[0038] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0039] Example 1:

[0040] Combination Figure 1 , Figure 2 As shown, the automatic tube bending and punching machine of this embodiment includes a worktable 1, on which a feeding mechanism 2, a tube bending mechanism 3, a punching mechanism 4, and a receiving mechanism 5 are provided. The feeding mechanism 2 is used to move flat aluminum tubes one by one to the tube bending mechanism 3. The tube bending mechanism 3 is used to bend the flat aluminum tubes. The punching mechanism 4 is used to punch holes on both sides of the bent flat aluminum tubes. The receiving mechanism 5 is used to transfer the punched flat aluminum tubes to the receiving point. The tube bending mechanism 3 includes a first bending edge alignment component 6, a tube bending machine 7, and a second bending edge alignment component 8. The first bending edge alignment component 6 is used to perform the first bending edge alignment positioning of the flat aluminum tubes. The tube bending machine 7 is used to bend the flat aluminum tubes. The second bending edge alignment component 8 is used to perform the second bending edge alignment positioning of the flat aluminum tubes.

[0041] The feeding mechanism 2 can move flat aluminum tubes one by one from the hopper and deliver them smoothly and accurately to the processing position of the bending mechanism 3. The bending mechanism 3 includes a first bending and aligning assembly 6, a bending machine 7, and a second bending and aligning assembly 8. The first bending and aligning assembly 6 performs initial positioning and aligning adjustment on the incoming flat aluminum tubes; the bending machine 7 can perform precise and stable bending processing on the flat aluminum tubes according to preset parameters; the second bending and aligning assembly 8 further ensures the accuracy of the shape and size of the bent flat aluminum tubes, eliminating possible errors during the bending process through re-aligning and fine-tuning. The punching mechanism 4 punches holes on both sides of the bent flat aluminum tubes simultaneously or separately, with accurate hole positions and consistent hole diameters. The receiving mechanism 5 is responsible for safely and orderly transferring the punched flat aluminum tubes to the designated receiving point, such as... Figure 11, 12 The diagram shown is a schematic of the product structure before and after bending.

[0042] Specifically, such as Figure 3 , Figure 8 As shown, the first bending edge assembly 6 includes a first cylinder 61 set on the workbench 1. The output end of the first cylinder 61 is connected to a first positioning push plate 62. A first servo motor 63 is installed on the first positioning push plate 62. The output end of the first servo motor 63 is connected to a first gripper 64.

[0043] Specifically, the first bending edge alignment assembly 6 is used to precisely position and initially adjust the edges of the flat aluminum tube entering the bending process. The first bending edge alignment assembly 6 is located in a specific area of ​​the workbench 1 and includes a first cylinder 61 on the workbench 1, ensuring its stability and reliability during operation. The output end of the first cylinder 61 is tightly connected to a first positioning push plate 62 via a high-strength connector.

[0044] The first positioning push plate 62 is used for initial positioning of the flat aluminum tube. A first servo motor 63 is installed above or on the side of the first positioning push plate 62. The first servo motor 63 can control the rotation angle and speed, providing power support for the subsequent movement of the first gripper 64. The output end of the first servo motor 63 is connected to the first gripper 64 through a coupling to realize the clamping and releasing of the flat aluminum tube.

[0045] like Figure 4 , Figure 10 As shown, during the first bending and edge alignment process, the first gripper 64, driven by the servo motor, clamps the flat aluminum tube and, in conjunction with the pushing action of the first positioning push plate 62, completes the initial positioning and edge alignment adjustment of the flat aluminum tube. The second bending and edge alignment assembly 8 includes a second cylinder 81 set on the worktable 1. The output end of the second cylinder 81 is connected to a positioning rod 82. The top end of the positioning rod 82 is provided with a positioning block 83 for inserting into the flat aluminum tube. A mounting bracket 84 is set on the positioning rod 82. A third cylinder 85 is set on the mounting bracket 84. The output end of the third cylinder 85 is connected to a second positioning push plate 86. The bottom of the second positioning push plate 86 is provided with a V-shaped opening 87. The rod body of the positioning rod 82 is inserted into the V-shaped opening 87.

[0046] Specifically, the second bending and edge processing assembly 8 realizes the secondary positioning and stable clamping of the flat aluminum pipe. The second bending and edge processing assembly 8 is stably installed in a specific area of the workbench 1 to support its mechanical structure. The output end of the second air cylinder 81 is connected with the positioning rod 82, which not only bears the force of the air cylinder, but also precisely positions the flat aluminum pipe. Meanwhile, a positioning block 83 matching the internal structure of the flat aluminum pipe is arranged at the top end of the positioning rod 82. The positioning block 83 ensures smooth and stable insertion into the interior of the flat aluminum pipe, providing an accurate reference for subsequent bending and edge processing operations. At the same time, it can effectively prevent the pipe from deforming during the bending process.

