Sintered Parts for Auto Components

Zigawo za sinteredndi mankhwala sintered amene amapangidwa kuchokera ufa ndi kulimbikitsidwa ndi sintering. Zigawo za Sintered nthawi zambiri zimadziwika ndi kulolerana kolimba komanso kumasuka kwa kukhazikitsa. Kusakaniza kwa ufa wakuthupi kumakhalanso ndi mafuta kuti muchepetse kukangana komwe kumachitika mukanikizira. Kusakaniza kwa ufa ndizinthu zoyamba zomwe zimagwiritsidwa ntchito popanga zigawo za sintered. Ufa woyambira ukhoza kukhala chitsulo choyera, chitsulo chochepa cha alloy, chitsulo chosapanga dzimbiri kapena chitsulo chothamanga kwambiri. Makhalidwe a gawo lomaliza amatha kusinthidwa pogwiritsa ntchito zowonjezera monga carbon, alloying elements ndi machinability enhancers. Zosakaniza za ufa zimakhalanso ndi zofukiza kuti zichepetse kukangana komwe kumachitika mukanikizira. Njira yodziwika kwambiri yosindikizira ndi kukanikiza kwa axial muzitsulo kapena carbide kufa. Makina osindikizira kapena makina osindikizira a hydraulic amatha kutulutsa zovuta za 400-800 MPa. Magawo owoneka movutikira amatha kukanikizidwa motsatira njira imodzi komanso zotulutsa zambiri mpaka magawo 25 pamphindi. Pambuyo kukanikiza, mbali mbamuikha kwa anakonzeratu mawonekedwe ndi kachulukidwe. Komabe, uku sikuli kukula komaliza kapena mphamvu.

Ubwino waPowder Metallurgy Njira

1. Zotsika mtengo
The mankhwala omaliza akhoza akaumbike ndi ufa zitsulo njira, ndipo palibe chifukwa kapena kufupikitsa processing wa makina .Ikhoza kupulumutsa zinthu kwambiri ndi kuchepetsa mtengo kupanga.

2. Mawonekedwe ovuta
Powder mtallurgy allows kupeza akalumikidzidwa zovuta mwachindunji compacting tooling, popanda Machining ntchito, monga mano, splines, mbiri, frontal geometries etc.

3. Zolondola kwambiri
Kuthekera kothekera kwa njira yophatikizira kumakhala π 8-9 monga sintered, kutheka mpaka T 5-7 mutapanga sizing.

4. Kudzipaka mafuta
The cholumikizira porosity wa zinthu akhoza fll ndi mafuta, kupeza ndiye kudziona koyenera kubala: mafuta amapereka mosalekeza. kondomu pakati pa kubala ndi kutsinde, ndipo dongosolo safuna mafuta ena owonjezera kunja.

5. Ukadaulo wobiriwira
Njira yopangira zinthu zopangira sintered imatsimikiziridwa kuti ndi zachilengedwe, chifukwa zinyalala zakuthupi ndizochepa kwambiri, zinthuzo zimatha kubwezeretsedwanso, komanso mphamvu zamagetsi ndizabwino chifukwa zinthuzo sizisungunuka.
