Hom ntawm cov ntaub ntawv: cov ntaub ntawv, kev khiav hauj lwm hauv paus ntsiab lus, kev siv

Sib Tsoo hlau cov khoom tsis yog ib txwm ua tau nrog kev pab los ntawm hluav taws xob cov cuab yeej. Feem ntau rau tej chaw ua hauj lwm ntxias siv ntau hom ntawm cov ntaub ntawv. Lawv yog cov, nyob rau hauv kev sib piv nrog hluav taws xob khoom, ntau nyob xeeb dua qub. Neeg ua hauj lwm seem ntawm ib tug loj ntau yam ntawm cov cuab yeej los mus xaiv tus kom tsim nyog cov ntaub ntawv uas yuav tsum tau machined. Nrog rau qhov no nws yog ib qho yooj yim los mus daws, yog tias koj paub lub zoo workmanship, tag nrho cov hom ntawm cov ntaub ntawv thiab lawv lub hom phiaj.

Yuav ua li cas yog cov ntaub ntawv?

Qhov cuab yeej no yog ib yam khoom uas muaj ob qhov chaw:

1. Steel bar. Nyob rau saum npoo ntawm ib tug tshwj xeeb Stencil notches. Tej zaum lawv yuav muaj ob peb yam kev xaiv. Feem ntau hom incisions ntawm cov ntaub ntawv - rectangular, voos thiab puag ncig.
2. Ntoo los yog yas kov. Nrog lub clamping nplhaib, kev tiv thaiv nws los ntawm ntes, nws yog mounted rau cov tapered shank. Tsim rau yooj yim ntawm kev siv ntawm ib cov ntaub ntawv. Thaum koj ua txhaum kov nws yog ib qho yooj yim los hloov. Zus tau tej cov chaw siv beech, birch thiab nias daim ntawv. Nws ntev yuav tsum tau yuav ib tug thiab ib tug ib nrab sij hawm ntau tshaj tus Tsov tus tw ntawm ib cov ntaub ntawv.

Lub cuab tam yuav muaj ntau ntau thiab tsawg. Tus txheem ntev yog 9, 10, 11, 12, 13 thiab 14 cm. Inch: 12, 16, 20, 23, 25 thiab 28 mm.

hauv paus ntsiab lus ntawm cov lag luam

Tag nrho hom ntawm cov ntaub ntawv teej tug mus rau tej cuab tam. Lawv yuav siv los tsim cov kev kawm ntau thiab tsawg thiab duab ntawm workpieces. Cov ntaub ntawv tsis stratified los ntawm kev sib tsoo chaw.

ntaub ntawv

Rau siv thiab ua cov ntsuas kev siv yog heev ruaj, high-qib cuab tam steel:

• Nyiaj Muas ShKh15 los yog 13X. Qhov no alloy chrome hlau.
• U10A thiab U13A. Cov hom zoo undoped.

Cov ntaub ntawv tsis tiav los ntawm hardening, whereby lub hardness ntawm 54-58 HRC. Cov qhab nia no yog siv rau zus tau tej cov ntaub ntawv npaj siv rau cov hlau tais diav. Rau cov ntoo thiab lwm yam ntaub ntawv los ntawm cov cuab yeej steel uas yog softer.

Tool nrog ib tug hluas notch

Qhov no notch (kuj hu ua yooj yim) raws li nyob rau hauv tshwj xeeb ntaub ntawv. Lub hom phiaj ntawm xws li ib tug uas yog qhov kev tshem tawm thaum lub sij hawm uas teev daim ntawv me hlau txheej. Tshwj xeeb ntaub ntawv yog siv los nqaim lub ua chaw. Lawv yog cov yooj yim rau hov lub kaw ntoo. Cov khoom no yog npaj rau siv rau cov mos mos hlau, ntoo thiab yas.

Cov khoom nrog ib tug ntoo khaub lig-section

Cov ntaub ntawv nrog ob thais, yog general-lub hom phiaj cov cuab yeej. Nyob rau saum npoo ntawm cov khoom no, lwm yam tshaj li lub ntsiab seem, muaj ntxiv. Lub ntsiab seem yog tsim los tshem tawm hais los ntawm lub workpiece thiab them nyiaj yug - zom lawv mus rau hauv tej daim. Cov ntaub ntawv ob (koom haum pab) incision siv thaum ua hauj lwm nrog cov khoom co thiab hlau alloys.

Cov ntaub ntawv nyob rau hauv cov hlau. hom

GOST 1465-59 - cov no yog cov qauv uas underpin zus tau tej cov Metalwork cov ntaub ntawv. Nyob ntawm seb qhov luaj li cas thiab tus naj npawb ntawm incisions nyob rau hauv tus nto ntawm 10 hli txawv nram qab no cov cuab yeej:

1. Tsaub. Cuab yeej nrog ib tug loj incision. 10 hli ntawm qhov chaw ntawm ib cov ntaub ntawv muaj rau 5-12 daim. Tus me tus xov tooj ntawm notches, tus loj dua cov hniav. Yog li ntawd, tsim ua ntau particulate tshem tawm thaum ua daim ntawv khoom.
2. Tej. Yog cov khoom uas muaj ib tug nruab nrab serration. Number ntawm cov hniav mus txog 25 daim.
3. Velvet. Cov no yog cov cuab yeej nrog lub me tshaj incision. Nyob rau saum npoo ntawm 10 mm rau 80 cov hniav.

