Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of heat dissipation flat tube processing equipment, specifically to a feeding device for a flat tube fin scraper. Background Technology
[0002] Flat tubes, as a key basic component, are widely used in heat exchange equipment such as radiators. The fin-shaving process involves carving continuous fins onto the surface of the flat tube to significantly increase its heat dissipation area, and is a core step in manufacturing high-efficiency radiators. A flat tube fin-shaving machine is a specialized piece of equipment for realizing this process.
[0003] In the automated production process of the flat tube shovel wing machine, the feeding system is the starting point of the entire process, and its performance directly determines the production efficiency, stability and quality of the final product.
[0004] Existing feeding systems often suffer from the following drawbacks: First, during the feeding stage, the lack of efficient and precise guiding and positioning mechanisms makes the flat tube prone to horizontal deviation or sagging, resulting in an incorrect posture when entering the conveying mechanism, which makes subsequent precise clamping and conveying difficult. Second, during the vertical conveying stage, traditional conveying mechanisms often use a single pushing device, which causes idle time in the production cycle during the return stroke, making it impossible to achieve continuous and efficient step-by-step feeding. Moreover, the clamping stability is insufficient, which can easily cause the flat tube to shake, deviate, or even tip over during the conveying process. Finally, during the lubrication stage, traditional oiling methods (such as spraying and brushing) have problems such as uneven oil film, lubricant waste, and pollution of the equipment environment. It is difficult to form a uniform and appropriate lubrication layer on the flat tube cutting surface. This not only affects the forming quality of the subsequent shovel fins, but also aggravates tool wear and shortens tool life due to insufficient lubrication and cooling. Utility Model Content

[0009] A vertical conveying structure is connected to the discharge end of the feeding structure to receive and step-convey the flat tube.
[0010] A lubricating oil coating structure is provided at the discharge end of the vertical conveying structure for coating the shaving surface of the flat tube during conveying with lubricating oil.
[0011] The vertical conveyor structure includes a frame, guide rails mounted on the frame, and a drive mechanism.

[0016] The at least two sets of robotic arms are configured to be driven by the drive mechanism to alternately perform clamping and feeding and releasing and returning actions to achieve continuous step-by-step conveying of the flat tube.
[0017] As a preferred technical solution, the feeding structure includes a support frame and at least one set of support units mounted thereon;
[0018] The support unit includes:
[0019] The feed guide block is equipped with a feed channel that is adapted to the cross-sectional shape of the flat tube;
[0020] A laterally adjustable guide mechanism is provided on the left and right sides of the feeding channel to limit and guide the cutting surface of the flat tube;
[0021] The bottom material support mechanism is located below the feeding channel and is used to support the flat tube and prevent it from sagging.
[0022] As a preferred technical solution, the laterally adjustable guide mechanism includes a pair of mirror-arranged rotary guide units;
[0023] Each of the rotary guide units includes a positioning shaft and a roller rotatably mounted on the positioning shaft;
[0024] The feeding guide block has a waist-shaped adjustment hole for mounting the positioning shaft, and the distance between the positioning shafts is adjusted by pushing the side wall of the positioning shaft with a horizontal tightening bolt, thereby adjusting the guide gap between the two rollers.
[0025] As a preferred technical solution, the clamping component includes a driving member and a clamping block driven by the driving member, the clamping block having a first working surface that mates with one side surface of the flat tube;
[0026] The feeding component includes a feeding seat and a clamping block fixed thereon, the clamping block having a second working surface that mates with the other side surface of the flat tube;
[0027] The drive mechanism is connected to the feeder in a transmission manner.
[0028] As a preferred technical solution, the driving mechanism includes a feeding drive motor and a feeding screw transmission pair. The two ends of the screw of the feeding screw transmission pair are respectively connected to the support frame and connected to the feeding drive motor through a transmission connection component. The nut of the screw transmission pair is fixedly connected to the feeding seat to realize the transmission connection between the feeding seat and the screw.
[0029] As a preferred technical solution, at least one guide post is also fixedly installed on the frame; the feeding seat is connected to the guide sleeve that is slidably connected to the outside of the guide post through a connecting plate.
[0030] As a preferred technical solution, the oil rolling structure includes:
[0031] One or more sets of oil rolling components are arranged symmetrically on both sides of the travel path of the flat base tube. Each side has a self-rotating oil roller and an oil-absorbing medium layer covering the outer periphery of the oil roller and rotating passively with it. During operation, the scraped surface of the flat base tube forms rolling contact with the wetted oil-absorbing medium layer.
