The carriage 18 is slidably connected to the first guide rail 21. The first driving cylinder 22 is installed on the equipment platform 11 and is used for driving the bearing seat 18 to slide along the first guiding slide rail 21, and a piston rod of the first driving cylinder 22 is fixedly connected to the bearing seat 18. The left support member 19 is fixedly mounted on the carriage 18, and the right support member 20 is slidably connected to the carriage 18 along a direction perpendicular to the first guide rail 21. A second driving cylinder 23 is mounted on the equipment table 11 for driving the right support member 20 to slide relative to the bearing seat 18. The piston rod of the second driving cylinder 23 is spaced from the right support 20. The finished frame 16 is mounted on the equipment table 11 on the side of the left support 19 away from the right support 20.

In operation, the left and right drive shafts 73, 76 rotate synchronously, and the first drive cam 81 moves the feed plate 79 to a position where the feed hole 82 communicates with the upper blanking passage 70. The rivets 13 dropped into the upper blanking passage 70 through the guide tubes 61 are introduced into the feed holes 82 of the feed plate 79. The feed plate 79 then moves to bring the rivets 13 of the feed holes 82 above the drop chute 71 so that the rivets 13 fall along the drop chute 71 onto the discharge plate 83 with the discharge holes not aligned with the drop chute 71. At this time, the left driving shaft 73 and the right driving shaft 76 are just rotated to a state where the left squeeze head 72 and the right squeeze head 75 are pushed toward the rivet 13, and the clinching of the rivet 13 is completed. The left driving shaft 73 and the right driving shaft 76 continue to rotate, the second driving cam 85 transmits force to the discharging plate 83 through the force transmission rod 87, and the discharging plate 83 moves to a position where the discharging hole is aligned with the discharging channel 71, so that the processed rivet 13 falls into the discharging drawer 62 along the discharging channel 71, and the process is completed.

Referring to fig. 3, in order to prevent the whole production system from overheating during operation, some heat dissipation fans 89 are installed on the side wall of the equipment platform 11. The heat radiation fan 89 exchanges air between the inside and the outside of the equipment table 11, thereby achieving a cooling effect.
