Ungayisika njani isinyithi?

Inyathelo lokuqala ekucutshungulweni kwesinyithi kukusika, okubandakanya ukunqumla nje izinto ezikrwada okanye ukuzahlula zibe yimilo ukuze kufunyanwe iindawo ezingenanto. Iindlela eziqhelekileyo zokusika isinyithi ziquka: ukusika amavili okusila, ukusika isarha, ukusika ilangatye, ukusika iplasma, ukusika nge-laser, kunye nokusika i-waterjet.
Ukusika amavili okusila
Le ndlela isebenzisa ivili lokusila elijikelezayo ngesantya esiphezulu ukusika intsimbi. Yindlela yokusika esetyenziswa kakhulu. Izicucu zamavili okusila zilula, ziguquguquka, zilula, kwaye zilula ukuzisebenzisa, nto leyo eyenza ukuba zisetyenziswe kakhulu kwiindawo ezahlukeneyo, ingakumbi kwiindawo zokwakha nakwiiprojekthi zokuhombisa ngaphakathi. Zisetyenziswa kakhulu ekusikeni iityhubhu zesikwere ezincinci, iityhubhu ezijikelezileyo, kunye neetyhubhu ezimile ngendlela engacwangciswanga.

Ukusika isarha
Ukusika isarha kubhekisa kwindlela yokwahlulahlula izinto zokusebenza okanye izinto ngokusika izithuba ezimxinwa kusetyenziswa i-saw blade (idiski yesarha). Ukusika isarha kwenziwa kusetyenziswa umatshini wesarha webhendi yesinyithi. Izinto zokusika zezinye zezona mfuno zisisiseko ekucutshungulweni kwesinyithi, ngoko ke saOomatshini be-w zizixhobo eziqhelekileyo kushishino loomatshini. Ngexesha lenkqubo yokusarha, kufuneka kukhethwe i-saw blade efanelekileyo ngokusekelwe kubunzima bezinto, kwaye isantya sokusika esifanelekileyo kufuneka silungiswe.

Ukusika Ilangatye (Ukusika i-oxy-fuel)
Ukusikwa kwedangatye kubandakanya ukufudumeza isinyithi ngokusebenzisa i-chemical reaction phakathi kwe-oksijini nentsimbi enyibilikisiweyo, ukuyithambisa, kwaye ekugqibeleni iyinyibilikise. Igesi yokufudumeza idla ngokuba yi-acetylene okanye igesi yendalo.
Ukusika ilangatye kulungele kuphela iipleyiti zesinyithi sekhabhoni kwaye akusebenzi kwezinye iintlobo zesinyithi, njengentsimbi engatyiwayo okanye i-alloys yobhedu/i-aluminium. Iingenelo zalo ziquka ixabiso eliphantsi kunye nokukwazi ukusika izinto ukuya kuthi ga kwiimitha ezimbini ubukhulu. Iingxaki ziquka indawo enkulu echaphazeleka bubushushu kunye nokuguquguquka kobushushu, kunye namacandelo angqukuva kunye neentsalela ze-slag ezihlala zikho.

Ukusika ngePlasma
Ukusika i-plasma kusebenzisa ubushushu be-plasma arc yobushushu obuphezulu ukunyibilikisa isinyithi kwindawo ethile (nokusitshisa) kwindawo ethile kwindawo yokusika yesixhobo somsebenzi, kwaye kususwe isinyithi esinyibilikisiweyo kusetyenziswa amandla e-plasma ekhawulezayo ukwenza ukusika. Ngokuqhelekileyo isetyenziselwa ukusika izinto ezinobukhulu obufikelela kwi-100 mm. Ngokungafaniyo nokusika ilangatye, ukusika i-plasma kukhawuleza, ingakumbi xa kunqunyulwa amaphepha amancinci esinyithi sekhabhoni esiqhelekileyo, kwaye umphezulu osikiweyo uthambile.

  

Ukusika nge-laser

Ukusika nge-laser kusebenzisa umqadi we-laser onamandla aphezulu ukufudumeza, ukunyibilikisa kwindawo ethile, kunye nokwenza isinyithi sibe ngumphunga ukuze kufezekiswe ukusika izinto, okuqhele ukusetyenziselwa ukusika iipleyiti zesinyithi ezibhityileyo nezincinci ngokufanelekileyo (<30 mm).Umgangatho wokusika nge-laser ugqwesile, ngesantya esiphezulu sokusika kunye nokuchaneka okulinganayo.

 

Ukusika iWaterjet
Ukusika iWaterjet yindlela yokucubungula esebenzisa iijethi zamanzi ezinoxinzelelo oluphezulu ukusika isinyithi, ezikwaziyo ukusika kube kanye nayiphi na into ngendlela engaqhelekanga. Ekubeni i-medium ingamanzi, eyona nzuzo inkulu yokusika i-waterjet kukuba ubushushu obuveliswa ngexesha lokusika buthwalwa ngoko nangoko yijethi yamanzi ekhawulezayo, nto leyo esusa iziphumo zobushushu.
