[0019] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following description is given in conjunction with the embodiments and the accompanying drawings.

[0020] Please refer to Figures 1 to 2, a thin-walled copper tube flattening and bending processing device, comprising a machine 1, a flattening device 2, a bending device 3, a feeding turntable and a transferring device 4, wherein the machine 1 is provided with a flattening device 2, a bending device 3, a cutting device 5 and a transferring device 4, wherein a copper tube is wound around the feeding turntable, and the feeding turntable is rotatably arranged on one side of the flattening device 2 of the machine 1, and a cutting device 5 is provided on the side of the flattening device 2 away from the feeding turntable; the flattening device 2 is provided with a copper tube leveling position, and the bending device 3 is provided with a copper tube bending position; the flattening device 2 and the bending device 3 are arranged side by side; the transferring device 4 comprises a transferring frame 41 and a transferring push rod 42, and the transferring frame 41 is provided with a copper tube transferring position, and the transferring frame 41 is movable between the flattening device 2 and the bending device 3, and the copper tube transferring position is selectively opposite to the copper tube leveling position or the copper tube bending position; the copper tube transferring position is provided with a transferring push rod 42, and the transferring push rod 42 moves along the length direction of the copper tube transferring position.

[0021] As can be seen from the above description, the beneficial effects of the present invention are as follows: during processing, the copper tube to be processed is fed into the copper tube leveling position of the leveling device 2 by rotating the feeding turntable. After being leveled by the leveling device 2, the copper tube continues to move to the transfer rack 41 of the transfer device 4; the copper tube is then cut into a specified length by the cutting device 5; the cut copper tube is transferred to a position opposite to the copper tube bending position of the bending device 3 as the transfer rack 41 moves. Under the push of the transfer push rod 42 on the transfer rack 41, the copper tube is fed into the copper tube bending position of the bending device 3 for bending processing. Compared with the traditional processing method that requires manual assistance in transfer, the cooperation of the transfer rack 41 and the transfer push rod 42 of the transfer device 4 can quickly feed the flattened copper tube into the bending device 3 for bending processing, thereby improving processing efficiency.

[0022] Furthermore, the leveling device 2 includes a leveling guide wheel and a leveling base. Leveling guide wheels are provided on both sides of the copper tube leveling position, and the leveling guide wheels are arranged on the leveling base at intervals along the length direction of the copper tube leveling position.

[0023] From the above description, it can be seen that the copper tube is leveled by the leveling guide wheels on both sides of the copper tube leveling position; after the copper tube is input into the leveling device 2, it enters and passes through the copper tube leveling position, and is pressed by the leveling guide wheels on both sides to straighten and level the curved part of the copper tube so that it can output a straight copper tube.

[0024] Furthermore, the leveling base includes a horizontal base 21 and a vertical base 23, and the leveling guide wheel includes a horizontal guide wheel 22 and a vertical guide wheel 24. The horizontal base 21 and the vertical base 23 are both provided with a copper tube leveling position, and the copper tube leveling positions of the horizontal base 21 and the vertical base 23 are opposite to each other in their respective length directions; the copper tube leveling position of the horizontal base 21 is arranged on a side of the horizontal base 21 parallel to the end face of the machine 1, and the copper tube leveling position of the vertical base 23 is arranged on a side of the vertical base 23 perpendicular to the end face of the machine 1; horizontal guide wheels 22 are provided on both sides of the copper tube leveling position of the horizontal base 21, and vertical guide wheels 24 are provided on both sides of the copper tube leveling position of the vertical base 23.

[0025] From the above description, it can be seen that the copper tube is comprehensively leveled in the horizontal and vertical directions through the cooperation of the horizontal base 21, the horizontal guide wheel 22, the vertical base 23 and the vertical guide wheel 24; after the copper tube is input into the leveling device 2, it first enters the copper tube leveling position of the horizontal base 21, and the horizontal guide wheel 22 presses and levelles both sides of the copper tube in the horizontal direction; then the copper tube continues to enter the copper tube leveling position of the vertical base 23, and the vertical guide wheel 24 presses and levelles both sides of the copper tube in the vertical direction.

