Anthu akamakamba za kupanga mchenga wa utomoni, nthawi zambiri amayerekezera mchitidwe wamba, pafupifupi wosakanizika—mchenga wongosakanizidwa ndi zomangira zothira patani. Ndiko kuphweka koopsa. Zoona zake ndi kuvina kosawerengeka pakati pa chemistry, nthawi, ndi kumva, pomwe kusiyana pakati pa kuyimba kwamawu ndi mulu wamtengo wapatali nthawi zambiri kumadalira pazambiri zomwe sanatchule. Sikuti amangopanga nkhungu; ndi za kulamulira zochita.
The Core Chemistry ndi Feel of the Sand
Mtima wake ndi binder system, nthawi zambiri furan kapena phenolic resin yokhala ndi chothandizira asidi. Ziwerengerozo si manambala a buku lamanja chabe; amasuntha ndi chinyezi, kutentha kwa mchenga, ngakhale mtundu wa utomoni. Mumaphunzira kuwerenga mchenga. Kusakaniza kuyenera kukhala ndi mawonekedwe ake pofinyidwa, koma kusweka bwino-osati kumata kwambiri, osagwedezeka kwambiri. Ngati mchenga ukumva kuzizira ndipo nthawi yovula ikhala yaulesi, mungafunike kuwongolera kuchuluka kwa othandizira, mwina ndi theka la peresenti. Ndi kuitana chiweruzo. Ndawonapo magulu akuwonongeka chifukwa wina adatsatira pepala lachidziwitso ku chilembo pa tsiku lachinyezi lachilimwe, kunyalanyaza kuti mulu wa mchenga pakhomo unali kuyamwa chinyezi.
Ndiye pali mchenga womwewo. Mchenga wa silika ndiwofala, koma pazinthu zina zomwe zimafuna kukhazikika kwamafuta kapena kutha kwa pamwamba, mutha kusamukira ku zircon kapena chromite. Kukula kwambewu ndi kagawidwe kake ndizofunikira kwambiri kuti zitheke. Mchenga wabwino kwambiri umatha kutsekereza mpweya, zomwe zimatsogolera ku nkhonya ndi mabowo. Tinaphunzira izi movutikira pa gulu la nyumba zapampu kwa kasitomala, pomwe kusintha kwa ogulitsa mchenga - zowoneka ngati zofanana - zidapangitsa kuti pakhale chiwopsezo cha 15% kuchokera ku zolakwika zapansi panthaka. Tsambalo linati AFS 55, koma mawonekedwe a tirigu anali osiyana, zomwe zimakhudza momwe mpweya unathawira.
Apa ndi pamene zochitika trumps chiphunzitso. Nthawi ya muller - nthawi yayitali bwanji mukasakaniza mchenga, utomoni, ndi chothandizira - ndiyofunikira. Osasakanikirana, mumapeza malo ofooka. Mukasakanikirana, mumayamba kuchiritsa msanga, ndikutaya moyo wa benchi. Mumakulitsa rhythm. Kwa kachitidwe ka furan, mwina ndi masekondi 90 pambuyo poti chothandizira chikupopera, koma mukuwona momwe mawonekedwe asinthira. Ndi njira yogwirika komanso yowoneka ngati yanthawi yake.
Kupanga Zitsanzo ndi Kukonzekera Kwambiri
Njira, kaya nkhuni, zitsulo, kapena pulasitiki, ndi pamene ndondomekoyi imayambira. Kulakwitsa kofala kwa oyambitsa ndikuchepetsa kulephera. Ngakhale kuti mchenga wa utomoni utasungunuka kwambiri poyerekeza ndi mchenga wobiriwira, pamafunika kuunika kokwanira kuti muvute bwino. Kwa ma geometri ovuta amkati, nthawi zina timagwiritsa ntchito magawo ambiri kapena zidutswa zotayirira. Ndikukumbukira njira yovuta ya gear pomwe tidaphonya poyambira pachimake. The nkhungu anavula, koma anang'amba, kusiya inclusions mchenga mu kuponyera. Kukonzanso pang'ono kwachitsanzocho, ndikuwonjezera madigiri 1.5 owonjezera, kunathetsa kwathunthu.
Mapeto a pamwamba pa chitsanzo amamasulira mwachindunji kuponya. Mtundu wopukutidwa wa epoxy umapereka malo osalala ngati oponyedwa kuposa matabwa omangika. Kwa maulendo apamwamba kwambiri, machitidwe achitsulo ndi omwe amapitako, koma kwa ma prototypes kapena maulendo afupiafupi, urethane wochuluka kwambiri kapena ngakhale matabwa olimba otsekedwa bwino amatha kugwira ntchito, malinga ngati mutavala. Chida cha chitsanzo ndi ndalama, ndipo khalidwe lake limasonyeza mphamvu ya nkhungu iliyonse yomwe ikutsatira.
Kutulutsa mpweya ndi nuance ina yokhudzana ndi mawonekedwe. Njirayi imafunika mazenera oikidwa bwino, nthawi zambiri mapini ang'onoang'ono kapena mawaya, kuti mpweya utuluke pamene mchenga ukuzungulira mozungulira. Ngati izi zatsekedwa kapena zosayikidwa bwino, mumapeza madera ofewa, osakanikirana bwino mu nkhungu, zomwe zimapangitsa kuti pakhale zotupa kapena kutayika panthawi yothira. Ndi tsatanetsatane yaying'ono yokhala ndi zotsatira zazikulu.
