Ngaba kuyabiza ukulungisa ibholithi eyaphukileyo kwinqaba yeinjini yomoya? Zama i-A4-80 ye-stainless steel studs

Kwishishini lamandla omoya, ukuthembeka kweebholiti zenqaba kuchaphazela ngokuthe ngqo ukusebenza okukhuselekileyo kunye neendleko zokugcinwa kweyunithi. Intsimbi yekhabhoni yemveli okanye iibholiti zetsimbi eziqhelekileyo ziyakwazi ukudinwa ukuphuka, ukubola kunye nokukhulula phantsi kwemithwalo yomoya yexesha elide kunye neendawo zokungcangcazela, okubangela ukulungiswa rhoqo kunye nokulahlekelwa kokuvelisa amandla. Imigangatho ye-A4-80 ye-stainless steel studs iba sisisombululo esikhethiweyo sokuphucula ukuthembeka kwishishini lamandla omoya ngenxa yeempawu zabo ezintle zoomatshini kunye nokuxhathisa ukubola.

Iindlela zokusilela okuqhelekileyo kweebholiti zamandla omoya

1. Ukuphuka kokukhathala: Inqaba ixhomekeke kwimithwalo eguqukayo ngexesha lokusebenza, kwaye iibholiti zivelisa i-microcracks kwaye zandise phantsi koxinzelelo oluphindaphindiweyo.

2. Ukungaphumeleli okuxekethileyo: Ukungcangcazela kubangela ukuba ukulayisha kwangaphambili kubole, kwaye ukunxitywa kwe-micro-motion kwenzeka kwiindawo zoqhagamshelwano.

3. Ukonakala koxinzelelo: Imekobume yokutshiza ngetyuwa kwiifama zomoya eziselunxwemeni ikhawulezisa ukuqaliswa kokuqhekeka

4. Umngcipheko we-Hydrogen embrittlement: Iinkqubo ezingafanelekanga zonyango lobushushu zingakhokelela ekulibazisekeni ukuphuka

Iingenelo zobuchwephesha ze-A4-80 zebakala ze-stainless steel studs

1. Amandla aphezulu kakhulu: Amandla okuqina asezantsi yi-800MPa, malunga ne-30% ephezulu kunesiqhelo sentsimbi engama-304

2. Ukuqina okugqwesileyo: emva konyango lobushushu lwesisombululo, ubude ≥15%, ukuchasana kwempembelelo entle

3. Ukumelana nokubola: I-316 i-substrate yensimbi engenasici, ukusebenza okugqwesileyo kwindawo yokutshiza ityuwa

4. Ukucutshungulwa kokuchaneka: ukwenza intambo epheleleyo yokuqengqeleka, ukuqinisekisa ukuchaneka komgangatho kunye nomgangatho womphezulu.

Ukuqinisekiswa kwezalathi zobugcisa eziphambili

Uvavanyo lweempawu zoomatshini:

Amandla okuqina: 810-850MPa

Amandla esivuno: ≥640MPa

Ukuqina: HV230-280

Uvavanyo lokutya:

Uvavanyo olungathathi hlangothi lokutshiza ityuwa: iiyure ezingama-2000 ngaphandle komhlwa obomvu

Uvavanyo lwe-corrosion yoxinzelelo: ngokuhambelana nomgangatho we-ISO 3506

Ukusebenza kokudinwa:

Ngaphantsi komlinganiselo womthwalo weminyaka engama-20, ubomi bokudinwa buhlangabezana neemfuno zoyilo

Iingcebiso zokukhetha

Ukuqinisekiswa kwezinto:Funa ababoneleli ukuba babonelele ngesatifikethi sezinto eziphathekayo ukuqinisekisa ukuba umxholo we-Mo ngu-≥2.1%

Inkqubo yokuqinisekisa:

Jonga ukuba ingaba isicombululo sinyangelwe ubushushu

Qinisekisa inkqubo yonyango lwe-surface passivation

Iindawo zokuhlohla:

Sebenzisa indlela ye-engile yetorque ukulawula ukulayisha kwangaphambili

Kunconywa ukusebenzisa kunye ne-anti-loosening gaskets

Iingcebiso zokugcina:

Jonga rhoqo ubume bokulayisha kwangaphambili

Misela ifayile yokutshintsha ibholi

Ukuqinisekiswa kwesicelo seshishini

Ngokwengxelo ye-arhente yovavanyo lomntu wesithathu, phantsi kweemeko ezifanayo zokusebenza:

1. Ubomi benkonzo ye-A4-80 ibakala le-Stainless steel studs ngamaxesha angama-3-5 kuneebhotshi zentsimbi eziqhelekileyo zekhabhoni.

2. Ithuba lokulondoloza linokwandiswa libe ngaphezu kweminyaka emi-5

3. Iindleko ezipheleleyo zomjikelo wobomi zincitshiswa ngaphezu kwe-40%

Silandela ngokungqongqo i-ISO 3506, i-ASTM A4-80 imigangatho yentsimbi engenasici iveliswa ngokwemigangatho yezizwe ngezizwe efana ne-A193, kwaye ibonelela:

1. Gqibezela amaxwebhu esiqinisekiso sezinto eziphathekayo

2. Ingxelo yovavanyo lweepropati zoomatshini

3. Izatifikethi zezatifikethi zomntu wesithathu (ezifana ne-DNV, TUV, njl.)

Ukuba ufuna ulwazi oluneenkcukacha lobugcisa okanye uvavanyo lwesampulu, nceda uzive ukhululekile ukuqhagamshelana nathi.
