Dahaarka laysarka: farsamo dib-u-cusboonaysiin cagaaran oo "hubka sare" ku durta matoorada dhuxusha

Hoosta qoto dheer ee macdanta dhuxusha, tiirarka taageerada haydarooliga ee nidaamyada macdanta ee si buuxda loo farsameeyay ayaa ku qulqulaya cadaadis 10,000-tan ah, weelasha gudbiyaha xoqa ayaa ka shiidaya dhuxusha, halka dhululubada haydarooliga ay ku dhibtoonayaan inay ka shaqeeyaan jawi qoyan oo daxal leh. Qaybahan muhiimka ah waxay sameeyaan "qaab-dhismeedka birta" ee hawlaha macdanta dhuxusha, iyagoo waara xirashada aan kala go 'lahayn, daxalka, iyo saameynta muddo dheer. Hababka dayactirka dhaqameed sida alxanka dusha sare, dahaarka chromium, ama beddelka dhammaystiran ma aha oo kaliya inay qaali yihiin oo waqti badan qaataan laakiin sidoo kale waxay ku guuldareystaan ​​​​inay daboolaan baahida macdan qodista dhuxusha casriga ah ee hawlgallada hufan, kaarboon yar, iyo kharash-ool ah. Soo bixitaanka tignoolajiyada dahaarka laysarka ayaa hadda keenaysa "kacaan dib-u-cusboonaysiinta birta" oo deggan warshadaha mishiinnada dhuxusha.

I. Dahaarka laysarka: "qalliin sax ah" oo lagu sameeyo dib-u-soo-saarka mashiinka dhuxusha

Dahaarka laysarka ma aha "filim" dusha sare ah oo fudud, laakiin waa tiknoolajiyad casri ah oo samaysa barkad dhalaal yar oo dusha sare ee qaybta oo leh laambad laysar oo tamar sare leh isla markaana isla mar ahaantaas buufinaysa budada dahaarka gaarka ah si loo gaaro isku xidhka birta ee u dhexeeya lakabka dahaarka iyo salka. Qiimaha asaasiga ah wuxuu ku jiraa:

Dayactirka bartilmaameedka saxda ah: Laydhka laysarka waxaa si sax ah loogu meeleyn karaa inuu xidho godad iyo godad daxal leh, iyadoo laga fogaanayo waxyeelada soo gaarta substrate-ka caafimaadka qaba, gaar ahaan ku habboon hagaajinta cilladaha maxalliga ah sida xoqidda tiirarka haydarooliga iyo xoqidda derbiga gudaha ee dhululubada.

Xidhmo adag oo bir ah oo adag: Lakabka dahaarka iyo matrix-ku waxay sameeyaan isku-darka faafinta atomiga, xoogga isku-xidhka waa ilaa 400MPa, si buuxda ayay u baabi'inaysaa khatarta ah in dahaarka chromium uu diirmo.

Waxqabadka la habeeyey: Marka la doorto daawaha ku salaysan kobalt-ka ee u adkaysta xirashada (sida Stellite 6), daawaha ku salaysan nikkel-ka ee u adkaysta daxalka ama isku-darka carbide-ka ee tungsten-ka ee la xoojiyay, awoodda badbaadada ee qaybaha xaaladaha shaqada ee adag sida saameynta dhuxusha ee gangue iyo daxalka uumiga biyaha aashitada ayaa la hagaajin karaa.

II. Adeegsiga wax ku oolka ah: Laga bilaabo "xoqidda geeska" ilaa "waxqabadka ka sarreeya"

1. Taageerada Haydarooliga "kacaanka fidinta nolosha"

Ka dib marka lakabka dahaadhka chromium ee dusha sare ee tiirka haydarooliga laga furo, tiirka si fudud ayuu u miridhku u dhici karaa oo wuu ku dhici karaa cadaadis sare. Tiknoolajiyada dahaarka laysarka waxay:

Ka dib marka laga saaro dahaarka duugga ah, lakab daawaha ah oo ku salaysan kobalt oo dhumucdiisu tahay 0.8-1.5mm ayaa si toos ah loogu shubaa dusha sare ee substrate-ka;

