Iyo bibumbiye mu rupfu rugenda rutera imbere, igitutu cyakazi, ibintu byihutirwa hamwe nibintu byatangiye bigira ingaruka kubushobozi bwo kubona ibisubizo bihamye bidafite inkari.
Ikibazo: Dukora igikombe muri 304 ibyuma bidafite ingese.Kuri sitasiyo yambere yo gupfa gutera imbere, dushushanya kuri santimetero 0,75.Iyo ngenzuye ubunini bwa butt flange perimeter, irashobora gutandukana na santimetero 0.003 kuva kuruhande rumwe.Buri hit iratandukanye kandi ntabwo igaragara ahantu hamwe.Nabwiwe ko bifite aho bihuriye no gutunganya ibikoresho bibisi, ahari inkombe yinyuma ya spol nkuru.Nigute dushobora kubona igikombe cyimiterere ihoraho idafite crease?
Igisubizo: Ndabona ikibazo cyawe kibaza ibibazo bibiri: icya mbere ni itandukaniro ubona muburyo bwo gushushanya, naho icya kabiri ni isoko yibikoresho nibisobanuro byayo.
Ikibazo cya mbere ni inenge yibanze mugushushanya igikoresho, reka rero tujye hejuru yibanze.Ibihe byo guhindagurika hamwe no guhindagurika mubyimbye ku gikombe cya flanges nyuma yo kurambura byerekana ibikoresho bidahuza bidahagije murwego rwawe rwo gupfa.Utarinze kubona igishushanyo cyawe cyo gupfa, nagira ngo nkeke ko punch no gupfa radii hamwe nibisobanuro byabo byujuje ibipimo bisanzwe.
Mugihe cyo gushushanya, igicapo gifashwe hagati yo gushushanya bipfa no gufata impande, mugihe igishushanyo cyo gushushanya gikurura ibikoresho mugushushanya bipfa, kugikurura kumaradiyo yo gushushanya kugirango gikore igikonoshwa.Ubuvanganzo bukomeye bubaho hagati yububiko hamwe nakazi gafite.Muri iki gikorwa, ibikoresho bikorerwa compression ihindagurika, bikavamo inkari no kurambura imirasire nkuko uwufite inkombe ahagarika gutembera kwibikoresho.Niba igitutu cyo gufunga kiri hejuru cyane, ibikoresho bizacika munsi yingufu zikurura punch.Niba ari hasi cyane, inkinko zizagaragara.
Igikorwa cyo gushushanya cyatsinze ntigishobora kurenga imipaka iri hagati ya shell diameter na diametre yakazi.Iyi mipaka iterwa no kwagura ijanisha ryibikoresho.Amategeko rusange ni ugushushanya 55% kugeza 60% ubwambere na 20% buri gihe nyuma yibyo.Ku mutini.1 yerekana formulaire isanzwe yo kubara umuvuduko wa preform usabwa kugirango urambure (burigihe nongeraho byibuze 30% imbaraga zinyongera nkimpamvu zumutekano. Ibi birashobora kugabanuka nibiba ngombwa, ariko biragoye kwiyongera nyuma yubushakashatsi bwuzuye).
Umuvuduko wa bilet p ni 2.5 N / mm2 kubyuma, 2.0-2.4 N / mm2 kumuringa wumuringa na 1.2-1.5 N / mm2 kuri aluminiyumu.
Itandukaniro mubyimbye bya flange rishobora kandi kwerekana ko igikoresho cyawe kidakomeye bihagije.Inkweto zibumba zigomba kuba zifite umubyimba uhagije kugirango uhangane nimpagarara zitunamye.Inkunga iri munsi yinkweto igomba kuba ifite ibyuma bikomeye, kandi ibiyobora ibikoresho bigomba kuba binini bihagije kugirango birinde urujya n'uruza rw'ibikoresho byo hejuru no hepfo mugihe cyo kurambura.
Reba kandi amakuru yawe.Niba ibiyobora abanyamakuru byambaye kandi birekuye, ntuzabigeraho, nubwo ibikoresho byawe bikomeye.Reba kanda kanda kugirango umenye neza ko ari kare na kare mu burebure bwa kanda.Menya neza ko igishushanyo cyawe cyo gushushanya cyungurujwe kandi kimeze neza, kandi ko igikoresho gikoresha umubare wukuri kandi ugakosora imyanya ya nozzle.Ibikoresho byose byo gucapura bisuzumwa neza kugirango harebwe neza ubuso burangiye, ubwuzuzanye hamwe.Kandi witondere cyane gushushanya radii, bigomba kugira geometrie itunganijwe neza hamwe nisuku yo hejuru.
Na none, mugihe abakiriya bakunda gutekereza ko 304L nibisanzwe 304 bisimburana, 304L nuburyo bwiza bwo kurambura.L igereranya karubone nkeya, itanga 304L 0.2% yumusaruro wa 35 KSI, mugihe 304 ifite 0.2% yumusaruro wa 42 KSI.Hamwe nimbaraga zingana na 16%, 304L isaba imbaraga nke zo guhindura no gufata ifumbire mugihe cyo kubumba.Biroroshye gukoresha.
