Anthu ambiri akamva mawu oti “mchenga,” amayerekezera sitolo yauve, yachipwirikiti ikutsanulira zitsulo zofunika kwambiri. Ndilo lingaliro lolakwika loyamba. Zowona, makamaka pamalo omwe ali ndi mizu yakuzama yamafakitale ngati Qingdao, ndi magawo ang'onoang'ono. Sikuti amangopanga nkhungu kuchokera ku mchenga; ndi za kuwongolera zinthu zomwe siziziwona konse—chinyontho chamumchenga, kamangidwe ka zitseko, kulimba kwamphamvu. Ndawona mapulojekiti ambiri akulephera chifukwa wina adatenga kuponya mchenga ngati njira yosavuta yosunga zobwezeretsera. Ndi chilichonse koma.
The Core: Zonse Ndi Zamchenga (Ndipo Si Mchenga Wokha)
Tiyeni tiwongolere izi. 'Mchenga' ndi wosakaniza-mchenga wa silika, dongo (bentonite), madzi, ndipo nthawi zambiri zowonjezera monga fumbi la malasha kapena nyanja. Chiŵerengero ndi chirichonse. Chinyezi chochuluka, ndipo mumawombera nthunzi, ndikusiya mabowo akuponya. Chochepa kwambiri, ndipo nkhungu ilibe mphamvu zobiriwira, kugwa panthawi yothira. Ndikukumbukira gulu la mabakiteriya achitsulo omwe amangowonetsa nkhanambo. Tinafufuza zitsulo, kutentha, chirichonse. Zinapezeka kuti cholowera chamadzi chosakaniza mchenga chinali ndi mayendedwe pang'ono. Kusintha kwa 0.5% kwa chinyezi kunali kokwanira kuwononga kupanga kwa sabata. Ndiko kubisala mwatsatanetsatane munjira 'yosavuta'.
Ndiye pali nkhungu yokha. Pali mchenga wobiriwira, womwe umakhala wofala kwambiri, ndiyeno mchenga womangika ndi utomoni monga momwe zipolopolo zimapangidwira kapena makina ozizira. Malingaliro a kampani Qingdao Qiangsenyuan Technology Co., Ltd., mwachitsanzo, amandandalika kupanga nkhungu za zipolopolo ngati zapadera. Ndicho chirombo chosiyana. Amagwiritsa ntchito mchenga wokutidwa ndi utomoni kuti apange chipolopolo chopyapyala, cholimba mozungulira chotenthetsera. Kulondola kwa dimensional ndikwapamwamba kwambiri kuposa mchenga wobiriwira wamba. Kotero pamene mukuyang'ana pa luso la foundry, simungangowona 'kuponya mchenga.' Muyenera kufunsa: ndi njira yanji ya mchenga yomwe tikukamba?
Kupanga mafanizo ndi luso lina locheperapo. Mapangidwe a matabwa amazungulira. Mitundu yachitsulo ndi yokwera mtengo koma yomaliza. Pazigawo zovuta, mungafunike mawonekedwe amitundu yambiri okhala ndi ma cores. Kupanga chitsanzo sikungotengera gawolo; Muyenera kuwerengera kuchepera - kosiyana ndi chitsulo, chitsulo, kapena aluminiyamu - ndi ngodya zolembera kuti chithunzicho chikokedwe pamchenga bwino. Ndilo sitepe yoyamba yomwe mapangidwe apangidwe amatha kuchitika kapena kunyalanyazidwa, kuyika siteji ya kupambana konse kumtunda kapena kumutu kwa mutu.
Kumene Kuponya Mchenga Kuyenera (ndipo Kumene Kulibe)
Malo okoma a Sand casting amapangidwa kuchokera kumagulu apakati mpaka akulu. Ganizirani zanyumba zapampu, zoyambira zida zamakina, matupi a valve, zopanda kanthu zazikulu. Ndizosangalatsa pakupanga kusinthasintha ndikugwira ma aloyi osiyanasiyana, kuyambira zitsulo wamba mpaka ma aloyi apadera ngati opangidwa ndi faifi tambala. Webusayiti ya Mtengo wa QSY imatchula kugwira ntchito ndi ma aloyi apadera, zomwe zimakhala zomveka. Kuthira ma aloyi amtengo wapatali, ovuta kupanga mumchenga kungakhale kopanda ndalama zambiri kuposa kuyamba ndi billet yayikulu ndikuchotsa 80% yake.
