Mokhoa o phahameng oa phekolo ea mocheso oa mocheso bakeng sa lithipa tsa kichine tse se nang tšepe tse tingoeng ke lisebelisoa tse tima tsa maqhubu a phahameng

Thepa ea thipa ea kichineng ea tšepe e sa hloekang ke 3Cr13 kapa 4Cr13, ‘me boholo ba kantle ke 180mmX80mmX2.5mm. Ka mor’a ho sila ka thata ho 0.8-0.9mm, moeli oa ho itšeha o kenngoa ts’ebetsong ea ho tima mocheso ka sebōping sa ho tima mocheso o phahameng oa maqhubu. Ka mor’a ho tima, e finyella litlhoko tse latelang: boima ba 50-56HRC, sebaka se thata ≥25mm, kabo ea boima bo tšoanang, le deformation ≤2mm.

1) Mekhahlelo ea motlakase ea sesebelisoa. Matla a ho kenya ke 380V, anode voltage ke 7.5kV, anode current ke 2.5A, tanka ea tanka ke 5kV, grid ea hona joale ke 0.6A, ‘me maqhubu ke 250kHz.

2) Ho tima mokhoa oa ho futhumatsa. Sebōpi se timang maqhubu a phahameng se sebelisoa bakeng sa ho tima. Inductor e khethehileng e lokela ho etsoa. Thipa ea kichineng e lokela ho behoa sebakeng se loketseng ho inductor. Lebelo la ho futhumatsa ha induction hangata ke 200-400 ℃/s. Austenitization e phetheloa hang hang, ‘me ha ho hlokahale ho boloka mocheso. . Mocheso oa ho futhumatsa o timang ke 1050-1100 ℃, ‘me se pholileng ke oli. Mocheso oa mocheso ho 200-220 ℃.

Ka har’a mefuta e fapaneng ea 180mm X25mm sebakeng se thata, ho thatafala ka mor’a ho tima le ho halefa ke tsohle> 50HRC, ‘me boima bo batla bo tšoana. Lipontšo tsohle li ka fihlela litlhoko tsa tekheniki.
