Description

Technical Field

[0001] This application relates to the technical field of metal processing equipment and intelligent manufacturing, and in particular to a shower room track arc pressing device. Background Technology

[0002] Shower enclosures are a core component of modern bathroom spaces, and their track system, as a key structure supporting the sliding door, directly determines the product's operational stability and lifespan. Currently, most shower enclosure tracks on the market are made of alloy profiles such as aluminum alloy and stainless steel. These materials combine good mechanical strength and corrosion resistance, meeting the needs of different bathroom layouts for straight, curved, and irregularly shaped tracks. In actual production, to adapt to curved or corner shower enclosures, straight metal track profiles need to be bent. Precise curvature forming processes ensure the track's fit to the installation space, thereby guaranteeing smooth sliding door operation and the overall structural seal.

[0003] In related technologies, to prevent defects such as cross-sectional collapse and wrinkling in thin-walled metal profiles during bending, the industry generally adopts a processing method of internal filling with support materials supplemented by external mechanical arc pressing. First, a specific support medium is filled inside the track profile to enhance its structural rigidity. Then, pressure is applied using an arc pressing device to complete the arc shaping. Currently, the mainstream support materials mainly include two types: corundum and grains such as millet. Corundum particles have high hardness and good flowability, providing significant support; however, their sharp particle edges can easily scratch the inner surface of the track during filling and recycling, damaging the original anti-corrosion coating. While grains such as millet are soft and will not damage the inner wall of the profile, they are susceptible to moisture and mold growth in actual production and storage environments and may attract rodents and insects, posing hygiene and safety hazards.

[0004] Regarding the aforementioned technologies, the main drawback of existing arc-pressing processes is that the stress distribution during bending is difficult to control evenly. Operators rely primarily on experience to judge the degree of bending, which can easily lead to excessive or insufficient local deformation due to improper pressure application, causing track cross-section distortion or cracks. Furthermore, residual stress within the material after bending is difficult to release effectively, resulting in product springback and deviations between the formed track curvature and design dimensions, affecting installation accuracy and operational stability. Summary of the Invention

[0005] In order to improve the uneven stress distribution and springback problem in the arc pressing process, and to improve the dimensional accuracy and product qualification rate of the track forming, this application provides an arc pressing device for shower room tracks.

[0006] The shower enclosure track arc pressing device provided in this application adopts the following technical solution: A shower enclosure track pressing device includes a filling mechanism for filling a profile with supporting material, a pressing mechanism for pressing the filled profile into an arc, and a padding mechanism disposed between the filling mechanism and the pressing mechanism for placing a pad on the profile to be pressed into an arc. A turnover mechanism for conveying the profile is provided between the filling mechanism and the padding mechanism and between the padding mechanism and the pressing mechanism. The arc pressing mechanism includes an arc pressing plate for pressing the profile, a lifting assembly for driving the arc pressing plate to press down / lift up, an arc pressing track for placing the profile to be pressed and cooperating with the arc pressing plate, a column for arranging the lifting assembly and the arc pressing plate, and a base for arranging the arc pressing track and the column.

[0007] By adopting the above technical solution, the automation and process coordination of the track pressing process are realized. The filling mechanism, padding mechanism, and pressing mechanism are connected through a turnover mechanism, reducing reliance on manual labor and minimizing process interruptions. The padding mechanism reduces direct friction between the track and the pressing plate. Combined with the filling support material, it improves the structural stability of the profile during bending, reduces the probability of defects such as cross-sectional collapse and wrinkles, and provides a foundation for high-precision track forming.

[0008] Furthermore, the arc-pressing tracks are symmetrically arranged on both sides of the base to support the two ends of the profile to be pressed into an arc. The arc-pressing tracks are rotatably connected to the base. Each of the two arc-pressing tracks is fixedly connected to a first return spring at its far-away ends. The first return spring is fixedly connected to the base at the end away from the arc-pressing track.

[0009] By adopting the above technical solution, a dynamic balance mechanism is formed between the pressure arc track and the elastic support of the first return spring. During the pressure arc process, the pressure arc track rotates relative to the base as the profile is pressed down and bent, thereby adaptively adjusting the contact angle with the profile to ensure that the pressure is evenly distributed along the length of the profile. After bending is completed, the first return spring drives the pressure arc track back to its normal position, effectively releasing residual stress and avoiding track twisting or springback caused by stress concentration. This improves the conformity of the forming arc with the design dimensions and ensures the operational stability of the product after installation.

