Description

Technical Field

[0001] This invention belongs to the field of aluminum profile production technology, specifically referring to an aluminum profile extrusion molding equipment. Background Technology

[0002] In the continuous extrusion molding process of aluminum profiles, after the extruder completes the profile forming, the last section of the profile needs to be completely led out of the extrusion die to avoid residual material from causing die cavity blockage or affecting the starting quality of the next extrusion. Currently, an independently set clamping and pulling mechanism is commonly used to clamp the formed profile during the extrusion stroke and apply tension along the extrusion direction, working in conjunction with the conveyor roller group to achieve continuous traction and fixed-length cutting of the profile.

[0003] To avoid spatial interference between the movement trajectory of the clamping and pulling mechanism and the fixed-position conveyor roller, existing designs typically place the clamping and pulling mechanism above the conveyor roller and apply an upward lifting force to the profile while it is clamped, lifting the profile off the roller surface before axial traction is applied. This operation causes the profile to lose continuous support from the conveyor roller in the clamping section, relying only on local forces at the clamping point to maintain its posture. Under the coupled action of tension and its own weight, it is prone to bending deformation or cross-sectional distortion. Especially for thin-walled, wide, or high aspect ratio profiles, its straightness and dimensional stability are significantly reduced, affecting the accuracy and consistency of subsequent straightening, sawing, and assembly processes. Summary of the Invention

[0004] In view of the above situation and to overcome the defects of the prior art, the purpose of the present invention is to provide an aluminum profile extrusion forming equipment to at least partially solve the problems of lack of support, easy deformation and poor dimensional accuracy in the profile traction process mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: The present invention proposes an aluminum profile extrusion forming equipment, comprising: The extruder body has an extrusion head on one side for extruding aluminum rods into aluminum profiles; The conveyor rollers are installed at the end of the extruder body where the extrusion head is located, and are used to support and smoothly convey the extruded aluminum profiles. The movable conveying module has at least two sets arranged in the middle section of the conveying roller line along the conveying direction of the aluminum profile; the movable conveying module includes a support roller group and a lifting drive unit, and the support roller group is driven by the lifting drive unit to switch between a descending avoidance state and an ascending support state. The clamping and pulling mechanism includes a clamp for clamping and pulling aluminum profiles and a motion transmission component. The clamp is configured to reciprocate along the aluminum profile extrusion conveying direction to completely pull the end residue of the aluminum profile out of the extruder body and complete the residue cleaning. The motion transmission component is configured to move synchronously with the clamp and is rigidly linked with the lifting drive unit during the movement. When the clamping and pulling mechanism moves the aluminum profile along the extrusion direction through the clamps and passes through the area where the support roller group is located, the motion transmission component triggers the lifting drive unit, driving the support roller group to synchronously descend to the avoidance position to disengage from the bottom support path of the aluminum profile. After the clamping and pulling mechanism moves out of this area, the support roller group automatically rises to the working position under the linkage of the motion transmission component and the lifting drive unit, re-adhering to the bottom surface of the aluminum profile to provide continuous support. Through the above actions, the switching between the descending avoidance and rising support states of the support roller group is realized. During the switching between the descending avoidance and rising support states, the support roller group always ensures that there is at least one effective support point for the aluminum profile within the clamping and pulling path, thereby eliminating bending deformation and cross-sectional distortion caused by support interruption.

[0006] Furthermore, the lifting drive unit includes a roller frame, a drive shaft, and a cam. Multiple sets of parallel rollers are evenly arranged on the roller frame, and the rollers are in contact with the bottom surface of the aluminum profile to achieve stable conveying and support. The drive shaft is horizontally rotatable on the equipment frame below the roller frame. The cam is fixedly sleeved on the drive shaft and located directly below the roller frame. The outer contour surface of the cam is always tangentially in contact with the lower surface of the roller frame. A drive gear is fixedly provided at the end of the drive shaft, and a drive rack matching the drive gear is fixedly provided on the motion transmission component.

