Abstract

The invention discloses a bulge type titanium alloy self-plugging rivet manufacturing technology. The technology comprises rivet body manufacturing, rivet sleeve manufacturing and driving ring manufacturing. The rivet body manufacturing includes the following steps of 1, preparing a blank; 2, performing tampering to obtain a semi-finished product; 3, cleaning and removing surface dirt and raw material coatings formed by tampering; 4, performing thermal treatment, wherein a, first-time thermal treatment is performed, the cleaned semi-finished product is placed into a thermal treatment furnace under the temperature of 680-720 DEG C for production, the temperature is kept for 10-20 min, and then post-air-cooling is performed; b, secondary thermal treatment, the semi-finished product obtainedafter air cooling is placed into a thermal treatment furnace under the temperature of 450-500 DEG C for heat preservation for 8-10 h, and then post-air-cooling is performed; 5, performing centerless grinding, wherein the semi-finished product obtained after thermal treatment is placed into a centerless grinding machine for rod diameter grinding; 6, rolling threads, wherein the ground semi-finishedproduct is rolled to obtain a thread and a ring groove; 7, performing surface treatment. The machining efficiency and the yield are high, the product corrosion resistance, structural strength, surface hardness, the tissue uniformity and other properties are excellent, the mass is low, and the product usage rate is increased.
