Umgangatho:GB/T 699-1999

iimpawu
Ubukhulu bungaphezulu kancinane kunentsimbi ye-15, ayifane icime, akukho msindo ovuthayo owenziwe nge-deformation plasticity ephezulu jikelele yokugoba i-calender flanging kunye nokulungiswa kwehamile, okufana ne-arch arc welding kunye nokumelana nokuwelda ukusebenza kakuhle kwe-welding, i-welding xa ubukhulu buncinci, imbonakalo engqongqo okanye imilo yamalungu anzima athambekele ekuqhekekeni kwi-machining ye-machining yesimo esiqhelekileyo sokwenza okuqhelekileyo okuqhelekileyo okanye ukuveliswa kwamandla okuqhelekileyo okwenziwa yingqele. ubunzima obuphezulu
Intsimbi yeyomgangatho ophezulu we-carbon carbon steel, i-cold extrusion carburized hardening steel, intsimbi inamandla aphantsi, iqinile, iplastiki kunye ne-weldability, amandla okuqina angama-355-500mpa, isantya sobude be-24%
I-normalizing inokukhuthaza i-spheroidization yentsimbi, icokise i-block proeutectoid ferrite enkulu, kwaye iphucule ukusebenza kokusika kwezithuba ezingaphantsi kwe-160HBS.
Indlela yetekhnoloji yeintsimbiiinxalenye ezifayo zezi: i-casting forging die blank machine annealing machine rough machining cold extrusion molding recrystallization annealing machineing fine machining carburizing quenching the tempering grinding assembly

olunye ulwazi

Inkcazo yonyango lobushushu: i-normalizing, i-910 ℃, ukupholisa umoya.

Ubume beMetallographic: ferrite + pearlite.
Unyango lobushushuyentsimbi 20 kunye nokucima ubulukhuni bentsimbi no. 20:
Ukunyangwa kobushushu bentsimbi ye-20: Ngentsimbi ye-20, kunokwenzeka ukuba ufezekise ubulukhuni obuqhelekileyo bokucima i-30-35HRC.Ngenxa yokuba ubushushu bokufudumala buphezulu, i-deformation yokucima inkulu.Jonga:
1. Emva komatshini obunzima, i-workpiece iyacinywa ngokupheleleyo ngonyango lokushisa (i-920 ℃ quenched brine), kwaye emva koko icutshungulwe.Ngenxa yeemfuno zobunzima be-30-35HRC, zonke iinkqubo kufuneka zikwazi ukucutshungulwa, akukho nto ngaphezu kwelungileyo ngaphakathi nangaphandle kwesangqa semoto, ukulungisa indlela engundoqo.
2. Umatshini orhabaxa ofanayo, ukucinywa komngxuma ongaphakathi okanye isitshixo sokucinywa kwetafile kuphela (kuxhomekeke kubungakanani besixhobo sokusebenza), kwaye ekugqibeleni kugqitywe.
3. Ukungcwatywa kunye nokucima, ukugaya umngxuma ongaphakathi kunye nesitshixo.
Inkqubo yokuhamba yeyesibini, yesithathu kunye neyona nto ininzi.
● Imeko yonikezelo: ukuhanjiswa kwimeko yokungabikho konyango lobushushu okanye unyango lobushushu (i-annealing, normalizing okanye iqondo lobushushu eliphezulu). Ukuhanjiswa kwimeko yonyango lobushushu kuya kuboniswa kwikhontrakthi. Ukuba ayiboniswanga, ukuhanjiswa kuya kwenziwa ngaphandleunyango lobushushu.
