Ukuvuselela ubomi bokubumba ngokuvelisa ngobuchule: Ukufakwa kwe-laser kuqala ixesha elitsha lokuvelisa ukubumba okuphucukileyo
Kwishishini lokuvelisa iimoto elikhuphisanayo ngakumbi, imeko yempilo kunye nokusebenza kwee-molds kuqinisekisa ngokuthe ngqo umgangatho weendawo ezifakwe isitampu, ukusebenza kakuhle kwemigca yemveliso, kunye nomgangatho wokugqibela wezithuthi. Ukujongana nokuvalwa nokukhuhla kwee-molds ngenxa yokuguguleka, imikrwelo, kunye nokugqwala, ngaba ujongene nala manqaku alandelayo entlungu?
Ukuveliswa kwesikhunta esitsha kubiza kakhulu kwaye kuthatha ixesha elide?
Ukuwelda kwendabuko kulahlekelwa kukuchaneka kunye nomphezulu orhabaxa, nto leyo efuna ukugaywa ngesandla kakhulu?
Ingaba ubomi bokubumba abunjengoko bekulindelwe kwaye ukutshintshwa rhoqo kukhokelela ekunyukeni kweendleko zemveliso?
Ngoku, isisombululo esiphazamisayo sivuthiwe—inkqubo edibeneyo 'yokulungisa i-matrix ye-welding + ukuqinisa ukuchaneka kwe-laser cladding'. Oku akusiyo nje ukulungiswa, kodwa lutyalo-mali olucwangcisiweyo ekusebenzeni kwe-mold, kwaye iteknoloji ye-laser cladding yintloko yokuphinda kabini ixabiso le-molds.
I. Umxube weGolide: Uluhlu oluGqibeleleyo loLungiso oluQinisekileyo lwaMandla kunye nokuguquguquka
Inyathelo 1: Ukuwelda iSiseko – Ukuqinisa uBume beSimo seMold
Kwiziphene ezinkulu, imifantu okanye ilahleko ezinobukhulu kwisikhunta, kuqala sisebenzisa inkqubo yokuwelda esebenza kakhulu ukuzalisa nokwakha kwakhona. Eli nyathelo lifana "nokwakhiwa kwakhona kwamathambo", lijolise ekubuyiseleni isakhiwo sejometri enkulu kunye namandla apheleleyo esikhunta, kwaye libonelele ngesiseko esiqinileyo nesizinzileyo sonyango oluchanekileyo olulandelayo.
Inyathelo lesi-2: Ukugqitywa kwe-laser cladding – ukudala 'umphezulu we-super alloy' weemolds
Umzuzu apho ubuchwepheshe bethu obuphambili—ukugqunywa nge-laser—bufumana ukukhanya kwayo kuvela kwi-substrate eqinileyo edibeneyo. Le ayisiyonkqubo eqhelekileyo yokugqunywa; isebenzisa imisebe ye-laser enamandla aphezulu ukunyibilikisa ngoko nangoko iipowders zakho ezikhethekileyo ze-alloy (ezifana ne-cobalt-based, nickel-based, okanye i-metal-ceramic composites), ngaxeshanye zenza i-bond exineneyo ye-metallurgical kunye ne-substrate ye-mold.
Ubuhle bale nkqubo bubu:
Ulawulo oluchanekileyo: Umqadi welaser ufana "nemela yokukrola encinci", enokufikelela kumbala obhityileyo kakhulu we-0.1-2mm, ibuyisele ngokulula ukuchaneka kweprofayili yokuqala yokubumba, kwaye inciphise kakhulu okanye isuse inkqubo edinisayo yokusila ngokuchanekileyo kamva.
Ukutsiba kokusebenza: Umaleko wokugquma unika ubulukhuni bomphezulu obugqitha kakhulu obentsimbi yokubumba ngokwayo (ukuya kuthi ga kwi-HRC 60+), i-coefficient ephantsi kakhulu yokungqubana, kunye nokumelana okuhle kokuguguleka nokubola.
Umphezulu ogudileyo: ulwakhiwo lomaleko we-cladding luxinene kwaye lufana, olunokufumana ngokuthe ngqo ukugudiseka komphezulu ophezulu, kusombulula ngempumelelo iingxaki ze-pores kunye ne-pockmarks emva kokuwelda kwendabuko, kwaye luphucule ngokuthe ngqo umgangatho womphezulu weendawo ezifakwe isitampu.
