Vanhu vakawanda pavanonzwa 'gray cast iron mechanical parts,' vanofungidzira chimwe chinhu chinorema, chakachipa, uye chiri nyore. Ndiko kukanganisa kwekutanga. Chokwadi chakanyanya kuwanda, uye kuita zvisizvo pauriri hwechitoro kunoda mari chaiyo nenguva.
Bhiza Rebasa Risinganzwisisike
Ngativei zvakajeka: grey iron haina kusarudzwa nekuda kwekusimba kwayo. Iwe unoishandisa kune yayo yekunyorova simba uye kupfeka kuramba. Ndakaona dhizaini yakawandisa apo mumwe munhu anodoma simbi inodonhera kana simbi yeimba kana base, achidzingirira nhamba yesimba repamusoro papepa rekuona, asi gungano rese richizunguzika seforogo yekugadzira kana kupfeka nguva isati yakwana panzvimbo dzinotsvedza. Ma graphite flakes mu gray iron chombo chayo chakavanzika. Ivo vanoita sevakavakwa-mukati vibration dampers uye vanopa mafuta ekuzora. Icho chinhu chinokunda pasi pekumanikidzwa, kwete tension. Kana chikamu chako chiri kunyanya kuona mitoro inomanikidza uye ichida kugara yakanyarara uye yakagadzikana, grey iron ndiyo inowanzova yakangwara, ine hupfumi sarudzo.
Apa ndipo panobva panyanya kukosha ruzivo nezvenzira yekuvamba. Mwero wekutonhora panguva yekusimba unodzora zvakananga saizi yegraphite flake uye kugovera, iyo inozotaura iyo yekupedzisira zvivakwa. Chikamu chine gobvu chikamu uye chikamu chakaonda chakatonhodzwa nenzira imwechete chichava nema microstructures akasiyana. Ini ndinoyeuka batch yemashini ekushandisa mabhesi atakawana makore apfuura ayo akagadzira kuoma kusingaenderane panzira inokwirisa nzvimbo. Dambudziko rakanga risiri giredhi rezvinhu; kwaiva kuiswa kwezvikwiriso uye tembiricha yekudurura, izvo zvaitungamirira kuchando mune dzimwe nzvimbo uye graphite yakapfava mune dzimwe. Dhirowa yakangoti Kirasi 30 Grey Iron, asi izvo zvanga zvisina kukwana. Isu taifanira kushanda neiyo foundry pane pateni dhizaini uye gating system.
Makambani anga ari mumutambo wekukanda kwemakumi emakore, senge Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), nzwisisa izvi mukati. Neanopfuura makore makumi matatu ekukandira uye kugadzira, ivo vaona idzi misungo. Paunenge uchitsvaga yavo portfolio pa tsngtaocnc.com, hausi kungotarisa zvikamu zvapera; uri kutarisa kunzwisisa kwakadzama kwemaitiro. For grey cast iron mechanical parts, izvi zvinoreva kuziva nzira yekugadzira mold uye kutonga nzira kuti uwane chimiro chakanaka munzvimbo dzakakodzera, kunyanya kune maumbirwo akaoma.
Machining: Panowanikwa Dambudziko Rechokwadi
Kukandira ihafu yenyaya. Iko kugadzira kwegrey iron zvikamu ndezvayo zvehunyanzvi hunyanzvi. Iyo huruva ine mukurumbira wakashata - iyo yakanaka graphite nesimbi zvimedu - inoputika uye inosvika kwese. Iyo inoparadza madhairekitori emuchina uye bhora screws kana ikasagadziriswa zvine hukasha nekusefa kwakanaka uye kuiswa chisimbiso. Iwe haugone kushandisa nzira dzakafanana dzekutonhodza senge nesimbi; mafaindi anogona kuvhara masisitimu. Takadzidza izvi nenzira yakaoma pabasa repamusoro-soro rekugadzira dzimba dzepombi. Yedu yemazuva ese inonyungudika nemvura inotonhorera yakashanduka kuita slurry iyo yakaparadza zvivharo zvepombi muvhiki. Isu takachinjira kune imwe viscous, yekusefa-chaiyo inotonhorera uye kukwidza magadzirirwo ekugadzirisa.
Zvadaro pane tooling. Carbide inoiswa neyakapinza, yakanaka geometries inoshanda nemazvo, asi hupenyu hwematurusi hunogona kuve husingafungidzike kana ukarova jecha kusanganisirwa kana nzvimbo yakaoma kubva nekukurumidza kutonhora. Maturusi ePCD (polycrystalline diamond) akanakisa pakupedzisa mashandiro pasimbi yakachena, isingachinji, inopa hupenyu hunoshamisa, asi mutengo wepamberi wakakwira. Iko kuverenga: chikamu vhoriyamu, inodiwa kupera kwepamusoro, uye kushivirira. Nekuda kwepamusoro-chaiyo boring yezvigaro zvemuviri wevharuvhu, takatamira kuPCD uye hatina kumbotarisa kumashure-kuwirirana kwakazvibhadhara.
Ichi ndicho chikonzero mutengesi anobatanidza kukanda uye CNC machining pasi pedenga rimwe, sezvinoita QSY, ine mukana wakasiyana. Vanogona kuronga maitiro ekukanda vaine machining mupfungwa. Vanogona kuwedzera chidimbu chekuwedzera munzvimbo inononoka kupera, kana kuisa mutsara wekuparadzanisa kuti uderedze machining pane yakakosha datum. Iyi Dhizaini yeKugadzira Kufunga inobvisa yakawanda yemusoro inoitika kana kukanda uye machining kunoitwa nevakaparadzana, vakabviswa vatengesi.
