1- Chii chinonzi Investment Casting?
Investment Kudzingwa, iyo inozivikanwa zvakare yakarasika wakisi kukanda kana kunyatso kukanda, zvinoreva kuumbwa kwekramiki kwakakomberedza iwo wax mapatani kugadzira yakawanda kana imwechete chikamu chimuvhu kuti igamate yakaumbwa nesimbi. Maitiro aya anoshandisa anoshandiswa jekiseni rakaumbwa wakisi pateni maitiro ekuwana mafomu akaomarara aine hunhu hwepasirese. Kugadzira chakuvhe, wakisi pateni, kana sumbu remapatani, inonyikwa muzvinhu zvedongo kanoverengeka kuvaka gogo gobvu. De-wax maitiro anozoteverwa neiyo shell yakaoma maitiro. Iyo yakisi-shoma ceramic ganda inogadzirwa. Simbi yakanyungudutswa inozodururwa mumakanda emakemikari kana sumbu, uye kana yangomarara uye yatonhora, zvedongo goko rinovhunika kuratidza chinhu chekupedzisira chesimbi. Precision inivhesitimendi castings inogona kuwana yakasarudzika kunyatso kweese madiki uye makuru ekurasa zvikamu munzvimbo dzakasiyana siyana dzezvinhu.
2- Ndeapi Iwo Makomborero Ekudyara Mari?
✔ Yakanaka kwazvo uye yakapfava pamusoro pekupedzisira
✔ Kusimba kwekuita kushivirira.
✔ Maumbirwo akaomarara uye akaomarara ane dhizaini yekuchinja
✔ Kugona kukanda matete matete saka chakareruka kukanda chinhu
✔ Wide sarudzo yesimbi yesimbi uye alloys (ferrous uye isiri-ferrous)
✔ Dhizaini haina kudikanwa mune dhizaini dhizaini.
✔ Deredza kudiwa kwechipiri michina.
✔ Low zvinhu tsvina.
3- Ndeapi Matanho eInvestment Kudzingwa Maitiro?
Munguva yekudyara nzira yekukanda, wakisi pateni yakaputirwa neceramic zvinhu, izvo, kana zvikaomeswa, inotora iyo yemukati geometry yekuda kukanda. Muzviitiko zvakawanda, zvikamu zvakawanda zvinokandirwa pamwechete kuti zviite nemhando yepamusoro nekubatanidza mapatani ega ega kune kamuti kemusara kanonzi sprue. Wakisi inonyungudika kunze kwepateni - ndosaka ichizivikanwa seyakarasika nzira yewakisi - uye simbi yakanyungudutswa inodirwa mukati mevhu. Kana simbi ikasimbiswa, iyo ceramic mold inozununguswa, ichisiya padyo mambure chimiro chekuda kukanda, kuchiteverwa nekupedzisa, kuyedza uye kurongedza.
4- Ndeapi maInvestment Castings Anoshandiswa Kune?
Investment castings anoshandiswa zvakanyanya mumapombi nemavhavha, mota, marori, ma hydraulic, marori eforklift uye mamwe maindasitiri mazhinji. Nekuda kwavo kwakasarudzika kukanda kushivirira uye exellent kupedzisa, iyo yakarasika wax castings anoshandiswa zvakanyanya uye zvakanyanya. Kunyanya, iyo isina simbi simbi yekudyara castings inoita basa rakakosha rakakosha mukuvaka zvikepe nemagwa nekuti vane yakasimba anti-ngura kuita.
5- Ndeipi Kukanda Kushivirira Iyo Yako Yekusimba Inogona Kusvikira neInvestment Kukanda?
Sekureva kweakasiyana bhainda zvinhu zvinoshandiswa kugadzira iro dura, iyo yekudyara kukanda kunogona kukamurwa kuita silika sol kukanda uye mvura girazi kukanda. Iyo silica sol inivhesitimendi kukanda maitiro vane zvirinani ndeiya yakaita Kukanda Tolerances (DCT) uye Geometrical Kukanda Tolerances (GCT) pane mvura girazi muitiro. Nekudaro, kunyangwe neyakafanana nzira yekukanda, iyo Kushivirira Giredhi ichave yakasiyana kubva kune yega yega cast alloy nekuda kwavo kwakasiyana castability.
Yedu foundry inoda kutaura newe kana iwe uine chakakosha chikumbiro pane anodikanwa shiviriro. Pano pane anotevera ndiwo akajairwa shiviriro giredhi isu aigona kusvika zvese nesilica sol kukanda uye mvura girazi kukanda maitiro zvakasiyana:

6- Ndeapi Iwo Makero Ekukura Ekudyara Kukanda Zvikamu?
