In order to facilitate the adjustment of the aluminum alloy pipes to the required angle, people have invented some processing equipment, including industrial aluminum alloy profile bending devices.

[0003] Existing equipment often relies on simple fixed molds or guide structures, and cannot make adaptive adjustments based on the actual deformation of copper pipes during bending. This causes copper pipes to easily deviate and twist during the bending process, which not only further reduces the bending accuracy, but also may cause surface damage to the copper pipe, affecting its service life and performance. Summary of the invention

[0021] Step 4: When the copper tube is bent to the required angle, stop the rotation of the bending wheel;

Several embodiments of the present invention are given in the drawings, but the present invention can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the content disclosed in the present invention more thorough and comprehensive.

The terms "vertical", "horizontal", "left", "right" and similar expressions used in this article are for illustrative purposes only.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly connected by technicians in the technical field to which the present invention belongs. The terminology used in the specification of the present invention is for the purpose of describing specific embodiments and is not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0036] The embodiment of the present application provides an aluminum alloy pipe processing mold. The schematic diagram of the aluminum alloy pipe bending equipment is as follows: Figure 1-5 The aluminum alloy pipe bending equipment comprises a bending table 10, one end of the bending table 10 is connected to a position adjustment mechanism 20, and the upper surface of the bending table 10 is connected to a bending mechanism 30;

[0037] The bending mechanism 30 includes a bending wheel 31 rotatably connected to the upper surface of the bending platform 10, a U-shaped frame 32 connected to the wheel body of the bending wheel 31, and a first rotating wheel 33 rotatably connected to the inner surface of the frame of the U-shaped frame 32. A gap is provided between the first rotating wheel 33 and the bending wheel 31 for the air conditioning copper pipe to pass through.

[0038] The bending mechanism 30 further includes a driven guide assembly 34 connected to the first rotating wheel 33 .

[0039] It should be noted that, in this embodiment, the position adjustment mechanism 20 enables the copper tube to be positioned accurately, improves the accuracy of the bending position, and reduces the bending errors caused by position deviation. The bending mechanism 30 can effectively realize the bending of the copper tube through the cooperation of the bending wheel 31 and the first rotating wheel 33, and the driven guide assembly 34 further ensures the stability and accuracy of the bending process, so that the bending angle meets the requirements.

[0040] Optional, please refer to the attached Figure 2 The driven guide assembly 34 includes second rotating wheels 341 connected to each other. The second rotating wheel 341 close to the first rotating wheel 33 is connected to the first rotating wheel 33, and the second rotating wheel 341 away from the first rotating wheel 33 is slidably connected to the bending table 10.

[0041] In this embodiment, the second rotating wheels 341 in the driven guide assembly 34 are connected to each other. The second rotating wheel 341 close to the first rotating wheel 33 is connected to the first rotating wheel 33 and can move with the movement of the first rotating wheel 33; the second rotating wheel 341 away from the first rotating wheel 33 is slidably connected to the bending table 10. When the copper tube is bent, these second rotating wheels 341 will rotate and slide accordingly according to the bending condition of the copper tube to play a guiding role. The setting and connection method of multiple second rotating wheels 341 can guide the copper tube more comprehensively, so that the copper tube maintains the correct direction during the bending process, avoids distortion or inaccurate bending angles, and improves the bending quality.

[0042] Optional, please refer to the attached Figure 2 , adjacent second rotating wheels 341 are connected via a first connecting rod 342 , and the second rotating wheel 341 and the adjacent first rotating wheel 33 are connected via a second connecting rod 343 .

[0043] In this embodiment, adjacent second rotating wheels 341 are connected by first connecting rods 342, and the second rotating wheels 341 and adjacent first rotating wheels 33 are connected by second connecting rods 343. This connecting rod connection mode enables each rotating wheel to form a linked whole. When one rotating wheel moves, it will drive the other rotating wheels to move together through the connecting rod, so as to better adapt to the bending process of the copper tube. The connecting rod connection enhances the integrity and coordination of the driven guide assembly 34, enables each rotating wheel to work synchronously, improves the stability and accuracy of the guide, and further improves the accuracy and quality of the copper tube bending.

[0044] Optional, please refer to the attached Figure 2 and 3 A sliding column 344 is connected to the bottom end of the second rotating wheel 341 away from the first rotating wheel 33 .

[0045] In this embodiment, a sliding column 344 is connected to the bottom end of the second rotating wheel 341 away from the first rotating wheel 33, and the sliding column 344 slides in a guide structure such as a guide slot on the bending table 10. When the copper tube is bent, the second rotating wheel 341 moves along with the bending of the copper tube, and the sliding column 344 can only slide along a specific track under the restriction of the guide structure, thereby ensuring that the movement direction of the second rotating wheel 341 is correct.

