1.Dab tsi yog cov teeb meem tseem ceeb?
Thaum lub sij hawm stamping, cov hlau substrate (steel lossis aluminium) undergoes yas deformation. Cov txheej txheem organic rau saum npoo yuav tsum muaj peev xwm synchronously thiab ua raws li cov substrate deformation yam tsis muaj cracking lossis detaching. Qhov no yuav tsum tau cov txheej txheem kom muaj kev yooj yim, ductility, thiab adhesion.
2.Dab tsi yog txhais ntawm "them stamping"?
Loj dabtsi yog khoov vojvoog: Lub vojvoog sab hauv (R-lub kaum sab xis) ntawm txhua qhov khoov yuav tsum tsis pub tsawg tshaj 2-3 npaug ntawm daim ntawv tuab. Qhov me me ntawm R-lub kaum sab xis, qhov ntau dua qhov kev ntxhov siab ntawm cov bears.
Tsis tshua muaj qhov tob tob: qhov tob tob tob, nrog cov khoom siv tsawg tsawg uas ncav cuag deformation (piv txwv li, kos qhov tob tsawg dua 10% -15% ntawm cov kab uas hla lossis qhov dav).
Maj mam undulations: Xws li me ntsis tav, pob, louvered flanges, thiab lwm yam, es tsis txhob sib sib zog nqus khob khob- zoo li qhov chaw.
Kev sib sau yooj yim: Xws li cov flanges yooj yim, ntiav cov hluav taws xob txuas hluav taws xob, cov npog zoo nkauj, teeb pom kev zoo, ntsuas vaj huam sib luag, thiab lwm yam.
2.Yuav xaiv cov ntaub ntawv zoo li cas?
Txheej txheej yog qhov tseem ceeb:
Zoo dua, siv cov txheej txheem hloov tau yooj yim: xws li plastisol (PVC) txheej. Cov txheej txheej no tuaj yeem yog 100-200μm tuab lossis tuab dua, ua haujlwm zoo li "daim tawv nqaij", muab cov kev cuam tshuam zoo heev thiab kev tsim, ua rau lawv zoo tagnrho rau qhov chaw ntiav ntiav.
High-cov txheej txheem zoo: Xaiv qhov sib sib zog nqus- kos duab qib polyester (SP), siab - huab cua- polyester resistant (HDP), los yog polyurethane (PU), thiab qhia meej rau tus neeg muag khoom tias nws yuav siv rau "nthuav- kos duab" thaum xaj. Lawv yuav kho cov txheej txheem txheej txheem thiab kho cov txheej txheem los txhim kho qhov yooj.
Zam cov txheej tawv tawv thiab nkig: xws li cov polyester zoo tib yam (PE) lossis dhau - cov txheej ci, uas muaj qhov tsis zoo thiab ua rau tawg.
Kev xaiv substrate:
High- zoo galvanized substrates (xws li DX51D + Z, DX52D + Z, DX53D + Z): Qhov "D" nyob rau hauv qib qhia stamping. Qib xws li DX53D/DX54D (raws li European qauv) los yog CQ, DQ, DDQ (raws li American qauv) muaj substrates nrog zoo heev sib sib zog nqus{10}} kos duab zog.
Primer adhesion: Cov tshuaj hloov pauv txheej (passivation txheej) ntawm lub substrate thiab primer yuav tsum muaj adhesion zoo, uas yog lub hauv paus rau txheej txheej txheej kom tsis txhob poob.
3.Yuav ua li cas los txhim kho pwm thiab cov txheej txheem?
Pwm Tsim:
High Polishing, Zero Defects: Tag nrho cov pwm nto nyob rau hauv kev sib cuag nrog lub txheej (tshwj xeeb tshaj yog lub rounded kaum ntawm lub punch thiab tuag) yuav tsum tau polished heev, tsis muaj khawb los yog burrs, kom txo tau kev sib txhuam thiab puas.
Lub kaum sab xis tsim nyog: Lub kaum sab xis ua haujlwm ntawm cov pwm yuav tsum loj npaum li qhov ua tau, thiab yuav tsum tsis txhob tsawg dua qhov tsawg kawg nkaus khoov vojvoog uas tau tso cai los ntawm cov khoom siv.
Tsim nyog Clearance: Pwm clearance yuav tsum raug tswj kom meej; me me heev clearance yuav ua rau shearing thiab ntau compression ntawm txheej.
Stamping txheej txheem:
Siv Lubricant Tshwj Xeeb: Tsis muaj zog, tsis yog - pa phem stamping roj los yog lubricant yuav tsum tau siv. Lubrication txo kev sib txhuam thiab txo qhov kev pheej hmoo ntawm txheej khawb los yog tev. Nws yuav tsum yooj yim los ntxuav tom qab stamping.
Tswj Stamping Ceev: Siv qhov tsawg thiab ruaj khov stamping ceev kom tsis txhob muaj kev ntxhov siab ntau dhau los ntawm kev kub siab - ceev.
Ua kom huv: xyuas kom meej tias cov pwm thiab cov ntawv hlau tsis muaj qhov nyuaj los tiv thaiv kev sib tsoo.
4.Dab tsi yog qhov tsim nyog preprocessing thiab postprocessing cov kauj ruam?
Cov khoom siv: Ua ntej stamping, cov khoom yuav tsum nyob rau hauv zoo, tsis muaj creases thiab khawb, thiab cov txheej txheem yuav tsum tau nqa tawm nyob rau hauv ib tug haum kub (chav tsev kub).
Kev Tiv Thaiv Ntug: Tom qab stamping, cov npoo ntawm cov khoom yuav nthuav tawm cov hlau substrate, uas yog qhov tsis muaj zog rau kev tiv thaiv corrosion. Rau sab nraum zoov lossis siab - qhov yuav tsum tau muaj, cov npoo txiav yuav tsum raug kaw (piv txwv li, los ntawm kev siv cov tshuaj tiv thaiv- xeb, tshuaj pleev xim rau, lossis txhim kho cov hniav zoo nkauj).
5.Dab tsi yuav tsum tau xeem?
Cupping Test: Qhov kev txwv ntawm cov khoom siv yog sim siv lub tshuab Erichsen cupping tester. Saib xyuas seb cov txheej txheej puas tawg thaum nws protrudes mus rau qhov siab teev.
Bending Test: Cov khoom yog khoov 180 degrees mus rau qhov tsawg kawg nkaus khoov vojvoog ntawm cov khoom tiag. Sab nrauv ntawm txheej yog kuaj xyuas kom tawg.
Kev Xeem Adhesion: Ib qho kev sib tw - txiav adhesion yog ua rau ntawm qhov chaw stamped kom paub tseeb tias cov txheej tsis tev tawm vim deformation.
