Iyo abajenjeri bagaragaje ibyuma bidafite ingese kumashanyarazi ya hydraulic yumuvuduko mwinshi cyangwa shitingi idashobora kwambara, ntibakunze gutura amanota asanzwe. Bakenera microstructural idahwitse, hafi-net-imiterere igoye, hamwe no guhagarara neza murwego rwo gusiganwa ku magare - ibihe aho guhimba cyangwa gukora imashini bigwa bigufi. Niyo mpamvu amakipe menshi yo gushushanya ahindukirira ifu metallurgie ibyuma bitagira umwanda-Ntabwo ari ubundi buryo bwiza, ariko nkigisubizo cyibanze kubice-byingenzi byuzuye. Kandi ikigo kimwe gihora gitanga kuri ayo masezerano ni QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD.
Ifu Metallurgie Ibyuma bitagira umuyonga: Aho Precision ihura na Metallurgical Control
Twabonye abakiriya bagaruka inshuro eshatu hamwe no gushushanya amazu ya valve imwe-yabanje gutunganyirizwa mububiko, hanyuma gushora imari, amaherezo ifu ya metallurgie (PM) ibyuma bitagira umwanda. Buri itera yakemuye ikibazo kimwe ariko itangiza ikindi: gutunganya impungenge zisigaye mugice gikikijwe; gukina byatangije porosity kumuhanda-inzira; PM yatanze ubucucike bwombi> 99.5% hamwe nuburinganire bwimbuto hejuru ya 0,05 mm yuburebure bwurukuta. Itandukaniro ntabwo ryari imikorere gusa-ryasubirwamo mubice 500-bitarinze kubisabwa.
PM ibyuma bidafite ingese ntabwo byacumuye 316L kandi byitwa ko byakozwe. Itangirana na gaze-atomize mbere-ivanze-ifu-mubisanzwe 17-4PH, 15-5PH, cyangwa ibicuruzwa bya Cr-Ni-Mo-Cu - byerekanwe kuri ± 5 µm ikwirakwizwa. Kuri QINGDAO QIANGSENYUAN, guhuzagurika ikoresha imashini ikora kabiri hamwe nogukurikirana igihe nyacyo, ntabwo tonnage ihamye. Gucumura bibaho mu itanura rya vacuum hamwe nikime cyimeza (<–40 ° C) hamwe nigipimo cya ≤5 ° C / min kugirango wirinde imvura ya chromium. Igisubizo? Ibikoresho bifite umusaruro mwinshi hejuru ya 20-30% ugereranije n’amanota ahwanye n’ibyakozwe, zeru zeru imbere zishobora kugaragazwa na test ya ultrasonic kuri 10 MHz, hamwe nubushuhe bwa Ra ≤1.6 µm nkuko byacumuye - nta gusya kwa kabiri gukenewe kubutaka budafunze.
Kuki "Uruganda" rufite akamaro kuruta "Utanga"
Abacuruzi bamwe batanga hanze. Abandi bakora imashini yanyuma. Nukuri ifu ya metallurgie uruganda rwicyuma Afite urunigi rwuzuye - kuva ifu yakira kugeza ikizamini gikora - kandi QINGDAO QIANGSENYUAN arabikora neza. Ikigo cyabo cya Qingdao gihuza imirongo ya PM 900 yemejwe na PM hamwe na selile 5-axis ya CNC, amashyiga yo kuvura ubushyuhe yahinduwe kuri AMS 2750E, hamwe na laboratoire ya metero ya CMM ikoresha sisitemu ya Zeiss CONTURA G2.
