Pamene pampu ya hydraulic ikulephera muzitsulo zamafuta za m'mphepete mwa nyanja-kapena valavu yopondereza imasweka panthawi yoyezetsa kwambiri-choyambitsa nthawi zambiri chimachokera ku chisankho chimodzi: kusankha zinthu. Fakitale yamakina a alloy-based alloy mechanical silemba laogulitsa. Ndichitsimikiziro chogwira ntchito pamakina omwe kugwedezeka kwamafuta, kuvala kwa abrasive, ndi katundu wokhazikika wa 20,000-psi amachotsa malire pakulakwitsa.
Chifukwa chiyani ma cobalt alloys amafunikira kupanga mwapadera - osati makina wamba
Ma cobalt-chromium superalloys monga AMS 5387 ndi T800 si "ovuta kupanga makina." Amakhala odana ndi zitsulo: amaumitsa ntchito mwachangu kuposa momwe chida chingadulire, kutenthetsa mokwanira kuti atseke kutentha pamawonekedwe, komanso kukhudzidwa pang'ono ndi kupsinjika kotsalira kapena kuzizira kosiyana. Tawonapo masitolo akuyesa ma nozzles a T800 pa mphero wamba wa CNC-kungochotsa 60% ya nkhani yoyamba kuchokera kung'anjo yaying'ono pakuwotcha komaliza. Kupambana kumafuna zambiri kuposa zoyika za carbide. Imafunikira njira zophatikizika zopangira makina opangira makina, kuwongolera mlengalenga kusanachitike, ndi njira zosinthira zotsogozedwa ndi CMM zomwe zimatsata kutembenuka kwanthawi yeniyeni munyumba zokhala ndi mipanda yopyapyala.
Ichi ndichifukwa chake mphamvu ya fakitale yochokera ku cobalt yochokera ku alloy imayambira kumtunda - pakutsata zinthu. Billet iliyonse ya AMS 5387 yomwe timapanga imakhala ndi malipoti athunthu a mayeso a mphero, ndikuwunika kowonekera kumatsimikiziridwa ndi ASTM E1099 ndi kukula kwambewu kumatsimikiziridwa pa ASTM E112. Palibe cholowa m'malo. Palibe zoloweza m'malo "giredi yofanana". Ngati chojambula chanu chikunena za AMS 5387, mumapeza AMS 5387-osati yofanana ndi 0.3% yochepa ya chromium komanso kuuma kwapang'onopang'ono.
Mphamvu zinayi zosakambidwa kumbuyo kwa magawo ofunikira a cobalt
Wokondedwa wodalirika ayenera kupereka kusasinthasintha-osati kamodzi kokha, koma kudutsa ma 500-mayunitsi opanga ndi ziyembekezo za moyo wa zaka 10. Izi ndi zomwe timatsimikizira tisanatchule:
- Kukhazikika kwapang'onopang'ono kudzera mu hybrid processing: Mchenga-cast cobalt alloy plugs amachepa mosadziwika bwino. Yankho lathu? Ma cores opangira ndalama okhala ndi malo osindikizira a CNC-okhala ndi ± 0.015 mm pa 120-mm ma diameter popanda kupotoza pambuyo-machining.
- Kukhazikika kwapamwamba pamwamba pa kumaliza pamwamba: Ra 0.4 µm sizitanthauza kanthu ngati kung'amba pang'ono kumapangitsa kutopa koyambirira. Timagwiritsa ntchito ma RPM otsika, omaliza chakudya chokwanira ndi zida zothandizidwa ndi cryogenically-ndikutsimikizira kukhulupirika kwa subsurface kudzera pazithunzi za SEM zapagawo zoyambira.
- Kutsimikizika kogwira ntchito kupitilira GD&T: Mphuno ya aloyi ya cobalt sivomerezedwa pambuyo pofufuza CMM. Imakhala ndi ma calibration oyenda pa 350 ° C, kuyezetsa kukokoloka ndi 80-grit silica slurry pa 12 m / s, ndikuwunika kwa akupanga kwa porosity yamkati pa ASTM E1961 Level 3.
