Tswj Txoj Cai Thiab Daim Ntawv Thov Ntawm Sab Trimming Disc Shear hauv Pickling Kab Ua Ib feem ntawm Coil Slitting Tshuab

Lub disc shear yog ib qho tseem ceeb ntawm cov cuab yeej txiav hauv cov phaj thiab sawb ntau lawm. Qhov no shear nta ob lub disc-zoo li tus hniav, uas yog siv rau longitudinally trimming cov npoo ntawm steel daim hlau thiab strips, los yog rau slitting rau hauv nqaim strips, zoo li ib tug coil slitting tshuab. Qhov no shear yog dav siv rau longitudinal shearing ntawm steel daim hlau thiab nyias strips nrog ib tug tuab ntawm tsawg tshaj li 20 mus rau 30 hli. Vim hais tias cov hniav yog rotating discs, nws muaj peev xwm tsis tu ncua shear txav steel daim hlau los yog strips nyob rau hauv lub longitudinal kev taw qhia. Ib txoj kab txuas txuas ntxiv nyob rau hauv qee cov nroj tsuag steel tau muab tso rau hauv kev tsim khoom thaum Lub Rau Hli 2012, siv lub zog tsis sib xws-shear disc shear. Daim ntawv no qhia txog cov qauv tsim, txheej txheem, thiab kev tswj cov qauv thiab cov yam ntxwv ntawm cov disc shear rau siv.

Lub cev tseem ceeb ntawm kev sib hloov shear tsis muaj lub tshuab tsav sab hauv; Hloov chaw, kev sib hloov ntawm cov hniav yog tsav los ntawm kev txav steel sawb nws tus kheej, uas yog nyob rau hauv nruj, yog li ua tiav qhov "rub-shearing" nkaus. Txhawm rau kom ntseeg tau tias lub cev tseem ceeb ntawm cov phaj hlau tseem nyob rau theem thaum nws tawm ntawm qhov kev sib tsoo-thaum lub ntug ntawm cov hlais raug tso cai rau curl maj mam- txoj kab uas hla ntawm cov hniav sab saud yog tsim los kom me me dua li ntawm cov hniav qis.

 

Concurrently, qhov tsim no tiv thaiv cov edged strips los ntawm curling ntau dhau. Txhawm rau tiv thaiv cov phaj hlau los ntawm kev sib tsoo thaum nws nkag mus rau hauv lub tshuab hluav taws xob, lub siab chais raug ntsia tam sim ntawd ntawm cov hniav. Tsis tas li ntawd, txhawm rau txo qis kev sib txhuam ntawm cov hlau phaj thiab txiav cov npoo ntawm cov hniav, txhua khub ntawm cov hniav yog teem rau ntawm lub kaum sab xis me ntsis rau qhov nruab nrab ntawm cov hlau sawb. Lub hauv paus txheej txheem ntawm chav tsev muaj xws li ib tug taag kev them nyiaj yug ncej, ib tug hniav sib txawv hloov mechanism, thiab ib tug hniav hloov cuab yeej.

Main Performance Parameters ntawm Rotary Shear

Lub rotary shear yog positioned downstream ntawm crescent shear; nws siv cov qauv uas tsis yog -tsav rotary thiab yog siv los txiav cov npoo ntawm cov hlua hlau mus rau qhov dav dav. Ob txheej ntawm cutter hau yog mounted rau ntawm shearing thav duab nyob rau ntawm ob sab ntawm txoj kab ua. Cov shearing thav duab no tuaj yeem tig 180 degrees ntawm lub khib- thiab - pinion mechanism uas tau tsav los ntawm lub tog raj kheej hydraulic. Thaum lub thav duab shearing tau tig mus rau hauv txoj hauj lwm, lub tshuab xauv - ua los ntawm lub tog raj kheej hydraulic - koom ua ke kom ruaj ntseg rau hauv qhov chaw. Thaum ib txheej ntawm lub taub hau txiav yog nquag ua haujlwm shearing, lwm lub teeb tseem muaj rau kev saib xyuas, hloov, lossis hloov kho. Kev hloov dav ntawm cov thav duab shearing yog ua tiav los ntawm kev tsav lub pob ntsia hlau los ntawm lub cev muaj zog, ua rau cov thav duab xaub raws cov lus qhia mounted ntawm lub hauv paus. Thaum qhov xav tau qhov dav mus txog, cov thav ntawv raug kaw rau hauv txoj haujlwm siv threaded hydraulic kheej kheej.

Ib khub ntawm pinch rollers thiab kev txhawb nqa rollers yog nyob rau ntawm lub taub hau cutter inlet. Lub pinch roller sib dhos yog tsav los ntawm hydraulic thooj voos kheej kheej thiab ua haujlwm los tiv thaiv cov hlua khi thaum txhawb nqa lub sawb, yog li ua kom cov shear zoo. Cov khoom seem tsim los ntawm kev sib hloov shear yog qhia ntawm chute mus rau hauv ib qho khoom siv chopper rau ntug chopping. Tom qab cov txheej txheem chopping, cov seem yog xa los ntawm ib lub chute rau hauv cov khoom seem thauj mus los.

