Ukucoca ngokwenziwayinkqubo yokususa iziphene zomphezulu we-forging ngoomatshini okanye ngeendlela zekhemikhali.Ukuze kuphuculwe umgangatho womgangatho we-forgings, uphucule iimeko zokusika ukukhwabanisa kunye nokuthintela iziphene zomhlaba ekwandiseni, kuyafuneka ukuba uhlambulule umphezulu weebhilidi kunye nokukhwabanisa nangaliphi na ixesha kwinkqubo yokubumba.
Ukuze kuphuculwe umgangatho womphezulu weforgings, ukuphucula iimeko zokusika zeforgingskunye nokuthintela iziphene zomhlaba ekwandiseni, kuyafuneka ukuba uhlambulule indawo yeebhilidi kunyeforgingsnangaliphi na ixesha kwiinkqubo yokubumba. Iintsimbi zentsimbizidla ngokufudunyezwa ngaphambiliukwenzangebrashi yensimbi okanye isixhobo esilula sokususa isikali se-oxide.I-blank kunye nobukhulu becandelo elikhulu inokucocwa ngenaliti yamanzi yoxinzelelo oluphezulu.Izikali kwi-forgings ezibandayo zingasuswa ngokuchola okanye ukuqhunyiswa (i-pellets).I-nonferrous alloy oxide scale incinci, kodwa ngaphambi nasemva kokufota ukucoca ukucocwa, ukufumanisa ngexesha kunye nokususwa kweziphene zomhlaba.Iziphene ezingaphezulu kwebillet okanye i-forgings ikakhulu ibandakanya iintanda, ukugoba, imikrwelo kunye nokubandakanywa.Ukuba ezi ziphene azisuswanga ngexesha, ziya kuba nemiphumo emibi kwinkqubo yokuqulunqa elandelayo, ngakumbi kwi-aluminium, i-magnesium, i-titanium kunye ne-alloys yazo.Iziphene ezivezwe emva kokucholwa kwe-alloy forgings non-ferrous alloy zicocwa ngokubanzi ngeefayile, i-scrapers, i-grinders okanye izixhobo ze-pneumatic.Iziphene zokubumba intsimbi zicocwa ngokucholwa, ukuqhushumba kwesanti (ukudubula), ukudubula ukudubula, i-roller, i-vibration kunye nezinye iindlela.

Ukucoca i-Acid

Ukususwa kweeoksidi zetsimbi ngokusabela kweekhemikhali.Kwi-forgings encinci kunye ne-medium-sized forgings idla ngokulayishwa kwibhasikithi kwiibhetshi, emva kokususwa kweoli, i-pickling corrosion, ukuhlanjululwa, ukumisa kunye nezinye iinkqubo.Indlela ye-pickling ineempawu eziphezulu zokuvelisa, umphumo wokucoca kakuhle, akukho deformation of forgings kunye nesimo esingathinteliyo.I-Pickling chemical reaction process ngokuqinisekileyo iya kuvelisa iigesi eziyingozi, ngoko ke, igumbi lokukhetha kufuneka libe nesixhobo sokukhupha.Ukuchola iintsimbi ezahlukeneyo kufuneka ukhethe i-asidi eyahlukeneyo kunye nomlinganiselo wokubunjwa ngokweempawu zetsimbi, kwaye wamkele inkqubo yokuchola ehambelanayo (ubushushu, ixesha kunye nendlela yokucoca).