Adkaanta ayaa la kordhiyaa ilaa HRC 55-60 (lakabka dahaadhka chromium ee asalka ah waa HRC 40-45 oo keliya), iska caabbinta xirashadana waxaa kordha in ka badan 3 jeer;

Iska caabbinta daxalka ayaa si weyn loo xoojiyay. Cimriga adeegga ee tiirka dayactirka macdanta ee biyaha macdanta aashitada ah wuxuu gaaraa 18 bilood, taasoo aad uga badan qaybta cusub ee asalka ah (6-8 bilood).

2. Godka dhexe ee mashiinka xoqidda ayaa "dib loo hindisay"

Xirashada sanadlaha ah ee saxanka hoose ee godka dhexe waxay gaartaa ilaa 15mm, iyadoo beddelka dhaqameedku uu ku kacayo in ka badan 20,000 yuan halkii unug. Xalka dahaarka laysarka wuxuu mariyaa walxaha isku-dhafka birta ah ee tungsten carbide ee lagu xoojiyay qaybaha xirashada ee derbiyada godka. Iyada oo la gaarayo adkaanta dusha sare ee ka sarreysa HRC 62, hal-abuurkani wuxuu kor u qaadaa iska caabbinta xirashada 5-8 jeer. Codsiyada goobta ee meelaha macdanta laga qodo waxay muujinayaan in godka dhexe ee la soo celiyay uu dheereeyo cimriga adeegga laga bilaabo 6 bilood ilaa 24 bilood, halka kharashyada dayactirka halkii tan ee dhuxusha ay hoos u dhacaan 40%.

3. "Dib-u-dhiska" derbiga gudaha ee dhululubada haydarooliga

Si wax looga qabto cilladda shaabadeynta oo ay keento xoqidda derbiga dhululubada: Nidaamku wuxuu adeegsadaa quudinta budada coaxial oo ay weheliso tuubo laysar ah oo loogu talagalay godadka gudaha, taasoo suurtogalinaysa alxanka saxda ah ee meelaha xaddidan. Qalafsanaanta dusha sare ee dayactirka ka dib (Ra ≤ 0.8μm) waxay ka sarreysaa heerarka cusub ee mashiinnada qaybaha. Tijaabooyinka goobta ee warshadda mishiinnada dhuxusha waxay muujinayaan in dhululubada la dayactiray ay gaaraan 100% u hoggaansanaanta waxqabadka shaabadeynta halka ay ku kacayso oo keliya 30% wax soo saarka dhululubada cusub.

III. Isbeddel Saddex-geesood ah: Dhaqaalaha, Hufnaanta iyo Isbeddelka Cagaaran

IV. Laga bilaabo dayactirka ilaa casriyeynta: mustaqbalka dib-u-soo-saarka caqliga leh ee matoorada dhuxusha

Iyada oo la isku darayo teknoolojiyada caqliga badan, dahaarka laysarka ayaa gaaraya heer cusub oo ku saabsan codsiyada mishiinnada dhuxusha: 1) Goobaha shaqada ee robotic-ga ee otomaatiga ah waxay awood u siinayaan dayactirka heerka dufcadda ee qaybaha sida tiirarka iyo dhululubada, taasoo kor u qaadaysa hufnaanta 50%; 2) Kormeerayaasha dayactirka saadaalinta mataanaha ah ee dhijitaalka ah waxay kormeeraan xirashada qalabka dareemayaasha si ay si firfircoon u sameeyaan dayactirka dahaarka ka hor inta aysan dhicin cillado; 3) Alaabada shaqada ee Gradient waxay horumariyaan lakabyo dahaar isku dhafan oo leh dusha sare ee dibadda ee aadka u adag si ay u iska caabiyaan xirashada iyo lakab gudaha ah oo xooggan oo u adkaysta dildilaaca, si wax ku ool ah wax uga qabashada xaaladaha hawlgalka ee isku xiran ee xirashada saameynta.
