Apo vanhu vanotaura nezvekukandwa kwejecha resin, vanowanzofananidza nzira iri nyore, inenge isina kuchena-jecha rakasanganiswa nebhainda rakadirwa patani. Ndiko kuwedzeredza kune ngozi. Chokwadi ndechekutamba kwakashata pakati pemakemikari, nguva, uye kunzwa, uko musiyano uripo pakati pekukanda ruzha uye murwi wezvimedu zvinodhura unowanzoenderana nezvakawanda zvisingataurwe nemapepa. Hazvisi zvekungogadzira mold; ndezvekudzora maitiro.
Iyo Core Chemistry uye Kunzwa kwejecha
Mwoyo wayo ndiyo binder system, kazhinji furan kana phenolic resin ine acid inokonzeresa. Reshiyo hadzisi nhamba dzinobva mubhuku; vanochinja nehunyoro, tembiricha yejecha, kunyangwe mhando yeresin. Iwe dzidza kuverenga jecha. Iko kusanganiswa kunofanira kubata chimiro chayo kana yakasvinwa, asi kuputsa zvakachena-kwete kunyanya kunamatira, kwete kunyanya friable. Kana jecha richinzwa kutonhora uye nguva yekubvisa iri dofo, ungangoda kugadzirisa chikamu checatalyst, pamwe nehafu muzana. Kudanwa kwekutongwa. Ndakaona mabheti aparadzwa nekuti mumwe munhu akatevera pepa re data kune tsamba pazuva rezhizha rakanyorova, achiregeredza chokwadi chekuti murwi wejecha pamusuwo waitora unyoro.
Ipapo kune jecha pacharo. Silica jecha rakajairika, asi kune mamwe maapplication anoda kugadzikana kwekupisa kana kupera kwepamusoro, unogona kuenda kune zircon kana chromite. Saizi yezviyo uye kugovaniswa kwakakosha zvakanyanya kuti ipere. Jecha rakanyanya-rakanaka rinogona kubata magasi, zvichitungamira kukuputika nemapinho. Isu takadzidza izvi nenzira yakaoma pane batch yepombi dzimba dzemutengi, uko shanduko yemutengesi wejecha - inoita seyakafanana dhizaini - yakatungamira kune 15% chirahwe mwero kubva pasi pehurema. Iyo spec sheet yakati AFS 55, asi chimiro chezviyo chakange chakasiyana, chinokanganisa kuti magasi akapukunyuka sei.
Apa ndipo pane chiitiko trumps theory. Iyo muller nguva-inguva yakadii yaunosanganisa jecha, resin, uye catalyst-yakakosha. Zvisina kusanganiswa, unowana nzvimbo dzisina simba. Kuwedzeredza, unotanga maitiro ekurapa nguva isati yakwana, uchirasikirwa nehupenyu hwebhenji. Unovandudza rhythm. Kune furan system, pamwe ingangoita 90 masekonzi mushure meiyo catalyst yakapfapfaidza mukati, asi iwe uri kuona shanduko yekuchinja. Iyo inobatika uye yekuona maitiro zvakanyanya seyenguva yakatarwa.
Kugadzira Peteni uye Iyo Yakakosha Draft
Patani, ingava huni, simbi, kana plastiki, ndipo panotangira hurongwa. A common rookie error is underestimate draft. Kunyangwe nekuputsika kwakanyanya kwejecha resin kana ichienzaniswa nejecha rakasvibira, unoda dhizaini yakakwana yekubvisa yakachena. Kune yakaoma yemukati geometries, isu dzimwe nguva tinoshandisa akawanda-zvikamu mapatani kana zvidimbu zvakasununguka. Ini ndinoyeuka yakaoma giya kesi pateni apo isu takambopotsa undercut pane yakakosha kudhindwa. Iyo mold yakabviswa, asi yakabvaruka, ichisiya inclusions yejecha mukukanda. Kugadziridzwa kudiki kwepateni, ichiwedzera angori 1.5 madhigirii ekuwedzera dhizaini, yakagadzirisa zvachose.
Kupedzwa kwepamusoro pane pateni kunoshandura zvakananga kukanda. Iyo yakakwenenzverwa epoxy pateni inoburitsa yakatsetseka yakatsetseka se-yakandwa pamusoro pane yakakasharara yakagadzirwa nemapuranga. Pakumhanya kwepamusoro-vhoriyamu, mapatani esimbi ndiwo anoenda, asi kune prototypes kana mapfupi anomhanya, yakakwira-density urethane kana kunyange yakanyatsovharwa chisimbiso hardwood inogona kushanda, chero iwe uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge rakapfeka. Iyo patani midziyo ndeyekudyara, uye hunhu hwayo hunoraira kushanda kwega kwega mold inotevera.