[0010] Furthermore, a sliding seat that mates with the profile is slidably installed on the arc-pressing track. A pad for the profile to be inserted is detachably connected to the sliding seat. A limiting piece for abutting the end of the profile is provided on the pad. A second return spring is fixedly connected to the end of the sliding seat away from the limiting piece. The second return spring is fixedly connected to the arc-pressing track at the end away from the sliding seat.

[0011] By adopting the above technical solution, the flexible adjustment of the sliding seat and the detachable pad enable adaptation to profiles with different cross-sections. The limiting plate on the pad can precisely lock the position of the profile end. As the profile gradually bends during the arc pressing process, the sliding seat, driven by the pad and limiting plate, slides relative to the arc pressing track, always remaining at the end of the profile. This ensures the profile stays centered throughout the arc pressing process, effectively suppressing deviation and wobbling, and guaranteeing product dimensional consistency. Combined with the restoring force of the second return spring, the sliding seat is reset by the second return spring after the arc pressing is completed.

[0012] Furthermore, the arc-pressing track is fixedly connected to a hinge seat on its bottom side, and the base is provided with a shaft for the hinge seat to rotate. The length direction of the shaft is perpendicular to the length direction of the arc-pressing track. The base is provided with an adjusting screw and a handwheel for driving the shaft, and a scale for calibrating the position of the shaft.

[0013] By adopting the above technical solution, the mechanical transmission system that adjusts the lead screw and handwheel allows operators to conveniently and quantitatively adjust the position of the shaft on the base, thereby adjusting the maximum tilt angle of the arc-pressing track. The scale, combined with a preset database, directly indicates the correspondence between the profile length and the shaft position, further ensuring adjustment accuracy. The adjustable shaft setting overcomes the limitations of traditional equipment with fixed curvature, adapting to diverse processing needs from small angles to deep curvatures. The angle adjustment process requires no complex calibration, shortening changeover time and improving the equipment's flexible production capacity.

[0014] Furthermore, the pad is fixedly connected to a limiting rod for mounting the limiting piece on one side. The limiting rod is arranged along the extension direction of the pad's length and passes through the limiting piece, and is detachably connected to the limiting piece.

[0015] By adopting the above technical solution, the detachable connection structure of the limiting rod and the limiting piece achieves the functions of quick assembly and disassembly and precise positioning. When changing to different specifications of profiles, the position of the limiting piece can be quickly adjusted to adapt to the profile length and end face characteristics, ensuring the clamping force at the end of the profile, meeting the needs of flexible production, and avoiding scrap caused by positioning deviation through physical constraints, thereby improving the fault tolerance rate of the production line.

[0016] Furthermore, the lifting assembly is provided with a mounting base for mounting the arc-pressing plate. The arc-pressing plate is symmetrically arranged at both ends and hinged with connecting plates for fixed connection with the mounting base. The arc-pressing plate is provided with an adjustment assembly for adjusting the curvature on the arc-shaped inner wall near both ends.

[0017] By adopting the above technical solution, the adjusting bolts at both ends of the pressure plate can simultaneously adjust the radius of curvature of the inner wall of the arc, and with the flexible angle compensation of the hinged connection, the pressure plate fits snugly against the outer contour of the profile. The adaptive adjustment mechanism effectively solves the stress concentration problem caused by the fixed shape of traditional pressure plates, ensuring uniform material deformation during bending and reducing the risk of surface cracks and local thinning.

[0018] Furthermore, the column is provided on one side with a limit valve for cooperating with the lifting assembly and for controlling the downward pressing height of the pressure plate.

[0019] By adopting the above technical solution, the preset pressing height function of the limit valve provides precise control over the stroke end point of the arc pressing plate, avoiding over- or under-pressurization caused by differences in operating experience, ensuring that the deformation amount of each arc pressing meets the specifications, thereby stably controlling the degree of plastic deformation of the material. The uniform pressing depth allows the equipment to be adapted to standardized molds, reducing the difficulty of tooling changeover and ensuring quality stability in production.

[0020] Furthermore, the filling mechanism includes a material holding pool for holding support material, a filling assembly disposed at the bottom of the material holding pool, a receiving hopper located below the material holding pool, and a feeding assembly for conveying support material into the material holding pool. The material holding pool is provided with a support base below for support, and the support base is provided with a sealing component for sealing the end of the profile on one side. The sealing component is arranged adjacent to the filling component, and the feeding component is located on the side of the support base away from the sealing component.

