Kev faib tawm ntawm cov txheej txheem ntawm cov tooj liab bar ntau lawm thiab kev piav qhia ntawm cov thev naus laus zis tseem ceeb, suav nrog cov txheej txheem txuas ntxiv txuas ntxiv thiab cov txheej txheem pom zoo txaus los tsim cov khoom siv tooj liab ultra-thin rau cov tsheb npav ducts
Lus Cim: Hluav taws xob tooj liab bar yog cov khoom siv tooj liab siab tam sim no. Nws yog siv rau hauv cov khoom siv hluav taws xob siab thiab tsis tshua muaj hluav taws xob, hloov kev sib cuag, cov khoom siv hluav taws xob faib hluav taws xob, cov tsheb thauj mus los thiab lwm yam khoom siv hluav taws xob. Nws kuj yog siv dav hauv hlau smelting, electrochemical plating, tshuaj caustic soda thiab lwm yam ultra-high tam sim no smelting. Los yog cov khoom siv electrolysis; tus ntoo khaub lig-sectional duab yog ib lub duab plaub hla-section nrog 4 rounded fab thiab cov kev cai; nws muaj mechanical zog thiab hluav taws xob conductivity zog. 1. Copper bar Hluav taws xob tooj liab bar yog cov khoom siv tooj liab siab tam sim no. Nws yog siv rau hauv cov khoom siv hluav taws xob siab thiab tsis tshua muaj hluav taws xob, hloov kev sib cuag, cov khoom siv faib khoom, cov tsheb thauj mus los thiab lwm yam khoom siv hluav taws xob. Nws kuj yog siv dav hauv hlau smelting, electrochemical plating, tshuaj caustic soda thiab lwm yam loj heev tam sim no smelting los yog electrolysis khoom; tus ntoo khaub lig-section zoo yog ib lub duab plaub hla-section nrog 4 rounded fab thiab cov kev cai; nws muaj mechanical zog thiab hluav taws xob conductivity zog. 2. Copper busbar ntau lawm txheej txheem Cov txheej txheem tooj liab busbar yog feem ntau muab faib ua ob qho tib si dov thiab extrusion txheej txheem. Cov txheej txheem khiav yog ntev, cov txheej txheem yog complex, lub zog noj yog siab, thiab cov khoom siv yog tsawg. A. Loj ingot kub-dov coil billet - high-precision txias dov txoj kev: Loj ingot kub dov kauj billet muaj mature technology. Kub dov tuaj yeem hloov pauv cov qauv casting, tab sis cov txheej txheem ntws tau ntev thiab cov cuab yeej siv tau loj. B. Kab rov tav nruam nruam casting coil billet - high-precision txias dov txoj kev: Kab rov tav los yog upward nruam nruam casting coil billet, cov txheej txheem luv luv, cov cuab yeej siv qis qis, seem casting qauv tom qab txias dov, yuav tsum tau deg milling, uas ua rau tus nqi qis. Nruam extrusion txheej txheem: Tus tshiab nruam extrusion txheej txheem thev naus laus zis tuaj yeem ua ke qhov zoo ntawm ob txheej txheem saum toj no. Cov khoom lag luam muaj cov qauv zoo (piv rau cov qauv kub dov), cov txheej txheem luv luv, cov txiaj ntsig siab, tsis muaj peev txheej hauv cov khoom siv thiab cov nroj tsuag, thiab txo cov kev lag luam nkag. pib. 3. Qhov zoo ntawm cov txheej txheem nruam extrusion: ► Siv nruam casting thiab dov hlau pas nrig ua raw khoom, nws yog ib qho yooj yim rau muab, tsis muaj extrusion siab residue, cov khoom siv tus nqi siab, feem ntau mus txog 95%, thiab cov uniformity ntawm structural zog yog zoo. ► Nruam extrusion siv cov cua sov tsim los ntawm kev sib txhuam kom sov tsis muaj cua sov, yog li txuag lub zog. ► Cov txheej txheem tsawg dua, kev ua