Ukukhuluma Ngokusetshenziswa Kwensimbi Ye-Tungsten Ekwenzeni Isikhunta

---

I-beam yohlaka ekwakhiweni, ukwakha ifaka ukusetshenziswa okujwayelekile kwe-Cr12MoV, indawo yayo kulula ukukhiqiza "isiqephu se-aneurysm clipping", okuholela kugongolo kanye namamaki ahlukene angaphezulu, ukunciphisa umthamo wokuthwala ugongolo, ukuze ukuxazulula le nkinga, ngokusebenzisa ucwaningo oluningi, sithole ukuthi insimbi ye-tungsten isetshenziswa kufa, kodwa singagwemi inqubo yokwenza ishidi bese ufaka "i-adhesion", ukuxazulula "isiqephu se-aneurysm clipping" , nensimbi ye-tungsten akulula ukuyigqoka, ukuthuthukisa ukuzinza kanye nempilo yesevisi ye-die, izinga eliphezulu lemikhiqizo.

Uhlaka lwefreyimu (ingxenye) luyingxenye ebalulekile yomhlangano wefreyimu ukuze kuqinisekiswe ukuqina kwe-torsional yefreyimu futhi ithwale umthwalo we-longitudinal. Ngokuthuthuka okuqhubekayo kwekhwalithi yemoto yonke, ikhwalithi ye-frame beam ibaluleke kakhulu. Ukuze uvimbele amandla omhlangano wefreyimu ukuba angancishiswa ngenxa yokukhubazeka kwekhwalithi ye-beam, kuyadingeka ukuthuthukisa ikhwalithi ye-beam.

Ukukhubazeka kwekhwalithi yezingxenye kanye nokuhlaziywa kwezimbangela zabo

(1) Ukukhubazeka kwekhwalithi yezingxenye. 

I-side strain ibucayi kakhulu, futhi imibandela iboniswa kuThebula 1.

Ithebula 1 Amazinga okuhlolwa kokuklwebheka

Grade	Izinga Lokwahlulela
V1	Ukuxubha okukhulu kuno-0.3mm
V2	Uma ubukhulu bukhulu kuno-0.2mm futhi bungaphansi kuka-0.3mm, futhi ibanga lokukhetha lingaphansi noma lilingana no-100mm
V3	Ibanga lokukhetha lingaphansi noma elilingana no-0.2mm, ibanga lokukhetha likhulu kuno-0.2mm nangaphansi kuka-0.3mm 100mm noma ngaphezulu futhi ipholishwe kahle
Note	I-V2 ingakhishwa ngokwezinga le-V3 ngemuva kokuthi ingxenye epholishiwe ipholishwe ishelele, futhi indawo epholishiwe kufanele ishelele. Ngaphezulu kwepuleti lensimbi kanye nesilinganiso sobubanzi nokujula asikho ngaphansi kuka-6:1

Umfanekiso wesi-2 ukhombisa umphumela wokusetshenziswa kokufakwayo kwe-Cr12MoV ukwakha izingxenye.

Umfanekiso wesi-2 ukhombisa umphumela wokusetshenziswa kokufakwayo kwe-Cr12MoV ukwakha izingxenye.

Imiphumela yokuhlolwa komkhiqizo:
I-strain igxile kakhulu ekugobeni ezinhlangothini zombili, futhi ukujula kwe-strain kungu-0.5 ~ 0.9mm.

(2) Izimbangela zokukhubazeka ezingxenyeni.

