Description

Technical Field

[0001] This utility model relates to the field of aluminum profile production technology, and in particular to an aluminum alloy profile extrusion production device. Background Technology

[0002] Aluminum alloy profile extrusion production equipment plays a core role in the aluminum alloy profile manufacturing industry. It is primarily used to produce various shapes of aluminum alloy profiles from aluminum alloy bars through extrusion molding. These profiles are widely used in numerous fields such as construction, automotive, and aerospace, and their quality and production efficiency directly impact the development of these related industries. In actual production scenarios, from the mass production of large industrial profiles to the processing of small, customized profiles, this equipment is indispensable. Currently, the practical application of this equipment typically requires the following technologies: 1. Stable bar support and conveying technology ensures that aluminum alloy bars can be smoothly conveyed to the designated position to prepare for subsequent extrusion molding; 2. Precise extrusion power technology provides sufficient and controllable power to the extrusion pusher, enabling the aluminum alloy bar to pass smoothly through the forming die and ensuring the forming quality of the profile; 3. Reliable mold fixing and forming technology ensures the stability of the forming mold during the extrusion process, thereby producing aluminum alloy profiles with the required shape accuracy; 4. Effective equipment control technology enables coordinated control of all components, ensuring automation and stability of the entire production process.

[0003] Currently, various equipment and methods are used to produce aluminum alloy profiles through extrusion. A common method involves using a support platform to hold the aluminum alloy bars. During loading, the inclined placement of the support platform provides guidance, allowing the bars to roll to a designated position under their own weight, thus securing them. The bars are then extruded through a die by an extrusion device, completing the profile production.

[0004] However, the above method has a prominent problem: when feeding aluminum alloy bars, the existing equipment relies solely on the tilting of the support platform for guidance and positioning, lacking an auxiliary clamping and positioning mechanism. This makes the position of the aluminum alloy bars prone to swaying during the feeding process. When controlling the extension of the extrusion rod, in order to avoid individual operations where extrusion production is carried out before the bar position is stable, a long waiting time is often required to ensure that it is in a stable state. This undoubtedly increases the time cost of each production cycle and cannot fully utilize its working efficiency. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an aluminum alloy profile extrusion production device. It solves the problem that existing devices rely solely on the tilted placement of the support platform for guidance and positioning during aluminum alloy bar feeding, lacking an auxiliary clamping and positioning mechanism. This method makes the aluminum alloy bar prone to wobbling during the feeding process. When controlling the extension of the extrusion rod, to avoid situations where extrusion production is carried out before the bar's position is stable, a long waiting time is often required to ensure it reaches a stable state. This undoubtedly increases the time cost of each production cycle and fails to fully utilize its working efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: An aluminum alloy profile extrusion production apparatus includes a bar support platform. A positioning mounting seat is provided on the outer surface of the bar support platform. A cross-shaped slider is slidably connected inside the positioning mounting seat. Two triangular positioning blocks are rotatably connected inside the positioning mounting seat. Two arc-shaped connecting rods are rotatably connected inside the cross-shaped slider. The two arc-shaped connecting rods are respectively rotatably connected inside the two triangular positioning blocks. A push cylinder is fixedly connected to the outer surface of the positioning mounting seat. The cross-shaped slider is disposed on the outer surface of the push cylinder. A round rod shaft is fixedly connected inside each of the two triangular positioning blocks.

[0007] Preferably, both of the two round rod shafts are rotatably connected inside the positioning mounting base, and a forming device is provided on one side of the bar support platform.

[0008] Preferably, a forming mold is fixedly connected inside the forming device, and an extrusion device is provided on the outer surface of the bar support platform away from the forming device.

[0009] Preferably, the extrusion device is provided with an extrusion push rod inside, and the outer surface of the bar support platform is provided with an L-shaped support.

[0010] Preferably, the L-shaped support is rotatably connected to a bar conveying plate, and both the L-shaped support and the outer surface of the bar conveying plate are fixedly connected to a set of arc-shaped supports.

[0011] Preferably, both sets of the arc-shaped supports are rotatably connected to a lifting cylinder, and a bar material processing device is provided on the side of the outer surface of the L-shaped support near the extrusion device.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. Before the extrusion molding operation, after the material is conveyed to the surface of the bar support table, the push cylinder installed on the positioning mounting base is activated. The cylinder output shaft extends and pushes the cross-shaped slider to slide. Inside the cross-shaped slider, two triangular positioning blocks are pulled synchronously and rotated in a centered manner through an arc connecting rod. The two triangular positioning blocks rotate around a central axis through an internally installed round rod shaft. As the cross-shaped slider slides out, it pushes the two triangular positioning blocks to rotate and center against the surface of the aluminum alloy bar, thus ensuring the stability of its placement state. This allows for quick and controllable placement and positioning of the bar, making the entire production process more stable and reliable. Compared with the traditional method of simply relying on the tilting of the support table and waiting for the bar to stabilize naturally, this method greatly saves positioning time, allowing the extrusion molding operation to be carried out faster, effectively shortening the production cycle of a single product, and increasing the output per unit time.

