Yiziphi izici ezithinta ikhwalithi ye-powder metallurgy pressing yezingxenye zemoto?

Amaphesenti angamashumi ayisishiyagalolunye ezingxenye ezinembile zezimoto akhiqizwa yi-powder metallurgy.Inqubo ye-powder metallurgy ihlanganisa ubuchwepheshe bokwenza i-PM press kanye nobuchwepheshe bokubumba umjovo we-MIM.Amagiya ezimoto, ama-bearings ezimoto, izingxenye ze-automotive tailgate, kanye ne-automotive wiper parts acindezelwa ukukhiqizwa kobuchwepheshe be-PM Forming.

I-Factor Ⅰ: umthelela wesikhunta esakha umshini

Ukubaluleka kwesikhunta kubuchwepheshe bokwenza amaphephandaba kuyabonakala.Kunconywa ukusebenzisa isikhunta sesifazane noma i-mandrel eyenziwe nge-carbide enosimende, insimbi eyimpuphu enesivinini esikhulu nezinye izinto.Isikhunta sisebenza kanye nobukhulu obungaphezulu buncane ngangokunokwenzeka ukuze kuncishiswe izinhlayiya zempushana kanye nesikhunta Isici sokungqubuzana phakathi kwezindonga.

I-Factor Ⅱ: umthelela wezigcobo

Ukwengeza i-lubricant ku-metal powder exutshwe kunganciphisa ngempumelelo ukungqubuzana phakathi kwe-powder naphakathi kwe-powder nodonga lwesikhunta, futhi kwenze ukusatshalaliswa kokuqina kwe-compact ngaphezulu komfaniswano.I-lubricant esetshenziswa kakhulu i-zinc fatty acid.Nakuba ingathuthukisa izimo zokunyathelisa, ngenxa yobuningi bayo obuncane, ukuhlukaniswa kulula ukwenzeka ngemva kokuxubana, futhi izingxenye ze-sintered zivame ukugoba nezinye izinkinga.

Isici Ⅲ: Umthelela wamapharamitha wokucindezela

1: Isivinini esicindezelayo

Uma isivinini sokucindezela sishesha kakhulu, sizothinta ukufana kwe-green compact density futhi kuzophinde kubangele imifantu.Kungcono ukusebenzisa umshini we-hydraulic powder forming machine ukuze uyikhiqize.

2: Ukubamba isikhathi sokucindezela

Ngaphansi kokucindezela okukhulu kakhulu nokubamba ingcindezi isikhathi esifanele, ukuminyana okuhlangene kokucindezela kwe-powder metallurgy kwezingxenye zemoto kungandiswa kakhulu.

3: Isakhiwo samabhuzu okuphakela impushana

Uma isicathulo sokudla i-powder jikelele sisetshenziselwa ukugcwaliswa kwe-powder, ukugcwaliswa kwe-powder okungalingani kuzokwenzeka phezulu naphansi noma ngaphambi nangemva komgodi, okuzothinta ikhwalithi ye-compact.Ukuthuthukisa noma ukuhlela kabusha isicathulo sokudla i-powder kungathuthukisa ukufana kokugcwalisa i-powder.