[0007] Furthermore, the drive rack is symmetrically provided with two sets at both ends of the motion transmission component, which correspond one-to-one with the drive gears on the drive shafts of the two sets of support rollers that are about to pass and those that have already passed, respectively, to control the descent of the support rollers that are about to pass and the rise and reset of the support rollers that have already passed.

[0008] Furthermore, multiple sets of support components are symmetrically arranged below the roller frame. Each support component includes a support cylinder, a support slide rod, and a support spring. The support cylinder is fixed to the equipment frame, and the support slide rod is vertically slidably disposed inside the support cylinder. The upper end of the support slide rod is fixedly connected to the bottom of the roller frame. The support spring is sleeved on the outside of the support cylinder and the support slide rod. The lower end of the support spring is fixedly connected to the bottom end of the support cylinder, and the upper end is connected to the bottom of the roller frame.

[0009] Furthermore, the clamp includes a lower clamping plate and an upper clamping plate arranged opposite each other. The lower clamping plate is used to stably support the bottom of the aluminum profile, and the upper clamping plate can be raised and lowered vertically to cooperate with the lower clamping plate to clamp the upper and lower end faces of the aluminum profile.

[0010] Furthermore, the clamping and pulling mechanism also includes an adjustment box, which contains a linkage mechanism. A first sliding plate and a second sliding plate are vertically slidable through the top wall of the adjustment box. Both the first and second sliding plates are connected to the linkage mechanism and driven by the linkage mechanism to achieve reverse synchronous lifting and lowering actions. The upper end of the first sliding plate is fixedly connected to a support guide roller for auxiliary support of the aluminum profile, and the upper end of the second sliding plate is fixedly connected to the lower clamping plate. When the first sliding plate drives the support guide roller to descend and avoid a collision, the second sliding plate synchronously drives the lower clamping plate to rise, cooperating with the upper clamping plate to complete the clamping of the aluminum profile and achieve profile traction. When the first sliding plate drives the support guide roller to rise and support the profile, the second sliding plate synchronously drives the lower clamping plate to descend and release the profile. The support guide roller supports the profile in real time, filling the support gap after the clamp is released, and completely eliminating the unsupported suspended section of the profile.

[0011] Furthermore, the linkage mechanism includes a linkage drive screw, a guide slide, a drive block, and a linkage assembly. The linkage drive screw is horizontally rotatable inside the adjustment box. The guide slide is fixedly installed and parallel to the linkage drive screw. The drive block is connected to the linkage drive screw by a thread and is slidably sleeved on the guide slide, achieving smooth horizontal sliding by relying on the guide slide. The linkage assembly is hinged to the drive block, the first slide plate, and the second slide plate for transmission.

[0012] Furthermore, the linkage component includes a first link and a second link. One end of the first link is hinged to the drive block, and the other end is hinged to the bottom end of the first slide plate. One end of the second link is hinged to the middle of the first link, and the other end is hinged to the bottom end of the second slide plate, forming a lever-type linkage transmission structure.

[0013] Furthermore, the outer wall of the regulating box is rotatably provided with a horizontally arranged drive shaft. The inner end of the drive shaft extends into the regulating box and is fixedly provided with a driving bevel gear. The middle part of the linkage drive screw is fixedly sleeved with a driven bevel gear. The driving bevel gear and the driven bevel gear mesh vertically for transmission. The outer end of the drive shaft outside the regulating box is fixedly provided with a linkage gear. The outer walls of the roller frames of the support roller groups at both ends are fixedly provided with linkage racks. The linkage gear can move horizontally synchronously with the regulating box and can automatically mesh with the linkage racks for transmission during the movement.

[0014] Furthermore, the two ends of the drive block and the linkage drive screw are connected by two sets of threaded segments with opposite directions. The linkage components are respectively provided in two sets corresponding to the drive block. The support guide rollers are symmetrically provided in two sets on both sides of the lower clamping plate. The first connecting rods of the two sets of linkage components are respectively hinged to the two sets of first sliding plates. The second connecting rods of the two sets of linkage components are both hinged to the second sliding plates, thereby driving the two sets of support guide rollers to rise and fall.

