Ngaba ukhe wacinga malunga nokuba zeziphi izinto ezisetyenziselwa i-emele ye-excavator?Kule nqaku, siza kuxubusha izinto ezisetyenziswa ngokuqhelekileyo kwizikhonkwane, emacaleni, emacaleni, izindlu kunye namazinyo amabhakethi e-excavator.

Izikhonkwane ze-Excavator

Izikhonkwane ze-Excavator zihlala zenziwe nge-AISI 4130 okanye i-4140 yentsimbi.AISI 4000 series steel yintsimbi chrome molybdenum.I-Chromium iphucula ukunganyangeki komhlwa kunye nokuqina, ngelixa i-molybdenum ikwaphucula amandla kunye nokuqina.

Inombolo yokuqala, i-4, imele ibakala lentsimbi kunye nokwakhiwa kwe-alloy ephambili (kule meko, i-chromium kunye ne-molybdenum).Inombolo yesibini ye-1 imele ipesenti yezinto ezixutywayo, oku kuthetha malunga ne-1% yechromium kunye ne-molybdenum (ngobunzima).Iidijithi ezimbini zokugqibela ziyi-carbon concentrations kwi-0.01% increments, ngoko i-AISI 4130 ine-0.30% ye-carbon kunye ne-AISI 4140 ine-0.40%.

Intsimbi esetyenzisiweyo mhlawumbi iphathwe ngokuqiniswa kwe-induction.Le nkqubo yonyango lobushushu ivelisa ubuso obunzima kunye nokumelana nokunxiba (58 ukuya kwi-63 Rockwell C) kunye ne-malleable yangaphakathi yokuphucula ukuqina.Qaphela ukuba ii-bushings zihlala zenziwe ngezinto ezifanayo njengezikhonkwane.Ezinye izikhonkwane zexabiso eliphantsi zingenziwa kwi-AISI 1045. Le yintsimbi yekhabhoni ephakathi enokuqina.

Amacala eBhakethi ye-Excavator kunye neMiphetho yokusika

Amacala ebhakethi kunye ne-blade ahlala enziwe ngepleyiti ye-AR.Ezona klasi zidumileyo yi-AR360 kunye ne-AR400.I-AR 360 yintsimbi ephakathi kwekhabhoni ephantsi yealloy ethe yaphathwa ubushushu ukuze ibonelele ngokugqwesileyo ukuxhathisa kunye namandla anempembelelo ephezulu.I-AR 400 ikwanyangwa ubushushu, kodwa ibonelela ngokumelana nokunxiba kunye namandla aphezulu esivuno.Zombini iintsimbi ziqiniswe ngononophelo kwaye zihlanjululwe ukufezekisa umgangatho obalulekileyo wemveliso yebhakethi.Nceda uqaphele ukuba inombolo emva kwe-AR yi-Brinell ubulukhuni bentsimbi.

Excavator Bucket Shell

Izindlu zebhakethi zivame ukwenziwa kwi-ASTM A572 Grade 50 (ngamanye amaxesha ibhalwe A-572-50), eyi-A high power low low alloy steel.Intsimbi ifakwe i-niobium kunye ne-vanadium.I-Vanadium inceda ukugcina intsimbi yomelele.Eli nqanaba lentsimbi lilungele amaqokobhe eebhakethi njengoko linika amandla abalaseleyo ngelixa linobunzima obungaphantsi kweentsimbi ezinokuthelekiseka njenge-A36.Kwakhona kulula ukuwelda kunye nokubumba.

Excavator Bucket Amazinyo

Ukuze uxoxe ngamazinyo eebhakethi enziwe ngawo, kubalulekile ukuqonda ukuba kukho iindlela ezimbini zokwenza amazinyo ebhakethi: ukuphosa kunye nokukhwabanisa.Amazinyo ebhakethi ephosiweyo angenziwa ngentsimbi ephantsi ye-alloy kunye ne-nickel kunye ne-molybdenum njengezona zinto ziphambili zokudibanisa.I-Molybdenum iphucula ukuqina kunye nokomelela kwentsimbi kwaye inokunceda ekunciphiseni ezinye iindlela zokubola kwemigodi.I-Nickel iphucula amandla, ukuqina kwaye inceda ukuthintela ukubola.Zisenokwenziwa nge-isothermal quenched ductile iron eye yaphathwa ubushushu ukuphucula ukuxhathisa ukunxiba kunye namandla empembelelo.Amazinyo ebhakethi enziweyo ayenziwe ngentsimbi ye-alloy ephethwe ngubushushu, kodwa uhlobo lwentsimbi luyahluka ukusuka kumenzi ukuya kumenzi.Ukunyanga ukushisa kuphucula ukusebenza kokunxiba kunye nokwandisa amandla empembelelo.

Ukuqukumbela

Iibhakethi ze-excavator zenziwe ngezinto ezininzi ezahlukeneyo, kodwa zonke ezi zixhobo ziyintsimbi okanye uhlobo lwentsimbi.Uhlobo lwezinto eziphathekayo lukhethwa ngokwendlela inxalenye elayishwa ngayo kwaye yenziwe.
