Embodiment 1

[0036] A blind rivet manufacturing process, including nail body manufacturing and nail sleeve manufacturing;

[0037] Nail body production includes the following steps:

[0038] Step 1, nail body blank preparation: select A286 raw materials with appropriate specifications and quality;

[0039] Step 2, upsetting and forming: the selected A286 raw material is passed through the mold of the corresponding specification in the cold pier machine to form the head, steps and rods of the nail body for three times to obtain the semi-finished nail body;

[0040] Step 3, cleaning: Put the semi-finished nail body into the corresponding cleaning line to remove the oil dirt and surface sandblasting caused by upsetting;

[0041] Step 4, heat treatment: put the cleaned nail body semi-finished product into a heat treatment furnace at 650°C for production and heat preservation for 10 hours, and then air-cool;

[0042] Step 5, thread rolling: rub the semi-finished nail body after heat treatment...
