Tungsten Carbide vs High-Speed Steel: Pontšo ea ho qetela ea lisebelisoa tsa ho sila Quill

Sebakeng sa ho sila ka nepo, khetho ea lisebelisoa tsa ho sila ka kotloloho e ama boleng ba machining le katleho. Carbide le high-speed steel (HSS), e le lisebelisoa tse peli tse ka sehloohong, e 'ngoe le e' ngoe e bontša litšobotsi tse ikhethang tsa ts'ebetso, e leng ho theha "filimi ea ho qetela" e tsotehang.

Papiso ea Ts'ebetso ea Boitsebiso 

Tungsten carbide, haholo-holo e entsoeng ka tungsten carbide e nang le cobalt joalo ka binder, e finyella ho thatafala ha HRA 88-93, modulus ea elastic e fihlang ho 600 GPa, le matla a hatellang a fetang 4,000 MPa. Ha ho bapisoa, HSS hangata e na le boima ba HRC 63-67, modulus elastic ea hoo e ka bang 200 GPa, le matla a hatellang a ka bang 2,500 MPa. Lintho tsena tsa mantlha li fa carbide monyetla oa ho tiea le ho hanyetsa ho roala.

Ts'ebetso e sebetsang ea Kopo 

Lits'ebetsong tse nang le karolelano ea bolelele ho isa ho bophara bo fetang 4: 1, li-quill tsa carbide li bonts'a melemo e ke keng ea nkeloa sebaka. Modulus ea tsona e phahameng ea elastic e tiisa hore, tlas'a maemo a tšoanang a mojaro, ho kheloha ke karolo ea boraro feela ea HSS. Sena se bohlokoa bakeng sa ho sila ho tebileng le ho sila ka hare ho cylindrical. Liteko tse sebetsang li bonts'a hore ha ho etsoa masoba a tebileng ho feta 150 mm, li-carbide quill li ka boloka liphoso tsa ho pota-pota ka har'a 0.005 mm, ha li-quill tsa HSS hangata li bontša ho kheloha ho fetang 0.02 mm.

Tlhahlobo ea Moruo 

Leha theko ea pele ea theko ea li-quill tsa mabili a carbide e phahame ka makhetlo a 3-5 ho feta ea li-quill tsa HSS, bophelo ba bona ba ts'ebeletso hangata bo bolelele ba makhetlo a 10-15. Mohlala, moleng oa tlhahiso ea likarolo tsa likoloi, ho fetohela ho li-quill tsa carbide nako e atolositsoeng ea phetoho ea lisebelisoa ho tloha ho lihora tse 8 ho isa ho lihora tse 120 le ho fokotsa sekhahla sa sekoli sa sehlahisoa ho tloha ho 3% ho isa ho 0.5%. Ha ho nahanoa ka nako ea ho theoha, litšenyehelo tsa basebetsi, le litefiso tsa lichelete, carbide e fana ka katleho e kholo ea moruo ka kakaretso.

Litlhahiso tsa Maemo a Kopo 

Li-quill tsa HSS li ntse li na le melemo libakeng tse ling:  

1. Ka lihlahisoa tse nyenyane, tse nang le phapang e phahameng, moo litšenyehelo tse tlaase tsa lichelete tsa pele li leng bohlokoa.  

2. Ha ho etsoa machining lisebelisoa tse thata tse atisang ho hahoa, HSS e fana ka thepa e ntle ea ho thibela ho khomarela.  

3. Bakeng sa lisebelisoa tse rarahaneng tsa ho sila, HSS e bonolo ho e kenya ka har'a libopeho tse khethehileng.

Mekhoa ea Tsoelo-pele ea Bokamoso  

Ka ho hlaha ha nano-grained carbide le lisebelisoa tse sebetsang tsa gradient, ts'ebetso ea carbide e ntse e tsoela pele ho ntlafala. Ho sa le joalo, HSS e boloka tlholisano ea eona libakeng tse ikhethileng ka theknoloji ea metallurgy ea phofo le lits'ebetso tse tsoetseng pele tsa ho roala. Lisebelisoa tsena ka bobeli li tla phela hammoho 'me li hole ka tsela e ts'oanang bakeng sa bokamoso bo bonoang, empa taolo ea carbide ho machining ea boleng bo holimo e tla tsoela pele ho matlafala.

Ho khetha thepa e nepahetseng ea ho sila ho hloka ho shebisisa litlhoko tsa machining, bophahamo ba tlhahiso le tekanyetso. Bakeng sa tlhahiso ea sejoale-joale, ho hahamalla ho nepahala le ho sebetsa hantle haholo, ha ho pelaelo hore carbide ke letsete le nang le molemo ho feta.

Haeba o hloka li-quill tsa ho sila, o amohelehile ho ikopanya le Khamphani ea Zhuzhou Better Tungsten Carbide.
