1. Qhov siab ntawm daim ntawv pawg. Raws li pawg qhov siab nce, qhov yuam kev hauv qhov txiav loj nce. Vim tias daim ntawv pawg siab dhau lawm, lub siab ntawm daim ntawv xovxwm yog sib npaug, thiab cov shear tsis kam ntawm cov ntawv pawg yog loj, yog li ua rau cov bending deformation ntawm daim ntawv pawg, thiab cov ntawv txiav yuav tshwm nyob rau sab sauv ntev. ntawm pawg thiab luv luv ntawm qhov qis. Yog li ntawd, nws yog qhov zoo tshaj los tswj qhov siab ntawm cov ntawv txiav hauv qab 100mm.
Qhov thib ob, qhov zoo thiab qhov ntse ntawm lub tshuab txiav. Thaum siv ob lub ntsej muag nqa riam, kev sib txhuam quab yuam thiab txiav quab yuam ntawm daim ntawv pawg ntawm lub ntsej muag ntawm lub tshuab nqa riam raug txo, thiab txiav qhov tseeb yog txhim kho. Cov hniav yog sharpened, txiav tsis kam ntawm cov khoom mus rau txiav riam yog me me thaum txiav, hnav thiab lub zog noj ntawm lub tshuab yog me me, thiab cov khoom txiav yog zoo huv si thiab incision yog du. Ntawm qhov tod tes, yog tias cov hniav ntse ntse tsis ntse, qhov kev txiav zoo thiab txiav ceev yuav txo qis, thiab nws yooj yim dua los rub tawm cov ntawv nyob rau sab saum toj ntawm daim ntawv pawg thaum txiav, ua rau qhov tsis sib xws ntawm lub siab thiab qis. txiav ntug.
Thib peb, lub siab ntawm daim ntawv pawg. Daim ntawv xovxwm yuav tsum tau nias kom nruj raws txoj kab txiav ntawm daim ntawv. Raws li qhov siab ntawm daim ntawv xovxwm nce, qhov ua tau ntawm daim ntawv raug rub tawm ntawm daim ntawv xovxwm yog me me, thiab qhov raug txiav yog siab. Qhov kev hloov ntawm lub siab ntawm cov ntawv xovxwm yuav tsum tau kho raws li hom ntawv yuav tsum tau txiav, txiav qhov siab thiab qhov tob ntawm cov hniav sharpening.
Plaub, hom ntawv. Thaum txiav ntau hom ntawv, lub siab ntawm daim ntawv xovxwm thiab lub kaum ntse ntse ntawm cov hniav yuav tsum tau yoog rau nws. Qhov tseeb presser siab yuav tsum tso cai rau lub cutter txiav ncaj rau hauv pawg ntawm daim ntawv. Nws feem ntau ntseeg tias thaum txiav cov ntawv mos thiab nyias, lub siab ntawm cov ntawv xovxwm yuav tsum siab dua. Yog tias qhov siab me me, daim ntawv nyob rau sab saum toj ntawm cov ntawv pawg yuav khoov thiab deformed, thiab deformation ntawm txheej sab saud ntawm cov ntawv pawg yuav loj. Thaum txiav cov ntawv tawv thiab du, lub siab ntawm daim ntawv xovxwm yuav tsum me dua. Yog hais tias lub siab siab dhau lawm, cov hniav yuav yooj yim deviate rau sab uas tsis tshua muaj siab thaum txiav. Daim ntawv tom qab txiav yog luv luv rau saum thiab ntev rau hauv qab. Thaum txiav cov ntawv nyuaj, kom kov yeej qhov kev txiav tawm, lub kaum sab xis ntawm lub cutter yuav tsum loj dua. Txwv tsis pub, vim lub thinness ntawm sharpening ntug, lub shear kuj ntawm daim ntawv yuav tsis kov yeej, ua rau tsis txaus txiav nyob rau hauv qab ntawm daim ntawv pawg, uas cuam tshuam rau qhov zoo ntawm txiav.
Thib tsib, cov ntsiab lus dej ntawm daim ntawv. Raws li cov ntsiab lus dej hauv daim ntawv nce, cov shear tsis kam txo qis thiab txiav qhov tseeb nce. Nyob rau tib lub sijhawm, thaum cov dej ntsiab lus ntawm daim ntawv loj, kev sib txhuam coefficient yog loj, thiab ib feem ntawm cov ntawv yuav tsum tau txiav yog ib qho nyuaj rau txav los ntawm inclined nto ntawm riam, squeezing cutter riam thiab cuam tshuam rau cov ntaub ntawv. raug txiav. Qhov zoo tshaj noo noo cov ntsiab lus nyob rau hauv daim ntawv yog hais txog 7% mus rau 8%.
6. Lub xeev ntawm daim ntawv txiav. Lub parallelism thiab qhov siab ntawm cov hniav txiav thiab lub worktable, qhov verticality ntawm cov hniav txiav thiab lub worktable, parallelism ntawm qhov chaw ua hauj lwm thiab cov kab txiav ntawm lub pusher, thiab qhov verticality ntawm lub worktable yog qhov tseem ceeb los xyuas kom meej qhov txiav. zoo. Thaum txhim kho thiab tswj cov ntawv txiav, cov khoom no yuav tsum tau kho kom raug kom cov hniav thiab cov hniav yog qhov sib txawv, thiab daim ntawv yuav tsum tau txiav raws li qhov yuav tsum tau ua. Cov yam ntxwv saum toj no uas cuam tshuam rau qhov zoo ntawm kev txiav ib daim ntawv tseem yog qhov tseem ceeb uas cuam tshuam rau qhov zoo ntawm cov phau ntawv thiab lub sijhawm.
Xya, khi txoj kev sib txawv. Qhov sib txawv ntawm qhov tuab ntawm sab xub ntiag ntawm phau ntawv thaiv thiab sab nraub qaum ntawm phau ntawv yog txawv. Rau cov phau ntawv thaiv yuav tsum tau txiav rau peb sab, lub thickness ntawm lub hauv ntej qhib thiab sab nraum qab ntawm phau ntawv yuav tsum yeej ib txwm zoo tib yam. Qhov ntau dua qhov sib txawv ntawm ob, qhov kev txiav raug raug. Qhov txiav qhov siab yuav tsum tau hloov kho raws li daim ntawv zoo, txoj kev khi thiab lub thickness ntawm phau ntawv.
Rau ib phau ntawv sau nrog lub hau, cov kua nplaum txheej hauv qab ntawm phau ntawv yuav tsum tau qhuav thiab ntub. Yog tias lub nraub qaum ntawm phau ntawv tsis qhuav txaus, cov kua nplaum yuav dhau mus thiab ua raws li cov riam sab thaum txiav; yog tias sab nraub qaum ntawm phau ntawv qhuav dhau lawm, cov riam sab yuav nrawm nrawm thaum txiav. Ob qho xwm txheej ua rau txiav nyuaj.
