Cov khoom siv tseem ceeb ntawm lub Hoobkas duab los qhia yog ib qho -ib lub tshuab, thiab cov khoom tseem ceeb ntawm ib qho -ib lub tshuab yog cov corrugated roller. Txawm li cas los xij, qhov teeb meem ntawm corrugated rollers tau ua rau muaj kev ntxhov siab tas li rau cov tuam txhab thiab cov neeg siv, tshwj xeeb tshaj yog rau cov tuam txhab uas kho cov corrugated rollers, vim nws feem ntau ua rau cov chais yaig dheev tawg rau hauv cov hniav thaum lub sij hawm sib tsoo, uas tej zaum yuav ua mob rau cov neeg ua haujlwm. Cov kab lus no yog tsom rau kev txheeb xyuas seb cov corrugated cov kab nrib pleb yog tsim li cas.
Kev kho cua sov tsis raug
Qhov teeb meem tawg tshwm sim los ntawm kev kho cua sov tsis zoo yog qhov loj tshaj plaws, thiab nws yuav tsum tau ua kom poob thaum lub sijhawm kho dua tshiab. Cov ntaub ntawv corrugated feem ntau yog ua los ntawm 35CrM thiab 42CrM. Lawv txoj kev kho cua sov yog qhov nruab nrab ntawm qhov nruab nrab- zaus quenching, nrog qhov siab tshaj plaws ntawm HRC 55-60. Qhov siab dua qhov hardness, lub neej ua haujlwm ntev. Yog tias cov txheej txheem kho cua sov tsis tsim nyog, ob hom quenching tawg yuav tshwm sim: cov kab nrib pleb ntev thiab cov kab nrib pleb.
Muaj lwm qhov ua rau muaj kev tsim ntawm ob hom kab nrib pleb - ncua kev tawg: qhov no tshwm sim thaum cov txheej txheem tempering tsis raws sij hawm lossis tsis txaus, uas ua rau muaj kev ntxhov siab ntau ntxiv vim qhov hloov pauv ntawm cov qauv nrog ntau qhov seem ntawm austenite.
Kev daws: Ntev npaum li cov txheej txheem kho cua sov yog qhov tseeb thiab qhov hardness ntawm corrugated rau cov hniav nto nyob hauv thaj tsam ntawm HRC 55-60, cov kab nrib pleb tuaj yeem zam tau.
2. Kev teeb tsa tsis raug
Kev teeb tsa ntawm corrugating rolls thiab nias rolls ntawm ib zaug -ib lub tshuab, nrog rau kev ua haujlwm kom raug, yuav txiav txim ncaj qha seb cov corrugating yob yuav tsim cov kab nrib pleb lossis poob cov hniav lossis cov hniav tawg.
Kev tsom xam kom ntxaws: Vim yog qhov tsis txaus siab lossis siab dhau ntawm ob qho kawg ntawm cov menyuam nias, nws yuav ua rau lub zos detachment thiab cov hniav tawg ntawm ob qho tag nrho ntawm cov menyuam corrugating qis. Txawm hais tias cov menyuam corrugating yog tsim los tshiab los yog kho dua tshiab, muaj qhov tsis zoo nyob rau hauv cov menyuam corrugating sab saud. Yog hais tias lub axis ntawm lub sab sauv corrugating cov menyuam tsis sib npaug mus rau lub axis ntawm lub qis corrugating cov menyuam, lub zos txias ua hauj lwm hardening yuav tshwm sim (tsis sib npaug zog rau tag nrho cov hniav dav cheeb tsam ua rau muaj kev ntxhov siab concentration), thiab nyob rau hauv cov kev sib xyaw ua ke ntawm lattice distortion kev ntxhov siab thiab kev kho cua sov tsis xws luag, cov kab nrib pleb yuav tsim, uas tshwm sim nyob rau hauv ib tug S{2}}zoo li tus qauv ntawm lub corrugating. Nyob rau lub sijhawm no, ob sab ntawm daim ntawv corrugating rau cov ntawv qhia rov qab -kev taw qhia asymmetrical corrugations.
