Iimpawu zemveliso

Amashishini anxulumene nesinyithi somgubo asebenza ikakhulu kushishino lweemoto, izixhobo zokuvelisa, ishishini lesinyithi, iarosfera, ishishini lezomkhosi, izixhobo, izixhobo zekhompyutha, izixhobo zombane zasekhaya kunye nezinye iinkalo zemveliso engenanto kunye nophando, izinto ezinxulumene noko ezingafunekiyo, imveliso yezinto ezincedisayo, zonke Iindidi zezixhobo zokulungiselela umgubo, izixhobo zokwenza izixhobo zokwenza izinto sintering.Iimveliso zibandakanya iibheringi, amagiya, izixhobo zokusika i-carbide, ukusweleka, iimveliso zokukhuhlana njalo njalo. kumashishini ezomkhosi, izixhobo ezinzima nezixhobo, ezinje ngeqokobhe lesikrweqe, i-torpedoes, iinqwelomoya kunye neetanki kunye Ezinye izibini eziqhekezayo kufuneka ziveliswe ngumgubo wentsimbi iteknoloji. Kwiminyaka yakutshanje, iindawo ze-P / M ziye zaba yeyona ntengiso inkulu kushishino lwe-P / M e China. Malunga neepesenti ezingama-50 zamalungu ezithuthi zizinto zeP / M.

(1) Izicelo: (iimoto, izithuthuthu, oomatshini bempahla eyolukiweyo, oomatshini bokuthunga amashishini, izixhobo zamandla, izixhobo zekhompyutha, izixhobo zombane, oomatshini bokwakha, njl.) Zonke iintlobo zomgubo wokunyibilikisa isinyithi (isiseko sobhedu).

(2) ucalulo: umgubo wokunyibilikisa isinyithi, izinto zokulwa ukungqubana, umgubo wokunyibilikisa isinyithi, izixhobo zomgubo wentsimbi, izinto ezenziwe ngomgubo wentsimbi, kunye nomgubo wokunyibilikisa isinyithi izinto zombane kunye nomgubo wokunyibilikisa isinyithi izinto zobushushu obuphezulu, njl.

Ukusuka kwimoto, iinxalenye zesithuthuthu kuwo onke amacandelo okunyibilikiswa kwesinyithi kubalwa inani lokunyuka.Uyabona ukuba.Impahla yokunyibilikisa isinyithi ikwindawo yophuhliso olukhawulezileyo kuwo onke amacandelo egolide emetallurgic metallurgical.If ngokweempawu Izahlulo zesahlulo. Ubungakanani bezinto ezakhiweyo kuwo onke amalungu asekwe ngentsimbi mkhulu kakhulu kunamanye amalungu.Ukuhluka kunye nemveliso yezixhobo zokunyibilikisa isinyithi ziyanda mihla le, kunye nobubanzi besicelo sazo Iya isanda ngokwanda.

