1. Txheej txheem cej luam

Lub JIS B 1360 (SPA1) Caij nplooj ntoos hlav Pin yog qhov tseeb -engineered fastener uas ua raws nraim li Japanese Industrial Standard (JIS) B 1360 specification. Muab faib raws li hom SPA1, lub caij nplooj ntoos hlav tus pin no yog tsim los rau cov ntawv thov kom txhim khu kev qha axial thiab radial tuav, zoo heev kev co kuj, thiab yooj yim installation. Nws leverages elastic deformation ntawm nws cov khoom los tsim kom muaj kev ruaj ntseg cuam tshuam nyob rau hauv lub mating qhov, kom ntseeg tau zoo ib yam nyob rau hauv ib tug ntau yam ntawm industrial thiab mechanical assemblies.

2. Txhais thiab Core Function

Lub caij nplooj ntoos hlav tus pin, tseem hu ua coiled caij nplooj ntoos hlav tus pin los yog yob tus pin, yog ib tug cylindrical fastener nrog ib tug split los yog slotted tsim. Hom SPA1, raws li tau hais los ntawm JIS B 1360, yog ib qho kev hloov pauv tshwj xeeb los ntawm nws cov phab ntsa tuab, qhov tseeb qhov ntev, thiab cov khoom ua kom zoo dua qub. Nws lub luag haujlwm tseem ceeb yog xa cov khoom thauj, nrhiav cov khoom, thiab tiv thaiv kev sib txheeb ntawm cov khoom sib dhos. Thaum ntsia, tus pin yog compressed kom haum rau hauv ib lub qhov me me dua nws lub nominal txoj kab uas hla; Thaum tso tawm, nws nthuav dav radially xauv rau hauv qhov chaw, tsim kom nruj, kev co- tiv thaiv kev sib koom ua ke yam tsis tas yuav tsum muaj cov fasteners ntxiv (xws li, txiv ntseej, bolts).

3. Cov qauv tsim thiab cov qauv tsim

JIS B 1360 (SPA1) Caij nplooj ntoos hlav Pin suav nrog ntau tus qauv tsim tshwj xeeb uas paub qhov txawv ntawm lwm hom fastener thiab xyuas kom nws ua tau zoo tshaj:

Split-Slot Design: Ib qho longitudinal split khiav tag nrho ntev ntawm tus pin, ua rau radial expansion thiab contraction. Qhov kev sib cais no yog qhov tseem ceeb rau kev ua tiav qhov cuam tshuam zoo thiab ua kom haum me me hauv qhov qhov ntev.

Uniform Phab Ntsa Thickness: Hom SPA1 yog tsim los nrog cov phab ntsa tuab zoo ib yam, uas ua kom muaj kev ywj pheej deformation thaum lub sijhawm teeb tsa thiab tiv thaiv kev ntxhov siab hauv cheeb tsam uas tuaj yeem ua rau ua tsis tiav ntxov.

Precision Cylindrical Profile: Tus pin nta ib tug du, cylindrical txheej txheej nrog nruj qhov ntev kam rau ua (raws li tau teev tseg hauv JIS B 1360) kom ntseeg tau tias kev sib raug zoo nrog tus qauv - qhov loj me thiab kev sib raug zoo nrog lwm cov khoom.

Chamfered Ends: Feem ntau SPA1 lub caij nplooj ntoos hlav pins tau nruab nrog chamfered (tapered) kawg, uas yooj yim rau kev nkag mus rau hauv lub qhov mating, txo qis kev siv zog, thiab txo qhov kev puas tsuaj rau lub qhov npoo.

4. Khoom siv thiab kev kho cua sov

Txhawm rau ua kom tau raws li cov kev xav tau ntawm kev ua haujlwm ntawm JIS B 1360, SPA1 Spring Pin feem ntau yog tsim los ntawm siab - zoo alloy steels lossis carbon steels, nrog rau cov ntaub ntawv hauv qab no thiab cov txheej txheem kho cua sov:

Cov ntaub ntawv hauv paus: Cov ntaub ntawv muaj xws li SWRCH (Cold Heading Steel Wire) qib, xws li SWRCH 18A, lossis hlau alloy xws li SCM435. Cov ntaub ntawv no raug xaiv rau lawv cov ductility zoo heev, tensile zog, thiab elastic rov qab zog, uas yog ib qho tseem ceeb rau tus pin lub caij nplooj ntoos hlav kev txiav txim.