[0015] Furthermore, the clamping and pulling mechanism also includes a pulling screw, a pulling guide rod, a pulling motor, and a mounting bracket. The pulling screw is horizontally rotatably mounted on the equipment frame, and one end of the pulling screw is fixedly connected to the output shaft of the pulling motor. The pulling guide rod is fixedly parallel to the side of the pulling screw. The mounting bracket is threadedly connected to the pulling screw via a threaded seat, and the mounting bracket is slidably sleeved on the pulling guide rod. The adjusting box is fixedly installed in the middle of the mounting bracket and moves synchronously with the mounting bracket. A lifting cylinder is fixedly installed on the top of the mounting bracket, and the upper clamping plate is fixedly connected to the telescopic end of the lifting cylinder.

[0016] Furthermore, several cooling fans are evenly installed on the conveyor roller line; the conveyor roller line includes a first conveyor roller line and a second conveyor roller line connected front to back, and multiple sets of movable support modules are arranged at intervals in the connection gap between the first conveyor roller line and the second conveyor roller line; a cutting mechanism is assembled at the end of the second conveyor roller line.

[0017] The technical solution provided by this invention has the following beneficial effects: (1) By adding two sets of movable conveying modules that can be raised and lowered in the middle of the conveying roller line and coordinating with the movement of the clamping and pulling mechanism, the movable conveying module actively lowers to avoid the movement path of the clamp, and then rises and resets after the clamp passes through, so that the aluminum profile can always be supported by the roller body during the entire process of clamping and pulling and the residual material being pulled out.

[0018] (2) This solution effectively avoids the situation of the profile being suspended without support during the traction process, reduces the bending, deformation and cross-sectional distortion caused by the tension and self-weight of the profile, and effectively improves the forming quality of aluminum profiles. It is especially suitable for the production and processing of easily deformable profiles such as thin-walled and wide profiles. Attached Figure Description

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection.

[0023] In the description of the embodiments, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the embodiments and simplifying the description, and do 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, they should not be construed as limitations on the embodiments.

[0024] See Figure 1In this embodiment, the present invention provides an aluminum profile extrusion molding equipment, including an extruder body 1, a conveyor roller line, a movable conveying module 3, and a clamping and pulling mechanism. An extrusion head 2 is provided on one side of the extruder body 1 for extruding aluminum rods into aluminum profiles; the conveyor roller line is located at the end of the extruder body 1 where the extrusion head 2 is located, for supporting and smoothly conveying the extruded aluminum profile throughout the process; the movable conveying module 3 has at least two sets arranged in the middle section of the conveyor roller line along the aluminum profile conveying direction; the movable conveying module 3 includes a support roller group and a lifting drive unit, the support roller group being configured to be driven by the lifting drive unit to switch between a descending avoidance state or an ascending support state; the clamping and pulling mechanism includes a clamp for clamping and pulling the aluminum profile and a motion transmission component 4, the clamp being configured to reciprocate along the aluminum profile extrusion conveying direction to completely pull out the residual material at the end of the aluminum profile from the extruder body 1, completing the residual material cleaning, the motion transmission component 4 being configured to move synchronously with the clamp and rigidly linked with the lifting drive unit during the movement, driving the support roller group to rise or fall.

[0025] When the clamping and pulling mechanism moves along the extrusion direction and pulls the aluminum profile through the area where the support roller group is located, the motion transmission component 4 triggers the lifting drive unit to drive the support roller group to descend synchronously to the avoidance position to disengage from the bottom support path of the aluminum profile. After the clamping and pulling mechanism moves out of this area, the support roller group automatically rises to the working position under the linkage, re-adhering to the bottom surface of the aluminum profile to provide continuous support. Through the above actions, the switching between the descending avoidance and rising support states of the support roller group is realized. During the switching between the descending avoidance and rising support states, the support roller group always ensures that there is at least one effective support point for the aluminum profile within the clamping and pulling path, thereby eliminating bending deformation and cross-sectional distortion caused by support interruption.

