TL; DR:Tanged hlau xov inserts raug nqi tsawg, nkoj nyob rau hauv qhov ntau thiab tsawg mus txog M48, thiab zam lub qhov av. Tangless inserts tshem tawm FOD kev pheej hmoo, teeb tsa bidirectionally, thiab dominate aerospace ua hauj lwm, tab sis cap ntawm M16. Xaiv tanged rau tus nqi - tsav tsheb kho kev lag luam. Xaiv tangless thaum ib tug xoob tang tawg nyob rau hauv ib feem yog tsis tsim nyog.

Qhov tseeb txawv
Ob leeg yog qhov tseeb- dov stainless hlau coils nrog lub pob zeb diamond cross-section, ntsia rau hauv STI-tapping qhov. Lub ntsiab lus txawv tsuas yog qhovtsav feature.
- A tanged ntxigmuaj ib tug tab nyob rau hauv qab coil. Lub mandrel tsav nws nyob rau hauv, ces koj snap lub tab nrog ib tug punch thiab retrieve lub fragment.
- A tangless ntxigmuaj ib tug ntswj ntawm lub coil sab saum toj. Ib tug prewinder ntxiv rau tus tsav tsheb koom los ntawm qhov qhib kawg thiab screws nws. Tsis muaj dab tsi tawg.
Qhov kev sib txawv ntawd ua rau txhua qhov sib txawv.
Vim li cas FOD yog qhov kev txiav txim siab tiag tiag
Nyob rau hauv aerospace, FOD (Foreign Object Debris) yog ib daim ntawv teev cov kev pheej hmoo, thiab ib tug xoob tang nyob rau hauv lub cav vaj tse tsis ua hauj lwm NADCAP soj ntsuam. Lub tanged workflow txo qhov txheej txheem no (nqus, suav phaib, borescope dig qhov qhov), tab sis nws ntxiv lub nra hnyav. Tangless tshem tawm hom tsis ua hauj lwm los ntawm kev tshem tawm qhov tawg. Tias yog vim li cas lub cav dav hlau OEMs thiab cov cuab yeej siv kho mob tau hloov M16-thiab-ua haujlwm me me kom tsis muaj teeb meem.
Yog tias koj cov khoom lag luam tsis muaj dab tsi txav mus rau hauv nws (cov khoom lag luam mining, cov khoom siv hluav taws xob, cov khoom siv sab nraum zoov), FOD kev pheej hmoo yog kev kawm thiab cov nqi them nqi tsis raug cai.
Kev ua tau zoo thiab kev teeb tsa
Kev txhim kho lub zog yog qhov tseem ceeb zoo ib yam. Ib qho M8 304 stainless ntxig rau hauv 6061-T6 txhuas (15 hli kev koom tes) nqa kwv yees li 28 txog 32 kN rub tawm, zoo tshaj qhov pov thawj ntawm qib 8.8 M8 ntsia liaj qhov rooj. Kho ob hom zoo li mechanically sib npaug.
Qhov twg lawv diverge yog lub sij hawm voj voog. Tanged installs khiav 25 mus rau 40 vib nas this ib qhov ntxig (qhov so -tawm thiab retrieval ntxiv variability). Tangless khiav 12 mus rau 20 vib nas this uas tsis muaj qhov suav. Ntawm cov neeg siv khoom peb ntsuas ntawm 18,000 ntxig rau ib hlis, hloov mus rau tangless txiav txog 90 tus neeg teb xov tooj-teev ib hlis thiab poob tag nrho cov nqi- hauv- qhov los ntawm 14%, txawm tias tus nqi siab dua.
Kev ntes nrog tangless: nws xav tau lub qhov huv si, qhov tseeb ntawm STI qhov. Tanged yog kev zam txim ntau dua, uas yog vim li cas cov khw kho khoom ua haujlwm ntawm cov neeg siv khoom tsis paub txog qhov xwm txheej tseem ua rau nws.
Thaum twg xaiv qhov twg
Xaiv tangedthaum tus nqi tseem ceeb tshaj plaws, thaum koj xav tau qhov ntau thiab tsawg dua M16, thaum lub qhov zoo sib txawv, lossis thaum FOD tsis yog qhov yuav tsum tau ua.
Xaiv tanglessThaum cov khoom raug kaw lossis muaj cov khoom txav mus los, thaum tus neeg siv khoom qhia NASM8846 lossis NAS1130, thaum lub ntim ntim siab txaus uas lub sijhawm ua haujlwm tseem ceeb, lossis thaum lub ntxig yuav tsum tau muab tshem tawm thiab hloov hauv kev pabcuam.
FAQ
Puas yog tanged thiab tangless inserts interchangeable nyob rau hauv tib lub qhov?
Yog, rau tib lub nominal loj. Ob leeg siv tib yam STI kais thiab cov kauj vab geometry yog zoo tib yam. Tsis muaj re-tapping yuav tsum tau sib pauv.
Dab tsi yog qhov loj tshaj plaws tangless insert muaj?
M16 / 5/8"-11 los ntawm cov tuam txhab tseem ceeb. Qhov loj dua yog qhov tshwj xeeb-kev txiav txim nrog lub sij hawm txhuas ntau tshaj 12 lub lis piam.
Puas yog "Heli-Coil" zoo ib yam li cov xov hlau ntxig?
Heli-Coil yog hom (Stanley Engineered Fastening). Lub sij hawm generic yog "wire thread insert." Peb thiab ob peb lwm cov tuam ntxhab tsim qhov sib npaug sib npaug rau tib cov qauv.
Kuv puas xav tau tus kais tshwj xeeb?
Yog lawm, tus kab mob STI kais, uas ua rau lub qhov roughly 6% loj dua lub nominal xov txoj kab uas hla. Tus qauv kais yuav tsis ua haujlwm.
Cov ntsiab lus
Tanged thiab tangless hlau xov inserts xa tib lub zog txhim kho tab sis teb cov lus nug sib txawv. Tanged yeej ntawm tus nqi thiab qhov loj me (txog M48). Tangless yeej ntawm FOD tshem tawm, nruab nrawm, thiab ntawv pov thawj aerospace. Qhov kev txiav txim siab tsis tshua muaj zog, nws yog hais txog qhov koj yuav tsum tau ua tom qab nws tawm hauv pem teb.
