Itekhnoloji yokuvelisa
Inkqubo yemveliso ye bar mandrel iqulathe amanyathelo eziliqela ezintsonkothileyo nachanekileyo.Eyokuqala yizinto ezincibilikayo, eziqinisekisa ukufana kunye nokucoceka kwe-core bar.Emva koko i-forging, ngokusebenzisa inkqubo yokubumba, ingqolowa yezinto eziphathekayo ihlanjululwa, ngaloo ndlela iphucula iimpawu zayo zomatshini kunye nobomi benkonzo.I-mandrel eyakhiweyo ifuna unyango lobushushu, inkqubo esusa uxinzelelo lwangaphakathi kwaye yandisa ubulukhuni kunye nokumelana nokunxiba kwe-mandrel.Emva koko, machining, kuquka ukujika, lokusila kunye neminye imisebenzi, yenza mandrel ukuhlangabezana neemfuno ukuchaneka uyilo.Inyathelo lokugqibela unyango umphezulu, ezifana quenching, tempering, njalo njalo, ukwandisa ukumelana umhlwa kunye nobulukhuni umphezulu mandrel.
Ubungakanani besicelo kunye neenkcukacha
Ibha ye-Mandrel isetyenziswa ngokubanzi kwiindidi ezahlukeneyo zokusila, njengeMPM (i-multi-pass rolling mill), i-PQF (i-high precision rolling mill) kunye ne-FQM (i-fast rolling mill).Uluhlu lwayo lweenkcukacha, ukusuka kwi-Φ80 mm ukuya kwi-500 mm ububanzi, ubude ukusuka kwi-2500 mm ukuya kwi-17,500 mm, inokuhlangabezana neemfuno ezahlukeneyo zokuvelisa.
Ukukhetha izinto eziphathekayo
Izinto zebar mandrel ngokuqhelekileyo AISI H13 okanye umgangatho wesizwe 4Cr5MoSiV1 kunye 36CrNiMoV6.Ezi zixhobo zineempawu eziphezulu zokushisa okuphezulu kunye namandla omatshini ukugcina uzinzo kwiqondo lokushisa eliphezulu kunye neendawo zoxinzelelo oluphezulu.Inclusions non-metallic kwizinto mandrel kufuneka ukuba akukho ngaphezu 1.0 grade A, B, C no D, kunye nobungakanani eziziinkozo kufuneka ukufikelela 8 ibakala okanye ngaphezulu.Ezi mfuneko zezinto ezingqongqo ziqinisekisa umgangatho ophezulu kunye nokuthembeka kwebar ye-mandrel.
Ipropathi yoomatshini
Iipropathi ezicetyiswayo zomatshini webha ye-mandrel yezinto ze-H13 zimi ngolu hlobo lulandelayo: Kwi-mandrel enobubanzi ≤200 mm, amandla e-tensile yi-1127-1274 mpa, amandla esivuno ngu-≥931MPa, ukunyuswa ngu-≥8%, icandelo liyancipha. ngu ≥25%, umsebenzi wempembelelo ngu ≥20J, kwaye ubunzima yi-HB350-390;Kwi-mandrel enobubanzi be-200 mm, amandla ayo okuqina yi-1078-1274 mpa, amandla emveliso yi-≥882MPa, i-elongation yi-≥8%, i-shrinkage yecandelo yi-≥25%, umsebenzi wempembelelo ngu-≥20J, ukuqina ngu-HB330-375.
