Structure positions ultra-thin titanium alloy sheet, obtains waveform accordion-like plate after the compacting of wrinkle punch-pin 4；
(3) the waveform accordion-like plate blank that a time is completed in taking-up, be put into straightening it is recessed in, with pressed convex after the completion of positioning
Molding is straight, obtains straight titanium alloy plate；
(4) it will be reentered into wrinkle mold repeatedly, to ultra-thin titanium alloy after 180 ° of overturning by the titanium alloy plate of straightening again
Plate carries out room temperature compression moulding, the waveform accordion-like plate after obtaining the second passage RCS；The wave that a time is completed in taking-up
Shape wave accordion-like plate blank, is put into straightening mold repeatedly, and straightening after the completion of positioning obtains straight titanium alloy plate；
(5) with the operating method of each passage in front, circulation repeatedly, is completed multi-pass wrinkle-straightening technique repeatedly, that is, is completed entire
The hydrodynamics technique of the ultra-thin titanium alloy sheet of multiple elements design flak jackets.
Beneficial effect
The present invention has the following advantages that compared with prior art.
It is an advantage of the invention that structure is simple, with conventional stamping die can common die, mode can replace, reduce
Manufacture and use cost, entire RCS simple process, room temperature forming, processing line is short out, enhances environmentally protective effect.
Detailed description of the invention
Below in conjunction with attached drawing, the invention will be further described.
Fig. 1 is the structure principle chart of involved multiple elements design flak jackets of the invention；
Fig. 2 is the die theory figure of wrinkle repeatedly used in the present invention；

Specific embodiment
It is a kind of for making the material of multiple elements design flak jackets, which includes ultra-thin titanium alloy sheet 2, as shown in Figure 1, institute
It states ultra-thin 2 two sides of titanium alloy sheet and is respectively equipped with ceramic wafer 1 and composite fibre ballistic fabric 3, the ultra-thin titanium alloy sheet 2 is wrinkle
Forming board.
It is a kind of for making the hydrodynamics method of the material of multiple elements design flak jackets, as shown in Figure 2,3, this method includes
Following steps:
(1) it is required according to the size of die size and shellproof target, ultra-thin titanium alloy sheet 2 is subjected to blanking, the ultra-thin titanium is closed
Golden plate 2 includes Ti-6Al-4V, Ti-5Al-2.5Sn, and the ultra-thin titanium alloy sheet 2 smears proportioned zinc stearate and machine oil is mixed
Object is closed, lubricating action is played；
(2) using wrinkle mold repeatedly, room temperature compression moulding is carried out to ultra-thin titanium alloy sheet 2, before wrinkle, passes through wrinkle cavity plate 5
Structure positions ultra-thin titanium alloy sheet 2, obtains waveform accordion-like plate after the compacting of wrinkle punch-pin 4；
(3) the waveform accordion-like plate blank that a time is completed in taking-up, is put into straightening recessed 7, with pressed after the completion of positioning
6 straightening of punch-pin, obtains straight titanium alloy plate；
