Isicelo Incazelo ye Umshini Wokushisa Ophakeme Wokuvama Okuphezulu ku-Surface Quenching of Metal Workpieces

Imishini yokushisa yokungeniswa kwe-high-frequency induction isetshenziswa kakhulu ekucimeni okungaphezulu kwezinto zokusebenza zensimbi, njengokucisha kanye nokwenza lukhuni kwekhanda lezinsimbi zokubhoboza, ukucisha izingxenye zamazinyo zamagiya, ukucisha ukushisa okungaphezulu kwamalunga emoto yonke indawo, ama-crankshaft, izinsimbi, njll. . Manje ake sichaze kafushane indlela yokusebenza eyisisekelo yokucisha ingaphezulu. Lapho sibeka ucezu lwensimbi enxebeni le-inductor ngeshubhu yethusi elingenalutho lomshini wokushisa wokungenisa imvamisa ephezulu, ngemva kokudlula inkambu kazibuthe enemvamisa ephezulu eshintshashintshayo yamanje, i-induction yamanje yokushisisa yefrikhwensi efanayo yenziwa ngokushesha ebusweni umsebenzi. Ubuso bengxenye bushiswa ngokushesha, ingaphezulu le-workpiece lingashiswa ngama-degree angu-800 kuya kwangu-1000 ngemizuzwana embalwa, futhi ingxenye ephakathi ye-workpiece isagcinwe eduze nokushisa kwangaphakathi, bese ifafaza ngokushesha amanzi okupholisa. noma cwilisa i-workpiece emafutheni wokucisha ukuze uphole, ukuze ungqimba olungaphezulu lwe-workpiece lufinyelele ubulukhuni bokucisha obufunayo.

Isikhathi eside, ohlelweni lokucisha izinto zokusebenza zensimbi, sisenazo izindlela zendabuko nezivamile, njengokuthi: ukucisha ukushisa kwelangabi, ukucisha indawo yokushisa kwe-electrolyte, ukucisha indawo yokushisa kwe-electrolyte, ukucisha indawo yokushisa nge-laser, ukushisa kwe-electron beam. ukucisha indawo nokunye okuningi. Kodwa-ke, indlela yokuqinisa i-high-frequency induction warming surface inezinzuzo, ngoba okwamanje ishisa futhi ishisa ngokushesha kunezinye izindlela, futhi ihlanganiswa ngokushesha nokupholisa. Umshini wokushisa we-high-frequency induction heat ungaletha ngokushesha ubuso be-workpiece noma insimbi ekushiseni okucishayo, futhi umshini wokushisa we-high-frequency upholisa ngokushesha ngaphandle kokulinda ukushisa ukuze ufinyelele enkabeni, kuphela ubulukhuni bokucisha ubuso buyi-martensite, futhi isikhungo sihlala siyi-plasticity yasekuqaleni engaqediwe, inhlangano enhle yokuqina (noma i-annealed, normalized and quenched and tempered organization).
