Chizindikiro cha ma washers ophwatsuka

"Kodi ma washer a flat amayenera kulembedwa?" “Ayi?”

“Kodi amachifuna?”………

Lero tikambirana nkhaniyi ndi inu, mwina anthu ambiri mu makampani angaganize“Xiaowan ah, ndiwe wopanda ntchito pang'ono ……”.

Monga ife tonse tikudziwa, lathyathyathya washers monga cholumikizira cholumikizira chofunika koyenera, makamaka ntchito kuonjezera kukhudzana m'dera, dibalalitsa udindo kukhudzana kuthamanga. Ma washers ambiri omwe amagwiritsidwa ntchito m'mafakitale sakudziwika ngati omwe ali pachithunzichi.

Ndiye ndizochitika zotani zomwe ma washers ophwatsuka azilembedwa?

(1) Chomera chopangira kupewa kusakaniza zinthu

Lathyathyathya washers kupanga ndondomeko yopapatiza Mzere chidindo akamaumba, kupanga chomera mu lathyathyathya makina ochapira pamwamba chodetsa ndi pofuna kupewa kupanga specifications osiyana zipangizo lathyathyathya washers, mu kupanga kapena podutsa ndondomeko chisokonezo zinthu ndi njira kulamulira ndondomeko. Mwachitsanzo, a“304”mu chithunzi chotsatirachi, ndiye kuti, m'malo mwa chochapira chathyathyathya ndi zinthu za A2. Ngati wopanga apanga makina ochapira athyathyathya amtundu womwewo muzinthu 316 nthawi imodzi, ndiye kuti chochapiracho chikhoza kulembedwa“316”or “A4”.

Chizindikiro ichi cha chizindikiritso cha zinthu ndi wamba mu zosapanga dzimbiri zitsulo lathyathyathya washers, chifukwa ndi kuti pambuyo kupanga mankhwala zosapanga dzimbiri zitsulo zambiri zimangochitika pambuyo kuyeretsa ndi passivation, kuchokera maonekedwe oyera owala, sangathe intuitively kusiyanitsa zinthu zake.

Zinthuzo zimamveka bwino pamtunda wazitsulo zosapanga dzimbiri zosapanga dzimbiri zimatha kupewa kupanga kapena kusonkhana kwa zipangizo zosakanikirana.

(2) makonzedwe oyenera

Miyezo ina yamankhwala imatchula zofunikira za ma washers athyathyathya okhala ndi chizindikiro, mwachitsanzo, muyezo“EN”, “EN”, “EN”, “EN”, “EN”ndi“EN”.

Mwachitsanzo, muyezo“TS EN 14399-5 (GB / T 32076.5) zolumikizira zomangidwa mwamphamvu kwambiri - Gawo 5: ma washer”muzitsulo zozimitsidwa ndi zowonongeka ziyenera kulembedwa ndi concave, monga momwe zilili pansipa:

Mwachitsanzo, muyezo“Makina Ochapira Azitsulo a ASTM F436”imanena kuti ma washer ophwatsuka omwe amatsatira mulingo uwu ayenera kukhala ndi chizindikiro“F436”chizindikiro, monga pansipa:

Makina ochapira athyathyathya olembedwa kapena osasindikizidwa ndi muyezo angakhazikitsidwe?

Kuyang'ana pamiyezo yomwe ilipo masiku ano, miyezo ya ma washers athyathyathya kaya azisewera chizindikiro sichimafotokozedwa bwino.

Muyezo wa ISO 898-3: 2018 (mawotchi opangira zomangira - ma washers ophwanyika) Muyezo ndikukhazikitsa zofunikira pakuchita kwa carbon steel, alloy steel material flat washers mu 2018, pomwe mutu 9.2 wa cholembera chalathyathyathya wachapira bwino.

Cholemba chachabechabe chathyathyathya chikhoza kukhala pakufuna kwa wopanga kapena mwa mgwirizano pakati pa kupezeka ndi kufuna.

Makina ochapira a Flat sayenera kulembedwa zilembo zokwezeka. Kuyika chizindikiro kwa concave nthawi zambiri sikuvomerezeka chifukwa kumatha kusintha kulumikizana kwamphamvu ya bolt-nati kapena kupangitsa kupsinjika komwe kungayambitse kusweka kwa chochapira.

Mfundo ziwiri zomwe zili pamwambazi zikuwonetsa kuti kuyika chizindikiro kwa ma washers athyathyathya sikofunikira, ndipo zili kwa wogulitsa kuti asankhe kapena kukambirana ngati kuyika chizindikiro kumafunikira musanayitanitsa. Sitikulimbikitsidwa kuyika chizindikiro pamwamba pa ma washers athyathyathya okhala ndi embossed kapena concave zilembo.

Austenitic stainless steel flat washer pamwamba pa concave marking isintha bawuti - nati yolumikizira vice torque - mgwirizano wamphamvu uyenera kutsimikiziridwa, ndizotsimikizika kuti, chifukwa cha kulimba kwachitsulo chosapanga dzimbiri cha austenitic, kuyika chizindikiro kwa concave sikungabweretse kupsinjika mu chochapira, sikuyambitsa kusweka kwa chochapira.