[0032] Oil reservoir assembly, used to store lubricating oil;

[0034] As a preferred technical solution, a timing control device is also included, which is electrically connected to the oil pump assembly and is used to control its intermittent start and stop according to a set cycle.
[0035] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0036] 1. The adjustable-pitch rotary guide rollers and bottom material support mechanism form a comprehensive horizontal and vertical limiting and support system for the flat tube. This structure not only adapts to flat tubes of different specifications and achieves stepless adjustment, but also effectively prevents the flat tube from shifting and sagging during feeding, ensuring that the flat tube is guided into the vertical conveyor structure with precise posture and position, laying a solid foundation for subsequent processes.
[0037] The vertical conveyor structure employs two sets of robotic arms working in tandem. Through the coupling design of the clamping and feeding components, and the precise coordination of the lead screw drive and guide column, an alternating cyclical working mode is achieved, where one set clamps and feeds while the other set releases and returns. This design eliminates the idle waiting time of a single feeding mechanism, achieving truly continuous, stable, and step-by-step conveying, greatly improving production efficiency, ensuring the smoothness and reliability of the conveying process, and preventing the swaying and deviation of the flat tube.
[0038] The 3-roller oil structure utilizes a passively rotating oil roller and an oil-absorbing medium layer to uniformly and quantitatively transfer lubricating oil onto the surface of the flat tube through rolling friction and elastic compression. Compared to traditional methods, this method produces a more uniform oil film, avoiding waste and environmental pollution caused by oil dripping. Simultaneously, the excellent lubrication and cooling effects effectively reduce cutting forces and temperatures during the fin-scraping process, significantly improving fin forming quality and greatly extending tool life.
[0039] In summary, this invention organically integrates three major functional modules—feeding, conveying, and lubrication—to construct a complete and highly automated feeding device. The modules work collaboratively and seamlessly, reducing manual intervention and not only improving overall production efficiency but also ensuring the stability of the production process and the consistency of product quality. It is highly suitable for integration into modern automated production lines. Attached Figure Description

[0057] For ease of understanding, the present invention will be described more fully below, and embodiments of the present invention will be given. However, it should be understood that these embodiments are merely for more detailed explanation and should not be construed as limiting the present invention in any way, i.e., they are not intended to limit the scope of protection of the present invention.
[0058] The following are descriptions of terms or words, and unless otherwise defined, all techniques and terms used herein have the meanings commonly understood by one of ordinary skill in the art to which this invention pertains.
[0059] In the description of this utility model, it should be noted that the orientation or positional relationship indicated in the terminology is based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product is usually placed when in use. It is only for the convenience of describing this utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on this utility model.
[0060] like Figure 1 As shown, this utility model provides a feeding device for a flat tube shovel wing machine, including a feeding structure 2, a vertical conveying structure 3, and an oil rolling structure 4.
[0061] The feeding structure 2 is integrated at the entrance of the vertical conveying structure of the wing-shaped flat tube shovel machine. Its core function is to guide and position the flat tube 1 after it enters the shovel machine, providing necessary positional accuracy for subsequent material conveying and shovel operation.
[0062] The vertical conveying structure 3 is used to achieve directional conveying of the flat tube. It adopts an alternating movement of two sets of feeding components 332: when the front feeding component 332 moves forward, it is in a clamping state, pushing the flat tube forward; when the rear feeding component 332 returns, it is in a releasing state. Through this alternating action, continuous step-by-step conveying of the flat tube is achieved. Since the cross-section of the flat tube is roughly rectangular, the two shorter sides of its outer shell are clamping surfaces, which are placed above and below the shovel wing machine for clamping, while the two longer sides are shoveling surfaces, which are arranged left and right in the shovel wing machine.
[0063] The oil rolling structure 4 is integrated between the vertical conveying structure and the shovel structure of the flying wing flat tube shovel machine. Its core function is to uniformly coat the shovel surfaces on the left and right sides of the flat tube before it enters the shovel structure, so as to provide the necessary lubrication and cooling conditions for subsequent high-speed shovel operations, thereby significantly improving the fin forming quality and tool life.
