Kawirikawiri, bawuti mutu aumbike ozizira mutu processing pulasitiki, poyerekeza ndi kudula processing, zitsulo CHIKWANGWANI (zitsulo waya) pamodzi mawonekedwe a mankhwala ndi mosalekeza, popanda kudula pakati, amene bwino mphamvu ya mankhwala, makamaka Kupanga mutu wozizira kumaphatikizapo kudula ndi kupanga, kudina kamodzi, kuwirikiza kawiri - dinani mutu wozizira ndi mitu yambiri - malo ozizira okha. .Simplex pang'ono kapena Mipikisano siteshoni zodziwikiratu ozizira mutu makina ntchito processing makhalidwe akusoweka choyambirira amapangidwa ndi zinthu kukula 5 mpaka 6 mita bar yaitali kapena kulemera ndi 1900-2000 makilogalamu kukula kwa waya ndodo zitsulo waya, processing. luso ndi makhalidwe ozizira mutu kupanga si odulidwa pepala akusowekapo pasadakhale, koma AMAGWIRITSA NTCHITO zodziwikiratu ozizira mutu makina lokha ndi bala ndi waya ndodo zitsulo waya odulidwa ndi kukhumudwitsa akusowekapo (ngati n'koyenera) .Pamaso pa extrusion patsekeke, ndi akusowekapo ayenera kupangidwanso. Chopandacho chingapezeke popanga shaping. Chopandacho sichifuna kupangidwa chisanayambe kukhumudwitsa, kuchepetsa m'mimba mwake ndi kukanikiza. Chopandacho chikadulidwa, chimatumizidwa ku malo okhumudwitsa ogwirira ntchito. kupanga mphamvu ya siteshoni yotsatira ndi 15-17%, ndikuwonjezera moyo wa nkhungu.Kulondola komwe kumapezeka ndi kupanga mutu wozizira kumakhudzananso ndi kusankha njira yopangira ndi njira yogwiritsidwa ntchito.Kuonjezera apo, zimadaliranso Makhalidwe a zida zomwe zimagwiritsidwa ntchito, mawonekedwe a ndondomeko ndi chikhalidwe chawo, kulondola kwa chida, moyo ndi digiri ya kuvala. Pakuti chitsulo chachitsulo chosungunuka chomwe chimagwiritsidwa ntchito pozizira mutu ndi extrusion, kuuma kwapamwamba kwa alloy alloy kufa sikuyenera kukhala Ra = 0.2um, pamene ntchito pamwamba roughness wa imfa zimenezi kufika Ra = 0.025-0.050um, ali ndi moyo pazipita.
Ulusi wa bawuti nthawi zambiri umakonzedwa ndi kuzizira, kotero kuti wononga yopanda kanthu mkati mwa m'mimba mwake imakulungidwa kudzera mu mbale ya ulusi (kufa), ndipo ulusiwo umapangidwa ndi kukakamiza kwa mbale ya ulusi (kufa). Imagwiritsidwa ntchito kwambiri chifukwa ulusi wa pulasitiki wa ulusi wa screw sunadulidwe, mphamvu imachulukitsidwa, kulondola ndipamwamba ndipo khalidwe ndilofanana. chifukwa zimachepa ndi kulondola kwa ulusi, kaya zokutira zakuthupi ndi zinthu zina.Kugudubuza (kugudubuza) kukanikiza ulusi ndi njira yopangira mano a ulusi ndi mapulasitiki apulasitiki. Kugubuduza waya mbale) kufa, mbali imodzi kuti extrude cylindrical chipolopolo, mbali ina kupanga kasinthasintha chipolopolo, yomaliza kugubuduza kufa pa mawonekedwe conical anasamutsidwa kwa chipolopolo, kuti ulusi forming.Rolling (kupaka) kuthamanga ulusi processing mfundo wamba. kuti chiwerengero cha kugubuduza chisinthiko si kwambiri, ngati kwambiri, dzuwa ndi otsika, pamwamba pa ulusi mano mosavuta kubala kulekana kapena osokonezeka buckle chodabwitsa. M'malo mwake, ngati chiwerengero cha zipolowe ndi chochepa kwambiri, ulusi m'mimba mwake ndi kosavuta kutaya bwalo, kugubuduza kuthamanga kwachilendo kuchulukitsidwa koyambirira, kumabweretsa kufupikitsa moyo wakufa. Zowonongeka zodziwika bwino za ulusi wopindika: ming'alu ya pamwamba kapena zokanda pa ulusi; Zomangamanga zomangira; ulusi wachoka mozungulira. zolakwika zimachitika mu Ziwerengero zazikulu, zidzapezeka mu gawo lokonzekera.Ngati chiwerengero chochepa cha zolakwikazi chikuchitika, ndondomeko yopangira sidzazindikira zolakwika izi zidzayenda kwa wogwiritsa ntchito, zomwe zimayambitsa mavuto.Chifukwa chake, nkhani zazikuluzikulu zowonongeka ziyenera zifotokozedwe mwachidule kuwongolera zinthu zofunika izi popanga.