haujlwm siab ntau lawm thiab cov khoom lag luam siab. ► tuaj yeem paub cov khoom lag luam txuas ntxiv yam tsis muaj lub sijhawm. ► Cov khoom siv ntev ntev tuaj yeem tsim tau. Kev ua cov txheej txheem ib txwm ua feem ntau tsis pub tshaj 30-50m, thaum qhov ntev ntawm cov txheej txheem txuas ntxiv tuaj yeem feem ntau yog li ntawm ntau txhiab meters mus rau kaum tawm txhiab meters. Lawv raug xa hauv daim ntawv yob thiab yooj yim rau kev thauj mus los. 4. Hom kev siv ntawm kev nruam extrusion: ► Tube tube manufacturing ► CATV coaxial cable sab nrauv thiab kev sib txuas lus teeb liab cable sheath manufacturing ► Aluminium-clad steel hlau raug ► High-speed railway tooj liab alloy hu xov tooj raug ► tooj liab ca hlau thiab tooj liab bar manufacturing ► Cov kab txuas ntxiv txuas ntxiv txuas ntxiv ntawm cov hlau tsis muaj pa oxygen: Qhov dav txuas txuas ntxiv yog txwv, feem ntau vim tias qhov dav siab tshaj plaws yog 300mm. Cov teeb meem tseem ceeb: yuav ua li cas sau cov kab noj hniav thiab yuav ua li cas kom ntseeg tau qhov sib xws ntawm kev khiav ceev thaum lub sij hawm strip extrusion txheej txheem. 5. Kev daws: ► Pib tshawb fawb los ntawm cov yam ntxwv ntawm billet preheating kub, teeb tsa cov pwm tsis zoo thiab tsim nyog xaiv lub zog extruder ► Cavity tsim ► Pwm cov khoom thiab cov khoom siv tom qab txias thiab extrusion: ► Cov khoom tom qab txuas ntxiv extrusion Cov qauv yog recrystallized qauv. , tsis muaj plastically tsim streamlined qauv; ► Cov qauv zoo ib yam thiab zoo, qhov saum npoo yog du thiab tiaj tus yam tsis muaj oxidation, tsis tas yuav tsum tau kho deg, thiab tom qab dov ua tiav tuaj yeem ua ncaj qha; ► Lub hardness ntawm liab tooj liab tom qab extrusion yog hais txog HV60-70, Nws yog nyob rau hauv ib tug mos mos lub xeev thiab yog haum rau tom qab dov ua nrog loj deformation. 6. Txhawm rau tsim cov khoom siv tooj liab ultra-nyias rau busbar ducts, cov txheej txheem pom zoo yog: nce → extrusion → dov → annealing → kos duab. Lub dov tus nqi ntawm lub billet yog txwv, thiab lub thickness ntawm cov dov ib nrab ntawm cov khoom yog feem ntau ntau dua 2 hli, uas yuav txaus siab los ntawm kev siv ib tug ob-yob zeb. , kom tsis txhob nkim functionality. Nruam extrusion manufacturing ntawm hollow cross-section conductive tuav (profiles): Hollow cross-section tooj liab tuav (profiles) yog dav siv nyob rau hauv electronics, hluav taws xob fais fab thiab lwm yam teb. Kev tsim khoom ntawm ntau lub hollow heterogeneous cross-section bar yog qhov nyuaj thiab kim, thiab kev ua lag luam tsis yooj yim pom. Ib txwm hollow billet perforation extrusion txoj kev: tsuas tuaj yeem tsim cov duab yooj yim thiab qhov loj me (dhau 50mm hauv txoj kab uas hla); Nws yog ib qho nyuaj rau tsim cov profiles nrog nyias phab ntsa, qhov me me, thiab ntev ntev. Kev lig kev cai - ncab txoj kev: feem ntau tsim heterosexual kav nrog niaj hnub phab ntsa thickness. Nws yog ib qho nyuaj rau ua tiav heterogeneous kav nrog cov phab ntsa tsis sib xws thiab tsis yog kev lag luam. Thoob ntiaj teb kev tsim tshuab: dav kab nruam extrusion - ncaj kab extrusion, khoov ua ntej thiab tom qab ntawd ncaj, thiab hollow kab nruam extrusion.
