Description

Technical Field

[0001] This utility model relates to the field of bending equipment technology, specifically to an automatic bending device for aluminum profiles. Background Technology

[0002] An automatic aluminum profile bending device is a mechanical device used to bend aluminum alloy profiles. Through precise control, it can bend aluminum profiles to preset angles and shapes to meet the design requirements of different products. However, existing bending devices generally can only bend one end of the aluminum profile. When both ends need to be bent, one end must be bent, then the profile must be reloaded and bent again to bend the other end. This bending process is cumbersome, inefficient, and makes it difficult to ensure that the bending lengths at both ends are the same, leading to a decrease in product qualification rate. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an automatic bending device for aluminum profiles, which solves the technical problems of not being able to bend both ends of the aluminum profile simultaneously and the difficulty in ensuring that the bending lengths at both ends are the same.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an automatic bending device for aluminum profiles, including a machine body, a machine platform fixed on the machine body, a double-head bending mechanism for simultaneously bending both ends of the aluminum profile installed on the inner side of the machine platform, and two sets of limiting mechanisms for keeping the bending length of both ends of the aluminum profile consistent, and the two sets of limiting mechanisms are symmetrically arranged.

[0005] The dual-head bending mechanism includes a synchronous drive assembly installed inside the machine tool. Both ends of the synchronous drive assembly are connected to turntables. A bending column is fixedly installed on the surface of the turntable near the edge. A connecting plate fixedly connected to the synchronous drive assembly is provided on one side of the turntable. A guide column above the turntable is fixedly installed on the connecting plate. An adjustment assembly installed at the bottom of the machine tool is fixedly installed below the synchronous drive assembly.

[0006] Preferably, the synchronous drive assembly includes a motor one installed inside the machine tool. A worm gear is fixed on the output shaft of the motor one, and a worm wheel is provided above the worm gear and meshes with it. The worm wheel is fixed in the middle of the spline shaft. The spline shaft is rotatably connected to the machine tool through a bearing bracket. Both ends of the spline shaft have spline grooves and are fitted with spline sleeves. A bevel gear one is fixed on the outer wall of the spline sleeve. The bevel gear one meshes with a bevel gear two. The bevel gear two is fixed to the turntable through a rotating shaft. The rotating shaft and the spline sleeve are both rotatably connected to the fixed frame.

[0007] Preferably, the adjustment assembly includes a second motor installed at the bottom of the machine base. The output shaft of the second motor is fixedly connected to one end of a bidirectional lead screw. The bidirectional lead screw is rotatably connected to the bottom of the machine base. Both ends of the bidirectional lead screw are helically connected to sliders. The sliders are fixedly connected to the fixed frame and slidably disposed at the bottom of the machine base.

[0008] Preferably, the machine base has two through holes for the turntable to move left and right, and the two through holes are arranged symmetrically.

[0009] Preferably, the limiting mechanism includes a mounting base fixed to the machine base, an electric push rod fixed on the mounting base, and a limiting frame fixed on the telescopic shaft of the electric push rod.

[0010] Preferably, the inner side of the limiting frame is provided with a guide groove.

[0011] By employing the above technical solution, this utility model provides an automatic bending device for aluminum profiles, which has at least the following beneficial effects:

[0012] 1. This automatic aluminum profile bending device, by setting up a double-head bending mechanism, places the aluminum profile on the machine platform, and uses a synchronous drive component to drive two sets of turntables to rotate the bending column, thereby simultaneously bending both ends of the aluminum profile, which can improve the overall work efficiency. Moreover, under the action of the adjustment component, the distance between the two turntables can be adjusted according to the required bending length, which has the advantages of being adjustable and controllable.

[0013] 2. This automatic aluminum profile bending device, by setting a limiting mechanism, aligns the two ends of the aluminum profile with the limiting frame, and uses the guide groove on the limiting frame to place the aluminum profile on the machine table, thereby ensuring that the bending length of the two ends of the aluminum profile is the same, improving the consistency and pass rate of the product.

[0021] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Aluminum profiles are widely used in window frames, door frames, curtain walls, mechanical structural components, and many other industries. Their lightweight nature makes them a promising candidate for applications in automotive manufacturing, aerospace, electronics, and other fields. Traditional aluminum profile bending processes rely on manual operation or simple mechanical equipment, which is not only inefficient and time-consuming but also limits processing precision, easily generating scrap and increasing production costs. Furthermore, manual operation is inherently unstable during bending, potentially leading to inconsistent product quality. With technological advancements, especially in artificial intelligence, robotics, and precision control technology, automated production has become a major trend in manufacturing.

[0023] Example 1:

[0024] Due to the limitations of existing technology, such as the inability to simultaneously bend both ends of aluminum profiles and the difficulty in ensuring that the bending lengths at both ends are the same, please refer to... Figures 1-4This utility model provides an automatic aluminum profile bending device that can simultaneously bend both ends of an aluminum profile, improving overall work efficiency and ensuring that the bending lengths at both ends of the aluminum profile are the same, thus improving product consistency and pass rate. The device includes a machine body 1, on which a machine platform 2 is fixed. A double-headed bending mechanism 3 for simultaneously bending both ends of the aluminum profile is installed on the inner side of the machine platform 2. Two sets of limiting mechanisms 4 are also fixed on the machine platform 2 to keep the bending lengths at both ends of the aluminum profile consistent, and the two sets of limiting mechanisms 4 are symmetrically arranged. Under the action of the limiting mechanisms 4, the aluminum profile is accurately placed on the machine platform 2, and then under the action of the double-headed bending mechanism 3, both ends of the aluminum profile are bent simultaneously. After bending, the aluminum profile can be removed.