Uku kugenzura guhagaritse gukuraho ingingo ebyiri zisanzwe zananiranye: Icya mbere, ibintu bifatika. Buri cyiciro gitwara MTRs yuzuye - ntabwo ari amakuru yuzuye gusa, ahubwo ni ibisigisigi bya ogisijeni / azote, raporo zisesengura, hamwe nibiti byangiza ikirere. Icya kabiri, ubudahemuka bwa geometrike. Mugihe umukiriya yasabye icyuma cya pisitori ya pisitori ifite ibyambu 8 bikonjesha bya radiyo, kwihanganira mm 0,01 mm, hamwe nubutaka bukomeye bwo gufunga, itsinda ryateje imbere icyatsi kibisi cya geometrie, ikarita y’indishyi zagabanijwe, hamwe n’ikosorwa ry’ubushyuhe nyuma yo gukosorwa - byose mbere yo gukata ibikoresho.
Porogaramu nyayo, ntabwo ari Cataloge gusa
Reba hejuru yamakuru. Mubikorwa byukuri, PM yabo ibice bitagira umwanda bikemura ibibazo byumurima:
- Amavuta na gaze kumanuka.
- Ubwubatsi bwimodoka winch center shafts: Ibice bya T800 bishingiye kuri PM bikora 3 × birebire kuruta ibihimbano bihwanye nu munyu-spray byihuta byo kugerageza, bitewe no gukwirakwiza karbide imwe ikuraho inzira zo kwambara.
- Imashini yihuta cyane: Net-shusho yacumuye amazu 17-4PH igabanya igihe cyo guterana ku kigero cya 65% ugereranije nibice byinshi byashushanyije, nta gasketi yamenetse kuri 450 itandukanye.
Ibi ntabwo aribyiza byo kwigisha. Nibisubizo byagenzuwe binyuze mubigenzuzi byabakiriya-ntibigana laboratoire yonyine.
Ibyo Abashakashatsi bakeneye kumenya mbere yo kwerekana
Ibintu bitatu bifatika byerekana PM igenda neza:
- Igishushanyo cyo gucumura mbere: Gucengera kurenze 3 × uburebure bwurukuta bisaba gukora kabiri. Radiyo ntarengwa ni mm 0.2 - ntabwo 0,05 mm nka EDM. Turagira inama yo gusuzuma hakiri kare GD&T dukoresheje serivise yubuntu yubuntu.
- Ingano yubukungu ihinduka kuri 250: Munsi yibyo, gukoresha amortisation bituma PM ihenze kuruta CNC. Hejuru yacyo, igiciro cyubutaka cyagabanutseho 18-22% kubera 70% imyanda mibi mike hamwe na 40% mugihe gito cyo kuyobora.
- Kurangiza isura ntabwo ari ubushake-birakora. Nta na kimwe kidasanzwe.
Ntibasunika PM aho itari - nkibice binini byubatswe cyangwa amazu yumuvuduko muke. Intego zabo ziguma zifunganye: ibice-byerekana neza aho ubucucike, kurwanya ruswa, hamwe no guhagarara neza.
Kureba imbere: Kuva ku ruganda kugera kuri Fondasiyo-Imashini ya Hybrid
Imipaka ikurikira ntabwo ari nziza gusa PM idafite - ni inganda zivanze. QINGDAO QIANGSENYUAN ubu yujuje ibyangombwa byuzuzanya: gucumura umubiri hafi ya net valve, hanyuma ugakora laser yometse kuri Stellite 6 hejuru yikimenyetso, hanyuma igakurikirwa no kurangiza muburyo bumwe bwa CNC. Ibi bivanaho ubushuhe budahuye hagati yifatizo nibikoresho byuzuye - impamvu izwi yo gutera imburagihe mugihe gikoreshwa cyane.
Kuri ba injeniyeri basuzuma abaguzi, baza ibibazo bitatu: Bashobora kukwereka ibiti byangiza ikirere kurutonde rwawe rwa nyuma? Bakora murwego rwo kugenzura ubucucike - ntabwo ari igice cyanyuma cyo kugenzura? Kandi bazafatanya guteza imbere GD&T stack-up mbere yo gukanda gutangira? Niba igisubizo ari yego kuri bose uko ari batatu, urimo ukorana na ifu ya metallurgie uruganda rwicyuma—Ntabwo ari undi mucuruzi. Itandukaniro risobanura kwizerwa mugihe imikorere idashobora guhungabana.
