Description

Technical Field

[0001] This application relates to the field of extrusion molding technology, specifically to an outlet shaping device for a high-quality ultra-wide aluminum alloy sheet extrusion press. Background Technology

[0002] Aluminum alloy extrusion and uneven cooling can generate residual stress in the cross section. Over time, this stress can lead to warping, springback, or twisting. Shaping (such as stretching and annealing) can release or redistribute these stresses to stabilize dimensions.

[0003] CN223847789U discloses a floating forming mechanism for aluminum alloy profiles and an online forming fixture at the mold exit. In this mechanism, the bottom surface of the upper slider mates with the inclined top surface of the upper slider drive block, and the bottom surface of the lower slider drive block mates with the inclined top surface of the lower slider. An elastic element for driving the lower slider upwards is connected between the mounting base and the lower slider. This mechanism can form aluminum alloy profiles of different thicknesses, offering good versatility. Furthermore, when forming resistance is excessive, the upper and lower sliders can adaptively move upwards and downwards respectively to avoid bending or twisting of the aluminum alloy profile wall. Simultaneously, the floating forming mechanism adopts an integrated mounting structure centrally mounted on the mounting base, simplifying the assembly process and improving the overall structural strength and stability.

[0004] Extra-wide aluminum alloy sheets are more prone to twisting during extrusion:

[0005] The wide cross-section leads to more significant flow unevenness: the metal flow rate, friction and temperature gradient at different transverse positions in the mold are more likely to be different in the wide cross-section. After demolding, the longitudinal elongation of each zone is inconsistent and is released by torsion or warping.

[0006] Uneven cooling amplifies shrinkage differences: When ultra-wide parts are cooled, the heat dissipation conditions at the edges and in the middle are different. The uneven temperature field will generate asymmetric residual stress in the transverse and longitudinal directions, which will then manifest as twisting.

[0007] Increased difficulty in traction and guidance: Ultra-wide profiles require a wider and more uniform traction and guidance system. If the guidance is insufficient or the tension distribution is uneven, it will allow free rotation or lateral displacement, resulting in twisting.

[0008] At present, the effect of rolling on torsion is limited. Torsion is an angular displacement within a cross section. Simple longitudinal rolling (planar straightening) is difficult to completely eliminate torsion. It is necessary to generate a reverse torque on the cross section or apply torsion constraints to correct it. Ordinary rolling mainly applies bending moment rather than torque, so its ability to correct torsion is limited. Summary of the Invention

[0009] In view of this, the embodiments of this application aim to provide a high-quality ultra-wide aluminum alloy sheet extrusion press outlet shaping device. This device utilizes a detection unit to perform contact detection on the upper and lower surfaces of the sheet, multiple eccentric torsion wheels in a torsion unit to achieve adaptive fitting and shaping of warped or twisted areas, and symmetrical transmission and meshing components to achieve driving, positioning, and resetting. This enables stable online detection and shaping under high-speed conveying conditions. It features modular structure, rapid response, adaptability to wide sheet materials, and supports multiple alternative implementations to suit different working conditions.

[0010] To achieve the above objectives, the first aspect of this application provides: a high-quality ultra-wide aluminum alloy sheet extrusion press outlet shaping device, comprising:

[0011] Mounting rack;

[0012] The detection unit contacts the upper and lower parts of the aluminum alloy sheet;

[0013] A torsion section is located at the rear end of the detection section. The torsion section is provided with multiple torsion wheels, which contact the upper and lower parts of the aluminum alloy sheet.

[0014] The driving component connects the detection unit and the torsion unit;

[0015] The torsion section is provided with a rotating shaft connected to the mounting frame. The rotating shaft can drive the torsion wheel to rotate relative to the mounting frame, and the torsion wheel can be offset relative to the axis of the rotating shaft.

[0016] The detection unit contacts the upper and lower parts of the aluminum alloy plate and feeds back to the torsion unit through the driving component. The driving component switches the driving posture outside the detection unit, and the torsion wheel is driven by the driving component to generate an axial offset due to the change in the driving posture.

[0017] In some embodiments, the detection unit includes a positioning frame, a guide rod, an elastic element, and a contact. The positioning frame is disposed inside the mounting frame, and the positioning frame has an insertion hole along a second direction. The guide rod is inserted into the insertion hole and is coaxially disposed with the insertion hole.

[0018] The contact is located on the side of the guide rod facing the aluminum alloy plate and contacts the upper and lower parts of the aluminum alloy plate. The elastic element is located inside the socket and supports the guide rod so that the contact abuts against the aluminum alloy plate.