3. Kev sib tsoo tsis raug
Kev sib tsoo cov kab nrib pleb uas yog tshwm sim los ntawm kev kub nyhiab yog cov tsim los ntawm kev sib tsoo kub hnyiab thiab yog cov keeb kwm thib ob martensite. Their characteristic is perpendicular to the grinding marks, manifested as irregular fine, dense, shallow and sparse or dense network-like cracks beneath the surface layer of the tooth surface. Qee qhov sib tsoo tawg tsis tshwm sim rau sab nrauv tab sis yog qhov tsis xws luag uas nyuaj rau kev kuaj pom los ntawm qhov muag liab qab hauv qab txheej txheej. Cov kev taw qhia ntawm cov kab nrib pleb yog feem ntau perpendicular mus rau kev sib tsoo cov kev taw qhia los yog nyob rau hauv ib tug network qauv. Kev tsim cov kab nrib pleb feem ntau tshwm sim ib txhij nrog qhov kub. Kev sib tsoo kub tsis yooj yim kom zam tau vim tias cov cua sov tsim thaum lub sij hawm sib tsoo yog 800-1200 degree, thiab cov cua sov absorbed los ntawm kev sib tsoo log account rau 12%, thaum tshav kub absorbed los ntawm kev sib tsoo nyiaj rau 4%, thiab cov cua sov seem yog tag nrho absorbed los ntawm corrugated yob.
Kev daws kom tsis txhob hlawv:
Txhim kho cov nyhuv txias
(a) Siv siab -siab thiab loj- ntws txias. Qhov no tsis tsuas yog txhim kho cov nyhuv txias tab sis kuj tseem ua rau lub qhov dej ntws tawm ntawm qhov sib tsoo lub log, tiv thaiv qhov khoob ntawm kev txhaws los ntawm cov txheej txheem txiav.
(b) Txhawm rau txo cov txiaj ntsig ntawm qhov siab -siab adhering airflow ntawm qhov siab ntawm -ceev rotating sib tsoo log, cua baffles yog ntsia thiab coolant yog sprayed los ntawm ntau yam kev taw qhia mus rau lub sib tsoo cheeb tsam, kom ntseeg tau tias lub coolant yuav smoothly mus txog qhov sib tsoo cheeb tsam.
(c) Siv alkaline coolant.
2. Kev xaiv ntawm kev sib tsoo tsis cuam tshuam nrog nce kev sib hloov ceev ntawm lub log sib tsoo thiab lub corrugator. Thaum lub sij hawm sib tsoo cov txheej txheem ntxhib, qhov sib tsoo qhov tob thiab qhov ceev ntawm lub corrugator yuav tsum tau nce, uas yuav txhim khu cov qib ntawm cov yas deformation thiab yog li ua kom cov roughness. Thaum kawg, siv qhov sib tsoo me me lossis tsis muaj qhov sib tsoo tuaj yeem txhim kho qhov chaw tiav.
3. Kev txhim kho kev sib tsoo ntawm kev sib tsoo lub log: Lub abrasive thiab binder ntawm kev sib tsoo lub log yog qhov tseem ceeb heev hauv kev sib tsoo ntawm cov menyuam corrugated. Cov roj hmab- sib tsoo log tuaj yeem tiv thaiv qhov kub hnyiab vim tias cov nplaum no muaj qee yam elasticity. Thaum cov khoom abrasive raug txiav quab yuam ntau dhau, lawv yuav cia li thim rov qab, txo qhov sib tsoo qhov tob. Tsis tas li ntawd, kev kho ntawm kev sib tsoo log kuj tseem ceeb heev. Ntawd yog, qhov ntse ntawm lub log sib tsoo nyob ntawm qhov sib tsoo qhov tob thiab qhov ceev ntawm cov menyuam corrugated.
Hauv cov ntsiab lus, cov kab nrib pleb uas tsim los ntawm cov corrugated yob feem ntau yog ib qho teeb meem ntsig txog cov txheej txheem kho cua sov. Txawm hais tias lawv yog cov kab nrib pleb ntev lossis cov kab nrib pleb, lawv feem ntau nkag mus rau cov kab nrib pleb uas ua rau cov corrugated yob poob los yog tawg cov hniav. Qhov thib ob, kev teeb tsa tsis raug thiab kev ua haujlwm tsis raug tuaj yeem ua rau muaj qhov txias txias - ua haujlwm hardening lattice distortion kev ntxhov siab thiab quenching kev ntxhov siab, ua rau cov hniav poob lossis tawg. Cov txheej txheem sib tsoo tsis raug yuav ua rau hlawv cov kab nrib pleb, tab sis lawv yog qhov ntiav thiab sib cais thiab yuav tsis ua rau cov kab nrib pleb, thiab yog li yuav tsis ua rau cov hniav poob lossis tawg.
