Imibuzo Ebuzwa Rhoqo
Yintoni ebangela iiburrs ezigqithisileyo kwisitampu sombane kwitheminali?
Iibhura ezigqithisileyo zibangelwa ikakhulu kwi-punch edges egugileyo, ukukhutshwa okungachanekanga kwepunch-to-die, okanye imathiriyeli enzima kunokuba uyilo lwezixhobo luvumela. Xa imvume idlula i-10% yobukhulu bezinto eziphathekayo, i-edge echetyiweyo ivelisa indawo ejikelezayo kunye ne-burr enokugqithisa i-0.05 mm. Iishedyuli zothintelo lolondolozo kufuneka zibize i-punch regrinding rhoqo kwi-500,000 ukuya kwi-1,000,000 izibetho, kunye nobunzima bezinto ezingenayo kufuneka buqinisekiswe ngokuchasene nenkcazo yoyilo lokufa.
Ndikhetha njani phakathi kwe-phosphor bronze kunye neberyllium yobhedu kwiitheminali zokudibanisa?
Phosphor bronze (C51000, C52100) yinto engagqibekanga kuninzi lweziqhagamshelo zentengiso - inika i-conductivity enhle (13-15% IACS), ubomi obuhle kakhulu bokudinwa, kunye neendleko eziphakathi. I-Beryllium copper (i-C17200) yinkqubo yokukhetha i-premium xa ufuna i-conductivity ephezulu (i-22% IACS), ukuphumla okuphezulu koxinzelelo kumaqondo okushisa aphakamileyo, okanye ubomi bomjikelezo ophezulu kakhulu ngaphezu kwe-10,000 yokukhwelana. Ukurhweba kukuba i-BeCu ixabisa i-3-5 × ngaphezu kwe-bronze ye-phosphor kwaye idinga unyango lobushushu obudala emva kokuqulunqwa.
Yeyiphi iplating eyona ilungileyo kwiitheminali zombane zeemoto?
I-Mat plating (2.5–5.0 µm) ngaphezulu kwe-nickel underplate (1.0–2.0 µm) ngumgangatho weetheminali zeemoto. I-Tin inika ukuthengiswa okugqwesileyo, ukuchasana okwaneleyo koqhagamshelwano (10–15 mΩ), kunye nokukhuselwa kakuhle kwe-corrosion kwiindawo ezingaphantsi kwe-hood. Kwimingxuma edityanisiweyo etywiniweyo kwiinkqubo zokhuseleko ezibalulekileyo (i-airbag, i-ADAS), ezinye ii-OEMs zichaza igolide-ngaphezulu kwe-nickel ukuqinisekisa ukuthembeka koqhagamshelwano lwe-zero-falure kwiminyaka eyi-15 yobomi besithuthi.
Ichaneke kangakanani indlela yokucofa isitampu esinesantya esiphezulu kwiitheminali zombane?
Isitampu sangoku esiqhubekayo kumatshini wokushicilela wesantya esiphezulu siphumeza ±0.01 mm ukuchaneka kwendawo yeempawu ezifana nemingxuma kunye neencam zoqhagamshelo, ngexabiso le-Cpk le-1.33 okanye ngaphezulu. Ukunyamezela ubude besiphelo se-±0.03 mm kunye nee-engile zokugoba ngaphakathi kwe-±0.5 ° zifumaneka rhoqo kwi-600-1,200 SPM. Ukufezekisa oku kunyamezela kufuna i-carbide tooling, i-servo feeds kunye nokubhaliswa kwe-pilot-pin, i-in-die sensing, kunye neendawo zokushicilela ezilawulwa ngubushushu.
Ngowuphi owona nobangela uxhaphakileyo wokuxobuka kweplating kwiitheminali ezinesitampu?
Ukucwecwa kwe-Plating kaninzi kuphumela ekungalungiseni kakuhle komphezulu phambi kokufakwa kwe-electroplating. I-isitampu i-lubricant residu, iifilimu ze-oxide, kunye neengqungquthela ezixubileyo ezixubileyo zithintela ukunamathela ngokufanelekileyo komgangatho odibeneyo. Ukongeza i-nickel underplate (1.0–2.5 µm) phakathi kwesiseko sealloyi yobhedu kunye netoti yokugqibela okanye itopcoat yegolide iphucula ngokumangalisayo ukuncamathelisa kwaye isebenza njengesithintelo sokusasaza. Umgca wokucoca kufuneka ubandakanye ukucoca i-electro-clean, ukusebenza kwe-asidi, kunye ne-rinse cascade ngaphambi kokuba i-nickel ibethe.
Ukuqukumbela
Isitampu kwitheminali yombane yinkqubo echanekileyo apho ukutenxa kuncinci kudala iingxaki ezibalulekileyo zokuthembeka emazantsi omlambo.
