Kuv tau nyob rau hauv kev sib cuag nrog ntau offset printers. Thaum lub tshuab luam ntawv tau hloov lawm thaum hloov daim ntawv luam tawm, lub phom rau ntawm daim pam pob cyuam tsuas yog tshem tawm, thiab sab hauv ntawm lub stencil yog ntxiv rau lub phom lub plhaub txhais tau hais tias nws yog qhov yooj yim. Qee lub sij hawm nws tuaj yeem ua haujlwm, tabsis cov no tuaj yeem ua haujlwm yog tias daim ntawv muaj ntau yam kev hloov (qhov tseeb, qhov siab ntawm lub phom lub tog raj kheej thiab dej rau cov menyuam thiab cov quav caws quav muaj zog, uas yuav cuam tshuam cov qauv ntawm cov ntawv luam tawm Qhov cuam tshuam ntawm luv version ntawm lub cus ciav yuav tsis raug). Yog hais tias lub thickness ntawm daim ntawv no nws txawv heev, nws tsis yog kom tsuas yog txo qhov hauv ob sab phlu.
Qhov tseeb, txhua qhov offset xovxwm muaj qhov theoretical siab. Peb yuav tsum tau ua ntau yam kev kho raws li qhov kev ua theoretical (kho qhov sib txawv, hloov lub meem) kom ua tiav qhov kev luam siab zoo uas ua tau raws li cov kev cai luam tawm. Tsab ntawv no yuav ua kom paub qhov theoretical pressure calculation los ntawm kev noj cov tsis yooj yim ntawm ib yam qauv ua piv txwv. Cov mis, qhov ntxhib xam mis ntawm tuab daim ntawv, yog qhov muab xam cov ntawv ntawm cov ntawv tuab thiab cov txheej txheem cov ntawv xeem, yog li ntawd cov phooj ywg tuaj yeem siv tau rau hauv kev xyaum:
Piv txwv:
Cov kev tsis tau ntawm tus qauv yog raws li nram no:
Clearance:
Nruab nrab ntawm lub phom khawm thiab pam lub khawm kheej 3.70 hli
Nruab nrab ntawm pam lub tog raj kheej thiab lub tswv yim kheej kheej 3.05 hli
Meem:
Plate kheej kheej kheej (nrog rau phaj, liner) 0.65 hli
Roj Hmab Rab Riam (nrog rau roj hmab, hauv ob sab phlu ntoo, daim ntawv thim ntawv) 3.25 hli
Nrog rau cov kev ua tsis tau zoo no, peb siv tau cov formula yooj yim los laij cov laj thawj siab:
Cov qauv ntawm kev ntsuas qhov theoretical pressure:
Lub qhov quav ntawm lub qhov quav - sib kis = siab
Muab xam los ntawm:
Ua ntej pib lub siab ntawm lub tswv yim kheej kheej thiab pam lub tog raj kheej
Hloov cov ntaub ntawv: 3.25-3.05 = 0.20 (hli)
Thib ob xam lub siab ntawm lub phom lub tog raj kheej thiab pam lub tog raj kheej
Hloov cov ntaub ntawv: 3.25 + 0.65-3.70 = 0.20 (hli)
Peb lub thawv muaj qhov siab ntawm 0.20 mm nrog txhua lwm yam tsis muaj luam ntawv. Txawm li cas los xij, hauv ib txwm luam ntawv, ib txwm luam ntawv (daim ntawv luam tawm) yuav tsum muab ntxiv nrog lub thickness ntawm 0.10 hli ntawm lub tswv yim kheej kheej thiab pam lub tog raj kheej, thiab luam ntawv siab ntawm lub tswv yim kheej kheej thiab pam lub plhaub yog 0.30. Mm.
Xaus: Lub siab ntawm lub tshuab luam tawm ntawm cov qauv no yuav tsum muab ceev cia rau hauv qhov kev khwv tshaj qhov saum toj no, uas yog, 0.20mm nruab nrab ntawm lub phom lub tog raj kheej thiab pam lub tog raj kheej, thiab 0.30mm ntawm pam lub tog raj kheej thiab lub tswv yim kheej.