Koma si za chirichonse. Ngati mukufuna zomaliza zosalala kwambiri kapena zololera zolimba kuposa, tinene, ± 0.5mm pamlingo wa 100mm, mukukankhira. Ndipamene njira monga kuponya ndalama (zomwe amachitanso) zimatengera. Ntchito ya postcast ndi yofunikanso. Chigawo chilichonse chimatuluka ndi kung'anima (chitsulo chochulukirapo pamizere ya nkhungu), sprues, ndi zipata zomangika. Ndiko kumene mbali ya Machining, ndi CNC makina Kuthekera koyambira kwantchito zonse monga QSY imapereka, kumakhala kosagwirizana ndi njira yoponya. Simungathe kupereka gawo lomalizidwa popanda icho.
Ndikukumbukira ntchito yopangira gawo la injini yapamadzi muzitsulo zosapanga dzimbiri. Ma geometry anali osavuta kuponya mchenga, koma mawonekedwe a dzimbiri anali ankhanza. Tinayenera kukhala osamala ndi zokutira nkhungu kuti tipewe kuchitapo kanthu kwa chitsulo ndi kuonetsetsa kuti pamwamba pa thunthu ndi kukhulupirika. Zinagwira ntchito, koma malire a zolakwika anali ochepa. Idatsimikizira kuti kusankha kwazinthu kumatengera magawo anu azinthu monga momwe mawonekedwe amachitira.
Mitu Yosapeŵeka: Porosity, Shrinkage, ndi Shakeout
Zolakwika. Nkhondo yatsiku ndi tsiku ya injiniya aliyense. Ndi kuponyedwa mchenga, kuphulika kwa gasi ndi ming'oma ya shrinkage ndizomwe zimakayikira nthawi zonse. Porosity nthawi zambiri imachokera ku nkhungu. Ngati mchengawo sunatuluke bwino kapena wonyowa kwambiri, mpweya wotsekeka umalowetsedwa muchitsulo pamene ukulimba. Mumapeza ma pinholes awa pakuyesa makina kapena kuyesa kukakamiza. Shrinkage ndi vuto la kutentha. Chitsulo chikazizira, chimalimba. Ngati simupanga zokwera (zodyetsa) moyenera kuti zipereke zitsulo zamadzimadzi kumalo olimba, mumapeza zotsalira zamkati. Kuyerekeza kwamakompyuta kumathandizira pano, koma palibe chomwe chingalowe m'malo mwazochitikira pakuyika kokwera.
Shakeout-kugogoda mchenga kuchoka pazitsulo zokhazikika-ndizothandiza kwambiri kuposa momwe zimamvekera. Chitani izi molawirira kwambiri, ndipo kuponyera kumatha kusokoneza kapena kusokoneza kupsinjika kotsalira. Chitani mochedwa kwambiri, ndipo mumalepheretsa kupanga. Mchengawo umafunika kuubweza, kuuzira, ndi kuukonza. Dongosolo lotentha, losagwira ntchito la mchenga lidzatsamwitsa ntchito yanu yonse. Ndakhala m'malo omwe kutentha kwapafupi pafupi ndi siteshoni ya shakeout kunali kosapiririka, komanso mtundu wa mchenga umakhala wovuta, zomwe zimapangitsa kuti pakhale zovuta zambiri.
Ndiye pali chipinda choyeretsera. Ndi ntchito yochuluka, yaphokoso, ndi fumbi. Kupukuta zitseko, kuwombera kuphulika kumalo oyera. Ndipamene kuponyera koyipa kumayamba kuwoneka ngati gawo. Zochita zokha zikuyenda pano, koma kwazinthu zambiri zopangira ntchito, iyi imakhalabe gawo lothandizira, lodalira luso. Ubwino wa kumaliza kwa manja komaliza ukhoza kupanga kapena kuswa mawonekedwe a gawolo ndipo nthawi zina ntchito yake.
