Paunonzwa 'chaiyo yekukanda zvikamu zvekugadzira', pfungwa zhinji dzinosvetuka dzakananga kushiviriro uye zvinhu certs. Ndiyo yekutanga, tikiti remutambo. Nyaya chaiyo, iyo inoparadzanisa mutengesi anoshanda kubva kune mumwe wepachokwadi mudiwa, inoitika munzvimbo dzegrey pakati penhamba idzodzo-mukududzira kwechinyorwa chekudhirowa, kubata kwedhizaini kusajeka, kana sarudzo yekufonera mutengi na2 AM nekuti batch rechoto raitaridzika zvishoma-ruvara. Hazvisi zvekungoita chikamu; ndezvekunzwisisa kushushikana kusingataurwe kwazvichaita.
Iyo Shell Game: Kupfuura Kungofanana Mold
Shell mold casting inodzika senge inodhura-inoshanda yepakati pasi, uye ndizvo, asi izvo zvinodzikisira nuance yayo. Iyo silica jecha neresin musanganiswa-iyo 'shell' - kuenderana kwayo ndicho chinhu chose. Kunyanya brittle, uye iwe unowana inclusions kana mold kuputika panguva yekudira. Kunyanya kuchinjika, uye kugadzikana kwedimensional kunobuda nepahwindo. Takadzidza izvi kare nebhechi repombi dzimba dzemutengi. Zvikamu zvakapfuura macheki ekutanga asi zvakatadza kumanikidza kuyedzwa panzvimbo yemutengi. Mupari wemhosva? Microscopic kukukurwa kwejecha mumhanyi sisitimu yatakanga tisina kuverengera, iyo yakashandura mafambiro ekuyerera zvakakwana kuti iite mhirizhonga uye porosity muzvikamu zvakakosha. Iyo spec sheet yakati 'shell mold casting,' asi kutadza kwakati isu hatisi kunzwisisa mafambiro emvura emaitiro edu eiyo chaiyo geometry.
Ndipo panouya makore makumi matatu, sepanzvimbo yakadai Qingdao Qiangsenyuan Technology Co., Ltd. (QSY). Nguva iyoyo haisi nhamba chete; iraibhurari yeizvi zvidiki-kutadza uye kugadzirisa. Zvinoreva kuti vangangoona zvinoitika kumusanganiswa wegomba muhunyoro hwepamusoro zvichienderana nemamiriro ekunze akaoma, uye vakagadzirisa pre-heat cycles zvinoenderana. Irwo ruzivo rwemadzinza rusingaite kune bhurocha rekutengesa.
Investment casting, kana kurasika-wakisi, ndiyo imwe mbiru. Kukwezva kuri padhuze-net-shape kuomarara, asi musungo uri kufunga kuti zvese zvakaoma zvakaenzana. Iro rakatetepa, rakatambanudzwa flange uye gobvu, chunky hub pachikamu chimwe chete chinotonhorera pamitengo yakasiyana. Iwe unogona kuve newakisi jekiseni rakakwana uye pristine ceramic goko, asi kana iyo yekusimbisa simulation yakadzimwa kana kufuratirwa, uri kubhejera. Takambodurura bhechi rakanaka remapombi esimbi isina tsvina, ndokuzongowana pakatsemuka bvudzi mumablades mushure mekupisa-kupisa. Kushungurudzika kwakavharirwa mukati panguva yekutonhora; mhinduro yanga isiri nani wakisi, asi kugadziridzwa patsva kwegeji system yekudzora kupisa kwemagetsi, chimwe chinhu chaida kugara pasi nainjiniya wemutengi uye nekuchimbidza kubvumirana.