[0013] 2. After the bar stock is conveyed to the surface of the bar stock conveyor plate, two lifting cylinders are activated. The output axes of the two lifting cylinders extend outward, thereby pushing the bar stock conveyor plate to flip and convey the bar stock from the bar stock conveyor plate to the surface of the bar stock support platform.

[0017] This application provides an aluminum alloy profile extrusion production device that effectively solves the problem of existing devices relying solely on the tilted placement of the support table for guidance and positioning during aluminum alloy bar feeding, lacking an auxiliary clamping and positioning mechanism. This method makes the position of the aluminum alloy bar prone to wobbling during the feeding process. When controlling the extension of the extrusion rod, to avoid individual operations where extrusion production is carried out before the bar position is stable, a long waiting time is often required to ensure it is in a stable state. This undoubtedly increases the time cost of each production cycle and cannot fully utilize its working efficiency. Before the extrusion molding operation, the push cylinder mounted on the positioning mounting base is activated after the material is conveyed to the surface of the bar support table. By pushing the cylinder output shaft to extend and push the cross-shaped slider to slide, the cross-shaped slider pulls two triangular positioning blocks to rotate synchronously and center through the arc connecting rod inside the cross-shaped slider. The two triangular positioning blocks rotate around the internally installed round rod shaft. As the cross-shaped slider slides out, it pushes the two triangular positioning blocks to rotate and center and fit against the surface of the aluminum alloy bar, thus ensuring the stability of its placement state. The bar placement and positioning are completed quickly and controllably, making the entire production process more stable and reliable. Compared with the traditional method of simply relying on the tilting of the support table and waiting for the bar to stabilize naturally, it greatly saves positioning time, allows the extrusion molding operation to be carried out faster, effectively shortens the production cycle of a single product, and increases the output per unit time. Example

[0018] like Figures 1-4As shown, the technical solution in this application embodiment effectively solves the problem that existing devices rely solely on the tilted placement of the support platform for guidance and positioning when feeding aluminum alloy bars, lacking an auxiliary clamping and positioning mechanism. This method makes the position of the aluminum alloy bar prone to shaking during the feeding process. When controlling the extension of the extrusion rod, to avoid individual operations where extrusion production is carried out before the bar position is stable, a long waiting time is often required to ensure it is in a stable state. This undoubtedly increases the time cost of each production cycle and fails to fully utilize its working efficiency. The overall idea is as follows: An aluminum alloy profile extrusion production device includes a bar support platform 11. A positioning mounting seat 12 is provided on the outer surface of the bar support platform 11. A cross-shaped slider 13 is slidably connected inside the positioning mounting seat 12. Two triangular positioning blocks 14 are rotatably connected inside the positioning mounting seat 12. Two arc-shaped connecting rods 15 are rotatably connected inside the cross-shaped slider 13. The two arc-shaped connecting rods 15 are respectively rotatably connected inside the two triangular positioning blocks 14. A push cylinder 16 is fixedly connected to the outer surface of the positioning mounting base 12. A cross-shaped slider 13 is set on the outer surface of the push cylinder 16. Before the extrusion molding operation, the push cylinder 16 installed on the surface of the positioning mounting base 12 is activated. The output shaft of the push cylinder 16 extends and pushes the cross-shaped slider 13 to slide. Inside the cross-shaped slider 13, two triangular positioning blocks 14 are pulled synchronously and rotated in a centered manner through the arc connecting rod 15. The two triangular positioning blocks 14 rotate around the axis of the internally installed round rod shaft 17. While the cross-shaped slider 13 slides out, it pushes the two triangular positioning blocks 14 to rotate and center against the surface of the aluminum alloy bar, thereby ensuring the stability of its placement. After positioning is completed, the output shaft of the push cylinder 16 is controlled to retract. At this time, the cross-shaped slider 13 and the two triangular positioning blocks 14 are pulled away from the surface of the aluminum alloy bar to prepare for subsequent extrusion molding. The push cylinder 16 is powered by an air pump and controlled by buttons and programmed instructions in the control box.

[0019] Both triangular positioning blocks 14 have round rod shafts 17 fixedly connected inside, and both round rod shafts 17 are rotatably connected inside the positioning mounting base 12. A forming device 18 is provided on one side of the bar support platform 11, and a forming mold 19 is fixedly connected inside the forming device 18. An extrusion device 21 is provided on the outer surface of the bar support platform 11 away from the forming device 18, and an extrusion push rod 22 is provided inside the extrusion device 21. An L-shaped support 23 is provided on the outer surface of the bar support platform 11, and a bar conveying plate 2 is rotatably connected inside the L-shaped support 23. 4. Both the L-shaped support 23 and the outer surface of the bar conveying plate 24 are fixedly connected to a set of arc-shaped supports 25. Both sets of arc-shaped supports 25 are rotatably connected to lifting cylinders 26. After the bar is conveyed to the surface of the bar conveying plate 24, the two lifting cylinders 26 are activated. The output shafts of the two lifting cylinders 26 extend outward, thereby pushing the bar conveying plate 24 to flip and convey the bar from the bar conveying plate 24 to the surface of the bar support platform 11. The arc-shaped supports 25 provide support for the lifting cylinders 26 to avoid the phenomenon of the output shafts sticking out.