Kuphatikiza ndi Machining: Ulalo Wosakambirana
Palibe zida zamakono zomwe zimapulumuka pakuponyedwa kokha. Pafupifupi gawo lililonse la mchenga limafunikira makina opangira zinthu pamalo ovuta - mabowo a bolt, nkhope zomata, mipando yokhala ndi mipando. Ichi ndi chifukwa chake chitsanzo cha ophatikizana poponyera mchenga maziko ndipo makina ogulitsa ndi amphamvu kwambiri. Pamene njira zonse zili pansi pa denga limodzi, ngati pa https://www.tsingtaocnc.com, kulankhulana kwachindunji. Gulu la makina amatha kuyankha ku maziko ngati apeza nthawi zonse mawanga olimba kapena kusuntha kwa porosity m'dera linalake la kuponyera, ndipo nkhungu kapena kutsanulira kungasinthidwe.
Ndawonapo njira ina: kuponyedwa komwe kumapangidwa mumzinda wina, kutumizidwa ku malo ogulitsira makina ena. Katswiri wamakina amamenya mchenga wolimba ndikuphwanya chida. Iwo amaimba mlandu mazikowo chifukwa cha 'zitsulo zonyansa.' The foundry amadzudzula chitsanzo kapena machining parameters. Masabata akuchedwa amachitika. Kupanga kophatikizana kumadutsa pamenepo. Wopanga mapulogalamu a CNC amathanso kunena kuti awonjezere milimita ya katundu pankhope yomwe imawonetsa kupotoza pang'ono, kuthetsa vutoli mwachangu.
Izi ndizofunikira pamindandanda yazinthu zomwe amatchula - chitsulo choponyedwa, chitsulo, chosapanga dzimbiri, cobalt ndi nickel alloys. Kupanga aloyi wopangidwa ndi faifi tambala ndi ntchito yapadera. Kukhala ndi ukadaulo wamakina m'nyumba kumatanthauza kuti oyambitsa amamvetsetsa kuthekera kwazomwe akutsanulira kuyambira tsiku loyamba. Atha kusankha kalasi yeniyeni ya aloyi yomwe imalinganiza katundu woponyera ndi zosowa pambuyo pokonza.
Bizinesi Yake: Kuposa Kusungunula Chitsulo
Kuthamanga pa foundry lero ndikuyenda pazingwe. Ndiwotsika mtengo kwambiri (ng'anjo, makina amchenga, kuwongolera kuipitsidwa), njala yamphamvu, ndipo imayang'anizana ndi chiwongola dzanja chosatha. Kuonjezera mtengo sikusungunula chitsulo; zili mu engineering. Phindu lake ndikuthandiza kasitomala kupanga gawo lomwe limapanga bwino, makina ochita bwino, komanso odalirika. Ndili pothetsa chithunzithunzi chachitsulo cha ntchito inayake.
Kampani yomwe yakhalapo kwa zaka zopitilira 30, ngati QSY, yawona zozungulira. Iwo asintha. Kupereka njira zingapo zopangira (mchenga, zipolopolo, ndalama) ndi makina amatanthawuza kuti atha kuwongolera kasitomala kunjira yotsika mtengo kwambiri yopangira, osati yomwe amachita. Ndicho chizindikiro cha opareshoni okhwima. Kutalika kwa moyo kumasonyeza kuti adutsa m'miyendo ya kusakaniza mchenga, zitsulo, ndi zitsulo zogulitsira nthawi yaitali kuti apange chidziwitso chenichenicho.
Chifukwa chake, mukawunika malo opangira mchenga, musamangopempha mtengo pa kilogalamu. Funsani za njira zawo zowongolera mchenga. Funsani momwe amapangira gating ndi kukwera kwawo. Funsani za luso lawo lakumanga m'nyumba ndi momwe amachitira mayankho pakati pa madipatimenti. Mayankho angakuuzeni zambiri za chiwopsezo chenicheni cha polojekiti yanu kuposa kabuku kowoneka bwino. Ntchitoyi ili mumitundu yoyendetsedwa, osati kungotsanulira.
