[0031] It should be noted that the three drive motors 132 are controlled by PLC elements to synchronously lift, which can make the first L-shaped plate 12 and the second L-shaped plate 13 stably lift, and can provide a larger pressure for the first L-shaped plate 12 and the second L-shaped plate 13, so that the riveting can be more tightly, and the first L-shaped plate 12 and the second L-shaped plate 13 respectively cooperate with the first riveting component 15 and the second riveting component 16, and simultaneously rivet the upper and lower riveting points of one corner of the fire damper shell;

[0032] Further, the three drive motors 132 are simultaneously started in the forward direction, driving the three bidirectional threaded rods 131 to synchronously rotate, and then through the nut connection of each group of threaded cylinders 123, the first L-shaped plate 12 is lifted and the second L-shaped plate 13 is lowered at the same time, pressing the upper and lower ends inside one corner of the fire damper shell;

[0033] Further, the two groups of first telescopic rods 153 are simultaneously extended, driving the two groups of riveting machines 151 and riveting plates 152 to respectively approach the first L-shaped plate 12 and the second L-shaped plate 13, and when the fire damper shell corner is pressed, the riveting machine 151 is started to rivet the riveting steel bars on the fire damper shell corner;
