Double-cone rhombic titanium alloy overall cabin manufacturing method

Abstract

The invention discloses a double-cone rhombic titanium alloy overall cabin manufacturing method. The method comprises the following steps: a double-cone rhombic cabin casting is molded based on graphite pouring and detected; a rhombic shell blank is formed by performing machining, standard measurement and the like for the double-cone rhombic cabin casting in sequence; a rough-machined rhombic shell is formed by roughly machining a shell appearance according to the rough machining reference after deviation of a coordinate system; the shell size of the rough-machined rhombic shell is detected; the form and location tolerance of the rough-machined rhombic shell is detected by the first form and location 3D scanning; the shell appearance of the rough-machined rhombic shell is finished based on the finishing reference; the shell size of the finished rhombic shell is detected; the form and location tolerance of the finished rhombic shell is detected by the second form and location 3D scanning; and the cover laser welding and the cabin heat treatment are performed for the finished rhombic shell. The method effectively solves the technical problem of difficult control of machining of a traditional double-cone rhombic titanium alloy overall cabin product, and guarantees the total quality of the double-cone rhombic titanium alloy overall cabin.

Description

technical field [0001] The invention relates to the field of large-scale machinery manufacturing, in particular to a method for manufacturing a biconical diamond-shaped titanium alloy integral cabin. Background technique [0002] With the upgrading of my country's aerospace products, the performance of weapon types such as penetration capability, precision strike capability, damage capability, range capability, and maneuverability has been improved, and the requirements for the integrity of structural parts, wall thickness, dimensional accuracy, and material properties are constantly increasing. Improvement, the demand for large biconical diamond-shaped integral titanium alloy components is increasing. Large biconical diamond-shaped integral titanium alloy components have the following characteristics: (1) The shell has large dimensions, thin walls, and weak rigidity; (2) The shell has deformation and shrinkage in casting, and the profile, wall thickness (3) There are many c...
