Abstract

The invention discloses a manufacturing process for a titanium alloy Huck rivet. The manufacturing process is characterized by comprising the steps of rivet body manufacturing and lining manufacturing, wherein rivet body manufacturing comprises the following steps that 1, a rivet body blank is prepared; 2, upsetting forming is carried out; 3, washing is carried out; 4, heat treatment is carried out, specifically, a, solid solution heat treatment is carried out, specifically, a washed rivet body semi-finished product is put into a vacuum water quenching furnace at the temperature of 800 DEG C -950 DEG C to be subjected to production heat preservation for 1.5 h - 2 h, and then water-cooled; b, aging heat treatment is carried out, specifically, the water-cooled rivet body semi-finished product is put into a vacuum furnace at the temperature of 550 DEG C - 600 DEG C to be subjected to heat preservation for 8 h -10 h, and then air-cooled; 5, turning is carried out, specifically, the headouter diameter and the tail end thread bottom diameter of the rivet body semi-finished product subjected to heat treatment are turned; 6, centerless grinding is carried out, specifically, the turned rivet body semi-finished product is put into a centerless grinding machine to grind the rod diameter, the head R angle and the head lower supporting surface; 7, thread rolling is carried out; and 8, surface treatment is carried out to obtain a rivet body finished product. The manufacturing process is high in machining efficiency and qualified rate, and the product is excellent in corrosion resistance, structural strength, surface hardness, structure uniformity and the like.

Description

technical field [0001] The invention relates to the field of production technology of new material rivets, in particular to a production technology of titanium alloy Huck rivets. Background technique [0002] At present, Huck rivets mostly use steel materials as raw materials for production, and the performance of products such as corrosion resistance, structural strength, surface hardness and tissue uniformity is relatively low due to the limitation of raw materials, and the weight of products is relatively heavy, which reduces its utilization rate. Contents of the invention [0003] Aiming at the defects in the prior art, the present invention provides a titanium alloy with high processing efficiency and qualified rate, excellent performances such as product corrosion resistance, structural strength, surface hardness and structure uniformity, light weight and improved product utilization rate. Gram rivet manufacturing process. [0004] The technical scheme that the pres...
