Isitofu sesinyithi sokubumba⎮Umgubo weMetallurgy⎮Ngathi

• Ukwenziwa komgubo linqanaba lesibini lomgubo wesinyithi. Yinkqubo apho i-powder ekhululekile yenziwe kwiibhilithi ezinobumba obuthile, ubukhulu, ubuninzi kunye namandla.

• Yenza umgubo ngenkqubo yokubumba ukuze ufumane ubume obunikiweyo kunye namandla omzimba womgubo, obizwa ngokuba yi-compact.

Zininzi iindlela zokwenza umgubo, ukongeza kwindlela eqhelekileyo yokubumba, ezinye zihlelwa njengeendlela ezikhethekileyo zokubumba. Ukwenziwa kweDie yeyona ndlela isisiseko.

ukuswela ukwenziwa koshicilelo - ukuphosa i-pulp - i-sintering ekhululekile

Ezi nkqubo zilandelayo zisetyenziselwa ukubumba izinto: uxinzelelo, ukufa, kushushu, isostatic, ukuqengqeleka, i-centrifugal, i-extrusion, kunye nokuqhuma.

• Ubuchule bokubumba obukhethekileyo;

• ukubumba okuqhelekileyo;

• ukunyangwa komgubo;

•ithiyori yocinezelo

Ukunyangwa kwangaphambili komgubo kubandakanya ukuthambisa, ukujongwa, ukuxutywa, ukugranula, kunye nokongeza izithambiso, phakathi kwezinye izinto.

Ukwenziwa komgubo wesiqhelo

Ukwenziwa komgubo yeyona ndlela isetyenziswa kakhulu yokwenza umgubo. Ibhekisela kwindlela yokulayisha i-powder edibeneyo ngokulinganayo kwi-mold evaliweyo kwisixa esithile kwiqondo lokushisa, kwaye emva koko uyicinezele kwi-billet kunye noxinzelelo lweyunithi ethile ngokushicilela.

Le nkqubo yokwenza ngokuqhelekileyo iquka la manyathelo alandelayo: ukulinganisa umgubo, umgubo wokuzalisa, ucinezele, ubambe uxinzelelo kunye nokuhlutha.

Umgaqo wokubumba

(1) Sebenzisa isixokelelwano ukunika umgubo uhlobo olufunekayo.

(2) Ukubonelela umzimba ngokobungakanani bawo obuchanekileyo.

(3) Cacisa i-billet eyimfuneko kunye nohlobo lwe-porosity.

(4) Ukubonelela umzimba ngomlinganiselo ofanelekileyo wamandla kunye noxinaniso lokuphatha.

Indlela yokucofa

Ukucinezela unidirectional: i-concave iyafa kwaye i-punch ephantsi ayishukumi, kwaye i-punch ephezulu igxininiswe ngokungaqhelekanga.

Indlela ezimbini ngaphambilissing: i-concave die igxininiswe, kwaye i-punch ephezulu nesezantsi icinezelwe ngexesha elifanayo kunye noxinzelelo olulinganayo kunye noluchaseneyo.

Ukucinezela okudadayo: i-punch esezantsi ilungisiwe, i-concI-ave die ixhaswa yimithombo, iisilinda, iisilinda, njl., kwaye inokudada emva koxinzelelo.

Inkqubo yokucofa

Inkqubo yokucinezela inokwahlulwa ngokwezigaba ezine:

(1) Amasuntswana omgubo ayashukuma, imingxunya iyancipha, kwaye amasuntswana acudisana;

(2) I-powder igxininiswe ngokuqinileyo, kwaye iincinci ezincinci zizaliswe kwi-gap phakathi kweengqungquthela ezinkulu, kwaye iinqununu ziqala ukuguquka;

(3) Inxalenye ye-concave kunye ne-convex yomphezulu we-powder particle icinezelwe kwaye ifakwe kwisimo soqhagamshelwano oluqinileyo;

(4) Umsebenzi wokuqiniswa kweengqungquthela zepowder ukuya kumda womda, ukwandisa ngakumbi uxinzelelo, iinqununu zepowder ziyatshatyalaliswa kwaye i-crystallization ihlanjululwe.

Ubudlelwane phakathi kokuqina komgubo wesinyithi kunye noxinzelelo loxinzelelo

Isiphumo sokucoceka komgubo

Ngenxa yenkqubo eyahlukileyo yokwenza umgubo, ukucoceka kwepowder akufani, kwaye ipowder iqulethe inani elithile lokungcola. Ukungcola kwipowder kuninzi kwimo ye-oxide yensimbi.

I-metal oxide powder ininzi ilukhuni kwaye i-brittle, kwaye isasazwa kakhulu kumphezulu we-metal powder, okwandisa ukunyanzeliswa koxinzelelo kunye nokuphazamisa ukusebenza koxinzelelo.

Ukwenziwa komgubo wesakhiwo samalungu

1. Ukwenza ukubumba kunye nokudibanisa kube lula, zama ukukhetha i-straight, i-symmetrical design ethintela ukuhluka okugqithisileyo kwicandelo kunye ne-grooving emxinwa, indawo engqukuva, njl.

2. Gwema iindonga ezinqabileyo zendawo ukuququzelela i-powder compaction kunye nokuthintela ukuqhekeka.

3. Gwema i-grooves kunye nemingxuma kwiindonga zecala ukuze kube lula ukuxinzelela okanye ukunciphisa iibhloko eziseleyo.

4. Gwema ukwandisa indawo ye-cross-sectional ecaleni kwendlela yokucinezela ukuququzelela ukuxinana. Iikona kufuneka zijikelezwe ekudibaneni kodonga ngalunye ukuququzelela ukuxinwa kunye nokuphepha ukuxinzelela uxinzelelo.

Umgubo wokubumba icandelo

Uhlobo lokuqala lwamalungu: ukucinezela unidirectional, udonga olubhityileyo, imilo engafanelekanga, inxalenye yetafile (ubukhulu bodonga ngokuqhelekileyo ukuya kuthi ga kwi-6.35mm)

Uhlobo lwesibini lwenxalenye: inxalenye yetafile, nayiphi na ubude kunye nokumila, kufuneka ibe ngamalungu acinezelayo.

Icandelo III: Inxalenye yeetheyibhile ezimbini, zabo nakuphi na ukuphakama nokumila, ekufuneka zicinezelwe macala omabini

Uhlobo lwesine lwamalungu: iitafile ezininzi, nakuphi na ukuphakama kunye nokumila, kufuneka kusetyenziswe iindawo ezininzi ezicinezelayo ezicinezelayo.
