron Scrap Treatment: The grinding mechanism is activated simultaneously with or immediately after the steel plate 2 is rolled and rounded. A reciprocating hydraulic rod 417 drives two movable frames 4 to slide horizontally back and forth along a fixed rod 40, causing the arc-shaped grinding disc 45 to simultaneously polish the inner and outer walls of the steel plate 2. The arc-shaped grinding disc 45 elastically conforms to the conical surface of the steel plate 2 by pushing a spring 44. Simultaneously, the rotation of the cylinder rod 47 drives the inner rod 49 to move vertically back and forth within the gas chamber, expelling airflow through the outlet 416 to sweep the grinding area, dispersing iron scraps and dust. The negative pressure adsorption mechanism is activated simultaneously; the fan motor 51 drives the fan blades 53 to generate negative pressure, which, through the fan cover 50 and connecting frame 5, adsorbs the iron scraps and flue gas generated during grinding into the collection chamber 55 for unified treatment. An auxiliary cleaning mechanism (such as a clamping roller 310) also scrapes off the iron scraps adsorbed and adhered to the surface of the steel plate 2 during the grinding process.

[0074] S4. Quality Inspection and Workpiece Removal: Once the camera identifies that the current steel plate 2 is fully rolled, has a satisfactory surface quality, and meets the subsequent welding conditions based on the collected information, the auxiliary welding mechanism (such as clamping roller 310) will gradually disengage from the steel plate 2. Subsequently, the processed steel plate 2 will be removed from the equipment using a high-strength magnetic crane (or other suitable lifting equipment, taking into account the magnetism of the steel plate).

[0075] S5. Welding and Final Inspection: The removed steel plate 2 is transferred to the welding station for welding (e.g., longitudinal seam welding). After welding, necessary inspections are performed on the weld and steel plate 2 (e.g., non-destructive testing, dimensional accuracy inspection, flatness inspection, etc.) to ensure that its quality meets the technical standards for wind turbine towers.

[0076] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