[0047] A mounting bracket 84 is arranged on the rod body of the positioning rod 82, which not only provides a stable installation basis for the subsequent third air cylinder 85 and second positioning push plate 86, but also realizes multi-point positioning and clamping of the flat aluminum pipe. The third air cylinder 85 is installed on the mounting bracket 84 and can control the second positioning push plate 86. The bottom of the second positioning push plate 86 is provided with a V-shaped opening 87 matching the rod body of the positioning rod 82, so that the positioning rod 82 can be smoothly inserted. Under the drive of the third air cylinder 85, the second positioning push plate 86 can move along the axial direction of the positioning rod 82, thereby realizing clamping and releasing of the flat aluminum pipe. The V-shaped opening 87 not only improves the stability of clamping, but also effectively prolongs the service life of the positioning rod 82 and the push plate by increasing the contact area and reducing stress concentration.

[0048] During the second bending and edge processing, the second bending and edge processing assembly 8 realizes the positioning and clamping of the flat aluminum pipe. First, the second air cylinder 81 drives the positioning rod 82 to move upward, so that the positioning block 83 is accurately inserted into the interior of the flat aluminum pipe; then, the third air cylinder 85 drives the second positioning push plate 86 to move downward, and through the cooperation of the V-shaped opening 87 and the positioning rod 82, the flat aluminum pipe is stably clamped. In the subsequent bending operation, the positioning block 83 and the second positioning push plate 86 work together to ensure the shape and size of the flat aluminum pipe during the bending process, and also facilitate the subsequent punching and material collecting operations.

[0049] In combination with Figure 4 , Figure 6 and Figure 9As shown, the pipe bender 7 includes a second servo motor 71 arranged on the workbench 1, the output end of the second servo motor 71 is connected with a bending wheel disc 72, the outer periphery of the bending wheel disc 72 is provided with a first groove 73 matched with the outer wall of the flat aluminum pipe rod body, one side of the bending wheel disc 72 is provided with a rotating seat 74, the rotating seat 74 is provided with a fourth cylinder 75, the output end of the fourth cylinder 75 is connected with a fixed block 76, the top end of the fixed block 76 is provided with a second groove 77 matched with the outer wall of the flat aluminum pipe rod body, the side of the rotating seat 74 is provided with a fixed seat 78, the fixed seat 78 is provided with a guide block 79, and the guide block 79 is provided with a third groove 791 matched with the outer wall of the flat aluminum pipe rod body.

[0050] Specifically, the pipe bender 7 is the core processing unit in the automatic pipe bender puncher, which can realize high-precision and high-efficiency bending processing of the flat aluminum pipe.

[0051] The second servo motor 71 can realize control of the rotation angle, speed and torque. The output end of the second servo motor 71 is connected with the bending wheel disc 72 through a shaft coupling, and the outer periphery of the bending wheel disc 72 is provided with a first groove 73 matched with the outer wall of the flat aluminum pipe rod body. The first groove 73 ensures that the flat aluminum pipe can deform along the preset trajectory during the bending process, which not only ensures the bending precision, but also avoids damage to the pipe caused by excessive extrusion.

[0052] On one side of the bending wheel disc 72, a rotating seat 74 is arranged. The rotating seat 74 rotates with the bending wheel disc 72 and fixes and clamps the flat aluminum pipe rod body during rotation. A fourth cylinder 75 is installed on the rotating seat 74, and the output end of the fourth cylinder 75 is connected with a fixed block 76. The fixed block 76 can move in a direction perpendicular to the axis of the flat aluminum pipe under the drive of the cylinder.

[0053] The top end of the fixed block 76 is provided with a second groove 77 matched with the outer wall of the flat aluminum pipe rod body. The design of the second groove 77 is in harmony with the first groove 73, which ensures that the flat aluminum pipe can be stably clamped between the bending wheel disc 72 and the fixed block 76 during the bending process.

[0054] On the side of the rotating seat 74, a fixed seat 78 stably supports a guide block 79. The third groove 791 provided on the guide block 79 is perfectly matched with the outer wall of the flat aluminum pipe rod body, which provides accurate guidance and positioning for the flat aluminum pipe before entering the bending area. And it provides a fixed direction opposite to the bending direction of the flat aluminum pipe during the bending process, so that the flat aluminum pipe is more stable during the bending process. Not only simplifies the installation process of the flat aluminum pipe, but also improves the efficiency and precision of the bending operation.

[0055] In the bending process, first of all, the second servo motor 71 drives the bending disc 72 to rotate to the preset angle, and at the same time, the fourth cylinder 75 drives the fixed block 76 to move upward, so that the second groove 77 is in close contact with the outer wall of the aluminum flat tube. At this time, the outer end of the aluminum flat tube is limited and fixed in the bending direction by the guide block 79, then the bending disc 72 and the rotating seat 74 continue to rotate under the drive of the motor, and through the cooperation of the first groove 73, the second groove 77 and the third groove 791, the aluminum flat tube is accurately bent. In this process, the clamping force between the bending disc 72 and the fixed block 76, the bending angle and the bending speed can be adjusted by setting the motor and the cylinder, so that the demand of different bending angles can also be realized.