Iyo Alloying Mubvunzo uye Surface Kurapwa
Plain grey iron (seASTM Kirasi 20, 30, 35) inovhara 80% yezvikumbiro. Asi dzimwe nguva unoda zvishoma. Kuwedzera chromium kunowedzera kuomarara uye kupfeka kuramba kwezvikamu zvakaita semadhiramu emabhureki kana silinda liner, asi zvinoitawo kuti simbi iwedzere brittle uye kuomesa muchina. Nickel yekuwedzera inobatsira kunatsiridza graphite uye kuvandudza kufanana uye simba, rinowanzoshandiswa muzvikamu zvakakora kudzivirira kupfava. Icho chiito chekuenzanisa.
Uye haungambo shandisa yakasvibirira, se-yakagadzirwa grey iron pamusoro mune ine simba application. Inoda kuchengetedzwa kana kuvandudzwa. Phosphating yakajairika yekudzivirira ngura uye sechigadziko chepende. Zvekutsvedza senge mhete dzepiston kana compressor plate, tin plating kana kuomesa induction zvinogona kutsanangurwa. Ndinorangarira chirongwa che hydraulic manifold blocks kwatakasvetuka kurapwa kwepamusoro kuti tichengetedze mutengo. Kukanganisa kukuru. Ngura diki yepasi yakaumbwa panguva yekutumira mhiri kwemakungwa, iyo yakazosvibisa iyo yese hydraulic system pakutanga. Mutengo wekukundikana wakawedzera mutengo weiyo nyore phosphating nhanho.
Kana Ikakundikana (Uye Sei)
Grey iron inokuudza kana isina mufaro. Kukundikana kwayo kunowanzova brittle uye pachena. Iyo yemhando yepamusoro grey iron ruzha - yakagomara thud pachinzvimbo chemhete kana yarohwa - ndeye kukurumidza kutarisa munda. Kutadza kwakawanda kwemumunda kwandakaongorora kunodzika kuzvinhu zvitatu: kushandisa tambo yekumanikidza kana kuvhunduka kwaisambofanirwa kubata (sekushandisa grey iron bracket sechibatiso), kuvhundutsa kwemafuta (kukurumidza, kupisa kusina kuenzana uye kutonhora kunokonzera kutsemuka), kana ngura kubva munzvimbo isina kukodzera.
Imwe nyaya yaisanganisira hombe, tsika gearbox dzimba. Yakakunda miedzo yose yedzvinyiriro asi yakakundikana mubasa pashure pemwedzi mitanhatu nokutsemuka kunotyisa. Ongororo yeMetallurgical yakaratidza kutsemuka kwakabva kune subsurface shrinkage cavity padyo nekona yemukati yakapinza-inosimudzira kushushikana. Iyo yekukanda pachayo yakasangana negiredhi spec, asi dhizaini (kona yakapinza) yakasanganiswa nediki, inotenderwa yekukanda kusakwana kwakagadzira iyo yekukundikana. Kugadzirisa kwaive kuri nyore asi kwakakosha dhizaini shanduko: kuwedzera fillet radius kune iyo kona mune iyo pateni, iyo yekutanga, QSY, aigona kugarisa nyore nyore. Yakasimbisa kuti kutsanangura zvinyorwa hakuna kukwana; iwe unofanirwa kugadzirira maitiro ekukanda.
Iyo Niche yeShell uye Investment Casting muIron
Mativi mazhinji esimbi egrey ijecha. Asi kune zvikamu zvinoda kupedzwa kwepamusoro, kusimba se-kukanda kushivirira, kana zvakanyanya kuomarara, matete geometries, mamwe maitiro anouya. Shell mold casting, iyo QSY inonyora seyakakosha, inoshandisa jecha-rakavharwa nejecha kugadzira mold yakaoma, yakatetepa-yakakomberedzwa. Inopa kupera kwakapfava uye kurongeka kwakaringana kupfuura jecha regirinhi rakajairwa. Funga nezvezvidiki, zvakaoma kunzwisisa injini zvikamu kana hydraulic valve miviri.
Investment casting yesimbi haina kuwanda nekuda kwemutengo, asi inoshandiswa kune zvakanyanya kuomarara, padyo-net-shape zvikamu uko machining angave akaoma zvakanyanya kana kuparadza. Detailed resolution haina kufananidzwa. Inyanzvi mukati mehunyanzvi, uye kuiona yakanyorwa nemutengesi inosaina danho repamusoro rekugona. Kune dzimba dzakaomesesa sensor dzimba dzine mapassage emukati, kushandura kubva kune yakagadzirwa simbi dhizaini kuenda kune yekudyara-yakakanda grey iron chikamu chakabatanidza akawanda mazvikamu, yakagadziridzwa damping, uye yakaderedzwa nguva yegungano, kunyangwe mutengo wepamusoro wekukanda.
Pfungwa dzekupedzisira: Kutsanangura neKungwara
Saka, paunenge uchitsanangura grey cast iron mechanical parts, fambisa kupfuura iyo ASTM kirasi chete. Funga nezvebasa: kunyorova, kumanikidza, kupfeka. Funga nezveketani yekugadzira: ichakandwa sei uye inogadzirwa sei? Taurirana nemutengesi wako nezvenzvimbo dzakakosha uye nzira dzekutakura. Mudiwa akanaka haangotauri zvakadhindwa; vanozobvunza mibvunzo nezve mashandisirwo uye vangangokurudzira yakapusa dhizaini tweak kana imwe nzira senge shell mold casting kuvandudza kuvimbika kana kuderedza mutengo wakakwana. Vavariro ndeyokuwedzera simba rezvakasikwa, kwete kurwisa kusasimba kwaro. Ndiwo mutsauko uripo pakati pechikamu chinongoshanda uye chinoshanda zvine hungwaru kwemakumi emakore.
