[0003] In existing copper tube bending equipment, one end of the copper tube is fixed, and the other end is inserted into the bending assembly. A rotation drive component drives the bending assembly to rotate, causing the copper tube to bend. This type of copper tube bending equipment has a relatively limited range of bending angles and curvatures, and cannot change the bending angle and curvature, thus failing to meet diverse production needs.

Detailed Implementation

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some, but not all, of the embodiments of this utility model.

[0036] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0037] Example 1

[0038] refer to Figures 1 to 2 The bending mechanism provided in this embodiment includes a reference unit 1, a fixing unit 2, and a bending unit 3. The fixing unit 2 and the bending unit 3 are arranged around the reference unit 1. Specifically, the fixing unit 2 is located above the reference unit 1, and the bending unit 3 is located on one side of the reference unit 1. The fixing unit 2 serves to fix the copper tube to be bent, preventing displacement during the bending process and affecting the bending effect. During the bending operation, one end of the copper tube can be clamped and fixed by the feeding mechanism, and the feeding mechanism moves the copper tube to the position of the bending mechanism, so that the part of the copper tube to be bent abuts against the reference unit 1. The fixing unit 2 fixes the copper tube, and then the bending unit 3 pushes the copper tube to bend along the reference unit 1.

[0039] The bending unit 3 includes a bending component 31 and a first drive component 32 for driving the bending component 31 to rotate. The reference unit 1 includes a reference component 11 and a second drive component 12 for driving the reference component 11 to extend or retract. In some embodiments, the first drive component 32 and the second drive component 12 can be a drive motor or a drive cylinder. The reference component 11 includes a plurality of reference blocks 111 arranged sequentially along the driving direction of the second drive component 12. Each reference block 111 has a different size; specifically, the size of each reference block 111 decreases sequentially along the driving direction of the second drive component 12.

[0040] Understandably, using the reference block 111 as a reference, the bending component 31 is rotated by the first driving component 32, causing the bending component 31 to push the copper tube along the reference block 111 to bend, thus achieving bending of the copper tube at different bending angles. By driving the reference component 11 to extend or retract by the second driving component 12, the bending component 31 can correspond to reference blocks 111 of different sizes, thereby achieving bending of the copper tube at different bending arcs. Simultaneously, when the copper tube needs to be bent to a larger arc, the switching between reference blocks 111 of different sizes allows the copper tube to first undergo a small arc bend during the bending process, then gradually transition to a larger arc bend. This achieves a gradual bending process, effectively avoiding large arc bends in one step that could cause cracks in the copper tube, thus improving the quality of bending operations and product quality.

[0041] In some embodiments, the bending assembly 31 includes a pressing block and a telescopic drive cylinder for driving the pressing block to extend and retract, thereby adapting to the distance between the pressing block and reference blocks 111 of different sizes. Under the drive of the telescopic drive cylinder, the pressing block can push the copper tube to abut against the reference blocks 111 of different sizes.

[0042] In some embodiments, a first limiting portion 1111 is formed on the side of the reference block 111 facing the fixing unit 2, and a second limiting portion 1112 is formed on the side of the reference block 111 facing the bending unit 3. The first limiting portion 1111 and the second limiting portion 1112 are connected. The first limiting portion 1111 is straight, and the length of the first limiting portion 1111 of each reference block 111 can be the same or different. The second limiting portion 1112 is arc-shaped, and the radius of the second limiting portion 1112 of each reference block 111 is different. The degree of curvature of the arc of the second limiting portion 1112 with different radii is different. The smaller the radius, the greater the degree of curvature of the arc, and correspondingly, the greater the bending arc at the bend of the copper tube. By setting the second limiting portion 1112 to be arc-shaped, the second limiting portion 1112 can fit more closely to the shape of the bend of the copper tube, effectively controlling the bending arc at the bend of the copper tube, making the bending shape of each copper tube consistent, and improving the production quality of the product.

[0043] As a further optimization, a first limiting groove 1113 is provided on the first limiting part 1111, and a second limiting groove 1114 is provided on the second limiting part 1112, with the first limiting groove 1113 and the second limiting groove 1114 communicating with each other. Since copper tubes are generally cylindrical, the first limiting groove 1113 and the second limiting groove 1114 provided on the first limiting part 1111 and the second limiting part 1112 respectively can conform to the shape of the copper tube, so that the copper tube is confined in the first limiting groove 1113 and the second limiting groove 1114, which effectively improves the stability of the copper tube bending process, thereby improving the bending operation quality.

