Ibisubizo kuri Shrinkage Byuzuye muri Aluminium Umwirondoro

Ingingo ya 1: Intangiriro kubibazo bisanzwe hamwe no kugabanuka mugihe cyo gukuramo ibicuruzwa:

Mubikorwa byo gukuramo imyirondoro ya aluminium, inenge zikunze kwitwa kugabanuka zizagaragara mugicuruzwa cyarangije gukorwa nyuma yo guca umutwe numurizo nyuma yo kugenzura alkali. Imiterere yubukorikori bwa aluminiyumu ikubiyemo iyi miterere ntabwo yujuje ibisabwa, bigatera umutekano muke.

Muri icyo gihe, iyo imyirondoro ya aluminiyumu yakozwe ikorerwa hejuru yubutaka cyangwa gutunganyirizwa hamwe, kubaho kwiyi nenge byangiza ubudahangarwa bwimbere bwibikoresho, bizagira ingaruka kubutaka bukurikira no kurangiza. Mubihe bikomeye, bizatera ibimenyetso byihishe gusibwa cyangwa kwangirika kubikoresho bihinduka nibindi byago, iki nikibazo gikunze kugaragara mubikorwa. Hano, iyi ngingo irasesengura muri make impamvu zitera gushiraho umwirondoro wa aluminium nuburyo bwo kubikuraho.

Ingingo ya 2: Itondekanya ryo kugabanuka mumashusho ya aluminiyumu yakozwe na extruders: kugabanuka kwuzuye no kugabanuka kwumwaka:

1) Kugabanuka. Igice cyambukiranya kigaragara nkumwobo ufite impande zikaze cyangwa umwobo wuzuye impande zuzuyemo umwanda. Icyerekezo kirekire ni cone imeze nka cone, isonga ya feri ireba icyerekezo cyicyuma gitemba. Bibaho cyane cyane mu ndege imwe yipfa gupfa, cyane cyane umurizo wa profili zasohotse hamwe na coefficient ntoya, ibicuruzwa binini bya diametre, inkuta zibyibushye, cyangwa gasketi yanditswemo amavuta.

2) Kugabanuka kwumwaka. Kugabanuka kwumwaka kuri buri gicuruzwa cyibicuruzwa birasa.

Impamvu yo gushiraho kugabanuka: Imiterere yubukanishi bwo gushiraho kugabanuka ni uko iyo intambwe ya advection irangiye kandi gasi yo gusohora yegera buhoro buhoro ipfa, gusohora byiyongera kandi bikabyara umuvuduko dN kuruhande rwikibanza cyo gukuramo. Izi mbaraga hamwe nimbaraga zo guteranya dT silinderi, mugihe imbaraga zingana zingana dN silinderi ≥ dT padi yangiritse, icyuma giherereye hafi yikibanza cyasohowe gitemba gisubira inyuma cyuruhande rwinjira hagati yubusa, bikora kugabanuka.

Ingingo ya 3: Ni ubuhe buryo bwo gukuramo butera kugabanuka muri extruder:

1. Ibikoresho bisigara bisigaye bigufi

2. Igikoresho cyo gukuramo kirimo amavuta cyangwa umwanda

3. Ubuso bwa ingot cyangwa ubwoya ntabwo busukuye

4. Uburebure bwibicuruzwa ntibukurikiza amabwiriza

5. Imirongo ya silinderi yo gukuramo ntishobora kwihanganira

6. Umuvuduko wo gukuramo wiyongera gitunguranye.

Ingingo ya 4: Uburyo bwo gukuraho kugabanuka kwakozwe na mashini ya aluminiyumu ningamba zo kugabanya no gukumira kugabanuka:

1. Kurikiza byimazeyo amabwiriza yuburyo bwo guca no gukanda ibirenze, kubona umutwe numurizo, kugumisha umurongo wa silinderi yo gusohora neza, kubuza amavuta yo gusohora amavuta, kugabanya ubushyuhe bwinkoni ya aluminiyumu mbere yo kuyikuramo, kandi ukoreshe gaseke idasanzwe. Hitamo uburebure bwuzuye bwibikoresho bisigaye.

2. Ubuso bwibikoresho byo gukuramo nibiti bya aluminiyumu bigomba kuba bifite isuku

3. Kugenzura kenshi ingano ya silinderi yo gukuramo no gusimbuza ibikoresho bitujuje ibyangombwa

4. Gusohora neza, umuvuduko wo gusohora ugomba gutinda mugihe cyanyuma cyo gusohora, kandi umubyimba usigaye ugomba gusigara uko bikwiye, cyangwa hagomba gukoreshwa uburyo bwo gukuramo ibikoresho bisigaye.

Ingingo ya 5: Kugirango ukureho neza ibintu byo kugabanuka mugihe cyo gukora imashini ya aluminiyumu yerekana imashini, ubunini burenze urugero bwa extruder nabwo bugomba kwitabwaho. Ibikurikira nuburyo buvugwa kubyimbye birenze:

Extruder tonnage (T) Ubunini bwikuramo (mm)

800T ≥15mm 800-1000T ≥18mm

1200T ≥20mm 1600T ≥25mm

2500T ≥30mm 4000T ≥45mm
