Intambwe ikomeye cyane mukubyara imbaraga-zikomeye

Impamyabumenyi-ikomeye ya bolt yakozwe ninganda zacu harimo metric 8.8, 10.9, 12.9, ASTMUNC Gr5, Ibyiciro 8. Imbuto zifite imbaraga nyinshi zirimo metric 8 na 10, na ANSI icyiciro cya 5 na G8, byose bisaba kuvura ubushyuhe

Kuzimya no gutwarwa bivuga uburyo bwo kuvura ubushyuhe bukoreshwa mugutezimbere ibikoresho byubukorikori. Nyuma yo kuzimya, ikorerwa ubushyuhe bwo hejuru. Ikigamijwe ni ukugera kumurongo mwiza wimbaraga nubukomezi mubice byibyuma, hamwe nimbaraga nyinshi hamwe nubukomere buhebuje, plastike, imikorere yo guca, nibindi. Ibyuma bimwe na bimwe bivanze cyangwa ibyuma bito bito bigomba guhura no kuzimya kugirango ubone ibintu byiza byuzuye, kandi ibyo byuma nabyo bishobora kwitwa ibyuma byazimye kandi bifite ubushyuhe. Nyuma yo kuzimya no kuvura imiti, ibyuma byangiza ntibishobora kongera imbaraga gusa, ahubwo binongera ubukana no kwambara birwanya

Intangiriro
Kuzimya no kuvura bivuga uburyo bubiri bwo kuvura ubushyuhe bwo kuzimya hamwe nubushyuhe bwo hejuru, bugamije gukora igihangano gifite imiterere myiza yubukanishi. Ubushyuhe bwo hejuru bivuga ubushyuhe hagati ya 500-650 ℃. Ibice byinshi byazimye kandi bituje bikora munsi yumutwaro munini ugereranije, ufite ingaruka zo guhagarika umutima, kwikuramo, kunama, torsion, cyangwa kogosha. Ubuso bumwe nabwo bufite ubushyamirane, busaba kwihanganira kwambara, nibindi. Muri make, ibice bikora munsi yibibazo bitandukanye. Ubu bwoko bwibice nibice bigize imiterere yimashini nuburyo butandukanye, nka shaft, guhuza inkoni, bolts, ibikoresho, nibindi. Byakoreshejwe cyane mubikorwa byinganda nkibikoresho byimashini, imodoka, na traktori. Cyane cyane kubice binini mubikorwa byimashini ziremereye, kuzimya no kuvura ubushyuhe bikoreshwa cyane. Kubwibyo, kuvura ubushyuhe bigira uruhare runini mukuvura ubushyuhe. Imikorere isabwa kubice byazimye kandi byoroheje mubicuruzwa bya mashini biratandukanye bitewe nuburyo bahangayitse. Muri rusange, ibice bitandukanye byazimye kandi bifite ubushyuhe bigomba kuba bifite imiterere yubukanishi yuzuye, ni ukuvuga guhuza imbaraga zingirakamaro hamwe no gukomera gukomeye, kugirango ibikorwa byigihe kirekire bikore neza.
Intambwe n'amahame
Kuzimya nintambwe yambere yintambwe, kandi ubushyuhe bwo gushyuha buterwa nibigize ibyuma. Uburyo bwo kuzimya bwatoranijwe bushingiye ku bushobozi bukomeye bw'ibyuma n'ubunini bw'icyuma. Nyuma yo kuzimya, ibyuma bifite ibibazo byimbere imbere kandi biroroshye. Kwiyoroshya birakenewe kugirango ukureho imihangayiko, kongera ubukana, no guhindura imbaraga. Ubushuhe ninzira yingenzi muguhuza imiterere yubukanishi bwicyuma kizimye. Umurongo wibikoresho bitandukanye byubukanishi bihinduka hamwe nubushyuhe bwubushyuhe, bizwi kandi nkubushyuhe bwo kugorora ibyuma, birashobora gukoreshwa nkifatizo ryo guhitamo ubushyuhe bwubushyuhe. Kubushyuhe bwo hejuru bwubushyuhe bumwe na bumwe bwazimye kandi bufite ubushyuhe, hakwiye kwitabwaho kugirango hirindwe ko habaho ubwoko bwa kabiri bwubushyuhe bukabije kugirango ibyuma bikore neza.
Porogaramu
Kuzimya no gutuza bikoreshwa cyane mubice byubaka bisaba imikorere myiza cyane, cyane cyane mugukora munsi yimizigo isimburana, nka shitingi yimodoka na gare, shitingi ya turbine na disiki ya compressor ya moteri yindege, nibindi. Ibice byibyuma byubaka bisaba kuzimya ubushyuhe bwa induction mubisanzwe bizimya kandi bigashyirwa mubikorwa mbere yo kuzimya hejuru kugirango habeho imitungo myiza kandi igahinduka neza. Ibice bya nitride bivura kuzimya no kuvura ubushyuhe mbere ya nitriding birashobora kunoza imikorere yicyuma kandi bigategura imiterere ya nitriding. Kugirango ugere ku buryo bworoshye bwigikoresho cyo gupima mbere yo kuzimya, kura imihangayiko iterwa no gukora imashini ikarishye, kugabanya ihindagurika ryimikorere, no gukora ubukana nyuma yo kuzimya hejuru kandi imwe, kuvura no kuzimya bishobora gukorwa mbere yo gutunganya neza. Kumashanyarazi yibikoresho hamwe na karbide ya neti cyangwa ibinyampeke bito nyuma yo guhimba, kuzimya no kuvura ubushyuhe birashobora gukoreshwa mugukuraho urusobe rwa karbide, gutunganya ibinyampeke, no kunoza imashini mukoresha spheroidizing karbide, gutegura microstructure yo kuvura ubushyuhe bwa nyuma.
Ikoranabuhanga
Uburyo bwo gutunganya ubushyuhe bwibyuma bukubiyemo uburyo nka annealing, bisanzwe, kuzimya, ubushyuhe, hamwe no kuvura ubushyuhe bwo hejuru. Muri byo, ubushyuhe burimo ubushyuhe bwo hejuru, ubushyuhe bwo hagati, na
Ubushyuhe buke. Gushyushya ibyuma byazimye ku bushyuhe runaka hanyuma ukonjesha ukoresheje uburyo runaka byitwa ubushyuhe. Ikigamijwe ni ugukuraho imihangayiko y'imbere iterwa no kuzimya, kugabanya ubukana n'ubugome, no kugera kubiteganijwe

