Kayayyakin Gyaran Gasa na Fure na Noma Masu Lanƙwasa da Keɓaɓɓun Gasa na Carbide don Noma Mai Yawan Aiki

Takaitaccen Bayani:

Bakin garma, wani abu mai taimako ga injunan noma, an ƙera shi ne daga ƙarfe mai ƙarfi da juriya ga lalacewa kuma ana ƙara taurinsa da ƙarfinsa ta hanyar maganin zafi. Tsarin gefensa mai kaifi yana rage juriya lokacin shiga ƙasa, yana yanke ƙasa mai tauri cikin sauƙi. Ana ƙara kauri da ƙarfafa muhimman wurare don juriya ga tasiri da juriya ga lalacewa, wanda hakan ke ƙara tsawon rayuwar aikinsa sosai. Ya dace da nau'ikan garma daban-daban da garma mai juyawa da kuma garma mai laushi, kuma sauƙin wargazawa da maye gurbinsa yana rage farashin noma da lokacin aiki.

Wannan samfurin wani muhimmin ɓangare ne na kayan aikin gona - ɓangaren garma - wanda ya dace da garma daban-daban na allon moldboard, garma mai juyawa, da garma a ƙarƙashin ƙasa. A matsayin ɓangaren da ya fara hulɗa da ƙasa kuma yana ɗaukar mafi girman gogayya da tasiri, ingancinsa kai tsaye yana ƙayyade juriyar noma, ingancin mai, da kwanciyar hankali na zurfin aiki. Wannan gefen garma yana ɗaukar tsarin haɗin gwiwa na "matrix mai ƙarfi + gradient hard alloy," yana cimma daidaito tsakanin shigar ƙasa mai kaifi, juriyar lalacewa da rage ja, da kuma taurin tasiri. Wannan yana faɗaɗa zagayen maye gurbin sosai kuma yana rage matsakaicin farashin aiki a kowace eka.

Matrix: An yi shi da ƙarfe mai ƙarfi na 30MnB ko 40Cr, wanda aka ƙera da zafi sosai, tare da yawan gaske kuma babu porosity na ciki. Bayan an ƙera shi, ana yin maganin kashewa da kuma rage zafi don samun tsarin martensitic mai zafi. Taurin tasirin matrix shine ≥50J/cm², wanda zai iya shan tasirin wucin gadi daga duwatsu da saiwoyin bishiyoyi yadda ya kamata, yana kawar da haɗarin fashewa ko karyewa.

Layi Mai Juriya Gashi: Ana amfani da walda ko rufin laser a saman gefen gona da ke fuskantar ƙasa (yankin lalacewa na gefen gaba da saman sama) don lulluɓe ƙarfe mai ƙarfi na chromium ko ƙarfe mai ƙarfi na tungsten carbide. Rufin walda zai iya kaiwa ga taurin HRC 58-62, tare da kauri na 2.5-4.0 mm, yana samar da haɗin ƙarfe da substrate kuma yana kawar da haɗarin barewa. A ƙarƙashin yanayin lalacewa mai sauri a cikin ƙasa, ƙwayoyin tauri suna samar da yanayin "ƙarancin tallafi" mai kariya, yana rage yawan lalacewa zuwa 1/3 na faranti na ƙarfe 65Mn na yau da kullun.

Tsarin Geometric: An inganta saman lanƙwasa na gefen garma bisa ga yanayin motsi mai sauƙi na dunƙulen ƙasa, yana rage kusurwar gogayya da ƙasa. Sashen gaba yana da ƙira mai kunkuntar a hankali, mai laushi, wanda ke rage matsin lamba na karya ƙasa; sassan tsakiya da na baya suna kauri a hankali don tabbatar da tauri gabaɗaya. An daidaita kusurwar shiga don nau'ikan ƙasa daban-daban (yashi, yumbu, ƙasa), tare da haɗa ingantaccen ikon shiga tare da ƙarancin juriya ga jan hankali.

Juriyar Lalacewa Mai Tsanani: Gwaje-gwajen da aka yi kan lalata tayoyin robar busasshiyar yashi a dakin gwaje-gwaje sun nuna cewa adadin lalacewar na'urar ya kai ≤0.25g/kg·m. A ƙarƙashin matsakaicin yanayin yashi, saman garma ɗaya zai iya kammala aikin eka 500-800, tare da tsawon rai sau 2.5-3 na ƙarshen garma na ƙarfe 65Mn.

Halayen Kai-tsaye: Rufewar walda mai tauri da kuma taushin substrate suna samar da lalacewa ta haɗin gwiwa - substrate ɗin yana lalacewa da sauri, yana sa barbashin carbide na siminti su ci gaba da fitowa kaɗan daga saman aiki, koyaushe suna riƙe da siffar kaifi mai kaifi kuma suna hana ƙaruwar amfani da mai saboda raguwar aiki.

Juriyar Tasiri da Tsaro: Lokacin da aka haɗu da ɓoyayyun duwatsu ko cikas masu tauri, matrix ɗin gaba ɗaya ba zai fuskanci karyewar karyewa ba, kuma nakasar gida ce kawai za ta iya faruwa; gefen filastik ya isa don guje wa tarkace da ke faɗuwa cikin filin da lalata kayan aiki na gaba.