Ukuqhushumba kwesanti (ukudubula) kunye nokudubula ukucoca ukuqhuma
Ngomoya ocinezelweyo njengamandla okudubula kwesanti (ukudubula), yenza isanti okanye isithonga sentsimbi sivelise intshukumo enesantya esiphezulu (i-sandblasting yokusebenza ngoxinzelelo lwe-0.2 ~ 0.3Mpa, i-0.5 ~ 0.6Mpa) i-jet ukuya kwindawo yokubumba ukubetha isikali se-oxide.Ukudutyulwa kokudubula kwenziwa ngesantya esiphezulu (2000 ~ 30001r/min) amandla ajikelezayo e-centrifugal ye-impeller, intsimbi yadutyulwa kumphezulu wobumbi ukuwisa isikali se-oxide.Uthuli lwe-Sandblasting, ukusebenza kakuhle kwemveliso ephantsi, iindleko eziphezulu, ezisetyenziselwa iimfuno ezikhethekileyo zobugcisa kunye nezinto ezikhethekileyo zokubumba (ezifana nensimbi engenasici, i-titanium alloy), kodwa kufuneka ithathe amanyathelo obugcisa okususa uthuli.I-shot peening icocekile ngokwentelekiso, kukwakho nezingeloncedo kwimveliso ephantsi kunye neendleko eziphezulu, kodwa umgangatho wokucoca uphezulu.Ukudubula kwe-shot kusetyenziswa ngokubanzi ekusebenzeni kwayo okuphezulu kunye nokusetyenziswa okuphantsi.
Ukudubula ukukrola kunye nokudubula okuqhumayo kucoceke, kwangaxeshanye, kutshitshise isikali se-oxide, ukwenza umphezulu wokwenza umsebenzi ube lukhuni, kuyanceda ukuphucula ukuxhathisa ukudinwa kwamalungu.Kuba forgings emva kokucima okanye ukucima kunye nonyango tempering, isiphumo umsebenzi lukhuni kubaluleke ngakumbi xa usebenzisa ubungakanani obukhulu shot steel, ukuqina kunganyuswa nge-30% ~ 40%, kwaye ubukhulu umaleko lukhuni ingafikelela 0.3 ~ 0.5mm.Kwimveliso ngokwezinto eziphathekayo kunye neemfuno zobugcisa bokubumba ukukhetha izinto ezahlukeneyo kunye nobukhulu beqhekeza lensimbi.Ukusetyenziswa kokudubula kwesanti (ukudutyulwa) kunye nendlela yokudubula ukucoca i-forging, iintanda zomphezulu kunye nezinye iziphene zinokuthi zigqunywe, kulula ukubangela ukubhaqa okulahlekileyo.Ke ngoko, kuyafuneka ukuba kusetyenziswe ubhaqo lweziphene zamagnetic okanye uphononongo lwe-fluorescence (jonga uvavanyo lomzimba kunye neekhemikhali zeziphene) ukujonga iziphene zomphezulu we-forging.

ukuwa
I-forgings, kwi-drum ejikelezayo, idibanisa okanye igaye ukuze isuse isikali se-oxide kunye ne-burr kwi-workpiece.Le ndlela yokucoca isebenzisa izixhobo ezilula kwaye ezifanelekileyo, kodwa ingxolo enkulu.Ifanelekile kwi-forgings encinci kunye nephakathi ezinokuthwala impembelelo ethile kwaye akukho lula ukukhubaza.Ukucoca i-drum ayinayo i-abrasive, yongeza kuphela intsimbi ye-triangular okanye ibhola yensimbi ububanzi be-10 ~ 30mm yokucocwa okungagungqiyo, ngokukodwa ngokungqubana nokususa isikali se-oxide.Enye kukongeza isanti yequartz, iziqwenga zamavili okugaya i-scrap kunye nezinye iziqhumiso, i-sodium carbonate, amanzi anesepha kunye nezinye izongezo, ngakumbi ngokusila ukucoca.

Ukucoca ukungcangcazela
Kwi-forgings exutywe kunye nomlinganiselo othile we-abrasives kunye nezongezelelo, ezibekwe kwisitya sokungcangcazela, ngokushukuma kwesikhongozeli, ukuze i-workpiece kunye ne-abrasive grinding enye nenye, umphezulu we-oxyde forgings kunye ne-burr off.Le ndlela yokucoca ifanelekile ukucocwa kunye nokupolisha kwee-forgings ezichanekileyo ezincinci kunye neziphakathi.
