When the pipe plug reaches the specified position, the sensor on the end plate will be sensed and activate the operation of the small transfer device 62. The function of the small transfer device 62 is to transfer the pipe plugs to the plugging equipment.

[0039] The function of the small transfer device 62 is to transfer the pipe plug to the plugging equipment. It includes two groups of cylinders 621 and an adsorption device 622.

The end face positioning device is located at the other end of the punching to complete the size positioning. The position positioning device is a set of positioning mechanisms shared with the next tapping process. When the special machine is working, the cylinder on the first positioning device 12 acts on the positioning groove to press the pipe fitting to achieve fixation. A first material return mechanism 13 is designed on the punching assembly 1, which consists of a cylinder and a push rod. The push rod is acted by the cylinder to push the pipe fitting out after punching to complete the material return.

[0045] The tapping assembly 2 includes a tapping machine 21, a second positioning device 22 and a second material return mechanism 23. The tapping machine 21, the second positioning device 22 and the second material return mechanism 23 are all installed on the workbench 5 through a support, and a second material return mechanism 23 is provided on the lower side of the tapping machine 21.

[0047] The visual inspection mechanism 4 includes an external frame, a detection device and a sensor. The external frame is a translucent cover, which not only isolates outsiders from harm but also provides a light-gathering effect inside.

The middle positioning device is installed at the point where the punching and chamfering process at one end transitions to the punching and chamfering process at the other end, and is also used to position the pipe fittings for subsequent processing.

[0051] During the use of the present invention, all devices and mechanisms are controlled by the PLC system. The workpiece coming from the front is positioned on the positioning tooling. After the positioning is completed, the stepping transfer device transfers the workpiece to the plugging station through the action of the cylinder 621, and the plugging end face is positioned and the size position is fixed. The vibration disk 61 at the other end discharges the material, and the small transfer device 62 transfers the pipe plug into the mold cavity through gas adsorption. The motor 633 drives the mold cavity to rotate, and the pushing mechanism 631 starts to work and pushes the mold cavity forward for plugging. After completing the plugging on one side, the stepping transfer mechanism transfers it to the next plugging position for plugging another pipe fitting. The same method is used to transfer the workpiece for punching and tapping. Finally, it enters the visual inspection box for inspection. Qualified workpieces enter the material box to complete the processing.
