[0033] The punching assembly 1 is provided with two groups, which process the two ends of the pipe fitting respectively. The punching assembly 1 includes a small punch 11, a first positioning device 12 and a first material return mechanism 13. The small punch 11 and the first positioning device 12 are both installed on the workbench 5, and the first material return mechanism 13 is fixedly connected to the front side of the small punch 11. The first positioning device 12 is provided on the rear side of the small punch 11. The small punch 11 and the first positioning device 12 are respectively arranged on the front and rear sides of the automatic transfer mechanism 3. The small punch 11 contains a customized die, which can punch the transferred workpiece. The first positioning device 12 is used to position the pipe fitting, and the positioning size can be adjusted to realize processing of different sizes. The punching assembly 1 is designed with a first material return mechanism 13, which is composed of a cylinder and a top plate. The top plate is acted by the cylinder to push the pipe fitting out after punching to complete the material return.

[0034] The chamfering assembly 2 is provided with two groups, which chamfer the two end holes of the pipe fittings respectively. The chamfering assembly 2 includes a chamfering machine 21, a second positioning device 22 and a second material return mechanism 23.

[0039] During the use of the utility model, when the control system is started, the special machine starts to work. After the front-end positioning device senses the workpiece and positions it, the stepping transfer starts to work. After the lifting cylinder 33 pushes the workpiece out of the support frame 34, the telescopic cylinder 32 sends the workpiece forward to the next process. After reaching the position, the two cylinders return to their positions, and the workpiece reaches the punching position. The positioning device of the punching assembly 1 presses the pipe fittings, and the punch press performs punching. After completion, the material is returned and the stepping transfer device works again to send it to the next process for chamfering. This cycle is repeated to complete the punching and chamfering process of the workpiece, and finally enters the visual inspection device for visual inspection. After passing the inspection, it can flow into the special material frame to complete the processing.
