Ngatichekei neruzha. Kana vanhu vazhinji vakanzwa 'giravity die die casting parts', vanofananidzira mawidget asina chaanopomerwa, akakwira-vhoriyamu achikunguruka kubva pamutsetse. Ndiyo shanduro yebhurocha. Chokwadi chiri pauriri inhaurirano yenguva dzose pakati pechinangwa chekugadzira, hunhu hwesimbi, uye fizikisi yakasindimara yeforoma isingaperi. Hakusi kungodira simbi mugomba resimbi; iko kutonga kupisa, kutarisira kuderera munzvimbo dzisiridzo, uye kuziva kana dhizaini ichikumbira kukanganisa.
Nzvimbo Yepakati Isinganzwisisike
Gravity die casting inogara munzvimbo iyi inonakidza, inowanzosashandiswa zvisizvo pakati pekukanda jecha nekukanda kwepamusoro-soro kufa. Ini ndinoona ma specs achiuya nguva dzese apo mumwe munhu anoda kugadzikana kwedimensional uye kupedzisa kwakanaka kwechigarire mold, asi nekuoma kwemukati kwekukandira jecha. Hazvishande zvakadaro. Simbi inoda nzira yekuyerera nekudyisa. Iwe haugone kuve wakasarudzika zvikamu zvinorema kuseri kwemadziro matete-ndiyo shrinkage gomba rakamirira kuitika. Iyo mold, kuva simbi isingachinjiki, hairegereri.
Takadzidza izvi nenzira yakaoma makore kumashure pane bracket ye hydraulic manifold. Dhirowa yemutengi yaive yakanaka, yakabatana dhizaini ine bhegi gobvu rinosimudzwa riri padhuze nekutetepa flange. Zvinotaridzika zvakanaka paCAD. Muchokwadi, bhegi racho rakasimba rekupedzisira, richisveta simbi kubva kune yakatosimba-yakasimba chikamu chakaonda, ichisiya porous, isina kusimba junction. Kugadzirisa kwanga kusiri kungogadzirisa kudira; zvaireva kudzokera kumugadziri uye kuwedzera mbabvu yakavanzika kuti iite senzira yekudyisa. Ndiro zuva nezuva: chikamu engineering.
Apa ndipo panowanikwa chiitiko chemugadziri ane maitiro akasiyana anobhadhara. Kambani yakadai Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), nekwavanobva mugoko uye kuisa mari, vane gumbo kumusoro uku. Vanonzwisisa maitiro ekusimbisa kubva kune yakaoma castings. Kushandisa ruzivo irworwo kusimba rinokwevera zvinhu pasi zvinoreva kuti havangori vazadziri; vari kufunga nezvekuti simbi inofamba sei nekutonhorwa kubva pakuenda. Iwe unogona kuona maitiro avo pane yavo portal pa tsngtaocnc.com- ndeye maitiro akakodzera echikamu, kwete kungotengesa chete kugona.
Nyaya Haisi Yokungofunga
Aluminium inowana kubwinya kwese, asi mutambo unochinja zvachose nemamwe maalloys. Tiri kutaura giravhiti kufa kukanda zvikamu mundarira, kana kunyange mamwe magnesium alloys. Mumwe nemumwe ane drama rake. Aluminium A356? Iwe uri kutonga strontium shanduko ye eutectic silicon uye kubata nehydrogen pickup. Dururira zvakanyanya, uye unobika mu porosity simbi isati yatanga kutonhora.
Asi taura kuti unoda chikamu mune nickel-based alloy ye-high-temp service. Kamwe kamwe, kuneta kwekupisa paH13 simbi mold inova nzira yakaoma. Iko kupisa kwemhepo kubva pakudurura pa1500 ° C+ maringe nealuminium pa700 ° C kune hutsinye. Upenyu hweMold hunoderera. Mari yako modhi inobuda nepahwindo. Apa ndipo panotaurwa QSY yekushanda nema alloys akakosha senge nickel-based haingori bullet point. Zvinoreva kuti vakafanirwa kugadzirisa idzi nyaya dzekudziya dzekudziya, pamwe kuburikidza neakasarudzika mold coatings kana akadzora kutonhora chiteshi nzira. Irigi rakasiyana nekuburitsa maaluminium housings.
Ini ndinorangarira purojekiti yeimba ye sensor mu duplex simbi isina tsvina. Iyo corrosion specs yaive yakasimba. Iyo gravity die process yakatipa kupedzisa kwepamusoro uye kuenderana kunodiwa, asi kudzora chiyero cheferrite-austenite kuburikidza nekutonhodzwa kunodzorwa kwekuumbwa kwechigarire kwaive kutyisa. Isu takapfuura gumi nemaviri emafuta ekutenderera profiles pane mold tisati tawana inowirirana microstructure. Chaive chiyeuchidzo chekuti 'kufa' mukukanda kwesimba rinokwevera zvinhu kwakangofanana nechishandiso chekugadzirisa kupisa sechombo chekuumba.
