[0047] It should be noted that, in this embodiment, the one-way screw 32 is driven to rotate by the second motor 31, thereby driving the L-shaped block 33 and the arc-shaped pressing plate 34 to move, so that the arc-shaped pressing plate 34 cooperates with the arc-shaped plate 11 to extrude the copper tube to form it.

[0048] For examples, please refer to the attached Figure 2-4 The pressing assembly 40 includes a second rack 43 slidably connected to one side of the top of the base 10, a push block 44 connected to one side of the second rack 43, a second gear 42 meshingly connected to one side of the second rack 43 and a first gear 41 meshingly connected to one side of the second gear 42, and one side of the first gear 41 meshingly connected to the first rack 35.

[0051] A first bevel 221 is disposed on one side of the top of the lifting block 22 , and the first bevel 221 matches with the second bevel 441 .

[0052] It should be noted that, in the present embodiment, the first bevel 221 cooperates with the second bevel 441 to facilitate the push block 44 to squeeze the lifting block 22 , thereby causing the lifting block 22 to descend.

[0053] For examples, please refer to the attached Figure 5 The fixing block 27 has limit rods 271 fixed on both sides. The limit rods 271 are slidably connected to the hole on one side of the L-shaped plate 53 . The top side of the limit rod 271 at the top is connected to the first motor 51 .

[0054] It should be noted that, in the present embodiment, the limiting rod 271 prevents the L-shaped plate 53 from rotating with the bidirectional screw rod 52 , and can support and fix the first motor 51 , thereby improving the stability of the bidirectional screw rod 52 .

[0056] Second T-shaped sliding grooves 13 are provided on both sides of the base 10 , and the groove bodies of the second T-shaped sliding grooves 13 are slidably connected to the T-shaped sliding blocks 431 .

[0057] It should be noted that, in this embodiment, the cooperation between the T-shaped sliding block 431 and the second T-shaped sliding groove 13 improves the stability of the second rack 43 and prevents the second rack 43 from being offset.

[0058] For examples, please refer to the attached Figure 5 The side of the clamping plate 54 close to the supporting ring 28 is an arc-shaped surface, and a rubber pad 541 is installed on the arc-shaped surface of the clamping plate 54.

The curved surface of the clamping plate 54 improves the stability of the copper tube.

[0060] For examples, please refer to the attached Figure 4 , the base 10 is provided with limiting slide grooves 14 on both sides;

[0061] The two sides of the L-shaped block 33 are fixed with limiting sliders 331 , and the limiting sliders 331 are slidably connected to the groove body of the limiting groove 14 .

[0062] It should be noted that, in this embodiment, the limiting sliding block 331 cooperates with the limiting sliding groove 14 to improve the stability of the L-shaped block 33 and prevent the L-shaped block 33 from rotating.

[0063] The specific operation mode of the present invention is as follows:

[0064] The present invention first inserts the copper tube into the support ring 28, and then drives the bidirectional screw rod 52 to rotate through the first motor 51, thereby driving the two L-shaped plates 53 and the clamping plate 54 to move in opposite directions, thereby achieving the clamping and fixing of the copper tube, and drives the unidirectional screw rod 32 to rotate through the second motor 31, thereby driving the L-shaped block 33, the first rack 35 and the arc-shaped pressing plate 34 to move, thereby causing the arc-shaped pressing plate 34 to squeeze the copper tube, and drives the first gear 41 to rotate through the movement of the first rack 35, thereby driving the second gear 42 to rotate, and then driving the second rack 43 and the push block 44 to move, thereby squeezing the lifting block 22 to make the lifting block 22 descend, thereby driving the support ring 28 and the copper tube to descend;

[0065] During the copper tube bending process, the first telescopic member 25 contracts and rotates with the rotating seat 24 to prevent the clamping end of the copper tube from bending or sliding. After the support ring 28 is reset with the lifting block 22, the staff pulls out the copper tube to achieve unloading.

[0066] 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.
