Description
Technical field
The present invention relates to a kind of manufacturing methods of stud, belong to stud and prepare manufacture field.
Background technique
For pure titanium because having many advantages such as that specific strength is high, anti-corrosion, heat resistance is strong, the application in every field is more and more wider
It is general, but its smelting technique is complicated, high production cost, therefore the price of titanium is expensive, largely limits the popularization and application of titanium.
With the continuous expansion of titanium application field, this contradiction is all the more highlighted.
Current stud rolling process is complicated, needs by melting twice, peeling, cogging, polishing, cause production cost compared with
It is high.
Summary of the invention
The technical problems to be solved by the present invention are: providing a kind of manufacturing method of the stud of lower production costs.
To solve above-mentioned technical problem the technical scheme adopted by the invention is that: the manufacturing method of stud, including walk as follows
It is rapid:
Step 1: choosing the round titanium tube that internal diameter is 80mm~100mm, inner surface pickling processes；
Step 2: titanium sponge is pressed into cylindrical electrode block, electrode block diameter is slightly less than titanium tube internal diameter；
Step 3: electrode block is packed into titanium tube, titanium tube both ends welded closure, so that electrode block is set to the airtight cavity of titanium tube
Interior, all material becomes the combination blank of an entirety；
Step 4: the combination blank after vacuumizing is put into heating furnace and heats, it is small for combining the vacuum degree of blank
In 0.01Pa, heating temperature is 1000 DEG C~1200 DEG C, and heating time is 2 hours~6 hours；
Step 5: the combination blank for completing heating process taking-up is rolled；
Step 6: carrying out stress relief annealing after rolling bar, annealing temperature is 350 DEG C~650 DEG C, and the time is 4 hours~6
Hour.
Assembly material need to be processed in strict accordance with design size, coating titanium tube with a thickness of 1mm~3mm, preferably 2mm, with
Guarantee the integraty of combination blank；The internal diameter of titanium tube is 80mm~100mm, beyond can not merge between this range titanium sponge；For
Facilitating the loading of electrode block, while guaranteeing product quality, the spacing between electrode block outer wall and titanium tube internal diameter is 0.2mm~2mm,
Preferably 1mm.
It is 1000 DEG C~1200 DEG C that ready combination blank, which is put into the heating temperature heated in heating furnace, heating
Time is 2 hours~6 hours, can not be occurred beyond this range diffusion bond.
In addition, the rolling elongation percentage of initial passage is not less than 20% when rolling in step 5.
The beneficial effects of the present invention are: passing through the letter for then rolling preparation stud by the direct briquetting of titanium sponge, Vacuum Package
Change processing technology, processing cost is reduced by 2/3 or more.
Detailed description of the invention
Fig. 1 is the production schematic diagram of present invention combination blank；
Marked in the figure: 1- titanium sponge electrode block, 2- titanium tube, 3- titanium plate end cap.
