Txoj cai ua haujlwm rau cov khoom siv hluav taws xob ntau zaus

1. Cov neeg ua haujlwm ntawm cov khoom siv hluav taws xob ntau zaus yuav tsum tau kawm thiab tsim nyog ua ntej lawv tuaj yeem ua haujlwm.

2. Thaum lub tshuab cuab yeej pib, thawj zaug tig rau lub tshuab dej, tom qab ntawd tig lub zog ntawm lub tshuab cuab yeej, tig rau ntawm qhov hluav taws xob ntawm thawj filament thiab lub thib ob filament, tig rau lub siab voltage, thiab kho cov tso zis voltage knob kom qhov voltage mus txog qhov yuav tsum tau ua hauj lwm voltage. (Kev kaw tseg: Cov lus qhia tawm qhov hluav taws xob siab rov qab mus rau xoom, thiab qhov thim rov qab rov qab los kaw hauv lem. Cov dej xa dej tau ncua rau 30 feeb kom kaw)

3. Nruab lub ntsuas cua sov yam tsis tau txuas nrog lub hwj huam mov. Kev sib txuas ntawm lub nplhaib-txo lub nplhaib thiab lub sensor yuav tsum muaj kev sib cuag zoo. Yog tias muaj oxide, siv daim ntaub emery lossis lwm txoj hauv kev los tshem nws. Kho qhov sib txawv thiab qhov siab ntawm lub sensor thiab cov khoom ua haujlwm, thiab ua kom nws sib npaug rau sab phaj. (uas yog, kho txoj haujlwm hauv X, Y, Z cov lus qhia, thiab sau cov ntaub ntawv)

4. Qhov nruab nrab ntawm cov khoom siv quenching siab yog feem ntau yog dej thiab ib qho concentration ntawm quenching kua, thiab qhov kub ntawm qhov nruab nrab quenching yog tsawg dua los yog sib npaug li 50 ° C; rau qee cov khoom ua haujlwm uas tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua, nws raug tso cai los kho qhov concentration ntawm cov kua quenching kom tsim nyog, tab sis nws yuav tsum tau xyuas kom meej tias qhov hardness yog tsim nyog thiab tsis muaj quenching tawg.

5. Ua ntej kev tsim khoom, lub quenching kua nozzle yuav tsum tau tas, thiab tsis muaj qhov pom tseeb ua npuas ncauj hauv cov kua quenching.

6. Cov txheej txheem hardened zoo qhov tob ntawm cov khoom siv high-frequency quenching yuav tsum tau coj mus kuaj thiab ntsuas raws li qhov yuav tsum tau ua thiab cov qauv tsim nyog hauv cov txheej txheem kev kho cua sov kom ua tau raws li cov kev cai.

7. Tus neeg teb xov tooj yuav tsum tau kho cov txheej txheem tsis raws li qhov yuav tsum tau ua ntawm cov txheej txheem, sib txawv sensors, thiab sib txawv quenching txoj kev (taw-taw tes los yog nruam). Txhua batch ntawm qhov chaw yuav tsum tau quenched 1-2 daim ua ntej ntau lawm. Tom qab kev sim, tsis muaj cov kab nrib pleb siab quenching, thiab qhov hardness thiab qhov tob ntawm txheej hardened yog tsim nyog ua ntej ntau lawm.

8. Thaum lub sij hawm tsim cov txheej txheem, tus neeg teb xov tooj yuav tsum tau soj ntsuam qhov hloov pauv ntawm qhov hloov pauv ntawm lub tshuab cuab yeej, qhov kub thiab txias, qhov chaw cua sov thiab txoj hauj lwm hloov pauv los ntawm qhov sib thooj thiab qhov sib txawv ntawm lub workpiece thiab lub sensor. Lub peev xwm txias hloov los ntawm qhov deflection ntawm cov yeeb nkab tshuaj tsuag yuav tsum tau hloov kho txhua lub sijhawm yog tias tsim nyog.

9. High-frequency quenched qhov chaw yuav tsum tempered nyob rau hauv lub sij hawm, feem ntau nyob rau hauv 2 teev tom qab quenching. Rau cov pa roj carbon steel, alloy steel thiab cov khoom sib txawv thicknesses nrog cov ntsiab lus carbon ntawm ≥ 0.50%, lawv yuav tsum tau tempered li ntawm 1.5 teev.

10. Workpieces uas yuav tsum tau reworked yuav tsum tau induction normalized ua ntej rework kom tsis txhob tawg los ntawm re-quenching. Cov workpieces tsuas yog tso cai rov ua dua ib zaug.

11. Thaum lub sij hawm tsim khoom, tus neeg teb xov tooj yuav tsum ua tsis pub tsawg tshaj peb qhov kev ntsuam xyuas hardness (ua ntej, thaum lub sij hawm, thiab qhov kawg ntawm workpiece).

12. Thaum lub xeev tsis zoo tshwm sim thaum lub sijhawm ua haujlwm, lub zog ua haujlwm yuav tsum raug muab tua tam sim ntawd, thiab tus thawj saib xyuas kev cob qhia yuav tsum raug qhia rau tus thawj saib xyuas kev cob qhia kom kho lossis kho.

13. Lub chaw khiav hauj lwm yuav tsum tau ua kom huv si, qhuav thiab tsis muaj dej, thiab yuav tsum muaj cov roj hmab insulating qhuav ntawm lub pedal kev khiav hauj lwm kom muaj kev nyab xeeb ntawm tus neeg teb xov tooj.