[0026] Specifically, when the clamp drives the aluminum profile to move along multiple sets of support rollers in the aluminum profile conveying direction, one set of support rollers that is to be passed through is lowered to a low position in advance through the motion transmission component 4, completely avoiding the movement path of the clamp and the aluminum profile and eliminating spatial interference; when the clamp drives the aluminum profile to completely leave the coverage area of ​​the set of support rollers, the set of support rollers is reset and raised to a high position through the motion transmission component 4, adhering to the bottom of the aluminum profile to continuously support the profile, ensuring the continuity of conveying, and realizing that the aluminum profile is not suspended or detached from the support state throughout the entire traction process, thus avoiding the problems of profile bending and cross-sectional distortion from the root.

[0027] See Figures 3-5In this embodiment, the lifting drive unit includes a roller frame 5, a drive shaft 6, and a cam 7. Multiple sets of parallel rollers are evenly arranged on the roller frame 5, and the rollers are in contact with the bottom surface of the aluminum profile to achieve stable conveying and support. The drive shaft 6 is horizontally rotatably mounted on the equipment frame below the roller frame 5. The cam 7 is fixedly sleeved on the drive shaft 6 and located directly below the roller frame 5. The outer contour surface of the cam 7 is always tangentially in contact with the lower surface of the roller frame 5. When the drive shaft 6 rotates, it drives the cam 7 to rotate synchronously. The roller frame 5 is precisely driven to lift vertically by relying on the change in the contour height of the cam 7. A drive gear 8 is fixedly mounted at the end of the drive shaft 6. A drive rack 9 that matches the drive gear 8 is fixedly mounted on the motion transmission component 4. During the synchronous movement of the drive rack 9 with the clamp, it can automatically mesh with the drive gear 8 for transmission. The linkage control of lifting and lowering of the roller frame 5 can be achieved without an additional power source, resulting in higher structural synchronization and lower energy consumption.

[0028] See Figures 3-5 In this embodiment, two sets of drive racks 9 are symmetrically arranged at both ends of the motion transmission component 4, corresponding one-to-one with the drive gears 8 on the drive shafts 6 of the two sets of support rollers that are about to pass and those that have already passed, respectively. This controls the descent of the support rollers that are about to pass and the rise and reset of the support rollers that have already passed. As the motion transmission component 4 moves along with the clamping and pulling mechanism, the drive racks 9 and drive gears 8 at the corresponding positions gradually mesh and transmit power. The drive gears 8 drive the drive shafts 6 and cams 7 to rotate synchronously, precisely matching the clamping and traction position of the fixture to switch the lifting and lowering state of the support rollers. This ensures that the profile traction path and the support path are matched in real time, completely avoiding mechanical interference and ensuring that the profile has roller support at any traction position.

[0029] See Figures 3-5 In this embodiment, multiple sets of support components 10 are symmetrically arranged below the roller frame 5. Each support component 10 includes a support cylinder, a support slide rod, and a support spring. The support cylinder is fixed to the equipment frame, and the support slide rod is vertically slidably disposed inside the support cylinder. The upper end of the support slide rod is fixedly connected to the bottom of the roller frame 5. The support spring is sleeved on the outside of the support cylinder and the support slide rod. The lower end of the support spring is fixedly connected to the bottom end of the support cylinder, and the upper end is connected to the bottom of the roller frame 5. During the process of the cam 7 driving the roller frame 5 to rise and fall, the roller frame 5 drives the support slide rod to slide vertically along the support cylinder. At the same time, the support spring synchronously stretches and deforms. Through the elastic support of the support spring, the impact of the self-weight of the roller frame 5 and the profile is offset, ensuring that the roller frame 5 rises and falls smoothly without jamming.

[0030] See Figure 3 and Figure 6In this embodiment, the clamp includes a lower clamping plate 11 and an upper clamping plate 12 arranged opposite each other. The lower clamping plate 11 is used to stably support the bottom of the aluminum profile, and the upper clamping plate 12 can be raised and lowered vertically to cooperate with the lower clamping plate 11 to clamp the upper and lower end faces of the aluminum profile. The clamping surfaces of the clamping plates are provided with anti-slip and wear-resistant pads to increase the clamping friction and prevent the profile from slipping or being damaged during the traction process.

