Impamvu n'ibisubizo by'ibura ry'imashini zikoresha hydraulic Press Mold

Iyi ngingo igaragaza ahanini impamvu zatumye habaho gutsindwa kwaimashini isohora amaziibibumbano n'ibisubizo.

1. Ibikoresho byo mu bwoko bwa foromaje

Ibyuma by'ibihumyo ni iby'icyuma cy'ubutare. Hari inenge nko gushyiramo ibintu bitari iby'icyuma, gutandukanya karubide, imyenge yo hagati n'utudomo tw'umweru mu miterere yabyo, bigabanya cyane imbaraga, ubukana n'ubushyuhe bw'ibihumyo. Muri rusange, bigabanyijemo ibihumyo bisanzwe n'iby'ubuziranenge bitewe n'ubwiza bwabyo. Bitewe n'ikoranabuhanga rigezweho mu gukora, ibihumyo byiza ni byiza, bifite imiterere imwe, ni bito mu gutandukanya, kandi bifite ubukana bwinshi n'ubushyuhe.

Umuti: Gucura ibumba risanzwe kugira ngo rimene ibintu binini bitari ibyuma, rikureho gutandukanya karubide, ritunganye karubide, kandi rigatuma imiterere ingana kugira ngo rigere ku ngaruka nziza z'ibumba.

2. Igishushanyo mbonera cy'ibimera

Mu gushushanya ibumba, ingano z'inyuma za module zigomba kugenwa hakurikijwe ibikoresho n'ingano ya geometrike by'igice cyakozwe kugira ngo hamenyekane imbaraga za ibumba. Byongeye kandi, mu gihe cyo gushyushya no gukoresha ibumba, bitewe n'uburebure buto bw'ibumba, igice kinini cy'urukuta rugufi, itandukaniro rinini ry'ubugari bw'urukuta, n'aho umwobo n'umwanya biherereye bidakwiye, biroroshye gutera stress nyinshi no gutangira kwangirika. Igishushanyo mbonera cy'ibumba kigomba kwirinda inguni zityaye uko bishoboka kose, kandi aho umwobo n'aho ushyirwa hagomba gutegurwa neza.

3. Uburyo bwo gukora

1) Uburyo bwo gucura

Iyi fold irimo ibintu byinshi bya alloy, ifite ubushobozi bwo kudahinduka cyane mu gihe cyo gucura, ubushobozi bwo gutwara ubushyuhe buke, n'ubushyuhe buke bwo mu mazi. Iyo utitayeho, bizatera ipfundo ry'ifold. Igomba gushyuha kuri 800-900℃ hanyuma igashyuha kuri 1065-1175℃. Kugira ngo ukureho ibintu binini bitari ibyuma, gukuraho gutandukanya carbide, no gutunganya carbide, gukurura no gukurura bigomba gusubirwamo mu gihe cyo gucura hakoreshejwe uburyo bumwe. Mu gihe cyo gukonjesha nyuma yo gucura, kuzimya imfu zikunze kugaragara. Biroroshye gukora imfu zinyura hagati. Gukonjesha buhoro nyuma yo gukonjesha buhoro nyuma yo gukonjeshagucuraishobora kwirinda iki kibazo.

2) Gukata

Ubukana bw'ubuso bw'igikorwa cyo gukata bugira ingaruka zikomeye ku mikorere y'ubukana bw'ubushyuhe bw'ibumba. Ubukana bw'ubuso bw'ibumba ni buke, kandi nta nenge nk'imihoro, iminkanyari, n'udusimba bihari, ibyo bigatuma habaho stress nyinshi kandi bigatuma ubukana bw'ubushyuhe butangira.
Umuti: Mu gihe utunganya ifumbire, wirinde ko ibimenyetso by'icyuma bisigara ku mfuruka z'ibice bigoye. Kandi ukate uduce tw'imigozi ku myobo, impande z'imirongo n'imizi.

3) Gusya

Mu gihe cyo gusya, ubushyuhe bwo mu gace bushobora gutera ibibazo nko gushya no kwangirika no gutera imbaraga zisigaye ku buso bwo gusya, bigatera ibumba gucika vuba. Gushya guterwa n'ubushyuhe bwo gusya bishobora gukonjesha ubuso bw'ibumba kugeza igihe martensite ishyushye ikorewe. Urusobe rwa martensite rudashyuha kandi rudashyushye ruzagabanya cyane imikorere y'ubushyuhe bw'ibumba. Iyo ubushyuhe bwo mu gace bwo gusya burenze 800°C, kandi ubukonje budahagije, ibikoresho byo hejuru bizongera guhindurwamo imbaraga hanyuma bigashyirwamo martensite. Ubuso bw'ibumba buzakora imbaraga nyinshi mu miterere. Izamuka ry'ubushyuhe bw'ubuso bw'ibumba rizatuma habaho imbaraga zishyushye mu gihe cyo gusya, kandi gushyiramo imbaraga zihagije mu miterere n'ubushyuhe bishobora gutuma ibumba ricikamo ibice byo mu bwoko bw'ibumba.

