Description

Technical Field

[0001] This utility model relates to the field of bending device technology, and in particular to a bending device for aluminum profile production and processing. Background Technology

[0002] Aluminum profiles, with their excellent properties such as light weight, high specific strength, corrosion resistance, and ease of processing, are widely used in many fields, including architectural decoration, rail transportation, aerospace, and electronics. In the production and processing of aluminum profiles, the bending process is a crucial step in achieving specific geometric shapes. Its processing quality directly determines the assembly accuracy, structural stability, and appearance consistency of the aluminum profile products. Therefore, optimizing the performance of aluminum profile bending equipment has always been one of the core directions of technological research and development in the industry.

[0003] Currently, there are various aluminum profile bending devices on the market. Their basic working mode is to fix the aluminum profile through a positioning mechanism, and then use the bending actuator to apply external force to make the profile bend and deform around the preset support point. For example, some traditional bending devices use a support member of fixed height to support the bottom of the aluminum profile, and use a manual or pneumatic clamping mechanism to position the profile. The bending arm is driven by a motor to rotate around a fixed axis to complete the bending action. Some improved devices attempt to adjust the support structure, but they mostly use a graded adjustment method of bolt tightening. Different specifications of profiles are adapted by replacing shims of different thicknesses or disassembling and adjusting the height of the support member.

[0004] However, most existing aluminum profile bending devices use a fixed-height support structure, and the support height cannot be adjusted. When processing aluminum profiles with different heights, thicknesses, and different stiffener spacings, the entire support assembly must be replaced. This not only increases the inventory cost of equipment parts but also requires a lot of time for equipment disassembly and debugging, leading to extended production interruption time and severely reducing production efficiency. Therefore, we propose a bending device for aluminum profile production and processing. Utility Model Content

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0028] Example 1:

[0029] Reference Figures 1-5 This is the first embodiment of the present invention. This embodiment provides a bending device for aluminum profile production and processing, including a workbench 1, a linear slide rail 2 installed on the upper surface of the workbench 1, a positioning component 3 installed on the moving end of the linear slide rail 2, a fixed support 4 fixedly installed on one end of the linear slide rail 2 on the upper surface of the workbench 1, a movable support 41 installed on the upper end of the fixed support 4, a lifting component 42 for driving the movable support 41 to adjust its position on the upper end of the movable support 41, and connecting grooves 43 for connecting profile reinforcing ribs are provided on the outer walls of both the movable support 41 and the fixed support 4, and a bending component 5 is provided on the upper surface of the workbench 1.

[0030] In use, the height of the movable support 41 is adjusted according to the height of the aluminum profile and the spacing between the two sets of reinforcing ribs. By moving the movable support 41, the spacing between the fixed support 4 and the two sets of connecting grooves 43 on the movable support 41 can be adjusted. This allows for adjustment according to different specifications of aluminum profiles, thus improving the applicability of the equipment.

[0031] Specifically, the lifting assembly 42 includes a guide groove 422 extending through the axis of the movable support 41. A guide shaft 421 is slidably installed inside the guide groove 422. The lower end of the guide shaft 421 is fixedly connected to the upper end of the fixed support 4. The upper end of the guide shaft 421 extends to the upper side of the movable support 41 and is fixedly connected to a lifting electric actuator 423 via a bracket. The output end of the lifting electric actuator 423 is fixedly connected to the movable support 41.

[0032] The U-shaped bracket adopts a welded structure, and its inner wall is fixed to the outer wall of the guide shaft 421 by welding. The top of the bracket is detachably connected to the cylinder flange of the lifting electric push rod 423 by bolts, which facilitates later maintenance and replacement.

[0033] During adjustment, the lifting electric actuator 423 of the lifting assembly 42 is activated. The output end of the lifting electric actuator 423 drives the movable support 41 to move up and down along the guide shaft 421 until the movable support 41 and the fixed support 4 form a support structure that adapts to the height of the profile. The plug 45 at the upper end of the fixed support 4 is inserted into the plug groove 44 at the lower end of the movable support 41 to enhance the stability of the connection between the two.

[0034] Subsequently, the reinforcing ribs of the aluminum profile are inserted into the connecting grooves 43 on the outer walls of the movable support 41 and the fixed support 4. The reinforcing ribs enhance the structural strength of the aluminum profile during the bending process and prevent local deformation.

[0035] This device flexibly adjusts the height of the movable support 41 via the lifting electric actuator 423, adapting to aluminum profiles of different heights and thicknesses. At the same time, by adjusting the height of the movable support 41, the distance between the two sets of connecting slots 43 can be adjusted, making it suitable for profiles of different specifications. It can not only meet the bending support requirements of different profiles, but also enhance the deformation resistance of the profiles during bending through reinforcing ribs, avoiding processing limitations or finished product defects caused by differences in profile specifications.

[0036] Specifically, the lower outer wall of the movable support 41 is provided with several insertion slots 44, and the upper end of the fixed support 4 is fixedly installed with several insertion pieces 45 that are adapted to the insertion slots 44. The insertion pieces 45 are respectively inserted into the corresponding insertion slots 44.

[0037] The connector 45 is made of wear-resistant alloy steel, and its ends are chamfered for easy insertion and assembly.

[0038] Example 2:

[0039] Reference Figures 1-2 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0040] Specifically, the positioning component 3 includes a fixed frame 31 fixedly installed on the moving end of the linear slide rail 2. A clamping member 34 is fixedly installed on one end of the upper surface of the fixed frame 31, and a positioning electric push rod 32 is fixedly installed on the other end of the upper surface of the fixed frame 31. A clamping member 33 is fixedly installed on the output end of the positioning electric push rod 32.