[0064] The following is a detailed description of the specific structure of the feeding device:
[0065] like Figures 2-4 As shown, the feeding structure 2 includes a support frame 22 fixed to the inlet side of the input unit. The support frame 22 is provided with one or more independent support units according to the number of flat tubes 1 being fed at the same time. Each support unit includes a vertical plate-shaped feeding guide block 23, a horizontally adjustable guiding mechanism, and a bottom material support mechanism. The feeding guide block 23 is provided with a feeding channel 24 through it along the traveling direction of the flat tube 1. The geometric contour of the feeding channel 24 is adapted to the cross-sectional contour of the flat tube 1 to be processed. The feeding channel 24 is provided with symmetrical assembly ports 25 on the left and right sides. The assembly ports 25 are connected to the feeding channel 24, forming a cross-shaped opening structure.
[0066] In some specific embodiments, the laterally adjustable guide mechanism includes a pair of mirror-arranged rotary guide units located within the assembly port 25. Each rotary guide unit includes a vertical positioning shaft 26 and a roller 27 rotatably mounted on the positioning shaft 26, with a dynamically adjustable guide gap formed between the two rollers 27. After the flat tube 1 is fed into the feeding channel 24, the two rotary guide units limit the cutting surfaces on both sides of the flat tube 1, restricting the horizontal freedom of the flat tube 1 so that the flat tube 1 can accurately enter the subsequent input unit. During feeding, the cutting surfaces on both sides of the flat tube 1 pass between the two rollers 27. To avoid scratching the cutting surfaces, the outer periphery of the rollers 27 is wrapped with a flexible material such as elastic rubber.
[0067] The feeding guide block has a positioning hole 28 for mounting the positioning shaft 26. The positioning hole 28 is a vertical through hole that passes through the support plate. The two vertical positioning holes 28 located on the same side of the flat tube 1 are coaxially arranged and are clearance-fitted with the positioning shaft 26.
[0068] Furthermore, in a more specific embodiment, in order to accommodate flat tubes 1 of different sizes and specifications, the spacing between the guide components needs to be adjusted according to the thickness of the flat tube 1. Therefore, the positioning hole 28 for mounting the positioning shaft 26 is a waist-shaped adjustment hole, with the long axis of the waist-shaped adjustment hole perpendicular to the thickness direction of the flat tube 1, so as to realize stepless adjustment of the guide gap. The feeding guide block 23 further opens a horizontal pushing hole connecting the positioning hole 28 on the outside of each assembly port 25, and a horizontal tightening bolt 29 is provided in the hole. By pushing the side wall of the positioning shaft 26, the spacing between the positioning shafts 26 is adjusted, thereby adjusting the guide gap between the two rollers 27.
[0069] In some specific embodiments, a bottom material support mechanism is also included, comprising a support notch 210 extending downward from the lower edge of the feed channel 24 and a material support rod 211 horizontally mounted within the notch. Both ends of the material support rod 211 pass through corresponding horizontal mounting holes on the left and right sides of the feed guide block 23, providing additional support for the flat tube 1 with greater length or weight, preventing sagging from affecting the feed. Horizontal locking bolts 212 located at both ends of the material support rod 211 are provided within the horizontal mounting holes for axial positioning.
[0070] like Figures 5-8As shown, the vertical conveying structure 3 can vertically feed two sets of flat tubes. The vertical conveying structure 3 for flat tubes includes a guide rail 31, a robotic arm mechanism, and a feeding drive mechanism. The guide rail 31 consists of two sets of parallel guide rails arranged at the top and bottom. Each set of guide rails 31 is composed of an upper guide rail component and a lower guide rail component arranged opposite to each other. The opposite surfaces of the two components are respectively provided with groove structures extending along the length direction of the guide rail. The flat tube to be processed or transported is arranged in a vertical position between the grooves of the upper guide rail component and the lower guide rail component. The groove structure forms a limiting constraint on the upper and lower sides of the flat tube to achieve stable positioning and guidance of the flat tube in the guide rail. The two ends of the two sets of parallel guide rails 31 are respectively connected to the support frame 22 through a fixed connection structure to form a stable guide rail frame. The robot arm mechanism is slidably connected to the two sets of parallel guide rails through an insert-type fitting structure. The robot arm mechanism includes a clamping component 331 and a feeding component 332 arranged opposite to each other on both sides of the flat tube. The clamping component 331 and the feeding component 332 are structurally coupled through an interlocking mechanical interface. The clamping component 331 is configured to perform the gripping and releasing action of the flat tube. The feeding component 332 is connected to the feeding drive mechanism through a transmission interface to form a power transmission connection. It is configured to realize linear reciprocating motion along the axial direction of the guide rail 31 and drive the clamping component 331 to move in coordination.
