摘要：

对连接扣的结构进行了分析，指出由级进模具生产连接扣的钣金部分，并在折弯过程中将轴同步安装至连接扣。为了除去冲孔时产生的毛刺，在级进模具中安装倒角器，利用上模的上、下移动驱动倒角器工作，从而实现倒角；在模具旁边安装振动盘，将预先准备好的轴自动传送至模具的指定位置，再由棘轮机构送至安装位置，最后用滑块将钣金件折弯，同时将轴安装到钣金件中。为了判断轴是否准确送到预定位置，在模具中设置感应器，当感应器检测到轴后，才向压力机发出继续工作的信号。在该级进模具中设置相关的机械机构，使模具增加倒角、校正、装配等功能，有利于实现自动生产。

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.
