Xov- Xaus Configuration & Core Design Logic
Ob chav End Stud yog ib lub cylindrical fastener nrog machined sab nrauv threads ntawm ob qho kawg thiab ib tug du, unthreaded shank nyob rau hauv nruab nrab. Tsis zoo li kiag lithreaded studs,peb qhov no - cheeb tsam tsim faib cov kev ua haujlwm fastening rau hauv ob qho kev ywj pheej interfaces: ib qho threaded kawg koom nrog ib lub qhov tapping nyob rau hauv lub party tivthaiv, thaum lub opposite kawg txais ib tug txiv ntseej rau clamp lub mating ib feem.Qhov chaw dumuab raws li ob qho tib si cov ntaub ntawv qhia meej meej thiab kev ntxhov siab- thaj chaw nyem, uas yog ob lub luag haujlwm engineering uas lub cev threaded tag nrho ua tsis tau ib txhij.
Peb-Zone Architecture: Threaded Ends & Smooth Shank
Ib tug zoo ob chav kawg stud ntawm hom no faib cov khoom siv thauj khoom hla peb thaj chaw ua haujlwm sib txawv, txhua tus nrog nws tus kheej qhov ntev thiab qhov chaw- ua kom tiav:

Ntsiab -CNC Tolerance Standard |
|
Coj mus rhaub End (Fixed End) |
Permanently ntsia rau hauv ib tug tapped qhov. Cov xov hauv chav kawm thiab qhov ntev ntawm kev sib koom ua ke yog tsim los tiv thaiv kom tsis txhob xoob ntawm lub voj voog tsis muaj kev vam khom nkaus xwb ntawm cov xov -locking compounds. |
Xov suab Ø: ± 0.02 hli; Kev sib txuas ntev: ib daim duab ± 0.25 hli |
|
Smooth Shank (Center) |
Ua haujlwm raws li tus neeg tsav tsheb sib dhos thaum lub sijhawm sib dhos thiab kev ntxhov siab-txoj kev nyem uas cuam tshuam txoj xov txuas txuas ntxiv. Qhov geometry no txo qis rhiab heev ntawm cov xov - theem hauv paus thiab txhim kho lub neej qaug zog piv rau cov qauv tsim tag nrho. |
Shank Ø kam rau ua: h8 / h9; Nto tiav: Ra 0.8-1.6 μm; Concentricity rau xov axis: Tsawg dua los yog sib npaug rau 0.03 hli |
|
Nut End (Clamping End) |
Txais cov txiv ntseej nruj. Xov ntev tau teev tseg kom haum rau cov txiv ntseej qhov siab ntxiv rau lub tshuab ntxhua khaub ncaws ntxiv rau ob lub xov tag nrho ntawm kev sib tw rau cov txiv ntseej tag nrho. |
Xov suab Ø: ± 0.02 hli; Txiv ntseej kawg chamfer: 30℃± 2℃ib ISO 4753 |
Lub hauv paus shank tsis yog "unthreaded bar stock." Nws txoj kab uas hla, deg roughness, thiab concentricity rau cov xov axis yog tswj tsis tau ntawm Key-CNC. Rau flange cov rooj sib txoos uas yuav tsum tau muab tso rau ib txhij ntawm ntau lub studs los ntawm gasket- sib cais mating ntsej muag, ib tug meej hauv pem teb shank txo qhov kev sib hloov quab yuam thiab tiv thaiv gasket puas thaum sib dhos - qhov teeb meem zoo uas tag nrho threaded studs, nrog rau lawv cov xov nruam crests, routinely ua.