[0021] By adopting the above technical solutions, a fully automated filling system has been established, encompassing support material storage, quantitative conveying, and automatic sealing. The continuous feeding capability of the material tank and feeding components ensures production continuity, while the sealing components can promptly seal the profile ports before and after filling to prevent support material leakage. Furthermore, the integrated design reduces the equipment's footprint, enabling efficient and clean production in small and medium-sized production lines.

[0022] Furthermore, the filling assembly includes a feeding pipe vertically fixedly connected to the bottom of the material holding pool and communicating with the interior of the material holding pool, a solenoid valve fixedly connected to the lower end of the feeding pipe and used to control the opening and closing of the feeding pipe, and a discharge pipe located at the lower end of the solenoid valve and used to dock with the end of the profile. The discharge pipe has a connection port that matches the end of the profile, and the discharge pipe is detachably connected to the solenoid valve.

[0023] By adopting the above technical solutions, precise metering and leak-free delivery of support materials are achieved. The rapid opening and closing of the solenoid valve, combined with the discharge pipe that matches the shape of the profile port, ensures no overflow or blockage during the filling process. The detachable connection facilitates replacement, thus adapting to different profile diameters and port shapes. The intelligent conveying system not only meets the process requirements of high-density filling but also provides convenience for material switching in flexible production.

[0024] Furthermore, the receiving hopper is provided with a lifting assembly for lifting the profile to the position of the filling assembly. The lifting assembly includes a lifting cylinder installed on the inner wall of the bottom side of the receiving hopper and a clamping seat located at the driving end of the lifting cylinder for clamping the end of the profile.

[0025] By adopting the above technical solution, the lifting cylinder and the clamping seat are linked to achieve automatic alignment and lifting docking of the profile from the receiving hopper to the filling station. The clamping seat holds the bottom end of the profile, replacing manual positioning and ensuring the coaxiality of the upper end of the profile and the feeding pipe during filling, eliminating material spillage or insufficient filling caused by alignment deviation. The automated device improves the production line cycle time, reduces human intervention, and lowers operational safety risks.

[0026] In summary, this application includes at least one of the following beneficial technical effects: This application injects supporting material into the profile through a filling mechanism to form continuous internal support, enhancing the bending resistance of the cross-section and preventing collapse, wrinkling, or cracking. The arc-pressing mechanism employs an arc-pressing track that can rotate relative to the base and a first return spring, adaptively adjusting the contact angle during bending to ensure uniform pressure distribution along the length. The sliding seat abuts the end of the profile through a limiting plate, and works with the second return spring to achieve automatic following and centering positioning, suppressing deviation. After bending, the first return spring drives the arc-pressing track back to its original position, releasing residual stress, preventing springback and twisting, ensuring that the formed arc matches the design dimensions, and improving the operational stability after track installation. This application utilizes a transfer mechanism to sequentially connect the filling mechanism, the padding mechanism, and the arc pressing mechanism, allowing the profiles to be automatically transported between each station without the need for manual handling or repeated positioning. The filling mechanism integrates a feeding component, a solenoid valve, and a sealing component. A lifting component raises the profile to the filling station, the solenoid valve precisely controls the amount of support material injected, and the sealing component seals both ends of the profile to prevent leakage. After filling and padding, the profile directly enters the arc pressing mechanism for forming. This integrated process eliminates the manual loading and unloading and waiting time of traditional segmented production, increasing production cycle time and reducing labor intensity and safety risks. To address the diverse needs for shower enclosure track lengths, cross-sectional shapes, and curvatures, this application incorporates adjustable structures in key areas. The curved track is moved horizontally on the base via an adjusting screw and handwheel drive shaft, and its position is precisely set using a ruler, thereby altering the maximum tilt angle to accommodate the curvature of different profile lengths. Adjusting bolts at both ends of the curved plate allow for simultaneous adjustment of the radius of curvature of the inner curved wall, accommodating various curvature requirements from gentle to deep arcs. The discharge pipe of the filler assembly, the pads on the sliding seat, and the limiting plates are all detachably connected, facilitating quick replacement to match different profile ports and cross-sections. This enhances the equipment's versatility and flexible production capabilities. Attached Figure Description

[0038] To make the purpose, technical solution, and advantages of this application clearer, the following description is provided in conjunction with the appendix. Figure 1-10 The present application will be further described in detail with reference to the embodiments.

