Izingxenye Zemoto Zenziwe ngokwezifiso abakhiqizi be-powder metallurgy

Incazelo emfushane:

Lokhu kuhlobene nomkhakha okhethekile we-powder metallurgy, njengoba ukuminyana, i-porosity, izinto zokwakha kanye nezindlela zokwelapha ukushisa kwamagiya e-powder metallurgy kuthinta ngokuqondile ubulukhuni namandla. impahla, ukuqina okuphezulu.Izindlela zokwelapha ukushisa ngokuvamile zihlanganisa ukucima i-carburizing, i-carbonitriding, i-high frequency quenching, i-low frequency quenching, ukucima uwoyela, njll.Inqubo yokucisha eqinile futhi efanelekayo igcina ubulukhuni bokwelashwa kokushisa buzinzile.


Imininingwane Yomkhiqizo

Amandla enkampani

Omaka bomkhiqizo

Izingxenye ZemotoNgenxa yokusebenza okusezingeni eliphezulu kanye nezindleko eziphansi zezinto ze-powder metallurgy, izingxenye ze-powder metallurgy zisetshenziswa kabanzi emotweni, okuhlanganisa izingxenye zokudonsa ukushaqeka, umhlahlandlela, i-piston kanye nesihlalo se-valve ephansi ku-chassis yemoto; Uhlelo lwamabhuleki lunenzwa ye-ABS, ibhuleki pad nokunye;Izingxenye zephampu ikakhulukazi ziyipompo likaphethiloli, iphampu kawoyela kanye nephampu yokudlulisela ezingxenyeni ezibalulekile;Injini inepayipi, iringi yesihlalo, induku yokuxhuma, isihlalo sokuthwala, izingxenye ezibalulekile zesistimu ye-variable valve timing (VVT) kanye ne-exhaust. ukwesekwa kwamapayipi, njll.Ukudlulisa kunehabhu ehambisanayo kanye nohlaka lwegiya leplanethi nezinye izingxenye.

I. Ukuthuthukiswa kwezingxenye ezizenzakalelayo ze-powder metallurgy

Ngokuthuthuka okusheshayo kwemboni yezimoto yaseShayina, imakethe yezingxenye zezimoto nayo igcine ukuthambekela okusheshayo.Ngo-2015, umkhiqizo wezimoto waseChina wafinyelela ezigidini ezingama-24.5033 zamayunithi, wakleliswa kuqala emhlabeni. inyuke cishe ngamaphesenti ayi-10 kusukela ngonyaka odlule. Ngakolunye uhlangothi, ngemva kokungena kweShayina enhlanganweni yezohwebo yomhlaba, akugcini nje ukwakha isethi ephelele yemboni yezimoto yangaphandle njengabasingathi, kanye nama-oda amakhulu asekhaya ezingxenye ze-powder metallurgy, umkhiqizo ngamunye, kanye nezinkampani zakwamanye amazwe ezisingatha imali ezweni lethu, ukwenza isethi ephelele yemikhiqizo ye-powder metallurgy ihlinzeka ngendawo yesidingo esikhulayo, isidingo sokunwetshwa ekuthuthukisweni kwamabhizinisi e-powder metallurgy eChina kulethe ithuba elingajwayelekile.

Ngokombono wenani eliphumayo lokuthengisa lezingxenye zezimoto ze-powder metallurgy, inani lokuthengiswayo likhuphuke lisuka ku-876.21 million yuan ngo-2006 laya kumayuan ayizigidi ezingu-367.826 ngo-2015, ngezinga lokukhula lonyaka elihlanganisiwe lika-17.28%, futhi lagcina umkhuba wokukhula ngokushesha okuqhubekayo. , kanye nesidingo semakethe yezingxenye ze-powder metallurgy sigcine inkambiso yokukhula ngokushesha.

Ukulawulwa kokuqina kwemikhiqizo ye-powder metallurgy ejwayelekile ngesikhathi sokwelashwa kokushisa

Ukuminyana kwempushana ye-athomu evamile (okuhlanganisa insimbi ye-carbon nensimbi ye-copper-carbon alloy) kungaphezu kuka-6.9, futhi ubulukhuni bokucisha bungalawuleka eduze kwe-HRC30.

Ngokuvamile, ukuminyana kwe-powder pre-alloyed (AB powder) kudlula i-6.95, futhi ubunzima bokucima bungalawulwa eduze kwe-HRC35.

Izimpushana eziphezulu ezifakwe ngaphambili ezinobuningi obukhulu kuno-6.95 kanye nobulukhuni bokucisha okulawulwa ku-HRC40.

Imikhiqizo ye-powder metallurgy eyenziwe ngezinto ezingenhla inokuqina okuzinzile kanye nezinto ezibonakalayo, futhi ubulukhuni ngemva kokwelashwa kokushisa buhlangabezana nezidingo ezihambisanayo, ngakho amandla abo okuqina namandla okucindezela azofinyelela esiqongweni esingcono.

Ingabe ubulukhuni bokwelashwa kokushisa kwe-powder metallurgy bufinyelela insimbi engu-45? Yebo ungakwazi!

Kodwa-ke, ngenxa yokuthi ukuminyana kwemikhiqizo ye-PM akuphakeme njengaleyo yensimbi enguNombolo 45, ukuminyana okuphezulu kakhulu kwezingxenye zokucindezela ze-PM kuvamise ukuba ngu-7.2 g/cm, kuyilapho ukuminyana kwensimbi engu-No. 45 kungu-7.9 g/cm.I-Carburizing ephoqelelwe i-powder metallurgy noma ukwelashwa kokushisa okuvama kakhulu okudlula i-HRC45 kuzokwenza imikhiqizo ye-powder metallurgy ibe brittle ngenxa yokucisha okukhulu, okuholela emandleni emikhiqizo ye-powder metallurgy.

Okulandelayo, sizoqhathanisa igiya lokwakha i-P/M negiya lokuhobha elinomshini.

1. Izinga eliphezulu lokusebenzisa impahla, kuze kufike ngaphezu kwama-95%

2. Cha noma ukusika kancane kuyadingeka

3. Ukungaguquguquki okuhle kwezingxenye, ukuzinza okuhle nokunemba okuphezulu.

4. Ukuqhathanisa amandla: abakhiqizi bensimbi abayizimpushana abachwepheshile bathuthukise ukwakheka kwesikhunta se-powder metallurgy, futhi amandla aqinile namandla acindezelayo egiya akhiqizwayo asondelene nalawo okubhoboza igiya.Isibonelo, igiya elishayelwa igiya lemoto elinokuhanjiswa okuphezulu. ukuqina futhi kuyigiya le-powder metallurgy.Igiya elibonakalayo, i-powder metallurgy liyasebenza futhi libanzi.

5. Ukucindezela i-Powder usebenzisa ukubunjwa kwesikhunta, kungakhiqiza obunye ubuchwepheshe bokusika be-hobbing abukwazi ukukhiqiza izimo eziyinkimbinkimbi.

6. Ngenxa yokuthi ifanele ukukhiqizwa ngobuningi, ukusebenza kahle kokukhiqiza kuphezulu futhi izindleko ziphansi kunokusika.

7. Ifanele ukukhiqizwa ngobuningi, ngakho intengo iyancintisana ngokuphelele.
