Description
Technical field
The present invention relates to a kind of titanium-alloy explosion-prevention material, especially be applicable to titanium-alloy explosion-prevention material of space flight and aviation field and preparation method thereof.
Background technology
In the storage-transport vessel of inflammable, explosive liquid state, gaseous state hazardous chemical, because of mishaies such as static, naked light, gunslinging are burnt, explosion hazard, need in storage-transport vessel, load a kind of netted explosion-proof lamp in order to prevent medium.Existing explosion-proof lamp prepares with aluminium alloy.This explosion-proof lamp long period of soaking is in vessel media, owing to the reason of material itself makes its range of application be subjected to certain restriction.In addition, present explosion-proof lamp generally adopts cut mechanically technology joint-cutting on tinsel, stretches then and makes, and cutting waste material that produces during cutting and particle are disadvantageous for the use of explosion-proof lamp.In sum, existing explosion-proof lamp material choose and processing technology aspect have some defectives, can not satisfy the application requiring of some special dimension.For example, space flight and aviation field have very strict requirement for the purity of fuel medium, and present aluminium alloy explosion-proof lamp can not satisfy the accumulating requirement for fuel medium of space flight and aviation field.
Summary of the invention
One of technical problem to be solved by this invention is, at the deficiencies in the prior art, provides a kind of titanium-alloy explosion-prevention material that is applicable to space flight and aviation field.The manufacturing process of this explosion-proof lamp comprises: titan alloy casting ingot → rolling titanium alloy paper tinsel → grooving machine joint-cutting → drawing and forming Web materials, said titanium alloy contains the metal of following quality %: molybdenum 2.8-3.8, preferred 3.0-3.5, more preferably 3.0-3.2, chromium 0.8-7.8, preferred 2.3-7.5, more preferably 3.5-4.5, nickel 0.6-0.9, aluminium 5.5-6.7, vanadium 3.6-4.3, surplus is a titanium.Said titanium alloy thickness is 0.05-0.15mm, preferred 0.07-0.10mm.
In order to strengthen the intensity of explosion-proof lamp, described titanium alloy also can contain metal zirconium 0.8-3.0%, and/or metal hafnium 0.5-1.0%, and/or metallic tin 1.5-2.8%.
Two of technical problem to be solved by this invention is, at the deficiencies in the prior art, provides a kind of laser cutting technique to be used for the joint-cutting of titanium alloy paper tinsel.Said laser cutting comprises that use can launch the device of laser beam, and this device emitted laser beam is substantially perpendicular to titanium alloy paper tinsel travel direction.Can not produce smear metal and particulate when carrying out laser lancing, need not lubricant yet.According to employed titanium alloy paper tinsel characteristic, as hardness and thickness, and according to the desired characteristic of processed ultimate product, by the angle of control device adjustment cutting ray and the length of joint-cutting.Can use 1 or many (3-5 platform) emission laser beam device arranged side by side simultaneously, they be regulated laser beam independently of one another, thereby can optionally on the titanium alloy paper tinsel, produce joint-cutting.
According to the preferred embodiment of the present invention, the device of these emission laser beams is ON/OFF separately, therefore can adapt to the titanium alloy paper tinsel band of different in width.The device of described emission laser (cutting means) can be connected with the glass fibre that the device of a generation laser pulse is fed.The energy that the device of these emission laser is launched can independently each other be adjusted.Required total power is 100-1000 watt, depends on the hardness and the thickness of institute's work material, and desired kerf width.This paper tinsel band that has with respect to the horizontal and vertical otch of foil travel direction can form metal net shaped coiled material by stretching device.Have perpendicular to the paper tinsel band of the cross sections of length direction draw when stretching not only broadened, and on travel direction, also can shorten simultaneously, cutting means that therefore is provided with by front and back in the production unit of processing continuously and couple together by same paper tinsel band and stretching device are formed and are cut-draw unit.