[0019] In some embodiments, the drive member is configured with a first transmission part and a second transmission part, the first transmission part and the second transmission part are arranged symmetrically above and below each other, the first transmission part and the second transmission part are provided with a plurality of meshing members, the meshing members meshing with the guide rod and the torsion part;

[0020] When the meshing member engages the torsion part, the driving member is in a torsion posture. Both the first transmission part and the second transmission part are provided with a reset wheel. When the reset wheel is connected to the meshing member, the meshing member is reset.

[0021] In some embodiments, both the first transmission part and the second transmission part are provided with a transmission roller, a transmission belt, and a drive motor. The transmission roller is installed inside the mounting frame and can rotate relative to the mounting frame. The transmission belt is sleeved on the outside of the transmission roller and driven by the transmission roller. The output end of the drive motor is connected to the transmission roller.

[0022] The transmission speed of the transmission belt is consistent with the conveying speed of the aluminum alloy sheet.

[0023] In some embodiments, the end of the guide rod away from the aluminum alloy plate extends through the positioning frame to the outside of the positioning frame. The engaging component includes a mounting base, a sliding plate, a first electromagnetic component, a second electromagnetic component, and a limiting top rod. The first electromagnetic component and the second electromagnetic component each include an active magnet mounted on the guide rod and a passive magnet mounted on the sliding plate, and the active magnets of the first electromagnetic component have opposite magnetic poles.

[0024] The mounting base is installed on the inner side of the transmission belt, and the slide plate is slidably installed inside the mounting base, sliding under the drive of the first electromagnetic component and the second electromagnetic component.

[0025] In some embodiments, the limiting rod is installed inside the mounting base, and the telescopic end of the limiting rod supports the slide plate after the first electromagnetic component and the second electromagnetic component drive the slide plate to slide, so that the slide plate is limited.

[0026] In some embodiments, the torsion part includes a pressure plate, a limiting frame, and a buffer member. The limiting frame is embedded inside the mounting frame and can move up and down relative to the mounting frame. The limiting frame is engaged with the torsion wheel, and the buffer member is disposed inside the limiting frame and contacts the torsion wheel.

[0027] The length of the pressure plate is between the closest distance between adjacent sliding plates and the center distance between adjacent sliding plates.

[0028] In some embodiments, the buffer includes an elastic wheel, which is mounted inside the limiting frame and contacts the torsion wheel.

[0029] In some embodiments, a slide is provided inside the mounting bracket, the slide is embedded in the mounting bracket and can slide relative to the mounting bracket, and the rotating shaft is embedded in the slide and can rotate relative to the slide;

[0030] The mounting bracket is provided with a telescopic component on its outer side. The telescopic component is connected to the slide and can push the slide to slide.

[0031] In some embodiments, the carriage is configured to slide on one side or both sides, and the tilt angle of the carriage when sliding on one side is 0-5°.

[0032] This solution achieves online, continuous, and rapid warping and twisting detection and local shaping of ultra-wide aluminum alloy sheets through the coordinated work of the detection and torsion sections, the adaptive fit of the eccentric torsion wheel, the symmetrical synchronous drive, and the limitable meshing structure. It can maintain detection sensitivity and shaping repeatability under high-speed conveying, while also applying force evenly, absorbing impact and protecting the sheet surface, reducing manual intervention and rework rate, and improving sheet flatness, production yield, and production line uptime.

[0033] Single-sided sliding allows for controllable displacement and small-angle tilting of the carriage and shaft on one side, enabling fine adjustment of the contact point and contact angle of the torsion wheel. This allows for targeted shaping of locally warped or twisted areas, improving the flexibility and specificity of local shaping, enhancing fit, and dispersing shaping force to reduce stress concentration and surface damage risks. It also facilitates online fine-tuning for rapid response to detection signals, expanding the device's adaptability to different plate widths and defect morphologies, and improving shaping success rate and production line stability.

[0060] In related technologies, aluminum alloy extrusion and uneven cooling can generate residual stress in the cross section. The release of stress over time can lead to warping, springback, or twisting. Shaping (such as stretching and annealing) can release or redistribute these stresses to stabilize dimensions.

[0061] Extra-wide aluminum alloy sheets are more prone to twisting during extrusion:

[0062] The wide cross-section leads to more significant flow unevenness: the metal flow rate, friction and temperature gradient at different transverse positions in the mold are more likely to be different in the wide cross-section. After demolding, the longitudinal elongation of each zone is inconsistent and is released by torsion or warping.

