Paunoona 'Precision Casting Pvt Ltd' muzita rekambani, zviri nyore kuita fungidziro. Vazhinji vanobva vangofunga nezvekushivirira kwepamusoro, zvikamu zvakaoma kunzwisisa, kazhinji vachizvibatanidza chete nekuisa mari. Izvo hazvina kuipa, asi hazvina kukwana. Iyo 'Pvt Ltd' chimiro chakajairika munzvimbo dzakawanda dzekutsvaga, asi hapana chainokuudza nezve hudzamu hwekugona. Ndakaona zvitoro zvine zita irori zvichimhanya makumi emakore-ekare girinhi jecha mitsetse yekukandwa kwakashata, uye mamwe anoshanda-ye-the-art vacuum induction induction kunyunguduka uye shell molding masisitimu emidziyo yemuchadenga. Kiyi haisi musoro; ndiyo nzira yekugona shure kwayo. Kusanzwisisika uku ndiko uko kutsvaga kunowanzo kugumburwa-kufunga kuti chokwadi chinopihwa kwete mhedzisiro yakasimbiswa yemaitiro chaiwo uye zvidzoro.
Iyo Core: Zviri Zvekuita, Kwete Kungovimbisa
Kukandira kwechokwadi chaiko, kwandiri, kunotsamira pamaitiro ekudzokorora. Tiri kutaura nezve mapatani uye molds. Iyo shell mold process, kana Croning process, ibasa repakati-vhoriyamu, yakaoma simbi uye alloy zvikamu. Inopa kupedzisa kurinani kwepamusoro uye kurongeka kwedimensional pane kukanda jecha, asi haisiriyo yepamusoro. Kwaunonyatso pinda munzvimbo chaiyo ndeyekudyara kwekudyara, iyo yakarasika-wax nzira. Apa ndipo panozviparadzanisa zvipfeko zve 'Pvt Ltd'. Iko kugona kudzora ceramic slurry, iyo stuccoing, iyo dewaxing choto paramita, uye yekupedzisira kudururwa-ndiyo orchestra. Kutsauka kudiki mukupisa kwekutanga-kupisa kweganda receramic kunogona kutungamirira kune mistruns kana misodzi inopisa muzvikamu zvitete. Ndiwo maitiro andakaona achiitwa nenyanzvi dzakagara kwenguva refu, kwete generalists.
Semuenzaniso, funga zvinhu zvakaita seCF8M isina tsvina kana duplex simbi. Kudurura izvi mukudyara kwekuseta kunoda kudzora kwakasimba pamusoro pemazinga ekusimba kudzivirira kudzima kuumbwa kwechikamu. Inowanikwa inogona kunyora zvinhu izvi, asi rutsigiro rwavo rwesimbi-kungave vachiita-mumba spectro ongororo, magadzirirwo avanoita masisitimu emagedhi eaya alloys-ndiko kutaura chaiko. Ini ndinorangarira purojekiti yechinhu chinoparadza chevhavhavha yemvura uko iyo spec inodaidzira yakasimba ferrite yemukati. Vatengesi vakati wandei ve 'Precision Casting' vakazvivimbisa, asi mumwe chete ane chiyero chakanyatsogadziriswa cheFischer anogona kupa macerts nebatch yega yega, zvichiratidza kutonga kunoenderana.
Apa ndipo apo nhoroondo yekambani inobatika. A firm like Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), ichicherekedza anopfuura makore makumi matatu mukukandira uye kugadzira, inoratidzira mamiriro ekunze ekutenderera kwemaitiro. Vanonyora shell mold uye kuisa mari kukanda zvakananga. Ndiwo mupiro wakanangana. Hurefu hwemakore makumi matatu hunoreva kuti vangangove vakadzokorodza kuburikidza nekushanduka-shanduka kwezvinhu - kubva pahuni kuenda kualuminium kusvika kune nekukurumidza-prototyped resin - uye vakagadzirisa kuderera kwezvinhu zvechimwe nechimwe. Iro ruzivo rwemasangano pamusoro pekuita kwepateni yewakisi maringe ne3D-yakadhindwa polymer imwe haisi mubhuku; zviri muhurongwa hwavo matanda.
The Critical Bridge: Kubatanidza Casting pamwe Machining
Heino gomba rakakura: kubata kukanda uye kugadzira semasilo akaparadzana. Iyo chaiyo-yakakandwa chikamu inowanzova padhuze-neti-chimiro, asi inoda nguva dzose machining ekuisa chisimbiso nzvimbo, tambo, kana kushivirira-kushivirira mabhora. Kana mupi wekukanda akasadzora machining, unogara nhaka yakakura yekubatanidza njodzi. Iyo machinist inogona kuwana nzvimbo yakaoma kubva pakutonhora kusingatarisirwe mukukanda, kana kudiki diki shanduko inosiya isina kukwana stock pane yakakosha flange. The blame game inotanga.
Yakabatanidzwa CNC machining haigone kutaurirana kune zvakakosha zvikamu. Kana imba yekukanda ichiitawo machining, vanogona kuronga maitiro ekukanda vaine machining datum mupfungwa. Vanogona kuwedzera stock painodiwa uye kuideredza kumwe kunhu. Kutaurwa kweQSY kwakajeka kweCNC machining padivi pemasevhisi avo ekukanda ibasa rakakura rekushandisa. Zvinoreva kuti vanogona kuita coordination yekuyeresa muchina (CMM) ongororo pane imwecheteyo setup inoshandiswa kugadzira, kuve nechokwadi chekuti chikamu chekupedzisira chinoenderana nekudhindwa kubva kune imwechete sosi yemutoro. Ndakaongorora zvivakwa uko kubatanidzwa uku hakuna musono; iyo yekukandira yekupedzisa sero inodyisa zvakananga mubhangi reCNC vertical machining centers, ine ma process vafambi anosanganisira ese ari maviri ekukanda nhamba dzekupisa uye machining tool offset matanda.