Iyo Material Maze: Alloys Haana Kusikwa Akaenzana
Simbi isina tsvina. Inonzwika zvakananga. Asi 304L maringe ne316L yekushandisa mugungwa? Ndiko kufona kuri pachena. Mafaro chaiwo anotanga ne'special alloys'-iyo nickel-based uye cobalt-based. Izvi zvinowanzotsanangurwa kune zvakanyanya nharaunda: kupisa kwakanyanya, ngura, kupfeka. Kubata kwacho ndekwekuti, maitiro avo panguva yekukanda hapana chinhu kunze kwechiyero. Vane mapoinzi ekunyungudika, akasiyana shrinkage maitiro, uye anogona kuve anonzwa kuronda zvinhu.
Ndinoyeuka chirongwa chinosanganisira cobalt-based alloy yendiro yekupfeka. Iyo chemistry yaive yekufungidzira, michina yakaedzwa zvakanaka pamakuponi. Asi mumunda, chikamu chakapfeka zvisina kuenzana. Mushure mekuwanda-kukwenya musoro uye simbi yekuongorora, zvakazoitika kuti nyaya yaive yekugovera carbide. Mwero wekutonhodza watakashandisa, waive wakajairwa wesimbi yemidziyo, wanga usina kunyatso kusimudzira yunifomu, yakanaka carbide network mune iyi cobalt alloy. Isu taifanira kugadzira yakarongedzwa kutonhora protocol, ingangoita yekupisa-yekupisa yekurapa regimen, kuti tiwane iyo microstructure chaiyo. Dhirowa yemutengi yakangoti Co-Cr-W alloy, ASTM XXXX. Chokwadi chekugadzira chaive chirongwa chemavhiki maviri chekuvandudza.
Apa ndipo pane basa remugadziri wezvinhu. Chitoro chinongoti hongu, isu tinoita nickel alloys yakasiyana neiyo yakatsaurira marashi echoto uye setups ye thermocouple kwavari, kudzivirira kusvibiswa. Zviri muzvinyorwa zvavo CNC machining process, futi. Kugadzira simbi yakaoma yesimbi chinhu chimwe; Kucheka pane kunaya-kuomesa nickel alloy kunoda akasiyana maturusi ejometri, mafidhi, uye kumhanya kudzivirira kushanda-kuomesa nzvimbo kuita isingachinjiki.
CNC: Iko Kukandira Kunosangana Nenyika
Ichi ndicho chikamu chekugadzira-kana-kuputsa. Iwe unogona kudurura kukanda kwakakwana, asi kana machining asina kubatanidzwa mukuronga kubva pakutanga, wanyura. Izvo ndezvekusarudzwa kwedatum, mvumo yemasheya, uye kunzwisisa 'hunhu' hwekukanda.
Dambudziko rinowanzoitika kubata kukanda sechinhu chakafanana chestock. Hazvisizvo. Panogona kunge paine kushomeka kushoma pazasi peganda munzvimbo imwe, kana kusara kwekushushikana kubva mukutonhodza. Kucheka kunorema, kwehasha kwekutanga panzvimbo isiriyo kunogona kukanganisa chikamu chacho kana kubvarura zvinhu. Takagadzira muviri mukuru wevharuvhu kamwe chete, ductile iron casting. Oparesheni yekutanga yaive yekutarisana neflange yaikwira. Patakangosunungura kumanikidza kwe clamping, chikamu chakakotama. Iyo yekuzorodza yekushushikana kubva pakubvisa iyo ganda repamusoro yakabvumira latent casting stress kugovanisa. Isu taifanira kuteedzera zvakare maoparesheni, tichitora akareruka, kuenzanisa kucheka kuti zvishoma nezvishoma kuunza chikamu mukugadzikana.
Zvebasa rakazara precision kukanda zvikamu mugadziri, machining harisi dambudziko remukontrakta; kuenderera mberi kwekukandira. PaQSY, semuenzaniso, kuve nezvose kukanda uye CNC machining pasi pedenga rimwe chete haisi yezvigadzirwa. Zvinoreva kuti timu yekugadzira inoziva iyo yakajairwa shrinkage yeyavo yekudyara castings, kana iwo angangove akaomeswa mavara mumigove yavo mold zvidimbu. Ivo vanogona kusiya imwe stock munzvimbo inozivikanwa ine dambudziko pasina kubvunzwa. Iyo yemhinduro loop pakati peiyo yekutanga pasi uye CNC shopu haionekwe kune mutengi asi yakakosha kune mhedzisiro.