[0063] Uneven cooling amplifies shrinkage differences: When ultra-wide parts are cooled, the heat dissipation conditions at the edges and in the middle are different. The uneven temperature field will generate asymmetric residual stress in the transverse and longitudinal directions, which will then manifest as twisting.

[0064] Increased difficulty in traction and guidance: Ultra-wide profiles require a wider and more uniform traction and guidance system. If the guidance is insufficient or the tension distribution is uneven, it will allow free rotation or lateral displacement, resulting in twisting.

[0065] Rolling the sheet metal during the conveying process with rollers can shape the sheet metal and improve its quality. However, rolling is limited in its ability to correct torsion. Torsion is an angular displacement within a cross section, and simple longitudinal rolling (planar straightening) cannot completely eliminate torsion. It is necessary to generate a reverse torque on the cross section or apply torsional constraints to correct it. Ordinary rolling mainly applies bending moment rather than torque, so its ability to correct torsion is limited.

[0066] This application provides an outlet shaping device for a high-quality ultra-wide aluminum alloy sheet extrusion press. (See attached document.) Figure 1-3 and Figure 7 As shown, the device includes a mounting frame 100, a detection unit 200, a torsion unit 300, and a drive unit 400. The mounting frame 100 serves as the overall support and mounting reference. The torsion unit 300 is located at the rear end of the detection unit 200 and is connected to the mounting frame 100 via a rotating shaft 11. The rotating shaft 11 drives multiple torsion wheels 31 to rotate relative to the mounting frame 100, and each torsion wheel 31 can be offset relative to the axis of the rotating shaft 11. The detection unit 200 is located at the front end of the torsion unit 300 and contacts the upper and lower parts of the aluminum alloy sheet via a contact 24. The displacement or contact force of the detection unit 200 is fed back to the torsion unit 300 through the drive unit 400. The drive unit 400 switches the driving posture outside the detection unit 200 to change the driving state of the torsion wheels 31 and generate an axis offset, thereby achieving adaptive fitting and shaping of warped or twisted parts. This structure can automatically adjust the contact position and eccentricity of the torsion wheel 31 when the sheet material warps or twists, so as to achieve adaptive shaping of local unevenness and maintain the continuity and stability of the shaping process.

[0067] It achieves an integrated response of detection, driving, and shaping, enabling rapid adaptive compensation for local warping under high-speed conveying conditions, reducing manual intervention and rework, and improving the flatness of the sheet and the stability of the production cycle.

[0068] See Figure 3 As shown, the detection unit 200 consists of a positioning frame 21, a guide rod 22, an elastic element 23, and a contact 24. The positioning frame 21 is located inside the mounting frame 100 and has insertion holes arranged along the second direction. The guide rod 22 is inserted into the insertion holes and is coaxial with the insertion holes. The contact 24 is located on the side of the guide rod 22 facing the plate and always abuts against the upper and lower surfaces of the plate under the action of the elastic element 23. The end of the guide rod 22 away from the plate extends through the positioning frame 21 to the outside so as to engage with the engaging element 43 or connect with the driving element 400. This detection structure can continuously collect changes in displacement or force in an elastic contact manner when the plate surface is deformed, ensuring detection sensitivity and long-term contact stability, thereby providing reliable real-time input for subsequent shaping operations.

[0069] It provides highly sensitive and continuous contact detection capabilities, accurately reflecting the instantaneous warping and twisting state of the board, providing timely and reliable trigger signals for the shaping action, and reducing the false judgment and missed detection rate.

[0070] See Figure 3 and Figure 6-7 As shown, the driving component 400 consists of a first transmission part 41 and a second transmission part 42, which are symmetrically arranged vertically. These two parts correspond to the upper and lower parts of the sheet material, respectively, and engage with the guide rod 22 and the torsion part 300 through several meshing parts 43. The transmission part may include a transmission roller 10, a transmission belt 20, and a drive motor 30. The transmission roller 10 is mounted inside the mounting frame 100 and can rotate relative to the mounting frame 100. The transmission belt 20 is sleeved on the outside of the transmission roller 10 and driven by the transmission roller 10. The transmission speed of the transmission belt 20 is consistent with the sheet material conveying speed to achieve synchronous driving. This transmission and meshing layout can quickly transmit the driving force to the meshing parts 43 and drive the torsion part 300 when torsion is detected. Simultaneously, the symmetrical design achieves synchronous action on the upper and lower surfaces of the sheet material, ensuring a balanced distribution of shaping force and consistent shaping effect.

