Kawirikawiri, bawuti mutu aumbike ndi 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 kapamwamba yaitali kapena kulemera ndi 1900-2000 makilogalamu kukula kwa waya ndodo zitsulo waya, processing. ukadaulo ndi mawonekedwe amutu wozizira kupanga si pepala lodulidwa lopanda kanthu pasadakhale, koma AMAGWIRITSA NTCHITO makina ozizira okhawo ndi bar ndi waya ndodo yachitsulokudula ndi kusokoneza chopanda kanthu (ngati n'koyenera). Pamaso pa zotsekera extrusion, chopanda kanthu ayenera reshaped. Chosowekacho chingapezeke mwa kupanga. Chopandacho sichifuna kupanga chisanakhumudwitse, kuchepetsa m'mimba mwake ndi kukanikiza. imatumizidwa ku siteshoni yosokoneza ntchito. Siteshoni iyi ikhoza kupititsa patsogolo ubwino wa malo opanda kanthu, kuchepetsa kupanga mphamvu ya siteshoni yotsatira ndi 15-17%, ndikuwonjezera moyo wa nkhungu. Kusankhidwa kwa njira yopangira ndi ndondomeko yomwe imagwiritsidwa ntchito.Kuonjezera apo, zimadaliranso mawonekedwe a zipangizo zomwe zimagwiritsidwa ntchito, machitidwe a ndondomeko ndi chikhalidwe chawo, kulondola kwa chida, moyo ndi digiri ya kuvala. ntchito pamwamba roughness wa aloyi zolimba kufa sayenera Ra = 0.2um, pamene ntchito pamwamba roughness wa imfa yotere 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 mu mbale ya ulusi (kufa), ndipo ulusi umapangidwa ndi kukakamiza kwa mbale ya ulusi (kufa). ulusi wa pulasitiki wa ulusi wa screw sunadulidwe, mphamvu imachulukitsidwa, kulondola ndipamwamba ndipo khalidwe ndilofanana. chifukwa zimachepetsedwa ndi kulondola kwa ulusi, kaya zokutira zakuthupi ndi zinthu zina.Kugudubuza (kugudubuza) kukanikiza ulusi ndi njira yopangira mano a ulusi ndi pulasitiki deformation.Ili ndi ulusi wokhala ndi phula lomwelo ndi mawonekedwe a conical a kugudubuza ( Kugubuduza waya mbale) kufa, mbali imodzi kuti extrude cylindrical chipolopolo, mbali ina kupanga kasinthasintha chipolopolo, kugubuduza komaliza kufa pa mawonekedwe conical anasamutsidwa kwa chipolopolo, kuti ulusi forming.Kugudubuza (kupaka) kuthamanga ulusi processing mfundo wamba kuti chiwerengero cha kugubuduza zisinthe si kwambiri, ngati kwambiri, dzuwa ndi otsika, pamwamba pa ulusi mano mosavuta kutulutsa kulekana kapena osokonezeka buckle chodabwitsa. M'malo mwake, ngati chiwerengero cha zipolowe kwambiri. yaing'ono, ulusi awiri n'zosavuta kutaya bwalo, kugubuduza kukakamiza zachilendo kuwonjezeka siteji oyambirira, kuchititsa kufupikitsa kufa life.Zowonongeka wamba ulusi wogudubuza: ena pamwamba ming'alu kapena zokala pa ulusi; .Ngati zolakwikazi zikuchitika mu Ziwerengero zazikulu, zidzapezeka mu gawo lokonzekera.Ngati chiwerengero chochepa cha zolakwikazi chikuchitika, ndondomeko yopangira sidzawona zolakwikazi zidzapita kwa wogwiritsa ntchito, zomwe zimayambitsa vuto.Choncho, nkhani zazikuluzikulu za zinthu zogwirira ntchito ziyenera kufotokozedwa mwachidule kuti ziwongolere zinthu zazikuluzikulu zomwe zikupanga.
Zomangira zamphamvu kwambiri ziyenera kutenthedwa komanso kutenthedwa molingana ndi zofunikira zaukadaulo. Cholinga cha chithandizo cha kutentha ndi kutenthetsa ndikuwongolera zida zonse zamakina a zomangira kuti zigwirizane ndi mphamvu yamphamvu yokhazikika 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, mkulu digiri ya zochita zokha ndi khalidwe labwino la kutentha treatment.Since 1990s, mosalekeza kutentha mankhwala kupanga mzere ndi zoteteza mpweya 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 chakudya - kuyeretsa - kutenthetsa - kuzimitsa - kuyeretsa - kutenthetsa - kuyika utoto pa intaneti, kuwonetsetsa bwino kutentha kwamankhwala. The decarburization of screw thread zidzachititsa kuti chomangira chiyende choyamba pamene sichikwaniritsa kukana kwa zofunikira zamakina, zomwe zidzapangitsa kuti screw fastener kutaya mphamvu ndikufupikitsa moyo wautumiki. yaiwisi decarbonization wosanjikiza zakuya.Panthawi yozimitsa ndi kutentha kutentha mankhwala, ena oxidizing mpweya ndi usua.dzimbiri la waya wachitsulo kapena zotsalira pa waya pambuyo pojambula kuzizira zidzawola zikatenthedwa mu ng'anjo, kutulutsa mpweya wotulutsa okosijeni. chitsulo carbonate ndi hydroxide, pambuyo kutentha adzasweka mu CO ₂ ndi H ₂ O, motero aggravating decarburization.Zotsatira zikusonyeza kuti decarburization digiri ya sing'anga mpweya aloyi zitsulo ndi zoopsa kwambiri kuposa mpweya zitsulo, ndi decarburization mofulumira kwambiri. kutentha ndi pakati pa 700 ndi 800 digiri Celsius.
