Apo mainjiniya anotsanangura machined iron casting kune mavharuvhu e hydraulic, pombi dzimba, kana mawinch shafts, havasi kungoraira chikamu-vari kuzvipira kudzikama pasi pe350-bar pressure, microstructural kuperera mushure mekupisa bhasikoro, uye kupera kwepamusoro kunoramba kusakara muhova dzemafuta dzakaremerwa nejecha. Takaona mapurojekiti akawandisa achimira apo vatengesi vanobata iron cast sechinhu chekutengesa- vobva vasiya machining kuchitoro chechitatu chine dudziro isingaenderane neGD&T, marekodhi ekurapa kupisa kusingaenderane, kana kusateedzerwa kweASTM A48 Kirasi 350 mabhechi.
Nei Kukandwa Kwesimbi Kuchikundikana-Uye Zvinonyatso shanda
Kukanda simbi chete hakuvimbisi kushanda. Gray iron's graphite flakes inopa kunyorova asi inoderedza kusimba kwesimba; ductile iron's spheroidal graphite inovandudza kuoma asi inoda chaiyo nodularization control panguva yekudira. Wedzera CNC machining-uye iwe unounza mitsva yekutadza mavheji: yakasara yekushushikana kukanganiswa kubva mukutonhodza kusina kuenzana, chatter mamaki pane dzakatetepa-yakavharidzirwa cylinder bores, kana kuomarara kwemagetsi izvo zvinokonzeresa kupfekedzwa kwechishandiso nguva isati yakwana panguva yekupedzisira.
Isu takambogadzirisa zvakare batch yepiston pombi silinda dzimba nekuti iyo yekutanga yakashandisa yakadzoreredzwa zvimedu pasina spectral verification. Yakazokonzeresa kusiana kwesilicon kwakachinja kuomarara kubva pa220–240 HB kuenda pa265 HB munzvimbo dzenzvimbo-zvakakwana kutsausa 0.012 mm panguva yekufinha. Ndosaka tichiyedza kunyungudika kwese neOES ongororo * isati yadururwa-uye kuona kuomarara kwemashure-kukandwa munzvimbo nhatu pakukanda, kwete imwe chete.
Kubudirira kwepasirese chaiko kunotsamira pakubatanidza kwakatwasuka. Foundry, chitoro chemuchina, uye metrology inofanirwa kugovera imwe yenhoroondo yekupisa, chirongwa chimwe cheCMM, chitupa chimwe chete. Hapana handoffs. Hapana fungidziro nezve "yakajairwa" machining mvumo. Kana mutengi achititumira AMS 5387 cobalt alloy plug yekudhirowa ne ± 0.005 mm chinzvimbo chekushivirira pamaburi matanhatu edowel, tinopindura mukati meawa 48-kwete nekotesheni, asi nemushumo wekugadzira unoratidza uko EDM drilling inorova twist drilling, uko kushushikana-kubvisa kusati kwaitwa roughity, kunodzivirira kutenderera kwe CONT uye kunodzivirira kutenderera kwatinoita. G2 ine mhepo inopinza mhepo.
Zvina Zvisingataurwi zveMission-Critical Iron Castings
- Material traceability kusvika kunhamba yekupisa-kwete zvigayo chete, asi yakazara OES mishumo, tensile bvunzo mabara akachengetwa pamujenya, uye microstructure mapikicha akasimbiswa neASTM E112
- Machining mushure mekunetseka kwekunetseka-tinobata ma castings pa 550 ° C kwemaawa mana, tozotonhorera pa ≤30 ° C / awa isati yatanga kubviswa kwesimbi.
- GD&T-yekutanga kuronga kuronga-CMM maitiro akavakirwa kubva mutengi kudhirowa, kwete generic matemplate; datum maficha akaferefetwa kutanga, anoshanda ekupedzisira
- Surface kutendeseka kusimbiswa-kwete chete Ra kukosha, asi chena-layer kuonekwa kuburikidza neSEM/EDS yekuisa chisimbiso zviso zvakafumurwa kuH2S sevhisi.
Iko Vatengesi veShambadziro Vanowira Pfupi (Uye Maitirwo eKuzviona)
Vamwe vatengesi vanoshambadzira "chaiyo machined iron casting" asi outsource casting kune yakaderera-mutengo foundries isina ISO 9001: 2015 Clause 8.5.2 inodzora kune isingaenderane chigadzirwa. Vamwe vanoshandisa generic CNC zvirongwa zvinotora yunifomu yemvumo yemasheya- vachiregeredza kuti kukanda kwejecha kunokanganisa sei kukora kwemadziro mune yakaoma geometries senge engineering mota winch centre shaft rollers.
Takabata gaka iri panguva yekuongorora nguva pfupi yadarika: mumwe mukwikwidzi akataura muviri wevharuvhu ine 12-mm mashoma emadziro ukobvu-asi yavo yekukanda dhizaini yaingoratidza 8-mm yezita mvumo. Mukuita, 30% yezvikamu zvaida weld kuvaka-up machining asati atanga. Icho hachisi chokwadi. Ndiko kufungidzira kwakavharwa sekugona.
Bvunza mutengesi wako iyi mibvunzo usati waburitsa maPO:
- Unogona kundiratidza here matatu ekupedzisira anonyungudusa matanda eASTM A ductile iron?
- Ndeipi kutsauka kwako kukuru kunobvumidzwa pakati pe-se-cast uye yekupedzisira-muchina uremu hwe42-kg pombi hwaro?
- Ko yako CMM mishumo inosanganisira yekupisa yekudonha muripo data yakadhindwa panguva ye8-awa yekuongorora hwindo?
Kuvaka Kuvimbika—Kwete Zvikamu Zvimwechete
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. delivers machined iron casting mhinduro apo kuvimbika kusingagone kutaurirana-kwete nekuti tinozvitaura, asi nekuti maitiro edu anosiya humbowo. Yese yekumanikidza vharafu inotakura ine QR-coded label inobatanidza kune yayo yakazara yekuongorora dossier: mbishi zvinhu certs, kupisa kupisa machati, CMM point makore, uye roughness mepu. Vatengi muNorth America neEurope vanoshandisa iwo mafaera eASME Chikamu VIII Chikamu UG-120 kutevedzera maodhita. Maodzanyemba ekumabvazuva kweAsia OEMs anoataura panguva yeAPQP Stage 3 ongororo.
Isu hatidzingire volume. Isu tinotarisisa pane zvikamu izvo kutadza kunoreva kuderera, njodzi yekuchengetedza, kana chirango chekutonga-seT800 cobalt-based nozzles inobata 450 ° C yakanyungudutswa munyu mumiviri yezuva. Ikoko, 0.02-mm bore taper haisi "kutsauka kudiki." Iko kusaenzana kwekuyerera kunowedzera kukukurwa ne300%.
Ramangwana ndere hybrid maitiro: investment-cast near-net shapes ine CNC-machined sealing land, sand-cast housings ine integrated coolant channels inopedzwa nehigh-speed milling. Isu tiri kuwedzera R&D yedu pane inodzorwa-kutonhora kukanda mold uye kugadzira mukati-maitiro vibration yekutarisa yechokwadi-nguva yekuona chatter panguva yakadzika-gomba kufinha kwecylinder block.
Kana yako inotevera purojekiti inoda machined iron casting iyo inobata chokwadi pa 300 ° C, inopona 10⁶ kutenderera, uye inosvika ne zero dimensional zvinoshamisa-kutanga nekutsvaga kwezvinhu, kwete mutengo pa kilogram.
