In addition, in the process of double-sided countersunk head riveting of wedge-shaped parts, there will also be situations where the rivet cannot fill the pier head socket.
因此，传统的压铆装置已经难以胜任楔形件的铆接工作，必须针对楔形件来设计一种全新的压铆装置。Therefore, the traditional riveting device is difficult to do the riveting work of the wedge, and a new riveting device must be designed for the wedge.

步骤八：再次启动压下缸3，控制压下缸3的活塞杆下行，直到上压头8完成对铆钉的施压，当压下缸3的活塞杆下行到最大行程位置后，继续保压一段时间；Step 8: Start the pressing cylinder 3 again, and control the piston rod of the pressing cylinder 3 to go down until the upper pressing head 8 completes the pressure on the rivet. When the piston rod of the pressing cylinder 3 goes down to the maximum stroke position, continue to maintain the pressure a period of time;
步骤九：控制压下缸3的活塞杆退回到初始位置，铆接完成。Step 9: Control the piston rod of the pressing cylinder 3 to return to the initial position, and the riveting is completed.