[0071] Optionally, the support frame 22 is provided with a feeding guide block, and the two ends of the guide rail 31 are fixedly connected to the support frame 22 through the guide rail seat 32 and communicate with the feeding guide block.
[0072] Optionally, a crossbeam fixing plate 36 is provided between the two support frames 22.
[0073] In some specific embodiments, the clamping component 331 includes a driving member and a clamping block 3313 driven by the driving member. The clamping block 3313 has a first working surface that mates with one side surface of the flat tube 1. The driving member includes a cylinder 3311 and a cylinder seat 3312. One side of the clamping block 3313 forms a slidable limiting connection with the lateral surface of the flat tube in the guide rail 31 through an insert-type mechanical fitting structure. The other side of the clamping block 3313 forms a power transmission connection with the end of the piston rod of the cylinder 3311 through a guide wheel, converting the linear thrust of the cylinder 3311 into a clamping force of the clamping block 3313 on the flat tube. The cylinder 3311 is mounted on the cylinder seat 3312, and the cylinder 3311 and the cylinder seat 3312 are fixedly connected by screws.
[0074] The feeding component 332 includes a feeding seat 3321 and a clamping block 3322 fixed thereon. The clamping block 3322 has a second working surface that mates with the other side surface of the flat tube 1. One side of the clamping block 3322 is slidably limited to the side surface of the flat tube in the guide rail 31 away from the clamping block 3313 via an insert-type mechanical fitting structure. The other side of the clamping block 3322 is connected to the feeding seat 3321, and the clamping block 3322 and the feeding seat 3321 are fixedly connected by screws. The movement trajectory of the feeding seat 3321 is parallel to the axial direction of the guide rail 31, and the flat tube is synchronously displaced by the clamping positioning block.
[0075] The driving mechanism is connected to the feeding seat 3321 via a transmission connection. In some specific embodiments, the driving mechanism includes a feeding drive motor 341, a transmission connection component 342, and a feeding lead screw transmission pair. The feeding lead screw transmission pair includes a lead screw 343 and a lead screw nut. The feeding drive motor 341 is fixedly arranged relative to the support frame 22. The two ends of the lead screw 343 are respectively connected to the support frame 22 and connected to the feeding drive motor 341 through the transmission connection component 342. The lead screw nut that cooperates with the lead screw 343 is located in the feeding seat 3321, thereby realizing the transmission connection between the feeding seat 3321 and the lead screw 343.
[0076] Between the two support frames 22, there are also two guide pillars 35, one upper and one lower. The feeding seat 3321 is connected to the guide sleeve that is slidably connected to the outside of the guide pillar through the connecting plate, thereby realizing the sliding cooperation between the feeding seat 3321 and the guide pillar 35.
[0077] Optionally, the transmission connection component is a coupling.
[0078] Optionally, a motor support base 37 is fixedly provided on the support frame 22, and the feeding drive motor 341 is fixedly installed on the motor support base 37. The output end of the feeding drive motor 341 is connected to the input end of the reducer, and the output end of the reducer is fixed to the lead screw 343, so that the feeding lead screw transmission pair is driven to operate by the rotation of the feeding drive motor 341.
[0079] The working process of the vertical conveyor structure 3 is as follows:
[0080] 1. Clamping process: In the initial state, the cylinder in the robot arm mechanism is in the retracted state, the clamping block maintains a certain gap with the guide rail, and the robot arm mechanism can move freely along the guide rail; when clamping is required, the cylinder in the robot arm mechanism extends by venting, pushes the clamping block to clamp the side of the flat tube in the guide rail, thereby clamping the flat tube.
[0081] 2. Feeding process: The clamping component remains in a clamped state, the feeding drive motor of the feeding drive mechanism starts, providing rotational power, and the transmission connection component transmits the rotational motion of the feeding drive motor to the lead screw. The feeding seat in the robot arm mechanism is connected to the lead screw and simultaneously slides with the guide column, enabling the robot arm mechanism to move linearly. When the flat tube is conveyed to the target position, the cylinder retracts, the clamping block disengages from the flat tube, and the robot arm mechanism slides back to the initial position through the guide column.
