Umehluko phakathi umshini wokuqeda imvamisa ephezulu kanye nokususwa kwe-laser

1. Ubuchwepheshe bokucisha i-laser kanye nokusetshenziswa kobuchwepheshe bokucisha i-laser kuyinkqubo yokusebenzisa i-laser beam egxilile ukushisa ngokushesha indawo yensimbi, okubangela ukuba kuguqulwe isigaba futhi kwakhiwe ungqimba oluqinile lwe-martensite. Ukucima i-laser kunamandla amakhulu, isivinini sokupholisa ngokushesha, futhi akudingi imidiya yokupholisa njengamanzi noma uwoyela. Kuwubuchwepheshe bokuhlanza nokucisha ngokushesha. Uma kuqhathaniswa nokucishwa kokungeniswa, ukucisha ilangabi kanye namakhono okucisha i-carburizing, ukucisha i-laser kunongqimba oluqinile olufanayo, ukuqina okuphezulu (imvamisa i-1-3HRC ephakeme kuno-induction quenching), ukuguqulwa kwengcezu encane yokusebenza, ukulawula okulula kokujula kongqimba lokushisa kanye nethrekhi yokushisa, futhi kulula ukuyiqedela. okuzenzakalelayo. Akudingekile ukuklama amakhoyili wokungeniswa ahambisanayo ngokwengxenye yosayizi abahlukene njengokuqiniswa kwe-induction, futhi ukucutshungulwa kwezingxenye ezinkulu akudingi ukukhawulelwa ngosayizi wesithando somlilo ngesikhathi sokwelashwa kokushisa kwamakhemikhali okufana ne-carburizing kanye nokucisha, ngakho-ke ukuqina kwe-induction kancane kancane ishintshwe emikhakheni eminingi yezimboni. nezindlela zendabuko ezifana nokwelashwa kokushisa kwamakhemikhali. Kubaluleke kakhulu ukuthi ukuguqulwa kwe-workpiece ngaphambi nangemuva kokucisha i-laser kungashaywa indiva, ngakho-ke kulungele ngokukhethekile ukwelapha okungaphezulu kwezingxenye ezidinga ukunemba okuphezulu.

2. Ukujula komshini wokucisha i-high-frequency quenching kuhlukile ngokusho kokwakheka, ubukhulu kanye nokuma kwezingxenye kanye nemingcele yobuchwepheshe be-laser, ngokuvamile phakathi kuka-0.3 no-2.0 mm. Ukucisha izindawo zamazinyo zamagiya amakhulu kanye namajenali ezingxenye ezinkulu ze-shaft, ubukhulu obungaphezulu abushintshile, futhi izidingo zezimo zokusebenza ezingokoqobo zinganeliswa ngaphandle kokwenziwa ngomshini okulandelayo. Ubuchwepheshe bokuncibilika kanye nokucisha i-laser kuyinqubo yobuchwepheshe lapho ingaphezulu le-substrate lishiselwa khona libe ngaphezu kwezinga lokushisa elincibilikayo ngogongolo lwe-laser, futhi ubuso bongqimba obuncibilikisiwe bupholiswa ngokushesha futhi bucwebezeliswe ngenxa yokuqhutshwa kwe-thermal nokupholisa ngaphakathi kwe-substrate. . Ilungiselelo elitholiwe lokucisha ukuhlanganisa lihle kakhulu, futhi ilungiselelo elihambisana nokujula liwungqimba oluncibilikayo, ungqimba oluqinile lokushintsha kwesigaba, indawo ethinteke ukushisa kanye ne-substrate.

1. Uma kuqhathaniswa nesendlalelo sokucisha i-laser, umshini wokucisha imvamisa ephezulu unokujula kokuqina okujulile, ubulukhuni obuphakeme kanye nokumelana nokugqokwa okuhle kakhulu. Umshini wokucisha ama-high-frequency usetshenziswe ngempumelelo ukuqinisa ukubukeka kokugqoka izingxenye embonini ye-metallurgical, imboni yemishini kanye nemboni ye-petrochemical, ikakhulukazi ekuthuthukiseni impilo yesevisi yokugqoka izingxenye ezifana nemiqulu, iziqondiso, amagiya, ama-shearing blades, njll. Ngokuphawulekayo, izinzuzo ezinkulu zezomnotho nezenhlalo ziye zafinyelelwa. Eminyakeni yamuva nje, iye yasetshenziswa kabanzi futhi kabanzi ekuqiniseni ukubukeka kwezingxenye ezifana nezibungu namagiya.