[0044] The bending mechanism of this embodiment uses a reference component as a reference. By rotating the bending component, the copper tube is bent, achieving bending at different angles. By extending and retracting the reference component, the bending component can correspond to reference blocks of different sizes, thereby achieving bending with different curvatures and meeting diverse production needs. By setting the second limiting part to an arc shape, the shape of the second limiting part can better fit the shape of the copper tube at the bending point, effectively controlling the bending curvature of the copper tube at the bending point and ensuring the consistency of the copper tube bending effect. By setting the first limiting groove and the second limiting groove, the stability of the copper tube bending process can be improved, thus improving production quality.

[0045] Example 2

[0046] As a further optimization of Example 1, refer to Figure 3 The fixing unit 2 includes a fixing block 21 and a third driving component 22 for driving the fixing block 21 to move up and down. In this embodiment, the third driving component 22 is a driving cylinder. Under the drive of the third driving component 22, the fixing block 21 moves downward and abuts against the copper tube, so that the copper tube abuts against the first limiting groove 1113 on the first limiting part 1111, thereby fixing the copper tube.

[0047] As a further optimization, a limiting support 23 is provided on the fixing block 21. The limiting support 23 is used to abut against the reference block 111. Specifically, the limiting support 23 abuts against both sides of the first limiting groove 1113. Since copper tubes are usually cylindrical, the fixing block 21 directly pressing against the copper tube may cause instability such as sliding or swaying. By having the limiting support 23 abut against the reference block 111, the stability of the contact between the fixing block 21 and the copper tube can be improved, which is beneficial to further improve the stability of the bending operation.

[0048] In some embodiments, a third limiting groove may be provided on the fixing block 21 at a position corresponding to the first limiting groove 1113, thereby limiting the copper tube between the first limiting groove 1113 and the third limiting groove, thereby achieving a more stable fixing effect and further improving the stability of the bending process.

[0049] Example 3

[0050] refer to Figures 4 to 7The bending device provided in this embodiment includes a feeding mechanism 100 and a bending mechanism 200 as described in Embodiment 1 or 2. The feeding mechanism 100 includes a first driving unit 101 and a first clamping unit 102 drivenly connected to the first driving unit 101. The bending mechanism 200 is located in the driving direction of the first driving unit 101. In some embodiments, the first driving unit 101 can be a robotic arm or a driving module. In this embodiment, the first driving unit 101 is a driving module, which can realize the movement of the first clamping unit 102 to any position. By driving the first clamping unit 102 to move through the first driving unit 101, the position of the copper tube on the bending mechanism 200 can be changed, thereby realizing the bending of different parts of the copper tube, which is more conducive to realizing diversified production.

[0051] During operation, the first clamping unit 102 clamps one end of the copper tube and moves the portion of the copper tube to be bent to the position of the bending mechanism 200, so that the portion of the copper tube to be bent abuts against the reference block 111. The fixing unit 2 moves downward and abuts against the copper tube, completing the fixing of the copper tube. Then, the bending assembly 31 pushes the copper tube to bend along the reference block 111. It should be noted that the first clamping unit 102 maintains its clamping of the copper tube throughout the bending process.

[0052] In some embodiments, a feeding conveyor belt can be provided below the bending mechanism 200. After the copper tube is bent, the first clamping unit 102 can directly release the bent copper tube, causing it to fall onto the feeding conveyor belt. The feeding of the copper tube is completed by the feeding conveyor belt, thereby improving production efficiency.

[0053] In some embodiments, the first clamping unit 102 includes a clamping assembly 103 and a fourth driving assembly 104 for driving the clamping assembly 103 to rotate. In some embodiments, the fourth driving assembly 104 can be a drive motor or a drive cylinder. Under the drive of the fourth driving assembly 104, the clamping assembly 103 can be rotated, thereby changing the orientation of the copper tube to be bent, enabling the copper tube to bend in different orientations during the bending process, realizing bending of different parts and orientations of the copper tube, further improving the versatility of the bending equipment, and making it more conducive to diversified production.