[0020] A bar material processing device 27 is provided on the side of the L-shaped support 23 near the extrusion device 21. The round aluminum alloy raw material used for extrusion molding to produce aluminum profiles is processed by the front bar material processing device 27 and then conveyed to the surface of the bar material conveying plate 24 at one end by a conveying device. The conveying device includes conveying rollers, support seats, and motors, sprockets, and chains that drive its rotation (same as existing conveying equipment technology). After the aluminum alloy bar is conveyed to the surface of the bar material support table 11, after ensuring its stability, the hydraulic drive mechanism contained inside the extrusion device 21 is activated. The hydraulic drive mechanism pushes the extrusion push rod 22 outward through the hydraulic rod and slides it. The extrusion push rod 22 extrudes and inserts the aluminum alloy bar into the forming mold 19. The aluminum alloy bar is extruded and shaped by the shape inside the forming mold 19, thereby producing aluminum alloy profiles through extrusion. The aluminum alloy profiles produced by extrusion are transferred by the rear conveying device and cooled and cut in the rear processing equipment to obtain the shaped product.

[0021] To address the problems existing in the prior art, this utility model provides an aluminum alloy profile extrusion production device. Before the extrusion molding operation, after the material is conveyed to the surface of the bar support table 11, the push cylinder 16 installed on the surface of the positioning mounting base 12 is activated. The output shaft of the push cylinder 16 extends and pushes the cross-shaped slider 13 to slide. Inside the cross-shaped slider 13, the arc connecting rod 15 pulls two triangular positioning blocks 14 to rotate synchronously in a centered manner. The two triangular positioning blocks 14 rotate around the axis of the internally installed round rod rotating shaft 17. As the cross-shaped slider 13 slides out, it pushes the two triangular positioning blocks 14 to rotate and center against the surface of the aluminum alloy bar, thereby ensuring the stability of its placement state and completing the bar placement and positioning quickly and controllably. This makes the entire production process more stable and reliable. Compared with the traditional method of simply relying on the tilting of the support table and waiting for the bar to stabilize naturally, it greatly saves positioning time, allows the extrusion molding operation to be carried out faster, effectively shortens the production cycle of a single product, and increases the output per unit time.

[0022] Working principle: In the first step, the round aluminum alloy raw material used for extrusion molding to produce aluminum profiles is processed by the front-end bar processing device 27 and then conveyed to the surface of the bar conveying plate 24 at one end by a conveying device. The conveying device includes conveying rollers, support seats, and a motor, sprockets, and chain (same as existing conveying equipment technology) to drive its rotation. After the bar is conveyed to the surface of the bar conveying plate 24, two lifting cylinders 26 are activated. The output axes of the two lifting cylinders 26 extend outward, thereby pushing the bar conveying plate 24 to flip and convey the bar from the bar conveying plate 24 to the surface of the bar support table 11. The arc support 25 provides support for the lifting cylinders 26. To avoid the output shaft from jamming, after the aluminum alloy bar is conveyed to the surface of the bar support platform 11, and its state is ensured to be stable, the hydraulic drive mechanism inside the extrusion device 21 is activated. The hydraulic drive mechanism pushes the extrusion push rod 22 outward through the hydraulic rod, and the aluminum alloy bar is extruded into the forming mold 19 through the extrusion push rod 22. The aluminum alloy bar is extruded and shaped by the shape inside the forming mold 19, thereby producing an aluminum alloy profile through extrusion. The aluminum alloy profile produced by extrusion is transferred by the rear conveying device and cooled and cut in the rear processing equipment to obtain the shaped product.

[0023] The second step involves activating the push cylinder 16 mounted on the positioning mounting base 12 before the extrusion molding operation, after the material is conveyed to the surface of the bar support platform 11. The output shaft of the push cylinder 16 extends to push the cross-shaped slider 13 to slide. Inside the cross-shaped slider 13, the arc connecting rod 15 pulls two triangular positioning blocks 14 to rotate synchronously in the center. The two triangular positioning blocks 14 rotate around the internally mounted round rod shaft 17. As the cross-shaped slider 13 slides out, it pushes the two triangular positioning blocks 14 to rotate and center against the surface of the aluminum alloy bar, thus ensuring the stability of its placement. After positioning is completed, the output shaft of the push cylinder 16 is retracted. At this time, the cross-shaped slider 13 and the two triangular positioning blocks 14 are pulled away from the surface of the aluminum alloy bar, preparing for subsequent extrusion molding. The push cylinder 16 is powered by an air pump and controlled by buttons and programmed instructions in the control box.

[0024] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
