Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy door and window production technology, and in particular to an aluminum alloy door and window bending machine. Background Technology

[0002] In the production of aluminum alloy doors and windows, profile bending is a crucial processing step that determines the shape and dimensional accuracy of the product. Currently, the industry commonly uses fixed bending machines for processing. These machines typically require operators to manually position and adjust the profile angles. Because the bending process demands high precision, traditional processing methods often rely on the operator's experience and skill level to complete bending operations at different angles.

[0003] Manual hand-held operation poses serious safety hazards. The operator's limbs are prone to interference with the bending mechanism, and prolonged operation can easily lead to fatigue and errors. At the same time, manual positioning is difficult to guarantee the accurate positioning of the profile, which can easily cause angular deviations and dimensional errors in mass production, directly affecting the product qualification rate. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a bending machine for the production of aluminum alloy doors and windows.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A bending machine for producing aluminum alloy doors and windows includes a base and a bending machine body. The bending machine body is installed at the upper middle position of the base. A bending blade is installed on the inner side of the top of the bending machine body. A bending groove is opened on the top of the base to cooperate with the bending blade. A slot is opened on the left side of the bending machine body at the top of the base. A mounting bracket is fixedly connected to the bottom of the base at the slot. A rotating plate is provided on the top of the base at the slot. The right end of the rotating plate is rotatably connected to the base through a third rotating bracket. A drive mechanism to assist the rotation of the rotating plate is provided in the mounting bracket. Clamping mechanisms are provided on both sides of the top of the rotating plate.

[0007] As a further improvement of this utility model, the driving mechanism includes a first rotating frame fixedly connected to the bottom of the mounting bracket, a hydraulic cylinder rotatably connected to the first rotating frame, a second rotating frame rotatably connected to the telescopic end of the hydraulic cylinder, and the second rotating frame fixedly connected to the bottom of the rotating plate.

[0008] As a further improvement of this utility model, the clamping mechanism includes a fixed frame fixedly connected to the top of the rotating plate, a cylinder fixedly connected to the top of the fixed frame, and the telescopic end of the cylinder passing through the fixed frame and fixedly connected to the clamping plate.

[0009] As a further improvement of this utility model, the top of the fixing frame is provided with guide columns on both sides of the cylinder, and the bottom ends of the two guide columns penetrate the fixing frame and are fixedly connected to the top of the clamping plate.

[0010] As a further improvement of this utility model, the top of the base is provided with an electric push rod fixedly connected to the base on the right side of the bending machine body. The telescopic end of the electric push rod is fixedly connected to a top block for clamping the profile.

[0011] As a further improvement of this utility model, the bottom of the base is supported by four support columns.

[0012] The beneficial effects of this utility model are:

[0013] By incorporating an automatic clamping mechanism and a rotation adjustment mechanism, the problem of manual operation required in traditional bending processes is completely eliminated. The cylinder-driven clamping plate automatically clamps the profile, while the hydraulic cylinder, through a rotating frame mechanism, drives the rotating plate to achieve automatic angle adjustment. Combined with the automatic clamping function of the electric push rod, the entire bending process reduces manual intervention, significantly minimizing operational safety hazards while ensuring consistent processing accuracy, thus significantly improving production efficiency and operational safety.

[0014] This invention utilizes a cylinder-driven automatic clamping mechanism, a hydraulic cylinder-controlled rotation adjustment mechanism, and an electric push rod positioning system to work together, thereby reducing safety hazards while ensuring simultaneous improvement in processing accuracy and production efficiency.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Figures 1-3 A bending machine for producing aluminum alloy doors and windows includes a base 1 and a bending machine body 10. The bottom of the base 1 is supported by four support columns 2 to maintain working stability. The bending machine body 10 is installed in the middle of the base 1 to ensure balanced force distribution. A bending blade 11 is installed on the inner side of the top of the bending machine body 10 to apply bending force to the profile. A bending groove 14 is opened on the top of the base 1 to cooperate with the bending blade 11 and to limit the deformation position of the profile. An electric push rod 12 is fixedly connected to the base 1 on the right side of the bending machine body 10. The extension of the electric push rod 12... A top block 13 is fixedly connected to the constricted end to tighten the profile and prevent displacement during processing. The top of the base 1 is provided with a slot 3 on the left side of the bending machine body 10 to provide an installation position. The bottom of the base 1 is fixedly connected to the mounting bracket 4 at the slot 3. The top of the base 1 is provided with a rotating plate 5 at the slot 3 for placing the profile to be processed. The right end of the rotating plate 5 is rotatably connected to the base 1 through a third rotating bracket 18. The mounting bracket 4 is provided with a drive mechanism to assist the rotation of the rotating plate 5. The drive mechanism is used to lift the rotating plate 5 and cooperate with the third rotating bracket 18 to achieve different angle adjustments.

[0021] The driving mechanism includes a first rotating frame 15 fixedly connected to the bottom of the mounting bracket 4. A hydraulic cylinder 16 is rotatably connected to the first rotating frame 15, which provides power output. A second rotating frame 17 is rotatably connected to the telescopic end of the hydraulic cylinder 16. The second rotating frame 17 is fixedly connected to the bottom of the rotating plate 5. The first rotating frame 15 and the second rotating frame 17 are composed of a fixed support, a rotating shaft, a connecting arm, and a bearing. Clamping mechanisms are provided on both sides of the top of the rotating plate 5. The two clamping mechanisms are arranged opposite each other and are used to clamp the bent profile. The clamping mechanism includes a fixed frame 6 fixedly connected to the top of the rotating plate 5. A cylinder 7 is fixedly connected to the top of the fixed frame 6 to drive the clamping action. The telescopic end of the cylinder 7 passes through the fixed frame 6 and is fixedly connected to a clamping plate 8. The clamping plate 8 is made of rubber. Guide posts 9 are provided on both sides of the top of the fixed frame 6 at the cylinder 7. The bottom ends of the two guide posts 9 pass through the fixed frame 6 and are fixedly connected to the top of the clamping plate 8 to ensure that the clamping plate 8 moves vertically without deviation.

[0022] In use, the aluminum alloy profile to be processed is first placed on the rotating plate 5. Then, two cylinders 7 are activated to push two clamping plates 8 to clamp and fix the profile. Then, the electric push rod 12 is operated to extend the top block 13 to press against the right end of the profile to prevent processing displacement. Then, the hydraulic cylinder 16 is activated to push the second rotating frame 17, which drives the rotating plate 5 to rotate around the third rotating frame 18 to the required bending angle. Finally, the bending machine body 10 is controlled to drive the bending knife 11 to press down, so that the profile is accurately bent at the bending groove 14. The whole process only requires manual placement of the profile and starting of the equipment, which greatly reduces the degree of manual intervention and reduces safety hazards.