[0054] As a further optimization, the bending equipment also includes a correction mechanism 300 and a first transfer mechanism 400, the first transfer mechanism 400 operating between the correction mechanism 300 and the feeding mechanism 100. The correction mechanism 300 includes a vision inspection unit 301, a second clamping unit 302, and a second drive unit 303 for driving the second clamping unit 302 to rotate. In this embodiment, the vision inspection unit 301 is an industrial CCD camera.

[0055] In some implementations, a flat structure is provided at one end of the copper tube. This flat structure can be used for the installation or connection of the copper tube. The bending shape of the copper tube and the orientation of the flat structure usually have fixed production standards and requirements. Therefore, it is necessary to ensure the consistency of the orientation of the flat structure at the end of the copper tube during the bending process. The correction mechanism 300 can correct the copper tube before bending, so that the orientation of the flat structure at the ends of each copper tube remains consistent.

[0056] The specific implementation process is as follows: the copper tube is fed to the position of the correction mechanism 300, and the second clamping unit 302 clamps and fixes the copper tube. At this time, the flat structure at the end of the copper tube is exactly above the vision inspection unit 301. The vision inspection unit 301 identifies and detects the flat structure at the end of the copper tube and sends the detected orientation information to the second clamping unit 302. The second clamping unit 302 corrects the copper tube according to the acquired orientation information, causing the copper tube to rotate to the correct orientation. By correcting the orientation of the copper tube through the correction mechanism 300, the bending operation quality can be further improved, which is conducive to improving product consistency.

[0057] In some embodiments, the bending equipment further includes a feeding mechanism 500 and a second transfer mechanism 600, the second transfer mechanism 600 operating between the feeding mechanism 500 and the correction mechanism 300. The correction mechanism 300 may also include a first support frame, which is disposed between the vision inspection unit 301 and the second clamping unit 302, and can be used to place the copper tube. During operation, the second transfer mechanism 600 transfers the copper tube from the feeding mechanism 500 to the first support frame, and then the second clamping unit 302 clamps the copper tube and performs subsequent correction operations.

[0058] In this embodiment, the feeding mechanism 500 includes a feeding bin with an inclined surface at the bottom. A lifting component is provided at the bottom end of the inclined surface. The lifting component can lift the copper tube located at the bottom end of the inclined surface so that the copper tube is located at the top of the feeding bin for the second transfer mechanism 600 to pick up the material.

[0059] As a further optimization, the bending equipment also includes a positioning mechanism 700, which is located between the feeding mechanism 500 and the correction mechanism 300. A second transfer mechanism 600 operates between the feeding mechanism 500, the positioning mechanism 700, and the correction mechanism 300. The positioning mechanism 700 includes a second support frame and limiting components and pushing components located on both sides of the second support frame. During positioning, the second transfer mechanism 600 places the copper tube on the second support frame, and the pushing components push the copper tube to abut against the limiting components, thus achieving positioning of the copper tube. Positioning the copper tube using the positioning mechanism 700 improves the accuracy of the bending operation, thereby further improving the quality of production.

[0060] In some embodiments, the second transfer mechanism 600 includes a horizontal drive module and a first clamping member and a second clamping member driven by the horizontal drive module. The first clamping member and the second clamping member can move synchronously under the drive of the horizontal drive module. When the first clamping member is located at the position of the feeding mechanism 500, the second clamping member is located at the position of the positioning mechanism 700; when the first clamping member is located at the position of the positioning mechanism 700, the second clamping member is located at the position of the correction mechanism 300. By having the first clamping member and the second clamping member simultaneously operate between the feeding mechanism 500, the positioning mechanism 700, and the correction mechanism 300, the production efficiency can be effectively improved.

[0061] The bending equipment in this embodiment, by setting a bending mechanism, can bend copper tubes with different bending angles and curvatures, making it highly versatile. By driving the first clamping unit to move via the first driving unit, the position of the copper tube on the bending mechanism can be changed, thereby enabling bending of different parts of the copper tube and facilitating diversified production. By setting a fourth driving component to drive the clamping component to rotate, the orientation of the copper tube can be changed, thereby enabling bending of different parts and orientations of the copper tube, further improving the versatility of the bending equipment. By setting a correction mechanism, the bending operation quality and product consistency can be improved. By setting a positioning mechanism, the production quality can be further improved.
