Wake wacabanga ukuthi yiziphi izinto ezisetshenziselwa ibhakede le-excavator?Kulesi sihloko, sizoxoxa ngezinto ezivame ukusetshenziselwa izikhonkwane, izinhlangothi, imiphetho yokusika, izindlu kanye namazinyo amabhakede e-excavator.

Izikhonkwane ze-Excavator

Izikhonkwane ze-Excavator ngokuvamile zenziwe nge-AISI 4130 noma i-4140 yensimbi.I-AISI 4000 uchungechunge lwensimbi iyinsimbi ye-chrome molybdenum.I-Chromium ithuthukisa ukumelana nokugqwala nokuqina, kuyilapho i-molybdenum iphinde ithuthukise amandla nokuba lukhuni.

Inombolo yokuqala, engu-4, imelela izinga lensimbi kanye nokwakheka kwe-alloy yayo eyinhloko (kulokhu, i-chromium ne-molybdenum).Inombolo yesibili u-1 imele iphesenti lezici ze-alloying, okusho cishe u-1% we-chromium ne-molybdenum (ngesisindo).Izinombolo ezimbili zokugcina ziyi-carbon concentrations ku-0.01% increments, ngakho-ke i-AISI 4130 ino-0.30% we-carbon kanye ne-AISI 4140 ino-0.40%.

Insimbi esetshenzisiwe kungenzeka iphathwe ngokuqiniswa kwe-induction.Le nqubo yokwelapha ukushisa ikhiqiza indawo eqinile enokumelana nokugqokwa (58 kuya ku-63 Rockwell C) kanye nengaphakathi elithambile ukuze kuthuthukiswe ukuqina.Qaphela ukuthi ama-bushings ngokuvamile enziwa ngezinto ezifanayo nezikhonkwane.Amanye amaphinikhodi ashibhile angenziwa nge-AISI 1045. Lena insimbi ye-carbon steel engakwazi ukuqina.

Izinhlangothi Zebhakede Le-Excavator kanye Nemikhawulo Yokusika

Izinhlangothi zamabhakede kanye nensingo ngokuvamile zenziwe ngepuleti le-AR.Amakilasi adume kakhulu yi-AR360 ne-AR400.I-AR 360 iyinsimbi ephansi ye-carbon low alloy eye yaphathwa ngokushisa ukuze inikeze ukumelana nokugqokwa okuhle kakhulu namandla omthelela aphezulu.I-AR 400 iphinde iphathwe ukushisa, kodwa inikeza ukumelana nokugqokwa namandla okukhiqiza aphakeme.Zombili izinsimbi ziqiniswa ngokucophelela futhi zifakwe umoya ukuze kuzuzwe ikhwalithi yomkhiqizo obalulekile webhakede.Sicela uqaphele ukuthi inombolo engemva kwe-AR ingukuqina kwensimbi ye-Brinell.

Igobolondo lebhakede le-Excavator

Izindlu zamabhakede zivame ukwakhiwa kusuka ku-ASTM A572 Grade 50 (ngezinye izikhathi kubhalwe ukuthi A-572-50), okuyi-A high power low alloy steel.Insimbi ihlanganiswe ne-niobium ne-vanadium.I-Vanadium isiza ukugcina insimbi iqinile.Leli banga lensimbi lilungele amagobolondo ebhakede njengoba linikeza amandla amahle kakhulu kuyilapho linesisindo esingaphansi kwezinsimbi eziqhathaniswayo ezifana ne-A36.Kulula futhi ukushisela nokubumba.

Excavator Bucket Amazinyo

Ukuze uxoxe ngokuthi amazinyo ebhakede enziwe ngani, kubalulekile ukuqonda ukuthi kunezindlela ezimbili zokwenza amazinyo ebhakede: ukubunjwa nokubunjwa.Amazinyo ebhakede elikhonjiwe angenziwa ngensimbi ephansi ye-alloy ene-nickel ne-molybdenum njengezakhi eziyinhloko ze-alloying.I-Molybdenum ithuthukisa ukuqina namandla ensimbi futhi ingasiza ekunciphiseni ezinye izinhlobo zokugqwala komgodi.I-Nickel ithuthukisa amandla, ukuqina futhi isiza ukuvimbela ukugqwala.Zingase futhi zenziwe nge-isothermal quenched ductile iron eye yaphathwa ngokushisa ukuze kuthuthukiswe ukumelana nokugqokwa namandla okuthonya.Amazinyo ebhakede akhiwe nawo enziwe ngensimbi ye-alloy ephethwe ukushisa, kodwa uhlobo lwensimbi luyahlukahluka kumkhiqizi kuya kumkhiqizi.Ukwelashwa kokushisa kuthuthukisa ukusebenza kokugqokwa futhi kwandisa amandla omthelela.

Isiphetho

Amabhakede e-Excavator enziwe ngezinto ezihlukahlukene ezihlukahlukene, kodwa zonke lezi zinto zingezensimbi noma uhlobo lwensimbi.Uhlobo lwempahla lukhethwa ngokuya ngokuthi ingxenye ilayishwa futhi yenziwe kanjani.