Mukaha weKukurukurirana: Dhirowa vs. Chinangwa
Izvi zvinogona kunge zviri izvo zvakanyanya kukonzera kutema kwemusoro. Dhirowa igwaro remutemo uye rehunyanzvi, asi ishanduro isina kukwana yechinangwa cheinjiniya. Kudaidzira kwepamusoro, chinyorwa chisina kujeka nezve radius kumativi ese, nzvimbo yekuchinja isina kutsanangurwa - idzi ndidzo nzvimbo dzekuberekesa dzekuodzwa mwoyo.
Ndakaona madhirowa a precision casting chikamu chine kushivirira kwakasimba kupfuura izvo izvo base casting process inogona kubata nekuvimbika, pane zvisiri-akakosha maficha. Kureva upofu kune musungo. The professional move is to pick the phone. Isu tinoona izvi +/- 0.1mm kushivirira pane uyu mukuru anokwira. Iko ndiko kurongeka, kana kuti kukwenenzverwa? Nekuti kana iri yemvumo, tinokwanisa kubata yakawedzera hupfumi se-kukanda kushivirira uye kuvimbisa kuti inokodzera chikamu chako chekubatana. Hafu yenguva, injiniya anoonga mubvunzo; vangadai vakakopa udzame kubva kune mumwe mufananidzo. Imwe hafu, inofumura chinhu chakakosha chinoda imwe nzira, sekufamba kune chaiyo-yakagadzirwa pamusoro.
Ndezvekujekeswa kweproactive, kwete kungouraya. Webhusaiti yemugadziri, senge tsngtaocnc.com, inogona kuratidza kugona, asi bvunzo chaiyo iri mune idzi pre-odha dialogue. Vanobvunza mibvunzo ine njere here? Ivo vanokurudzira dhizaini yekugadzira (DFM) tweaks inorerutsa maitiro pasina kukanganisa basa? Ndiwo mucherechedzo wechiitiko.
Kukundikana seCurriculum
Hapana mubhizinesi iri ane rekodhi yakakwana. Vaunoda kushanda navo ndivo vane danda rekukundikana rakanyatsoongororwa. Mugadziri akanaka haavanze izvi; vanoita zvidzidzo.
Isu takava nenjodzi yekutanga nekutevedzana kwealuminium-bronze investment castings. Vakaramba vachiratidza scattered micro-porosity. Takaongorora zvese: wakisi, goko, tembiricha yekudurura, dewaxing. Pakupedzisira, mugadziri wekare akabvunza nezve mwando munzvimbo yekuchengetera yemhando yepamusoro wakisi. Yaive yakakwirira. Iwo mapatani akange atora mwando wakakwana zvekuti panguva yekudonha (steam autoclave), mvura yakashanduka kuita chiutsi mukati megoko receramic zvine chisimba, ichikuvadza zvishoma kupera kwayo. Kugadzirisa kwaive nemamiriro ekunze-inodzorwa pateni yekuchengetedza. Chinhu chidiki, chisiri pachena.
Ndiro rudzi rweruzivo rwegranular, rwakakunda zvakaoma runotsanangura mashandiro akura. Ndosaka pakuwongorora a precision kukanda zvikamu mugadziri, iwe unofanirwa kubvunza kwete kungozvigona here izvi? asi ndedzipi njodzi nhatu dzepamusoro dzaunoona nechikamu ichi, uye ungadzideredza sei? Mhinduro yavo ichakuudza kupfuura chero chitupa pamadziro. Zviri mukuzengurira vasati vapindura, nzira yavanonongedza nayo kune chimwe chinhu pamufananidzo wako-ndiko ruzha rwechiitiko chaicho kufunga zvinonzwika.
