Abstract：

The structure of connecting buckle was analyzed, and it was pointed out that the sheet metal part of connecting buckle was produced by progressive die and the shaft was installed into the connecting buckle synchronically during the bending process. Then, in order to remove the burr produced by punching, a chamfer was installed in the progressive die, which was driven by the up and down movement of upper die to achieve chamfering, and the vibration plate was installed next to the die. Furthermore, the pre-prepared shaft was automatically transmitted to the designated position of die, and then sent to the installation position by the ratchet wheel mechanism. Finally, the sheet metal part was bent by a slider, and the shaft was installed into the sheet metal part. In order to determine whether the shaft was accurately delivered to the predetermined position, a sensor was set up in the die. When the sensor detected the shaft, a signal to the press to continue working was sent. The relevant mechanical mechanisms were set up in the progressive die to add the functions such as chamfering, correction and assembly, which was beneficial for realizing the automatic production.