Rau qhov yooj yim ntawm kev xaiv lwm lub cuab tam hom ntawm cov ntaub ntawv muaj lawv tus kheej chav tsev: bastard - №1, tus kheej - №2, velvet - №№3-6.

Classification cov cuab yeej nyob rau hauv zoo

Workpieces muaj ntau daim. Rau npaum lag luam ntawm tej khoom uas yog muab coj mus rau hom ntawm cov ntaub ntawv. Lawv txawv los ntawm ib lwm zoo ntawm lub profile (ntoo khaub lig-section). Paub qhov txawv cov nram qab no ntau ntau yam ntawm cov ntaub ntawv:

• tiaj;
• square;
• voos;
• puag ncig;
• semi-ncig;
• tshwj xeeb;
• riam-zoo li los yog hacksaw;
• pob zeb diamond;
• oval cov ntaub ntawv.

hom ntawm cuab yeej luv luv piav saum toj no. Yuav ua li cas lawv yog rau?

lub sij hawm

Pav ca cov ntaub ntawv siv los ua hauj lwm nrog cov convex thiab tiaj tus txheej los yog puab chaw. Lub square siv mus ua hauj lwm nrog square thiab lub qhov thiab slots. Xws li ib tug lub cuab tam no yog hu ua squaring. Nws ntev yog 35-50 cm. Nws yog zoo nyob rau hauv tus neeg mob thaum nws yog tsim nyog los tshem tawm cov hlau txheej yog ntau tshaj 1 hli. Trihedral ntaub ntawv siv thaum ua hauj lwm nrog cov ces kaum, grooves, qhov thiab grooves. Round yuav tsum tau mus teev tsab ntawv lub concave chaw. Siv mus ua hauj lwm nrog puag ncig thiab dawb qhov.

Cov ntaub ntawv siv rau tshwj xeeb ua ces kaum inclined thiab serrated chaw. Qhov no zoo ntawm cov cuab yeej yog sampled nqaim slots thiab grooves. DRACHEVO cuab yeej nruab nrog lub biggest hniav thiab yog npaj rau cov thawj nto kev kho mob, raws li nws tso cai rau kom sai sai tshem tawm ib tug loj txheej ntawm nws (0.05-0.1 hli). Nyob rau tib lub sij hawm, cov ntsia thawv ntaub ntawv muaj tsawg tseeb. Raws li ib tug tshwm sim, lub chaw ua hauj lwm nto daws roughly. Tej ntaub ntawv yog siv rau cov xov ntawv. Yog li muaj ib tug tshem tawm ntawm lub txheej thickness ntawm 0.02-0.06 hli. Velvet siv nyob rau hauv qhov kawg polishing theem. Nyob rau saum npoo ntawm cov khoom yog muab tshem tawm opilivaem thinnest txheej (0.01-0.03 hli). Cov ntaub ntawv muaj siab raug ntawm kev uas yog 0.01-0.005 hli.

rasp

Dhau li Metalwork ntaub ntawv rau cov zauv hlau thiab lwm qhov chaw siv rasps, uas txawv nyob rau hauv lawv cov notches. Lawv cov hniav loj loj luaj li cas thiab muaj tus duab ntawm pyramids, uas yog nyob qab tshwj xeeb grooves. Tus ntoo khaub lig seem ntawm qhov ntsuas muab tso nyob rau hauv kab perpendicular mus rau lub axis. Rasps siv nyob rau hauv qhov kev ntawm mos uas siv: txhuas thiab duralumin. Ua los ntawm steel qib U7A, U10A. Lawv hardness ntawm 35-40 HRC. Standard cov cuab yeej. Length: 25 mus txog 35 cm Rasps yog plaub hom: tiaj blunt, ntse-nosed tiaj tus, puag ncig, semicircular. Scope ntawm lub twj paj nruag - tshuaj thiab zus tau tej cov tin khoom.

Koob

Koob yog lub me tshaj cov ntaub ntawv. Npaj mus nqa tawm ib tug heev leej ua hauj lwm. Zus tau tej cov no cov cuab yeej siv steel qib U12 thiab U12A nrog ib tug hardness ntawm 54-60 HRC. Nyob ntawm seb tus ntoo khaub lig-sectional zoo Koob yog:

• pav ca (blunt thiab ntse-nosed);
• square;
• voos;
• puag ncig thiab ib nrab-round;
• oval;
• pob zeb diamond zoo li tus;
• grooving thiab hacksaw tuaj.

Handyman tas muaj tag nrho cov hom ntawm cov ntaub ntawv. Nws yog txaus kom muaj peb lub ntsiab - ib tug ca, voos thiab puag ncig. Nws tseem yog ntshaw kom muaj ib tug txheej ntawm koob cov ntaub ntawv thiab ib tug ob peb rasps. Nrog cov cuab yeej, koj yuav tau yooj yim daws nrog tej neeg ua hauj lwm uas txuam nrog cov hlau hniav sib tsoo.