II. Kutheni kufuneka ukhethe isisombululo sethu se-laser cladding? Ixabiso licacile
Ukudibanisa inkqubo yethu yokugquma nge-laser kwiinkqubo zakho zokwenza kunye nokuhlaziya isikhunta kuthetha ukuba uya kufumana izibonelelo zezi:
1. Uguquko kulawulo lwesikhunta ukusuka "kwizinto ezisetyenziswayo" ukuya "kwiimpahla"
Isikhunta asiseyona nto isetyenziswayo ekufuneka itshintshwe rhoqo. Ngokusebenzisa i-laser cladding reinforcement, ubomi benkonzo yomphezulu ophambili wokusebenza bunokwandiswa ngokuphindwe kabini ukuya kahlanu, nto leyo esasaza ngokungathanga ngqo iindleko zokuthenga isikhunta kumjikelo wobomi bonke, kwaye ifezekisa ukonga okukhulu kweendleko zexesha elide.
2. Ubunye bokuchaneka okugqithisileyo kunye nokusebenza kakuhle okugqithisileyo
"Ukuseta kube kanye, ukugqitywa ngamanyathelo amabini." Ukusebenza okudibeneyo kokuwelda kunye nokugquma kususa iimpazamo zokubeka izinto ezibangelwa kukuqhaqha nokuhlanganisa ngokuphindaphindiweyo. Itekhnoloji yokwenza imilo esondeleyo ye-laser cladding ikukhulula ekugayweni ngesandla okudinisayo kunye nokulinganisa okuphindaphindiweyo, inciphisa imijikelo yokulungisa ukuya kuthi ga kwi-70% kwaye ivumela iimolds ukuba zibuyele kwimigca yemveliso ngokukhawuleza.
3. "Lungisa endala, hayi entsha" —— Ukusebenza okugqitha uyilo lokuqala
Ungenza ngokwezifiso izinto ezifanelekileyo zokugquma ii-mold phantsi kweemeko ezithile zemveliso (ezifana neepleyiti zentsimbi ezinamandla aphezulu okanye ii-aluminium alloys). Oku kuthetha ukuba ii-mold ezilungisiweyo ziya kugqwesa ezintsha kwiimilinganiselo ezibalulekileyo zokusebenza, zivumele ukuba zikwazi ukujongana neemeko zokusebenza ezinzima ngelixa zibonelela ngokusebenza kakuhle kwemveliso kunye nomgangatho wemveliso.
4. Sebenzisa izinto ezikhoyo
Iinkuni eziphelelwe lixesha nezikwindawo yokusebenzela, "ezingenancasa ukuba zityiwe kodwa zixabiseke kakhulu ukuba zingalahlwa", "ziyimigodi yegolide" elindele ukumbiwa. Ubuchwepheshe bethu bunokuzenza "zizalwe ngokutsha" kwaye zibe "nomzimba onamandla", nto leyo ekhulisa ixabiso lezinto zakho ezikhoyo.
III. Bambisanani ngezandla ukuze nidale ikamva lokuhlaziya iimbumba ngobuchule
Siyaqonda ukuba yonke iseti yesikhunta inxulumene kakhulu nesigqi somgca wakho wemveliso. Asiboneleli nje kuphela ngezixhobo kunye nezixhobo ze-laser cladding eziphambili, kodwa sisisombululo esipheleleyo sokwandisa ubomi besikhunta kunye nokuphucula ukusebenza, kubandakanya uphuhliso lwenkqubo, uqeqesho lobuchwephesha, kunye nenkonzo eqhubekayo emva kokuthengisa.
Thatha inyathelo ngoku, masenze kunye:
Guqula iindleko eziphezulu zokutshintsha isikhunta zibe lutyalo-mali olusebenzayo.
Guqula iingozi ezingaqikelelweyo zexesha lokungasebenzi zibe zizicwangciso zemveliso ezizinzileyo nezilawulekayo.
Phucula iimold eziqhelekileyo zibe zizixhobo eziphambili ukuqinisekisa umgangatho wemveliso kunye nokukhuphisana kwimarike.
Masibambane ngezandla, ngokukhanya kwelaser, ukuze sigqume isikhunta sakho "ngobutsha" obungapheliyo, size sihambe siye kwikamva lokuvelisa izinto ngobuchule!
