Chifukwa chiyani 17-4PH Factory Partnerships Imalephera-Ndipo Momwe Gulu Limodzi la Qingdao Limayithetsera Tsiku ndi Tsiku
Mainjiniya ambiri omwe amapeza magawo a 17-4PH amagunda khoma lomwelo: wothandizira amalonjeza kulimba kwa H900 ndi kutsatira kwa ASTM A564, kenako amapereka kuuma kosagwirizana pamtanda-kapena moyipa kwambiri, ming'alu yaying'ono pambuyo pakutentha. Taziwona mu ma hydraulic valve housings okanidwa pakati pa msonkhano, mu manja a pampu ya pistoni akulephera ku 3,200 psi, muzitsulo za winch zikuwombera pomaliza. Choyambitsa chake sizinthu zopanda pake-ndi kuthekera kogawika. A zoona 17-4PH fakitale ayenera kulamulira zitsulo, Machining, ndi matenthedwe processing pansi pa denga limodzi. Osati kokha “wokhoza”—koma wotsimikizirika, wolondoleka, wobwerezabwereza.
Kuwongolera kwa Metallurgical Kumayambira Machining Asanayambe
17-4PH sikuti ndi "chitsulo chosapanga dzimbiri chokhala ndi mkuwa." Kukana kwake kwa dzimbiri ndi 1,100 MPa mphamvu zolimba zimadalira zenizeni za ukalamba: zazifupi kwambiri, ndipo ma precipitates sapanga; motalika kwambiri, ndipo amakwiyira, kulimba konyozeka. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., billet iliyonse ya 17-4PH imafika ndi malipoti athunthu a mayeso a mphero—otsimikiziridwa ku AMS 5604 kapena ASTM A564 Giredi 630—ndipo amatsimikiziranso: kuyezetsa spark, kusanthula kwa PMI, ndi kutsimikizira kutentha kwa chipangizo chilichonse chisanadulidwe.
Sitimapereka chithandizo cha kutentha kunja. Malo athu ogwirizana ndi ISO amayendetsa ng'anjo zoyendetsedwa mumlengalenga zokhala ndi ± 2 ° C zofanana, zotsatiridwa ndi kuzimitsa kwa helium kuletsa mapangidwe a delta ferrite. Kukalamba kumayikidwa pagawo lililonse - osati kusinthana - ndi mapu a nthawi yeniyeni ya thermocouple. Zotsatira zake? Kusintha kwa kuuma kumakhala mkati mwa HRC 38-40 pa chikhalidwe cha H900, kutsimikiziridwa pa mfundo zitatu pa gawo lililonse pogwiritsa ntchito masikelo a Rockwell B ndi C. Palibe zongoyerekeza. Palibe kukonzanso.
Makina Olondola Omwe Amalemekeza Njere
17-4PH imagwira ntchito molimba mtima. Njira zopangira zida zokhazikika zimapangitsa kuti m'mbali mwake muvale mwachangu, macheza amanjenjemera, komanso kugwedezeka pang'ono, makamaka m'nyumba zokhala ndi mipanda yopyapyala kapena ma valve opindika ozama. Gulu lathu la CNC limagwiritsa ntchito njira zamphero zopatsa thanzi zokhala ndi zoyikapo za carbide zokutidwa ndi PVD, ma adaptive roughing omwe amachepetsa mphamvu ya radial ndi 35%, ndi zida zolimba zovotera 12,000 rpm spindles.
Timayika zinthu zofunika kwambiri * pambuyo * kukalamba - osati kale. Chifukwa chiyani? Chifukwa mpumulo wa kupsinjika pambuyo pa kutentha umasintha gawo la geometry. Kulekerera kwa 0.015 mm panyumba ya 200 mm m'mimba mwake sikutheka ngati mutakalamba ndikukalamba. Mayendedwe athu amatsekera zowongolera za GD&T mpaka kumapeto: kumaliza pamwamba Ra ≤ 0.8 μm pankhope zosindikiza, kulolerana kwamalo ± 0.02 mm pamabowo okwera, ndi kukhazikika kumasungidwa mpaka 0.01 mm pamabuku a shaft-zonse zimayezedwa pa Zeiss yokhazikika CONTURA G2 CMM yokhala ndi kutentha kokwanira.
