Spring harbi ayukan iska mai ƙarfi tsari
Shot ayukan iska mai ƙarfi ƙarfi (wanda kuma aka sani da harbi peening ƙarfafa) na spring harbi ayukan iska mai ƙarfi ƙarfafa inji shi ne wani key surface jiyya tsari, da nufin inganta gajiyar rayuwa da danniya lalata juriya na marẽmari. Ba a samun tasirinsa ta hanyar "ji", amma ana sarrafa shi kuma an tabbatar da shi ta hanyar jerin ma'anoni masu tsauri da ƙididdigewa.
Za a iya rarraba ainihin ma'auni na ƙarfafa fashewar harbe-harbe na bazara zuwa manyan sassa uku: alamun sarrafa tsari, alamun tabbatar da sakamako da alamun garantin aiki.
I. Ma'anonin Sarrafa Tsari na Na'urar Ƙarfafa Fashewa (Tabbatar Madaidaicin Ma'auni)
Dole ne a sa ido da yin rikodin waɗannan alamomin a ainihin lokacin yayin aikin fashewar harbi.
Ƙarfin fashewar harbi (ƙarfin Almen)
Ma'anar: Wannan shine mafi mahimmancin ma'aunin sarrafa tsari. Auna ta amfani da daidaitattun gudan gwajin Almen (yawanci rubuta A ko Nau'in N). Gyara yanki na gwaji a wuri ɗaya da bazara. Bayan samun fashewar fashewar harbi, yanki na gwajin zai iya zuwa wurin da ake harbawa. Auna tsayin baka tare da ma'aunin tsayin baka.
Ƙimar tsayin baka lokacin da aka kai madaidaicin madaidaicin (watau lokacin da lokacin fashewar harbi ya ninka sau biyu, haɓaka tsayin baka bai wuce 10%) shine ƙarfin fashewar harbin ba. Naúrar: Millimeta (mm) ko inch (inch), misali 0.35mmA.
Ma'ana: Ƙarfi mara ƙarfi, ƙarancin ƙarfin ƙarfafawa; Ƙarfin da ya wuce kima na iya lalata ƙasa ko haifar da canje-canjen girma.
Yawan ɗaukar hoto
Ma'anar: Adadin yanki na raƙuman ruwa bayan ƙarfafawa zuwa jimlar yanki{0}% ɗaukar hoto yana nufin cewa saman yana rufe gaba ɗaya kuma a ko'ina da ramuka.
Nuni: Ƙarfafa lokacin bazara yawanci yana buƙatar ƙimar ɗaukar hoto sama da ko daidai da 200% (watau, sau biyu lokacin da ake buƙata don cimma ɗaukar hoto 100%). Wannan shi ne don tabbatar da cewa dukkanin wurare, musamman ma ƙananan ƙananan ƙananan ƙwayoyin cuta, suna da cikakkiyar magani.
Hanyar dubawa: Kwatanta tare da daidaitaccen bakan a ƙarƙashin na'urar hangen nesa, ko amfani da software na nazarin hoto na ƙwararru.
Kayan abu, girman da siffar projectile
Material: Yawanci ana amfani da su ana jefa harbin karfe, harbin bakin karfe da harbin yumbu. Ya dogara da kayan bazara (misali, ƙwallan yumbu ana amfani da su akai-akai don manyan maɓuɓɓugan ruwa na matsananciyar damuwa).
Girma: Dole ne a sarrafa shi sosai. Misali, Φ0.3mm, Φ0.5mm, da dai sauransu. Ƙananan ƙananan pellets na iya samar da mafi ƙanƙanta amma matsananciyar damuwa, yana sa su dace da filaye masu kyau. Manya-manyan pellet - na iya haifar da matsi mai zurfi.
Siffa: Ana buƙatar ya zama mai siffar zobe, ba tare da kaifi ko sasanninta ba, kuma ba tare da lalacewa ba. Karyewar tsintsiya madaurinki ɗaya na iya tashe saman bazara kuma dole ne a cire su ta hanyar tsarin rarrabuwa.
Lokacin fashewar harbi
Lokacin aiki da ake buƙata ƙarƙashin ƙayyadaddun ƙarfi da buƙatun ɗaukar hoto. Yana buƙatar ƙayyade ta hanyar gwaje-gwajen tsari.
