Arc-shaped titanium alloy thin-walled part forming tooling and method

Abstract

The invention relates to an arc-shaped titanium alloy thin-walled part forming tooling and an arc-shaped titanium alloy thin-walled part forming method, belongs to a metal material forming mold and a use method thereof, and solves the problems of long processing period and high production cost of existing titanium alloy thin-walled parts. The arc-shaped titanium alloy thin-walled part forming tooling comprises a cylinder, four limit blocks, four positioning blocks and a plurality of wrapping tape components. When the forming tooling is used for forming, two arc-shaped thin-walled parts to be formed cover the outer surface of a cylinder, and are limited in the vertical direction by the four limit blocks and the four positioning blocks, then are tightly hooped by the plurality of wrapping tap components uniformly distributed along the vertical direction of the cylinder and are butted to form a complete cylinder. The forming method comprises cutting, pre-forming, assembling, fastening, heat setting and disassembling steps. The forming tooling provided by the invention is simple in structure and convenient to manufacture and use; the method provided by the invention can meet the forming demands of large-diameter titanium alloy thin-walled parts, avoids the traditional and complex long-cycle working procedures of welding, thermal expansion, cutting and the like, so that the production cycle is greatly shortened, and the production efficiency is greatly improved.

Description

technical field [0001] The invention belongs to a metal material forming die and a using method thereof, in particular to a forming tool and method for a titanium alloy arc-shaped thin-walled part. Background technique [0002] In the projectile structure, there are skin parts of different thicknesses, sizes and shapes. The skin is the main body covered by the cabin skeleton in the projectile structure. It bears the heat of the cabin, ensures the aerodynamic shape of the projectile, and the load bearing capacity and other important tasks. Skinned projectiles must withstand pressure when they are in flight. The biggest difficulty in skin production is to solve the tolerance problem of its shape and position. [0003] For aluminum alloy arc-shaped thin-walled parts with a wall thickness of less than 2.0mm, the existing forming method is to directly roll the shape and correct the shape, which can ensure the shape and position tolerances of the parts such as straightness and r...