Zomangira zamphamvu kwambiri ziyenera kutenthedwa ndikutenthedwa molingana ndi zofunikira zaukadaulo.Cholinga cha chithandizo cha kutentha ndi kutenthetsa ndikuwongolera mawonekedwe athunthu a zomangira kuti akwaniritse mtengo wake wamphamvu komanso kupindika kwamphamvu. khalidwe lamkati la zomangira zamphamvu kwambiri, makamaka khalidwe lake lamkati. Choncho, kuti apange zomangira zamphamvu kwambiri, m'pofunika kukhala ndi zipangizo zamakono zothandizira kutentha kwapamwamba. wononga ulusi, zipangizo kutentha kutentha chofunika kukhala lalikulu mphamvu kupanga, digiri mkulu wa zochita zokha ndi khalidwe labwino la kutentha treatment.Since 1990s, mosalekeza kutentha mankhwala kupanga mzere ndi mlengalenga zoteteza wakhala pa udindo waukulu. The mantha-pansi mtundu ndi ukonde lamba ng'anjo makamaka oyenera kutentha mankhwala ndi tempering ang'onoang'ono ndi sing'anga-kakulidwe fasteners.Tempering mzere pambali pa ng'anjo losindikizidwa ntchito ndi zabwino, komanso ali patsogolo mlengalenga, kutentha, ndi magawo ndondomeko ya Kuwongolera pakompyuta, kulephera kwa zida ndi ntchito zowonetsera. Zomangira zolimba kwambiri zimayendetsedwa zokha kuchokera ku kudyetsa - kuyeretsa - kutenthetsa - kuzimitsa - kuyeretsa - kutenthetsa - kuyika utoto pa intaneti, kuwonetsetsa bwino kutentha kwamankhwala. The decarburization of screw thread zidzachititsa kuti chomangira chiyende choyamba pamene chikulephera kukwaniritsa kukana kwa zofunikira zamakina, zomwe zidzapangitsa kuti screw fastener kutaya mphamvu ndikufupikitsa moyo wautumiki. yaiwisi decarbonization wosanjikiza deepened.Panthawi yozimitsa ndi kutentha kutentha mankhwala, ena oxidizing mpweya nthawi zambiri amabweretsedwa kuchokera kunja ng'anjo.The dzimbiri la bar zitsulo waya kapena zotsalira pa waya waya pambuyo ozizira kujambula adzakhala kuwola pambuyo Kutentha mu ng'anjo. , kupanga ena oxidizing gas.Steel waya pamwamba dzimbiri, mwachitsanzo, amapangidwa ndi chitsulo carbonate ndi hydroxide, pambuyo kutentha adzasweka mu CO ₂ ndi H ₂ O, motero kukulitsa decarburization.Zotsatira zikusonyeza kuti decarburization digiri. wa sing'anga mpweya aloyi zitsulo ndi zoopsa kwambiri kuposa mpweya zitsulo, ndipo yachangu decarburization kutentha ndi pakati pa 700 ndi 800 digiri Celsius. Chifukwa chomangira pamwamba pa waya zitsulo kuwola ndi kuphatikiza kukhala mpweya woipa ndi madzi pa liwiro kusala pansi zina. zinthu, ngati mosalekeza mauna lamba ng'anjo kulamulira gasi si koyenera, adzachititsanso wononga wononga decarbonization cholakwika.Pamene mkulu-mphamvu bawuti ndi ozizira mutu, zopangira ndi annealed decarburizing wosanjikiza osati akadalipo, koma extruded kwa pamwamba pa ulusi, zomwe zimabweretsa kuchepa kwa makina (makamaka mphamvu ndi kukana kwa abrasion) pamwamba pa zomangira zomwe zimafunika kuumitsa. kuzimitsa kungabweretse padziko cracks.Chotero, kuteteza ulusi pamwamba pa decarburization mu kutentha quenching, komanso zipangizo wakhala amtengo TACHIMATA mpweya decarburization wa fasteners, kutembenukira mwayi mauna lamba ng'anjo zoteteza chikhalidwe mu zofunika ofanana. kwa okhutira choyambirira mpweya ndi carbon ❖ kuyanika mbali, kale decarburization zomangira pang`onopang`ono kubwerera ku choyambirira zili mpweya, mphamvu mpweya waikidwa 0.42% 0.48% m'pofunika, nanotubes ndi kuzimitsa kutentha kutentha, yemweyo sangathe pansi pa kutentha kwambiri, pofuna kupewa coarse. mbewu, zimakhudza mawotchi properties.Mavuto apamwamba a zomangira mu kuzimitsa ndi kuzimitsa ndondomeko ndi: kuzimitsa kuuma sikukwanira;Kusaumitsa kuuma kosagwirizana;Kuzimitsa kuphulika kwakukulu;Kuzimitsa kuphulika.Mavuto oterewa m'munda nthawi zambiri amakhudzana ndi zopangira, kuzimitsa kutentha. ndi kuzimitsa kuziziritsa. Kukonzekera koyenera kwa njira yochiritsira kutentha ndi kukhazikika kwa ntchito yopangira ntchito kumatha kupewa ngozi zamtunduwu.
