Iwe unonzwa 'chaiyo simbi yekukanda' uye nekukurumidza funga nezve kushivirira kwakasimba, nzvimbo dzisina kukanganisa, pamwe zvinhu zvemuchadenga. Ndiyo danho rekutengesa. Chokwadi chiri pauriri hwenheyo nhaurirano inogara iripo pakati peiyo yakanaka geometry pamuenzaniso weCAD uye fizikisi yakasindimara yesimbi yakanyungudutswa. Iyo chaiyo chaiyo haisi mukuyera chete; zviri mukufanotaura kuti iyo 316L kana yakaderera-alloy simbi ichaita sei kubva painosiya ladle kusvika yatonhorera mukuzunza. Vazhinji vekutenga zvinhu vakomana vanogadzirisa pane yekupedzisira dimensional report, vachishaya iyo yese mainjiniya maitiro anoita kuti chirevo ichocho chigoneke. Ndipo panowanikwa mari chaiyo nekukosha.
Iyo Shell Game: Kupfuura Kungofanana Mold
Vazhinji vanosanganisa kurongeka nekukandira kwekudyara, iyo yakarasika-wax maitiro. Yakanakisa, asi kune huwandu hwezvikamu zvesimbi, kunyanya izvo zvine mwero kuomarara uye nepamusoro vhoriyamu zvinodiwa, shell mold casting ndiro bhiza risingasviki. Kuzvitoro zvakaita seQingdao Qiangsenyuan Technology Co., Ltd. (QSY), kwavave vari pano kweanopfuura makore makumi matatu, unoona sarudzo yacho isiri yechokwadi. Zvinoshanda. Shell kuumba, uchishandisa resin-yakavharwa jecha, inokupa iwe yakanakisa chiyero. Iyo mold rigidity inodzora kukanganisa zvirinani kupfuura zvinotarisirwa nevakawanda, uye kupedzisa kwepamusoro kunogona kurova Ra 12.5 μm kana zvirinani kana ukagadzirisa ma paramita ako. Haisi nguva dzose nezve kupedzisa kwakanakisa, asi nezve yakanyanya kusimba uye inodzokororwa maitiro ekuita kwechikamu.
Chinokosha chiri pateni. Iyo yemhando yepamusoro yesimbi pateni, yakagadzirwa kusvika pakukwana, ndiyo isingagone kutaurirana pekutangira. Chero kukanganisa pano kunodzokororwa zvakanyanya. Ndakaona mapurojekiti achitadza nekuti mumwe munhu akaedza kuchengetedza pamutengo wepateni. Ukobvu hwegoko hahuna kufanana zvakare - hwakaiswa zvine hungwaru. Zvikamu zvakakora apo kuvhunduka kunenge kuri kwepamusoro panguva yekudira. Rudzi irworwo rweruzivo rwunobva kune ruzivo rwakadhindwa, kwete bhuku remanyorero chete. Iwe unodzidza 'kuverenga' goko mushure mekudonha, uchitsvaga akatsemuka akatsemuka kana makwapa akapfava anoratidza mune ramangwana scabbing kana simbi kupinda.
Kwazvinoita hunyengeri ndeyemukati machenera kana macores. Pasimbi, core assembly mugoko regoko inoda kubatwa nachiremba. Kusarongeka nehafu yemirimita kunogona kushandura ndima inotonhodza kuita isina chinhu. Nzira yeQSY yekubatanidza CNC machining post-casting inowanzo chengetedza zvikamu izvi. Ivo vanogona muchina kuita chinhu chakakandwa, kugadzirisa diki musimboti shanduko, asi dhizaini inofanirwa kubvumira izvo. Inhaurirano inofanirwa kuitika isati yatemwa maitiro ekutanga: Ndekupi kwatingakwanise kusiya imwe stock yekuchenesa-up machining pass? Ndiko kubatanidzwa kwekugadzira kufunga.
