Tinene zoona, anthu ambiri akamva 'mvula ikuuma chitsulo chosapanga dzimbiri', amaganiza za ngwazi ya data - 17-4PH, mwina 15-5PH, yokhala ndi ziwerengero zamphamvu zokolola. Zowona pamtunda wa sitolo, makamaka m'magulu ovuta komanso opangidwa ndi makina, ndi chilombo chosiyana. Sizongokhudza kugunda nambala yowuma; ndizoyang'anira kuvina pakati pa chithandizo chamankhwala, kukalamba, ndi kupotoza kosapeŵeka komwe kumabwera ndi izo, pamene mbaliyo nthawi zambiri imakhala yovuta, yochepetsetsa yopangira ndalama. Ndiko kumene chidziwitso chenicheni, ndi mbuna wamba, zimakhala.
Kukopa ndi Zowona za Maphunziro a PH
Timapeza mafunso ambiri a 17-4PH. Ndiko kupita. Makasitomala amawona kukhazikika kwa 1300 MPa ndikuganiza kuti ndikusintha komwe kumafunikira mphamvu zambiri. Koma ine ndawonapo mapulojekiti akupunthwa kunja kwa chipata chifukwa iwo sanaganizire chikhalidwe. Kodi tikuyamba ndi bar stock, forging, kapena casting? Kwa kampani ngati yathu, Malingaliro a kampani Qingdao Qiangsenyuan Technology Co., Ltd.,ku kuponya ndalama ndi njira yoyambira, nkhaniyo imayamba ndi chemistry yosungunuka ndi momwe zimakhalira. The homogeneity wa yankho annealed boma tisanaganize n'komwe za ukalamba n'kofunika. Kuponya kumatha kukhala ndi tsankho laling'ono lomwe bar yopangidwayo ilibe, zomwe zingayambitse kuyankha kosagwirizana pambuyo pake.
Ndiye pali ndondomeko ya makina. Kodi mumayika makina omwe ali ndi yankho (ofewa, osavuta pazida) ndiyeno kukalamba? Kapena mumakalamba kaye kenako ndikuyesa kupanga makina a 40+ HRC? Zakale nthawi zambiri zimakhala zanzeru, koma muyenera kusuntha kuchokera ku ukalamba kupita ku kulolera kwanu. Tinaphunzira izi movutirapo ndi thupi la valve. Anachipanga bwino mu Condition A, atachikalamba, ndipo adapeza kuti ma diameter ovuta anali olimba kuposa momwe amafotokozera. Anayenera kukonzanso kukonza zonse ndikukonzanso makina, lomwe ndi phunziro lokwera mtengo pakuyendetsa njinga zamoto.
Zimakukakamizani kuganiza mwathunthu. Kusankha sikungokhala chitsulo chosapanga dzimbiri, ndi unyolo wazinthu: kuponya kukhulupirika -> njira yofananira ya anneal -> pre-machining stock allowance -> kukalamba kolamulidwa -> kumaliza komaliza. Kusowa ulalo kumadula unyolo. Ichi ndichifukwa chake pamagawo odalirika kwambiri, nthawi zambiri timagwirizana ndi gulu laukadaulo la kasitomala kuchokera pagawo la CAD, osati RFQ ikafika.
Chikhalidwe H900 vs. H1150: Sikuti Ndi Kutentha Kokha
Zolemba za ukalamba (H900, H1025, H1150) ndizoyambira, osati uthenga wabwino. H900 imakupatsani mphamvu zapamwamba koma kulimba kocheperako. Pagawo la zida zofikira zomwe tidagwirapo, zomwe zidayitanitsa H900. Koma panthawi ya prototyping, mayeso a Charpy pa kutentha kochepa anali m'malire. Tinakambirana kwanthawi yayitali ndi metallurgist wa kasitomala. Kodi tingakwanitse kuviika kwamphamvu pang'ono kuti pakhale kulimba kwapang'onopang'ono? Tidathamanga gulu ku H925 kenako H950, kuyesa kulimba komanso mphamvu. H950 inatipatsa malire oyenera - mphamvu inali idakali pamwamba pa kapangidwe kake, koma zotsatira zake zidalumpha. Adavomerezedwa ngati njira ina yokalamba. Tsambalo silinatiuze zimenezo; kuyezetsa koyendetsedwa ndi chigamulo chaumisiri chidachita.