[0082] The vertical conveying structure 3 for flat tubes of this utility model can complete the conveying of flat tubes through the coordinated operation of multiple sets of robotic arms, realizing continuous and stable feeding of flat tubes. The specific working process is as follows:
[0083] When two sets of robotic arms work together to feed material, initially, the gripping components of the first set of robotic arms are in a clamped state, while the second set is in a released state. Driven by the feeding drive mechanism, the first set of robotic arms smoothly pushes the clamped flat tube forward along the guide rail. After the first set of robotic arms delivers the flat tube to the predetermined position, its gripping components quickly release the clamping force via a cylinder, making the flat tube movable and returning to the initial position to repeat the process. Simultaneously, the gripping components of the second set of robotic arms clamp the flat tube, and after clamping, continue to push it forward along the guide rail until it reaches the predetermined position. Then, the clamping force is quickly released via a cylinder, making the flat tube movable and returning to the initial position. The two sets of robotic arms work alternately, forming an efficient and continuous feeding cycle.
[0084] like Figures 9-11 As shown, the oil rolling structure includes an oil rolling assembly 41, an oil pumping assembly 42, and an oil storage assembly 43. The oil rolling assembly 41 is arranged symmetrically on both sides of the flat tube's travel path. Each side includes a passively rotating oil roller 411 and an oil-absorbing medium layer 412 tightly covering its outer circumferential surface. During operation, the oil-absorbing medium layer is in contact with the scraped surface of the flat tube. Preferably, the initial spacing between the oil-absorbing medium layers 412 is slightly smaller than the actual width of the flat tube. When the flat tube passes through in a stepping manner, rolling friction is generated between its surface and the oil-absorbing medium layer 412, driving the oil roller 411 to rotate passively. At the same time, under the elastic compression, the oil-absorbing medium layer 412 transfers the internally saturated lubricating oil to the scraped surfaces on both sides of the flat tube in a uniform and continuous manner.
[0085] The aforementioned roller coating method not only avoids problems such as uneven oil film and drip contamination that may occur with traditional spraying or brushing, but also enables lubricant molecules to form a directional adsorption layer on the metal surface, effectively blocking direct contact between the tool and the workpiece, inhibiting the solid diffusion of metal caused by high temperature and pressure, and reducing the risk of tool sticking. In addition, the oil film itself has a high specific heat capacity, which can absorb a large amount of heat in the cutting zone instantly, significantly reducing the local temperature rise and preventing the material from undergoing plastic deformation or sticking due to thermal softening. Furthermore, under high-speed shearing, the lubricant continuously flushes the cutting interface, promptly removing fine chips and avoiding the impact of secondary deposition on the surface quality of the fins, thus laying a reliable process foundation for the high heat flux heat dissipation requirements in a compact space.
[0086] In some specific embodiments, the oil-absorbing medium layer 412 is made of a flexible porous material with capillary adsorption properties, such as non-woven fabric, felt, porous sponge, microporous rubber, polyurethane foam, etc. The flexibility of the oil-absorbing medium layer 412 ensures the adhesion effect to the surface of the flat tube and avoids damage to the base tube. At the same time, the porous structure forms a dynamic balance between oil storage and oil release, which can better maintain a stable oil film thickness.
[0087] In some specific embodiments, the oil storage component 43 is a sealed oil tank that stores special lubricating oil inside, and its bottom is connected to the oil pump component 42 through a pipeline; the oil pump component 42 is an oil pump matched with the oil storage component 43, and its power is based on meeting the continuous wetting requirements of the oil suction medium layer 412.
[0088] In some specific embodiments, the bottom of the oil pump assembly 42 is provided with an oil outlet pipe 44 corresponding to different oil-absorbing medium layers 412. The end of the oil outlet pipe 44 is directly opposite the top of the oil-absorbing medium layer 412, and the distance between them is such that it does not interfere with the rotation of the oil roller 411. To avoid the oil-absorbing medium layer 412 becoming oversaturated due to continuous oil supply, resulting in dripping waste, the opening and closing of the oil pump assembly 42 is controlled by a timing control device. Specifically, a timer 45 is connected in series in the pump body power supply circuit and set to start every 30 and 60 seconds, with each oil supply lasting 2 and 5 seconds. This cycle can be adjusted in real time according to the ambient temperature, oil viscosity, and production rhythm to ensure that the oil-absorbing medium layer 412 is always in the best wetted state and does not overflow. Alternatively, a bracket can be used to fix the oil outlet pipe 44 directly above the oil-absorbing medium layer 412, so that the lubricating oil penetrates the oil-absorbing medium layer 412 evenly in a uniform dripping manner.
