Zigawo Zomangamanga za Powder Metallurgy

Kufotokozera Kwachidule:

Izi zikugwirizana ndi munda wapadera wa zitsulo ufa, monga kachulukidwe, porosity, zipangizo ndi kutentha mankhwala njira ufa zitsulo magiya mwachindunji zimakhudza kuuma ndi mphamvu.High kachulukidwe amatanthauza zinthu aloyi ya kuuma mkulu, pores yaing'ono, kachulukidwe mkulu, zabwino. zakuthupi, high hardness.Kutentha njira mankhwala zambiri monga carburizing quenching, carbonitriding, mkulu pafupipafupi quenching, otsika pafupipafupi quenching, quenching mafuta, etc.Stable ndi oyenerera quenching ndondomeko kusunga kuuma kutentha kutentha khola.

Kachulukidwe wa ufa wamba wa atomized (kuphatikiza chitsulo cha carbon ndi copper-carbon alloy steel) uli pamwamba pa 6.9, ndipo kuuma kozimitsa kumatha kuwongoleredwa mozungulira HRC30.

Kawirikawiri, kuchuluka kwa ufa wa pre-alloyed (AB powder) kumaposa 6.95, ndipo kuuma kozimitsa kumatha kuwongoleredwa mozungulira HRC35.

Mafuta opangidwa ndi prealloyed apamwamba kwambiri kuposa 6.95 ndikuzimitsa kuuma komwe kumayendetsedwa pa HRC40.

Ufa zitsulo zopangidwa ndi zipangizo pamwamba ndi kachulukidwe khola ndi zakuthupi, ndi kuuma pambuyo kutentha mankhwala amakwaniritsa zofunika lolingana, kotero mphamvu zawo kumakanika ndi compressive mphamvu adzafika pachimake bwino.

Kodi kutentha mankhwala kuuma zitsulo ufa kufika 45 zitsulo? Inde mungathe!

Komabe, chifukwa kachulukidwe ka mankhwala a PM sipamwamba kwambiri kuposa chitsulo cha 45, chiwerengero chapamwamba kwambiri cha zigawo zosindikizira za PM nthawi zambiri zimakhala 7.2 g / cm, pamene chiwerengero cha chitsulo cha 45 ndi 7.9 g / cm. zitsulo za ufa kapena chithandizo cha kutentha kwafupipafupi choposa HRC45 chimapangitsa kuti zitsulo za ufa ziwonongeke chifukwa cha kuzimitsidwa kwakukulu, zomwe zimapangitsa mphamvu ya zitsulo za ufa.

Kenako, tifanizira zida zopangira P/M ndi zida zopangira makina.

1. Mlingo wapamwamba wogwiritsa ntchito zinthu, mpaka 95%

2. Ayi kapena kudula pang'ono kumafunika

3. Good dimensional kusasinthasintha kwa magawo, kukhazikika kwabwino komanso kulondola kwambiri.

4. Kuyerekeza kwamphamvu: akatswiri opanga zitsulo zopangira ufa akonza mapangidwe a nkhungu ya ufa, ndipo mphamvu yolimba komanso mphamvu yopondereza ya giya yopangidwa ili pafupi ndi zida zopangira zida. mphamvu ndi ufa zitsulo gear.Visible, ufa zitsulo giya ndi zothandiza ndi zambiri.

5. Ufa kukanikiza akamaumba ntchito nkhungu akamaumba, angatulutse ena kudula hobbing luso sangathe kubala akalumikidzidwa zovuta.

6. Chifukwa chakuti ndi yoyenera kupanga zambiri, kupanga bwino ndipamwamba ndipo mtengo wake ndi wotsika kuposa kudula.

7. Yoyenera kupanga misa, kotero mtengo ndi wopikisana kwambiri.