[0039] This application discloses a shower room track arc pressing device. (Refer to...) Figure 1 The shower enclosure track pressing device includes a filling mechanism 1, a padding mechanism 2, a pressing mechanism 3, and a transfer mechanism 4. The filling mechanism 1, padding mechanism 2, and pressing mechanism 3 are arranged sequentially, while the transfer mechanism 4 is located in front of each of the above mechanisms and is mainly used to clamp the profile to be processed and transfer the profile between the various workstations. Specifically, the filling mechanism 1 is used to fill the inside of the profile with supporting materials such as nylon granules. The padding mechanism 2 is located between the filling mechanism 1 and the pressing mechanism 3 and is used to place a protective pad on the profile to be pressed into an arc shape. The pressing mechanism 3 is used to press the filled and padded profile into an arc shape. The transfer mechanism 4 first clamps the profile at the position of the filling mechanism 1 and fills it through the filling mechanism 1, then transfers the filled profile to the padding mechanism 2 for padding, and finally transfers the padded profile to the pressing mechanism 3 for pressing.

[0040] Reference Figure 1 and Figure 2 The turnover mechanism 4 includes an X-axis moving module 41, a Z-axis lifting module 42, a mechanical gripper 43 for clamping the profile, and a rotation drive 44. The X-axis moving module 41 is arranged along the flow direction of the filling mechanism 1, the padding mechanism 2, and the arc pressing mechanism 3. The X-axis moving module 41 is provided with a translation seat 411 for mounting the Z-axis lifting module 42, and the Z-axis lifting module 42 is provided with a lifting seat 421 for mounting the rotation drive 44. In this embodiment, both the translation seat 411 and the lifting seat 421 are driven by a motor lead screw. The mechanical gripper 43 is mounted on the rotation drive 44, which in this embodiment is a servo motor.

[0041] Reference Figure 3 and Figure 4 The filling mechanism 1 includes a material holding tank 11, a filling assembly 12, a receiving hopper 13, a feeding assembly 14, and a sealing assembly 15. The material holding tank 11 is used to hold the supporting material, and the material holding tank 11 is vertically arranged at the bottom and fixedly connected to a support base 111.

[0042] The packing assembly 12 includes a feeding pipe 121 communicating with the interior of the material storage tank 11, a solenoid valve 122 controlling the opening and closing of the feeding pipe 121, and a discharge pipe 123 connected to the lower end of the solenoid valve 122. The feeding pipe 121 is vertically arranged and fixedly connected to the bottom outer wall of the material storage tank 11. The discharge pipe 123 has a connection port that matches the end of the profile. The solenoid valve 122 is connected between the feeding pipe 121 and the discharge pipe 123. The material pipe and the solenoid valve 122 are detachably connected for easy maintenance and replacement.

[0043] In this embodiment, two sets of filler assemblies 12 are provided, and the encapsulation assembly 15 is arranged at the bottom of the material reservoir 11 and between the two filler assemblies 12. The encapsulation assembly 15 includes a tape slitting machine 151 for automatically releasing and cutting a fixed length of tape, and a clamping seat 152 for pressing the fixed length of tape against the end of the profile. In this embodiment, the clamping seat 152 is driven by a cylinder and can conform to the shape of the end of the profile.

[0044] The receiving hopper 13 is positioned in front of the support base 111 and receives the filling assembly 12 below. The receiving hopper 13 contains a lifting assembly 16. The lifting assembly 16 includes a lifting cylinder 161 mounted on the inner wall of the bottom side of the receiving hopper 13 and a clamping seat 162 mounted on the drive end of the lifting cylinder 161. The clamping seat 162 has a groove structure that matches the shape of the profile end. The operator inserts the lower end of the profile into the clamping seat 162, and the clamping seat 162, through the lifting cylinder 161, lifts the profile to the position of the filling assembly 12, enabling precise filling of the upper end of the profile.

[0045] The feeding assembly 14 is located on the rear side of the support base 111 and is used to batch feed support materials into the material pool 11. The feeding assembly 14 includes a feeding hopper 141 for holding support materials and a sprocket assembly 142 for driving the feeding hopper 141 to lift and rotate. The sprocket assembly 142 can be driven to lift and rotate by the forward and reverse rotation of the motor.