Muenzaniso unoshanda waiva pombi impeller mune nickel-based alloy (funga Inconel 718). Kukandira kwaida kutendeseka kwekumhanya kukuru kwekutenderera, asi iyo hydraulic profile yevanes yaida CNC milling kuti iwane inodiwa kupera kwepamusoro uye kushivirira kweprofile. Kutsvaga kukanda kune imwe 'Precision Casting Pvt Ltd' uye machining kune imwe kwakaunza kunonoka kwemavhiki matanhatu nekuda kwekusawirirana. Chidzidzo chacho chaive chakajeka: kukosha kuri mukubatanidzwa kwakatwasuka. Webhusaiti yemupi pa https://www.tsingtaocnc.com rinoratidza kugona kwakasanganiswa uku, kuri kutaura kupfuura zita rezita.
Material Nuances: Iyo Special Alloys Reality
Vazhinji vatengesi vanonyora 'special alloys' pane yavo pepa rekugona. Iri izwi rakafara rinogona kureva chero chinhu kubva kugadziridzwa 4140 simbi kusvika kune echokwadi superalloys. Kubatwa kwecobalt-based (semuenzaniso, Stellite) kana nickel-based alloys (seMonel) isangano rakasiyana kubva kune yakajairwa simbi isina tsvina. Zvinhu izvi zvinowanzoita viscous, zvinogara zvichipisa kuputika, uye zvinoda chaiyo yekudurura tembiricha uye mold pre-heats.
Dambudziko neizvi hakusi kungonyunguduka; ndiko kugadzirira kwese. Wax mapatani ekukandira kwekudyara kweaya alloys anowanzoda yakasarudzika geting kuti ive nechokwadi chekusimba. Iyo shell zvinhu zvinogona kuda rakasiyana refractory base, senge zircon, kuti rimire tembiricha yekudurura uye kudzivirira simbi-mold kuita. Imba ine ruzivo rwechokwadi mune izvi ichava nemitsara yejekiseni yewakisi uye makamuri ekuvaka magoko eaya alloys kudzivirira kusvibiswa. Kana ini ndichiona kambani yakaita seQSY ichinyatso kusheedzera cobalt-based uye nickel-based alloys, inoisa chiratidzo chezvivakwa zvakatsaurirwa. Hachisi chinhu chaunotamba nacho; mutengo wemari yezvipfeko zvechoto chakakodzera uye kudzora kusvibiswa kwekunyungudutsa zvinhu izvi zvakanyanyisa.
Kukundikana kazhinji kunobva pakuvabata sesimbi yakajairika. Ini ndinorangarira prototype inomhanyisa chikamu cheturbine chisimbiso apo iyo cobalt alloy yakadirwa mune yakajairwa silica-based shell yaiitirwa isina tsvina. Mhedzisiro yacho yaive yakashata pamusoro pekuita uye kuyera, izvo zvakazokonzera kutadza kukuru panguva yekugadzira sezvo chishandiso chakarova danda rakasvibiswa. Chikonzero chikuru chaive nzira yekudimbudzira. Nyanzvi haimbofa yakamboita chikanganiso ichocho.
Pamusoro Pekupedzisira uye Dimensional Magedhi: Iwo chaiwo Metrics
Precision inoverengwa. Mukukanda, ndeye CT (Cast Tolerance) zviyero uye kushata kwepamusoro (Ra). Iyo yakajairwa indasitiri inonongedza ndiyo ISO 8062 CT standard. Chitoro chinoti 'chaizvo' chinofanira kukwanisa kukuudza kuti ndeipi CT nhanho yavanogara vakabata kune yakapihwa chikamu saizi uye maitiro. Yekudyara kwekudyara, CT 4-6 inojairwa kune akawanda zviyero. Kubata CT4 pane imwe nzvimbo yakaoma chiratidzo chekutonga kwepamusoro.
Kupedzisa kwepamusoro ndeimwe yekupa. As-cast surface kubva kune yepamusoro-mhando goko kana yekudyara maitiro inogona kuwana Ra 3.2 μm kana zvirinani. Asi iwe unofanirwa kubvunza: ndiyo yakajairika kukosha kana yakanakisa-kesi? Uye pane geometry ipi? Nzvimbo yakati sandara iri nyore; nzvimbo yemukati yediki-dhayamita, musara wakakombama ndiyo bvunzo chaiyo. Apa ndipo pane basa rekuzvionera wega. Panguva yekushanya kwezvivakwa, ndinogara ndichikumbira kuona zvisingaite mu-process zvikamu uye mishumo yekuongorora yekupedzisa pane zvemukati maficha. Nhamba dziri pamushumo dzinoda kuenderana netactile uye yekuona kunzwa kwechikamu.
Mazhinji makambani e'Precision Casting' anotadza pamagwaro anowirirana. Ivo vanogona kugadzira imwe yakanaka sampu, asi yekutanga chinyorwa chekuongorora rondedzero uye maitiro ekudzora hurongwa hwekugadzira kumhanya ndizvo zvine basa. Mushandi ari pamutemo achave nekufamba kwakajeka: kusangana kwewakisi -> chinyorwa chekutanga cheki cheki -> chivakwa chegoko -> pre-dururira goko rekuongorora -> kudurura -> kugogodza -> kucheka-kubvisa -> yekupedzisira dimensional uye yekuona kuongorora. Nhanho imwe neimwe inofanira kuva nenzvimbo dzekutarisa. Kusavapo kwekuyerera kwakanyorwa uku mureza mutsvuku, zvisinei nekuti kambani inodaidzwa sei.
