Phapang ke efe pakeng tsa Ho tima maqhubu a phahameng le intermediate frequency quenching?

Molao-motheo oa ts’ebetso oa ho tima maqhubu a phahameng le ho tima maqhubu a mahareng o ts’oana le oa ho futhumatsa ka induction: ke hore, workpiece e behiloe ka har’a inductor, ‘me inductor hangata ke tube e se nang letho e kenyang maqhubu a mahareng kapa maqhubu a phahameng a feto-fetohang. (1000-300000Hz kapa ho feta). Maqhubu a matla a khoheli a fapanyetsanang a hlahisa maqhubu a ts’oanang a ts’ebetso. Kabo ea hona joale e susumelitsoeng ho workpiece ha e lekane, e matla holim’a metsi, empa e fokola haholo ka hare, ‘me e haufi le 0 bohareng. Phello ena ea letlalo e sebelisoa. , bokaholimo ba workpiece bo ka futhumatsoa ka potlako, mocheso oa holim’a metsi o nyolohela ho 800-1000 ℃ ka metsotsoana e seng mekae, ‘me mocheso oa karolo ea mantlha o monyenyane haholo.

Leha ho le joalo, nakong ea ts’ebetso ea ho futhumatsa, ho ajoa ha motlakase o kentsoeng mosebetsing ha ho lekane, ‘me phello ea ho futhumatsa e hlahisoang ke maqhubu a fapaneng a hona joale le eona e fapane. Joale, phapang lipakeng tsa ho tima maqhubu a phahameng le ho tima maqhubu a mahareng a tla:

1. High frequency quenching

Maqhubu a hajoale a pakeng tsa 100 le 500 kHz

Lera le thata le sa tebang (1.5 ~ 2mm)

Melemo kamora ho tima khafetsa khafetsa: boima bo phahameng, sesebelisoa sa mosebetsi ha se bonolo ho ka oxidized, deformation e nyane, boleng ba ho tima bo botle, ‘me katleho ea tlhahiso e phahame.

Ho tima maqhubu a phahameng haholo ho loketse likarolo tse sebetsang tlas’a maemo a khohlano, joalo ka likere tse nyane le li-shafts (lisebelisoa tse sebelisoang ke 45 # tšepe, 40Cr)

2. Intermediate frequency quenching

Maqhubu a hajoale ke 500 ~ 10000 Hz

Lera le thatafalitsoeng le tebile (3 ~ 5mm)

Ho tima maqhubu a mahareng ho loketse likarolo tse tlas’a meroalo e sothehileng le khatello, joalo ka li-crankshafts, likere tse kholo, li-spindle tsa mochini o silang, joalo-joalo (lisebelisoa tse sebelisoang ke 45 # tšepe, 40Cr, 9Mn2V le graphite ea ductile.

Ka bokhutšoanyane, e ‘ngoe ea liphapang tse totobetseng pakeng tsa ho tima maqhubu a phahameng le ho tima maqhubu a mahareng ke phapang ea botenya ba mocheso. Ho tima maqhubu a phahameng ho ka thatafatsa bokaholimo ka nako e khuts’oane, sebopeho sa kristale se setle haholo, ‘me sebopeho sa sebopeho se nyane. E-ba nyenyane.
