Ib - nres Hlau Shear Factory hauv Suav teb
Cov hniav ntawm koj cov hlau shear (nqaj, guillotine, los yog seem) yog ib qho tseem ceeb tshaj plaws hnav tivthaiv. Lawv lifespan ncaj qha dictates koj cov nqi khiav hauj lwm, productivity, thiab txiav zoo. Hloov cov hniav ntxov ntxov yog qhov tseem ceeb, kev zam tsis tau.
cov tswv yim los ua kom lub neej ua haujlwm siab tshaj plaws
Pib nrog Txoj Cai Hniav: Lub Hauv Paus ntawm Kev Ntev
Cov hniav cov khoom muaj pes tsawg leeg thiab kev kho cua sov yog qhov tseem ceeb tshaj plaws. Tsis txhob siv generic lossis off-spec cov hniav kom txuag tau tus nqi ua ntej.
Premium Blade Materials:
Cov cuab yeej hlau (D2, A2, S7): Zoo heev rau cov khoom seem, muab qhov sib npaug ntawm qhov tawv thiab tawv.
High-Carbon, Siab-Chrome Steels (xws li A8 Hloov Kho): Kev lag luam tus qauv rau hnyav-cov haujlwm seem shearing. Muab superior hnav tsis kam.
Los ntawm -Hardened Alloy Steels (AR500, T-1): Feem ntau yog siv rau cov hlua khi thiab hnav daim hlau, thiab qee zaum rau cov hniav sib tsoo, muab kev tiv thaiv zoo heev.
Dab tsi los thov los ntawm koj tus neeg muab khoom:
Kev kho cua sov kom zoo: Cov hniav yuav tsum dhau los ntawm- tawv (tsis yog saum npoo- tawv) rau qhov tshwj xeeb Rockwell C hardness (HRC)- feem ntau ntawm 52-58 HRC. Siab hardness resists hnav tab sis yog nkig ntau dua; qhov zoo tagnrho yog qhov sib npaug.
Precision Sib Tsoo: Ntug yuav tsum yog hauv av, tsis yog nplaim taws- txiav, kom paub meej qhov tseeb thiab huv, kev ntxhov siab-dawb ntug.
Txoj Cai Golden ntawm Kev Ua Haujlwm: Sib piv cov shear rau cov khoom
Qhov no yog # 1 ua rau cov hniav tsis ua haujlwm ntxov. Lub shear tsis yog universal cutter.
Paub Koj Qhov Peev Xwm Shear: Tsis txhob tshaj qhov siab tshaj plaws thickness thiab hardness ntsuam xyuas rau koj tus qauv shear tshwj xeeb. Shearing cov khoom uas tuab dhau los yog tawv (xws li cov hlau tawv, cov cuab yeej hlau) yuav ua rau tawg tam sim ntawd lossis tawg.
Zam "Cov kab mob": nruj me ntsis tshem tawm cov tungsten, manganese hlau, cov khoom siv abrasive (paj rwb, pob zeb), lossis lwm yam tsis yog -ferrous hlau los ntawm koj cov kwj dej. Cov ntaub ntawv no yuav rhuav tshem cov npoo npoo.
Txiav Parallel mus rau Hniav: Rau lub kaum sab xis hlau los yog raws, taw qhia cov khoom kom cov hniav txiav tiaj tus rau saum npoo, tsis yog ntawm lub ces kaum. Txiav ntawm ib lub ces kaum concentrates quab yuam thiab ua rau notching.
Kev Saib Xyuas Txhua Hnub & Txhua Lub Limtiam: Tiv Thaiv Kev Nyuaj Siab Hnav
Txhua hnub (Pre-Shift):
Kev Ntsuam Xyuas Kev Pom Zoo: Tshawb xyuas cov nicks, chips, lossis cov kab nrib pleb ntawm qhov txiav. Ib nti me me yuav nthuav tawm sai sai rau hauv qhov tawg loj.
Ntxuav Cov Hniav: Siv txhuam txhuam los tshem cov hlau nplua, nplai, thiab cov khib nyiab ntawm cov hniav ntsej muag thiab cov rooj zaum. Ua-cov khib nyiab misaligns qhov txiav thiab ua kom nrawm hnav.
