1.Dab tsi yog qhov phom sij ntawm burrs ntawm ntug txias -rolled coils? Vim li cas lawv thiaj yuav tsum tau tswj xyuas nruj?
Kev pheej hmoo ntawm kev tawg ntawm cov hlua khi thaum dov: Hauv qhov txias tas li dov, burrs ntawm cov npoo npoo tuaj yeem yooj yim khawb lub yob nto, txawm tias ua rau strip breakage thiab ntau lawm stoppage.
Deg indentation defects: Burrs uas ntog tawm mus rau ntawm lub strip nto tuaj yeem nias rau hauv cov yob, ua rau lub sij hawm indentations, ua rau cov khoom downgrading los yog scrapping.
Zinc plating teeb meem zoo: Rau cov khoom uas yuav tsum tau galvanizing, burr cheeb tsam feem ntau muaj tsis sib xws los yog tsis tiav plating, cuam tshuam rau corrosion kuj.
Kev ua haujlwm tom ntej: Thaum lub sij hawm stamping, burrs tuaj yeem khawb qhov tuag, thiab cov burrs lawv tus kheej tuaj yeem dhau los ua cov ntsiab lus kev ntxhov siab, ua rau cov kab nrib pleb. Yog li ntawd, siab -txheej txheem txias- dov coils feem ntau yuav tsum tau burr qhov siab tswj nyob rau hauv 0.02mm (20μm), thiab precision daim ntawv thov txawm xav tau tsawg dua los yog sib npaug rau 15μm.
2.Dab tsi yog qhov laj thawj tseem ceeb ntawm ntug burrs?
Cov txheej txheem disc shear tsis tsim nyog: Qhov no yog qhov tseem ceeb tshaj plaws. Kev teeb tsa cov hniav tsis raug cai thiab sib tshooj ncaj qha ua rau burrs. Cov kev tshawb fawb pom tau hais tias qhov sib txawv ntawm cov hniav sib txawv muaj qhov cuam tshuam loj dua ntawm ntug zoo dua li qhov sib tshooj. Yog tias qhov sib txawv loj heev, cov khoom yuav raug rub tawm ntau dua li sheared, ua rau cov burrs loj; Yog hais tias qhov sib txawv me me dhau lawm, shear hniav hnav yuav nrawm, kuj yooj yim ua rau lwm yam shearing.
Cov hniav tsis zoo: Hnav thiab dulling ntawm cov hniav, chipping, los yog axial vibration ntawm lub shear hniav thaum shearing vim xoob hydraulic txiv ntseej yuav ua rau tsis sib xws shearing nto thiab burrs.
Cov khoom tsis zoo hauv cov ntaub ntawv kub-rolled raw: Cov khoom tsis zoo xws li ntug waviness, camber, thiab cov kab nrib pleb hauv cov khoom tuaj yuav ua rau lub zog tsis sib xws thaum shearing, cuam tshuam cov hniav shear, ua rau "hnav slippage" los yog tsis tiav shearing nyob rau hauv tej qhov chaw, yog li ua burrs.
Kev ntsuas tsis raug: Yog tias txoj kev sib txawv ntawm cov hniav sib txawv yog qhov yooj yim heev (xws li tso siab rau ib lossis ob qhov kev ntsuas nrog lub ntsuas ntsuas), nws yuav ua tsis tau raws li qhov sib txawv tiag tiag, kuj ua rau cov txheej txheem tsis sib txawv ntawm qhov zoo tshaj plaws.
3.Yuav ua li cas burrs tuaj yeem tswj tau los ntawm kev ua kom zoo dua cov txheej txheem ntawm cov disc shear?
Shear blade clearance: Qhov kev tshem tawm feem ntau yog siv li 8% mus rau 12% ntawm cov sawb tuab, tab sis cov nyiaj tshwj xeeb yuav tsum tau suav nrog cov qauv raws li cov khoom siv zog thiab tuab. Rau ultra- cov pa roj carbon tsawg xws li IF steel, Shougang cov kev tshawb fawb tau muab cov qauv kev suav tshwj xeeb rau cov khoom siv txuas ntxiv thiab cov khoom siv galvanized, uas txo qis qhov siab ntawm qhov siab tom qab thov. Ib qho kev tshem tawm loj heev ua rau muaj kev faib ua feem ntawm thaj tsam puas tsuaj, ua rau ntau dua burrs; ib qho kev tshem tawm me me dhau mus ua rau thaj chaw shear loj heev, ua rau cov ntoo hla zoo -sectional zoo tab sis ceev shear hniav hnav.
