Mukamva 'AISI 8620 kuponya ndalama', lingaliro lachangu kwa ambiri ndilokhudza momwe amasungiramo magiya kapena ma shafts. Ndiko kulondola, koma ndipamenenso kuphweka kumayambira. Kunena zowona, kutchula 8620 pakupanga sikungoyika bokosi lazinthu pachojambula; ikudzipereka ku unyolo wa ndondomeko pomwe luso la foundry pakugwira ntchito yolimba yazitsulo zotsika zimakhala zovuta kwambiri monga momwe zimapangidwira. Ndawona mapangidwe ambiri akulephera osati chifukwa 8620 chinali chisankho cholakwika, koma chifukwa njira yoponyerayo sinagwirizane ndi mawonekedwe ake enieni, zomwe zimatsogolera ku kuuma kwamilandu kosagwirizana kapena kutsika kobisika. Izi sizinthu zongoyerekeza; ndizovuta kwambiri.
Chikhalidwe cha Aloyi ndi Kusokoneza Kutaya
AISI 8620 ndi chitsulo cha nickel-chromium-molybdenum, chotamandidwa chifukwa cha kulimba kwake komanso kuyankha kodalirika pakupanga carburizing. Komabe, machitidwe ake oponya ndi osiyana ndi mawonekedwe ake opangidwa. Chofunikira ndikuwongolera mpweya wa kaboni kuyambira pachiyambi. Popanga ndalama, kuzizira kofulumira kwa magawo oonda nthawi zina kumatha kupangitsa kuti pakhale mawonekedwe owoneka bwino kuposa momwe amayembekezeredwa, zomwe ndi zabwino, komanso zimawonjezera chiopsezo cha micro-porosity ngati njira yolowera ndi chakudya sichikukometsedwa panjira yolimba ya aloyiyi. Simungangogwiritsa ntchito mawonekedwe omwewo omwe mungagwiritse ntchito ngati chitsulo chosavuta cha kaboni.
Ndikukumbukira pulojekiti yomanga kachipangizo kakang'ono kamene kamafunikira kulimba mtima komanso kusagwira ntchito. Wofuna chithandizo anaumirira aisi 8620 kuponya ndalama. Magulu angapo oyamba adadutsa macheke koma adalephera kuyesa kukakamiza. Nkhani yake? Isolated micro-shrinkage. Sitinawerengere mokwanira momwe molybdenum mu 8620 imasinthira pang'ono zofunikira zodyetsa. Kukonzaku sikunangowonjezera zokwera, koma kuziyikanso kuti zikhazikike molunjika ku magawo ovuta. Chinali chikumbutso kuti pepala la alloy silimatchula umunthu wake.
Apa ndipamene kupeza kwanthawi yayitali kumapindulitsa. Kampani ngati Malingaliro a kampani Qingdao Qiangsenyuan Technology Co., Ltd., ndi zaka makumi atatu zachipolopolo ndi kupanga ndalama, zikanapanga laibulale ya deta yowona ngati imeneyi. Amadziwa, mwachitsanzo, kuti kwa 8620, kutentha kwa kuthirira kumafuna zenera lolimba kuposa zitsulo zina zotsika kwambiri kuti muchepetse kuchuluka kwa madzi ndi kukula kwambewu. Ndi chidziwitso chaching'ono ichi, chokhazikika chomwe chimalekanitsa kuponya kogwira ntchito ndi kudalirika kwambiri.
Kumene Njira Imapangira Kapena Kuphwanya Gawo
Kukopa kwa ndalama zopangira zinthu za 8620 ndizodziwikiratu: ma geometries ovuta, kumaliza kwabwino kwambiri, komanso mawonekedwe apafupi. Koma kupanga zipolopolo palokha kumalumikizana ndi alloy. Chigoba cha ceramic chiyenera kukhala ndi kutentha kwakukulu kuti zisagwirizane ndi manganese ndi chromium mu 8620 panthawi yothira, zomwe zingayambitse kuwonongeka. Chigoba chosawoneka bwino kapena kutentha kolakwika kusanayambike kutentha kumatha kuyambitsa carburization kapena decarburization ngakhale gawolo lisanalowe m'ng'anjo yotentha, ndikutaya kuwerengera konseko.
