Indlela yokusika insimbi?

Isinyathelo sokuqala sokucutshungulwa kwensimbi ukusika, okubandakanya ukumane uhlukanise izinto ezingavuthiwe noma ukuzihlukanisa zibe izimo ukuze uthole izikhala ezingenalutho. Izindlela ezivamile zokusika insimbi zihlanganisa: ukusika isondo lokugaya, ukusika i-saw, ukusika amalangabi, ukusika i-plasma, ukusika kwe-laser, nokusika i-waterjet.
Ukusika isondo lokugaya
Le ndlela isebenzisa isondo lokugaya eligijima ngesivinini esikhulu ukusika insimbi. Kuyindlela yokusika esetshenziswa kakhulu. Izisiki zamasondo okugaya azisindi, ziyagobeka, zilula, futhi zisebenziseka kalula, okuzenza zamukelwe kabanzi kuzilungiselelo ezahlukahlukene, ikakhulukazi ezindaweni zokwakha kanye namaphrojekthi okuhlobisa angaphakathi. Ngokuyinhloko asetshenziselwa ukusika amashubhu ayisikwele anobubanzi obuncane, amashubhu ayindilinga, namashubhu anomumo ongajwayelekile.

I-Saw cutting
Ukusika amasaha kubhekisela endleleni yokuhlukanisa izinto zokusebenza noma izinto zokwakha ngokusika izikhala eziwumngcingo usebenzisa i-saw blade (isaw disc). Ukusika ama-saw kwenziwa kusetshenziswa umshini wokusaha wensimbi. Izinto zokusika zingenye yezidingo eziyisisekelo kakhulu ekusetshenzisweni kwensimbi, ngakho-ke saw imishini iyimishini ejwayelekile embonini yemishini. Phakathi nenqubo yokusika, i-saw blade efanelekile kufanele ikhethwe ngokusekelwe ebukhuni bezinto ezibonakalayo, futhi isivinini sokusika esifanele kufanele silungiswe.

I-Flame Cutting (I-Oxy-fuel Cutting)
Ukusika ilangabi kuhlanganisa ukushisisa insimbi ngokusabela kwamakhemikhali phakathi kwe-oxygen nensimbi encibilikisiwe, ukuyithambisa, futhi ekugcineni uyincibilikise. Igesi yokushisisa ngokuvamile i-acetylene noma igesi yemvelo.
Ukusika ilangabi kulungele kuphela amapuleti ensimbi ye-carbon futhi akusebenzi kwezinye izinhlobo zensimbi, njengensimbi engagqwali noma ama-alloys ethusi/aluminium. Izinzuzo zayo zihlanganisa izindleko eziphansi kanye nekhono lokusika izinto ezifika kumamitha amabili ubukhulu. Ukungalungi kufaka phakathi indawo enkulu ethinteke ekushiseni kanye ne-thermal deformation, eneziphambano ezimaholoholo kanye nezinsalela ze-slag.

Ukusika kwePlasma
Ukusika i-Plasma kusebenzisa ukushisa kwe-arc yezinga lokushisa eliphezulu le-plasma ukuze kuncibilike endaweni (futhi kuhwamuke) insimbi emaphethelweni okusika ocezu lokusebenza, futhi kususa insimbi encibilikisiwe kusetshenziswa umfutho we-plasma enesivinini esikhulu ukwenza ukusika. Ngokuvamile isetshenziselwa ukusika izinto ezinobukhulu obufika ku-100 mm. Ngokungafani nokusika amalangabi, ukusika kwe-plasma kuyashesha, ikakhulukazi lapho kusika amashidi amancane ensimbi evamile ye-carbon, futhi indawo enqunyiwe ibushelelezi.

  

Ukusika i-Laser

Ukusika i-laser kusebenzisa i-laser enamandla amakhulu ukushisa, ukuncibilikisa endaweni, kanye nokuhwamisa insimbi ukuze kuzuzwe ukusikwa kwezinto, ngokuvamile okusetshenziselwa ukusikwa okuphumelelayo nokunemba kwamapuleti ensimbi azacile (<30 mm).Ikhwalithi yokusika i-laser yinhle kakhulu, ngakho kokubili isivinini sokusika esiphezulu nokunemba kobukhulu.

 

I-Waterjet Cutting
Ukusika i-Waterjet kuyindlela yokucubungula esebenzisa amajethi amanzi anengcindezi ephezulu ukusika insimbi, ekwazi ukusika ngesikhathi esisodwa kwanoma iyiphi into ehambisana namajika angaqondakali. Njengoba i-medium ingamanzi, inzuzo enkulu kakhulu yokusika i-waterjet yukuthi ukushisa okukhiqizwa ngesikhathi sokusika kuthathwa ngokushesha yi-jet yamanzi esivinini esikhulu, kuqeda imiphumela yokushisa.
