Description
Technical field
The present invention relates to powder metallurgical technology, specifically a kind of manufacture craft that adopts PM technique to produce the non-ball three-way connection of optical communication.
Background technology
The non-ball three-way connection of a product that the optic communication industry adopts, such as Fig. 1, material is stainless steel, the processing mode that before adopts is machined, during with the Vehicle Processing mode, 10 procedures is arranged approximately, uses artificial 10, approximately 1000 of overall output per manshifts.Because the material that Vehicle Processing is adopted is for excellent in fact, the weight before the processing is 3 times of the rear finished weight of processing, and waste of material is serious; The batch production machining accuracy is unstable, and the burr that Vehicle Processing produces is the difficult problem of the whole industry of puzzlement, time and effort consuming; Operation is many, and precision is high, and the production process check is difficulty, and operating personnel's technical ability is had relatively high expectations, and can't effectively guarantee product quality, and scrappage is higher, is not suitable for producing in enormous quantities, can't meet the need of market.
Summary of the invention
For above problem, the object of the present invention is to provide the manufacture craft of the non-ball three-way connection of a kind of optical communication, be existing machining accuracy instability problem when solving the machined production in enormous quantities with powder metallurgy (MIM) technique, to raise the efficiency, reduce cost.
Technical scheme of the present invention is achieved in the following ways: the non-ball three-way connection of a kind of optical communication in weight portion, may further comprise the steps: 1) batching, 2) injection moulding, 3) extraction, 4) sintering; It is characterized in that:
1), batching: get: 82 parts of powder of stainless steel; 8.9 part wax, 3.2 parts of polypropylene, 7.8 parts of low-pressure polyethylenes, 5.5 parts of thermoplastic elastomer (TPE)s; First powder of stainless steel and wax are added high mixer, the 630rpm stirring at low speed, heat to 65 ℃ and add again polypropylene, low-pressure polyethylene and thermoplastic elastomer (TPE), mix and continue agitating heating, make temperature be controlled at 190 ℃, time is controlled at 20-30 minute, after the discharging with composite material stripping and slicing, cooling, fragmentation, pack, store for future use;
2), injection moulding: above-mentioned composite material is formed blank by injection machine by mold injects, and its technical conditions are: mold temperature is controlled at 40 ℃, injection temperature: 183 ° in a district, 178 ° in two districts, 177 ° in three districts, 168 ° in four districts; Injection pressure 74MPa, injection speed: 65g/s, inject time: 2s; Cool time: 1s before the storage, 8 ± 3s after the storage;
3), extraction: will inject blank, to put into purity be 99.9% trichloroethylene solvent, and addition is as the criterion to cover blank 10-20mm, is incubated 5-6 hour under 50-60 ℃ temperature;
4), sintering: will extract good injection blank and put into the vacuum sintering furnace sintering:
(1) the injection blank is placed on the alumina ceramic plate, leaves each other certain slit, avoids being pasted together in the sintering process; Avoid directly contacting with graphite boxes or graphite cake;
(2) pass into inert gas shielding in the sintering process, pass into nitrogen when 1-800 ℃ of low-temperature sintering, flow-control passes into argon gas at 5-30pa when 1000-1330 ℃ of high temperature, and flow-control is at 10-30pa;
(3) sintering temperature arrives 1330 ℃ of insulations 3 hours, and insulation naturally cools to below 1000 ℃ after finishing, and applying argon gas starts blower fan, and temperature is down to below 80 ℃ and is come out of the stove, and is the non-ball three-way connection of optical communication communication.
The present invention has simplified technique, the high conformity of product, and in the controlled model at 0. 05mm of dimensional accuracy of the present invention is same, and size Control is stable, and follow-up assembling speed efficient improves more than 70%, is better than other manufacture method.