4) Imitako ya Electropark

Gutunganya Electrospark ni uburyo bw'ingenzi bwo kurangiza mu buryo bugezweho bwo gukora ibumba. Iyo ibumba risohotse, ubushyuhe bw'ako kanya burenga 1000°C, bityo icyuma kiri aho gisohoka kirashonga kikamera nk'umukungugu. Hari urwego ruto rw'icyuma cyashongeshejwe kandi gikonje ku buso bw'ibumba rikoresha electrospark. Harimo uduce twinshi duto. Uru rwego ruto rw'icyuma ni umweru wera cyane. Munsi y'umutwaro w'ibumba, utwo duce duto tworoshye gukuramo uduce duto, bigatuma ibumba rivunika vuba kandi rigashira.
Umuti: Nyuma yo gukora EDM, ifu irakonjeshwa kugira ngo ikureho stress imbere. Ariko, ubushyuhe bwo gukonjesha ntibugomba kurenza ubushyuhe ntarengwa bwo gukonjesha mbere ya EDM.

5) Uburyo bwo gutunganya ubushyuhe

Uburyo bwo gutunganya ubushyuhe bukwiye bushobora gutuma ifumbire ibona imiterere ikenewe ya mekanike no kunoza igihe cyo kuyikoresha. Iyo imiterere cyangwa imikorere yayo idahwitse kandi igatuma ifumbire inanirwa, byangiza cyane ubushobozi bwo gutwara ifumbire, bigatuma ifumbire inanirwa vuba kandi igatuma igihe cyo kuyikoresha kigabanuka. Inenge zo gutunganya ubushyuhe zirimo gushyuha cyane, gutwika cyane, gusiba, gucikamo uduce duto, gukomera kudahagije, nibindi. Nyuma yigihe cyo kuyikoresha, iyo imbaraga z'imbere zirundanyije zigeze ku rugero ruteje akaga, hagomba gukorwa uburyo bwo kugabanya stress no kuyigabanya. Bitabaye ibyo, ifumbire izacika bitewe n'imbaraga z'imbere iyo ikomeje gukoreshwa.

4. Gukoresha ibumba

1) Gushyushya ibumba

Iyi fold ifite ingano nyinshi y’ibintu bya alloy kandi ikaba idakora neza. Igomba gushyushya neza mbere yo kuyikoresha. Iyo ubushyuhe bw’iyi fold buri hejuru cyane mu gihe cyo kuyikoresha, imbaraga zizagabanuka, kandi plastike izahinduka byoroshye, bigatuma ubuso bw’iyi fold bugwa. Iyo ubushyuhe bw’ibanze bushyushye buri hasi cyane, ubushyuhe bw’ubuso buhita buhinduka cyane iyo fold itangiye gukoreshwa, ubushyuhe buba bwinshi, kandi biroroshye kuyicamo.
Umuti: Ubushyuhe bwo gushyushya bwa foromaje bugenwa na 250-300°C. Ibi ntibigabanya gusa itandukaniro ry'ubushyuhe bw'icyuma gishyushya no kwirinda ubushyuhe bwinshi ku buso bw'icyuma gishyushya, ahubwo binagabanya neza ubwihindurize bwa pulasitiki ku buso bw'icyuma gishyushya.

2) Gukonjesha no gusiga amavuta mu ibumba

Kugira ngo bigabanye ubushyuhe bw'ikimera no kwirinda ubushyuhe bwinshi, ikimera gikunze gukonja mu gihe cy'ikimera. Gushyushya no gukonjesha buri gihe ikimera bizatera umunaniro ukabije w'ubushyuhe. Ikimera kigomba gukonjeshwa buhoro buhoro nyuma yo kugikoresha; bitabaye ibyo, ubushyuhe buzagabanuka, bigatuma ikimera gicika kandi kikananirwa.
Umuti: Iyo ibumba rikora, grafiti ishingiye ku mazi ifite 12% bya grafiti irashobora gukoreshwa mu gusiga amavuta kugira ngo igabanye imbaraga zo gukora, kwemeza ko icyuma gitembera neza mu mwobo no koroshya irekurwa ry'icyuma. Amavuta ya grafiti afite kandi ingaruka zo gutwika ubushyuhe, bishobora kugabanya ubushyuhe bw'ibumba.