[0046] During the process, the feeding component 14 delivers support material into the material pool 11 to ensure supply. After the clamp holds the vertically oriented profile, it is first moved to align with the encapsulation component 15, and tape is applied to one end of the profile to prevent leakage of the filler material. Then, the profile is rotated by the drive component to adjust its posture, aligning the unsealed tape end with the filler component 12, which injects a fixed amount of support material into the profile. After filling, the turnover mechanism 4 adjusts the position of the profile end to align with the encapsulation component 15 and completes the tape sealing of the profile end. At this point, the profile has completed the filling of support material and the tape sealing of both ends, and is ready to be transported to the next station by the turnover mechanism 4.

[0047] Reference Figure 5 and Figure 6 In this embodiment, the padding includes an upper pad and a lower pad that can be interlocked. The padding mechanism 2 includes a lower platform 21 for fitting the lower pad and an upper platform 22 for fitting the upper pad. An operating platform 23 for horizontal placement of the profile is provided between the upper platform 22 and the lower platform 21. A lifting drive 211 and a top support plate 212 are installed on the bottom side of the lower platform 21, and a top support opening 213 for the top support plate 212 and the lower pad to extend out is provided on the lower platform 21. An operating opening 231 for the top support plate 212 and the lower pad to extend out is provided at the corresponding position of the top support opening 213 on the operating platform 23. A pressing drive 221 and a pressing plate 222 are installed on the top side of the upper platform 22, and a pressing opening 223 for the upper pad and the pressing plate 222 to extend out is provided at the corresponding position of the operating opening 231 on the upper platform 22. In this embodiment, both the lifting drive 211 and the pressing drive 221 are cylinders with fast response capabilities.

[0048] During the process, the lifting drive 211 drives the top support plate 212 and transfers the lower liner to the operating port 231 position on the operating table 23. The profile is clamped by the turnover mechanism 4 and conveyed into the lower liner at the operating port 231 position. Subsequently, the pressing drive 221 drives the pressing plate 222 to press the upper liner down onto the profile at the operating port 231 position and press it together with the lower liner. After the liner is completed, the pressing drive 221 first drives the pressing plate 222 to reset, the turnover mechanism 4 clamps the liner and conveys it to the next station, and the lifting drive 211 then drives the top support plate 212 to reset.

[0049] Reference Figure 7 and Figure 8The arc-pressing mechanism 3 is the core forming unit of the equipment. The arc-pressing mechanism 3 includes a base 31, a column 32, a lifting assembly 33, an arc-pressing track 34, and an arc-pressing plate 35. The base 31 serves as the supporting base for the entire arc-pressing mechanism 3. The column 32 is vertically fixed to one side of the base 31 and supports the lifting assembly 33 above. The lifting assembly 33 is mounted on the column 32. The lifting assembly 33 can be a hydraulic cylinder, a pneumatic cylinder, or a servo electric push rod. In this embodiment, the lifting assembly 33 is preferably a hydraulic cylinder to drive the arc-pressing plate 35 to perform downward or upward movements.

[0050] An arc-pressing plate 35 is installed at the drive end of the lifting assembly 33 and is used to apply downward pressure to the profile to achieve arc pressing. A mounting base 331 for mounting the arc-pressing plate 35 is provided below the lifting assembly 33. Two connecting plates 332 are fixedly connected to the bottom side of the mounting base 331 near both ends. The two ends of the arc-pressing plate 35 are hinged to the two connecting plates 332 respectively.

[0051] The arc-pressing plate 35 has an adjustment assembly 36 for adjusting the curvature on its arc-shaped inner wall near both ends. The adjustment assembly 36 includes a tension rod 361 fixedly connected to the inner wall of the arc-pressing plate 35, an adjustment screw 362 movably connected to the tension rod 361, and an adjustment bolt 363 cooperating with the adjustment screw 362. In this embodiment, two sets of tension rods 361 and adjustment screws 362 are symmetrically arranged, and both adjustment screws 362 are threadedly connected to the adjustment bolt 363. By rotating the adjustment bolt 363, the operator can move the two tension rods 361 closer to each other or further apart, thereby fine-tuning the effective working radius of the arc-pressing plate 35 to adapt to the arc-pressing requirements of different curvature radii.

[0052] To ensure the accuracy and safety of the arc forming process, a limit valve 37 is provided on one side of the column 32, which cooperates with the lifting assembly 33. The limit valve 37 can be a limit switch or an encoder, used to precisely control the pressing height of the arc plate 35 and prevent overpressure damage to the mold or profile.

