Ni bangahe uzi kubyerekeye gushakisha？

Inkomoko yingufu za brazing zirashobora kuba imiti yubushyuhe cyangwa ingufu zubushyuhe butaziguye.Ikoresha icyuma gifite aho gishonga kiri munsi yicyibikoresho byo gusudira nkumugurisha.Nyuma yo gushyushya, uwagurishije arashonga, kandi igikorwa cya capillary gisunika uwagurishije mu cyuho kiri hagati y’imikoranire y’urugingo kugira ngo atose hejuru yicyuma cyo gusudira kugirango icyiciro cyamazi nicyiciro gikomeye gitandukane.Interdiffusion hagati yicyiciro kugirango ikore ingingo ifatanye.Kubwibyo, gushakisha ni uburyo bukomeye kandi bwamazi yo gusudira.

1. Ibiranga no gukoresha brazing

Brazing ikoresha umusemburo ufite aho ushonga munsi yicyuma cyibanze nkumugurisha.Iyo ashyushye, uwagurishije arashonga kandi yuzura kandi aguma mu cyuho cyo guhuza ibikorwa no guhanagura hamwe na capillary, mugihe icyuma fatizo kimeze neza, gishingiye kumugurisha wamazi hamwe nigitereko gikomeye Interdiffusion hagati yibikoresho ikora ingingo ifatanye.Brazing ntigira ingaruka nke kumiterere yumubiri nubumashini byibyuma fatizo, guhangayikishwa no gusudira no guhindura ibintu, birashobora gusudira ibyuma bidasa nibitandukaniro rinini mumitungo, birashobora kuzuza icyarimwe icyarimwe, isura yingingo ni nziza kandi ifite isuku, ibikoresho biroroshye, kandi ishoramari ry'umusaruro ni rito.Nyamara, gufatanyirizwa hamwe bifite imbaraga nke no kurwanya ubushyuhe buke.

Porogaramu: Ibikoresho byo gukata Carbide, bits yo gucukura, amakarita yamagare, guhinduranya ubushyuhe, imiyoboro hamwe nibikoresho bitandukanye, nibindi.;mugukora microwave waveguide, umuyoboro wa electron nibikoresho bya elegitoroniki vacuum, gushakisha nuburyo bwonyine bushoboka bwo guhuza.

2.Gukata ibyuma na flux

Icyuma cyuzuza icyuma nicyuma cyuzuza kigize umutwe wogosha, kandi ubwiza bwumutwe wikaraga biterwa nicyuma cyuzuza cyane.Icyuma cyuzuza kigomba kugira aho gishonga gikwiye, amazi meza hamwe nubushobozi bwa caulking, birashobora gukwirakwizwa nicyuma fatizo, kandi bigomba kuba bifite imiterere yubukanishi hamwe nibikoresho bya fiziki na chimique kugirango byuzuze ibisabwa nibikorwa.Ukurikije uburyo butandukanye bwo gushonga bwicyuma cyuzuza ibyuma, gushakisha bishobora kugabanywamo ibyiciro bibiri: gusya byoroshye no gukata cyane.

(1) Gukubita byoroheje.Gukata hamwe no gushonga munsi ya 450 ° C byitwa brazing brazing, kandi icyuma gikunze gukoreshwa cyuzuza ibyuma ni tin lead brazing, ifite amazi meza kandi itwara amashanyarazi kandi ikoreshwa cyane mubicuruzwa bya elegitoroniki, ibikoresho bya moteri nibice byimodoka.Imbaraga zingingo zifatanije ni 60 ~ 140MPa.

