Mokhoa oa ho tima bokahare ba bophara bo ka hare ba likarolo tse nyane tsa lesoba ka lisebelisoa tse futhumatsang tsa maqhubu a phahameng haholo
Lisebelisoa tse futhumatsang tse phahameng tsa maqhubu li ka sebelisa li-inductors tsa spiral terata bakeng sa ho thatafatsa holim’a bophara ba likarolo tse nyane tsa lesoba: thepa ea karolo e nyane ea lesoba ke tšepe ea 45. Sebaka se ka hare sa sekoti se nang le bophara ba 20mm se hloka mocheso o phahameng oa maqhubu a ho futhumatsa le ho tima, botebo ba lera le thata ke 0.8-1.0mm, ‘me boima ke 50-60HRC. E fumanoa ka tlhahiso ea hore ho thata ho futhumatsa le ho tima likoti tse nyenyane tse nang le bophara ba 20mm ho sebelisa lisebelisoa tse phahameng tsa maqhubu. Ka lehlakoreng le leng, li-inductors tse tloaelehileng tsa lesoba ha li bonolo ho li etsa, ‘me ho thata ho kenya limakete; ka lehlakoreng le leng, ho sa tsotellehe hore na inductor e sebelisoa ho fafatsa metsi, E ntse e sebelisa mokhoa o khethehileng oa ho futhumatsa jete oa jete oa metsi, o nang le phello e mpe ea ho tima le ho pholisa holim’a workpiece, ‘me ho thatafala ha lesoba le ka hare ha hoa lekana, ho ke keng ha khoneha. kopana le litlhoko tsa tekheniki.
Mocheso o phahameng oa maqhubu a ho futhumatsa le ho tima motlakase e ne e le leqeba la inductor ho tloha ka tube e hloekileng ea koporo e bophara ba 4mm, e nang le bophara ba ka ntle ba 16mm, sekontiri sa 7mm, kakaretso ea 3, le ho phalla ha metsi a pholileng ka hare. Ha e sebelisoa, ho fumanoa hore inductor ha e thata feela ho e etsa, ‘me metsi a pholileng ha a phalle hantle, e le hore mocheso o futhumatsang o se ke oa lekana. Ka mor’a ho tima le ho futhumatsa, e nosetsoa le ho pholile. Ha e phethehe, kahoo ho thatafala ha workpiece ka mor’a ho tima ha hoa lekana, e hlōlehang ho finyella litlhoko tsa theknoloji.
Kamora liphuputso tse ngata, ho ile ha ntlafatsoa mochini oa terata oa spiral terata mme oa etsoa ka mokhoa o ikhethileng, ‘me tlhahlobo ea ts’ebetso ea ho tima metsi e ile ea etsoa. Thepa e nka lisebelisoa tse futhumatsang tse phahameng tsa induction. Mekhoa ea ts’ebetso ke e latelang: matla a motlakase ke 380-400V, motlakase oa motlakase ke 1.2-1.5A, anode hona joale ke 3-5A, anode voltage ke 7-9kV, tanka ea potoloho ea motlakase ke 6-7kV, ‘me nako ea ho futhumatsa ke 2-2.5s. Ha lisebelisoa tse futhumatsang tsa induction tse phahameng li futhumala, mocheso o holim’a sebaka sa mosebetsi oa phahama, ‘me metsi a pota-potileng a etsoa mouoane ho etsa filimi ea mouoane e tsitsitseng e pota-potileng workpiece, e leng e arolang mosebetsi ho tloha metsing a pholileng a phallang. Filimi ea mouoane e na le mocheso o fokolang oa mocheso ‘me o phetha karolo ea ho kenya letsoho le ho boloka mocheso,’ me mocheso oa workpiece o phahama ka potlako ho mocheso o timang ‘me oa tima. Ka nako ena, matla a khaotsoe, filimi ea mouoane e holim’a setsi sa mosebetsi e robehile, mosebetsi oa ho sebetsa o pholile ka potlako ke metsi a pholileng a phallang, phetoho ea sebopeho e phethiloe, ‘me bokaholimo ba mosebetsi bo thatafalloa. Liphetho tsa liteko ke tse latelang: boima bo ka hare ba bophara ba lesoba le ka hare ke 55-63HRC, botebo bo thata ba lesela ke 1.0-1.5mm, kabo ea boima bo tšoana, shrinkage ea lesoba e ka bang 0.015-0.03mm, deformation e nyane. , ‘me litlhoko tsa tekheniki li fihletsoe. Ts’ebetso ea tlhahiso ke likotoana tse 200 / h.
Le hoja teko ea ho tima metsi a ka tlas’a metsi ea spiral wire inductor e na le phello e ntle ho tima bophara ba ka hare ho lesoba le lenyenyane, re lokela ho ela hloko lintlha tse latelang tlhahiso:
1. Hobane mohala oa koporo o batla o le mosesaane ebile o thata, sekontiri se ke ke sa e-ba se senyenyane haholo, ho seng joalo ho bonolo ho kopana le ho baka potoloho e khutšoanyane ka mor’a matla; empa haeba sekontiri se le seholo haholo, mocheso o tla be o sa lekane ‘me ho thatafala ha lera le thata ho tla ba ho sa lekane. Palo ea ho chenchana e amana le botenya ba workpiece. Haeba palo ea ho reteleha e le nyane haholo, ho thatafala ha lera le thata ho tla ba ho sa lekane. Haeba ho na le liphetoho tse ngata haholo, impedance ea inductor e tla ba khōlō ‘me phello ea ho futhumatsa e tla fokotseha. Sekhahla sa inductor le palo ea li-turning li lokela ho khethoa ka nepo ho etsa hore ts’ebetso ea ho tima e atlehe.
2. Phello e futhumatsang ea bophara ba terata ea koporo ke 2mm, ‘me mefuta e meng e bonolo ho chesa.
3. Inductor e na le terata e tšesaane ea koporo le ho se tsitse hantle. E tla thothomela tlas’a ketso ea matla a khoheli ka mor’a hore e matlafatsoe. E le ho thibela inductor hore e se ke ea sisinyeha, ho chesa le ho khathala, sesebelisoa sa ho matlafatsa kutlo se etselitsoe ho fokotsa ho thothomela.
