Ngophuhliso olukhawulezileyo lweshishini leemoto kunye nokuqhubela phambili okuqhubekayo kubuchule bokuvelisa, ii-molds zeemoto ziye zaba zizixhobo ezibalulekileyo zenkqubo kwimveliso yeemoto. Umgangatho wazo kunye nokusebenza kwazo kumisela ngokuthe ngqo ukuchaneka, ubomi, kunye nokusebenza kakuhle kwemveliso yeenxalenye zeemoto. Phakathi kweendlela ezahlukeneyo zokuqinisa umphezulu, ukuqina komphezulu we-laser kuye kwafumana ingqwalasela ebalulekileyo kwiminyaka yakutshanje ngenxa yeenzuzo zayo eziquka uxinano olukhulu lwamandla, ukufudumeza/ukupholisa ngokukhawuleza, ukuguqulwa okuncinci, kunye nobuhlobo nokusingqongileyo. Eli phepha lijolise ekuhloleni ngokucwangcisiweyo usetyenziso lwangoku, imingeni ephambili, kunye neendlela zophuhliso zexesha elizayo zobuchwepheshe bokuqinisa i-laser kwimveliso ye-mold yeemoto.
I. Umgaqo osisiseko kunye neempawu zobuchwepheshe bokucima i-laser
Ukucima i-laser yinkqubo esebenzisa imisebe ye-laser enamandla aphezulu ukufudumeza ngokukhawuleza nokupholisa iindawo zesinyithi, ukufezekisa ukuqina komphezulu ngokuguqula inqanaba. Le teknoloji inommandla omncinci ochaphazeleka bubushushu, ukuguquguquka okuncinci komsebenzi, akukho mfuneko yokupholisa, kunye nokulawula lula ubunzulu kunye nokusasazwa komaleko oqinileyo. Ifanelekile ngokukodwa kwiimolds zezithuthi ezintsonkothileyo ezineemfuno ezichanekileyo eziphezulu, ezifana nee-stamping dies, ii-injection molds, kunye nee-die-casting dies. Kwimveliso yeemolds zezithuthi, ukucima i-laser akupheleli nje ekuphuculeni ubunzima bomphezulu, ukumelana nokuguguleka, kunye namandla okudinwa kweemolds kodwa ikwagcina ngokufanelekileyo ukuqina kwe-substrate yemold, ngaloo ndlela yandisa ubomi benkonzo kwaye inciphise iindleko zokulungisa.
II. Iimeko ezithile zesicelo kwisikhunta seemoto
I-motor mold, ingakumbi i-cover sheet stamping mold enkulu, i-interior part injection molding kunye ne-die casting mold, yeyona ndawo iphambili yokulwa iteknoloji yokucima i-laser ukubonisa amandla ayo.
1. Umphetho ophambili kunye nomphezulu woxinzelelo oluphambili lwe-stamping die ziyaqiniswa
Ii-stamping dies zegobolondo lemoto kunye neendawo zesakhiwo (ezifana neengcango, izigqubuthelo zenjini, kunye nee-longitudinal beams) zinkulu ngobukhulu kwaye zibiza kakhulu. Umphetho ophambili we-trimming die, i-drawing rib ye-drawing die, kunye nekona ye-convex kunye ne-concave die zichaphazeleka kakhulu kwaye zichaphazeleka ngexesha lomsebenzi, ezilula ukuzinxiba.
Isicelo: Ukucima i-laser kusetyenziselwa ukuqinisa iindawo ezibalulekileyo, kudala indawo eqinileyo kumphezulu we-blade enobunzima obufikelela kwi-HRC 58-62. Oku kuphucula kakhulu ukumelana nokuguguleka ngamaxesha amaninzi, kuthintela ngempumelelo ukwaphuka kwe-blade kunye nokuguguleka, ngaloo ndlela kwandisa kakhulu umjikelo wokugcinwa kwesikhunta kunye nobomi benkonzo. Umzekelo, iseti ye-automotive body panel trimming dies ecinyiweyo nge-laser inokwandisa ubomi bayo bokugaya ukusuka kwi-100,000 ukuya kwi-500,000 yeendawo ezifakwe isitampu.
2. Ukumelana nokugqwala komphezulu kunye nokumelana nokudinwa kwe-die cavity kwi-die casting
Umphezulu womngxuma we-aluminium alloy die casting mold efana nomzimba wesilinda yenjini kunye ne-gearbox housing usengozini yokuqhekeka kobushushu (ukuqhekeka), ukulahleka kokunyibilika kunye nokukhukuliseka phantsi kokukhuhla okuphindaphindiweyo kwesinyithi esinyibilikisiweyo kubushushu obuphezulu kunye noxinzelelo oluphezulu.
Isicelo: Ukucima nge-laser imingxunya yesikhunta esenziwa nge-H13 kunye nezinye iintsimbi zesikhunta ezingatshiyo kuphucula kakhulu ubulukhuni bomphezulu obuphezulu, ukumelana nokudinwa kubushushu, kunye nokumelana nokukhukuliseka kwesinyithi esinyibilikisiweyo. Isakhiwo se-martensitic esicociweyo sithintela ngempumelelo ukuqaliswa nokusasazeka kweentanda, sandisa ubomi benkonzo yesikhunta ngokuphindwe ka-1-2 ngelixa sigcina umgangatho wokuphoswa ohambelanayo.
