Raws li txoj kev no, aluminium thiab aluminium alloy ua tau muab faib ua dov, extrusion, kos duab, forging, spinning, sib sau ua thiab sib sib zog nqus ua.
A. Rolling
Rolling yog txheej txheem yas deformation nyob rau hauv uas lub ingot yog rub mus rau hauv lub rotating rollers los ntawm kev sib txhuam, thiab tus ntoo khaub lig seem yog txo, cov duab yog hloov, lub thickness yog thinned, thiab qhov ntev yog nce nrog kev pab los ntawm lub siab exerted. rollers. Nyob ntawm qhov kev taw qhia ntawm kev sib hloov ntawm yob, dov tuaj yeem muab faib ua longitudinal dov, hla dov thiab hla dov. Thaum lub sij hawm longitudinal dov, txoj kev sib hloov ntawm kev ua hauj lwm yob yog qhov sib txawv, thiab cov axis longitudinal ntawm cov dov thiab cov axis ntawm cov yob yog perpendicular rau ib leeg. Nws yog txoj kev siv ntau tshaj plaws hauv cov yob yob yob ntawm aluminium alloy daim hlau, strips, thiab foils; Thaum lub sij hawm hla dov, kev sib hloov ntawm kev ua hauj lwm yob yog qhov kev sib hloov kev taw qhia yog tib yam, lub longitudinal axis ntawm daim dov thiab yob axis yog sib npaug rau ib leeg, uas tsis tshua muaj siv nyob rau hauv dov ntawm aluminium alloy daim hlau thiab strips; Thaum lub sij hawm hla dov, lub yob ua hauj lwm tig nyob rau hauv tib txoj kev, thiab lub longitudinal axis ntawm lub dov daim yog ua raws li cov yob axis. txoj kab nqes. Double-roller lossis multi-roller cross-rolling feem ntau yog siv rau hauv kev tsim cov yeeb nkab aluminium alloy thiab qee yam khoom tshwj xeeb. Raws li cov txheej txheem sib txawv, aluminium alloy dov tuaj yeem muab faib ua ob-txheej txheej dov, ntau lub tshuab dov thiab cov txheej txheem tshwj xeeb (xws li planetary dov, V-shaped dov, thiab lwm yam) dov: raws li cov yob sib txawv, aluminium alloy Rolling tuaj yeem muab faib ua lub tiaj tiaj dov thiab zawj yob dov. Raws li cov khoom sib txawv, aluminium alloy dov tuaj yeem muab faib ua phaj, sawb, ntawv ci dov, bar, tiaj tus bar thiab tshwj xeeb zoo li profile dov, yeeb nkab thiab hollow profile dov, thiab lwm yam.
B. nyem
Extrusion yog ib txoj hauv kev ntawm kev thauj khoom mus rau hauv lub thawv extrusion, siv lub siab rau cov hlau los ntawm extrusion ncej, thiab extruding nws los ntawm lub qhov tuag ntawm ib tug muab cov duab thiab loj, ua rau cov yas deformation kom tau cov khoom extrusion xav tau. txoj kev ua. Cov kev taw qhia ntawm cov hlau ntws sib txawv thaum lub sij hawm extrusion. Extrusion tuaj yeem muab faib ua rau pem hauv ntej extrusion, thim rov qab extrusion thiab ua ke extrusion. Thaum lub sij hawm rau pem hauv ntej extrusion, lub zog kev taw qhia ntawm lub extrusion ncej yog raws li nyob rau hauv lub ndlwg ntawm cov extruded hlau, thaum lub sij hawm rov qab extrusion, lub zog kev taw qhia ntawm lub extrusion ncej yog opposite rau lub ntws kev taw qhia ntawm lub extruded hlau. Raws li cov cua kub ntawm lub ingot, extrusion yuav muab faib ua kub extrusion thiab txias extrusion. Nyob rau hauv kub extrusion, lub ingot yog rhuab mus rau saum lub recrystallization kub rau extrusion, thaum nyob rau hauv txias extrusion, lub ingot yog extruded nyob rau hauv chav tsev kub.
C. rub
Kev kos duab yog lub tshuab ncab (los yog lub tshuab kos duab) uas siv cov clamps los rub tawm cov txhuas thiab txhuas alloy blanks (xaim blanks lossis raj blanks) los ntawm pwm ntawm cov duab thiab qhov loj me, ua rau lawv cov yas deform kom tau raws li qhov xav tau. Cov txheej txheem ua cov raj, pas nrig, cov duab thiab cov xov hlau. Raws li ntau yam thiab cov duab ntawm cov khoom tsim, ncab tuaj yeem muab faib ua hlau ncab, yeeb nkab stretching, bar stretching thiab profile stretching. Cov yeeb nkab kos duab tuaj yeem muab faib ua cov duab kos, core head drawing thiab floating core head drawing. Cov ntsiab lus tseem ceeb ntawm cov txheej txheem ncab yog lub tshuab ncab, lub stretching tuag thiab stretching reel. Raws li lub stretching pwm txuam, stretching yuav muab faib ua ib hom stretching thiab multi-hom stretching.
D.Forging
Forging yog ib txoj kev ua haujlwm uas lub forging rauj lossis xovxwm (mechanical lossis hydraulic) siv lub siab rau txhuas thiab aluminium alloy ingots los yog forging blanks los ntawm lub taub hau rauj los yog indenter ua rau cov yas deformation ntawm cov hlau. Muaj ob txoj hauv kev ntawm aluminium alloy forging: dawb forging thiab tuag forging. Dawb forging yog tso lub workpiece ntawm tiaj tus anvils (los yog anvils) forging; tuag forging yog muab lub workpiece nyob rau hauv ib tug pwm ntawm ib tug muab qhov loj me thiab cov duab, thiab ces siv siab rau lub workpiece forging deformation kom tau qhov yuav tsum tau tuag forging. . Txoj kev kho forging yog ib feem tseem ceeb ntawm cov txheej txheem aluminium alloy tuag forging. Txij li thaum aluminium alloy yog mos, viscous heev thiab tsis muaj fluidity ntawm qhov kub thiab txias, nws yog ib qho yooj yim rau lo rau pwm thiab tsim ntau yam defects (folding, burrs, tawg, thiab lwm yam). Ua ntej yuav mus rau cov txheej txheem tom ntej, nws yuav tsum tau polished, kho, thiab tshem tawm qhov tsis xws luag. Huv si, txwv tsis pub cov teeb meem yuav nthuav dav ntxiv hauv cov txheej txheem tom ntej thiab tseem ua rau forgings yuav tsum tau muab pov tseg.
Cov cuab yeej siv los kho muaj xws li pneumatic grinders, pneumatic milling cutters, hluav taws xob milling cutters thiab shovels tiaj tus. Ua ntej kho qhov kev puas tsuaj, ua ntej xyuas qhov chaw puas los ntawm corrosion. Qhov chaw kho yuav tsum muaj kev hloov pauv, thiab nws qhov dav yuav tsum yog 5 mus rau 10 npaug ntawm qhov tob.
