Indlela yokucima umphezulu we-diameter yangaphakathi yeendawo ezincinci zomngxuma nge izixhobo zokufudumeza ezikwi-frequency ephezulu

Izixhobo zokufudumeza eziphezulu ze-high-frequency induction zingasebenzisa i-spiral inductors ye-spiral inductors yokuqina komphezulu we-diameter yangaphakathi yeendawo ezincinci zomngxuma: izinto eziphathekayo zengxuma encinci yintsimbi engama-45. Ububanzi obungaphakathi bomngxuma kunye nobubanzi be-20mm bufuna ukufudumeza kwe-high-frequency induction kunye nokucima, ubunzulu boluhlu oluqiniweyo ngu-0.8-1.0mm, kwaye ubunzima buyi-50-60HRC. Kufunyenwe kwimveliso ukuba kunzima ukutshisa kunye nokucima imingxuma encinci kunye nobubanzi be-20mm usebenzisa izixhobo zokungeniswa kwe-high-frequency induction. Ngakolunye uhlangothi, i-inductors yangaphakathi yomngxuma eqhelekileyo ayilula ukwenza, kwaye kunzima kakhulu ukufaka imagnethi; kwelinye icala, kungakhathaliseki ukuba i-inductor isetyenziselwa ukutshiza amanzi, isasebenzisa indlela ekhethekileyo yokupholisa ibhatyi yejethi yamanzi, enefuthe elibi lokucima kunye nokupholisa kwi-workpiece, kunye nobunzima bomngxuma ongaphakathi awulingani, ongenakho. ukuhlangabezana neemfuno zobugcisa.

I-high-frequency induction heat and quenching inductor isetyenziselwa i-inductor isilonda esivela kumbhobho wobhedu ococekileyo kunye nobubanzi be-4mm, kunye nobubanzi obungaphandle be-16mm, i-pitch ye-7mm, i-3 iyonke ijika, kunye nokupholisa kwamanzi agelezayo ngaphakathi. Ekusetyenzisweni, kufunyenwe ukuba i-inductor ayinzima nje ukuyivelisa, kwaye amanzi okupholisa awahambi kakuhle, ukwenzela ukuba ukushisa kushushu kungalingani. Emva kokucima nokufudumeza, iyankcenkceshelwa kwaye ipholiswe. Ukungagqibekanga, ngoko ke ubunzima bomsebenzi emva kokucima abulingani, obungaphumeleli ukuhlangabezana neemfuno zobugcisa.

Emva kophando oluninzi, i-spiral wire inductor yaphuhliswa kwaye yenziwa ngokwezifiso, kunye ne-spiral wire inductor entywiliselweyo yovavanyo lwenkqubo yokucinywa kwamanzi. Isixhobo sithatha izixhobo zokufudumeza eziphakamileyo. Iiparamitha zenkqubo zimi ngolu hlobo lulandelayo: amandla ombane ombane yi-380-400V, i-grid yangoku yi-1.2-1.5A, i-anode yangoku yi-3-5A, i-anode voltage yi-7-9kV, i-tank circuit voltage yi-6-7kV, kwaye ixesha lokufudumala li-2-2.5s. Xa i-high-frequency induction heat equipment ishushu, iqondo lobushushu bomphezulu we-workpiece liyenyuka, kwaye amanzi ajikelezileyo apheliswe ngumphunga ukuze enze ifilimu yomphunga ezinzileyo ejikeleze i-workpiece, eyahlula i-workpiece kumanzi apholisayo aqukuqelayo. Ifilimu ye-steam inokushisa okungahambi kakuhle kwaye idlala indima yokukhusela kunye nokugcinwa kobushushu, kwaye iqondo lokushisa lomsebenzi likhuphuka ngokukhawuleza kwiqondo lokushisa lokucima kwaye licinywe. Ngeli xesha, amandla anqunyulwa, ifilimu ye-steam phezu kwendawo yokusebenza iphukile, i-workpiece ipholile ngokukhawuleza ngamanzi apholileyo ahambayo, ukuguqulwa kwesakhiwo kugqityiwe, kwaye umphezulu we-workpiece unzima. Iziphumo zovavanyo zimi ngolu hlobo lulandelayo: ubunzima obungaphakathi bomngxuma wangaphakathi ngu-55-63HRC, ubunzulu bomaleko obunzima yi-1.0-1.5mm, ukusabalalisa ubunzima bufanayo, ukucutha komngxuma malunga ne-0.015-0.03mm, ukuguqulwa kuncinci. , kunye neemfuno zobugcisa zihlangatyezwa. Ukusebenza kakuhle kwemveliso ngamaqhekeza angama-200 / h.

Nangona uvavanyo lokucinywa kwamanzi aphantsi komhlaba lwe-spiral wire inductor lunesiphumo esihle ekucinyweni kwe-diameter yangaphakathi yomngxuma omncinci, kufuneka sinikele ingqalelo kula manqaku alandelayo kwimveliso:

1. Ngenxa yokuba ucingo lobhedu luncinci kwaye luqinile, i-pitch ayikwazi ukuba yincinci kakhulu, ngaphandle koko kulula ukudibanisa kunye nokubangela isiphaluka esifutshane emva kombane; kodwa ukuba i-pitch inkulu kakhulu, ukufudumeza kuya kungalingani kwaye ukuqina komgangatho oqinileyo kuya kungalingani. Inani lokujika lihambelana nobukhulu bomsebenzi womsebenzi. Ukuba inani lokujika lincinci kakhulu, ukuqina komgangatho oqinileyo buya kungalingani. Ukuba kukho ukujika okuninzi, i-impedance ye-inductor iya kuba nkulu kwaye umphumo wokufudumeza uya kuncipha. I-pitch ye-inductor kunye nenani lokujika kufuneka likhethwe ngokufanelekileyo ukwenza umsebenzi wokucima uphumelele.

2. Impembelelo yokufudumala yocingo lobhedu ububanzi yi-2mm, kunye nezinye iintlobo zilula ukutshisa.

3. I-inductor inocingo oluncinci lobhedu kunye nokungahambi kakuhle. Iya kungcangcazela phantsi kwesenzo sommandla wamagnetic emva kokuba inikwe amandla. Ukuze ukhusele i-inductor kwi-vibration, i-ignition and burnout, isixhobo sokuqinisa inzwa yenzelwe ukunciphisa ukungcangcazela.
