Ts'ebetso ea Tlhahiso ea Li-Quill tsa Tungsten Carbide: Ho Tloha Powder ho ea ho Precision Tool.

Li-quill tsa Tungsten carbide ke lisebelisoa tsa bohlokoa lefapheng la ho sila ka mokhoa o nepahetseng haholo, 'me ts'ebetso ea bona e ikhethang e bakoa ke mekhoa e metle ea tlhahiso. Leeto la ho tloha phofo ea boemo ba micron ho ea ho sesebelisoa se nepahetseng le kenyelletsa letoto la Ts'ebetso e laoloang ka hloko.

Karohano ea lintho tse tala le ho kopanya

Ho etsa tlhahiso ho qala ka phofo ea tungsten carbide e khethiloeng ka hloko le phofo ea cobalt. Cobalt e sebetsa e le karolo e kopanyang, 'me litaba tsa eona li ama ka ho toba ho thatafala le ho tiea ha sehlahisoa sa ho qetela. Ka tloaelo, litaba tsa cobalt li tloha ho 6% ho isa ho 12%, li lekantsoeng hantle ho latela litlhoko tse khethehileng tsa kopo. Li-powders tsena tsa boemo ba micron li tsoakoa ke metsi ka har'a mabili a bolo ho etsa bonnete ba hore kabo ea junifomo ea boemo ba limolek'hule.

Mokhoa oa ho theha

The slurry e tsoakiloeng e fafatsoa-ho omisoa ka har'a li-granules tse phallang mahala. Ka mor'a moo, ho sebelisoa theknoloji ea khatiso e batang ea isostatic ho hatella thepa ka khatello ea 200-300 MPa. Nakong ena, sebopeho sa motheo sa geometri sa shaft ea ho sila ea carbide se thehoa, empa matla a lula a le tlaase, a hloka ho sebetsa ho eketsehileng.

Sintering Process

Sintering ke ts'ebetso ea mantlha ea ts'ebetso ea tlhahiso. Liboping tsa vacuum sintering, mocheso o laoloa hantle ka holim'a sebaka se qhibilihang sa cobalt (hangata 1400-1500 ° C). Nakong ea mohato ona, karolo ea cobalt e qhibiliha ebe e kolobisa likaroloana tsa tungsten carbide, ho etsa maqhama a teteaneng a metallurgical ka ho phalla ha metsi. Taolo e nepahetseng ea curve ea ho futhumatsa le nako ea ho ts'oara ke ea bohlokoa ho netefatsa kholo e felletseng le kholo ea lijo-thollo tse laoloang.

Precision Machining

Sebaka sa ho sila sa carbide se se nang letho se kena mothating oa ho sebetsa ka nepo, se bohlokoa ho netefatsa hore quill ea ho sila e fihlela litlhoko tsa ts'ebeliso. Machining a benchmark a qala ho sebelisoa ho sebelisoa lisila tsa cylindrical tsa ultra-precision tse nang le mabili a silang a daemane ho theha axis e nepahetseng ea litšupiso, e nang le mamello ea boholo bo laoloang ka har'a ± 0.01 mm.

Mekhoa ea bohlokoa ea ho sila e kenyelletsa:

1. Ts'ebetso ea shank ea lisebelisoa: Ho sebelisa li-grinders tse nepahetseng tse phahameng tse nang le mabili a daemane, tse kenyelletsang ho sila ka thata, ho qeta halofo, le ho qeta. Ho sila ka thata ho tlosa lisebelisoa tse feteletseng, ho qeta halofo ho finyella litlhoko tsa mahlakore, 'me ho qeta ho tiisa hore ho na le bokaholimo ba Ra ≤ 0.2 μm. Mamello ea li-angle tsa taper bakeng sa HSK, CAPTO, le likhokahano tse ling li tlameha ho ba ka har'a ± 30”.

2. Ho sebetsana le lesoba le phodileng: Ho sebelisa lisebelisoa tsa ho phunya lesoba le tebileng ka theknoloji ea ho phunya lithunya. Ho netefatsa boleng ba lerako la lesoba, lebelo la phepelo (hangata 50-100 mm/min) le khatello ea sepholi (10-15 MPa) li tlameha ho laoloa ka nepo. Ho nepahala ha bophara ba lesoba ho tlameha ho fihla sehlopheng sa H7, ka phoso ea ho otloloha e sa feteng 0.02/100 mm.

3. Matla a ho leka-lekanya: Ho sebelisa mechine e khethehileng ea ho leka-lekanya ho lokisa kabo ea bongata ka ho tlosa thepa ka mokhoa o tšoanang. Litlhoko li kenyelletsa ho finyella tekanyo ea G2.5 ea ho leka-lekanya le ho se leka-lekane ho setseng ho ka tlase ho 1 g · mm / kg ka lebelo le phahameng la ho sebetsa.

Tlhahlobo ea Boleng

Tlhahlobo ea ho qetela e kenyelletsa ho hokahanya metjhini e lekanyang bakeng sa litekanyo tsa geometri, li-interferometer tsa laser bakeng sa sebopeho le mamello ea maemo, mechini e leka-lekaneng bakeng sa tlhahlobo e matla ea ho leka-lekanya, le li-microscopes tsa metallurgic bakeng sa tlhahlobo ea sebopeho sa thepa. Ke lihlahisoa feela tse fetang liteko tsohle tse thata tse ka tlisoang.

Ts'ebetso eohle ea tlhahiso e kopanya mahlale a mangata ho kenyelletsa metallurgy ea phofo, machining a nepahetseng, le kalafo ea mocheso. Taolo e nepahetseng mothating o mong le o mong ka kopanelo e kenya letsoho tšebetsong e ikhethang ea li-quill tsa tungsten carbide. Haholo-holo mohatong oa ho sebetsa ka nepo, ts'ebeliso e felletseng ea thekenoloji ea lisebelisoa tse thata haholo, theknoloji ea tekanyo e nepahetseng, le theknoloji ea taolo e ikemetseng e netefatsa ho nepahala ha tlhahiso ea boemo ba micron.

Khamphani ea Zhuzhou Better Tungsten Carbide e ka fana ka lisebelisoa tsa boleng bo holimo, tse nepahetseng tsa tungsten carbide. Emela lebitso la hau.
