[0037] Example 5, please refer to Figure 1 As shown, this utility model is an automatic integrated riveting bolt device, including an upper die 1, a lower die 2, a punching device 4, an automatic feeding device 5, a riveting device 8, a bending device, and a strip 3.

Specifically, a progressive die is used, with the first station alternating between punching holes and punching protrusions, and the second station performing the sheet-out operation.

[0047] During this process, strip 3 is punched at the first station, then cut into pieces at the second station, and the punched workpiece is sent into the riveting die in the mold for riveting.

[0048] Bolt 12 is conveyed to the bolting step on the mold through the conveyor pipe. The material belt 3 transfers bolt 12 to the riveting step for riveting. Subsequently, pre-forming, forming, and cutting are performed to produce the finished product, thus improving production efficiency.

[0049] The punching equipment 4 first punches holes in the strip 3 at equal intervals. Then, the automatic feeding equipment 5 puts the bolts 12 into the holes of the strip 3. The laser detection equipment 7 checks whether the bolts 12 are in place. If they are in place, the strip 3 continues to move. The riveting equipment 8 rivets the bolts 12 onto the strip 3. Then, the strip 3 passes through two bending equipment in sequence. The bending equipment bends both sides of the strip 3 to form a support. Finally, the cutting equipment 11 cuts off the connection between the support and the strip 3 to form an independent finished frame 13.