Ngesikhathi senqubo yokwenza isikhunta sengxenye, ngenxa yokushelela kwesihlobo phakathi kobuso bengxenye kanye nobuso besikhunta se-convex ne-concave, isikhunta se-convex, isikhunta se-concave kanye nengxenye yakha i-pair of friction pairs, ekhiqiza ngokuqhathaniswa. ukucindezeleka okukhulu kwemishini endaweni yokuxhumana (ikakhulukazi inqubo yokukhiqiza). Lapho ingxenye ingena emgodini wesikhunta, ingxenye: i-concave die mouth), okwenza izingxenye ezincane ze-convex zezindawo zokungqubuzana zikhubazeke ngokunwebeka noma ngokwepulasitiki, okuholela ekuqinisweni okuncane noma okuncane kwamabhondi e-athomu ezindaweni ezimbili. izinhlangothi. Lolu hlobo lwesayithi lubizwa nge-cold welding. . Lapho ipheya yokungqubuzana inyakaza ngokuhlobene, ngenxa yokuthi amabhondi e-athomu amahle endaweni engaphezulu kwezinhlangothi zombili azihlangani komunye nomunye, impahla idluliswa isuka kolunye uhlangothi lwepheya yokungqubuzana iye kolunye, yenze isibopho sensimbi, futhi ukuqongelela amaqhuqhuva. Uma ingaphezulu lepheya lokungqubuzana liqinile, into ehlanganisa insimbi cishe izokwakhiwa, okuzokwenza ukuthi ingxenye ibe nzima.

3 Ukukhethwa kwezinto ezibonakalayo zokufa kanye nezici zensimbi ye-tungsten

3.1 Ukukhethwa kwempahla yokufaka idayizi

Ngokuhlaziya ingxenye yesici, ukukhethwa kokufaka amafa kudlala indima ebalulekile ekuxazululeni izingxenye zamamaki okudonsa. Lokhu kudinga idayi ene-coefficient ephansi ye-friction, i-thermal conductivity ephezulu, nobulukhuni obuphezulu. Ngemva kokuqhathanisa izinto zokwakha, izinto ezintathu Ukuhlaziywa kokusetshenziswa kwensimbi ye-tungsten YG8 ekugcineni kwakhethwa. Ukuqhathaniswa kwezinto ezintathu kuboniswe kuThebula 2.

Material	I-Coefficient yokushayisana	Ukuqhuba kwe-thermal (W/m·k)	Ukuqina kokwelashwa kokushisa (HRC)	Note
I-Cr12MoV	0.15 ~ 0.3	45	56-60	Ubulukhuni obuphansi ngaphambi kokwelashwa kokushisa, Ukuqina kwanda ngemva kokwelashwa kokushisa
Ithusi leBeryllium (CB-2H)	0.006 ~ 0.01	100 ~ 110	42 ~ 48	Asikho isidingo sokwelashwa kokushisa
Insimbi yeTungsten (YG8)	0.005 ~ 0.008	59 ~ 88	69 ~ 82	Asikho isidingo sokwelashwa kokushisa

3.2 Izici zensimbi ye-tungsten

Insimbi ye-Tungsten inochungechunge lwezakhiwo ezinhle kakhulu njengokuqina okuphezulu, ukumelana nokugqoka, amandla amahle nokuqina, ukumelana nokushisa nokumelana nokugqwala, ikakhulukazi ubulukhuni bayo obuphezulu nokumelana nokugqoka, okuhlala kungashintshile ngisho nasezingeni lokushisa elingu-500 ° C. Isenokuqina okuphezulu ku-1,000°C.

4 Izinyathelo zokuqapha zokufakela kanye nokucutshungulwa kokufakwa kwensimbi ye-tungsten

4.1 Ukufakwa kwensimbi ye-tungsten

I-strain engxenyeni ikakhulukazi ikhona ku-arc yohlangothi, ngakho-ke kwanqunywa ukusebenzisa insimbi ye-tungsten kuphela ku-arc yesikhunta. Ukuqina kwensimbi ye-tungsten kungokwesibili kuphela kwedayimane, ayikwazi ukugaywa futhi ingacutshungulwa kuphela ngokugaya. Umumo kufanele uphonswe ngokunemba, futhi indawo ehlangene igaywe ngesondo ledayimane ukuze kugwenywe imicu
umgodi. Ukufakwa kwesikhunta se-concave esibalulekile kugxilile emzimbeni wokuphonsa ohlangothini, futhi i-carbide enosimende ishumekwe ekufakweni okubalulekile ngendlela ye-dovetail groove. Le ndlela yokulungisa ixazulula inkinga yokungakwazi ukubhola nokukhipha izimbobo ezinentambo ku-carbide enosimende.

4 ebonisiwe.

