Description

Technical Field

[0001] This utility model relates to the field of aluminum profile processing technology, and specifically to a bending and diameter-changing structure for aluminum profile processing. Background Technology

[0002] Aluminum profiles, with their excellent lightweight, corrosion resistance, and ease of processing, have become a key basic material in many fields such as building curtain walls, automotive frames, and aerospace structural components. With the expansion of application areas and the increasing complexity of product designs, the demand for high-precision, high-efficiency bending processing of aluminum profiles is becoming increasingly urgent.

[0003] In traditional aluminum profile bending processes, a one-time bending forming method based on tooling with a fixed curvature or radius is mainly adopted. One typical approach is to design a dedicated mold and use a press to apply pressure to the aluminum profile to bend it to the target shape in one go. Although this method is relatively simple to operate and has a low initial investment cost, making it particularly suitable for the production of mass-produced, standardized products, its bending accuracy and shape fidelity are severely limited by the design accuracy and wear condition of the mold. More importantly, due to the inherent material properties of aluminum profiles, applying a large deformation force in a single operation can easily lead to significant elastic rebound and distortion or collapse of the profile cross-section (such as hollow cavities), directly affecting the dimensional accuracy, structural strength, and appearance quality of the product. Another common method is to use a hydraulic pipe bending machine or a CNC bending machine to achieve bending processing through angle control of the equipment. This method has a certain degree of flexibility in bending angle, but to achieve different bending radii or complex curvatures, it is still necessary to customize a dedicated bending mold or tooling for each specific curvature requirement. This results in poor equipment adaptability and versatility, high tooling costs, and poor economic efficiency, especially in small-batch, multi-variety production.

[0004] To overcome the problems of low yield and unstable precision caused by traditional one-time bending processes, existing technologies have gradually developed a step-by-step bending strategy. This strategy decomposes the target bending deformation into multiple stages of small deformation, aiming to disperse the stress of a single forming by multi-stage deformation, thereby effectively reducing the risk of material springback and cross-sectional deformation, and significantly improving the processing yield. However, the step-by-step bending process itself introduces new efficiency bottlenecks. The main problem is that each bending stage often requires independent and dedicated tooling for targeted adjustments. When continuously processing different bending stages, tooling must be switched frequently, which is cumbersome and time-consuming. Moreover, each tooling switch is often accompanied by the re-clamping of the aluminum profile workpiece. This repeated loading and unloading operation significantly increases non-processing time and seriously restricts overall production efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a bending and diameter-changing structure for aluminum profile processing. By setting a second bending platform that can rotate, it solves the problem that when processing different bending stages continuously, it is necessary to frequently switch tooling, which is cumbersome and time-consuming. Moreover, each tooling switch is often accompanied by the re-clamping of the aluminum profile workpiece. This repeated loading and unloading operation significantly increases non-processing time and seriously restricts the overall production efficiency.

Aluminum profile. Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0034] like Figures 1-6 As shown, this utility model provides a bending and diameter-changing structure for aluminum profile processing. By setting a rotatable second bending platform 9, the bending radius can be flexibly adjusted during continuous processing of different bending stages without re-clamping the aluminum profile workpiece. Continuous bending processing of multiple target radii can be achieved using a single tooling system.

[0035] like Figures 1-5 As shown, the above-mentioned bending and reducing structure for aluminum profile processing includes a base 1. The base 1 allows the entire bending and reducing structure to be installed on different operating platforms for flexible turnover processing.

[0036] A base plate 2 is fixedly installed on the top surface of the base 1 by bolts. Two sets of support columns 4 are arranged in a straight line along the length of the base 1 on one side of the top of the base plate 2. A first bending platform 5 is set on the top of the support columns 4. The first bending platform 5 is fixed on the two sets of support columns 4 and remains horizontal during the bending stage.