3. Ukuphucula ukumelana nokuguguleka kunye nokusebenza kokunciphisa ukusebenza kwesikhunta senaliti
I-injection mold yezixhobo zeplastiki ezifana nezixhobo zangaphakathi ezizenzekelayo kunye nezibane, izinto ezihambayo ezifana nee-ejector pins, ii-flow channels, ii-sliders kunye neendawo ezingaphakathi ziyaguguleka yiplastiki eqinisiweyo yefayibha yeglasi ixesha elide, nto leyo elula ukukhokelela kubukhulu obukhulu kunye nokuncipha kokugqitywa komphezulu.
Isicelo: Ukucima ezi ndawo nge-laser kuphucula ukumelana nokuguguleka ngelixa kugcina ukuguguleka okuncinci okugcina ukulingana okuchanekileyo kwesikhunta. Umaleko oqinileyo ukwanciphisa ukunamathela kweplastiki, kuphucula ukusebenza kokunciphisa, kunciphisa ukusetyenziswa kweearhente zokukhulula, kwaye kuphucula ukusebenza kakuhle kwemveliso ngomgangatho ophezulu womphezulu.
4. Ukulungiswa kunye nokuhlaziywa kweenkuni kwi-intanethi
Kwizikhunta ezibizayo ezigugileyo okanye ezonakeleyo kwindawo ethile ngenxa yokungasebenzi kakuhle, iindleko zokutshintshwa ziphezulu kakhulu. Ukucima nge-laser kungasetyenziswa njengenkqubo yokugqibela yokulungisa.
Isicelo: Emva kokugqitywa kokulungiswa kwe-laser cladding kunye nolunye ulungiso olongezelelweyo, unyango lokucima i-laser lwenziwa kwindawo yokulungisa kunye nejoyinti yayo, nto leyo enokwenza ukuba ubunzima bendawo yokulungisa kunye ne-matrix bufikelele kwinqanaba elifanayo okanye eliphezulu, ibuyisele ukusebenza kwayo kwenkonzo, ifumane ixabiso eliphantsi kunye nokulungiswa kwakhona kwe-mold esemgangathweni ophezulu, igcine iindleko ezininzi.
III. Iindlela zoPhuhliso lweTekhnoloji kunye namathemba
Ngokuqhubela phambili okuqhubekayo kubuchwepheshe be-laser, iinkqubo zolawulo, kunye nesayensi yezinto, ukucima i-laser kubonisa amandla amakhulu okwenziwa kwesikhunta seemoto kwixesha elizayo. Kwelinye icala, izixhobo zokucubungula i-laser ezinamandla aphezulu ziya kusasazeka ngakumbi, zenze ukuba ukucima umphezulu okukrelekrele nokuzenzekelayo ngokupheleleyo ngokusebenzisa umbono womatshini kunye neenkqubo zokubeka esweni kwi-intanethi. Kwelinye icala, ngokuhlanganisa iinkqubo ze-laser kunye nonyango lokufudumeza kwangaphambili kunye nonyango emva kokufudumeza, imikhwa yokuqhekeka inokucinezelwa ngempumelelo kwizixhobo ezinzima ezifana nentsimbi enekhabhoni ephezulu kunye nesinyithi esityhidiweyo, ngaloo ndlela yandisa uluhlu lwezixhobo ezifanelekileyo. Ngaphezu koko, ukulinganisa inkqubo yokucima ebonakalayo ngokusekelwe kubuchwepheshe bedijithali obuphindwe kabini kuya kunciphisa kakhulu iindleko zovavanyo kwaye kuphucule ukusebenza kakuhle kwenkqubo. Kudityaniswe nedatha enkulu kunye namaqonga efu, ukugcinwa kokusebenza okukude kunye nokwenza ngcono okwabelwana ngako kweenkqubo zokucima i-laser kulindeleke ukuba kube nokwenzeka kwixesha elizayo.
Itekhnoloji yokucima umphezulu welaser iyavela njengesisombululo esibalulekileyo kunyango lobushushu besikhunta seemoto. Njengoko ishishini litshintshela kwimveliso elula nenamandla aphezulu, le ndlela kufuneka ifezekise impumelelo ekuzinzeni kwenkqubo, ukulungelelaniswa kwezinto, kunye neenkqubo zolawulo ezikrelekrele. Ngokudityaniswa okunzulu kwentsebenziswano phakathi kweshishini-imfundo-uphando kunye nentsebenziswano phakathi kwezifundo ezahlukeneyo, itekhnoloji yokucima ilaser iya kudlala indima ebaluleke ngakumbi kwicandelo lesikhunta seemoto, inika inkxaso eqinileyo yokuqhubela phambili uphuhliso olusemgangathweni lweshishini lemveliso yeemoto.