Dimensional Range & Xov Standards
Cov precision ob qhov kawg studs yog tsim los rau koj daim ntawv thov, los ntawm M3 me me hardware rau lub chaw soj nstuam theem mus rau M36 hnyav-duty studs rau industrial flange sib txuas. Cov txheej txheem ntau lawm tsis yog:
Txoj kab uas hla:M3 - M36 (metric) # 4 - 1-1 / 2 "(Imperial)
Zuag qhia tag nrho Length:10 mm - 500 mm standard Lwm qhov ntev muaj nyob ntawm kev thov
Xov StandardsISO metric coarse (M profile) ISO metric nplua suab UNC UNF UNEF
Xov kam rau ua:6g (tus qauv sab nraud); 4g6g lossis 6h rau kev txiav txim siab
Shank Surface tiav:Ra 0.8 μm (tus qauv); Ra 0.4 μm (qib meej)
Concentricity ntawm Shank:<0.03 hli rau axis ntawm xov mus txog M16; Tsawg dua los yog sib npaug li 0.05 hli rau M20 thiab loj dua
Xov dovyog thawj txoj kev tsim khoom rau cov studs ntawm nruab nrab mus rau siab ntau lawm. Txias-tsim threads txav cov khoom es tsis txhob txiav nws, muab ib tug nruam grain ntws raws li cov xov profile - qhov no muab roughly 20-30% qaug zog zog dua txiav threads ntawm tib geometry. Tib -taw tes CNC xov txiav yog siv rau kev txiav txim siab ntim tsawg, cov khoom sib txawv (Titanium, Inconel) thiab cov xov zoo tshaj 1.0 hli suab. Hauv -txheej txheem kev soj ntsuam ntawm kev hnav ris tsho yog ua los tswj lub suab ntawm txoj kab uas hla zoo ib yam thoob plaws hauv ntau.
Kev xaiv khoom & Nto tiav
Kev xaiv cov khoom siv rau ob chav kawg Stud Lub galvanic compatibility ntawm stud, tapped qhov niam txiv cov khoom thiab cov txiv ntoo yuav tsum tau muab rau hauv siab. Piv txwv li ib lub stainless stud nyob rau hauv ib lub tsev nyob aluminium generates ib tug galvanic cell nyob rau hauv lub xub ntiag ntawm noo noo. Aluminium vaj tse ua lub sacrificial anode. Cov neeg ua haujlwm engineering ntawm Key-CNC yuav tom qab ntawd txheeb xyuas cov teeb meem sib raug zoo li no thaum lub sijhawm ntsuas DFM thiab muab cov txheej txheem txo qis xws li txheej txheej saum npoo, cais cov ntxhua khaub ncaws lossis lwm yam khoom siv ua ke.

Tag nrho cov khoom tsim tawm tuaj nrog tag nrho cov ntaub ntawv traceability nrog rau cov ntaub ntawv kuaj zeb (MTR), cov ntawv pov thawj kub ntau thiab cov ntawv pov thawj ntawm kev ua raws li cov ntaub ntawv txheem.
Mounting Torque thiab kev sib dhos zoo tshaj plaws
Lub fastener yog ob kauj ruam, kais kawg lub rooj zaum nyob rau hauv lub party tivthaiv thiab lub clamping kawg txiv ntseej yog torqued. Tsis meej pem qhov torque tsis tau los ntawm theem mus rau theem feem ntau yog qhov ua rau kev ua tsis tiav.
● Theem 1: Coj mus rhaub End Installation: Rooj zaumlub xub pwg nyomtiv thaiv lub ntsej muag mating nyob rau hauv kev tswj torque tsis loosing threads. Qhov tseem ceeb yog 30-50% ntawm cov ntawv pov thawj-load torque. Siv tus tsav tsheb, tsis txhob muab ob npaug rau txiv ntseej koj yuav ua rau cov txiv ntoo kawg threads thiab gall stainless fasteners.
● Kauj Ruam 2: Tighten txiv ntseej rau kev sib dhos torque.Hauv kev ua haujlwm no, ob qhov kawg stud tsis tig thiab lub ntsia liaj qhov rooj yuav tsum kov yeej kev sib txhuam hauv qab thiab yuav luag tag nrho cov ntawv thov torque raug xa mus rau clamping preload. Lub torque-rau-preload efficiency ntawm qhov tsim no yog ib qho zoo heev engineering kom zoo duahex boltsrau gasketed flange kev twb kev txuas.
Lubrication Note: Thaum lub sij hawm RFQ thov qhia qhov tseem ceeb -CNC yog hais tias lub sib dhos torque muab raws li lubrication (ASME PCC-1 flange los ua ke txheej txheem). Cov xov ntawm cov txiv ntseej kawg tuaj yeem lubricated nrog lub thickness predetermined qhuav zaj duab xis lubricant kom ua tau zoo K-factors thoob plaws ntau lawm.