[0041] The fixed frame 31 is made of high-strength aluminum alloy profiles and is rigidly connected to the moving end of the linear slide rail 2 by bolts at the bottom. The connection surface is equipped with shock-absorbing pads to reduce vibration transmission. The linear slide rail 2 is a heavy-duty ball bearing linear slide rail with a rated dynamic load of not less than 50kN, ensuring smooth translation even when the profile is clamped.

[0042] In use, the aluminum profile to be bent is placed on the fixed frame 31 of the positioning component 3, and the positioning electric push rod 32 is activated. Its output end pushes the clamping part 1 33 to move towards the clamping part 2 34. Through the relative clamping force between the clamping part 1 33 and the clamping part 2 34, the aluminum profile is horizontally fixed in the horizontal direction. At the same time, the moving end of the linear slide rail 2 can drive the fixed frame 31 to move horizontally along the length direction of the worktable 1, accurately adjust the distance between the aluminum profile and the fixed support 4, determine the bending start position, and complete the bidirectional precise positioning of the profile.

[0043] Example 3:

[0044] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0045] Specifically, the bending assembly 5 includes a groove 51 formed on the upper surface of the workbench 1, and an L-shaped bracket 55 is slidably installed inside the groove 51.

[0046] The slide 51 is arc-shaped, and its center is on the same axis as the center of the fixed support 4.

[0047] Specifically, one end of the L-shaped bracket 55 is located on the upper side of the workbench 1 and is fixedly connected to a mounting base 52 by welding. The mounting base 52 is a rectangular steel plate structure, and its end is fixedly connected to the movable electric actuator 53 by a triangular bracket. The triangular bracket adopts a welded reinforcement design and can withstand the axial thrust generated by the movable electric actuator 53 during operation. The movable electric actuator 53 is a high-thrust model with a rated thrust of not less than 10kN, and its output end is fixedly connected to the bending drive component 54 by bolts. The working end of the bending drive component 54 adopts a detachable structure, and bending dies of different curvatures can be replaced according to different bending requirements.

[0048] Specifically, the other end of the L-shaped bracket 55 extends vertically downward into the interior of the worktable 1. A rotating shaft 56 is fixedly installed at this end via a key connection. The key connection adopts a flat key connection structure to ensure the reliability of torque transmission. The upper end of the rotating shaft 56 is rotatably installed in a pre-set bearing seat on the inner wall of the worktable 1 via a deep groove ball bearing. The bearing seat is made of cast steel and is fixed to the inner wall of the worktable 1 with bolts. The bearing is filled with lithium-based grease, which can achieve long-term maintenance-free operation. A sealing ring is provided between the bearing seat and the rotating shaft 56 to prevent dust and impurities inside the worktable 1 from entering the bearing and affecting the rotation accuracy.

[0049] Specifically, the center of the rotating shaft 56 and the sliding groove 51 are set on the same axis as the center of the fixed support 4.

[0050] This ensures that the aluminum profile always bends and deforms with the fixed support 4 as the reference center during the bending process, avoiding bending angle deviations caused by center offset. To achieve this high-precision coaxiality, the device uses specialized positioning fixtures to calibrate all three components during assembly, ensuring that the assembly accuracy meets design requirements.

[0051] Specifically, a gearbox 57 and a drive motor 58 are mounted inside the workbench 1 via a bracket. The output end of the gearbox 57 is fixedly connected to the lower end of the rotating shaft 56, and the output end of the drive motor 58 is fixedly connected to the input end of the gearbox 57.

[0052] Gearbox 57 uses a hardened cylindrical gear reducer with a reduction ratio set to 1:10 according to the bending speed requirement. This converts the high-speed rotation of drive motor 58 into low-speed, high-torque rotation of shaft 56. The output end of gearbox 57 is fixedly connected to the lower end of shaft 56 via a flange. Drive motor 58 is a servo motor with a rated power of not less than 1.5kW, possessing precise speed control capabilities. The bending angle can be accurately adjusted via a servo controller. The output end of drive motor 58 is fixedly connected to the input end of gearbox 57 via a flexible coupling. The flexible coupling can compensate for minor coaxiality errors between the motor shaft and the input shaft of gearbox 57, reducing vibration transmission and protecting the service life of the motor and gearbox 57.

[0053] During bending, the moving electric push rod 53 of the bending assembly 5 is activated, and its output end pushes the bending drive 54 toward the part of the aluminum profile to be bent, until the bending drive 54 is in close contact with the surface of the profile, and the contact force can be precisely controlled by the moving electric push rod 53 to avoid excessive compression that could damage the surface of the profile.

[0054] Next, the drive motor 58 is started. The power of the drive motor 58 is reduced in speed and increased in torque by the gearbox 57, and then the power is transmitted to the rotating shaft 56. The rotating shaft 56 drives the L-shaped bracket 55, which is fixedly connected to it, to rotate around the axis of the rotating shaft 56. Since the other end of the L-shaped bracket 55 is slidably installed in the arc-shaped groove 51, and the center of the rotating shaft 56, the groove 51 and the center of the fixed support 4 are collinear, the L-shaped bracket 55 will slide smoothly along the arc-shaped trajectory of the groove 51, thereby driving the bending drive 54 to apply a continuous and uniform bending force to the aluminum profile, so that the aluminum profile gradually bends around the axis of the fixed support 4 until the preset bending angle is reached.

[0055] After bending is completed, the drive motor 58 rotates in the opposite direction, driving the L-shaped bracket 55 and bending drive component 54 to reset. The positioning electric push rod 32, moving electric push rod 53, and lifting electric push rod 423 are reset in sequence, releasing the clamping and support of the aluminum profile. Finally, the bent aluminum profile is taken out, completing one bending process.

[0056] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