Yog hais tias cov ntawv tuab ntawm daim ntawv luam tawm tsawg dua 0,10mm, peb tuaj yeem tsis muaj kev hloov thiab sib rho. Thaum luam ntawv nyias nyias lawm, lub tshuab luam ntawv siab yuav tsum me dua, yog li peb tuaj yeem lav cov ntawv luam ntawm cov ntawv nyias tsis muaj kev hloov kho, vim peb qhov siab tshaj plaws yuav tsum tau nyob ntawm 0.20mm.
Yog hais tias cov ntawv tuab ntawm daim ntawv luam peb siab tshaj 0.10 hli thiab tsawg dua 0.20 hli, peb tuaj yeem kho nws raws li cov qauv nram qab no:
Thickness ntawm tuab daim ntawv (tsuas yog kho qhov sib txawv, tsis yog khoov) mis formula:
X = 3.05 + daim ntawv thickness-0.10
Qhov twg: X yog qhov sib txawv ntawm pam lub tog raj kheej thiab lub tswv yim kheej kheej uas yuav tsum tau kho thaum sau ntawv tuab
Yog hais tias cov ntawv tuab ntawm daim ntawv luam ntau tshaj 0.20mm, peb tuaj yeem kho nws raws li cov qauv nram qab no:
Qhov tseeb ntawm daim ntawv tuab (ob txoj kev hloov ntawm qhov sib txawv, tab sis kuj txo qhov hauv ob sab phlu) mis formula:
X = 3.05 + daim ntawv thickness-0.10-B
B = (daim ntawv thickness-0.10) / 10
Qhov twg: X Qhov nruab nrab ntawm pam lub tog raj kheej thiab lub tswv yim kheej kheej uas yuav tsum tau kho thaum sau ntawv tuab tuab.
B Tus nqi ntawm daim ntawv los ntawm pam lub tog raj kheej
Lub hauv paus xeem rau cov ntawv khaws:
Peb tau ncaav cov neeg xyaum kawm los ua cov kev sim. Tom qab kho qhov sib txawv nruab nrab ntawm lub pog thiab lub khawm kheej, qhov sib txawv nruab nrab ntawm cov phom khawm thiab daim poom plhaw yog ntsuas thiab kaw tseg:
Cov ntaub ntawv 1
Qhov sib txawv ntawm lub thawv pam thiab lub tswv yim lub tswv yim: 3.05mm - 3.45mm + 0.40mm
Qhov sib txawv ntawm cov phom khawm thiab pam poom: 3.70mm - 3.66mm - 0.04mm
Cov ntaub ntawv 2
Qhov sib txawv ntawm lub thawv pam thiab lub tswv yim khawm: 3.05mm - 3.25mm + 0.20mm
Qhov sib txawv ntawm cov phom khawm thiab pam lub tog raj kheej: 3.70mm - 3.68mm - 0.02mm
Kuaj Cov Lus Sib Cog:
Qhov sib txawv ntawm lub pog thiab lub khawm lub tswv yim thiab qhov txo qhov sib txawv ntawm lub phom khawm thiab pam lub tog raj kheej yog raws nraim 10: 1, uas yog lub hauv paus ntawm daim nqi ntawv B.
Qhov thib peb muab formula tsuas tuaj yeem ntsib cov tshuab luam ntawv uas tsis muaj qhov muag, thiab lub tshuab luam ntawv tsis zoo yuav tsum tsis txhob ua qhov sib txawv nruab nrab ntawm lub luam tawm khawm thiab pam lub tog raj kheej tom qab kho qhov nruab nrab ntawm lub thawv pam thiab lub tswv yim kheej. Kev kho, qhov tshuab luam ntawv tshuab luam ntawv yuav suav thiab kho nrog lub mis thib ob thaum lub tshuab luam ntawv loj dua 0.10 hli.