[0046] Optional, please refer to the attached Figure 2 The top of the bending platform 10 is provided with a long guide hole 11 for the sliding column 344 to slide.

[0047] In this embodiment, the long guide hole 11 at the top of the bending table 10 provides a sliding channel for the sliding column 344. The sliding column 344 slides in the long guide hole 11, thereby limiting the movement trajectory of the second rotating wheel 341, so that it can only move along the direction of the long guide hole 11, and cooperate with the bending process of the copper tube. The long guide hole 11 ensures the accuracy of the movement trajectory of the sliding column 344 and the second rotating wheel 341, further improves the guiding accuracy of the driven guide assembly 34, and ensures the quality and stability of the copper tube bending.

[0048] Optional, please refer to the attached Figure 1 The position adjustment mechanism 20 includes a support frame 21 connected to one end of the bending table 10, a screw rod 22 rotatably connected to the inside of the support frame 21, and a translation block 23 connected to the outer surface of the screw rod 22 through a nut, and a moving seat 24 is connected to the upper surface of the translation block 23.

[0049] In this embodiment, in the position adjustment mechanism 20, the motor 26 drives the reducer 25, and the reducer 25 drives the screw rod 22 to rotate. The screw rod 22 is connected to the translation block 23 through a nut, and the rotation of the screw rod 22 causes the translation block 23 to move linearly along the screw rod 22, and the moving seat 24 on the translation block 23 also moves accordingly, thereby realizing the adjustment of the position of the air conditioner copper pipe placed on the moving seat 24.

[0050] Optional, please refer to the attached Figure 1 The translation block 23 is slidably connected to the inner surface of the support frame 21 , and guide rods 231 are penetrated at both ends of the translation block 23 , and the guide rods 231 are connected to the inside of the support frame 21 .

[0051] In this embodiment, when the screw rod 22 drives the translation block 23 to move, the guide rod 231 guides the translation block 23, restricting it to move linearly along the direction of the guide rod 231, thereby preventing the translation block 23 from shaking or deflecting during the movement. The provision of the guide rod 231 improves the stability and accuracy of the movement of the translation block 23, ensures the accuracy of the position adjustment of the moving seat 24 and the copper tube, and thus improves the reliability of the entire bending process.

[0052] Optional, please refer to the attached Figure 1 and 5 The movable seat 24 is provided with a plug hole 241 for inserting the air conditioner through hole, and a receiving tube 242 is inserted into the hole body of the plug hole 241.

[0053] In this embodiment, the jack 241 on the movable seat 24 is used to insert the air conditioner copper tube, and the receiving tube 242 is inserted into the jack 241 to provide a stable placement space for the copper tube. Copper tubes of different specifications can use receiving tubes 242 with different inner diameters to adapt to copper tubes of different sizes.

[0054] Optional, please refer to the attached Figure 4 One end of the screw rod 22 extending into the interior of the bending platform 10 is connected to a reducer 25 , and an input end of the reducer 25 is connected to a motor 26 . Both the reducer 25 and the motor 26 are connected to the interior of the bending platform 10 .

[0055] In this embodiment, the power of the motor 26 is transmitted to the screw 22 through the reducer 25. The reducer 25 can reduce the rotation speed of the motor 26 and increase the torque, so that the screw 22 can rotate more stably and accurately, thereby achieving precise control of the position of the translation block 23 and the moving seat 24.

[0056] Based on the same inventive concept, this embodiment also provides a method for processing copper pipes during air conditioning manufacturing, comprising the following steps:

[0057] Step 1: insert one end of the air conditioner copper tube into the accommodating tube 242, so that the bent portion of the copper tube is roughly aligned with the gap between the bending wheel 31 and the first rotating wheel 33;

[0058] Step 2: Start the motor 26, drive the screw rod 22 to rotate through the reducer 25, so that the translation block 23 moves along the screw rod 22, thereby driving the moving seat 24 and the copper tube to move together; observe the position of the copper tube, and accurately adjust the position of the copper tube according to the bending requirements until a suitable bending position is reached;

[0059] Step three, the bending wheel 31 starts to rotate; as the bending wheel 31 rotates, the copper tube is gradually bent in the gap between the bending wheel 31 and the first rotating wheel 33; during the bending process, the second rotating wheel 341 of the driven guide assembly 34 rotates and slides as the copper tube bends, and through the connection of the first connecting rod 342 and the second connecting rod 343, each rotating wheel works together to provide auxiliary guidance for the copper tube, ensuring that the copper tube is bent according to a predetermined angle and shape

[0060] Step 4: When the copper tube is bent to a desired angle, the rotation of the bending wheel 31 is stopped;

[0061] The bent copper tube is taken out from the accommodating tube 242 and checked to see whether the bending angle meets the requirements.

[0062] The above is an exemplary description of the present invention in combination with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
