Abstract

The invention discloses a hot forging forming method for a titanium alloy aviation three-way elbow joint. The hot forging forming method comprises the steps of feeding, heating and upsetting (or bending), shot blasting, defect checking and polishing and repairing, polishing, spraying, heating and pre-forging, pre-forging and trimming, shot blasting, defect checking and polishing and repairing, polishing, spraying, heating and finish forging, finish forging and trimming and the like. The step-by-step progressive forging forming process is adopted, the material volume of each step is reasonablycalculated, the material deformation of each step is reduced, and a surface treatment process is added before each forming step, so that the generation of folding and cracks is further reduced.

Description

technical field

[0001] The invention relates to the technical field of titanium alloy forging and forming, in particular to a method for hot forging and forming of a titanium alloy aviation tee elbow joint. Background technique

[0002] At present, the common tees / elbow joints on the market are mostly made of stainless steel, carbon steel, copper, ductile iron and other materials, and their forming processes are mostly welding, casting, hydraulic expansion, hot pressing, etc. The material strength of the manufactured products , The organizational performance is far from meeting the requirements of aviation parts. In order to meet the technical specifications of aviation parts, titanium alloys are often used for aviation parts. However, due to the material properties of titanium alloys such as high elastic modulus and poor formability, and the structural characteristics of poor material fluidity due to uneven material distribution of tee / elbow joints, The hot forging process...
