Kuki ubufatanye bwuruganda 17-4PH butananirwa-Nuburyo Ikipe imwe ya Qingdao ikemura buri munsi
Ba injeniyeri benshi bashakisha ibice 17-4PH bakubise urukuta rumwe: utanga isoko asezeranya imbaraga za H900 hamwe na ASTM A564 kubahiriza, hanyuma agatanga ubukana budahuye mugice kimwe - cyangwa ikibi, micro-crack nyuma yo kuvura ubushyuhe. Twabibonye mumazu ya hydraulic valve yanze guterana hagati, mumaboko ya pompe ya piston yananiwe kuri 3,200 psi, mumashini ya winch center arwanira mugihe cyo gusya bwa nyuma. Intandaro ntabwo ari ibintu bibi-ni ubushobozi butandukanye. Nukuri Uruganda 17-4PH igomba kugenzura ibyuma, gutunganya, no gutunganya ubushyuhe munsi yinzu. Ntabwo ari "ushoboye" gusa, ariko byagaragaye, birashoboka, bisubirwamo.
Igenzura rya Metallurgiki ritangira mbere yo gukora imashini
17-4PH ntabwo ari "ibyuma bidafite ingese n'umuringa." Kurwanya kwangirika kwayo hamwe na 1,100 MPa imbaraga zingana biterwa na kinetics ishaje neza: bigufi cyane, kandi imvura ntigikora; birebire cyane, kandi birababaje, bitesha agaciro ubukana. Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Buri fagitire ya 17-4PH igera hamwe na raporo yikizamini cyuzuye - yemejwe na AMS 5604 cyangwa ASTM A564 Icyiciro cya 630 - kandi ikorerwa igenzura ryinjira: igeragezwa ryumuriro, isesengura rya PMI, hamwe nubushakashatsi bwakorewe ubushyuhe mbere yuko chip ikata.
Ntabwo dushyira hanze kuvura ubushyuhe. Ikigo cyacu cyujuje ISO gikoresha itanura ryikirere hamwe na ± 2 ° C bihwanye, bigakurikirwa no kuzimya helium kugirango bikureho delta ferrite. Inzinguzingo zishaje zandikwa kuri buri kintu - ntabwo kuri buri mwanya - hamwe nigihe cyo gushushanya amakarita ya thermocouple. Igisubizo? Guhindagurika gukomeye biguma muri HRC 38-40 kumiterere ya H900, igenzurwa kumanota atatu kuri buri gice ukoresheje umunzani wa Rockwell B na C. Nta gukeka. Nta rework.
Imashini Itomoye Yubaha Ingano
17-4PH akazi-gakomera cyane. Inzira zisanzwe zitera kwambara byihuse, ibimenyetso byo kuganira, hamwe no gutembera kurwego - cyane cyane mumazu ya silinderi yoroheje cyangwa inzu yumubiri wumuvuduko mwinshi. Itsinda ryacu rya CNC rikoresha ingamba zo gusya ibiryo byinshi hamwe na PVD yashizwemo karbide yinjizwamo karbide, imihindagurikire y'ikirere igabanya ingufu za radiyo ku kigero cya 35%, hamwe na sisitemu yo gufata ibikoresho bikoreshwa kuri 12,000 rpm.
Dukora imashini zikomeye * nyuma yo gusaza - ntabwo mbere. Kubera iki? Kuberako nyuma yubushyuhe-buvura imihangayiko ihindura igice cya geometrie. Kwihanganira mm 0,015 kumiturire ya mm 200 ya diametre ntigushobora kugerwaho iyo usya mbere yubusaza hanyuma ugasaza. Ibikorwa byacu bifunga GD&T igenzura kumiterere yanyuma: kurangiza hejuru Ra ≤ 0.8 mm kuri kashe yo gufunga, kwihanganira imyanya ± 0,02 mm kumyobo yo kwishyiriraho, hamwe no kwibanda kuri 0,01 mm kubinyamakuru bya shaft - byose byapimwe kuri Zeiss CONTURA G2 CMM hamwe nubushakashatsi bwakozwe nubushyuhe.
Aho Guterana Bihura Nimbaraga-Zimbaraga Zivanze Ubuhanga
Porogaramu zigera kuri 17-4PH zisaba hafi-net-imiterere igoye bidashoboka hamwe nububiko: urufatiro rwa pompe idasanzwe, imiyoboro ikonjesha ihuriweho na valve manifolds, cyangwa ibyuma byinshi bya silinderi. Aho niho icyitegererezo cyibintu byombi gifite akamaro. Twateye 17-4PH dukoresheje gushora imari - ntabwo ari umucanga - kugirango tugere ku butumburuke buke munsi ya Ra 3.2 mm hamwe no guhagarara neza muri ± 0.3% by'ubunini bw'izina.
Ariko gutera 17-4PH bizana ibyago: kugabanya ububobere, gutandukanya ibice byimbitse, hamwe no gukuramo niba igipimo cyo gukonja gitandukanijwe na 5-10 ° C / s. Itsinda ryacu ryashinzwe rikurikirana gukomera hamwe nu mashusho yubushyuhe, rihindura igishushanyo cya gating ukoresheje imvugo ya MAGMASOFT, kandi ryemeza buri gusuka hamwe na ultrasonic test (ASTM E114) hamwe nubugenzuzi bwa macro-etch. Buri casting itwara ubushyuhe budasanzwe bujyanye na raporo y’imiti, ibiti by’umuriro, hamwe n’ibisubizo bya NDT - bikurikiranwa neza n’ibikoresho fatizo.
Kwemeza-Isi-Ntabwo ari Impapuro gusa
Kubahiriza ntacyo bivuze bidafite imiterere. Mugihe OEM yu Burayi yari ikeneye 17-4PH piston pompe ya pompe yububiko bwa pompe zo mumazi yo mumazi, bagaragaje ASTM A564, H900, hamwe no kurwanya umunyu ≥1000 kuri ASTM B117. Ariko ntibasobanuye uburyo bwo gukemura ikibazo cya mm-12 z'uburebure bwa flang-to-barrel-bizwi ko bishobora guteza ibibazo.
Twakoresheje uburyo bwo kwerekana umunaniro wa FEA, twongeramo amafuti ya radiyo yuzuye, kandi twemeza ko twongerewe ubuzima hamwe na 500.000-cycle hydraulic pulsation yipimishije kuri 4500 psi. Ibice byararenganye. Icy'ingenzi cyane, bohereje kuri gahunda - kubera ko gahunda yacu yo gutegura igenamigambi ikurikirana uburyo bwo kuvura ubushyuhe, gutunganya, no kurangiza mu buryo bubangikanye, ntabwo ari urukurikirane. Prototype yo kuyobora igihe: iminsi 18. Ubunini buringaniye (500 pcs): iminsi 32. Byose hamwe nibyangombwa bya PPAP, harimo ubushakashatsi bwa MSA na gahunda yo kugenzura.
Niba umushinga wawe utaha wa 17-4PH usaba ubunyangamugayo buringaniye mukibazo, kurwanya ruswa mubitangazamakuru bikaze, no kutihanganira na gato kubintu bitunguranye - tangirana numufatanyabikorwa ufata siyanse yivanga nkibidashoboka, ntabwo ari ubushake. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ikora nkukuri Uruganda 17-4PH: uhagaritse, uhagaritse disipuline, kandi wakozwe mubikorwa byingirakamaro. Uburyo bwabo ntabwo buhuye nibisobanuro gusa - buteganya uburyo bwo gutsindwa mbere yuko igikoresho cya mbere gikora ku cyuma.