[0031] See Figure 6 In this embodiment, the clamping and pulling mechanism also includes an adjustment box 13. The adjustment box 13 is equipped with a linkage mechanism. A first sliding plate 14 and a second sliding plate 15 are vertically slidable through the top wall of the adjustment box 13. Both the first sliding plate 14 and the second sliding plate 15 are connected to the linkage mechanism and are driven by the linkage mechanism to achieve reverse synchronous lifting and lowering actions. The upper end of the first sliding plate 14 is fixedly connected to a support guide roller 16 for auxiliary support of the aluminum profile. The upper end of the second sliding plate 15 is fixedly connected to the lower clamping plate 11. When the first sliding plate 14 drives the support guide roller 16 to descend and avoid, the second sliding plate 15 synchronously drives the lower clamping plate 11 to rise, and cooperates with the upper clamping plate 12 to complete the clamping of the aluminum profile and realize the traction of the profile. When the first sliding plate 14 drives the support guide roller 16 to rise and support the profile, the second sliding plate 15 synchronously drives the lower clamping plate 11 to descend and release the profile. The support guide roller 16 supports the profile in real time, fills the support gap after the clamp is released, and completely eliminates the unsupported suspended section of the profile.

[0032] See Figure 6 In this embodiment, the linkage mechanism includes a linkage drive screw 17, a guide slide rod, a drive block 18, and a linkage assembly. The linkage drive screw 17 is horizontally rotatable inside the adjustment box 13. The guide slide rod is fixedly installed and parallel to the linkage drive screw 17. The drive block 18 is connected to the linkage drive screw 17 by a thread and is slidably sleeved on the guide slide rod, achieving smooth horizontal sliding by relying on the guide slide rod. The linkage assembly is hinged to the drive block 18, the first slide plate 14, and the second slide plate 15 for transmission.

[0033] See Figure 6 In this embodiment, the linkage component includes a first link 19 and a second link 20. One end of the first link 19 is hinged to the drive block 18, and the other end is hinged to the bottom end of the first slide plate 14. One end of the second link 20 is hinged to the middle of the first link 19, and the other end is hinged to the bottom end of the second slide plate 15, forming a lever-type linkage transmission structure. The two sets of slide plates can be accurately raised and lowered in opposite directions by simply rotating the linkage drive screw 17. The transmission structure is simple, the response speed is fast, and the action accuracy is high.

[0034] See Figure 3 and Figure 4In this embodiment, a horizontally arranged drive shaft 21 is rotatably provided on the outer wall of the regulating box 13. The inner end of the drive shaft 21 extends into the interior of the regulating box 13 and is fixedly provided with an active bevel gear. A driven bevel gear is fixedly sleeved in the middle of the linkage drive screw 17. The active bevel gear and the driven bevel gear mesh vertically for transmission. A linkage gear 22 is fixedly provided on the outer end of the drive shaft 21 outside the regulating box 13. A linkage rack 23 is fixedly provided on the outer wall of the roller frame 5 of the support roller group at both ends. The linkage gear 22 can move horizontally synchronously with the regulating box 13, and can automatically mesh with the linkage rack 23 for transmission during the movement.

