Muaj ntau hom wiers, thiab lawv muaj ntau hom kev siv, thiab yog ib qho kev sib tw tes rau pinching thiab shearing workpieces nyob rau hauv ntau yam kev lag luam, kho thiab teeb tsa. Tab sis nws muaj ib qho qauv txheej txheem yooj yim, uas yog, txhua lub nroog pliers uas muaj nyob ntawm peb ntu: Daim Npav, Pin thiab Kov. Lub hauv paus ntsiab lus ntawm cov pob muaj ob lub levers, ntawm ib qho taw tes hauv nruab nrab, yog li ntawd ob qho kawg tuaj yeem txav ntawm tes, lwm qhov kawg tuaj yeem nres cov khoom. Txhawm rau kom txo cov quab yuam siv los ntawm tus neeg siv thaum lub sijhawm ua haujlwm, yog li ntawd lub zog clamping tuaj yeem tau nrog kev quab yuam tsawg dua kom tau raws li kev yuav tsum tau siv.
Peb feem ntawm cov pliers yog raws li hauv qab no:
Ib khub ntawm tes rau gripping. Lub ergonomically tsim kov ua rau nws yooj yim los tuav kom ruaj khov thiab xis. Txuas ncej, uas yog qhov txuas txuas ntawm lub pliers. Daim Ntawv Txuas Yuav Tsum Txav mus yuav tsum txav tau zoo yam tsis muaj kev tso tseg, ua rau nws qhib tau yooj yim lossis kaw cov ntaub ntawv nrog ib sab tes. Cov pliers taub hau yog nruab nrog lub qhov ncauj clamping lossis txiav ntug. Lub pliers yog nyob rau hauv av rau txoj cai zoo. Qhov ob shear npoo (nrog springs) yuav tsum yog ntse heev thiab meej kaw rau ib leeg kom yooj yim txiav lub xaim.
Qhov no hloov dua siab dua lub zog sab nraud (xws li xuas tes ua thov rau lub pob zeb npab) mus rau lub zog loj, cia cov pleiver, cia cov pleively. Thaum lub zog sab nraud tau thov rau lub caj npab clamp ntxiv nrog kev sib zog, lub zog ntawm clamp nozzle tsim lub zog sab nraud uas tau txav lub clamp. Yog tias lub zog loj sab nraud yuav tsum tau tsim, qhov deb ntawm qhov chaw ntawm lub plawv riveting txoj hauj lwm yuav tsum tau, thiab qhov kev ncua deb ntawm lub chaw riveting yuav tsum yog luv li sai tau. Txawm li cas los xij, muaj ntau tus neeg lub pob tsis nce ntxiv ntawm cov khoom siv zog vim tias lawv tsuas yog ua kom yooj yim rau cov khoom siv nyuaj thiab hluav taws xob thiab cov ntaub ntawv engineering thiab thev naus laus zis
Daim hlau feem ntau yog forged los ntawm alloy thiab unalloyed qauv txheej txheem hlau. Rau cov dav dav dav hlau, lawv tau ua los ntawm high- Zoo carbon cov hlau nrog cov ntsiab lus carbon nrog 0.45%. High - Zoo thiab hnyav - Weart} Cov ntsiab lus muaj los ntawm cov roj carbon cov ntsiab lus xws li chromium lossis vanadium.
Lub hauv paus pib ntawm cov pliers nyob rau hauv Europe hnub rov qab mus rau ntau tshaj ib txhiab BC, thaum tib neeg pib casting hlau. Thaum lub sij hawm cov txheej txheem casting, cov pob muaj siv tau los tuav cov hlau hlau kub. Cov duab ntawm cov nplais ntawm cov lus yav dhau los tau tshwj tseg rau hnub no, thiab me ntsis tau hloov. Qhov ntau yam ntawm cov pliev tau nthuav dav nrog kev txhim kho ntawm handicrafts, lag luam thiab muaj kev lag luam. Lub clamp dav dav tau tsim los rau 100 hom. Tus naj npawb ntawm clams rau cov ntawv thov tshwj xeeb kuj nce ntxiv. Ntawm chav kawm, cov pliiv tshwj xeeb tsis muaj nyob rau hauv lub universal ntau. Nws yog qhov tsuas yog ib qho hauv lub teb chaws Yelemees nrog kev tawm hauv txhua hli ntau dua 1 lab tus nplaig, thiab li 50% ntawm nws yog xa tawm. Feem coob ntawm lawv yog General - lub hom phiaj pliers, xws li shear lub tshuab nqus tsev, hlau cutters thiab lub twj tso kua twj vov tsev.
Hais txog cov yam ntxwv, qhov sib txawv yog raws li hauv qab no:
(1) shear lub tshuab nqa khoom, uas tuaj yeem siv rau kev txiav lossis txiav (sib txig sib txig (txiab, pruners, thiab lwm yam).
(2) Cov hlau cutters, uas tuaj yeem siv rau shearing thiab clamping (hlau cutters (crane lub tshuab txiav, hluav taws xob, thiab lwm yam).
Hais txog cov qauv txheej txheem, qhov sib txawv tau muaj raws li hauv qab no:
(1) Pob txha taub hau, xws li Woodworking pliers. Lawv tau teeb tsa nyob rau sab saum toj ntawm cov ntaub ntawv thiab tsis tas yuav siv milling thiab riveting.
(2) Ib leeg shear sib ntswg, xws li cov hlau cutters. Milling cov pob qij txha mus rau zeb ib nrab ntawm cov tuab tuab kom ob daim ntawm cov plever yog muab tso rau hauv txhua lwm yam rau kev teeb tsa.
(3) Casing hom sib ntswg, ib tug kov muaj qhov zawj ntawm nws, cia lwm tus kov dhau los ntawm cov zawj, thiab ntswj ntawm kev sib koom ua ke. Casing elev -}}} puas muaj nqi ntau dua rau kev tsim khoom vim tias lawv nyuaj heev rau cov hlau tawv. Yog li ntawd, piv nrog thawj ob txoj kev sib tw sib ntswg, nws yog qhov sib txawv.
