1.Puas txias- dov coil warp tom qab txiav?
Tsis muaj kev sib koom ua ke hauv teb chaws tus qauv: Tam sim no, tsis muaj lub teb chaws tus qauv tsim nyog rau "warpage tom qab slitting" zoo li muaj rau txias -rolled raw steel sheets. Nws yog kev tshaj tawm - cov yam ntxwv ua haujlwm thiab cuam tshuam los ntawm ntau qhov sib txawv.
Qhov teeb meem yog dav: Ib qho kev sib tw ntawm warpage (tshwj xeeb tshaj yog transverse warpage, piv txwv li, "sickle khoov") tom qab slitting yog ib qho tshwm sim, hauv paus hauv kev tso tawm thiab rov faib cov kev ntxhov siab nyob hauv cov khoom.
Txawm hais tias nws ua tau raws li tus qauv yog nyob ntawm "cov qauv ntawm cov neeg siv khoom": Qhov kev ntsuas qhov kawg yog koj cov khoom yuav tsum tau ua thiab cov txheej txheem ua tom ntej. Piv txwv li, qhov yuav tsum tau ua rau precision pwm pads thiab siab -kawg of elevator panels yog siab dua li cov khoom txee lossis cov khoom siv zoo tib yam.
2.Dab tsi yog qhov ua rau warping?
Intrinsic Material Factors (Master Coil Condition):
Residual Stress: Thaum lub sij hawm txias dov thiab annealing, txawm tias daim ntawv qub ncaj, micro- kev ntxhov siab tseem "xauv" hauv cov khoom. Slitting zoo li txiav lub ncuav mog qab zib; txiav tawm qee qhov kev txwv tso tawm kev ntxhov siab raws li kev txiav, ua rau lub sawb khoov rau sab nrog qis dua kev ntxhov siab.
Daim Ntawv Tsis Zoo: Yog tias tus tswv coil nws tus kheej muaj waviness (ntug waviness, nruab nrab waviness), qhov tsis sib xws tom qab slitting yuav txhais ua ntau tshaj tawm warping.
Inhomogeneous Properties: Qhov sib txawv me ntsis ntawm hardness thiab grain qauv thoob plaws cov khoom cross-section ua rau inconsistent shrinkage ntawm ob sab tom qab slitting.
Slitting txheej txheem Factors (Key Controllable Points):
Tool Condition thiab Configuration:
Tool Gap: Qhov sib txawv ntawm sab sauv thiab sab hauv cov hniav yog qhov tseem ceeb. Qhov sib txawv loj heev ua rau cov khoom raug "rho" es tsis yog sheared, ua rau loj burrs thiab tsis sib xws deformation; Qhov sib txawv me me dhau los ua rau muaj kev sib zog hnyav, ob qho tib si exacerbating kev ntxhov siab tso tawm thiab warping.
Lub Taub Hau Taub Hau Taub Hau: Loj radial runout lossis kawg lub ntsej muag ntawm cov cuab yeej, los yog misalignment thaum lub sij hawm installation, yuav ua rau instability nyob rau hauv cov txheej txheem shearing, ua rau lub sij hawm warping.
Kev tswj nruj: Lub nro siv los ntawm lub tshuab slitting thaum winding yuav tsum tsis sib xws thiab tsim nyog. Yog tias qhov nro qis dhau, lub strip yuav xoob thiab qhov kev ntxhov siab yuav yooj yim tso tawm; Yog tias qhov nro siab dhau lawm, nws yuav "txoj kev ncaj" tab sis kev ntxhov siab ntau ntxiv yuav ua rau sab hauv tom qab winding, thiab nws tseem yuav rov ua dua thaum unwinding.
3.Yuav ua li cas txiav txim siab thiab ntsuas seb "tus qauv" puas tau ua tiav?