Apa ndi pomwe zaka 30-kuphatikiza pakuponya ndi CNC makina amalipira. Mumayamba kumva mmene zinthu zimayendera. Kuchuluka kwamvula aloyi, pa ukalamba, musamangokhalira kulimba; amasintha mobisika. Kwa nyumba yovuta, yosasinthika, iyi si yunifolomu. Tayamba kugwiritsa ntchito makuponi oyeserera ansembe omwe amapangidwa kuchokera kutsanulira komweko, wolumikizidwa kumadera ovuta a gawolo kudzera pazipata zopyapyala. Timakalamba msonkhano wonse, kenaka timadula makuponi kuti tiyese kuuma ndi kuwunika. Ndi sitepe yowonjezereka, koma imayang'ana kuyankha kwaukalamba kudera lonse la geometry, kupulumutsa chisoni pambuyo pake.
Ndipo tiyeni tikambirane za ntchito kachiwiri. Nanga bwanji ngati mbali ina yakalamba ndiye ikufunika kukonzedwanso? Ndi maloto owopsa. Kutentha kochokera ku kuwotcherera kumapitilira zaka za HAZ, ndikupanga malo ofewa. Nthawi zambiri mumayenera kubwereranso ku anneal yankho lathunthu, lomwe limatha kupotoza gawolo, ndikukonzanso makina ndikukalambanso. Nthawi zina, ndizovuta kwambiri kuzitaya. Iyi ndi mfundo yofunika kwambiri yomwe timatsindika pakuwunika kwa mapangidwe Mtengo wa QSY: ngati weldability ndi kuthekera mtsogolo, mwina kalasi yosiyana chitsulo chosapanga dzimbiri ndi bwino, ngakhale mphamvu yoyamba ndi yochepa. Mtengo wa moyo wonse ndiwofunika.
Kuphatikizika Kwapadera kwa Aloyi: PH motsutsana ndi Maraging
Ichi ndi tangent chidwi. Timagwiranso ntchito ndi ma aloyi apadera ngati zitsulo zowononga. Makasitomala nthawi zina amawasokoneza ndi PH zosapanga dzimbiri. Zonsezi zimalimbitsa ndi mvula, koma zitsulo zokhala ndi chitsulo-nickel ndi cobalt, molybdenum, titaniyamu - palibe chromium yolimbana ndi dzimbiri. Iwo ndi nyama yosiyana. Njira yothetsera vutoli ndi yosavuta austenitize ndi mpweya wozizira, kupanga martensite yofewa. Kukalamba ndiye kumayambitsa ma intermetallics. Kupotozako nthawi zambiri kumakhala kotsika poyerekeza ndi PH zosapanga dzimbiri, zomwe ndi mwayi waukulu pazinthu zazitali, zowonda zamakina.
Ndikukumbukira pulojekiti yopangira shaft yolondola kwambiri. Kupita koyamba kunali ndi 15-5PH. Pambuyo pa ukalamba, kuwongoka kunali kunja. Tinawongolanso ndi makina osindikizira olondola, koma si abwino. Tinapanganso chitsulo cha C250 ngati njira ina. Kukana dzimbiri sikunali kofunikira (kunali pamalo osindikizidwa, opaka mafuta). Njira yodutsamo inatipatsa mphamvu, chithandizo chosavuta cha kutentha popanda kusokoneza pang'ono, ndi makina abwino kwambiri mumkhalidwe wowonjezereka. Zinali zokwanira bwino. Ndi za kukhala ndi phale zakuthupi ndi chidziwitso chodziwa nthawi yotuluka kunja kwa bokosi losapanga dzimbiri.
Kuphatikizika kwa chidziwitso chotere ndikofunikira. Kugwira ntchito ndi zitsulo zopangidwa ndi nickel ndi ma aloyi a cobalt amakuphunzitsani zambiri za mpweya wa kinetics komanso kukhudzidwa kwa kutentha. Chidziwitso chimenecho chimabwereranso m'mene timachitira ndi ma PH omwe amapezeka kwambiri. Zonse zolumikizidwa.