Oku kungenxa ye: 1) xa izixhobo zinee-curve ezingaqhelekanga, i-eccentricity, i-radial protrusions okanye imingxunya: xa iigiya zinemingxunya engagunyaziswanga, iindlela eziphambili, amacala acabalele, i-splines, imingxunya yesikwere, imingxunya ye-taper; Xa igiya ine-protrusions, grooves, blind Imingxuma kunye nemingxunya yobunzulu obahlukeneyo kwicala le-axial. Iindlela zepowder zokunyibilikisa isinyithi kulula ukuzenza kwaye zifuna okanye zingaqhubekeki zenziwe ngomatshini. Ngokubanzi umgubo wokunyibilikisa isinyithi ngenkqubo yokwenza imveliso yokunyibilikisa umgubo, ifuna kuphela amanyathelo amahlanu. Ukwenza i-oyile yokuntywilisela Ukwenza ngomatshini kunye nokwenza izinto zokuphosa kunye nezinto zokwenza izinto. Emva kwemoto ngaphandle kwesangqa ngaphakathi kwesangqa isangqa esinye okanye ezimbini zobuso, indawo yokugaya erhabaxa, indlela ephambili, igiya yokuloba, ukuphazamisa, unyango lobushushu, ubushushu kunye ezinye iinkqubo ezilishumi, ke, xa kusetyenziswa umgubo wokunyibilikisa isinyithi ukwenza imveliso, ngenxa yephondo lezabasebenzi, imathiriyeli, imveliso ephezulu yokusebenza, ukusetyenziswa kwezixhobo ezincinci, ukonga umbane. Iindleko ze-ion zincitshiswe kakhulu. 2) xa usenza izixhobo ngomgubo wentsimbi.Umgangatho wokusetyenziswa kwezinto unokufikelela ngaphezulu kwe-95%. Kungenxa yokuba: Uhlobo lwe-A olunokuthi lwenziwe ngokuthe ngqo lube ngamalungu agqityiweyo: B. Nayo nayiphi na inkunkuma yokuxinana ngaphambi kokuntywila Ngaba ayinakucinywa iphinde isetyenziswe kwakhona? Oku akunakwenzeka xa iigesi zenziwe ngezinye iindlela zoomatshini. 3) Ukuzaliswa kwakhona komgubo wokunyibilikisa isinyithi kuhle kakhulu.Ngokuba umgubo; izixhobo zeTaijin zenziwa ngukuxinana komngxunya. Phantsi kweemeko zokusetyenziswa kwesiqhelo, isikhunta sinokucinezela amashumi amawaka ukuya kumakhulu amawaka ezixhobo zokwenza izixhobo

Okokuqala, izibonelelo zenkqubo yokunyibilikisa umgubo

1, inokuqhubekeka nezinto ezizodwa.Izinto ezenziwe ngomgubo wokunyibilikisa isinyithi zinokuvelisa isinyithi esinganyangekiyo kunye neekhompawundi, ii-alloys zobuxoki, kunye nezinto ezinokungena.

2, gcina isinyithi, unciphise iindleko.Ngokuba umgubo wentsimbi unokucinezelwa kubungakanani bokugqibela bokuxinana, akukho sidingo sokusetyenziswa kwemishini.Ukulahleka kwesinyithi okuveliswe ngale ndlela yiipesenti ezi-1 ukuya kwezi-5, xa kuthelekiswa neepesenti ezingama-80 inkqubo eqhelekileyo.

Ukuphuhliswa kweemveliso zetsimbi yokunyibilikisa isinyithi

1, umgangatho ophezulu wobume bezinto: umgubo wentsimbi ngummeli wentsimbi esekwe kwisinyithi, iya kuphuhliswa ibe ngumthamo omkhulu weemveliso ezichanekileyo, iinxalenye ezikumgangatho ophezulu.

2, ukusebenza kwe-alloy ephezulu: i-powder metallurgy yokuvelisa inesakhiwo esifanayo se-microstructure, ukucwangciswa kunzima kwaye kunzima kakhulu ukusebenza kwe-alloy.

I-3, isigaba esixubileyo esingumxube:

4.

5. Ukulungiselela izixhobo zokucoceka okuphezulu. Inkqubo yokunyibilikisa umgubo kwinkqubo yokuvelisa ayinyibiliki, ayizukudityaniswa nezinye izinto eziziswe kukungcola, kwaye ukuntywila kuqhutywa kwindawo yokucoca umoya kunye nokunciphisa umoya, ungoyiki igcwala kwaye Akuyi kubakho ungcoliseko lwezixhobo, ngoko ke, ukucoceka kwemveliso kuphezulu kakhulu.

6.Ukuchaneka kokuhanjiswa kwezinto. Indlela yokunyibilikisa isinyithi somgubo inokuqinisekisa ukuchaneka nokufana kobume bezinto ngokwenani.

7, imveliso ngobuninzi ukunciphisa iindleko.I-Powder metallurgy ilungele ukuveliswa kweemveliso ezinenani elikhulu leemilo ezifanayo, ezinje ngegiya kunye nezinye iimveliso ezinendleko eziphezulu, ezinokunciphisa kakhulu iindleko zemveliso.
