Isikhunta Sensimbi

Isizinda semboni

Njengemishini eyisisekelo yokukhiqiza izimboni, ukusebenza kwezikhunta zensimbi kuthinta ngqo ukusebenza kahle kokukhiqiza kanye nekhwalithi yomkhiqizo emikhakheni yokukhiqiza izimoto, ukukhiqizwa kwemishini yasekhaya, izinto zikagesi zabathengi, njll. Ezimweni ezijwayelekile zokusetshenziswa ezifana nokunyathela, ukubumba ngomjovo, kanye nokubumba ngomshini wokufafaza, izikhunta zibhekana nezimo zokushisa eziphakeme ezingama-300-800℃, imithwalo yokucindezela ephezulu engama-500-2000MPa, kanye nemithwalo yokuthinta izikhathi eziningi ngomzuzu isikhathi eside. Ikakhulukazi, izikhunta zokunyathela zezingxenye zesembozo sezimoto zidinga ukumelana namandla okuthinta angaphezu kwama-2000kN. Izimo ezinjalo zokusebenza ezinzima ziholela ezinkingeni ezivamile zokwehluleka njengokuqhekeka kwemiphetho yokusika isikhunta, ukudilika kwezindawo zokuhlukanisa isikhunta ngomjovo, kanye nokuqhekeka kwemigodi yesikhunta ekhipha ngomshini wokufafaza. Phakathi kwazo, ukugoba kwemingcele yezinto ezisanhlamvu okubangelwa ukushisa okuphezulu kanye nokugqwala ngomshini wokufafaza kungafinyeza impilo yesikhunta. Uma sithatha i-aluminium alloy die-casting njengesibonelo, lapho isikhunta sihlanzwa ngokuphindaphindiwe ngoketshezi lwe-aluminium oluyi-670℃, isilinganiso sengqimba yokugqwala engu-0.2-0.5mm sizokhiqizwa ebusweni bomgodi njalo ngesikhunta esingu-5000.

Izixazululo

Ukumbozwa nge-laser kanye nokwakhiwa kabusha

I-laser yefayibha isetshenziswa kanye nohlelo lokudla lwe-coaxial powder ukulungiselela ungqimba lwe-alloy olusekelwe ku-cobalt (Stellite 6) noma olusekelwe ku-nickel (Inconel 625) oluyi-0.3-1.2mm oluyi-alloy ebusweni besikhunta. Ukuze kube nomkhawulo wokusika wedayi yokunyathela, isakhiwo esihlanganisiwe sengqimba engezansi kanye nengqimba engagugi ebusweni kufezwa ngobuchwepheshe bokumboza i-gradient, okwandisa ubulukhuni bomphetho wokusika kusuka ku-HRC52 kuya ku-HRC62 futhi kuthuthukise ukuqina.

Ukucima nge-laser

Indawo yokusebenza kanye nendawo yokuxhumana yesikhunta kuyacinywa kancane ukuze kwandiswe ubulukhuni, bese kwakheka ungqimba oluqinile oluyi-0.2-0.8mm endaweni yokusebenza yesikhunta. Isebenza kahle kakhulu, i-deformation encane, ayidingi ukucutshungulwa kwesibili, futhi igcina umjikelezo wokucubungula kanye nokusetshenziswa kwamandla okwelashwa kokushisa.