[0026] Furthermore, the bending device 3 includes a bending base 31 and a bending assembly, and a copper tube bending position is provided on the bending base 31; a group of bending assemblies are respectively provided at both ends of the copper tube bending position, and the bending assembly includes a fixed guide wheel 32 and a rotating guide wheel 33; the fixed guide wheel 32 and the rotating guide wheel 33 are respectively provided on both sides of the copper tube bending position; the fixed guide wheel 32 and the rotating guide wheel 33 can rotate synchronously on the bending base 31 with the center of the fixed guide wheel 32 as the rotation center.

[0027] From the above description, it can be seen that after the copper tube is pushed into the copper tube bending position of the bending device 3 by the transfer push rod 42 on the transfer rack 41, it is bent by the bending components at both ends of the copper tube bending position; specifically, taking one end of the copper tube bending position as an example, a fixed guide wheel 32 and a rotating guide wheel 33 are arranged on both sides, and the copper tube is clamped between the fixed guide wheel 32 and the rotating guide wheel 33; as the rotating guide wheel 33 rotates along the circumference of the fixed guide wheel 32, one end of the copper tube is pressed by the rotating guide wheel 33 to form an arc bend consistent with the arc route moved by the rotating guide wheel 33, until the rotating guide wheel 33 rotates and no longer presses against the copper tube, the bent copper tube can be moved up and taken out.

[0028] Furthermore, the bending device 3 also includes a guide tube. A guide tube is provided on the side of the copper tube bending position of the bending base 31 close to the transfer rack 41. The length direction of the guide tube is consistent with the length direction of the copper tube bending position.

[0029] As can be seen from the above description, the design of the guide tube ensures that the input copper tube can accurately enter the copper tube bending position.

[0030] Furthermore, the bending device 3 also includes a fixing device, which is arranged in the middle of the copper tube bending position, and the fixing device is pressed against the copper tube at the copper tube bending position to fix it.

[0031] As can be seen from the above description, the copper tube is pressed and fixed by the fixing device provided in the middle of the bending position of the copper tube, thereby preventing the copper tube from deviating during the bending process and affecting the bending effect.

[0032] Furthermore, the fixing device includes a fixing clamp 34, and two fixing clamps 34 are respectively arranged on both sides of the bending position of the copper tube; the two fixing clamps 34 are movable along the length direction perpendicular to the bending position of the copper tube.

[0033] As can be seen from the above description, the copper tube is clamped and fixed by the fixed clamping blocks 34 that are clamped towards each other, so as to achieve the fixation of the copper tube during the bending process.

[0034] Furthermore, the bending device 3 also includes a blowing assembly, and the bending base 31 is provided with a blanking hole 36 consistent with the shape of the processed copper tube at the bending position of the copper tube; the upper end of one of the fixed clamps 34 is provided with a blanking block 35 protruding toward the other fixed clamp 34, and the blanking block 35 is provided with a blowing hole toward the blanking hole 36, and the blowing hole is connected to the blowing assembly.

[0035] From the above description, it can be seen that after the bending processing is completed at both ends of the copper tube at the copper tube bending position on the bending base 31, they are separated from the fixed clamping block 34 in the middle of the copper tube bending position; after the two fixed clamping blocks 34 are separated, the blanking block 35 blows air toward the blowing hole of the blanking hole 36, blowing the processed copper tube down into the blanking hole 36.

[0036] Furthermore, the bending device 3 also includes a first guide block 37 and a second guide block 38; multiple first guide blocks 37 and second guide blocks 38 are provided between the two ends of the copper tube bending position, and the first guide blocks 37 and the second guide blocks 38 are respectively arranged on both sides of the copper tube bending position.

[0037] As can be seen from the above description, through the design of the first guide block 37 and the second guide block 38, positioning is performed on both sides of the copper tube to ensure that the copper tube is accurately input into the copper tube bending position.

[0038] Furthermore, the bending device 3 also includes a connecting rod 39, an operating handle 310 and a rotating guide hole 311. The connecting rod 39 is connected to the rotating guide wheel 33, and the operating handle 310 is provided on the connecting rod 39; the rotating guide hole 311 is an arc-shaped hole with the center of the fixed guide wheel 32 as the center of the circle, and the lower end of the operating handle 310 is provided in the rotating guide hole 311.

[0039] As can be seen from the above description, by rotating the operating handle 310 along the rotating guide hole 311, the rotating guide wheel 33 can be rotated along the fixed guide wheel 32, thereby bending the end of the copper tube.
