Izixhobo zeprofayili yeAluminiyam - itekhnoloji ye-weihua (umenzi we-aluminium extrusion), ngaphezulu kweminyaka eli-10 ye-CNC yokuqhekeza i-aluminium extrusion, i-aluminium ingxubevange yemveliso ye-aluminium extrusion eqhubayo, yonke inkqubo yenkonzo ukukuvumela ukuba ugcine ixesha kunye nomzamo ~ thetha nathi ngokukhawuleza
Yintoni ukuchaneka kokunyamezelana kwealuminium extrusion?
1.Ukunyamezelana ngokuchanekileyo kwealuminium extrusion:
Ubuncinci bobukhulu bodonga kwiprofayili yi-0.4mm kuphela, kwaye imfuneko yokunyamezelana yi-± 0.04mm. Obu buchule be-extrusion buhlala bubizwa ngokuba yi-aluminium extrusion echanekileyo.
Ukunyamezelana kweeprofayili ezincinci ze-aluminium ezichanekileyo kungaphezulu kwesiqingatha kuloo mabakala akumgangatho okhethekileyo we-JIS, kunye nokunyamezelana kweeprofayili zealuminium ezichanekileyo kuphakathi kwe- ± 0.04 ~ ± 0.07mm.
Ubuncinci bobukhulu bodonga lwe-A1050, A1100, A3003, A6061, A6063 (amandla aphantsi naphakathi alloy amandla) iiprofayili ezincinci ezichanekileyo ezikhutshiweyo yi-0.5mm, indawo encinci yokuqhekeka yi-20mm2. Ubuncinci bobukhulu bodonga lwe-A5083, A2024, A7075 (amandla aphakathi kunye namandla aphezulu ialuminium alloy) iiprofayili ezincinci ezichanekileyo ezikhutshiweyo zi-0.9mm, eyona ndawo iqhekekileyo yi-110mm2.
2. Iimfuno zobugcisa ngokuchaneka kwe-aluminium extrusion
Ngokubanzi, ialuminium ingxubevange eshushu isidanga sokususwa sikhulu, ubushushu be-extrusion kunye notshintsho kwisantya, izixhobo ze-extrusion ukuya kokungathathi hlangothi, ukusweleka kokufa, njl., Kulula ukuchaphazela ubungakanani beprofayili, kunye nefuthe labo bobabini kunzima ukoyisa .
I-3, ukuchaneka kweemfuno ze-aluminium extrusion
Ukubumba yeyona nto ithe ngqo echaphazela ubungakanani beemveliso ezigqityiweyo.ukuqinisekisa ukuba ubungakanani becandelo lemveliso ekhutshiweyo buhlala bungaguqukanga okanye butshintsha kancinci kwimveliso, ukuqina, ukumelana nobushushu kunye nokuthintela ukungunda kufuneka kuhlangane neemfuno ezithile.
Okokuqala ukuqinisekisa ukungunda phantsi kobushushu obuphezulu kunye noxinzelelo oluphezulu akukho lula ukuba deformation, inokumelana nobushushu obuphezulu, ingqongqo ngakumbi kwi-extrusion echanekileyo, iimfuno kubushushu obusebenzayo (500 ℃), amandla okubumba amandla okuvelisa akakho ngaphantsi kwe-1200 n / wayenjalo. Okwesibini kufuna ukumelana nokunxiba okuphezulu, okuxhomekeke ikakhulu kubulukhuni kunye nobunzima be-nitriding layer jikelele yeemfuno zobulukhuni be-nitrided layer ngaphezulu kwe-1150 hv, ubunzulu be-nitriding phakathi kwe-0.25 mm ukuya kwi-0.45 mm, kunye notshintsho lobungakanani besikhunta senitride kufuneka ube ngaphakathi kwe-0.02 mm.
Kuba icandelo ineprofayili eqinileyo kunye iprofayili kumngxuma udonga ukunqunyanyiswa, kodwa kwakhona siqwalasele deformation elastic sokubumbela, ukuze wenze ukungunda ukuqinisekisa ukuqina ethile, ungaqwalasela ukwanda efanelekileyo Ebubanzini ukungunda okanye imilo efanayo iphedi ekhethekileyo.
Ukulawula utshintsho kubungakanani bokuvula iprofayili, indawo yokuphambukisa inokwenziwa ekubunjweni ukulawula ukuhamba kwesinyithi.
