1144 Steel U-LK107 Ncej - Khoom, Machining & Application Guide

Cov ntsiab lus ceev

Cov1144 Steel U-LK107 Ncejyog ib tug precision tig ncej ua los ntawm SAE/AISI 1144 (resulfurized, txias-kos carbon steel). Nws tau xaiv qhov twg lub zog siab, kev ua haujlwm zoo heev, thiab qhov ntsuas qhov ntev yuav tsum tau ua - cov kev siv ib txwm muaj xws li shafts, pins, thiab couplings rau industrial thiab automotive driveline Cheebtsam.

Cov khoom tseem ceeb specs (qhov kev yuav khoom yuav tsum paub)

Khoom siv:SAE/AISI 1144 (UNS G11440) - nruab nrab -carbon, resulfurized, feem ntau txias- kos. (steel-grades.com)

Tej yam khoom siv (txias-draw bar):siab tensile & yield txheeb ze rau qis - carbon steels; zoo qaug zog tsis kam rau dynamic ncej. Cov txiaj ntsig tseeb nyob ntawm qhov chaw muag khoom daim ntawv pov thawj - ib txwm thov MTR. (ZoM)

Kev txwv:tsis stainless - txwv corrosion kuj; welding feem ntau poob siab los yog yuav tsum tau tom qab-weld kho cua sov vim yog sulfur / resulfurization. (Metal Zenith)

Vim li cas 1144 rau U-LK107 ncej?

1144 muaj qhov sib npaug: nyob ze - steel lub zog nrog qhov tseem ceebzoo dua machinabilityntau dua li nruab nrab- carbon steels, uas txo cov sij hawm voj voog thiab cov cuab yeej siv rau tig shafts xws li U-LK107. Rau precision tig qhov chaw uas xav tau tsawg distortion tom qab machining, 1144 yog ib qho kev xaiv. (Metal Zenith)

Manufacturing sau ntawv - machining & dimensional control

Tig & tiav

Siv cov ntse carbide inserts thiab nruab nrab aggressive feed rates exploit 1144's machinability - aim to minimize heat at the cutting zone to txo ​​residual stress.

Tiav tiav: lub hom phiaj ntawm Ra (piv txwv li, 0.8 µm / 32 µin) nyob rau hauv ib los yog ob qho tag kis nyob ntawm txoj kab uas hla thiab ntev.

Tolerancing thiab runout

Rau precision shafts, qhia geometric tolerances: concentricity thiab runout (xws li, Tsawg tshaj los yog sib npaug rau 0.03 hli) thiab roundness aav tsim nyog rau mating Cheebtsam.

Rau ntev, slender U-LK107 shafts, hu tawm ncaj (mm ib 100 mm) thiab nto waviness los tswj kev co hauv kev siv driveline.

Kev ntxhov siab nyem & tswj kev cuam tshuam

Yog tias txias- rub bar yog siv, qhov cuam tshuam tsawg kawg yog qhov tseem ceeb - tseem, xaj cov khoom siv nrog microstructure zoo ib yam thiab thov kev ntxhov siab- kev xaiv nyem yog tias nruj ntev - ntev yuav tsum tau ua kom ntev. (ZoM)

(Cov tswv yim tswv yim: thov ib qho kev sim luv luv los ntsuas qhov offsets thiab cov nyiaj them rau cov cuab yeej yog tias koj tab tom txav cov khoom lag luam ntawm cov neeg muag khoom.)

Kev kho cua sov & nto tiav

Kev kho cua sov:1144 feem ntau yog siv raws li -yog (txias- kos). Los ntawm - hardening los yog quench - thiab - kub yog ua tau tab sis yuav tsum tau ceev faj tswj thiab muaj peev xwm muab khoom; ib txwm txheeb xyuas cov neeg kho tshuab tom qab kho cua sov. (steel-grades.com)

Common finishes:phosphate + roj, dub oxide, zinc plating, los yog nitriding (yog tias hnav tsis kam) - xaiv ib qho corrosion & hnav yuav tsum. Faj seeb: plating thickness cuam tshuam rau ncej kam rau ua - qhia ncej-plating dimension los yog tso cai rau sib tsoo tom qab txheej.

Daim ntawv teev kev tswj xyuas zoo (rau kev yuav khoom & tshuaj xyuas)

Khoom siv MTR:txheeb xyuas UNS G11440 / AISI 1144 muaj pes tsawg leeg & tus lej kub.

Daim ntawv qhia Dimensional:Daim ntawv qhia CMM tag nrho rau thawj tsab xov xwm thiab kev kuaj xyuas ntau lawm (inch, concentricity, runout).

Surface finish report:Ra ntsuas thiab plating thickness yog siv.

Kev kuaj Hardness:yog tias kev kho cua sov tau ua tiav.

Fatigue lossis balance test:xav tau rau rotating shafts los yog driveline qhov chaw.

Hom kev thov & cov txheej txheem xaiv

Zoo rau:industrial tsav shafts, couplers, pins, precision spindles qhov twg machinability thiab lub zog teeb meem. (Metal Zenith)

Zam thaum:nyob rau hauv ib puag ncig corrosive heev (siv stainless) los yog thaum welding nyob rau hauv lub tshav pob yuav tsum.

Ntawm tus neeg muag khoom specifications & "Stressproof" thov

Qee cov mills ua lag luam "Stressproof" variants (tswj txheej txheem nrog guaranteed ncaj). Yog tias qhov ncaj thiab qhov loj me yog qhov tseem ceeb rau U-LK107, qhia meej cov khoom siv Stressproof tseeb lossis thov daim ntawv pov thawj zeb - generic 1144 thiab Stressproof tsis zoo ib yam.