[0035] After the clamping and pulling mechanism moves the adjusting box 13, the clamp, and the aluminum profile that is clamped and fixed, and completely pulls the residual material at the end of the aluminum profile out of the extruder body 1, the clamping and pulling mechanism moves to the support roller group at the tail end and continues to move forward a small preset distance. During this process, the linkage gear 22 and the linkage rack 23 mesh precisely. Relying on the characteristic that the rack is fixed, the linkage gear 22 is driven to rotate, which in turn drives the drive shaft 21 and the active bevel gear to rotate synchronously. Through the meshing transmission of the bevel gear, the linkage drive screw 17 is driven to rotate. The linkage drive screw 17 drives the two sets of drive blocks 18 to slide relative to each other, changing the hinge angle between the first connecting rod 19 and the second connecting rod 20, which in turn drives the first slide plate 14 to drive the support guide roller 16 to rise and support the aluminum profile. At the same time, the second slide plate 15 drives the lower clamping plate 11 to descend and loosen the profile, automatically completing the seamless switch from the profile clamping and traction state to the support and conveying state. After the equipment completes a single profile extrusion and cutting process and replaces the aluminum rod, the drive clamping and pulling mechanism moves in the reverse direction to reset to the initial clamping position (at the first end of the support roller group): During the initial movement, the linkage gear 22 rotates in the opposite direction relative to the linkage rack 23, driving the linkage drive screw 17 to rotate in the opposite direction, thereby controlling the first slide plate 14 to drive the support guide roller 16 to descend and avoid it, and the second slide plate 15 to drive the lower clamping plate 11 to rise and reset. During this process, the upper clamping plate 12 is not driven to move downward; and when returning to the first end of the support roller group... The linkage gear 22 meshes with the linkage rack 23 of the first end support roller group, and is adjusted again to the state where the support guide roller 16 rises and the lower clamping plate 11 falls, to support and transport the aluminum profile extruded from the new aluminum rod; after the next aluminum rod is extruded to the preset length, the clamping and pulling mechanism moves a short distance, the lower clamping plate 11 rises, and drives the upper clamping plate 12 to cooperate with the lower clamping plate 11 to clamp the profile again, realizing the automatic removal and cleaning of residual material. The entire process is automated and the working conditions are switched without manual intervention, which is suitable for the needs of continuous extrusion production.

[0036] See Figure 6In this embodiment, the two ends of the drive block 18 and the linkage drive screw 17 are connected by two sets of threaded segments with opposite directions. The linkage components are respectively provided in two sets corresponding to the drive block 18. The support guide rollers 16 are symmetrically provided in two sets on both sides of the lower clamping plate 11. The first connecting rods 19 of the two sets of linkage components are respectively hinged to the two sets of first sliding plates 14. The second connecting rods 20 of the two sets of linkage components are both hinged to the second sliding plate 15, and simultaneously drive the two sets of support guide rollers 16 to rise and fall.

[0037] See Figure 3 In this embodiment, the clamping and pulling mechanism further includes a pulling screw 24, a pulling guide rod, a pulling motor 25, and a mounting bracket 26. The pulling screw 24 is horizontally rotatably mounted on the equipment frame. One end of the pulling screw 24 is fixedly connected to the output shaft of the pulling motor 25. The pulling guide rod is fixed parallel to the side of the pulling screw 24. The mounting bracket 26 is threadedly connected to the pulling screw 24 via a threaded seat, and the mounting bracket 26 is slidably sleeved on the pulling guide rod. The pulling motor 25 drives the pulling screw 24 to rotate forward and backward, relying on the pulling... The guide rod guides and limits the movement, driving the mounting frame 26 to move back and forth precisely along the aluminum profile conveying direction; the adjustment box 13 is fixedly installed in the middle of the mounting frame 26 and moves synchronously with the mounting frame 26; the motion transmission component 4 is fixedly connected to the mounting frame 26; a lifting cylinder 27 is fixedly installed on the top of the mounting frame 26, and the upper clamping plate 12 is fixedly connected to the telescopic end of the lifting cylinder 27. The upper clamping plate 12 is driven to rise and fall vertically by the lifting cylinder 27, which can adapt to the clamping and fixing of aluminum profiles of different thicknesses and specifications, making the equipment more adaptable.

[0038] See Figure 2 In this embodiment, several cooling fans 28 are evenly installed on the conveying roller line. The cooling fans 28 are oriented towards the conveying surface of the aluminum profile, which can uniformly cool the newly extruded high-temperature aluminum profile, accelerate the shaping of the profile, and prevent the high-temperature profile from deforming under stress. The conveying roller line includes a first conveying roller line and a second conveying roller line connected front and rear. Multiple sets of movable support modules are arranged at intervals in the connection gap between the first conveying roller line and the second conveying roller line, perfectly connecting the front and rear conveying structures. The end of the second conveying roller line is equipped with a cutting mechanism 29. The cutting mechanism 29 adopts the existing mature profile fixed-length cutting technology and is used to perform fixed-length sawing processing on the formed aluminum profile. Through the segmented conveying structure and the middle liftable support structure, the continuity of conveying is ensured, and the profile cutting and residual material cleaning operations are convenient.