Venting ndiyo imwe pateni-inoenderana nuance. Iyo pateni inoda mavhavha akaiswa zvine hungwaru, kazhinji mapini madiki kana waya, kuti mhepo ibude sezvo jecha rinotenderedzwa nekuripoteredza. Kana izvi zvakavharwa kana kuiswa zvisina kunaka, unowana nzvimbo dzakapfava, dzisina kuumbwa zvakanaka muforoma, izvo zvinotungamira mukuzvimba kuremara kana kunyange kubuda-kubuda panguva yekudira. Chinhu chidiki chine mhedzisiro yakakura.
Iyo yekudurura Maitiro uye Solidification Kudzora
Kudira mujecha resin mold kwakasiyana negreensand. Iyo mold yakaoma uye inorapwa, saka haina kupa kwegreensand mold. Izvi zvinoreva kuti iwe unofanirwa kuchenjerera negeti uye kusimuka dhizaini kuti udzivise misodzi inopisa kubva pakuvharirwa kukanganiswa. Isu tinowanzo shandisa exothermic simbi inosimudza maoko kuti simbi inosimudza pombi irambe yakanyunguduka kwenguva refu, tichipa kukanda zvakanaka. Iko kutonhora kwesimba re mold rakasiyanawo; jecha resin rinowanzo kuve nekushomeka kwekupisa kupfuura jecha rakasvibira, iro rinogona kukanganisa chimiro chekugadzika, dzimwe nguva chichitungamira kune zviyo zvakakora zvishoma kana zvikasagadziriswa.
Kudzora kwekushisa kwesimbi kwakakosha. Kudururira kupisa kwakanyanya kunogona kukonzera kuita kwakanyanyisa pane mold-metal interface, zvichitungamira kupinza uye yakatsva-pajecha layer iyo inotyisa kuchenesa. Kudurura zvinotonhorera zvakanyanya njodzi mistruns uye inotonhora inovhara. Kukandira simbi yepakati nepakati, tinogona kuvavarira tembiricha yekudururira kutenderedza °C, asi iyo inogadziridzwa kune ukobvu hwechikamu. Chibhuraketi chine madziro matete chinoda kupisa kudarika chivharo chakakora.
Iyo shakeout ndiyo imwe mukana wejecha resin inopenya. Mushure mekutonhodza, mold inodonha chaizvo nekuda kwekuparara kwekupisa kweiyo resin binder. Izvo zvakanyanya kushoma-kushanda zvakanyanya pane kugogodza kunze inorema greensand mold. Zvisinei, jecha racho zvino rasvibiswa nokupisa uye rakaputirwa nevhu rakafa kubva mutsvina yakatsva. Iwe haugone kungoishandisa zvakare zvakananga. Inoda kudzokororwa-kupwanya, kukweshwa, uye kurapwa kwekupisa-kuti idzoserwe muhurongwa, inova imwezve mutengo wekushanda.
Chaiyo-Nyika Zvishandiso uye Material Kufunga
Resin jecha kukanda inokunda paunoda kurongeka kwedimensional, yakanaka kupera kwepamusoro, uye kugona kuburitsa maumbirwo akaomarara mune yakaderera kusvika pakati mavhoriyamu. Icho chinhu chikuru chemabasa ekutanga uye ezvikamu zvakanyanya kuomesesa kana zvinoda kushivirira zviri nani pane zvakajairika greensand inogona kupa. Funga nezvemiviri yevharuvhu, pombi casings, marine hardware, uye mabhesi emuchina.
The material range yakafara. Takazviita zvinobudirira ne ductile iron, grey iron, carbon and low-alloy steels, uye kunyangwe mamwe mamakisi asina tsvina. Nekudaro, kune yakakwirira-alloy simbi, super duplex stainless, kana iwo akakosha nickel uye cobalt-based alloys, unofanirwa kungwarira. Iyo mold mamiriro uye mukana weiyo kabhoni pickup kubva kune binder inogona kuve nyaya. Dzimwe nguva imwe binder system, senge alkaline phenolic, inosarudzirwa aya alloys anoshandiswa kuderedza kusvibiswa kwepasi. Kambani ine ruzivo rwakadzama rwezvinhu, senge Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), iyo yakashanda necobalt uye nickel-based alloys kwemakore, yaizonzwisisa izvi zvinyengeri zvakanyanya. Kutarisisa kwavo kwenguva refu pakukandira uye kugadzira kunoreva kuti vangango fambisa matambudziko aya chaiwo ekubatana-mold mumaitiro avo akasiyana siyana, kubva pakuumbwa kwegoko kusvika. resin jecha kukanda.