Kumene Kuponya Kumakumana ndi Katswiri Wamphamvu Yamphamvu ya Aloyi
Ntchito zina za 17-4PH zimafuna zovuta zapafupi ndi ukonde zomwe sizingachitike ndi bar stock: maziko a pampu asymmetric, njira zoziziritsira zophatikizika m'mavavu ambiri, kapena midadada yama silinda ambiri. Ndipamene chitsanzo chathu cha mphamvu ziwiri chili chofunikira. Timaponyera 17-4PH kudzera popanga ndalama-osati mchenga-kuti tikwaniritse zovuta zapamtunda monga Ra 3.2 μm ndi kukhazikika kwapakati pa ± 0.3% ya kukula kwake.
Koma kuponyera 17-4PH kumabweretsa chiopsezo: kuchepa kwa porosity, kupatukana pazigawo zokhuthala, ndi kusungunula ngati kuzizira kumachokera ku 5-10 ° C / s. Gulu lathu lothandizira limayang'anira kulimba ndi kuyerekezera kwamafuta, kusintha mawonekedwe a gating pogwiritsa ntchito kayesedwe ka MAGMASOFT, ndikutsimikizira kutsanulira kulikonse ndi kuyesa kwa ultrasonic (ASTM E114) ndi kuyang'ana kwa macro-etch. Kuponyedwa kulikonse kumakhala ndi ID yapadera ya kutentha yolumikizidwa ndi lipoti lake lamankhwala, chipika chozungulira cha kutentha, ndi zotsatira za NDT - zotsatiridwa kwathunthu ku batch yamafuta.
Kutsimikizika Kwapadziko Lonse—Osati Kungotsatira Mapepala Okha
Kutsatira sikutanthauza kanthu popanda nkhani. Pamene European OEM ikufunika 17-4PH pisitoni pampu silinda nyumba za mapampu m'mphepete mwa nyanja, iwo anafotokoza ASTM A564, H900, ndi kukana kutsitsi mchere ≥1,000 maola ASTM B117. Koma sanatchule momwe angagwiritsire ntchito kusintha kwa 12-mm-thick flange-to-barrel-chodziwika bwino chowonjezera nkhawa.
Tidathamanga motengera kutopa motsogozedwa ndi FEA, ndikuwonjezera kuwombera komweko komwe kumayambira pa fillet radius, ndikutsimikizira moyo wokulirapo ndi kuyesa kwa 500,000-cycle hydraulic pulsation pa 4,500 psi. Zigawo zidadutsa. Chofunikira kwambiri, adatumiza munthawi yake - chifukwa makina athu owonda amatsata chithandizo cha kutentha, kukonza, ndikumaliza molingana, osati mndandanda. Nthawi yotsogolera ya prototype: masiku 18. Kuchuluka kwapakati (ma PC 500): masiku 32. Onse okhala ndi zolemba zonse za PPAP, kuphatikiza maphunziro a MSA ndi mapulani owongolera.
Ngati pulojekiti yanu yotsatira ya 17-4PH ikufuna kukhulupirika kwapang'onopang'ono, kukana kwa dzimbiri muzofalitsa zaukali, ndi kulekerera kwazinthu zodabwitsa zauthenga - yambani ndi mnzanu yemwe amawona sayansi ya alloy ngati yosakambitsirana, osati yosankha. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. zimagwira ntchito ngati zoona 17-4PH fakitale: zophatikizika molunjika, zowongolera mwazitsulo, komanso zopangidwira kudalirika kofunikira kwambiri. Mayendedwe awo samangokwaniritsa zofunikira - amayembekezera njira zolephera chida choyamba chisanakhudze chitsulo.