Kev kho cua sov: Cov pins tau txais kev kho cua sov zoo, suav nrog quenching thiab tempering, kom ua tiav qhov nyuaj ntawm HRC 42-50 (raws li teev los ntawm JIS B 1360). Cov txheej txheem kev kho cua sov no txhim kho tus pin lub zog, hnav tsis kam, thiab elastic stability, kom ntseeg tau tias nws tuaj yeem tiv taus rov qab sib dhos / disassembly cycles thiab siv mus ntev hauv qhov xav tau ib puag ncig.

Kev kho saum npoo: Cov kev kho deg uas xaiv tau muaj xws li zinc plating, npib tsib xee plating, lossis xim dub oxide txheej. Cov kev kho mob no txhim kho corrosion kuj, txhim khu kev zoo nkauj tsos, thiab txo kev sib txhuam thaum lub sij hawm installation. Kev xaiv ntawm kev kho deg nyob ntawm qhov chaw thov (xws li, av noo, corrosive, lossis qhuav tej yam kev mob).

5. Dimensional Specifications (JIS B 1360 Standard)

Tus qauv JIS B 1360 txhais cov kev cai nruj me ntsis rau SPA1 Caij nplooj ntoos hlav Pin, nrog rau cov kab nominal, ntev, phab ntsa thickness, thiab kam rau ua ntau yam. Cov yam ntxwv tseem ceeb yog raws li hauv qab no (tus nqi raug; xa mus rau tag nrho JIS B 1360: 2006 tus qauv rau kev ua tiav cov lus qhia):

Nco tseg: Cov lus saum toj no teev ntau qhov ntau thiab tsawg; JIS B 1360: 2006 tus qauv npog ntau qhov dav ntawm nominal diameters (los ntawm 1.0 mm txog 20.0 mm) thiab cov kev xaiv ntev. Ib txwm xa mus rau tus qauv tseem ceeb rau daim ntawv thov - cov kev xav tau tshwj xeeb.

6. Cov kev xav tau ntawm kev txhim kho thiab cov txheej txheem

Kev txhim kho kom zoo yog qhov tseem ceeb rau kev ua haujlwm ntawm JIS B 1360 (SPA1) Spring Pin. Cov kev cai tseem ceeb ntawm kev teeb tsa thiab cov txheej txheem yog raws li hauv qab no:

Qhov Kev Npaj: Lub qhov mating yuav tsum tau drilled rau qhov loj me me (raws li tau teev tseg hauv JIS B 1360) kom ua tiav qhov kev cuam tshuam uas yuav tsum tau ua. Lub qhov taub yuav tsum me ntsis me dua tus pin lub nominal txoj kab uas hla (feem ntau 0.01 hli - 0.05 hli me, nyob ntawm tus pin loj). Lub qhov yuav tsum du (Ra tsawg dua lossis sib npaug li 1.6 μm) kom txo qis kev sib txhuam thaum lub sijhawm teeb tsa thiab tiv thaiv kev puas tsuaj rau tus pin nto.

Cov cuab yeej Installation: Cov cuab yeej kev teeb tsa muaj xws li pin punches, hydraulic lossis pneumatic tus pin inserters, lossis cov cuab yeej xovxwm. Cov cuab yeej yuav tsum tau ua raws li tus pin lub axis kom tsis txhob khoov lossis ua rau tus pin thaum lub sijhawm teeb tsa.

Txheej txheem installation: Ntxig lub chamfered kawg ntawm tus pin rau hauv lub qhov, tom qab ntawd siv lub zog axial kom txog thaum tus pin tau zaum tag nrho (ntxuav nrog rau saum npoo ntawm cov khoom sib dhos los yog raws li daim ntawv thov tsim). Tsis txhob siv lub zog ntau dhau, vim qhov no yuav ua rau tus pin deform mus tas li lossis ua rau lub qhov mating puas.