Ii. Alamun Tabbatar da Sakamakon Ƙarfafa Injin Ƙarfafa Ƙarfafa Ƙarfafawar Na'ura (Ma'auni Kai tsaye na Ƙarfafa Tasiri)
Ana buƙatar auna waɗannan alamomi akan maɓuɓɓugan ruwa masu ƙarfi ko samfuran wakilci.
Surface matsa lamba danniya da danniya Layer zurfin
Ma'anar: Girman ragowar damuwa na matsawa da aka gabatar ta hanyar fashewar fashewa a saman kayan da rarraba ta tare da zurfin jagora.
Hanyoyin aunawa: X{0} ray diffraction (XRD), hanyar hakowa, da sauransu. Wannan ita ce mafi kai tsaye da hanyar tabbatar da kimiyya.
Nuni
Matsakaicin ƙimar danniya mai matsawa: Yakan kai ga kololuwar sa a wani wuri a ƙarƙashin ƙasa (kamar -800 MPa zuwa -1200 MPa).
Compressive stress layer depth: The depth at which the residual compressive stress decays to zero. For high-performance springs, it is required to have a sufficiently deep effective stress layer (for example, >0.1mm).
Ƙunƙarar saman
Ma'anar: Harbin fashewa yana ɗan canza yanayin halittar jiki.
Nuni: ƙimar Ra (Ma'anar Ma'anar Lantarki na Kwanewa). Ƙimar Ra za ta ƙaru bayan harbe-harbe, amma dole ne a sarrafa ta a cikin kewayon da aka yarda (misali, Ra Kasa da ko daidai da 3.2 μm). Ƙunƙarar ƙanƙara mai yawa zai iya zama sabon tushen gajiya kuma ya hana tasirin ƙarfafawa.
Mutuncin saman
Ma'anar: Dubawa na gani ko gani don tabbatar da cewa saman ba shi da 'yanci daga fashewar harbin da ya wuce kima (wanda ke haifar da "bawon lemu" ko ƙananan kararraki), haɗaɗɗen harbe-harbe, da wuraren lalata da sabon ƙarfe ya haifar.
Iii. Alamun Tabbacin Aiki na Na'urar Ƙarfafa Fashewa (Tabbatar Ƙarfafa Tasirin Ƙarshe)
Wannan shine tabbataccen ƙarshe na aikin ƙarfafa fashewar harbi.
Yawan inganta rayuwa ga gajiya
Ma'anar: Ana ƙididdige shi ta hanyar kwatanta sakamakon gwajin gajiya na maɓuɓɓugan ruwa kafin da bayan ƙarfafawa a kan benci.
Nunawa: Gabaɗaya, ana buƙatar rayuwar gajiya (yawan zagayowar zuwa karaya) sau da yawa ko ma tsari na girma ko fiye. Misali, tsawon rayuwar bazara ba tare da fashewar harbe-harbe ba shine sau 500,000, kuma ana buƙatar isa fiye da sau miliyan 2 bayan fashewar harbi. Wannan shine ainihin ma'aunin aikin da masu amfani suka fi kulawa dashi.
Juriya na shakatawa / iya tsayayya da shakatawa na danniya
Ma'anar: Ƙarfin maɓuɓɓugar ruwa don kiyaye ƙarfin sa na roba ƙarƙashin dogon lokacin lodawa. Harba fashewa na iya inganta wannan aikin sosai.
Hanyar gwaji: Tsaya na wani ɗan lokaci ƙarƙashin ƙayyadadden zafin jiki da kaya, kuma auna adadin asarar kaya (ko tsayi). Adadin asarar bayan fashewar fashewar ya kamata ya zama ƙasa da na sassan da ba a harbe ba.
A taƙaice, ƙarfafa harbin lokacin bazara ba kawai tsari ne mai sauƙi na "buga" ba, amma tsarin injiniya na zamani wanda ya ƙunshi madaidaicin sarrafa siga, tabbatar da auna kimiyya da gwajin gajiya na ƙarshe. Wurare marasa ƙwararru ko daidaikun mutane da ke ƙoƙarin harbe-harbe a kan silinda gas.