Investment castings inogona kugadzirwa mune ese maalloys kubva pachikamu cheyunce, yemazino brace, kusvika kune anopfuura chiuru lbs. (453.6 kg) yezvikamu zvakaoma zveinjiniya. Zvidiki zvidiki zvinogona kukandwa pamazana pamuti, nepo kurema kukanda kazhinji kuchigadzirwa nemuti wega. Kurema muganho wekudyara kukanda kunoenderana neforoma yekubata michina pane yekukanda chirimwa. Izvo zvivakwa zvinokanda zvikamu zvinosvika makumi maviri lbs. (9.07 kg). Nekudaro, zvivakwa zvizhinji zvemumba zviri kuwedzera kugona kwavo kudurura zvikamu zvakakura, uye zvikamu mu20-120-lb. (9.07-54.43-kg) renji iri kuve yakajairika. Chiyero chinowanzoshandiswa mukugadzira mari yekudyara ndeye 3: 1-yega yega 1-lb. (0.45-kg) yekukanda, panofanirwa kuve ne3 lbs. (1.36 kg) kumuti, zvinoenderana negoho rinodiwa uye saizi yechinhu. Muti unogara uchifanira kuve wakakura kupfuura chinhu, uye chiyero chinovimbisa kuti panguva yekukanda nekusimbisa maitiro, gasi uye kudzikira kunozoguma mumuti, kwete kukanda.
7- Nderupi Rudzi rweSurface Rinopedzwa Rinoburitswa neInvestment Kukanda?
Nekuti iro zvedongo goko rakaunganidzwa rakatsetseka mapatani anogadzirwa nekujovera wakisi mune yakabwinyiswa aluminium kufa, yekupedzisira kukanda kupedzisa kwakanakisa. Yakapetwa zana nemakumi maviri neshanu yemamirioni akapera uye akagwinya (63 kana makumi matatu nemaviri) anokwanisika nemabasa ekupedzisa epashure. Individual simbi yekukanda zvivakwa zvine yavo zviyero zvepamusoro pemvura, uye zvivakwa mudonzvo uye dhizaini mainjiniya / vatengi vanokurukura izvi kugona pamberi pekushandisa tooling yaburitswa. Mimwe miitiro inoenderana nechinhu-chekupedzisira-kushandisa uye yekupedzisira cosmetic maficha.
8- Mari Inokandwa Inodhura Here?
Nekuda kwemitengo uye basa nehusiku, mari yekudyara castings kazhinji ine yakakwira mutengo kupfuura yakakwenenzverwa zvikamu kana jecha uye zvechigarire muforoma kukanda nzira Nekudaro, ivo vanogadzirira iyo yakakwira mutengo kubudikidza nekudzikiswa kwemashini inowanikwa kuburikidza se-kukanda padhuze-net-chimiro kushivirira. Mumwe muenzaniso weizvi ndezvekuvandudza mumotokari rocker maoko, ayo anogona kukandwa pasina kana michina inodiwa. Zvikamu zvakawanda zvinoda kugaya, kutendeuka, kuchera uye kukuya kupedzisa kunogona kuve kudyara kukanda ne0.020-0.030 chete yekupedzisira stock. Kupfuurirazve, kukanda kwekudyara kunoda mashoma madhiri emakona kubvisa mapatani kubva mukushandisa. uye hapana kunyorwa kunodiwa kubvisa simbi yakakandwa kubva muhomwe yekudyara. Izvi zvinogona kubvumidza kukanda ine 90-degree angles kuti igadzirwe pasina yekuwedzera michina kuti uwane iwo maAngles.
9- Ndeapi Maturusi uye Mapuratifomu Midziyo Inodikanwa kune Yakarasika Wax Kukanda?
Kugadzira iyo wax mafomu mapatani, yakatsemurwa-mhango simbi kufa (ine chimiro chekupedzisira kukanda) ichada kugadzirwa. Zvichienderana nekunetseka kwekukanda, kusanganiswa kwakasiyana kwesimbi, zvedongo kana kusungunuka macores kunogona kushandiswa kubvumira iyo yaunoda kugadzirisa. Mazhinji ekushandisa ekudyara mari yekurasa mari iri pakati pe $ 500- $ 10,000. Rapid prototypes (RP), senge stereo lithography (SLA) mhando, zvakare inogona kushandiswa. Iwo eRP mamodheru anogona kugadzirwa mumaawa uye otora pane chaiyo chimiro chechikamu. Izvo zvikamu zvePRP zvino zvinogona kuunganidzwa pamwe chete uye zvakaputirwa neceramic slurry uye zvinopiswa zvichibvumidza mhango kuti iwane prototype investment cast chikamu. Kana kukanda kwacho kwakakura kudarika envelopu yekuvaka, akawanda maRP-chikamu chezvikamu anogona kuitwa, akaunganidzwa kuita chikamu chimwe, ndokukandwa kuti awane yekupedzisira prototype chinhu. Kushandisa zvikamu zvePR hazvina kukodzera kugadzirwa kwepamusoro, asi zvinogona kubatsira dhizaini dhizaini kuongorora chikamu chekururamisa uye chimiro, kukwana uye kushanda usati waendesa chishandiso odha.