Zvakakoshawo kucherechedza kuti nguva resin jecha kukanda inoshanda zvakasiyana-siyana, haisiriyo nguva dzose sarudzo yakachipa yezvikamu zvakakura, zviri nyore. Mari yebhainda uye mari yekudzorera jecha zvinoreva kuti mutengo wejecha wakakwira pane wegreensand. Saka kushandiswa kwayo kunoruramiswa nekukosha kwakawedzerwa kuburikidza nemazvo uye kuoma. Zvechivharo chemugodhi chiri nyore? Shandisa greensand. Yeinjini block prototype ine akaomarara emvura mabhachi? Ndiko uko jecha resin rinouya mune raro.
Zvidzidzo kubva Floor uye Integrated Manufacturing
Chimwe chezvidzidzo zvakakura ndechekuti kukanda hakuwanzo danho rekupedzisira. Kuti chikamu chinobuda sei mu mold chinoraira mutengo uye kugona kwekugadzira. Yakagadzirwa zvakanaka resin jecha kukanda process inofanirwa kunanga pedyo-net-shape, kuderedza machining stock. Izvi zvinoda kubatana kwepedyo pakati peiyo foundry nechitoro chemuchina. Mitsetse yekuparadzana isina kuiswa zvakanaka kana kusawirirana kwemadziro ukobvu kunogona kukonzera hope dzehusiku mukugadzirisa uye kupfeka kwemidziyo panguva yeCNC mashandiro.
Ichi ndicho chikonzero iyo modhi yemugadziri akabatanidzwa ane simba. Kambani inobata zvese kukanda uye kurongeka machining pasi pedenga rimwe, se QSY inoita, inogona kukwidziridza mafambiro ese ebasa. Chikwata chevakatanga chinoziva kugona uye zvipingaidzo zvemichina yeCNC kune rimwe divi remadziro, uye zvinopesana. Ivo vanogona kugadzira maitiro ekukanda-kusanganisira geting, kusimuka, uye musimboti kuiswa-vaine machinability mupfungwa. Ivo vanogona kuona kuti yakakosha datum nzvimbo dzakakandwa dzakachena uye dzakapfava zvakakwana kuti dzishandiswe kugadzirisa. Iyi synergy chimwe chinhu chinomira chakazvimirira kana shopu yemuchina inonetseka kutevedzera. Iwe unogona kudzidza zvakawanda nezve yavo yakabatanidzwa maitiro ekukanda uye kupedzisa pane yavo saiti pa https://www.tsingtaocnc.com.
Chekupedzisira, usaregeredza mamiriro ezvakatipoteredza nekuchengetedza. Furan resins inoburitsa formaldehyde panguva yekusanganisa nekudurura. Kufefetedza kwakaringana uye PPE hazvigone kutaurirana. Jecha rinoshandiswa, kana risina kudzorerwa, rinova nyaya yekurasa. Zvivako zvemazuva ano zviri kufamba zvichienda kune mamwe mabhainda masisitimu ane hushamwari, asi kazhinji anouya nekutengesa-mumutengo kana kuita. Icho chiitiko chenguva dzose chekuenzanisa pakati pezvinodiwa zvehunyanzvi, zvehupfumi, uye kutevedza kwemitemo.
Saka, paunotarisa a resin jecha kukanda, hausi kungotarisa simbi. Uri kutarisa mhedzisiro yemazana ezvisarudzo zvidiki — nezve chemistry, tembiricha, nguva, uye dhizaini. Kuigadzirisa kunonzwa kushoma sekutevera resipi uye zvakanyanya sekuridza orchestra uko chiridzwa chese chine hasha. Asi kana zvese zvauya pamwechete, iko kurongeka uye kuoma kwaunogona kuwana ndiko kunoita kuti iyi makumi emakore-ekare maitiro anyatsoenderana mukugadzira kwemazuva ano.