[0037] Furthermore, side plates 6 are symmetrically arranged at both ends of the first bending platform 5 near the middle of the base 1. Bearing seats 7 are provided on the outer top of each of the two side plates 6. Rotary bearings are installed inside the two bearing seats 7, and the two sets of rotary bearings are fitted with a limit shaft 8. A second bending platform 9 is rotatably connected to the limit shaft 8. A mounting base 10 is provided on the top of the side of the base 1 away from the first bending platform. A hydraulic cylinder 11 is rotatably arranged in the mounting base 10. The telescopic rod of the hydraulic cylinder 11 is movably connected to the second bending platform 9. The second bending platform 9 is driven to rotate around the limit shaft 8 by the hydraulic cylinder 11 to adjust the bending radius.

[0038] Furthermore, both the first bending platform 5 and the second bending platform 9 are provided with outer shell plates 3 to protect the internal parts.

[0039] Furthermore, specifically as follows Figure 3 and Figure 5 As shown, the top of the first bending platform 5 and the second bending platform 9 are both bolted with support seats 13. Support shafts are rotatably mounted on both support seats 13, and the distance between the axis of the two sets of support shafts and the axis of the limiting shaft 8 is consistent, so as to keep the curvature of the left and right sides of the aluminum profile 100 consistent and avoid uneven bending force that could damage the aluminum profile 100.

[0040] Furthermore, such as Figure 1 and Figure 2 As shown, the first bending platform 5 and the second bending platform 9 are provided with multiple sets of horizontally distributed mounting holes. When bending different aluminum profiles 100, the initial bending radius in the step-by-step bending process can be changed by changing the position of the support seat 13 set on the first bending platform 5 and the second bending platform 9, thereby optimizing the step-by-step bending process and improving bending efficiency.

[0041] Furthermore, multiple sets of vertically distributed mounting holes are provided on the side plates 6 on both sides. When bending different aluminum profiles 100, the position of the limiting shaft 8 can be adjusted, and the aluminum profile 100 can be bent by the limiting shaft 8 in conjunction with the support shafts on both sides.

[0042] Furthermore, such as Figure 6 As shown, the inner side of the aforementioned side plate 6 is provided with a limiting platform 61, which is crescent-shaped, and limiting portions 62 are provided at both ends of the limiting platform 61; the second bending platform 9 includes a platform body 91, and two sets of upwardly inclined rotating arms 92 are provided on the side of the platform body 91 near the side plate 6. The two sets of rotating arms 92 are rotatably mounted at both ends of the limiting shaft 8, and the two sets of rotating arms 92 cooperate with the limiting platform 61. The rotation angle of the rotating arms 92 is limited by the limiting portions 62 on both sides, thereby controlling the rotation angle of the second bending platform 9 and avoiding excessive rotation that could damage the parts.

[0043] Furthermore, a guide rod 93 is rotatably installed on the side of the platform body 91 near the limiting shaft 8 to facilitate the unloading of the aluminum profile 100 after bending, and to avoid scratching the surface of the aluminum profile 100. A connecting seat 12 is provided on the side of the platform body 91 near the hydraulic cylinder 11, and the telescopic rod of the hydraulic cylinder 11 is rotatably connected to the connecting seat 12.

[0044] It should be noted that a driving component is provided on one side of the limiting shaft 8 in this utility model. This driving component can be as follows: Figure 2 The drive handle 14 shown can be driven manually or by a drive motor (not shown in the figure), which drives the limit shaft 8 to rotate.

[0045] Working principle of this utility model:

[0046] According to the bending requirements of the aluminum profile 100, adjust the positions of the two sets of support seats 13 and limit shaft 8, start the hydraulic cylinder 11, drive the second bending platform 9 to rotate downward, and guide the unbent aluminum profile 100 from one side of the first bending platform 5. Then, start the hydraulic cylinder 11 to drive the second bending platform 9 to reset upward and move to a position parallel to the first bending platform 5 to achieve initial bending. When the initial bending is completed, start the hydraulic cylinder 11 to drive the second bending platform 9 to continue to deflect upward, adjust the bending radius, and further bend the aluminum profile 100. Repeat this process until the set bending radius is reached.

[0047] After bending is complete, the start cylinder 11 drives the second bending platform 9 to deflect downwards, releasing the aluminum profile 100. The drive handle 14 is rotated to drive the limit shaft 8 to rotate, accelerating the separation of the bent aluminum profile 100.

[0048] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