Ibikoresho bya mashini.
Kuzimya no kurakara mubisanzwe bivuga uburyo bwo kuvura ubushyuhe bwo kuzimya hamwe nubushyuhe bwo hejuru kugirango ubone martensite. Uburyo ni ukubanza kuzimya, hamwe n'ubushyuhe bwo kuzimya Ac3 + 30-50 ℃ ibyuma bya hypoeutectoid; Ibyuma bya Eutectoid ni Ac1 + 30 ~ 50 ℃; Amavuta avanze arashobora gutera imbere gato ugereranije nicyuma cya karubone. Nyuma yo kuzimya, ubushyuhe burashobora gukorwa kuri 500-650 ℃.
Icyuma kizimye kandi gifite ubushyuhe
Ibyitwa ibyuma byazimye kandi bifite ubushyuhe muri rusange bivuga ibyuma biciriritse biciriritse bifite karubone ya 0.3-0,6%. Ibice bikozwe muri ubu bwoko bwibyuma bisaba ibintu byiza byubukanishi, ni ukuvuga, gukomeza imbaraga nyinshi mugihe bifite plastike nziza nubukomere. Abantu bakunze gukoresha modulisiyo yo kuvura kugirango bagere kuriyi ntego, abantu rero bakunze kuvuga ubu bwoko bwibyuma nkibyuma bizimye kandi bituje. Twabibutsa ko rimwe na rimwe ibyuma bizimya kandi bikonje nabyo bivuga inzira yo kongeramo manganese na silikoni mugihe cyo gushonga ibyuma, kandi hagomba kwitonderwa itandukaniro.
