Zeziphi iindlela eziqhelekileyo ezisetyenziselwa ukucima izixhobo zokucima rhoqo

Iindlela zokucima eziqhele ukusetyenziswa kwizixhobo zokucima isantya esiphezulu zezi:

1. Ukucima okukodwa okuphakathi

Inzuzo yokucima i-single-medium kukuba kulula ukuyisebenzisa, kodwa ifanelekile kuphela kwi-workpieces encinci kunye ne-shaped-shaped-shaped workpieces, kwaye ijwayele ukuguqulwa okukhulu kunye nokuqhekeka kwezinto zokusebenza ezinobungakanani obukhulu.

2. Ukucima okuphakathi kabini

Ukucinywa kabini okuphakathi kukutshisa i-workpiece ukuze i-austenitize kwaye emva koko intywiliselwe kwindawo enobuchule obunamandla bokupholisa. Xa uguqulo lwesakhiwo se-martensite luza kwenzeka, lugqithiselwa ngokukhawuleza kwindawo enesakhono sokupholisa esibuthathaka ukuqhubeka nokupholisa. Ngokubanzi, amanzi asetyenziswa njengendawo yokucima ukupholisa ngokukhawuleza, kwaye i-oyile isetyenziswa njengendlela yokucima ukupholisa kancinci. Ngamanye amaxesha ukucima amanzi kunye nokupholisa umoya kunokusetyenziswa. Ukucima okuphakathi kabini kunokuthintela ngcono ukuguqulwa kwezinto zokusebenza kunye nokuqhekeka. Izixhobo zokusebenza ezinkulu ze-carbon steel zifanelekile ukucima ngale ndlela.

3, ukucinywa kwamanqanaba

Le ndlela yokucima inciphisa kakhulu umthamo wokucima ngenxa yobushushu obufanayo ngaphakathi nangaphandle kwendawo yokusebenza kwaye igqibezela inguqu ye-martensitic phantsi kweemeko zokupholisa ngokukhawuleza, ngaloo ndlela inciphisa ngokufanelekileyo okanye ithintele ukuguqulwa kunye nokuqhekeka kwe-workpiece, kwaye yoyise kwakhona ubunzima bokulawula amanzi. kunye neoli ekucinyweni okubini-okuphakathi. Iintsilelo. Nangona kunjalo, ngenxa yobushushu obuphezulu bendawo yokupholisa kule ndlela yokucima, izinga lokupholisa kwindawo yokusebenza kwindawo yokuhlambela yealkali okanye kwibhafu yetyuwa liyacotha, ngoko ke ixesha lokulinda lilinganiselwe, kwaye kunzima ukuba iindawo ezikwicandelo elikhulu ukufikelela kwinqanaba elibalulekileyo lokucima. umsebenzi omncinci.

4. Ukucima isothermal

I-Austempering inokunciphisa kakhulu i-deformation kunye nokuqhekeka kwee-workpieces, kwaye ifanelekile ukusetyenzwa okuntsokothileyo, ukuchaneka okuphezulu kunye neendawo ezibalulekileyo zoomatshini, ezifana nokubumba, izixhobo kunye nezixhobo. Njengokucima okuhleliweyo, ukucinywa kwe-isothermal kunokufakwa kuphela kwizinto ezincinci zokusebenza. Isixhobo esiphakathi kunye nesiphezulu sokucima isixhobo somatshini kufuneka senze isigqibo sokuba yeyiphi indlela yokucima oza kuyisebenzisa ngokwesixhobo sokusebenza ekufuneka usicime. Isixhobo esincinci sinokufezekiswa ngokucinywa kwemidiya enye.

Ukongeza kwiindlela zokucima ezi ngasentla kwinkqubo yokucima umatshini wokucima izixhobo eziphezulu, ezininzi iinkqubo ezintsha zokucima ziye zaphuhliswa ukuphucula amandla kunye nokuqina kwentsimbi kwiminyaka yamuva nje, njengokucima ubushushu obuphezulu, ukucima ukutshisa ngokukhawuleza kwe-cyclic, njl.
