[0035] like Figures 1 to 4As shown, the present embodiment proposes a punching device for a vehicle air-conditioning pipeline, comprising an upper mold 1 and a lower mold 2, wherein a first groove 11 is provided inside the upper mold 1, and a second groove 21 is provided inside the lower mold 2, wherein the positions of the first groove 11 and the second groove 21 correspond to each other, and the first groove 11 and the second groove 21 enclose a receiving cavity 3 for accommodating the pipeline to be punched. In addition, the punching device further comprises a first punch assembly 4 and a second punch assembly 5, wherein the first punch assembly 4 is arranged on one side of the lower mold 2, and the first punch assembly 4 can be used to bevel the pipeline 6, and the second punch assembly 5 is arranged at the bottom of the lower mold 2, and the second punch assembly 5 can be used to shape the pipeline 6 with an elliptical hole formed after the bevel treatment. In addition, a first through hole (not shown in the drawings) and a second through hole 22 are respectively provided on the lower mold 2, wherein the first through hole allows the first punch assembly 4 to extend into the receiving cavity 3, and the second through hole 22 allows the second punch assembly 5 to extend into the receiving cavity 3. In this way, the first punch assembly 4 is inserted into the first through hole to pre-bevel the pipe 6. The first punch assembly 4 can take away the cut aluminum chips during beveling. At the same time, the pipe 6 after beveling also provides convenience for subsequent pipe shaping, reducing the shaping area of ​​the pipe to be shaped; the second punch assembly 5 is inserted into the second through hole 22 to shape and expand the pipe 6 with the elliptical hole formed after beveling, and at the same time, the burrs on the pipe 6 can be removed, which greatly improves the punching efficiency. Since the second punch assembly 5 is arranged at the bottom of the lower mold 2, the aluminum chips generated at this time can automatically drip under the action of their own weight, avoiding the subsequent cleaning of the aluminum chips.

[0036] Preferably, the first groove 11 is arranged in an arc shape, and the second groove 21 is also arranged in an arc shape, and the first groove 11 and the second groove 21 are buckled to form an accommodating cavity 3 that is adapted to the shape of the pipeline 6 .

[0037] For further information, see Figure 1 and Figure 3 As shown, the first punch assembly 4 includes a first support 41, a first punch 42, and a first push cylinder 43. The first punch 42 is arranged on one side of the first support 41, and the first punch 42 can extend into the first through hole, and the first push cylinder 43 is installed on the other side of the first support 41, and the first push cylinder 43 can push the first support 41 to move. In this way, when the pipeline 6 is beveled, the first push cylinder 43 pushes the first support 41 to move, and the first support 41 drives the first punch 42 to move, so that the first punch 42 extends into the first through hole to bevel the pipeline 6.

[0038] Preferably, the end of the first punch 42 is arranged in an arc shape. Of course, in the embodiment, according to the actual situation and specific needs, the end of the first punch 42 can also be arranged in a V-shaped, elliptical shape, etc., which is not limited here.

[0039] Preferably, the first through hole is arranged below the center line of the to-be-punched pipe 6. By arranging the first through hole below the center line of the pipe 6, the pipe 6 can be easily beveled, so that the beveled pipe 6 is elliptical, and the first punch 42 is arranged at the bottom of the lower die 3, which is conducive to the first punch 42 to automatically drip aluminum chips during the beveling process, thereby reducing the subsequent cleaning process.

[0040] For further information, see Figure 3 As shown, the second punch assembly 5 includes a second support 51, a second punch 52 is provided on one side of the second support 51, and a second push cylinder 53 is provided on the other side of the second support 51. The second push cylinder 53 can be used to push the second support 51 to move. In this way, the second support 51 is pushed by the second push cylinder 53, and the second support 51 further drives the second punch 52 to move, so that the second punch 52 extends into the second through hole 22 to perform shaping and rounding processing on the pipeline 6.

[0041] For further information, see Figure 3 As shown, the second punch 52 includes a punch body 521 and a shaping portion 522, and the shaping portion 522 is arranged on one side of the punch body 521. By providing the shaping portion 522, the pipe 6 with an elliptical hole formed after the bevel processing can be shaped. Preferably, the punch body 521 and the shaping portion 522 are integrally formed. Through integral molding, subsequent machining can be simplified and machining efficiency can be improved.

[0042] Furthermore, a fan (not shown in the drawings) is provided on one side of the upper mold 1 or the lower mold 2. By providing the fan, aluminum chips in the accommodating cavity 3 can be removed. Preferably, the fan is arranged in the axial direction of the accommodating cavity 3, and by facing the axial direction of the pipeline 6, the aluminum chips in the accommodating cavity 3 can be effectively blown away, thereby improving the efficiency of removing the aluminum chips.

[0043] For further information, see Figure 2 As shown, the device further includes a blowing pipe 7, the blower is connected to one end of the blowing pipe 7, and a through hole is provided on the lower mold 2, and the other end of the blowing pipe 7 can be extended into the accommodating cavity 3 through the through hole. In this way, the blower quickly blows away the aluminum chips in the accommodating cavity 3 through the blowing pipe 7, and by providing the blowing pipe 7, the blowing direction of the blower can be guided to accurately align with the accommodating cavity 3, thereby reducing the occurrence of air volume loss.

[0044] Furthermore, the lower mold 2 is also provided with a sensor (not shown in the drawings) and a controller (not shown in the drawings), the sensor can be used to sense the motion trajectory of the second punch assembly 5, the controller can be used to receive the signal of the sensor and control the rotation of the fan, and the controller is electrically connected to the sensor and the fan respectively. In this way, when the sensor senses that the second punch assembly 5 extends from the second through hole, the sensor transmits the sensing signal to the controller, and at this time, the controller controls the fan to rotate, thereby removing the aluminum chips remaining in the accommodating cavity 3.

[0045] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the utility model.
