Kais Kev Ntsuam Xyuas: Phau Ntawv Qhia rau Boosting Thread Cutting Efficiency los ntawm 300% los ntawm Kev Xaiv Yooj Yim mus rau Advanced Technology.
Nyob rau hauv lub tshav pob ntawm mechanical processing, Kais, raws li ib tug tseem ceeb lub cuab tam rau internal thread processing, ncaj qha txiav txim cov xov raug thiab ntau lawm efficiency. Los ntawm kev tsim thawj tus kais dej los ntawm Maudslay hauv UK xyoo 1792 mus rau qhov tshwm sim ntawm cov kais dej tshwj xeeb rau titanium alloys niaj hnub no, evolution keeb kwm ntawm cov cuab yeej txiav no tuaj yeem suav tias yog microcosm ntawm kev lag luam precision. Kab lus no yuav ua kom tob tob txog cov txheej txheem ntawm Tap los pab koj txhim kho tapping efficiency.
I. Lub hauv paus ntawm Kais: Hom Evolution thiab Cov Qauv Tsim Qauv
Cov kais dej tuaj yeem muab faib ua peb hom loj raws li txoj kev tshem tawm nti, thiab txhua hom sib raug rau cov txheej txheem sib txawv:
1.Triangular-point kais(Tip point tap): Xyoo 1923, nws tau tsim los ntawm Ernst Reime los ntawm lub teb chaws Yelemees. Lub hauv ntej kawg ntawm txoj kab ncaj nraim yog tsim los nrog txoj kab nqes, uas pab thawb cov chips rau pem hauv ntej kom tso tawm. Kev ua tau zoo ntawm lub qhov yog 50% siab tshaj qhov ncaj-groove kais, thiab lub neej kev pab cuam tau nce ntau dua ob npaug. Nws yog tshwj xeeb tshaj yog haum rau kev sib sib zog nqus xov ntawm cov ntaub ntawv xws li steel thiab cam khwb cia hlau.
2. Kauv zawj kais: Lub helical lub kaum sab xis tsim ua rau cov chips raug tso tawm mus rau sab saud, zoo kawg nkaus haum rau kev siv qhov muag qhov muag. Thaum machining txhuas, 30 ° helical lub kaum sab xis tuaj yeem txo qhov tsis kam ntawm 40%.
3. Extruded xov: Tsis muaj nti-tshem tawm zawj. Cov xov yog tsim los ntawm cov yas deformation ntawm cov hlau. Lub zog tensile ntawm cov xov yog nce los ntawm 20%, tab sis qhov tseeb ntawm lub qhov hauv qab yog siab heev (formula: hauv qab lub qhov taub = nominal txoj kab uas hla - 0.5 × suab). Nws feem ntau yog siv rau aerospace-qib aluminium alloy qhov chaw.
| Hom | Siv tau scene | Txiav ceev | nti tshem tawm kev taw qhia |
| Tswv yim tap | Los ntawm qhov | Kev kub ceev (150sfm) | Tom ntej |
| Kauv kais | Qhov muag qhov muag | Nruab nrab ceev | Upward |
| Xov sib sau kais | Cov khoom siv yas siab heev | Tsawg tshaj tawm | Tsis muaj |
Kev sib piv ntawm kev ua tau zoo ntawm peb hom kais dej
II. Cov khoom hloov pauv: Lub Leap ntawm High-Speed Steel rau Txheej Tshuab
Kev txhawb nqa tseem ceeb ntawm Tap qhov kev ua tau zoo yog nyob rau hauv cov khoom siv thev naus laus zis:
Kev kub ceev steel (HSS): Muaj nyiaj ntau dua 70% ntawm kev ua lag luam. Nws yog qhov kev xaiv saum toj kawg nkaus vim nws cov nqi-zoo thiab kev cuam tshuam zoo heev.
Hard alloy: Qhov tseem ceeb rau kev ua cov titanium alloys, nrog lub hardness tshaj HRA 90. Txawm li cas los xij, nws cov brittleness yuav tsum tau them nyiaj los ntawm kev tsim qauv.
Txheej technology:
Titanium Nitride (TiN): Kub-xim txheej, muaj ntau yam, lifespan nce 1 zaug.
Pob zeb diamond txheej: Txo kev sib txhuam coefficient los ntawm 60% thaum lub sij hawm ua cov txhuas alloys, thiab ncua kev pab cuam lub neej los ntawm 3 zaug.
Nyob rau hauv 2025, Shanghai Tool Factory launched titanium alloy-specific kais. Cov kais dej no muaj cov qauv tsim ntawm peb npaug arc groove ntawm ntu ntu (patent naj npawb CN120460822A), uas daws qhov teeb meem ntawm titanium chips adhering rau lub laum me ntsis thiab ua rau kom tapping efficiency los ntawm 35%.
III. Cov kev daws teeb meem rau cov teeb meem hauv kev siv kais: tawg shanks, cov hniav lwj, txo qis precision
1. Kev tiv thaiv kev tawg:
Hauv qab qhov sib txuam: Rau M6 threads, qhov xav tau hauv qab lub qhov taub hauv cov hlau yog Φ5.0mm (formula: Hauv qab qhov taub = Xov inch - Pitch)
Vertical alignment: Siv ntab chuck, lub kaum sab xis sib txawv yuav tsum yog ≤ 0.5 °.
Lubrication zoo: Qhov tseem ceeb roj-raws li kev txiav kua rau titanium alloy tapping, txo qhov kub ntawm 200 ℃.
2. Kev ntsuas kom txo qhov raug
Calibration department hnav: Tsis tu ncua ntsuas lub puab kab loj. Yog tias qhov kam rau siab tshaj IT8 qib, hloov tam sim ntawd.
Txiav tsis: Rau 304 stainless hlau, qhov pom zoo linear ceev yog 6 m / min. Pub ib lub kiv puag ncig = pitch × rotational ceev.
Kov hnav yog nrawm heev. Peb tuaj yeem ua kev sib tsoo ntawm Kais kom txo nws qhov hnav. Koj tuaj yeem tiv tauj peb kom paub meej txog cov ntaub ntawvKais sib tsoo tshuab.
IV. Kev Xaiv Golden Txoj Cai: 4 Lub Ntsiab Rau Kev Xaiv Tus Coj Zoo Tshaj Plaws
1.Los ntawm qhov / qhov muag tsis pom qhov: Rau los ntawm qhov, siv qhov sib tw twist drills (nrog rau cov khib nyiab ntawm sab pem hauv ntej); rau qhov qhov muag tsis pom kev, ib txwm siv qhov sib tw twist (nrog cov khib nyiab ntawm sab nraub qaum);
2. Khoom yam ntxwv: Hlau / Forged Hlau: HSS-Coated kais; Titanium Alloy: Carbide + Axial Internal Cooling Tsim;
3. Xov raug: Precision kho mob qhov chaw yog tsim los ntawm kev sib tsoo-qib kais dej (kev ua siab ntev IT6);
4. Kev txiav txim siab nqi: Chav tsev tus nqi ntawm extrusion kais yog 30% siab dua, tab sis tus nqi ib thooj rau cov khoom loj yog txo los ntawm 50%.
Los ntawm cov saum toj no, nws tuaj yeem pom tias Kais tau hloov zuj zus los ntawm cov cuab yeej dav dav rau hauv cov txheej txheem meej rau kev hloov kho qhov xwm txheej. Tsuas yog los ntawm kev paub txog cov khoom siv thiab cov qauv txheej txheem tuaj yeem ua rau txhua tus ntsia hlau xov dhau los ua cov txheej txheem caj ces rau kev sib txuas kom ntseeg tau.