Pambuyo poponya, njirayo ndi yofanana. Kuchepetsa kupsinjika ndikovuta kukambitsirana musanapange makina, makamaka magawo omwe ali ndi magawo osiyanasiyana. Ndidalakwitsa kuyidumpha kamodzi pagulu la zida zolumikizirana, poganiza kuti kupsinjika kunali kocheperako. Zotsatira zake zinali zokhotakhota pamakina ovuta omwe adataya theka la batchi. Mtengo wa njira yochepetsera nkhawa imeneyo ndi wotsika kwambiri poyerekeza ndi mtengo wa zidutswa zamakina.
Kenako pamabwera chithandizo cha kutentha. Mchitidwe wokhazikika ndi carburizing ndi kuzimitsa. Koma khalidwe loyamba la kuponyera limalamulira chilichonse. Ngati pali tsankho lililonse la dendritic kapena magulu ang'onoang'ono ophatikizika kuchokera pakuponyedwa, kuzimitsa kumatha kuwakokomeza, zomwe zimapangitsa kuuma kosagwirizana kapena kuzimitsa kusweka. Wothandizira wabwino samangopereka nyimbo; adzapereka ndondomeko yovomerezeka yochizira kutentha kutengera momwe akuponyera. Kuchokera ku mafotokozedwe a QSY ogwirira ntchito ndi ma alloys apadera, njira yophatikizirayi yokhudzana ndi zinthu ndi ndondomekoyi ndi gawo loyenera la ntchito yawo, yomwe ndi yofunikira pa zinthu monga 8620 kumene zinthu zomaliza zimapangidwira.
CNC Machining: The Critical Finish
Apa ndi pamene 'ndalama' imapinduladi. Gawo lopangidwa bwino la 8620 liyenera kukhala ndi ndalama zochepa, koma katunduyo ayenera kukhala wofanana. Kuthekera kwa as-cast 8620 ndikosiyana ndi mnzake wopangidwa ndi annealed. Khungu lotayidwa ndilolimba ndipo limatha kukhala lopweteka pazida. Njira yolimba imagwiritsa ntchito mabala ofewa kuti adutse pakhungu asanayambe kupanga makina olemera. Kuyesera kupulumutsa nthawi pogwiritsa ntchito zida zogwiritsidwa ntchito nthawi zambiri kumapangitsa kuti zida zizikhala zofulumizitsa komanso kusakhulupirika kwapamwamba pamaso omaliza.
Kwa chigawo ngati chonyamulira mapulaneti, magazini okhala ndi ma splines amapangidwa pambuyo poponya. Kugwirizana kwa kuuma kwa kuponyera ndi kusakhalapo kwa voids mkati ndizofunikira kwambiri. Ngati kuponyera kumayambitsa porosity pang'ono pansi pamadzi, makina opangira makina amatha kutsegula, ndikupanga kukana. Ichi ndichifukwa chake kuwongolera njira mu gawo la foundry ndikuyika ndalama pakukolola zokolola. Wothandizira omwe amapereka Integrated kuponya ndalama ndi CNC makina, monga QSY, ili ndi ndondomeko yachindunji. Gulu lawo lopanga makina litha kuwonetsa vuto lomwe limachitika kaŵirikaŵiri ku gulu lawo loyambitsa makina, zomwe zingathandize kukonza zoyambitsa kuti makina akunja angonena kuti ndi 'gulu loyipa'.
