Description

A kind of method of titanium welding pipe production titanium vacuum cup
Technical field
The present invention relates to titanium insulation cup technology fields, and in particular to a kind of method of titanium welding pipe production titanium vacuum cup.
Background technique
For titanium as metal harmless to the human body, can now be implanted into human body safely becomes the advanced medical of human organ Material, titanium can also become the material of production vacuum cup.Come across at present the titanium vacuum cup in all kinds of exhibitions be essentially titanium without Slit-tube is made, but titanium seamless tubes yield is less, expensive, causes titanium vacuum cup production cost higher, it is difficult to produce in enormous quantities. Moreover, typically, cup material is thinner, and soaking time is longer, titanium seamless tubes are thicker, protected using the titanium of titanium seamless tubes production The heat insulation effect of warm cup is often bad.
Traditional technology maturation using stainless steel or titanium production vacuum cup, using one-to-two legal system cup, i.e., with one The welded tube of kind specification produces vacuum cup inside and outside shell simultaneously.Vacuum cup shell using bulging method production (inside and outside shell gap is about 5.5mm), since stainless steel welded pipe plasticity is good (elongation percentage is up to 53%), the bulging requirement of glass shell can be met.But titanium welding pipe The difference (elongation percentage is not less than 24%) of plasticity ratio stainless steel welded pipe, is difficult to realize the deformation requirements of cup shell or bulging often occurs The case where spalling, causes yield rate low, is unable to stable mass production.
Meanwhile vacuum cup is in the production process, material used in general sealing aspirating hole is solid glass glue, this method For metal and nonmetallic connection, metal and nonmetallic associativity is bad is easy to fall off causes vacuum cup gas leakage, to make to protect The warm cup lost of life.
Such as, 103405104 A of Chinese invention patent CN authorized, a kind of vacuum cup and its manufacturing method of titanium, Cup body is exactly made after bulging using the titanium tube of same specification, there is also the deformation requirements of cup shell difficult to realize or often There is the case where bulging spalling, the problem of causing yield rate low, be unable to stable mass production.Meanwhile after evacuation, it uses Solid glass glue is sealed sealing to through-hole (i.e. gas vent), and this method is metal and nonmetallic connection, metal and Fei Jin The associativity of category is bad to be easy to fall off, and vacuum cup gas leakage is caused, to make the vacuum cup lost of life.
In view of this, it is necessary to titanium vacuum cup production method in the prior art be improved, to solve the above problems.
Summary of the invention
When it is an object of the invention to solve in the prior art using titanium seamless tubes production vacuum cup, titanium seamless tubes deformation is easy Split, yield rate is low, is unable to the problem of stable mass production, provide a kind of side using titanium welding pipe production titanium vacuum cup Method.
Realize that the technical solution of goal of the invention is as follows: a kind of method of titanium welding pipe production titanium vacuum cup, comprising the following steps:
Step 1: making the shell of upper opening, the inner casing of upper opening of titanium welding pipe respectively, opens up pumping in outer casing bottom Hole;The caliber for making the titanium welding pipe of shell is greater than the caliber for making the titanium welding pipe of inner casing.
Step 2: being placed in interior of shell for inner casing, then will heal up after shell upper and the contraction distortion of inner casing top, will It heals up sealing welding, and titanium body of vacuum cup is made in the roll threading at sealing.
Step 3: titanium body of vacuum cup is put into vacuum drying oven, then the air in the interlayer that shell and inner casing are formed from It is extracted out in aspirating hole.
Step 4: in a vacuum furnace, sealed with brazing sealing is carried out to aspirating hole with solder, and keep the temperature in a vacuum furnace, made The solder for sealing the thawing of aspirating hole solidifies completely is made titanium vacuum cup first product.
Step 5: to the titanium vacuum cup first product polishing treatment in step 4, titanium vacuum cup finished product is formed.
In the preferred embodiment of the method for titanium welding pipe production titanium vacuum cup of the invention, titanium welding pipe thickness of pipe wall is 0.3 ~ 1.0mm。