The Kuthira Njira ndi Solidification Control
Kuthira mu nkhungu yamchenga wa resin ndikosiyana ndi mchenga wobiriwira. Khungulo ndi lolimba komanso lochiritsidwa, kotero silikhala ndi nkhungu yobiriwira. Izi zikutanthawuza kuti muyenera kusamala kwambiri ndi gating ndi mapangidwe okwera kuti mupewe misozi yotentha kuti isapitirire. Nthawi zambiri timagwiritsa ntchito manja okwera okwera kuti zitsulo zokwera zisungunuke, ndikudyetsa bwino. Kuzizira kwa nkhungu kumasiyananso; Mchenga wa utomoni nthawi zambiri umakhala ndi matenthedwe otsika kuposa mchenga wobiriwira, womwe ungakhudze mawonekedwe olimba, nthawi zina kumabweretsa kumbewu zouma pang'ono ngati sizikuyendetsedwa.
Kuwongolera kutentha kwachitsulo ndikofunikira kwambiri. Kuthira kotentha kwambiri kungayambitse kukhudzidwa kwakukulu pa mawonekedwe a zitsulo zachitsulo, zomwe zimapangitsa kulowa ndi kuwotcha pamchenga wosanjikiza zomwe zimakhala zovuta kuyeretsa. Kuthira kozizira kwambiri kumawononga mitrus ndi kutsekeka kozizira. Pakuponyera zitsulo zapakatikati, titha kuyembekezera kutentha kothira mozungulira °C, koma kumasinthidwa kukhala makulidwe agawo. Bokosi lokhala ndi mipanda yopyapyala limafunikira kutentha kuposa chipika chokhuthala.
The shakeout ndi pamene ubwino wina wa utomoni mchenga kuwala. Pambuyo pozizira, nkhunguyo imaphwanyidwa chifukwa cha kutentha kwa resin binder. Ndikosavuta kugwira ntchito kwambiri kuposa kugwetsa nkhungu yolemera ya mchenga wobiriwira. Komabe, mchengawo tsopano wawonongeka chifukwa cha kutentha ndipo umakutidwa ndi dothi lakufa lochokera ku utomoni wowotchedwawo. Simungathe kuzigwiritsanso ntchito mwachindunji. Zimafunika kukonzanso - kuphwanya, kupukuta, ndi chithandizo cha kutentha - kuti abwezeretsedwe mu dongosolo, chomwe ndi chinthu china chonse chamtengo wapatali.
Kugwiritsa Ntchito Padziko Lonse ndi Kuganizira Zazinthu
Kuponya mchenga wa resin imapambana pomwe mukufunikira kulondola kwamlingo, kumaliza bwino kwapamwamba, komanso kuthekera kopanga mawonekedwe ovuta m'ma voliyumu otsika mpaka apakatikati. Ndiwofunika kwambiri pazoyambira zogwirira ntchito komanso zida zomwe ndizovuta kwambiri kapena zomwe zimafuna kulolerana bwino kuposa momwe mchenga wobiriwira ungapereke. Ganizirani za matupi a valve, ma pompa, zida zam'madzi, ndi zoyambira zamakina.
Mitundu yazinthu ndi yotakata. Tachita bwino ndi chitsulo cha ductile, iron imvi, carbon ndi low-alloy steels, komanso magiredi osapanga dzimbiri. Komabe, pazitsulo zokhala ndi aloyi wapamwamba kwambiri, zosapanga dzimbiri zosapanga dzimbiri, kapena zida zapadera za nickel ndi cobalt, muyenera kusamala kwambiri. Mpweya wa nkhungu ndi kuthekera kwa kujambula kwa carbon kuchokera ku binder kungakhale vuto. Nthawi zina ma binder system, ngati alkaline phenolic, amasankhidwa kuti ma alloys asungunuke achepetse kuipitsidwa pamwamba. Kampani yodziwa zambiri zakuthupi, monga Malingaliro a kampani Qingdao Qiangsenyuan Technology Co., Ltd., yomwe yakhala ikugwira ntchito ndi cobalt ndi nickel-based alloys kwa zaka zambiri, ingamvetse bwino izi mozama. Kuyang'ana kwawo kwanthawi yayitali pakupanga ndi kupanga mwaluso kumatanthawuza kuti atha kuyang'ananso zovuta zomwe zimakumana ndi nkhungu panjira zosiyanasiyana, kuyambira pakuwumba zipolopolo mpaka. utomoni mchenga kuponyera.
Ndikoyeneranso kuzindikira kuti panthawiyi utomoni mchenga kuponyera ndi zosunthika, sinthawi zonse njira yotsika mtengo pazigawo zazikulu, zosavuta. Mtengo wa ma binder ndi mtengo wokonzanso mchenga umatanthauza kuti mtengo wamchenga ndi wokwera kuposa mchenga wobiriwira. Chifukwa chake kugwiritsa ntchito kwake kumatsimikiziridwa ndi mtengo wowonjezedwa mwa kulondola komanso zovuta. Kwa chivundikiro chaching'ono chosavuta? Gwiritsani ntchito greensand. Kwa prototype ya block block yokhala ndi jekete zamadzi zovuta? Ndiko kumene mchenga wa utomoni umabwera mwawokha.
Maphunziro a Pansi ndi Integrated Manufacturing
Chimodzi mwa maphunziro akuluakulu ndikuti kuponya nthawi zambiri si gawo lomaliza. Momwe gawolo limatuluka mu nkhungu zimatengera mtengo ndi kuthekera kwa makina. Wopangidwa bwino utomoni mchenga kuponyera ndondomeko iyenera kukhala yofanana ndi net-shape, kuchepetsa makina opanga makina. Izi zimafuna mgwirizano wapakati pakati pa maziko ndi malo ogulitsira makina.
