1.Yuav ua li cas peb thiaj paub tseeb tias cov khoom siv ntawm cov khoom ua tau raws li cov qauv?
Elongation (A80, A50): Qhov no yog qhov taw qhia tseem ceeb ntawm cov khoom siv yas. Cov neeg muag khoom yuav tsum muab cov txiaj ntsig elongation tau lees paub uas ua tau raws li lossis tshaj qhov yuav tsum tau ua. Rau txoj kev sib sau los yog ze rau -flanging, siab dua- qib sib sib zog nqus- kos duab hlau (xws li DC04, DC05, DC06) yuav tsum xaiv.
Ua Haujlwm Hardening Index (n-tus nqi): Qhov ntau dua qhov n- tus nqi, qhov muaj zog ntawm cov khoom muaj peev xwm ua kom elongate uniformly thaum lub sij hawm deformation, thiab qhov tsawg dua nws yog nyob rau hauv lub caj dab thiab tawg. Sib sib zog nqus- kos duab hlau muaj ntau dua n- tus nqi.
Plastic Strain Ratio (r-tus nqi): Qhov siab r- tus nqi qhia tau hais tias cov khoom siv tsawg dua tuaj yeem ua rau nyias nyias nyob rau hauv cov kev taw qhia tuab thiab ntws yooj yim hauv daim ntawv dav hlau, uas yog qhov zoo rau flanging. Ib qho r-tus nqi> 1.5 feem ntau yuav tsum tau.
2.Yuav kuaj xyuas qhov zoo ntawm cov khoom ntug?
Slitting Burrs: Burrs generated thaum lub sij hawm slitting txheej txheem yog cov ntsiab lus kev ntxhov siab thiab ib qho ntawm cov laj thawj tseem ceeb ntawm ntug kev tawg. Qhov siab burr tom qab slitting yuav tsum tau tswj kom muaj ntau yam me me (piv txwv li, Tsawg dua lossis sib npaug li 0.02mm), lossis txheej txheem deburring yuav tsum tau npaj.
Ntug Cracks/Hardened Layer: Tshawb xyuas cov ntug dov rau micro- tawg lossis shear hardened txheej uas tsis pom ntawm qhov muag liab qab. Yog tias tsim nyog, lub teeb ntug dov lossis tua blasting tuaj yeem siv los tshem tawm cov ntug tawv txheej thiab micro- tawg.
3.Kuv tuaj yeem lees paub qhov xwm txheej ntawm cov ntaub ntawv li cas?
Tsis txhob siv cov ntaub ntawv nyuaj dhau: xyuas kom cov khoom tau dhau los ua kom txaus thiab nyob rau hauv lub xeev mos (xws li DC01, DC04). Cov ntaub ntawv nyuaj dhau (piv txwv li, tawv lossis ib nrab- cov xeev nyuaj) muaj cov yas tsis zoo thiab ua rau tawg yooj yim heev.
Ua tib zoo saib xyuas cov txheej txheem txheej txheej / roj zaj duab xis: Cov adhesion ntawm zinc txheej ntawm cov ntawv galvanized (GI / GA), cov txheej txheem txheej txheej ntawm cov ntawv coated, thiab qhov sib xws ntawm cov tshuaj tiv thaiv - xeb roj tag nrho cuam tshuam rau txoj kev tsim.
4.Yuav ua li cas los txhim kho pwm tsim?
Nce lub vojvoog dabtsi yog khoov (R lub kaum sab xis): Qhov no yog txoj hauv kev ncaj qha thiab zoo tshaj plaws. Sab hauv R lub kaum sab xis ntawm lub npoo npoo yuav tsum yog tsawg kawg yog 1 npaug ntawm cov khoom tuab (t), nrog 1.5t-2t pom zoo. Qhov me me R lub kaum sab xis, qhov loj dua hauv zos thiab qhov yooj yim dua yog tawg.
Teeb pom kev tuag kom raug: Qhov kev tshem tawm ntawm qhov xuas nrig ntaus lossis khoov tuag yuav tsum yog nruab nrab. Yog tias qhov kev tshem tawm tsawg dhau, cov khoom siv yuav raug nyem thiab khawb, ua rau kev puas tsuaj ntawm ntug; Yog hais tias qhov clearance loj dhau lawm, yuav muaj burrs loj thiab tsis ruaj tsis khov. Qhov kev tshem tawm ntawm ib sab yog feem ntau 8% -12% ntawm cov khoom tuab.
Txhim kho qhov tuag nto tiav: Qhov chaw ua hauj lwm ntawm qhov tuag (tshwj xeeb tshaj yog qhov sib npaug ntawm cov kab noj hniav tuag) yuav tsum tau polished heev kom txo tau cov kev sib txhuam ntawm cov khoom ntws.
Xyuas kom qhov sib dhos tuag thiab qhov sib npaug: Tiv thaiv cov khoom tsis sib xws los ntawm kev tawm ntawm - chaw thau khoom.
5.Dab tsi yog qee yam uas yuav tsum nco ntsoov txog cov txheej txheem thiab kev ua haujlwm?
Siv cov roj nplaum zoo - zoo:
Siv cov roj nplua nyeem tshwj xeeb rau qhov chaw crimped zoo txo kev sib txhuam ntawm cov khoom siv thiab cov tuag, txo qis kev sib sau, thiab txhawb nqa cov khoom zoo sib xws. Lubrication yog ib qho tseem ceeb rau kev nyuaj - rau - cov ntaub ntawv xws li stainless hlau.
Tswj kev sib sau ceev:
Tsim nyog txo cov stamping los yog dabtsi yog khoov ceev kom tso cai rau cov ntaub ntawv ntau txaus lub sij hawm txhim kho formability thiab txo cov kev ntxhov siab nyob rau hauv lub zos ntau dhau los ntawm inertia.
Kho crimp kev taw qhia:
Teem rau ib lub kaum sab xis ntawm qhov kev taw qhia crimp thiab dov kev taw qhia (zoo tagnrho 45℃lossis perpendicular). Txij li thaum lub elongation ntawm cov khoom raws li dov kev taw qhia feem ntau yog ntau dua li qhov perpendicular rau nws, hloov cov kev taw qhia siv cov khoom anisotropy.
Tswj qhov chaw ua haujlwm:
Khaws cov khoom kom huv si thiab tiv thaiv cov plua plav thiab cov khoom los ntawm kev nias rau hauv, uas tuaj yeem ua rau muaj kev ntxhov siab.