Lub hauv paus automation system rau MaSteel pickling kab muaj cov khoom xws li PLCs (Programmable Logic Controllers), HMI system, Industrial Ethernet network, fieldbuses, tej thaj chaw deb I/O chaw nres tsheb (ET200), thiab cov cuab yeej programming, raws li qhia hauv daim duab 2. Rau qhov tshwj xeeb chav tsev no, Siemens SIMATIC tswj tau xaiv.}4{0{0} Tag nrho chav tsev yog nruab nrog peb PLCs, txhua tus siv CPU416-2 module. Lub kaw lus HMI interface yog siv los ntawm Siemens WinCC system, nrog PLCs txuas nrog WinCC server ntawm Industrial Ethernet network. Kev sib txuas lus ntawm PLCs thiab cov khoom siv hauv teb yog ua los ntawm PROFIBUS DP raws tu qauv; Txhua PLC nta ntau yam PROFIBUS DP interfaces mob siab rau txuas cov chaw taws teeb I/O modules, tsav systems, encoders, teb instrumentation, nrog rau CPC thiab EPC li. Lub tshuab hluav taws xob hloov hluav taws xob, zoo ib yam li lub tshuab coil slitting, yog tswj los ntawm ib qho CPU416-2 module-interfacing nrog ob qhov sib cais PROFIBUS DP networks-kom ua tiav cov haujlwm suav nrog kev hloov kho qhov dav, sib tshooj hloov kho, thiab kev hloov kho sab nraud.

Optimization ntawm Mechanical Clearance Elimination Function rau Rotary Shear

Kev sib hloov ntawm lub cev muaj zog tsav cov ntsia hlau txhuas, uas ib txhij tsav lub encoder; Cov lus tsa suab no tau hloov mus rau hauv qhov kev hloov pauv sab nraud ntawm lub teb shear tuav, yog li ua kom qhov kev hloov pauv ntawm lub teb shear sab clearance. Vim lub hauv paus clearance ntawm cov txiv ntseej thiab cov hlau lead ntsia hlau, thaum cov kev taw qhia ntawm kev sib hloov hloov los ntawm pem hauv ntej mus rau thim rov qab, lub taub hau ntsia hlau thiab encoder pib tig ua ke thaum lub txiv ntseej tseem nyob ruaj ruaj, ua rau tsis muaj kev txav ntawm lub shear tuav. Qhov tshwm sim no- qhov chaw sensor pom qhov hloov pauv ntawm txoj haujlwm txawm tias qhov tseeb ntawm lub cev tsis tau hloov pauv - yog tshwm sim los ntawm cov khoom siv rov qab los ntawm cov khoom siv. Txij li thaum lub encoder tau calibrated nyob rau hauv lub "kaw" kev taw qhia, cov cuab yeej zaum kawg txav yog tsis tu ncua ua nyob rau hauv lub kaw kev taw qhia kom tshem tawm cov kev tswj txoj hauj lwm yuam kev tshwm sim los ntawm lub aforementioned mechanical backlash. Piv txwv li, kom txav los ntawm txoj haujlwm tam sim no (Point A) mus rau Point C, lub tshuab yog thawj zaug qhib rau Point B thiab tom qab ntawd kaw rau Point C.

Txhawm rau kom ua tiav qhov kev tswj xyuas siab, kev hloov kho ntawm qhov sib tshooj thiab sab clearance rau lub teb txiab-nrog rau kev tshem tawm kev hloov kho rau cov seem chopper- siv cov txheej txheem hauv qab no: thaum twg lub hom phiaj tus nqi siab tshaj tus nqi tam sim no, qhov kev ncua deb yog thawj zaug kho rau tus nqi siab dua li lub hom phiaj, thiab maj mam kaw rov qab mus rau lub hom phiaj tus nqi. Peb tau muab cov kev pab cuam thaiv kev hloov kho tsis siv neeg tshem tawm mus rau hauv PLC software; los ntawm kev sib koom ua ke nrog qhov kev tswj hwm ntawm tus qauv tsim thiab siv cov ntsiab lus kaw - voj tswj tshuab-tshwj xeeb los ntawm lub sijhawm tiag tiag - kev soj ntsuam ntawm cov encoders kiag li - peb tau ua tiav tsis yog tiag tiag - lub sij hawm tawm tswv yim ntawm cov tshuab tshem tawm ntawm lub tshuab hloov pauv, tab sis kuj hloov qhov tseeb, tsis siv neeg hloov. Txij li thaum siv cov kev txhim kho no, qhov tseeb ntawm qhov kev hloov kho clearance tau ua tiav cov kev xav tau ntau lawm, ua kom muaj txiaj ntsig ntau lawm thiab ua kom zoo thiab du ntawm cov txheej txheem shearing.

Ntawm - qhov kev tshwm sim ntau lawm qhia tau hais tias qhov kev tswj hwm rau Ma Steel pickling kab lub teb shear yog automated, txhim khu kev qha, thiab yooj yim rau kev khiav lag luam, thaum tseem txo cov kev siv zog. Nws tau txhim kho shearing zoo thiab kev ua haujlwm ntau lawm, ua tau raws li qhov yuav tsum tau ua thiab tsim cov txiaj ntsig kev lag luam tseem ceeb.