CNC Machining: The Tooling and Coolant Dance
Machining PH opanda banga, makamaka okalamba, ndipamene mumawotcha pogwiritsa ntchito zida ngati simusamala. Ndi abrasive ndi ntchito-umauma. Takhazikika pamalamulo angapo ovuta. Choyamba, zokhazikika zokhazikika. Kulankhula kulikonse kudzagwira ntchito nthawi yomweyo-kuyimitsa pamwamba, ndikupanga gehena yotsatira. Chachiwiri, zoyika za ceramic kapena zapamwamba za carbide zokhala ndi mawonekedwe akuthwa, abwino. Sitikuyendetsa zitsulo zothamanga kwambiri kuno. Zoziziritsa kuziziritsa sizingakambirane, ndipo ziyenera kukhala zokometsera kwambiri, zopangira, zosefukira mowolowa manja. Cholinga chake ndikutulutsa kutentha ndi chip, osalola kuti chilowerere m'gawolo ndikutha kukulitsa ukalamba.
Kuboola maenje akuya ndizovuta kwambiri. Kubowola Peck ndikofunikira, ndikubweza kwathunthu kuti muchotse tchipisi ndikuziziritsa zitoliro. Tidaononga zopangira zodula pang'ono poyambirira polola tchipisi kuti tiyike ndulu ndikuwotchera pobowola, kenako ndikubowola. Tsopano, mapulogalamu athu a CNC azinthu izi ali ndi matebulo odyetsa / othamanga kwambiri, omangidwa kuchokera zaka zakuyesa ndi zolakwika. Zomwe zili patsamba lawo, https://www.tsingtaocnc.com, imakamba za kuthekera, koma kuthekera kwenikweni ndi laibulale ya parameter mu owongolera makina athu komanso zomwe okonza mapulogalamu athu amadziwa nthawi yoti asinthe.
Kumaliza kwa pamwamba kumafunikanso. Malo opangidwa movutikira pa aloyi ya PH amatha kukhala malo oyambira kupsinjika komanso kuyambitsa dzimbiri. Nthawi zambiri timatchula chiphaso chomaliza chokhala ndi choyikapo chomaliza kapena ngakhale kupukuta / kupukuta pang'ono pamalo osindikizira. Imawonjezera mtengo, koma kwa gawo la malo owononga, opsinjika kwambiri, ndi inshuwaransi.
Kuyang'ana M'mbuyo ndi Kupita Patsogolo
Ndiye izi zikutisiya kuti mpweya kuumitsa chitsulo chosapanga dzimbiri? Ndi banja labwino kwambiri lazinthu, koma limafunikira ulemu ndi njira yoyendetsera. Si katundu. Mtengo womwe wogulitsa amabweretsa sikungosungunuka ndi kuthira kapena kuyendetsa makina a CNC; ndikuphatikiza masitepe amenewo ndi zitsulo.
Pa Mtengo wa QSY, zaka makumi atatu zapitazo chipolopolo nkhungu kuponyera, kuyika ndalama, ndi kukonza makina kumatanthauza kuti takhala tikuwonapo mavutowa. Tapotoza ziwalo, zida zosweka, ndikutumiza makuponi oyesa kuti ukalamba ukhale bwino. Kukumbukira kwachikhazikitso ndiko kumalepheretsa kuti nkhanizo zisabwerenso pa ntchito yotsatira. Zimatilola kuwongolera makasitomala kutali ndi misampha yomwe ingakhalepo - monga kufotokozera ukalamba wa H900 pakuponyera kwakukulu, kocheperako komwe kungasokoneze mosasunthika, kapena kukonzekera sitepe yowotcherera pambuyo pochiritsa kutentha komaliza.
Tsogolo, ndikuganiza, likuphatikizana kwambiri. Mwina kugwiritsa ntchito kayeseleledwe kulosera kusokonekera kwa ukalamba kutengera kuyika kwa geometry, kapena kugwiritsa ntchito kuwunika kochulukira mkati mkati mwa makina kuti muzindikire kutayika kwa zida zisanachitike. Koma pachimake chikhalabe: kumvetsetsa kuti PH zosapanga dzimbiri ndi njira, osati zinthu chabe. Simukugula chipilala chachitsulo; mukugula kuchita bwino kwa matenthedwe ndi makina amakanika. Ndipo kulondola ndondomekoyi ndizomwe zimalekanitsa gawo logwira ntchito ndi lodalirika.