[0071] It enables power transmission synchronized with the sheet material conveying and synchronous shaping of the upper and lower surfaces, avoiding new deformations caused by uneven force on different sides, and improving shaping uniformity and finished product consistency.

[0072] See Figure 6-7 The meshing component 43 shown includes a mounting base 431, a sliding plate 432, a first electromagnetic component 433, a second electromagnetic component 434, and a limiting rod 435. The mounting base 431 is installed inside the transmission belt 20. The sliding plate 432 can slide within the mounting base 431. The first electromagnetic component 433 and the second electromagnetic component 434 are respectively composed of an active magnet 436 installed at the guide rod 22 and a passive magnet 437 installed at the sliding plate 432. The polarities of the active magnet 436 of the first electromagnetic component 433 and the active magnet 436 of the second electromagnetic component 434 can be designed to be opposite to achieve attraction or repulsion. Driven by the electromagnetic components, the sliding plate 432 slides and meshes with the guide rod 22. After the sliding plate 432 is in place, the limiting rod 435 extends to support the sliding plate 432 to achieve mechanical limiting. The transmission part is also provided with a reset wheel 44 to reset the meshing component 43 when the drive is released. This engagement and limiting combination enables rapid and controllable engagement and release, and provides rigid support after the slide plate 432 is in place, ensuring the positioning accuracy and repeatability of the torsion part 300 during the shaping process.

[0073] Achieving rapid-response engagement and reliable mechanical limiting ensures that the speed of action switching can adapt to the production cycle, while providing rigid support during the shaping stage to ensure the repeatability accuracy of the shaping position and force, and reduce the impact of positioning errors on the shaping quality.

[0074] See Figure 10-13The torsion section 300 further includes a pressure plate 32, a limiting frame 33, and a buffer 34. The limiting frame 33 is embedded inside the mounting frame 100 and can move up and down relative to the mounting frame 100. The limiting frame 33 is engaged with the torsion wheel 31. The pressure plate 32 is connected to the limiting frame 33 and is associated with the center distance of the adjacent slide plate 432. The buffer 34 is disposed inside the limiting frame 33 and contacts the torsion wheel 31. The buffer 34 is preferably an arc-shaped elastic wheel to achieve stable contact with the torsion wheel 31 and absorb impact. When the slide plate 432 pushes the pressure plate 32 and the limiting frame 33 to move, the limiting frame 33 applies a controlled compressive force to the torsion wheel 31. The buffer 34 buffers the impact and evenly distributes the contact pressure during the force application process, thereby providing sufficient forming force during shaping and protecting the torsion wheel 31 and the surface of the sheet material from localized damage.

[0075] By combining limiting and buffering, controlled extrusion and impact absorption are achieved, which can provide effective shaping force to correct warping, protect the torsion wheel 31 and the surface of the sheet, reduce surface damage and equipment wear, and extend service life.

[0076] The cooperation between the guide rod 22 and the slot, the design of the contact 24 and the elastic element 23, and the meshing interface extending from the back of the guide rod 22 enable the detection unit 200 to maintain continuous contact with the surface of the plate and reliably transmit displacement or force signals to the meshing element 43 even under high-speed conveying conditions. This detection-meshing coupling method can achieve a rapid response to plate warping and trigger corresponding shaping actions, thereby reducing the accumulation of instantaneous deformation of the plate during the conveying process and improving shaping efficiency.

[0077] To ensure the stability of detection and the reliability of signal transmission under high-speed production conditions, achieve rapid closed-loop shaping response, reduce deformation accumulation and defect rate, and improve the overall yield of the production line.

[0078] See Figure 8-9 As shown, the rotating shaft 11 is embedded inside the carriage 12 and can rotate relative to the carriage 12. The carriage 12 is embedded inside the mounting frame 100 and can slide relative to the mounting frame 100. The mounting frame 100 has a telescopic member 13 on its outer side that connects to the carriage 12 to push the carriage 12 to slide. The carriage 12 can be designed to slide on one side or both sides. When sliding on one side, a tilt angle of 0–5° is allowed to change the contact position between the rotating shaft 11 and the torsion wheel 31. By driving the carriage 12 to slide and changing the position or tilt angle of the rotating shaft 11 through the telescopic member 13, the contact point and contact angle of the torsion wheel 31 can be adjusted in the longitudinal or transverse direction, thereby adapting to different widths of plates or different shapes of warped / twisted parts, and achieving more precise local shaping.

