China Powder zitsulo zida kupanga

Powder metallurgy zida

Magiya ndi gawo lofunikira kwambiri pakutumiza kwamanja. Nthawi zambiri, magiya amakumana ndi kupsinjika kwakanthawi panthawi ya meshing, ndi nsonga zopanikizika zomwe zili pafupi ndi giya. Chifukwa chake, magiya amafunikira mphamvu zambiri komanso kukana kuvala kwambiri pamtunda kapena pafupi ndi pamwamba. Zolakwika za geometry ya zida kapena zida zimatha kuchepetsa moyo wamagiya ndi kuchuluka kwa katundu, ndikuwonjezera phokoso. Chifukwa chake, zofunikira zamagiya opatsirana nthawi zambiri zimakhala zapamwamba kwambiri, nthawi zambiri zimakhala zokwera kuposa DIN7. Kuphatikiza pa zofunikira za mphamvu ndi phokoso, zofunikira zowonjezera chuma ndi ntchito zimawonjezeredwa. Zonyamula magiya zimakhala zopanikizika kwambiri pamtunda kapena pafupi, kotero kuti kachulukidwe wathunthu wa gawo lonse sikufunika. Kusankha kwapamtunda ndikoyenera kutengera izi, njirayo imatha kupanga wosanjikiza pamwamba pa gawolo, porosity yamtunda ili pafupi ndi ziro, ndipo porosity yapakati nthawi zambiri imakhala pafupifupi 10%. M'zaka zaposachedwa, PMG yapanga njira ya DensiForm, yomwe imangowonjezera kachulukidwe ka pamwamba pa giya yotenthedwa ndikusungabe porosity ya pachimake, zomwe zimapangitsa kuti pakhale mawonekedwe owundana kwambiri mpaka kuya kwa 0.5-1mm. Wopangidwa ndi njira ya zitsulo za ufa, magwiridwe antchito amagwiritsiridwa ntchito mokwanira pakutumiza komweko.

Zigawo za gawo kufala kalunzanitsidwe buku ndi zinthu chitukuko chaufa zitsulo zigawomakampani. M'zaka zingapo zikubwerazi, mbali izi zithandizira kuti kukula mofulumira kwa mafakitale ufa zitsulo. M'zaka zaposachedwapa, zonse ndi pamwamba zimatha ufa zitsulo zitsulo ndi zipangizo zinchito akhala bwino. , kupita patsogolo kumeneku kumatheka pogwiritsa ntchito zipangizo zamakono zopangira ndi njira, monga ng'anjo zomwe zingathe kusungunuka Cr-alloyed steel kapena DensiForm's selective densification process. Kuvomerezedwa kwatsopanoufa zitsulo zigawo zikuluzikulu, kuphatikiza manja otsetsereka ndi zida zonyamula katundu, zimatsegula msika wazogwiritsa ntchito njira zatsopano zopangira zitsulo za ufa potumiza.