[0089] A lubricating oil recovery box 48 is provided on the table surface below the oil rolling assembly 41. Its function is to collect the lubricating oil that seeps out of the oil-absorbing medium layer 412 to prevent it from staining the work surface and causing waste.
[0090] In some specific embodiments, in order to adapt to the needs of high-speed multi-channel production, one wing-scraping machine can simultaneously perform input and wing-scraping operations for multiple sets of base flat tubes; therefore, an oil rolling assembly 41 can be independently configured at each wing-scraping inlet, and the oil pumping assembly 42 can be connected in parallel with multiple oil outlet pipelines 44 through multi-port connectors to supply oil to multiple oil rolling assemblies at the same time, so as to realize synchronous lubrication of multi-channel flat tubes and ensure lubrication stability when multiple sets of base tubes are processed at the same time.
[0091] In some specific embodiments, the oil rolling assemblies 41 are arranged in pairs at the inlet of the wing assembly of the wing excavator, specifically on the vertical support assembly 46 at the inlet of the wing assembly. The support assembly 46 has a guide inlet 461 that matches the cross-sectional shape and size of the flat tube to ensure the lateral positioning accuracy when the flat tube enters. Connecting assemblies 47 are symmetrically arranged on the left and right sides of the guide inlet 461 for fixing the oil rolling assemblies 41, and the gap between the oil absorption medium layers is directly opposite the guide inlet.
[0092] Specifically, the connecting assembly 47 consists of a fixing part and a roller body connecting part: the fixing part is a rigid horizontal connecting rod or connecting plate, which is fastened to the side wall of the support assembly 46 by bolts or welding; the roller body connecting part is a cylindrical shaft vertically set at the top of the fixing part, the outer diameter of which matches the center hole of the oil roller 411, and the two are connected by a miniature rolling bearing to achieve low-friction rotation. This structural design not only ensures the stability of the oil roller 411 when it is passively rotated at high speed, but also reduces the starting torque through the friction reduction effect of the bearing, so that the flat tube can smoothly drive the oil rolling assembly 41 to work even when it passes through at a high speed, thereby continuously outputting a uniform and reliable lubrication effect in high-speed continuous production.
[0093] The working method of the feeding device for the flat tube wing shovel machine provided by this utility model is as follows:
[0094] S1. The feeding structure initially guides and positions the flat tube at the inlet. After the flat tube enters the feeding channel 24, its left and right cutting surfaces are limited by a pair of adjustable elastic rollers 27, restricting its horizontal freedom; the bottom support rod 211 provides support to prevent sagging, ensuring that the flat tube is guided into the vertical conveying structure in the correct posture and position.
[0095] S2. The vertical conveying structure is responsible for conveying the flat tube forward in a step-by-step manner. This structure uses two sets of robotic arms to work alternately: when one set clamps the flat tube, the other set releases and returns. The clamping and releasing are achieved by the cylinder 3311 driving the clamping block 3313, and the feed seat 3321 is driven by the lead screw 343 transmission pair to make linear reciprocating motion along the guide rail 31, thereby realizing the continuous and stable step-by-step conveying of the flat tube.
[0096] S3. Before entering the shovel fin structure, the oiling structure evenly coats the shovel surfaces on both sides of the flat tube with oil. The symmetrically arranged oil rollers 411 are covered with an oil-absorbing medium layer 412, which contacts the surface of the moving flat tube and rotates passively, forming a uniform oil film by rolling and transferring saturated lubricating oil. This oil film plays a role in lubrication, cooling and anti-adhesion, providing protection for the subsequent high-speed shovel fin, ensuring the fin forming quality and tool life.
[0097] It should be noted that the above description is a further detailed explanation of the present invention in conjunction with specific embodiments, and should not be construed as limiting the specific implementation of the present invention to these descriptions; the dimensional data in this embodiment do not necessarily limit the technical solution, but merely illustrate one specific working condition. For those skilled in the art to which this invention pertains, several simple improvements and modifications can be made without departing from the concept of the present invention, and all such improvements and modifications should be considered to fall within the scope of protection of the present invention.