Synergy ndiye chinsinsi. Atha kukonzekera komwe kuyambikako ndi malo a zipata poganizira za makina omaliza, nthawi zina ngakhale kuyika zida zoyambira. Kulumikizana kumeneku kumachepetsa nthawi yonse yopangira komanso mtengo wake, ndikupangitsa kuponya kosaphika kukhala gawo lomalizidwa, lolondola kwambiri.
Zogwiritsa Ntchito Padziko Lonse ndi Zolakwika
8620 zowonetsera ndalama zimawala muzofunsira zomwe zimafuna maziko olimba komanso olimba, osagwira ntchito. Ganizirani za ma hydraulic valve matupi, pomwe madoko amkati amafunikira malo olimba kuti asakokoloke chifukwa cha kutuluka kwamadzi, koma thupi limafunikira mphamvu kuti lithane ndi kupanikizika. Kapena zida zina zomwe sizikhala ndi maginito zomwe zimakhala zabwino. Komabe, sibwino kusankha ntchito yotentha kwambiri kapena malo owononga kwambiri - ndipamene ma alloys opangidwa ndi faifi tambala kapena cobalt amabwera, madera a QSY's material portfolio nawonso.
Cholakwika chofala ndikuchigwiritsa ntchito ngati kuli kofunika kuumitsa. 8620 kwenikweni ndi chitsulo chowumitsa milandu. Ndawona mapangidwe akuyitanitsa 8620 kuti iwumitsidwe mpaka 40 HRC. Zitha kuchitika, koma simukugwiritsa ntchito mwayi wake woyamba, ndipo mutha kutumikiridwa bwino ndi 4140 kapena 4340 giredi yomwe idapangidwira izi. Chisankhocho chiyenera kuyendetsedwa ndi ntchito, osati kungodziwa.
Kuwerengera kwachuma kumakhudzanso. Kwa mawonekedwe osavuta, okulirapo, kupanga kapena kupanga makina a bar stock kungakhale kotchipa. Mtengo wa aisi 8620 kuponya ndalama imatsegulidwa ndi zovuta, ma geometries a 3D omwe angafune makina ochulukirapo kapena kusonkhana kwa magawo angapo. Kutsika mtengo kwa makina opangira phula kumatheka chifukwa cha kuchepa kwa makina otsika ndi ntchito zomanga.
Navigating Supplier Selection
Kusankha wogulitsa pakupanga ndalama za 8620 sikungotengera mtengo wamtengo wapatali. Ndi luso lofufuza. Muyenera kufunsa za zomwe adakumana nazo ndi zitsulo zotsika aloyi: Kodi mulingo wawo wophatikizika ndi wotani? Kodi amapanga bwanji mageti a aloyiwa? Kodi angapereke malipoti azitsulo kuphatikizapo kukula kwa tirigu ndi kuyesa kwa gulu lolimba? Kufunitsitsa kwa ogulitsa kukambirana izi ndi chizindikiro chabwino cha kuya kwake.
Kutalika kwamakampani pantchitoyo, monga mbiri ya zaka 30 za QSY, nthawi zambiri zimagwirizana ndi chidziwitso chopeza kuthetsa mavuto. Ayenera kuti adakumanapo - ndikuthetsa - zovuta za mpweya wa gasi m'magawo okhuthala kapena kumaliza bwino pamagawo ovuta. Izi zimamasulira ku zodabwitsa zochepa panthawi yopanga.
Pomaliza, fufuzani kuphatikiza. Wokondedwa wabwino amayendetsa ulendo kuchokera ku chitsulo chosungunuka kupita ku gawo lomaliza. Izi zimatsimikizira kuyankha. Ngati vuto la chithandizo cha kutentha libuka, palibe zomveka bwino ngati zinali zoponyera kapena kutentha. Pakuti zigawo zikuluzikulu, izi mopanda malire kulamulira kuchokera chipolopolo nkhungu kuponyera mpaka Machining komaliza si mwanaalirenji; ndikofunikira kuti mukwaniritse magwiridwe antchito omwe AISI 8620 amatha kupereka.
