Abstract

The invention discloses a self-plugging rivet manufacturing process. The self-plugging rivet manufacturing process comprises rivet body manufacturing and rivet sleeve manufacturing, wherein the rivetbody manufacturing process comprises the following steps of 1, preparation of rivet body blanks: selecting an A286 raw material with the appropriate specification and mass; 2, upsetting forming: conducting upsetting on the selected A286 raw material through molds with the corresponding specifications in a cold upsetting machine 2-3 times to form heads, steps and rod parts of rivets to obtain semifinished rivet bodies; 3, cleaning: feeding the semifinished rivet bodies onto a corresponding cleaning line to remove oil dirt and blasted surface sand generated after upsetting; 4, heat treatment: feeding the cleaned semifinished rivet bodies into a heat treatment furnace of 650-700 DEG C for production heat preservation for 8-10 h, and then conducting air-cooling; 5, thread rolling: conducting thread rolling on the semifinished rivet bodies subjected to heat treatment to form knurls, threads and grooves; and 6, surface treatment: conducting surface treatment on the semifinished rivet bodiessubjected to thread rolling to obtain finished products. The self-plugging rivet manufacturing process is simple in working procedure, high in machining efficiency and qualified rate of the products and good in quality.
