Ukuze uthole ukuqonda okujulile kwekhasimende ngobuchwepheshe bethu bokubumba umjovo we-Metal, sizokhuluma ngokuhlukana ngayo yonke inqubo ye-MIM, ake siqale ohlelweni lokubumba namuhla.
Ubuchwepheshe bokwenza impushana kuyinkqubo yokugcwalisa i-powder exutshwe ngaphambili ibe yi-cavity eklanyelwe, ukusebenzisa ingcindezi ethile ngomshini wokunyathelisa ukuze wenze umkhiqizo wesimo esiklanyelwe, bese ususa umkhiqizo emgodini ngomshini.
Ukwakhiwa kuyinqubo eyisisekelo ye-powder metallurgy okubaluleka kwayo kungokwesibili ngemuva kokucwiliswa.Ikhawulela kakhulu futhi inquma yonke inqubo yokukhiqiza ye-powder metallurgy kunezinye izinqubo.
1. Ukuthi indlela yokwenza inengqondo noma cha inquma ngokuqondile ukuthi ingaqhubeka kahle yini.
2. Kuthinta izinqubo ezilandelayo (kuhlanganise nezinqubo ezisizayo) kanye nekhwalithi yomkhiqizo wokugcina.
3. Kuthinta ukukhiqiza okuzenzakalelayo, ukukhiqiza kanye nezindleko zokukhiqiza.
Ukwakha umshini wokunyathelisa
1. Kunezinhlobo ezimbili ze-die surface emshinini wokwakha:
a) Isikhunta esiphakathi nendawo siyantanta (iningi lenkampani yethu linalesi sakhiwo)
b) Indawo yesikhunta engashintshi
2. Kunezinhlobo ezimbili zezinhlobo zesikhunta ezintantayo endaweni yokunyathelisa:
a) Indawo yokudiliza ilungisiwe, futhi indawo yokubumba ingalungiswa
b) Isikhundla sokubumba silungisiwe, futhi indawo yokudiliza ingalungiswa
Ngokuvamile, uhlobo olumisiwe lwendawo ephakathi nendawo yokudayiza yamukelwa i-tonnage encane yokucindezela, futhi indawo ephakathi nendawo yokufa iyantanta ukuze kutholakale umthamo omkhulu wokucindezela.
Izinyathelo Ezintathu Zokubumba
1. Isiteji sokugcwalisa: kusukela ekupheleni kokudiliza kuze kube sekupheleni kwendawo yokubunjwa ephakathi ikhuphuka ifike endaweni ephakeme kakhulu, i-angle yokusebenza yomshini iqala kusuka ku-270 degrees kuya ku-360 degrees;
2. Isiteji sokucindezela: Yisiteji lapho impushana icindezelwa khona futhi yakhiwe emgodini.Ngokuvamile kukhona i-high die pressurization kanye ne-middle die surface eyehlayo (okungukuthi ukucindezela okuphansi) ukucindezela, ngezinye izikhathi kuba ne-pressurization yokugcina, okungukuthi, i-punch engenhla icindezela futhi ngemva kokuphela komshini, i-angle yokusebenza yomshini iqala kusukela kuma-degree angu-120. kuze kufike ku-180 degrees;
3. Isiteji sokubhidliza: Le nqubo inqubo lapho umkhiqizo ukhishwa emgodini wesikhunta.I-angle yokusebenza yomshini wokunyathelisa iqala kuma-degree angu-180 futhi iphetha ngo-270 degrees.
Ukusatshalaliswa kokuqina kwama-powder compact
1. Ukucindezelwa kwendlela eyodwa
Phakathi nenqubo yokucindezela, isikhunta sesifazane asinyakazi, i-punch ephansi yokufa (i-punch engaphezulu yokufa) ayinyakazi, futhi ukucindezela okucindezelayo kusetshenziswa kuphela emzimbeni wempushana ngokusebenzisa i-punch engaphezulu yokufa (i-low die punch).
a) Ukusatshalaliswa kokungalingani okujwayelekile;
b) Indawo ye-eksisi emaphakathi: isiphetho esingezansi se-compact;
c) Uma i-H, i-H/D ikhula, umehluko wokuminyana uyakhula;
d) Isakhiwo sesikhunta esilula kanye nokukhiqiza okuphezulu;
e) Ifanele izinto ezihlangene ezinobude obuncane nobukhulu bodonga olukhulu
2. Ukucindezela okubili
Phakathi nenqubo yokucindezela, isikhunta sesifazane asinyakazi, futhi ama-punches angaphezulu naphansi afaka ingcindezi ku-powder.
a) Ilingana nesikhundla esiphezulu sokucindezelwa okubili kwendlela eyodwa;
b) I-shaft engathathi hlangothi ayikho ekugcineni kwe-compact;
c)Ngaphansi kwezimo ezifanayo zokucindezela, umehluko wokuminyana mncane kunokucindezela okukodwa;
d) Ingasetshenziselwa ukucindezela ngamakhompiyutha amakhulu we-H/D
