Ukumakishwa kweewasha eziflethi

"Ingaba iiwasha eziflethi kufuneka ziphawulwe?" "Hayi?"

“Ngaba bayayidinga?”……

Namhlanje sixoxa ngalo mbandela nawe, inokuba baninzi abantu abakushishino baya kucinga“U-Xiaowan ah, awunamsebenzi omncinci ……”.

Njengoko sonke siyazi, i-washers flat njengendlela yokudibanisa i-fastener ye-fit fit, ikakhulukazi idlala indima ekwandiseni indawo yoqhagamshelwano, isasaza indima yoxinzelelo loqhagamshelwano. Uninzi lweewasha ezisicaba ezisetyenziswa kwindibano yoshishino aziphawulwanga njengale ikumfanekiso ungezantsi.

Ngoko ke zeziphi iimeko apho iiwasha eziflethi ziya kumakishwa?

(1) Isityalo sokuvelisa ukuphepha ukuxuba izinto

Iiwasha ezisicaba zenkqubo yokuvelisa umcu omxinwa wokunyathela ukubumba, isityalo semveliso kwindawo yokumakisha iwasha tyaba kusenzelwa ukuphepha ukuveliswa kwezinto ezifanayo zezixhobo ezahlukeneyo zokuhlamba iiwasha, kwimveliso okanye inkqubo yokuthutha ukubhideka kwezinto kunye nendlela yokulawula inkqubo. Umzekelo, i“304”kulo mfanekiso ulandelayo, oko kukuthi, egameni lewasha yeflethi yimpahla ye-A2. Ukuba umenzi uvelisa iwasha eflethi yohlobo olufanayo kwizinto ezingama-316 ngaxeshanye, iwasha leyo inokumakishwa“316”or “A4”.

Olu phawu lokuchongwa kwezinto luqhelekileyo kwiiwashi zensimbi ezingenasici, isizathu kukuba emva kokuveliswa kweemveliso zensimbi ezingenasici ngokuqhelekileyo zenziwe kuphela emva kokucoca kunye nokugqithisa, ukusuka ekubonakaleni komhlophe oqaqambileyo, awukwazi ukwahlula intuitively izinto zayo.

Izinto eziphathekayo zicacile kumphezulu we-stainless steel flat washers zinokuphepha ngokufanelekileyo ukuveliswa okanye inkqubo yokuhlanganisa izinto ezixutywe.

(2) amalungiselelo asemgangathweni

Imigangatho ethile yeemveliso icacisa iimfuno zeewasha ezizicaba eziphawulweyo, umzekelo, umgangatho“EN”, “EN”, “EN”, “EN”, “EN”kwaye“EN”.

Umzekelo, umgangatho“I-EN 14399-5 (i-GB / T 32076.5) idityanisiwe yesakhiwo esinebhowudi ephezulu efakwe ngaphambili, icandelo 5: iiwasha ezicaba”kwiiwasha ezicinyiweyo nezipholileyo kufuneka ziphawulwe nge-concave, njengoko kubonisiwe ngezantsi:

Umzekelo, umgangatho“I-ASTM F436 iiWasher zentsimbi eziQinisiweyo”icacisa ukuba iiwasha eziflethi eziphantsi kwalo mgangatho kufuneka ziphawulwe nge“F436”isimboli, njengoko kubonisiwe ngezantsi:

Iiwasha ezizicaba eziphawulweyo okanye ezingaphawulwanga ngomgangatho zinokusekelwa?

Ukujonga kwimigangatho yemveliso yangoku, imigangatho yeewasha eziflethi ukuba zidlala ukumakishwa akuchazwanga ngokucacileyo.

Umgangatho we-ISO 898-3: 2018 (iipropati ze-mechanical of fasteners - i-flat washers) Umgangatho kukuphunyezwa kweemfuno zokusebenza kwe-carbon steel, i-alloy steel material flat washers kwi-2018, apho isahluko 9.2 sokumakishwa kwe-flat washer senze amalungiselelo acacileyo.

Ukumakishwa kwewasha eflethi kusenokuba ngokokubona komvelisi okanye ngokwesivumelwano phakathi konikezelo kunye nemfuno.

Izixhobo zokuhlamba ezineflethi aziyi kuphawulwa ngoonobumba abanyusiweyo. Ukumakishwa kweConcave ngokuqhelekileyo akukhuthazwa kuba kunokutshintsha ubudlelwane be-torque-clamping force ye-bolt-nut joint okanye ukudala uxinzelelo olunokubangela ukuqhekeka kwewasha.

La manqaku mabini angasentla abonisa ukuba ukumakishwa kweewasha eziflethi akunyanzelekanga, kwaye kuxhomekeke kumthengisi ukwenza isigqibo okanye uthetha-thethwano malunga nokuba kufuneka ukumakishwa phambi koku-odola. Akukhuthazwa ukuba uphawule umphezulu we-washers flat nge-embossed okanye i-concave characters.

I-Austenitic stainless steel stainless washer surface concave marking iya kutshintsha i-bolt - i-nut edibanisa i-vice torque - i-clamping force relationship kufuneka ibonakaliswe, ngokuqinisekileyo, ngenxa yobunzima obuphantsi be-austenitic stainless steel, ukumakishwa kwe-concave akuyi kukhokelela ekugxininiseni uxinzelelo kwi-washer, akuyi kubangela ukuqhekeka kwewasha.
