Ukwenza iziphene
Injongo yokubumba kukucinezela iziphene ze-porosity zangaphakathi ze-ingot yensimbi ukwenza isakhiwo sixinene kwaye sifumane umgca wokuhamba kakuhle wesinyithi. Inkqubo yokwenza kukwenza ukuba isondele ngokusemandleni kwimilo ye-workpiece. Iziphene eziveliswe ngexesha lokukhwabanisa zibandakanya ukuqhekeka, iziphene zangaphakathi zokubumba, izikali ze-oxide kunye nokugoba, imilinganiselo engafanelekanga, njl.
Izizathu eziphambili zokuqhekeka kukufudumala kwe-ingot yensimbi ngexesha lokufudumeza, ukushisa okuphantsi kakhulu, kunye nokunciphisa uxinzelelo olugqithisileyo. Xa ubushushu bokubumba buphantsi kakhulu, izinto ngokwazo zineplastiki ehluphekileyo, kunye nesixa sokunciphisa uxinzelelo ngexesha lokudala iintanda zeTensile, njl. Ukongeza, iintanda eziveliswe ngokubumba azicocwa lula ngexesha okanye azicocwanga ngokupheleleyo, ezinokulula. bangela ukuba iintanda zande ngakumbi. Iziphene zokubumba zangaphakathi zibangelwa ubukhulu becala ngenxa yokungonelanga koxinzelelo okanye umlinganiselo onganelanga woxinzelelo, uxinzelelo alukwazi ukuhanjiswa ngokupheleleyo kwi-core ye-ingot yensimbi, imingxuma yokunciphisa eyenziwe ngexesha le-ingot ayinyanzelwanga ngokupheleleyo, kwaye i-dendritic grains. ayaphulwanga ngokupheleleyo Ukucutheka kunye nezinye iziphene. Isizathu esona sizathu somlinganiselo kunye nokusonga kukuba isikali esiveliswayo ngexesha lokubunjwa asicocwanga ngexesha kwaye sicinezelwe kwi-forging ngexesha lokukhwabanisa, okanye kubangelwa inkqubo engafanelekanga. Ukongeza, ezi ziphene zinokuthi zenzeke xa umphezulu wendawo engenanto ungalunganga, okanye ukufudumeza kungalingani, okanye i-anvil kunye nomthamo wokunciphisa osetyenziswayo awufanelekanga, kodwa ngenxa yokuba isiphene esingaphezulu, sinokususwa. ngeendlela zoomatshini. Ukongezelela, ukuba ukufudumeza kunye nokukhwabanisa imisebenzi ayifanelekanga, kunokubangela ukuba i-axis ye-workpiece ikhutshwe okanye isetyenziswe kakubi. Oku kubizwa ngokuba yi-eccentricity kunye nokugoba kwi-forging operation, kodwa ezi ziphene ziziphene ezilungisekayo xa ukubunjwa kuqhubeka.

Uthintelo lweziphene ezibangwa kukubunjwa ikakhulu kubandakanya:

(1) Ukulawula ngokufanelekileyo iqondo lobushushu ukunqanda ukutshisa kakhulu kunye nobushushu obuphantsi;

(2) Ukuphucula inkqubo yokuqulunqa, amasebe amaninzi aya kutyikitya inkqubo yokuqulunqa kwaye aqinise inkqubo yokuvunywa kwenkqubo;

( 3) Ukuqinisa inkqubo yokulawula ukubunjwa, ukuphumeza ngokungqongqo inkqubo, kwaye ungatshintshi iiparameters zokubumba ngokuthanda ukuqinisekisa ukuqhubeka kwenkqubo yokubumba.