Tsim Cov Qauv Kev Lag Luam lossis Cov Ntawv Pom Zoo Kev Lag Luam: Koj (tus neeg yuav khoom) yuav tsum qhia meej meej txog cov txheej txheem kev xeem warpage thiab cov qauv siv tau nrog tus neeg xa khoom hauv daim ntawv cog lus lossis kev pom zoo. Piv txwv li:
Txoj Kev Ntsuas: Tso ib txoj hlua ntawm qhov ntev (piv txwv li, 1 meter lossis 2 meters) tiaj tus ntawm lub platform thiab ntsuas qhov siab tshaj plaws (H) ntawm nws qhov siab tshaj plaws thiab lub platform siv lub ntsuas ntsuas ntsuas, lossis ntsuas nws qhov siab chord.
Cov qauv siv tau: Qhia qhov siab tshaj plaws tso cai warpage qhov siab ntawm ib lub 'meter' ntev (piv txwv li, Tsawg dua lossis sib npaug rau 2mm / m, Tsawg dua lossis sib npaug li 1mm / m, thiab lwm yam). Rau siab - cov khoom yuav tsum tau muaj, cov qauv yuav nruj heev.
Tsim cov qauv raws li cov ntawv thov hauv qab:
Siab -Precision Stamping/Laser Txiav: Cov kev xav tau siab heev; warpage yuav tsum tsis tshua muaj me me (piv txwv li,<1mm/m), otherwise it will affect feeding accuracy, positioning, and finished product flatness.
Ordinary Bending/Structural Cheebtsam: qis dua; me ntsis warpage tuaj yeem kho tau los ntawm kev khoov tshuab khoov, thiab cov qauv tuaj yeem kho tau.
Kev txhim kho ncaj qha (piv txwv li, Pem Teb Slabs): Cov kev xav tau nruab nrab; xyuas kom haum zoo thaum lub sij hawm installation yam tsis muaj teeb meem waviness.
4.Yuav ua li cas txhim kho thiab tswj sawb warping?
Xaiv cov qib siab- zoo master coils: Pib los ntawm qhov chaw, xaiv txias-rolled coils nrog cov duab zoo thiab kev ua haujlwm zoo.
Optimize cov txheej txheem slitting:
Kho cov hniav sib txawv: Precisely kho qhov sib txawv ntawm lub sab sauv thiab sab hniav raws li cov khoom thickness thiab hardness (feem ntau 8% -12% ntawm cov khoom thickness).
Xyuas kom cov hniav sharpness thiab precision: ntswj cov hniav thiab xyuas cov hniav tsis tu ncua.
Tswj nro: Teem kom tsim nyog winding thiab unwinding nro nkhaus thiab tswj stability.
Ua kom lub tsev ncaj nraim: Qhov no yog kauj ruam tseem ceeb tshaj plaws. Straightening rollers plastically deform lub sawb, tshem tawm kev ntxhov siab tsis sib xws.
Txhim kho ntim thiab khaws cia: Tom qab slitting, lub sawb yuav tsum nruj nreem kaw thiab khaws cia ntsug kom tsis txhob muaj deformation ntxiv vim qhov chaw tsis raug.
5.Koj muaj lus qhia dab tsi?
Txhais koj cov kev xav tau: Ua ntej, qhia meej cov kev cai tshwj xeeb ntawm koj cov txheej txheem ua haujlwm tom ntej.
Ntawm -kev tshuaj xyuas thiab kev sib txuas lus ntawm qhov chaw: Sib txuas lus nrog cov neeg muab khoom slitting kom nkag siab txog lawv cov cuab yeej muaj peev xwm (txawm lawv muaj lub tshuab ncaj), cov txheej txheem tswj, thiab cov qauv tswj kom zoo.
Kos npe rau daim ntawv cog lus ua haujlwm: xyuas kom meej tias txoj kev ntsuas kev ua tsov rog, kev txwv tsis pub siv, thiab kev tshuaj xyuas cov khoom tau teev meej meej hauv kev sau ntawv hauv daim ntawv cog lus.
Cov me me -batch sim ntau lawm: Ua ntej koom tes nrog tus neeg muag khoom tshiab lossis siv cov ntaub ntawv tshiab, ua ib qho me me -batch sim slitting los xyuas seb cov txiaj ntsig tiag tiag puas tau raws li koj xav tau.