[0056] In combination with Figure 3 , Figure 4 and Figure 5 , the feeding mechanism 2 includes a placing basket 21 arranged on the workbench 1, which can accommodate a sufficient number of aluminum flat tubes to meet the needs of continuous production. The placing basket 21 is provided with a protective fence around to prevent the aluminum flat tubes from accidentally falling during storage or handling, and is designed with an opening or gap for easy gripping by the robot hand to ensure smooth feeding. A mounting rack 22 is arranged above the placing basket 21, which provides a stable mounting platform for the subsequent mobile robot hand 23. The mounting rack 22 is installed with a mobile robot hand 23. The mobile robot hand 23 realizes the gripping and placing of the aluminum flat tube.

[0057] In actual operation, when the production line needs to be fed, the mobile robot hand 23 will start according to the preset program, first moving to the upper part of the placing basket 21, and positioning the aluminum flat tube to be grabbed by the high-precision sensor. Then, the gripper of the mobile robot hand 23 accurately probes and grabs the aluminum flat tube, and under the drive of the motor, the aluminum flat tube is smoothly and accurately transferred to the subsequent processing station.

[0058] In combination with Figure 3 , Figure 4 , Figure 7 and Figure 8 , the punching mechanism 4 includes a translation clamp 41 arranged on the workbench 1, which can realize high-precision and rapid positioning of the translation clamp 41 in the X-axis direction. The translation clamp 41 can be self-adapted according to the size of the aluminum flat tube to ensure stable clamping and accurate positioning of the aluminum flat tube during translation.

[0059] A punching assembly 42 is arranged behind the translation clamp 41, and a fixed clamp 43 is arranged on one side of the punching assembly 42. The fixed clamp 43 cooperates with the translation clamp 41 to complete the stable clamping of the aluminum flat tube during punching. During punching, the fixed clamp 43 can firmly clamp one end of the aluminum flat tube to prevent it from moving or deforming under the action of the punching force, thereby ensuring the accuracy and consistency of the punching.

[0060] In actual operation, when the flat aluminum pipe is accurately positioned to the punching station by the translation clamp jaw 41, the fixed clamp jaw 43 will quickly clamp one end of the flat aluminum pipe to ensure its stability during the punching process. Then, the flat aluminum pipe is subjected to accurate punching operation. After the punching is completed, the translation clamp jaw 41 will move the flat aluminum pipe to the next process, while the fixed clamp jaw 43 releases the flat aluminum pipe, preparing for the next round of punching operation. The punching assembly 42 includes a fixed plate 421 arranged on the workbench 1, which serves as the support basis of the entire punching assembly 42.

[0061] The fixed plate 421 is provided with a fixed groove 422 matching the profile of the bent flat aluminum pipe. The shape and size of the fixed groove 422 are consistent with the profile of the bent flat aluminum pipe, which is formed by numerical control machining technology to ensure that the flat aluminum pipe can be fitted after being placed. The two ends of the fixed groove 422 are provided with punchers 423, which are the core of the punching assembly 42 and can punch the flat aluminum pipe.

[0062] The fixed clamp jaw 43 is flush with the center of the top end of the fixed groove 422. The fixed clamp jaw 43 can quickly and accurately clamp or release the flat aluminum pipe. During the punching process, the fixed clamp jaw 43 and the fixed groove 422 work together to firmly fix the flat aluminum pipe at the predetermined position, preventing it from moving or deforming under the action of the punching force, thereby ensuring the accuracy and quality of the punching.

[0063] In actual operation, when the flat aluminum pipe is positioned to the punching station by the translation clamp jaw 41, the fixed clamp jaw 43 will quickly clamp one end of the flat aluminum pipe, cooperating with the fixed groove 422 to firmly fix the flat aluminum pipe at the predetermined position. Then, the two punchers 423 will start simultaneously according to the preset punching parameters to punch the two ends of the flat aluminum pipe.

[0064] Example 2:

[0065] Compared with Example 1, in combination with the drawings shown in Figure 3 , Figure 4 and Figure 9 , the material receiving mechanism 5 includes a fixed frame 51 arranged on the workbench 1, which serves as the mounting basis of the entire material receiving mechanism 5. The fixed frame 51 is provided with a mechanical clamp jaw 52, and one side of the fixed frame 51 is provided with a material receiving rack 53. When the flat aluminum pipe is completed and reaches the material receiving station, the mechanical clamp jaw 52 will quickly and accurately grab the flat aluminum pipe and move it to the material receiving rack 53 according to the predetermined path. The entire material receiving process is fast and efficient, and does not require manual intervention, greatly improving the production efficiency.

[0066] The above are only preferred embodiments of the present application, and it should be pointed out that, for those skilled in the art, without departing from the technical principles of the present application, a number of improvements and refinements can be made, and these improvements and refinements should also be considered within the scope of protection of the present application.