(2) Brazing.Gukata hamwe no gushonga hejuru ya 450 ° C byitwa brazing, kandi ibikoresho bisanzwe byo gusya ni umuringa nibikoresho bya feza.Ihuriro hamwe nicyuma cya feza yuzuza ibyuma bifite imbaraga nyinshi, amashanyarazi no kurwanya ruswa, aho gushonga ibyuma byuzuza biri hasi, kandi inzira ni nziza, ariko igiciro cyicyuma cyuzuza ni kinini, kandi gikoreshwa cyane mubudozi ibice hamwe nibisabwa cyane.Gukata cyane bikoreshwa mubyuma n'umuringa bivangwa n'imbaraga nini, hamwe nibikoresho byo gushakisha.Imbaraga zifatanije zingana na 200 ~ 490MPa,

Icyitonderwa: Ubuso bwibibanza byibikoresho bigomba kuba bifite isuku cyane, bityo flux igomba gukoreshwa.Uruhare rwa flux ni ugukuraho umwanda wa oxyde hamwe namavuta hejuru yicyuma cyibanze nicyuma cyuzuza, kurinda ubuso bwihuza bwicyuma cyuzuza nicyuma fatizo okiside, kandi bikongerera amazi ya capillary na capillary fluid icyuma.Ingingo yo gushonga ya flux igomba kuba munsi yicyuma cyuzuza, kandi kwangirika kwibisigisigi bya flux kumyuma fatizo hamwe ningingo bigomba kuba bike.Amashanyarazi asanzwe ni rosin cyangwa zinc chloride yumuti, naho flux isanzwe ni uruvange rwa borax, aside boric na fluor ya alkaline.

Ukurikije amasoko atandukanye yubushyuhe cyangwa uburyo bwo gushyushya brazing irashobora kugabanywamo:flame brazing, induction brazing, gucana itanura, gushiramo dip, kurwanira kurwanya nibindi.Kuberako ubushyuhe bwo gushyuha buri hasi mugihe cyo gushakisha, ntabwo bigira ingaruka nke kumikorere yibikoresho byakazi, kandi ihindagurika ryimyitwarire ya weldment nayo ni nto.Nyamara, imbaraga zifatizo zifatanije muri rusange ni nke, kandi kurwanya ubushyuhe ni bibi.

Uburyo bwo gushyushya Brazing:Amashanyarazi hafi ya yose arashobora gukoreshwa nkubushyuhe bwo gutwika, kandi ukurikije uku gushakisha gushyirwa mubikorwa.

Umuriro ugurumana:gushyushya hamwe na flame ya gaz, ikoreshwa mubyuma bya karubone, ibyuma bitagira umwanda, karbide, ibyuma, umuringa n'umuringa, aluminium na aluminiyumu.

Induction brazing:Gukoresha guhinduranya magnetiki yumurima kugirango ubyare amashanyarazi yatewe mugice cyo kurwanya ubushyuhe bwo gushyushya gusudira, kugirango uburinganire busa bwo gusudira, cyane cyane gushakisha imiyoboro.

Kwibiza:igice cyo gusudira igice cyangwa cyinjijwe rwose muruvange rwumunyu rwashongeshejwe cyangwa uwagurishije ashonga, yishingikirije ku bushyuhe bwibi bitangazamakuru byamazi kugirango agere kubikorwa byo gutwika, birangwa nubushyuhe bwihuse, ubushyuhe bumwe, ihinduka rito ryigice cyo gusudira.

Gukoresha itanura:Abasudira bashyutswe nitanura rirwanya, rishobora kurinda abasudira mukuyungurura cyangwa gukoresha kugabanya cyangwa kwinjiza imyuka.

Mubyongeyeho, hariho kugurisha ibyuma, kurigita kurwanya, gukwirakwiza diffuzione, gushiramo infrarafaride, reaction reaction, brazing electronique, laser laser, nibindi.

Brazing irashobora gukoreshwa mu gusudira ibyuma bya karubone, ibyuma bitagira umwanda, superalloy, aluminium, umuringa nibindi bikoresho byuma, kandi birashobora kandi guhuza ibyuma bidasa, ibyuma nibitari ibyuma.Bikwiranye no gusudira hamwe hamwe nuburemere buto cyangwa gukora mubushyuhe bwicyumba, cyane cyane bikwiranye neza, micro na complexe nyinshi zasizwe.
