Kodi munayamba mwaganizapo za zinthu zomwe zimagwiritsidwa ntchito pofukula chidebe?M'nkhaniyi, tidzakambirana za zipangizo zomwe zimagwiritsidwa ntchito kwambiri pazikhomo, m'mbali, m'mphepete, nyumba ndi mano a zidebe zofukula.

Zikhomo za Excavator

Zikhomo zofukula nthawi zambiri zimapangidwa ndi chitsulo cha AISI 4130 kapena 4140.AISI 4000 mndandanda zitsulo ndi chrome molybdenum chitsulo.Chromium imathandizira kukana dzimbiri ndikuuma, pomwe molybdenum imapangitsanso mphamvu komanso kuuma.

Nambala yoyamba, 4, imayimira kalasi yachitsulo ndi kapangidwe kake ka aloyi (panthawiyi, chromium ndi molybdenum).Nambala yachiwiri 1 imayimira kuchuluka kwa ma alloying, zomwe zikutanthauza pafupifupi 1% chromium ndi molybdenum (ndi misa).Manambala awiri otsiriza ndi carbon concentrations mu 0.01% increments, kotero AISI 4130 ili ndi 0.30% carbon ndi AISI 4140 ili ndi 0.40%.

Chitsulo chomwe chimagwiritsidwa ntchito mwina chathandizidwa ndi induction hardness.Njira yochizira kutentha iyi imapanga malo olimba omwe amatha kukana kuvala (58 mpaka 63 Rockwell C) komanso mkati mwathu kuti mukhale wolimba.Dziwani kuti ma bushings nthawi zambiri amapangidwa ndi zinthu zomwezo ngati zikhomo.Zikhomo zina zotsika mtengo zitha kupangidwa kuchokera ku AISI 1045. Ichi ndi chitsulo chapakati cha carbon chomwe chimatha kuumitsa.

M'mbali mwa Chidebe cha Excavator ndi Dulani M'mphepete

Mbali za ndowa ndi tsamba nthawi zambiri zimapangidwa ndi mbale ya AR.Makalasi otchuka kwambiri ndi AR360 ndi AR400.AR 360 ndi chitsulo chapakatikati cha carbon low alloy chomwe chatenthedwa kuti chipereke kukana kovala bwino komanso kulimba kwambiri.AR 400 imathandizidwanso ndi kutentha, koma imapereka kukana kuvala komanso mphamvu zokolola zapamwamba.Zitsulo zonsezi zimawumitsidwa mosamala komanso zimatenthedwa kuti zikwaniritse zofunikira zachidebe.Chonde dziwani kuti nambala pambuyo pa AR ndi Brinell kuuma kwachitsulo.

Chipolopolo cha Chidebe cha Excavator

Nyumba za ndowa nthawi zambiri zimapangidwa kuchokera ku ASTM A572 Grade 50 (nthawi zina imalembedwa A-572-50), yomwe ndi A high mphamvu low low alloy steel.Chitsulocho chimapangidwa ndi niobium ndi vanadium.Vanadium imathandiza kuti chitsulo chikhale cholimba.Chitsulo ichi ndi chabwino kwa zipolopolo za ndowa chifukwa chimapereka mphamvu zabwino kwambiri pomwe chimalemera zochepa poyerekeza ndi zitsulo zofananira monga A36.Ndiwosavuta kuwotcherera ndi mawonekedwe.

Excavator Chidebe Mano

Kuti tikambirane zomwe mano a ndowa amapangidwira, ndikofunika kumvetsetsa kuti pali njira ziwiri zopangira mano a ndowa: kuponyera ndi kufota.Mano a ndowa amatha kupangidwa ndi chitsulo chochepa cha alloy ndi faifi tambala ndi molybdenum monga zinthu zazikuluzikulu zopangira alloying.Molybdenum imathandizira kulimba ndi kulimba kwachitsulo komanso imathandizira kuchepetsa dzimbiri zamitundu ina.Nickel imawonjezera mphamvu, kulimba komanso imathandizira kupewa dzimbiri.Athanso kupangidwa ndi chitsulo cha isothermal chozimitsidwa cha ductile chomwe chatenthedwa kuti chithandizire kukana kuvala komanso mphamvu.Mano a chidebe chopangira amapangidwanso ndi chitsulo chosungunula kutentha, koma mtundu wachitsulo umasiyana ndi wopanga ndi wopanga.Chithandizo cha kutentha kumawonjezera magwiridwe antchito komanso kumawonjezera mphamvu yamphamvu.

Mapeto

Zidebe zofukula zimapangidwa ndi zinthu zingapo zosiyanasiyana, koma zida zonsezi ndi zachitsulo kapena chitsulo.Mtundu wa zinthu umasankhidwa molingana ndi momwe gawolo limanyamulira ndikupangidwira.