4.2 Izinyathelo zokuqapha zokucubungula ukufaka insimbi ye-tungsten

(1) Izinto ezidinga ukunakwa ngesikhathi sokusika nokugaywa.

• a. Insimbi ye-Tungsten ijwayele ukuqhekeka kanye nokuqhekeka ekhoneni ngaphansi komthelela kanye nomthwalo wokucubungula owedlulele. Kufanele iqiniswe ku-worktable ngaphambi kokucubungula.
• b. Izakhiwo kazibuthe zensimbi ye-tungsten ziphansi kakhulu. Ungasebenzisi omagnethi ukulungisa i-carbide enosimende. Sicela uyilungise ngethuluzi lamathuluzi. Sicela uqinisekise kabusha ukuthi i-workpiece ikhululekile yini ngaphambi kokucubungula. Uma kunjalo, lungisa i-workpiece ibe isitobhi esiqinile.
• c. Indawo ecutshunguliwe yensimbi ye-tungsten ngemuva kokusika nokugaya izoba bushelelezi kakhulu, futhi amakhona abukhali kakhulu, sicela unake ukuphepha lapho uphatha futhi usebenzisa.
• d. Insimbi ye-Tungsten iyinto enobulukhuni obuphakeme kakhulu kanye nokuqina. Akuvunyelwe ukushaya i-alloy eqinile ngesando sensimbi uma wesaba umthelela.

(2) Izinto ezidinga ukunakwa ngesikhathi sokukhishwa nokusika ucingo.

• a. Insimbi ye-Tungsten inobulukhuni obuphezulu kanye nokumelana nokugqokwa okuphezulu, futhi inqubo yokusebenza ihamba kancane ngesikhathi sokuphuma nokusika ucingo.
• b. Insimbi ye-Tungsten ijwayele ukuqhekeka nasemakhoneni ngemuva kokucutshungulwa kokukhishwa kukagesi, ngakho-ke sicela ulungise inqubo yokucubungula ngokuya ngemibandela yokusetshenziswa komkhiqizo.
• c. Insimbi ye-Tungsten ivamise ukuqhekeka ngesikhathi sokusika ku-inthanethi, ngakho-ke sicela uqinisekise ukuthi akukho sici endaweni ecutshunguliwe ngemuva kokucubungula ngaphambi kokudlulela kunqubo elandelayo.

5 Umphumela wezingxenye ngemuva kokusebenzisa isikhunta sensimbi ye-tungsten

Ngemuva kokuthi inkampani yethu yamukele isikhunta sensimbi ye-tungsten:

• (1) Ukucindezela ohlangothini lwe-workpiece kuyaqedwa njengoba kuboniswe kuMfanekiso 5.
• (2) Kwatholakala umphumela ongalindelekile, futhi kwatholakala ukuthi imibimbi ye-arc yangaphandle iyancipha. Lokhu kwahlaziywa. Ngenxa yokuthi insimbi ye-tungsten inobulukhuni obuphezulu kanye nobulukhuni obuhle obubomvu, ingafinyelela ku-900～1,000℃, futhi ngeke ibole lapho igcinwa ku-60HRC. Ngale ndlela, ngisho nalapho impahla igeleza, ingxenye izokhiqiza i-elastic and plastic deformation, ezothinta ukufaka. Ngokucindezeleka okunamandla, igebe phakathi kwesikhunta se-convex ne-concave ngeke sishintshe, futhi ukusetshenziswa okuqinile kwe-arc yangaphandle ye-workpiece kunganciphisa imibimbi.

Amazwi okuphetha ayi-6

Selokhu yamukelwa isikhunta sensimbi ye-tungsten, inkampani yethu iye yathuthukisa izinga eliphezulu lezingxenye, yathuthukisa ukuzinza kwekhwalithi yezingxenye, yandisa ukuphila kwesikhunta, futhi yandisa umjikelezo wokugcinwa kwesikhunta, ngaleyo ndlela yehlisa izindleko zokukhiqiza. kanye nokuxazulula inkinga yezingxenye zamapuleti aminyene. Inkambu yokucindezela imibimbi inikeza impahla entsha.
