Yese fekitori yekukanda simbi inotanga nemubvunzo mumwechete: Iwe unoshandura sei simbi yakanyungudutswa kuita chikamu chisingatsemuke pasi pemazana matatu emabhawa e hydraulic pressure-kana kurarama maawa gumi egasi rinovava? PaQINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Takakanda uye takagadzira pamusoro pe12,000 mavharuvhu ekumanikidza, piston pump housings, uye cobalt-alloy nozzles kubvira 2015. Takaona zviumbwa zvejecha zvichitadza kusvika 1,150°C kudurura tembiricha. Isu takarasa 47% yeAMS 5387 batch mushure mekuongororwa kwe microstructure kwakaratidza kupatsanurwa kwe interdendritic. Aya haasi emabhuku ezvinyorwa-isarudzo dzemazuva ese dzinotsanangura nheyo dzesimbi yekukanda fekitari mabasa.
Kuvimbika Kwezvinhu Hazvifungidzirwe-Kunosimbiswa
Iwe haugone kukanda zvikamu zvepamusoro-soro kubva ku "generic stainless simbi." Panzvimbo yedu yeQingdao, kupisa kwega kwega kweT800 cobalt-based alloy kunosvika kuine mishumo yakazara yebvunzo-uye isu tinoedzazve kabhoni, chromium, uye tungsten zvirimo zvisati zvanyunguduka. Sei? Nekuti kutsauka kwe0.03% mune cobalt zvemukati kunochinja solidus tembiricha ne12°C. Izvo zvinoshandura mold kutonhora mitengo. Izvo zvinokanganisa saizi yezviyo. Izvo zvinokanganisa hupenyu hwekuneta mu winch centre shaft rollers. Isu tinoshandisa OES (Optical Emission Spectrometry) pamabhawa anouya uye tinoona ASTM A957 yekudyara castings, ASTM A159 yegrey iron, uye AMS 2269 yecobalt-nickel alloys. Hapana kunze. Kwete "vimbo asi simbisa" - tinoona kutanga, tozokanda.
Kukandira Maitiro Sarudzo Inoraira Chikamu Kugona
Kukandwa kwejecha kunobata faundesheni hombe dzepombi dzinosvika 1,800 kg—asi kunoda kudzora bhinda kwakasimba kudzivirira kukanganisika kwetsinga mudzimba dzakatetepa-masirinda. Kukandira kwekudyara kunoburitsa ± 0.05 mm dimensional kudzokorora kweAMS 5387 cobalt alloy plugs-asi inoda chaiyo wax pateni yekuwedzera muripo. Isu hatisarudze imwe nzira uye kumanikidza-kukodzera zvikamu zvese. Pane kudaro, tinoronga chikamu chimwe nechimwe maererano nemitemo mitatu: reshiyo yemadziro emadziro, chinodiwa chepamusoro (Ra ≤ 1.6 µm vs. Ra ≤ 6.3 µm), uye nzira yekutakura inoshanda. Semuyenzaniso, hydraulic pressure valve body inoshandisa jecha kukanda ganda rayo rekunze-asi iyo yemukati inoyerera ndima CNC-muchina post-cast kubata GD&T kushivirira kwakasimba kupfuura ± 0.025 mm. Iyo nzira yakasanganiswa haisi sarudzo. Ndiwo maitiro aunosangana nawo ISO 8502-3 hutsanana specs * uye * ASME B16.34 kumanikidzwa ratings.
Dimensional Kugadzikana Kunotanga Mold Isati Yadururwa
Takambogamuchira dhirowa yepombi yepiston yepombi ine 12 dzakakosha bore-dzose dzakatarwa ku± 0.015 mm. Mutengi aitarisira kukanda-kusvika-kupedzisa machining. Asi kuputika kwekupisa mu ductile iron kunosiyana nechikamu chechikamu. Rusvingo rwe45-mm runodzikira 0.28% kupfuura mbabvu ye22-mm. Saka isu takavaka shrink zvibvumirano mune iyo pateni yekushandisa-kwete seyakagadziriswa offset, asi separametric curves yakasungirirwa kune yemuno yekusimbisa nguva (yakaverengerwa kuburikidza neMAGMAsoft simulation). Ipapo isu takasimbisa maitiro ekuderera nekukandwa kwechibairo bvunzo, kuyerwa paZeiss PRISMO CMM. Ipapo ndipo patakabvumidza kugadzirwa. Ichi ndicho chikonzero chekuongorora kwedu mu-process kunosanganisira 100% kurongedza kuyerwa pamatanho matatu: as-cast, mushure mekuzorora kwekushushikana, uye post-machining. Traceability haisi chirevo-inonzi laser-etched serial nhamba inobatanidza chikamu chimwe nechimwe kune yayo yakanyunguduka danda, kupisa kwekupisa curve, uye yekupedzisira CMM chirevo.
Kudzora Kwemhando Inovakwa Mune Yese Yese Yekufamba Nhanho
Mamwe mafekitori anobata QC segedhi kumagumo. Isu tinoinyudza panoitika kutadza: risiti yezvigadzirwa, kubatanidza mold, kudurura tembiricha yekutarisa, shakeout nguva, uye pre-kupisa-kuomarara kwekutarisa. Vaongorori vedu vanoshandisa inotakurika PMI pfuti kusimbisa giredhi alloy vasati vakanda-uye ultrasonic bvunzo (ASTM E114) pane yega yega-chikamu simbi inokanda pamusoro pe75 mm. Kune zvikamu zvecobalt-nickel, tinowedzera fluorescent penetrant inspection (ASTM E1417) nokuti micro-cracks inovanda mumiganhu yedendritic. Uye hongu-isu tinochengeta zvinyorwa zvese digitally kwemakore gumi nemashanu. Kwete nekuti chiyero chinodaro, asi nekuti apo European OEM yakateedzera kutadza kwemunda kune rimwe batch reAMS 5387, isu takadhonza iyo yakazara nhoroondo yekuongorora mumasekonzi makumi masere nematatu. Hapana kufungidzira. Hapana kunonoka.
The nheyo dzesimbi yekukanda fekitari budiriro inodzika kusvika kune zvitatu zvisingagone kutaurirana: chirango chesimbi, maitiro-chaiyo dimensional kufanoona, uye yekuongorora yakaomeswa yakabikwa mukufambiswa kwebasa-isina kuvharirwa pamagumo. PaQINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., izvo zvakakosha hazvisi dzidziso. Ndiwo mabudisiro atinoita mavharuvhu anomanikidza anoshanda pa450°C pasina kuvuza, dzimba dzepombi dzinochengetedza concentricity mushure memamirioni maviri ekutenderera, uye cobalt alloy nozzles inoramba kukukurwa mumapombi abrasive slurry. Sezvo kukanda-machining hybrid kuoma kunokwira-uye zviyero zvakaita seNORSOK M-650 uye API 6A inoomesa - izvo zvakakosha hazvichinje. Vanongoda kuurayiwa kwakadzama. Ndiko uko ruzivo rwunosangana neinjiniya.