Kos Hniav Alignment & Gap: Xyuas kom cov hniav txav mus rau qhov sib npaug ntawm cov hniav ruaj khov. Kho cov hniav tshem tawm (qhov sib txawv) raws li cov chaw tsim khoom tshwj xeeb rau cov khoom tuab (feem ntau 5-10% ntawm cov khoom tuab). nruj heev qhov sib txawv ua rau galling thiab hnav ntau dhau; qhov sib txawv dhau los ua rau tus neeg pluag, ragged txiav uas qaug zog ntawm cov hniav.
Txhua lub lis piam:
Lubricate Pivot Points: Roj tag nrho cov pins, bushings, thiab tuav -downs. Ib qho yooj yim, pub dawb- txav tshuab tiv thaiv kev ua haujlwm tsis zoo uas cuam tshuam cov hniav.
Tighten Fasteners: Tshawb xyuas thiab torque tag nrho cov hniav mounting bolts. Kev vibration los ntawm shearing yuav loosen lawv.
Daim duab ntawm Sharpening: Thaum twg thiab Yuav Ua Li Cas
Tsis txhob tos kom txog thaum cov hniav yog dull. Ntsej muag ntawm lub sijhawm zoo rov qab ua haujlwm thiab tsis tshua muaj zog dua li kev kho kom zoo nkauj ntug.
Thaum Ntxov:
Kev ua tau zoo-Raws li: Thaum koj pom tias muaj qhov nce ntxiv ntawm qhov yuav tsum tau txiav quab yuam, "burr" ntau dhau ntawm qhov txiav, los yog deformed txiav ntug.
Teem sijhawm-Raws li: Tom qab ib lub nras (piv txwv li, txhua 500 tons) raws li koj cov ntaub ntawv keeb kwm.
Yuav Ua Li Cas Kho Kom Zoo:
Tshem Cov Hniav: Txhua zaus txhuam cov hniav tawm ntawm lub tshuab kom raug thiab nyab xeeb.
Khaws Lub Ntsiab Tseem Ceeb: Siv lub Hoobkas ntug bevel kaum sab xis (feem ntau 80-85 degrees). Hloov lub kaum sab xis tsis muaj zog ntawm ntug.
Siv Slow, Txias Grind: Tsis txhob overheat cov hniav. Siv ib qho qis -RPM ntub dej grinder lossis lub tshuab ntxhua khaub ncaws nrog cov dej txias ntau zaus. Overheating (ua rau xiav temper xim) rub lub hardness (temper) tawm ntawm cov hlau, tsim ib qho chaw mos uas yuav hnav sai heev.
Tshem Tawm Cov Khoom Siv Tsawg: Tsuas yog zom kom txaus los rov-tsim kom huv, txuas mus ntxiv. Lub hom phiaj yog tshem tawm cov nicks thiab rov ua kom zoo dua qub, tsis yog kho cov hniav.
Daim Ntawv Pov Thawj Zoo: Xyuas kom meej txawm tias cov khoom tshem tawm thoob plaws tag nrho cov hniav ntev kom tswj tau qhov flatness.
Kev Sib Hloov & Kev Tswj: Lub tswv yim "Four-Edges".
Feem ntau cov plaub hau txiav plaub hau muaj plaub qhov kev siv tau (ob leeg rau ib rab, sab saum toj thiab hauv qab).
Ua raws li Lub Sijhawm Sib Tw: Tom qab ua kom lub ntsej muag thawj zaug, tig cov hniav 180℃kom siv cov ntug sab nraud. Thaum ob lub npoo ntawm ib sab yog hnav, tig cov hniav kom siv ob lub npoo ntawm lwm sab.
Khaws Daim Ntawv Teev Npe: Taug qab ntug twg yog siv, tonnage processed, thiab sharpening hnub. Cov ntaub ntawv no pab kwv yees lub neej ntawm cov hniav thiab teem caij saib xyuas kom zoo.
Ib puag ncig & kev ua haujlwm zoo tshaj plaws
Tsis txhob poob siab Loading: Tsis txhob "poob shear" los yog siv lub shear ua rauj. Pub cov ntaub ntawv smoothly thiab cia lub hydraulic system ua hauj lwm.
Khaws kom huv: Tiv thaiv kom tsis txhob muaj plua plav thiab grit nkag mus rau hauv cov hniav.
Cia: Khaws cov hniav seem nyob rau hauv qhov chaw qhuav, kev txhawb nqa (tsis nyob ntawm lawv ntug) kom tsis txhob xeb thiab warping.