- Kufufuza komwe kumapangitsa kusanthula kulephera: Gawo lirilonse limanyamula chiphaso cha QR-code cholumikizira nambala ya kutentha kwa zinthu, zipika za ng'anjo, masitampu oyendera, ndi ID ya opareshoni. Pamene kulephera kwa ntchito kukuchitika, mainjiniya samalingalira - amalekanitsa maziko mu maola, osati masabata.
Kumene ogulitsa ma generic akulephera - ndipo akatswiri amapereka
Opanga ena amawona ma aloyi a cobalt ngati "chitsulo china chachilendo." Amagwira mawu potengera kulemera, osati mbiri ya kutentha. Amatumiza kunja kwa omwe adayambitsa chipani chachitatu popanda chidziwitso cha cobalt - kenako amalimbana ndi mawonekedwe osagwirizana a dendritic. Amalumpha njira zochepetsera nkhawa asanapange makina omaliza, zomwe zimapangitsa kuti pakhale nkhondo m'nyumba za silinda zapampu ya piston pambuyo pomanga.
Tidakhala ndi makasitomala akusintha pulojekiti yapakatikati atazindikira kuti omwe adawagulitsa kale adagwiritsanso ntchito zidutswa za cobalt zomwe zili ndi mbiri zosatsimikizika. Zotsatira zake? Kuthamanga msanga mu winch center shaft rollers pansi pa cyclic torsional load. Kuyankha kwathu sikunangolowetsamo - kunali kuwunika kwazitsulo, kukonzanso nthawi zoziziritsa kutentha, ndikukonzanso njira zoperekera zoziziritsa kukhosi mu pulogalamu ya CNC. Ndiko kuphatikizika koyima: kuponyera, kukonza makina, chithandizo cha kutentha, ndi NDT pansi pa denga limodzi, ndi chidziwitso chogawana - osati ma handoffs.
Kusankha fakitale yanu yamakina opangidwa ndi cobalt: mafunso atatu omwe amalekanitsa anzawo ndi ogulitsa
Musanasaine NDA, funsani izi-osati mayankho otsatsa, koma umboni wolembedwa:
- "Ndiwonetseni maere anu atatu omaliza a AMS 5387 - ma cert amphero, zipika za kutentha, ndi malipoti omaliza a CMM." Kusasinthika kumawonetsa pamapepala, osati malonjezo.
- "Kodi kutalika kwanu kosagwirizana ndi ma shaft a T800 ku Ø45 mm ndi chiyani - ndipo mumawongolera bwanji kuwongoka mukatembenuka?" Malire adziko lapansi amawonetsa kukhwima kwa njira.
- "Ngati mapangidwe athu a pampu amafunikira khoma la 0.8-mm pafupi ndi ngodya ya 90 ° yamkati, kodi mumatani kuti mutsimikizire kukhulupirika kwanu m'derali?" Izi zimayesa ukatswiri woponya, osati luso la makina okha.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. imagwira ntchito ku Qingdao yovomerezeka ku ISO 9001:2015, yokhala ndi ma cell odzipereka a cobalt-alloy, m'nyumba ya optical emission spectrometry, ndi makina oyezera ogwirizana omwe amayendetsa pulogalamu ya PC-DMIS. Mbiri yake imaphatikizapo ma nozzles a cobalt aloyi pamapampu othamanga kwambiri, zigawo za pampu za AMS 5387 zomwe zimakwaniritsa zofunikira za API 6A, ndi zida za T800 zama module owongolera pansi pa nyanja. Kampaniyo imathandizira makasitomala am'mafakitale ku North America, Europe, ndi Southeast Asia - ikupereka ma prototypes m'masiku 12, madongosolo apakatikati m'masabata 6-8, ndikutsata kwathunthu kwazinthu komanso kutsata kwapang'onopang'ono komwe kumapangidwira gawo lililonse.
Tsogolo la fakitale yopangidwa ndi alloy-based alloy mechanical parts sikhala mumakina akuluakulu-koma pakuphatikizana kolimba pakati pazitsulo, machining physics, ndi kutsimikizira magwiridwe antchito. Pamene zovuta zamakina zimakwera komanso nthawi zantchito zikukulirakulira, kusiyana pakati pa zovomerezeka ndi zofunikira kwambiri sikungayesedwe mu ma microns. Idzayesedwa mu nthawi yowonjezereka, malire a chitetezo, ndi mtengo wonse wa umwini. Sankhani moyenerera.