[0079] Unilateral sliding causes the contact point between the pivot and the torsion wheel relative to the board to move longitudinally or laterally, thereby enabling precise shaping of local warped or twisted areas. Unilateral sliding produces a 0–5° tilt, allowing the torsion wheel to act on the board surface at different incident angles, improving the fit to complex curvatures or local unevenness.

[0080] By combining local displacement and tilting, multi-point and segmented shaping can be achieved without changing the overall layout of the machine, reducing interference with the overall mechanism. The tilted contact and adjustable position help to disperse the shaping force and avoid surface damage or new stress concentration caused by single-point overpressure.

[0081] Adaptable to different plate widths and defect morphologies: Single-sided sliding expands the device's adaptability to different widths and warp shapes, improving the targeting and success rate of shaping.

[0082] The adjustable position and angle of the pivot 11 expand the adaptability of the shaping device, enabling precise shaping of warps of different widths and shapes, and improving the flexibility and specificity of the shaping process.

[0083] The coordination of the transmission belt 20, transmission roller 10, drive motor 30 and tensioning device, as well as the mechanical limiting design of the buckling and reset wheel 44 and the limiting rod 435, ensure synchronous transmission, reliable meshing and rapid reset at continuous production line speeds. The synergistic effect of these mechanisms enables the shaping device to complete the detection and shaping actions without affecting the production cycle, thereby improving the overall stability and capacity utilization of the production line.

[0084] While ensuring synchronous operation with the production line, it achieves reliable action switching and rapid reset, avoiding the impact of shaping actions on the production line cycle time and improving production line utilization and production efficiency.

[0085] To adapt to different working conditions and maintenance needs, this application also provides several alternative implementation schemes: the shaft offset of the torsion wheel 31 can be achieved by using an eccentric sleeve, an eccentric pin, or an electric fine-tuning eccentric mechanism; the electromagnetic drive of the meshing component 43 can be replaced by a mechanical cam or a pneumatic clamping mechanism to adapt to high temperature or strong interference environments; the material of the elastic buffer 34 can be selected from polyurethane, silicone, or a metal elastic composite to balance wear resistance and resilience; the telescopic component 13 can be equipped with a servo screw, hydraulic cylinder, or pneumatic cylinder to meet different thrust and response speed requirements; the transmission belt 20-transmission roller 10 system can be replaced by a rack and pinion direct drive or dual drive parallel connection to improve rigidity and long stroke stability.

[0086] Those skilled in the art can use alternative solutions to optimize cost, reliability, and control precision under different production line conditions.

[0087] The shaping steps for extra-wide aluminum alloy sheets are as follows:

[0088] Fix the mounting bracket to the extruder outlet and calibrate the reference position, confirming that the mounting bracket is coaxial with the production line and that all supports are secure.

[0089] Check and adjust the initial positions of the pivot, torsion wheel, limit frame and carriage to ensure that the torsion wheel is in a non-contact standby state.

[0090] The contact of the detection unit is installed into the positioning frame and the preload of the elastic element is adjusted so that the contact extends slightly when there is no plate to ensure contact sensitivity.

[0091] Start the conveyor and feed the specimen in at a low speed. Observe the contact between the contact and the upper and lower surfaces of the plate and record the initial displacement or force value.

[0092] Synchronize the transmission unit (transmission roller / transmission belt) with the production line speed, and confirm that the transmission belt tension and the reset wheel are working properly.

[0093] When the contact displacement or force value exceeds the preset threshold, the drive unit causes the engagement plate to slide within the mounting base and engage with the guide rod.

[0094] Once the slide plate is in position, the limit rod extends to mechanically limit the slide plate, ensuring engagement rigidity and preparing to drive the torsion section.

[0095] After engagement, the drive torsion section shaft drives the torsion wheel to rotate and generates axial offset through the eccentric or offset mechanism, applying controlled extrusion force to the plate locally.

[0096] When the torsion wheel contacts the limit frame / pressure plate, the buffer (elastic wheel) absorbs the impact and distributes the contact pressure evenly, continuously reshaping until the contact feedback returns to the allowable range.

[0097] If it is necessary to change the shaping position or angle, activate the telescopic component to push the carriage to slide or tilt (0–5° on one side), and adjust the position of the pivot to reposition the contact point of the torsion wheel.

[0098] After the shaping is completed, the electromagnetic or mechanical engagement is released, the reset wheel resets the slide plate, the limit rod retracts, and the torsion wheel returns to its standby position.

[0099] The shaped boards are tested and verified online or offline (flatness / warping). If they do not meet the standards, the fine-tuning is repeated.

[0100] The above embodiments are merely illustrative of the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
