Izesekeli zephrofayili ye-Aluminium - ubuchwepheshe be-weihua (i-aluminium extrusion nomkhiqizi), ngaphezulu kweminyaka eyi-10 ye-CNC aluminium extrusion processing, i-aluminium alloy yezimboni ukukhiqizwa kwe-aluminium extrusion processing processing, yonke inqubo yesevisi ukukuvumela ukuthi wonge isikhathi nomzamo ~ uxhumane nathi ngokushesha okukhulu
Kuyini ukubekezelelana ngokunemba kwe-aluminium extrusion?
1. Precision aluminium extrusion ukubekezelelana:
Ubuncane bodonga obukhulu bephrofayili bungu-0.4mm kuphela, futhi imfuneko yokubekezelelana ingu-± 0.04mm. Le ndlela yokuqhafaza ivame ukubizwa ngokuthi yi-precision aluminium extrusion.
Ukubekezelelana kwamaphrofayili amancane we-aluminium ngokunemba kungaphezu kwesigamu salokho kwebanga elikhethekile le-JIS, futhi ukubekezelelana kwamaphrofayli ngokunemba okujwayelekile kuphakathi kuka- ± 0.04 ~ ± 0.07mm.
Ubuncane bodonga obukhulu be-A1050, A1100, A3003, A6061, A6063 (low and medium energy alloy) amaphrofayli amancane anemba ngokukhipha yi-0.5mm, indawo encane yokuqhekeka ingama-20mm2. Ubuncane bodonga obukhulu be-A5083, A2024, A7075 (medium and high energy aluminium alloy) amaphrofayli amancane anemba ngokukhipha yi-0.9mm, indawo encane yokuqhekeka ingu-110mm2.
2. Izidingo zobuchwepheshe ngokunemba kwe-aluminium extrusion
Ngokuvamile, i-aluminium alloy hot extrusion deformation degree inkulu, ukushisa kwe-extrusion nezinguquko zejubane, imishini ye-extrusion eya kokungathathi hlangothi, ukufa kwe-deformation, njll., Kulula ukuthinta ukunemba kosayizi wephrofayili, futhi izici zabo zethonya lokuhlangana kunzima ukuzinqoba .
3, ukucacisa aluminium extrusion isikhunta izidingo
Isikhunta yisici esiqonde kakhulu esithinta ukunemba kobukhulu bemikhiqizo ekhishiwe.ukuqinisekisa ukuthi usayizi wesigaba somkhiqizo okhishiwe uhlala ungashintshi noma ushintsha kancane ekukhiqizeni, ukuqina, ukumelana nokushisa nokuqina kokugqokwa kwesikhunta kufanele kuhlangabezane nezidingo ezithile.
Okokuqala ukuqinisekisa ukuthi isikhunta ngaphansi kokushisa okuphezulu nokucindezela okukhulu akulula ukusonteka, kunokumelana nokushisa okuphezulu, okunamandla kakhulu kwe-extrusion eqondile, izidingo ekushiseni okusebenzayo (500 ℃), amandla wesikhunta wokukhiqiza amandla awekho ngaphansi kuka-1200 n / kwaba. Owesibili udinga ukumelana nokugqoka okuphezulu, okuncike kakhulu ebulukhuni nasebunzimeni bezingqimba ze-nitriding zidinga ubulukhuni besendlalelo se-nitrided ngaphezulu kwe-1150 hv, ukujula kwe-nitriding phakathi kuka-0.25 mm kuye ku-0.45 mm, kanye nezinguquko zosayizi wesikhunta we-nitride kufanele ube ngaphakathi kuka-0.02 mm.
Ngoba isigaba sinephrofayili eqinile kanye nephrofayili engenalutho yodonga lokumiswa, kepha futhi cabanga nge-deformation enwebeka yesikhunta, ukuze wenze isikhunta ukuqinisekisa ukuqina okuthile, ungacabanga ngokwanda okufanelekile kobukhulu besikhunta noma ngesimo esifanayo sephedi ekhethekile.
Ukulawula ushintsho losayizi wokuvula iphrofayili, inkatho yokuphambukisa ingenziwa kusikhunta ukulawula ukuhamba kwensimbi.