Material ndiyo Silent Variable
Simbi haisi simbi chete. Kudira kabhoni simbi maringe nenickel-based alloy seInconel 718 inyika yakasiyana. Iko kurongeka kwekukandira kunoenderana zvachose nemaitiro ekusimba kwechinhu. Shrinkage factor haina mutsara. Yakareruka lever ruoko muCF8M isina tsvina ingangoda yekudyisa kaviri kuwanda kwechikamu chacho kudzivirira shrinkage porosity muhubhu. Haufungi izvi; iwe unozvidzidza kubva mukucheka uye kuongorora mazana ezvibairo prototypes.
Apa ndipo panodiwa makore makumi matatu kumashure kweiyo foundry. Vakavaka raibhurari yepfungwa, rudzi rwezivo yakanyarara. Vanoziva kuti rimwe giredhi re duplex stainless rinowanzo 'kudhonza' zvakanyanya pamakona akapinza, achida fillet radius yakakura kupfuura ingadiwa nemugadziri. Ivo vanosundidzira kumashure padhirowa, kuti zvisave zvakaoma, asi nekuti vanoziva kuti kudzingirira isingaite se-yakandwa radius inotungamira mukupisa kubvarura, kubvarura chikamu. Iyo chaiyo inowanikwa nekusakanda kumucheto chaiko kwezvinogoneka.
Special alloys, senge cobalt kana nickel-based akanyorwa muQSY's portfolio, wedzera imwe layer. Kuyerera kwavo kwakasiyana, ivo vanowanzodirwa patembiricha yakakwira, uye vanoita zvakanyanya nemhepo yekuumbwa. Yako gating uye venting system inova yakakosha. Iyo mold isina mhepo isina mhepo inokonzeresa mhirizhonga, kuteya gasi uye kugadzira kuremara kwepamusoro uko hakuna huwandu hwemachining hunogona kugadzirisa zvizere. Iyo chaiyo inorasika simbi isati yanyatsozadza mhango.
Iyo CNC Handshake: Iko Kukandira Kunosangana Nechokwadi
Hapana kwakakomba kukanda simbi kushanda kunomira pa shakeout. Iyo as-cast state is pre-form. Iwo akavimbiswa zviyero zvinobva kuCNC machining. Ichi ndicho chinongedzo chakakosha. Imba ine mu-house machining, sezvaunoona pairi tsngtaocnc.com, ine mukana mukuru. Iwo machinists uye mainjiniya ekutanga vanotaura mutauro wakafanana. Vanogovana pasi rimwechete.
Kuvhiya kwekutanga kunowanzo kugadza datum. Magadzirirwo aunoita mbichana mbichana ndizvo zvese. Iwe unofanirwa kutsvaga nzvimbo dzakadzikama uye dzinomiririra chikamu chinoshanda geometry. Dzimwe nguva, taitokanda madiki, mapedhi ezvibairo pazviso zvisina kutsoropodza kuti tive neshasha, inogoneka pamusoro pekutanga vise grip. Iro ruzivo rwakazvininipisa, asi runoita kuti machining ese anotevera anotaurwa nemazvo, kukiya mukati. kunyatsokandira simbikugona 's.
Ndinoyeuka hydraulic valve body, yakaderera-alloy simbi yekukanda. Iyo as-cast bore yaive mukati me1mm yehukuru hwekupedzisa, asi chinzvimbo chechokwadi chemharadzano dzechiteshi chakawanda ndiyo yaive dambudziko. Nekuva neCNC machining mukati-mumba, vaigona kuongorora chikamu chakakandwa, gadzirisa machining anorongedzerwa zvishoma kuti atsivise kusiyanisa kwekutanga, uye vachirova iyo yechokwadi chinzvimbo callouts pane yakadhindwa. Uku hakusi kugadzirisa kukanda kwakashata; iri kutsiva yakasikwa, inotenderwa mutsauko wekukandira kuti uwane mhedzisiro yenet-chaizvo. Ndiwo maonero akazara ekugadzira.