Shear blade overlap: Lub overlap kuj xav tau kev tswj kom meej. Kev sib tshooj me me ua rau tsis tiav shearing; Kev sib tshooj ntau dhau exacerbates shear hniav hnav thiab tsim extruded burrs. Nws yog feem ntau teem nruab nrab ntawm -3mm thiab +3mm (tsis zoo qhov tseem ceeb qhia tau hais tias ib tug loj clearance) raws li cov strip thickness.
Dynamic adjustment: Kev tswj niaj hnub yuav tsum tau ua kom zoo zoo -tuning raws li qhov tseeb cov duab thiab lub zog hloov pauv ntawm cov khoom tuaj, tsis yog siv cov kev txwv tsis tu ncua.
4.Txawm li cas los xij, lwm txoj kev pabcuam twg tuaj yeem tshem tawm lossis txo cov burrs?
Deburring Rolls (Extrusion Rolls): Ib los yog ntau khub ntawm deburring rollers raug ntsia tom qab lub disc shear. Los ntawm nias rau ntawm ntug ntawm lub strip, burrs yog flattened los yog tshem tawm los ntawm extrusion.
Txheej Optimization: Siv laser cladding txheej es tsis txhob tsoos chrome plating ho txhim kho qhov hnav tsis kam ntawm cov menyuam nto thiab txuas nws lub neej kev pab cuam.
Roll Shape Optimization: Optimizing cov tsoos tiaj tus menyuam rau hauv cov menyuam nkhaus tsis tsuas yog txhim kho cov nyhuv deburring tab sis kuj zam qhov "ci ntug" qhov tsis xws luag los ntawm extrusion ntau dhau.
Ntug Sib Tsoo Tshuab: Rau siab- cov kev xav tau zoo (xws li cov tsheb loj) lossis cov khoom tuab, cov log sib tsoo tuaj yeem siv los zom cov txheej txheem ntawm ntug ntug, tshem tawm cov burrs thiab micro- tawg. Advanced ntug sib tsoo cov cuab yeej tuaj yeem taug qab cov sawb nrawm thiab txoj haujlwm ntawm lub sijhawm, tuaj yeem kho qhov sib tsoo tus nqi, thiab them nyiaj rau cov teebmeem ntawm cov menyuam hnav thiab sawb ntug waviness, ua tiav qhov siab precision sib tsoo.
5.Yuav tshuaj xyuas thiab tswj qhov zoo ntawm burrs ntawm qhov chaw tsim khoom?
Kev soj ntsuam online: Siv cov laser scanners lossis siab - lub koob yees duab ceev, cov npoo ntawm cov sawb sheared raug tshuaj xyuas hauv online los saib xyuas qhov siab burr thiab morphology hauv lub sijhawm. Lub tswb yog tam sim ntawd tshwm sim los yog shearing tsis tau hloov kho yog tias pom muaj ntau tshaj.
Offline Sampling Inspection: Lub tshuab yog ncua sij hawm los ntsuas qhov kev tshem tawm cov hniav siv cov ntsuas ntsuas lossis ntsuas ntsuas, thiab ntsuas qhov siab yog ntsuas los ntawm roughness tester lossis 3D profileometer. Piv txwv li, burr morphology raug soj ntsuam siv lub tshuab ntsuas digital nrog 2000x magnification, thiab burr qhov siab yog suav nrog siv lub laser scanner nrog kev daws teeb meem ntawm 0.01μm.
Standardization: Cov tuam txhab lag luam yuav tsum tsim cov txheej txheem tshuaj xyuas nruj, xws li qhia tias tus nqi ntawm cov burrs ntawm ntug txiav yog tswj tsis pub dhau 0.02 hli, thiab tsis tu ncua xyuas qhov hnav ntawm cov deburring rollers kom ntseeg tau tias lawv ua haujlwm zoo.
Cov ntaub ntawv taug qab: Qhov pib thiab xaus txoj haujlwm ntawm txhua lub kauj hlau raug kaw nrog rau cov txiaj ntsig kev tshuaj xyuas burr. Cov cheeb tsam uas muaj kev hloov pauv loj ntawm qhov pib thiab qhov kawg, thiab nquag ua rau cov burr tiam, tau txais kev saib xyuas tshwj xeeb lossis tsim nyog tshem tawm hauv cov txheej txheem tom ntej.