[0025] To improve the bending efficiency of aluminum profiles, please refer to... Figure 3 The double-head bending mechanism 3 includes a synchronous drive assembly 301 installed inside the machine base 2. Both ends of the synchronous drive assembly 301 are connected to turntables 302. Bending columns 303 are fixedly installed on the surface of the turntables 302 near the edge. A connecting plate 304 fixedly connected to the synchronous drive assembly 301 is provided on one side of the turntables 302. A guide column 305 above the turntables 302 is fixedly installed on the connecting plate 304. An adjustment assembly 306 installed at the bottom of the machine base 2 is fixedly installed below the synchronous drive assembly 301. The synchronous drive assembly 301 drives the two turntables 302 to rotate the bending columns 303, thereby synchronously bending both ends of the aluminum profile. Under the action of the adjustment assembly 306, the distance between the two turntables 302 can be adjusted according to the required bending length.

[0026] To achieve simultaneous bending at both ends of the aluminum profile, please refer to... Figure 3 The synchronous drive assembly 301 includes a motor 3011 mounted inside the machine base 2. A worm gear 3012 is fixed on the output shaft of the motor 3011. A worm wheel 3013 is located above the worm gear 3012 and meshes with it. The worm wheel 3013 is fixed in the middle of a splined shaft 3014. The splined shaft 3014 is rotatably connected to the machine base 2 via a bearing bracket 3015. Both ends of the splined shaft 3014 have spline grooves and are fitted with spline sleeves 3016. A bevel gear 3017 is fixed on the outer wall of the spline sleeve 3016. The bevel gear 3017 and the bevel gear 3018 are connected. The bevel gear 3018 is meshed with the turntable 302 via the shaft 3019. The shaft 3019 and the spline sleeve 3016 are both rotatably connected to the fixed frame 30110. The motor 3011 drives the spline shaft 3014 to rotate through the meshing action of the worm gear 3012 and the worm wheel 3013. The spline shaft 3014 drives the bevel gear 3017 to rotate through the spline sleeve 3016. The bevel gear 3017 drives the turntable 302 to rotate through the meshing action of the bevel gear 3018, thereby causing the bending column 303 to move and bend the aluminum profile.

[0027] To adjust the bending length at both ends of the aluminum profile according to actual needs, please refer to... Figure 3 The adjustment assembly 306 includes a second motor 3061 installed at the bottom of the machine base 2. The output shaft of the second motor 3061 is fixedly connected to one end of a double-acting lead screw 3062. The double-acting lead screw 3062 is rotatably connected to the bottom of the machine base 2. Slider blocks 3063 are screwed to both ends of the double-acting lead screw 3062. The sliders 3063 are fixedly connected to the fixed frame 30110 and slidably disposed at the bottom of the machine base 2. The second motor 3061 works and drives the two fixed frames 30110 to move horizontally through the screw drive of the double-acting lead screw 3062 and the sliders 3063. Since the spline sleeve 3016 can move on the spline shaft 3014 without affecting the transmission, the distance between the two turntables 302 can be adjusted.

[0028] To avoid restricting the movement of the turntable 302, two through holes are provided on the machine base 2 for the turntable 302 to move left and right, and the two through holes are arranged symmetrically; under the action of the through holes, the turntable 302 can move without restriction.

[0029] Example 2:

[0030] When bending the two ends of the aluminum profile, it is necessary to ensure that the lengths of the two ends of the aluminum profile and the bending post 303 are the same. Therefore, after placing the aluminum profile, it is also necessary to measure the bending lengths of the two ends of the aluminum profile using a measuring tool. This method is inconvenient and affects work efficiency. To solve this problem, please refer to... Figure 4 The limiting mechanism 4 includes a mounting base 401 fixed to the machine base 2, an electric push rod 402 fixed on the mounting base 401, and a limiting frame 403 fixed on the telescopic shaft of the electric push rod 402. The two ends of the aluminum profile are aligned with the limiting frame 403, and the aluminum profile is placed on the machine base 2 by using the guide groove 4031 on the limiting frame 403. This ensures that the bending lengths of the two ends of the aluminum profile are the same, and the position of the limiting frame 403 can be adjusted under the action of the electric push rod 402 to accommodate aluminum profiles of different lengths.

[0031] To ensure that the aluminum profile can be better positioned, a guide groove 4031 is provided on the inner side of the limit frame 403.

[0032] As can be seen from the above embodiments: under the action of the limiting mechanism 4, the two ends of the aluminum profile are aligned with the limiting frame 403. The guide groove 4031 on the limiting frame 403 is used to place the aluminum profile on the machine base 2, thereby ensuring that the bending lengths of the two ends of the aluminum profile are the same. Then, under the action of the double-head bending mechanism 3, the motor 3011 works and drives the spline shaft 3014 to rotate through the meshing action of the worm 3012 and the worm wheel 3013. The spline shaft 3014 drives the bevel gear 3017 to rotate through the spline sleeve 3016. The bevel gear 3017 drives the turntable 302 to rotate through the meshing action with the bevel gear 3018, thereby causing the bending column 303 to move and bend the aluminum profile. After bending, the aluminum profile is removed.
