Karya al'adu don cimma abin mamaki: Fasahar rufe laser tana ƙirƙirar "sulke mai ƙarfi" don pistons

A cikin zuciyar masana'antar zamani - tsarin hydraulic da ruwa - mai famfo, a matsayin babban abin motsi, wanda halayen samansa ke tantance aminci, inganci, da tsawon rayuwar sabis na tsarin gaba ɗaya. Na dogon lokaci, lalacewa, tsatsa, da gajiya sun kasance ƙalubalen da ke tattare da masu fiɗa na gargajiya ke fuskanta. A yau, muna so mu gabatar muku da wata fasaha mai juyi ta ƙarfafa saman: rufin laser. Tare da manyan fa'idodinta na "daidaitaccen matakin micrometer" da "haɗin ƙarfe," wannan fasaha tana buɗe sabon babi a cikin inganta aikin fiɗa.

I. Kalubalen Gargajiya: Kurakuran da ke tattare da Juriyar Yaduwa a Fannin Famfo

Ana yin amfani da bututun mai maimaita motsi a cikin yanayi mai ƙarfi da sauri, da kuma cikin hanyoyin sadarwa masu rikitarwa, wanda ke haifar da ci gaba da fuskantar gogayya da tasiri mai tsanani. Ko da lokacin da aka ƙera shi da ƙarfe mai inganci, hanyoyin magance zafi na gargajiya ko dabarun rufewa da chrome mai tauri har yanzu suna da iyaka mai yawa.

Rufin yana da siriri kaɗan (yawanci

Rufin da kayan tushe suna da alaƙa ne kawai da injina, wanda hakan ke sa ɓarna ta fi faruwa.

Tsarin shafa chrome yana fuskantar ƙalubale masu tsanani na kare muhalli.

Kudin maye gurbin bututun gaba ɗaya yana da matuƙar tsada, kuma lokacin dakatarwar da aka samu yana haifar da asara mai yawa.

Waɗannan ƙuntatawa sun zama manyan matsaloli waɗanda ke takaita aikin famfunan plunger na dogon lokaci da inganci.

II. Juyin Juya Halin Fasaha: Menene rufin laser?

Rufin Laser, wanda aka fi sani da "ƙarfe mai jagora," wata fasaha ce ta injiniyan saman da ke amfani da hasken laser mai ƙarfi don narke kayan ƙarfe masu aiki da ƙarfi nan take tare da saman kayan tushe, wanda ke ba da damar ƙarfafawa cikin sauri da kuma samar da wani Layer mai kauri, mara ramuka, mara fashewa.

Wannan tsari yayi kama da "walda mai sassaka mai sauƙi": A ƙarƙashin jagorancin tsarin CNC mai daidaito, hasken laser yana tafiya daidai tare da hanyar da aka riga aka tsara, "haɗawa da yin ado" nanoscale tungsten carbide, foda mai tushen cobalt, ko nickel akan takamaiman wurare na saman plunger. Ana iya daidaita kauri na Layer ɗin rufewa cikin sassauci tsakanin kewayon 0.2 zuwa 3.0 mm, wanda ke ba da damar daidaita aiki daidai - duk inda ake buƙatar ƙarfafawa, ana amfani da ƙarfafawa daidai.

III. Me yasa rufin laser shine "zaɓi mafi kyau" don ƙarfafa bututun ruwa?

Taurin ya ƙaru sosai, kuma juriyar sawa ma ta ninka sau biyu.
Taurin layin rufe laser zai iya kaiwa HRC 60–70 (kimanin HV 700–1000), wanda ya ninka na ƙarfe mai inganci sau 1.5–2 da kuma na yadudduka masu rufi na chromium na gargajiya sau 2–3. A cikin gwaje-gwaje a ƙarƙashin yanayi mai tsauri, kamar waɗanda aka fuskanta a cikin tallafin hydraulic na kwal da famfunan haƙo mai, matsakaicin tsawon rayuwar pistons yana ƙaruwa da kashi 300%–500%.