The Machining Handshake
Uku ndiko kugadzira-kana-kupwanya kunoitwa nevazhinji pure-play foundries. A gravity die cast chikamu hachiwanzo magumo-chigadzirwa. Iyo iri padyo-net-shape isina chinhu yakananga kune CNC vise. Kana iyo yekutanga isinganzwisisi machining, iwe unowana marudzi maviri emusoro: zvisingaenderane datum nzvimbo dzinokanganisa gadziriso, kana dzakavanzwa dzakaoma nzvimbo kubva mukutonhora kusina kuenzana kunopwanya maturusi.
Kubatana kwakakosha. Kana imba yekukandira ichimhanyawo CNC mitsetse, sezvinoita QSY, pane mhinduro loop. Iyo machinist inoudza muvambi kuti yega yega yechitatu kukanda ine nzvimbo yakaoma pane chaiyo flange. Iyo yekutanga inotarisa kutonhora kwekuumbwa uye inoona imwe tambo yemvura yakavharwa zvishoma, ichigadzira nzvimbo inopisa yemuno uye yakachinjika microstructure. Dambudziko rakagadziriswa panzvimbo. Pasina iyo yekubatanidza, imhosva mutambo pakati pemupi nemuchina shopu.
Isu tinosimbirira pakuongorora kwekutanga-chinyorwa kunosanganisira kuyedza machining. Kanda batch, dhonza sampuli, woiisa paguyo. Inogadzirisa zvakachena here? Inogadzira muchina here? Iyo dimensional report kubva kuCMM chinhu chimwe chete, asi ruzha rweanocheka uye ruvara rwechipi rwunotaura nyaya chaiyo. A good gravity die casting haangosangana neprint tolerances; inoita sechinhu chinofanotaurwa.
Kana Zvikashata (Uye Zvichadaro)
Kutadza kuongorora ndiko kwaunonyatso dzidza. Ndakaona zvikamu zvichipfuura X-ray uye dhayi inopinda, zvobva zvatadza mukuneta kuyedzwa. Kutsemuka nguva dzose kunotanga panzvimbo yaitaridzika yakachena. Kazhinji, haisi hurema hwakakomba, asi yakavanzika oxide fold kana micro-shrinkage cluster yakagadzirwa panguva yekuzadza. Nekudururira simba regiravhiti, kana geji risina kunaka kugadzira laminar kuyerera, unopeta muganda reoxide kubva pamusoro perukova rwakanyungudutswa. Iyo inova yakakwana crack initiator yakavigwa mukati memadziro.
Imwe classic ndeye kukanganisa. Iwe unodhonza chikamu kubva mukuumbwa, inotarisa paCMM. Mushure mekupisa kurapwa (T6 yealuminium, toti), inoputika. Izvo zvakasara zvinosimbisa kubva mukutonhodza zvisina kuenzana muuyo wakaoma zvinoburitswa. Iye zvino wakamira nekuedza kutwasanudza chikamu chinopisa, inova nzira huru yekuunza kushushikana kutsva. Mhinduro yacho inowanzo mukugadzira mold - symmetrical kutonhora, dzimwe nguva kunyange nzvimbo dzakarongwa dzekuisa kuenzanisa kumberi kwekusimbisa.
Aya haasi matambudziko edzidziso. Ndiwo maawa anopedzwa pakuzunza, kukwenya musoro wako, kuchinjanisa thermocouples, uye kugadzira mabheseni ekudira. Chinangwa inzira yakasimba, kwete muenzaniso wakanaka. Kukosha chaiko kwemutengesi kuri mumabatiro avanoita izvi zvisingadzivisiki glitches. Ivo vane metallurgical uye kudzika kwemaitiro ekuongorora nekugadzirisa, kana vanongokanda rimwe batch uye tariro?
The Realistic Application Inotapira Spot
Saka giravhiti rinofa kukanda kupenyera papi? Izvo zvezvikamu zvinoda zvirinani zvemuchina uye kupera kwepasi pane kukanda jecha, mumavhoriyamu asingakodzeri mutengo wakakura wekushandisa wekukanda-kumanikidza kufa. Funga misoro yemasilinda, mabhuraketi ezvimiro zveaerospace kana auto, pombi dzimba dzinokosha zvemukati wepamusoro. Zvikamu zvaungaite 80% yenzvimbo, saka iwe unoda kufanofungidzira, dense substrate.
Ndiko zvakare kune makuru, anorema makanda. High-pressure ine miganho yekupfura saizi. Ndakaona zvakanakisa giravhiti kufa kukanda zvikamu kumichina yemaindasitiri inorema kupfuura 50 kg. Iwe hausi kuita izvo muchina wekamuri inotonhora. Maitiro acho anochinjika uye ekushandisa, nepo isiri yakachipa, maodha ehukuru hwakaderera pane yakanyanya-kudzvinyirira kufa seti.
Kutarisa pane portfolio yakaita seQSY's, iyo inotangira kubva kune yakaoma yekudyara castings kuenda kumachina, zvine musoro. Gravity die casting inokodzera munharaunda iyoyo yepakati kune zvikamu zvakaomesesa uye zvinoda kunotevera kunyatsoita machining. Inyanzvi, kwete yezvigadzirwa, maitiro. Mhedzisiro, kana yaitwa neiyo nhanho yekutarisa kwakabatanidzwa, haingori chikamu. Iyo yakasimbiswa pre-yakagadzirwa isina chinhu inoita kuti mugadziri arare husiku. Ndiko kubuda chaiko, kupfuura kungozvikanda chaiko.
