Problems solved by technology

[0004] The technical problem to be solved by the present invention is to overcome the defects that the existing titanium alloy plates are solid structures, difficult to process, and heavy in weight, and provide a titanium alloy honeycomb plate and its manufacturing method, which can make superplastic formed The gas flows according to the specified gas path, forming a predetermined honeycomb structure in the middle of the multi-layered titanium alloy plates, which increases the rigidity of the honeycomb plate to more than 3 times that of ordinary standard plates, and increases the material utilization rate by more than 2 times. The processing time is only 1 / 10 of the original technology, and the material utilization rate of the present invention is as high as 80%. At the same time, when the same rigidity is achieved, the material thickness is only 2-3mm, and the weight reduction effect is very obvious

Embodiment Construction

[0015] 1. Mold design:

[0016] According to the thickness of the plate, the honeycomb structure, gas flow channel, blank holder amount and thermal expansion coefficient are designed.

[0017] 2. Mold manufacturing:

[0018] After the high-temperature alloy steel precision casting blank is selected, a domestic numerical control vertical machining center is used, with three coordinates and a horizontal axis, and the accuracy is ±0.01. CNC machining of mold surface, and test mold.

[0019] 3. Plate preparation:

[0020] Use a high-pressure water cutting machine to accurately cut the unfolded material. Use a high-pressure water cutting machine produced by the American PAR company with an accuracy of ±0.05mm. After pickling and drying, apply solder resist and dry it for the second time. Stack 3 or 4 layers of titanium alloy plates with different thicknesses and weld the process edge, air inlet nozzle and outlet nozzle.

[0021] 4. Install the mold and heat up to form

Abstract

A cellular Ti-alloy plate for missile is composed of two surficial Ti-alloy plate and a cellular Ti-alloy plate as sandwich. Its preparing process includes such steps as making mould, making raw plates, installing mould, heating, diffusing, forming cellular structure, cooling and removing technological edges. It has high rigidity and light weight.

Description

technical field [0001] The invention relates to a titanium alloy honeycomb panel and a manufacturing method thereof. Background technique [0002] According to the requirements of the technical and tactical indicators of the new-generation space weapon system, the call for weight reduction of aircraft structural parts is getting louder and louder. According to foreign literature reports, for every 10g weight reduction of space parts, the cost performance of the product will increase by 10,000 US dollars. [0003] At present, the domestic titanium alloy missile cabin is completed by a combination of titanium plate roll forming, welding, and calibration, or by direct CNC machining of forging blanks. The processing time is long, and the material utilization rate is only about 15%. In addition, due to The rigidity of the cabin requires a thickness of 8-10mm. The shell of the traditional missile cabin is made of about 8mm titanium alloy plate, which is a solid plate. The plate i...