Kukundikana Ndiwo Mabhuku Chaivo
Iwe unodzidza zvakawanda kubva muchikwata chakaraswa pane churu chakakwana zvikamu. Pakutanga, takava nekumhanya kwepombi dzimba muCA15 martensitic isina tsvina. Madimesheni acho aive akanaka, kumeso kwaive kwakachena. Yapasa ongororo yekutanga. Asi mukuyedzwa kwekumanikidza, takange tave nekuvuza pamadziro aiita kunge akasimba. Cheka iyo yakavhurika, uye pakanga paine bvudzi network network ye micro-shrinkage, isingaoneki kubva kunze. Mupari wemhosva? Tembiricha yekudurura yaive yakanyanya kukwirisa, ichidzingirira mvura iri nani kuzadza zvimwe zvikamu zvitete, asi yakachinja kutevedzana kwekusimbisa. Takatonhodza kudira, ndokudzikisira pasi, uye tikawedzera kutonhora, kwenzvimbo kumadziro ane dambudziko. Dambudziko ragadziriswa. Iyo spec sheet yakangoti CA15, ASTM A743. Haina kutaura kuti yodirwa sei.
Kumwe kutadza kwechinyakare kuwedzeredza-kugadzira kune chaiyo. Mutengi akamboda kuti isingashande yemukati nzvimbo kuti ikandwe kune Ra 6.3 μm kupera uye ± 0.1mm kushivirira. Yaidhura mune zvenyeredzi. Takaitirana nharo pamusoro pekugadzira, asi vakaramba. Mutengo wegoho wakaipa, pamwe 30%. Pakupedzisira, pashure pokunge mutengo wapfuura, vakabvuma kutirega tichiikanda rougher toigadzira. Mutengo wakadzikira ne60%, uye goho rakapfura kusvika pa98%. Chidzidzo: Kurongeka kwechokwadi kushandisa nzira kwayo kune zvinodiwa. Kwete pese pese pa a kunyatsokandira simbi inoda kunyatsokandwa.
Iyo Pragmatic Supply Chain: Zviri Zvekuenderana
Kana iwe uchigadzira chaiyo yekukanda, kunyanya kubva kune mumwe wako seQSY, hausi kungotenga chikamu. Iwe uri kutenga yavo process control ledger. Kubatana pamusoro pe500-chikamu kurongeka kwakakosha kupfuura kukwana kwakakwana kwemuenzaniso mumwe chete. Vanogona here kubata iyo yakafanana pamusoro pekupedzisira pachikamu 1 uye chikamu 500? Ko yavo metallurgical report inoratidza yakafanana chemistry batch after batch?
Izvi zvinouya kuzvinhu zvemazuva ano. Sand reclamation systems. Tembiricha matanda ekupisa kwese. Calibration zvirongwa zve spectrometers. Webhusaiti yekutanga inogona kunyora maalloys ese ari munyika, asi humbowo huri mugwaro rekuita ravanogona kupa. Chinhu chinonyanya kusimbisa chinogona kuratidzwa nemutengesi kuti hausi sampuli inopenya; ndiyo yakasakara, inogara yakazadzwa-out process control chart.
Pakupedzisira, kunyatsokandira simbi ibhiriji pakati pechinangwa chekugadzira uye chokwadi chemuviri. Haasi mashiripiti. Kurangwa kwakasimba, kwehunyanzvi, uye kwakadzama ruzivo uko kubudirira kunoyerwa mugoho rinodzokororwa uye chivimbo chinyararire chekuti chikamu chinobuda mubhokisi rekutumira chichashanda, nguva dzese. Makambani anogara, ayo ane makumi emakore ari pasi pebhanhire ravo, anonzwisisa kuti kurongeka kuri muhurongwa, kwete chete munguva yekudururwa.
