Iyini i-Abrasive Waterjet Cutting?

Ukusika i-Waterjet kungenye yezinqubo ezisetshenziswa kakhulu ekukhiqizeni. Kunezinhlobo ezimbili ezihlukene zokusika i-waterjet. Enye i-waterjet cutting ehlanzekile, kanti enye i-abrasive waterjet cutting. Kulesi sihloko, ukusika i-waterjet abrasive kuzokhulunywa ngakho kulezi zici ezilandelayo:

Isingeniso esifushane sokusika kwejethi yamanzi abrasive

Ukusika ijethi yamanzi abrasive kuqondene nezinqubo zezimboni, lapho uzodinga ukusika izinto eziqinile njengengilazi, insimbi, netshe usebenzisa ukucindezela okuphezulu okuvela kumfudlana wejethi oxutshwe namanzi abrasive. Izinto eziqhumayo ezixutshwe namanzi zisiza ukukhuphula isivinini samanzi futhi ngaleyo ndlela, zandise amandla okusika omfudlana wejethi lamanzi. Lokhu kuyinikeza amandla okusika izinto eziqinile.

Abakhiqizi bathola indlela yokusika ijethi yamanzi abrasive ngeminyaka yawo-1980, bathola ukuthi ukufaka ama-abrasive emfudlaneni wamanzi kwakuyindlela enhle yokuthuthukisa umthamo wayo wokusika, futhi lokhu kwaveza uhlu olusha lwezicelo zejethi yamanzi. Amajethi amanzi abrasive alandela izimiso zokusebenza ezifanayo njengamajethi amanzi ahlanzekile, noma kunjalo, inqubo yabo ihluke ngenxa yokwethulwa kwezinhlayiya ezilimazayo njenge-garnet. I-garnet exutshwe nomfudlana wamanzi anengcindezi ephezulu ingaguguleka cishe noma iyiphi into esendleleni yayo ngokunemba nangesivinini.

I-abrasive waterjet cutting isebenza kanjani?

I-abrasive material ihlangana namanzi bese iphuma ngesivinini esikhulu ukuze isike into oyifunayo. Ezimweni eziningi, isihlabathi se-olive nesihlabathi se-garnet sisetshenziswa njengezinto eziqhumayo. Uma izinto zokusika zithambile, i-corundum isetshenziswa njenge-abrasive.

Ukusika i-waterjet e-abrasive kusebenzisa inhlayiya e-abrasive (isb. i-garnet) engezwe emanzini anomfutho ophezulu ukusika izinto eziqinile. I-particle abrasive yengezwa emanzini ku-nozzle yomshini wokusika amanzi we-waterjet. Kulo msebenzi, yizinhlayiyana eziqhumayo ezenza umsebenzi wokusika izinto. Indima yamanzi ukusheshisa i-particle abrasive kuze kube yijubane elifanele ukusika nokuqondisa izinhlayiya endaweni ekhethiwe yokusika. I-nozzle egxilile egxilile kanye negumbi lokuxubha elilumayo lingasetshenziswa ekusikeni kwejethi yamanzi abrasive.

Izici ze-abrasive waterjet cutting

Umshini wokusika ijethi yamanzi abrasive mkhulu ngo-0.2mm kunomshini wejethi wamanzi ojwayelekile ngokwesilinganiso. Ngomshini wokusika ijethi yamanzi abrasive, ungakwazi ukusika insimbi kuze kufike ku-50 mm kanye no-120 mm wezinye izinsimbi.

Kukhona futhi amakhanda okusika emakethe lapho izingxenye ezimbili, i-orifice ne-mixing chamber, zifakwe unomphela. Lawa makhanda kubiza kakhulu ukusebenza ngoba kufanele ashintshwe aphelele ngokushesha nje lapho enye yezingxenye isigugile.

Ukusetshenziswa kwe-abrasive waterjet cutting

Ukusika ijethi yamanzi e-Abrasive ifanele izinto eziwugqinsi neziqinile, njenge-ceramic, insimbi, ipulasitiki, itshe, nokunye okunjalo.

Izinzuzo ze-abrasive waterjet cutting

· Kuyinto ubuchwepheshe obuluhlaza. Ngesikhathi sokusika, ayishiyi ngemuva noma iyiphi imfucuza eyingozi.

· Ivumela ukugaywa kabusha kwezinsimbi ezilahliwe.

· The close loop system ivumela inqubo isebenzisa amanzi amancane kakhulu.

· Ingakwazi ukusika izinto ezihlukahlukene. Uma iqhathaniswa nejethi lamanzi elihlanzekile nezinye izisiki, iyakwazi ukuphatha cishe noma iyiphi into esukela engilazini engangenwa izinhlamvu kuya kumatshe, izinsimbi, noma izinto zokwakha ezinendawo ekhanyayo noma engalingani.

· Ikhiqiza ukushisa okuncane noma akukho nhlobo. Inqubo yokusika ikhiqiza ukushisa okuncane kakhulu, ngakho-ke izinto ezibucayi zihlala zinjalo futhi usengozini.

· Inembe kakhulu. Umsiki uyakwazi ukwenza ukunemba okuphezuluukusika noma ukuqopha izimo ezi-3-D.

· Iwusizo kakhulu emigodini yokubhoboza noma izimo eziyinkimbinkimbi.

· Ingasebenza emigodini okungangeneki kuyo ngezinye izindlela.

Izinselelo zokusika ijethi yamanzi abrasive

· Kuzobiza isikhathi eside sokusika. Yize umsiki wejethi wamanzi abrasive ekwazi ukusika izinto eziningi, kuthatha isikhathi eside ukwenza kanjalo, ngaleyo ndlela kunqande ukuphuma.

· Amabhomu antekenteke futhi aphila isikhathi esifushane.

· Ukwehluleka Komshini ngenxa yezinga eliphansi lemisele yejethi yamanzi nezinye izingxenye, okubangela ukuma kokukhiqiza.

· Ngezinto eziwugqinsi, ukungaguquguquki komthelela wejethi lamanzi kunciphisa nebanga lawo ukusuka ku-nozzle, okubangela ukwehla kokunemba kokusikwa.

· Inezindleko zokuqala eziphezulu. Inqubo yokusika ingase ibe nenguquko, kodwa idinga amandla amaningi ukuqalisa.

· Izinto eziqhumayo zibiza kakhulu futhi ngeke ziphinde zisetshenziswe. Inqubo yokusika ijethi yamanzi abrasive ayifanele ukusebenza ngezinto ezithambile njengoba i-abrasive ingase ibambelele kucezu lokusebenza.

Uma unentshisekelo kusisiki se-tungsten carbide waterjet futhi ufuna ulwazi olwengeziwe nemininingwane, UNGASITHINTA ngocingo noma ngemeyili kwesokunxele, noma SITHUMELE I-MEyili ezansi ekhasini.