[0053] Reference Figure 9 and Figure 10The arc-pressing track 34 is mounted on the base 31 and is used to support the profile to be pressed. In this embodiment, the arc-pressing track 34 is symmetrically arranged on both sides of the base 31, supporting the two ends of the profile to be pressed. The arc-pressing track 34 and the base 31 are installed by a rotatable connection, thus having a degree of rotational freedom. A hinge seat 341 is fixedly connected to the bottom side of the arc-pressing track 34, and a shaft 311 is provided on the base 31 for rotatably connecting the hinge seat 341. The length direction of the shaft 311 is perpendicular to the length direction of the arc-pressing track 34, and a support block 312 for supporting the bottom of the arc-pressing track 34 is fixedly connected to the shaft 311 at the middle position. The two support blocks 312 are symmetrically provided with guide arc surfaces 313 on their close sides for guiding the rotation of the arc-pressing track 34.

[0054] The base 31 is equipped with an adjusting screw 314 and a handwheel 315 for driving the shaft 311 to rotate. A scale 316 for marking the adjustment position of the shaft 311 is provided on one side of the base 31. By querying a preset database, the operator can directly obtain the correspondence between the profile length and the bending radius, as well as the correspondence with the position of the shaft 311. Therefore, by precisely adjusting the shaft 311 using the scale 316, the tilt angle of the arc-pressing track 34 can be adjusted to adapt to processing requirements of different curvatures.

[0055] To accommodate profiles of different lengths, a sliding seat 342 is slidably mounted on the arc-pressing track 34. The sliding seat 342 can slide and adjust along the length of the arc-pressing track 34. A pad 343 is detachably connected to the sliding seat 342, and the pad 343 has a groove on its top side that matches the profile. A limiting rod 344 is fixedly connected to one side of the pad 343. The limiting rod 344 extends along the length of the pad 343 and has a limiting piece 345 for abutting the end of the profile. The limiting piece 345 ensures the axial positioning of the profile during the arc-pressing process. The limiting rod 344 passes through the limiting piece 345 and is detachably connected to the limiting piece 345 by threads or snaps.

[0056] To absorb stress during the arc pressing process and achieve automatic reset, two arc pressing tracks 34 are each fixedly connected to a first reset spring 346 at their opposite ends, with the other end of the first reset spring 346 fixedly connected to the base 31. When the lifting assembly 33 drives the arc pressing plate 35 to press down, the profile is subjected to force that is transmitted to the arc pressing track 34. The arc pressing track 34 rotates around the shaft 311, and the first reset spring 346 is stretched and stores energy. After processing is completed, the lifting assembly 33 is raised, and the restoring force of the first reset spring 346 drives the arc pressing track 34 to reset.

[0057] Two limiting plates 345 clamp the profile. During the arc pressing process, both ends of the profile abut against the two limiting plates 345 respectively, thereby forcing the pad 343 to drive the sliding seat 342 to slide relative to each other on the arc pressing track 34, absorbing the thrust generated by the extension of the profile. A second return spring 347 is fixedly connected to the end of the sliding seat 342 away from the limiting plates 345, and the other end of the second return spring 347 is fixedly connected to the arc pressing track 34, so that the sliding seat 342 is reset after processing.

[0058] The implementation principle of a shower room track arc pressing device according to an embodiment of this application is as follows: The device consists of a filling mechanism 1, a padding mechanism 2, an arc pressing mechanism 3, and a turnover mechanism 4 working together. First, the turnover mechanism 4 clamps the profile and moves it through various workstations. The filling mechanism 1 forms a dual-workstation through two sets of filling components 12, injecting nylon and other supporting materials into the profile. The sealing component 15 uses an automatic tape slitting machine 151 to cut and seal both ends of the profile to prevent material leakage. The padding mechanism 2 uses a lifting drive component 211 and a pressing drive component 221 to precisely fasten the upper and lower pads to the surface of the profile, protecting the profile from scratches during arc pressing. In the arc pressing mechanism 3, the lifting component 33 drives the arc pressing plate 35 to press down, and the double-headed adjusting bolt 363 can finely adjust the curvature of the arc pressing plate 35. The arc pressing track 34 is adjusted by the shaft 311 and positioned by the scale 316 to achieve angle adaptation. The sliding seat 342, the pad block 343, and the double return spring system absorb deformation stress and ensure clamping stability and automatic reset. The turnover mechanism 4 achieves precise transfer and attitude adjustment through the X / Z axis module and servo rotation drive 44. The various mechanisms can be linked through preset programs to form a closed-loop process of filling, padding, and arc pressing. Combined with adjustable mechanisms and precision sensor control, it meets the flexible and high-precision arc pressing requirements of different specifications of profiles.
