Ibikoresho bikoreshwa mu ndoboro
Wigeze utekereza kubyo ibikoresho bikoreshwa kuriindobo ya excavator? Muri iki kiganiro, tuzaganira kubintu bikoreshwa cyane mu mapine, impande, guca impande, Inzu n'amenyo yinzuki zacumbitsemo.
Amapine ya excavator
Amapine ya excavator isanzwe ikozwe muri Aisi 4130 cyangwa 4140. Aisi 4000 ibyuma ni chrome molybdenum ibyuma. Chromium itezimbere kurwanya ruswa, mugihe Molybdenum nayo itezimbere imbaraga nubushobozi bukomeye.
Umubare wambere, 4, ugereranya amanota yicyuma hamwe nububiko nyamukuru bwayo (muriki gihe, Chromium na Molybdenum). Umubare wa kabiri wa 1 ugereranya ijanisha ryibintu bivuguruye, bivuze kuri 1% chromium na molybdenum (na misa). Imibare ibiri yanyuma ni kwibanda kuri charbon muri 0.01%, bityo Aisi 4130 ifite 0,30% Carbone na AiSi 4140 bafite 0.40%.
Icyuma cyakoreshejwe birashoboka ko cyafashwe no kwinjiza. Iyi gahunda yo kuvura ubushyuhe itanga ubuso bukomeye hamwe no kwambara (58 kugeza 63 Rockwell C) hamwe nubutegetsi bworoshye bwo kunoza uburemere. Menya ko bushing isanzwe ikozwe mubintu bimwe nkibipimi. Amapine amwe ahendutse arashobora gukorwa muri aisi 1045. Iyi ni steel icyuma giciriritse gishobora gukomera.
Indobo yindobo hanyuma ukatema impande
Impande z'indobo n'icyuma ubusanzwe bikozwe mu isahani yinyenzi. Amasomo azwi cyane ni AR360 na AR400. AR 360 ni karubone yo hagati ya alloyeli ibyuma yavuwe kugirango itange icyubahiro cyiza kandi imbaraga nyinshi. AR 400 nayo iravuwe, ariko itanga kwambara imbaraga nimbaraga zitanga umusaruro. Ibimera byombi birakomera kandi bikatirwa kugirango tugere ku miterere y'indobo y'indobo. Nyamuneka menya ko umubare nyuma ya Ar ari brissell gukomera kwicyuma.
Indogobe ya excavator
Inzu yindobo isanzwe ikorwa muri ASTM A572 Icyiciro cya 50 (rimwe na rimwe cyanditse A-572-50), nimbaraga nyinshi zo hasi. Icyuma kibajijwe na Niobium na Vatadium. VaAdium ifasha gukomeza ibyuma. Iki cyiciro cya steel nibyiza kubishishwa byindobo nkuko bitanga imbaraga nziza mugihe upima munsi yibisebe byagereranijwe nka a36. Biroroshye kandi kubisumba.
Amenyo ya excavator
Kugirango tuganire kubyoamenyo yindoboByakozwe, ni ngombwa kumva ko hariho uburyo bubiri bwo gufata amenyo yindobo: guta no kubahiriza. Amenyo yindobo arashobora gukorwa muri aly steel steel hamwe na nikel na molybdenum nkibintu nyamukuru bivuguruyemo. Molybdenum itezimbere ubushobozi n'imbaraga zibyuma kandi birashobora kandi gufasha kugabanya uburyo bumwe bwo gukubita byoroshye. Nickel itezimbere imbaraga, gukomera no gufasha gukumira ibyogangishwa. Bashobora kandi gukorwa mu buryo bwa isothermal bwicyuma cyabaye ubushyuhe bwo kunoza imbaraga zo kurwanya no kugira ingaruka. Amenyo yindobo nayo yakozwe mububiko bwa Alloy, ariko ubwoko bwibyuma biratandukanye nuwabikoze gukora. Guvura ubushyuhe biteza imbere imikorere kandi byongera imbaraga.
Uzamure ubucukuzi bwawe hamwe na Bonovo: ibikoresho byo gucunga amababa
Menya indayarwa itagereranywa yaBonovo, aho umwuga, ubuziranenge, kandi kutabogama guhuza kugirango utange ibikoresho byindobondo byindobo hejuru nibihe byihuse. Indobo yacu yo gucukura irakorwa nibikoresho byiza, kugirango iramba kandi imikorere kubyo ukeneye byose.
Amapine yo gucumbika, yakozwe mu kuvumbura Aisi 4130 cyangwa 4140 icyuma, tanga ibitero bidasanzwe no kurwanira ubushobozi bukomeye. Impande no gukata impande zubatswe kuri AR360 cyangwa ar400, gutanga icyamamare no gufata ingaruka. Ku miyoboro y'indobo, dukoresha ASTM A572 icyicaro cya 50, kizwi ku mbaraga nyinshi na miterere yoroheje. Ubwanyuma, amenyo yindobo yacu yateguwe cyane binyuze mu kwita ku buryo bwo guta cyangwa guhimba, gukoresha ibyuma biri hasi cyangwa isothermal ibwrale ihamye hamwe na ruswa.
Kuri Bonovo, dushyira imbere ibikoresho byicyiciro cyumwuga hamwe nibisubizo bihujwe, byemeza ko bihuta bitabangamiye ku bwiza. Hitamo Bonovo kubikoresho byo gusiganwa byindobo bizamura imishinga yawe yubwubatsi muburebure bushya.
