1.Kutheni ukucima kunye nokugoba kwenzeka?
Ukugoba okucinyiweyo kwenzeka ngexesha lokufudumeza kunye nokucima ukupholisa. Okwenzekayo ekufudumezeni kukugoba, kwaye isizathu sokugoba ekupholiseni kukupholisa okungalinganiyo.Isantya esikhawulezayo sokupholisa, kokukhona kunokwenzeka ukwenza ukupholisa kungalingani, ukuze ukupholisa kwamanzi eyona nto ithanda ukucima kunye nokugoba, ilandelwa yioli, ukuhlamba ubushushu, umoya (umyalelo wokupholisa ngokuthe ngcembe uncitshiswe.Ukuba ukupholisa akulingani, icala lokupholisa ngokukhawuleza liqala ukugoba, kwaye xa yonke inxalenye ipholile, iba yi-convex.
Kwakhona, ukusebenzisa inkxaso engafanelekanga ekufudumezeni kuya kubangela ukugoba okucimayo, kunye noxinzelelo lokuqhuba luya kubangela ukugoba kokucima.
2. Iziphatha njani ukugoba okucinyiweyo?
Ngenxa yokuba icala lokuqala lokupholisa ekucimeni licala eliqinileyo, eli cala liba yi-convex.
3. Indlela yokupholisa kunye nokucima kunye nokugoba
Njengoko kukhankanyiwe ngaphambili, iindawo zokugoba ezicinyiweyo zibangelwa ukupholisa okungalinganiyo. Ngokufanayo, ukuba indawo eshushu ayipholiswanga ngokulinganayo, icala lokuqala lokupholisa liba yi-convex, ngomzuzu wokucima, icala lokuqala lokupholisa liba yi-concave, kwaye xa lonke inxalenye ipholiswe ngokupheleleyo, yona ibe yiconvex.Umfanekiso wesi-3 kunye noMzobo 2 ubonisa olu lwalamano.Olu tshintsho lwenzeka xa kukho umahluko weqondo lobushushu phakathi kwecala lokuqala lokupholisa kunye necala lokupholisa elicothayo, kunye neendawo ezibhityileyo ezingemiyo. lo mahluko wobushushu.Akukho ukuguqulwa okunjalo, kwaye icala lokuqala lokupholisa ligcina imilo ye-concave ingatshintshanga.Isenzeko sokubuyisela umva kufuneka sibe neqondo elithile lobunzima bodonga, ubukhulu bodonga malunga ne-15 ~ 20 mm ngaphezu kweyoqobo ukuze ivele le nto yokubuyisela umva.
Ngamafutshane, iindawo zokucinywa ngokubanzi zezalo mcimbi. Kwaye kutheni icala lokupholisa ngokukhawuleza liconvex? Kungenxa yokuba icala elapholisa iikhontrakthi zokuqala, ligcina icala lokupholisa ngokucothayo licinezelekile. Ngenxa yesi sizathu, icala lokupholisa ngokukhawuleza lifutshane kunelo ubude obufanelekileyo kwelo qondo lobushushu, kwaye kule meko, xa yonke inxalenye ipholile, icala lokupholisa liyenyuka kuqala, ngelixa icala lokupholisa elicothayo li-concave.Xa yonke inxalenye ingafudumala, kodwa icala elinye kuphela lokufudumeza, ukuba kuphela umphezulu uphole ngokukhawuleza phantsi, indawo eshushu iya kuba yi-concave.Ngenxa yokuba elinye icala liyafudumala, kungakhathaliseki ukuba eli cala lipholile kangakanani, licotha. kunecala elingatshisiyo.Icala elingenakufudumala lilingana nokupholisa ngesantya esingenasiphelo, ngoko ke ukupholisa ngokukhawuleza, ukwenzela ukuba icala elingenakufudumala libe yi-convex.Ngamanye amazwi, icala lokupholisa ngokukhawuleza liba yi-convex.
Ukufudumeza esebenzisa lo mgaqo kuthiwa ukufudumeza linear, leyo yindlela ukugoba angqingqwa iipleyiti zentsimbi. Oko kukuthi, i-oksijini-acetylene ilangatye umlomo wombhobho kuphela kwipleyiti eshinyeneyo ukuya kumgca ukufudumeza ngokukhawuleza, ukufudumeza kunye nokupholisa amanzi.Jika ipleyiti yentsimbi. phezulu kwi-engile echanekileyo kumgca othe tye.Oko kukuthi, indlela yokufudumeza enjalo kufuneka igobe.Kucacile ukuba oku kufudumala kufuneka kube ngaphantsi kweqondo lokushisa elibalulekileyo.Kuya kuba kubi ukucinywa.Ukuba ubushushu bokufudumala abulawulwa kakuhle. kunye nokucima, ukwandiswa kwe-martensite kucinezela i-warping yepleyiti, emva koko iziphumo ezingentla azifumaneki.Imela yaseJapan isebenzisa i-warping ecinyiweyo.Nangona ipholile emva kokufudumeza, i-blade yokupholisa ngokukhawuleza iphuma ngenxa yokuba i-blade ibhityile kwaye umva unzima, kwaye ukupholisa akulingani.Apha, umva wemela uconcave kwaye uba warped.Plus nokwandiswa martensite ekucimeni, warping
