Investment casting, iyo inozivikanwa zvakare yakarasika wakisi kukanda kanaprecision casting, inoreva kuumbwa kweceramic kutenderedza mapatani ewakisi kuti igadzire yakawanda kana chikamu chimwe chete chekugashira simbi yakanyungudutswa. Maitirwo aya anoshandisa jekiseni rinoshanda rakaumbwa newakisi pateni kuita kuti riwane mafomu akaomarara ane hunhu hunoshamisa. Kugadzira mold, wakisi pateni, kana sumbu remapateni, inonyikwa mumidziyo yeceramic kakawanda kugadzira goko gobvu. De-wax process inoteverwa negoko rakaomarara. Iyo yakisi-isina Ceramic shell inobva yagadzirwa. Simbi yakanyungudutswa inobva yadirwa muceramic shell cavities kana cluster, uye kana yakasimba uye yatonhodzwa, ganda receramic rinodamburwa kuti riratidze chinhu chekupedzisira chakakandwa simbi. Precision yekudyara castings inogona kuwana yakasarudzika yechokwadi kune ese madiki uye makuru ekukanda zvikamu muakasiyana ezvigadzirwa.
Matanho e Investment Casting process:
Munguva yekudyara kwekudyara maitiro, wax pateni inoputirwa neceramic material, iyo, kana yakaomeswa, inotora iyo yemukati geometry yekukanda yaunoda. Kazhinji, zvikamu zvakawanda zvinokandwa pamwechete kuti zvinyatsoshanda nekuisa mapatani ewakisi ega pachimuti chepakati chinonzi sprue. Wakisi inonyungudutswa kubva patani - ndokusaka ichizivikanwawo senzira yakarasika wakisi - uye simbi yakanyungudutswa inodirwa mugomba. Kana simbi yasimba, mold yeceramic inozununguswa, ichisiya chimiro chiri padyo chekukandwa kwaunoda, kuchiteverwa nekupedzisa, kuyedza uye kurongedza.
Ndeipi iyo Investment Castings Inoshandiswa?
Investment castingsanoshandiswa zvakanyanya mumapombi nemavharuvhu, mota, marori, hydraulics, forklift marori uye mamwe akawanda maindasitiri. Nekuda kwekukandira kwavo kushivirira uye kupera kwakanaka, wakisi yakarasika inoshandiswa zvakanyanya uye zvakanyanya. Kunyanya, iyo Stainless simbi yekukandira mari inoita basa rakakosha mukuvaka ngarava uye mabhoti nekuti ane yakasimba anti-rust performance.
Pane zvikonzero zvakawanda zvokusarudzaRMC investment casting foundrysesosi yako yekudyara castings, izvi zvinosanganisira:
- Injiniya centric ine simbi yekukanda inotarisisa
-Kuwedzera ruzivo neakaomesesa geometri uye zvakaoma-ku-kugadzira zvikamu
- Huwandu hwakawanda hwezvinhu, zvinosanganisira ferrous uye kwete-ferrous alloys
- In-imba CNC machining kugona
-Kumwe-kumira mhinduro dzekudyara castings uye yechipiri maitiro
- Hunhu hunoenderana hunovimbiswa
-Kushandira pamwe kunosanganisira vagadziri vezvishandiso, mainjiniya, muvambi, machinist uye matekiniki ekugadzira.
Sezvo iyo mhangura-yakavakirwa alloys, ndarira nendarira zvinogona kuumbwa kuita zvikamu zvakaoma kwazvo, zvichiita kuti zvive zvakanakirainvestment casting process. Kuchinja-chinja kwemitengo nguva dzose kunogona kuita kuti zvinhu izvi zvive zvakanyanya kukoshesa mutengo, zvichiita kuti tsvina idhure zvakanyanya, kunyanya kana uchifunga CNC machining uye / kana kuforoma senzira yekugadzira kugadzira yako yekukanda zvikamu. Mhangura yakachena haiwanzokandwa. Investment (yakarasika wakisi) inzira yekukandira nemazvo padhuze-neti-shape details uchishandisa kudzokororwa kwewakisi. Investment casting kana kurasika wakisi isimbi yekugadzira nzira iyo inowanzo shandisa wakisi pateni yakakomberedzwa negoko receramic kugadzira mold yeceramic. Kana goko raoma, wakisi inonyunguduka, kuchisiya mold chete. Zvadaro chikamu chekukanda chinoumbwa nekudururira simbi yakanyungudutswa mumucheka weceramic.
Brass ialloy inoumbwa nemhangura uye zinc. Brass inoumbwa nemhangura uye zinc inonzi yakajairika brass. Kana iri mhando yealloys inoumbwa nezvinhu zvinopfuura zviviri, inonzi yakakosha brass. Brass isimbi yemhangura ine zingi sechinhu chikuru. Sezvo zinc yemukati inowedzera, simba uye plastiki yealloy inowedzera zvakanyanya, asi michina yemagetsi inoderera zvakanyanya mushure mekupfuura 47%, saka iyo zinc yendarira iri pasi pe47%. Kuwedzera kune zinc, ndarira yakakandwa kazhinji ine alloying zvinhu zvakaita sesilicon, manganese, aluminium, uye lead.
Brass yekukanda ine yakakwirira mechanical properties pane bronze, asi mutengo wakaderera pane bhuronzi. Cast brass inowanzo shandiswa kune chinangwa chakajairwa kutakura makwenzi, mabhuranzi, magiya uye zvimwe zvisingapfekeri zvikamu uye mavharuvhu uye zvimwe zvikamu zvinodzivirira kuora. Brass ine simba rekuramba kupfeka. Brass inowanzoshandiswa kugadzira mavharuvhu, pombi dzemvura, mapombi ekubatanidza emukati nekunze emhepo inofefetera, uye maraya.