Haɗin ƙarfe yana da ƙarfi sosai, yana tabbatar da cewa an hana barewa gaba ɗaya.
A yanayin zafi mai yawa, layin rufin da kayan tushe suna haɗuwa da juna, suna samar da yankin canji na ƙarfe mai kauri kusan 50-100 μm. Ƙarfin haɗin da aka samu ta wannan hanyar zai iya wuce kashi 80% na ƙarfin kayan tushe, ta haka ne za a magance matsalar zubar da shafi.

Daidaitaccen gyare-gyare da ƙoƙarin gyara yana ba da damar sake yin gyare-gyaren fasaha.

Ƙarfafawa ta gida: Ana amfani da ƙarfafawa ne kawai ga muhimman wurare kamar su maƙallan rufewa da sassan da ke ɗauke da matsin lamba, don haka yana rage farashi.

Tsarin Gradient: Yana cimma ingantaccen tsarin aiki wanda ke ci gaba daga kayan tushe zuwa saman, yana nuna yadudduka na tauri, tauri, da juriya ga lalacewa.

Sake Amfani da Sassan da aka Yi Amfani da su: Ana gyara hannayen riga da aka yi amfani da su ta hanyar rufe su, gyara girmansu na asali da kuma inganta aikinsu. Kudin wannan tsari shine kashi 30% zuwa 40% kawai na kudin siyan sabbin sassa.

Tsarin kera kore: zuwa ga ci gaba mai ɗorewa
Duk tsarin ba shi da gurɓataccen ƙarfe mai nauyi da kuma fitar da ruwan shara, kuma yawan amfani da kayan ya wuce kashi 95%. Wannan fasaha ce ta sake kera kayayyaki wadda ta ƙunshi manufar kera kayan kore.

IV. Maganin Tsarin: Canza fa'idodin fasaha zuwa ƙimar abokin ciniki

A Green Laser Tech, ba wai kawai muna samar da kayan aiki na zamani ba, har ma muna ƙoƙarin samar wa abokan ciniki cikakkun mafita don ƙarfafa saman pistons.

Tsarin gyaran da aka tsara kafin a yi amfani da shi: Wannan tsarin yana amfani da haɗin ƙananan yashi da kuma tsaftace laser don tabbatar da cewa saman substrate ɗin yana da tsabta sosai, don haka yana shimfida harsashin rufin da aka yi da inganci.

Kayan aikin injin rufewa mai wayo da yawa: An tsara shi musamman don abubuwan juyawa kamar pistons, yana da tsarin ciyar da foda mai daidaitawa da tsarin auna zafin jiki na ainihin lokaci, wanda ke ba da damar rufe saman hadaddun abubuwa iri ɗaya.

Bayanan kayan suna ba da tallafi ta hanyar samar da dabarun kayan aiki sama da 30, waɗanda aka rarraba zuwa manyan rukuni 8, don dacewa da yanayi daban-daban na aiki kamar niƙa danshi, niƙa busasshiyar hanya, da lalacewar tsatsa.

Tsarin Ƙwararrun Tsarin Aiki: Ya haɗa da ɗaruruwan fakitin tsari da aka riga aka tsara don rufin bututu, wanda ya ƙunshi cikakken kewayon samfura - daga ainihin ƙwanƙolin bawul mai diamita na 20 mm zuwa manyan bututun silinda na hydraulic mai diamita na 500 mm.

Cikakken tsarin kula da ingancin aiki rufe-map: Ta hanyar haɗa tsarin sa ido kan layi da tsarin gwaji na offline, ana tabbatar da cewa karkacewar taurin samfurin ya kai ≤3%, karkacewar kauri ya kai ≤5%, kuma kauri a saman Ra ya kai ≤0.8μm.

V. Nazarin Shari'a Mai Muhimmanci: Yadda Lambobi Ke Nuna Ikon Canji

Aikin gyaran ma'adinan kwal na hydraulic

Ga wani babban rukunin injinan kwal na cikin gida, an gyara pistons na ginshiƙai na φ360mm. Kudin rufe kowanne sashi ya kai kimanin yuan 12,000. Sakamakon haka, an tsawaita tsawon rayuwar waɗannan sassan daga watanni 8 zuwa sama da shekaru 3, wanda hakan ya ba wa abokin ciniki damar adana sama da yuan miliyan 4 a cikin kuɗin maye gurbinsu a kan lokaci.
