Mapangidwe Apamwamba Olondola Kwambiri Makina a CAM

Metallurgy ufa?

Powder metallurgy jakisonianabadwira ku California, USA mu 1973, wotchedwa MIM. Ndi mtundu watsopano wa luso zitsulo akamaumba anatulukira ndi kaphatikizidwe pulasitiki jekeseni akamaumba luso ndi munda wa ufa metallurgy.Powder zitsulo ndi pafupi ndi jekeseni akamaumba ndondomeko ndi ufa zitsulo luso, choyamba ufa olimba ndi organic binder kusanganikirana, kupyolera 150 madigiri kutentha Kutentha plasticizing, jekeseni nkhungu patsekeke ndi jekeseni akamaumba zida, kachiwiri ndi solidposition wa billet ntchito njira yotsiriza, ndiye decom kuchotsa billet ndi decom wotsiriza njira ya billet. monga zitsulo ufa, mwatsatanetsatane ndi sintering mbali.

Ufa zitsulo compaction akamaumba ndi ntchito ufa kudzaza nkhungu ndi mphamvu yokoka, kudzera makina kuthamanga extrusion akamaumba.Mu ntchito mafakitale othandiza ndi ambiri ankagwiritsa ntchito, ozizira chatsekedwa zitsulo kufa kukanikiza, ozizira isostatic kuthamanga, otentha isostatic kuthamanga, kutentha kuthamanga ndi kukanikiza akamaumba. Kugwiritsa ntchito ukadaulo wazitsulo zaufa kumalepheretsa kufunika kopanga zinthu zomwe zimachokera pochotsa zitsulo, potero kuchepetsa ndalama zopangira.

Monga otsogola opanga chigawo cha ufa, timapereka magiya azitsulo osiyanasiyana a ufa ndi sintered kuti agwiritse ntchito zingapo m'mafakitale angapo. Kupanga magiya achitsulo a sintered kumatha kubweretsa zovuta zambiri kwa opanga wamba. Ma geometries a giya ndi ovuta kwambiri, nthawi zambiri amafuna njira zachiwiri zowononga nthawi - kuwonjezera mtengo ku laimu wapansi. Ndi mdera lino pomwe zitsulo za ufa zimapambana.

Kupyolera mu kugwiritsira ntchito zida zolondola, kuthamanga kwa matani amphamvu, ndi sintering, magiya amatha kupangidwa ndi njira yachitsulo ya ufa (PM), kufupi ndi mawonekedwe a ukonde kapena mawonekedwe a ukonde, omwe amafunikira makina ochepa kapena opanda, komanso nthawi zozungulira mofulumira kwambiri kuposa makina.
Ubwino Wogwiritsa Ntchito PM muKupanga Zida
Kugwiritsa ntchito PM popanga zida kumapereka maubwino ambiri kuphatikiza kulolerana kolimba, magiya a PM opanda phokoso, komanso mphamvu zama voliyumu apamwamba. Phindu lalikulu logwiritsa ntchito chitsulo chaufa popanga zida ndizotsika mtengo. Kutha kupanga magiya ambiri ophatikizidwa ndi masinthidwe amkati ndi zigawo zolimba zololera kumachotsa kapena kuchepetsa kufunikira kwa ntchito zina. Zonse pamodzi zimabweretsa nthawi ndi ndalama zosungidwa pa ntchito yanu.

Popanda kutaya pang'ono, chitsulo cha ufa ndi njira yobiriwira chifukwa cha kuchepa kwa mphamvu yogwiritsira ntchito mphamvu ndi zochepa zochepa, zomwe zimapangitsa kuti zikhale zotsika mtengo kusiyana ndi kupanga makina kapena kuponyera. Kusankhidwa kwa zinthu zamagiya azitsulo zaufa kumathandizira kukhathamiritsa kwa magwiridwe antchito a gawolo kuti ligwiritsidwe ntchito ndikusintha pang'ono popanga.
