Titanium-alloy special section and its production

Abstract

The invention discloses a kind of titanium alloy profile wire. The related tianium alloy profile wire is a board with multilayer titanium alloy hollow structure which involves interlayer with cooling slots. It is made up of the inner scale board with the thickness from 0.3mm to 1.0mm, the outer layer's titanium alloy board with the thickness from 0.3mm to 1.0mm, and the titanium alloy interlayer board with cooling slots between the above mentioned two boards. The molecule infilterating between layers forms a homogeneous matrix with no interface with the thickness from 2.0mm to 10.00mm.The process for manufacturing the board includes following steps: the manufacture of the mould, the preparing and manufacture of the board, installing and molding of the mould with rising temperature, diffusing connection, the first molding, the second molding, cooling and incising process border. It makes use of the technology of combination of SPF and DB, makes application of the technology of the dissolveable screw-demolding core in the investment casting production process. Through twice molding, it accomplishes the processing of the titanium alloy profile wire, makes it the functional material. It provides the aircraft's cabin with the material which has the cooling function under the assurance of the intensity and stiffness. It has a good perspective for its wide application.

Description

technical field

[0001] The invention relates to a titanium alloy shaped bar and a manufacturing method thereof. Background technique

[0002] As the aircraft is required to fly faster and faster, the cooling requirements of the aircraft shell are getting higher and higher, while the outer dimensions of the aircraft are required to be smaller and smaller, and the payload needs to be increased, which puts forward higher requirements for cooling efficiency.

[0003] Traditional aircraft shells are all solid panels, and a heat insulation layer is added on the inside or outside according to the different requirements of functional parts. The metal solid plate conducts heat as a whole, and the heat transfer speed is very fast. Contents of the invention

[0004] The technical problem to be solved by the present invention is to overcome the defect that the cooling effect of the existing aircraft shell is not ideal, and to provide a titanium alloy profile and its manufacturing met...

Examples

Embodiment Construction

[0016] 1. Mold design:

[0017] Considering the special structure of the cooling channel, the gas pressure cannot complete the molding at one time, so the water-soluble core needs to be designed. After the first molding is completed, the water-soluble core is dissolved with water, and then the secondary molding is performed to achieve the final design.

[0018] 2. Mold manufacturing

[0019] Use a high-pressure water cutting machine to accurately cut the unfolded material (the accuracy of the high-pressure water cutting machine produced by the American PA company is ±0.05), after pickling and drying, apply solder resist, and dry it for the second time. Stack 4 layers of titanium alloy plates with different thicknesses and weld process edges, inlet and outlet nozzles.

[0020] 3. Manufacture of core

[0021] Water-soluble materials are selected, and their profiles are processed by CNC machine tools, which meet the design requirements

[0022] 4. Cutting

[0023] By calculat...
