[0019] 2. In the present invention, when the two electric cylinders A drive the lifting plate to move downward, the punching and flanging head automatically punches the automobile air-conditioning pipeline; when the two electric cylinders A drive the lifting plate to slowly reset upward, and the servo motor A and the servo motor B are working, the punching and flanging seat drives the punching and flanging head to rotate eccentrically, and the automobile air-conditioning pipeline automatically flanging under the action of the chamfer of the punching and flanging head, the inner wall after the flanging is protruding contacts the eccentric circle formed by the punching and flanging head, and the outer wall after the flanging is protruding contacts the two clamping and positioning blocks, so that the automatic flanging after punching is realized, and the production efficiency of the automobile air-conditioning pipeline is improved;

When it moves to the punching and flanging position, the two electric cylinders A202 drive the lifting plate 203 to move downward, and the two pushing thin plates 207 push the two installation guide rods 402 to move inward at the same time, so that the two clamping positioning blocks 403 are automatically closed, and the punching and flanging head 304 automatically closes the automobile air-conditioning pipeline 6. Punching action: After punching, the two electric cylinders A202 reset the lifting plate 203. At this time, the servo motors A301 and B305 start to work, and the punching and flanging seat 303 drives the punching and flanging head 304 to rotate eccentrically. The automobile air-conditioning pipe 6 automatically flanging under the action of the chamfer of the punching and flanging head 304, and the inner wall after the flanging is protruding contacts with the eccentric circle formed by the punching and flanging head 304, and the outer wall after the flanging is protruding contacts with the two clamping positioning blocks 403, realizing the automatic flanging after punching; when the two electric cylinders A202 drive the lifting plate 203 to move upward, the two push thin plates 207 and the two installation The guide rod 402 is automatically separated, so that the two clamping positioning blocks 403 are automatically opened and closed under the action of the two return springs A405, which is convenient for the movement of the automobile air-conditioning pipeline 6; when the servo motor D508 is working, the hollow clamping tube 505 drives the automobile air-conditioning pipeline 6 to rotate, which is convenient for punching and flanging at different positions of the automobile air-conditioning pipeline 6, and also convenient for subsequent bending of the automobile air-conditioning pipeline 6 at different positions; when the automobile air-conditioning pipeline 6 moves to the bending position, the electric cylinder C704 is started first, and then the servo motor E701 is started, and the bending forming block A705 first contacts the automobile air-conditioning pipeline 6, and then surrounds the axis of the servo motor E701. Rotation realizes automatic bending of the automobile air-conditioning pipeline 6; the electric cylinder C704 and the electric cylinder D708 are started at the same time, and when the bending forming block A705 rotates around the axis of the servo motor E701, the bending forming block B710 automatically moves to the left under the action of the reset spring B711, which plays a limiting role on the automobile air-conditioning pipeline 6, ensuring that the automobile air-conditioning pipeline 6 is always closely fitted with the pipeline bending head 702 when bending the pipeline, thereby improving the bending accuracy of the automobile air-conditioning pipeline 6; when the servo motor E701 drives the connecting bracket 703 to reset, the bending forming block A705 can push the bending forming block B710 to automatically reset.
