Ukuphawula ii-washers ezisicaba

“Ingaba kufuneka kuphawulwe ii-washers ezisicaba?” “Hayi?”

“Ngaba bayayidinga?"……

Namhlanje siza kuxoxa ngale ngxaki nawe, mhlawumbi abantu abaninzi kweli shishini baza kucinga njalo.“Xiaowan ah, awungomsebenzi kangako ……".

Njengoko sonke sisazi, ii-washers ezisicaba njengesixhobo sokudibanisa izinto ezifunekayo, zidlala indima enkulu ekwandiseni indawo yoqhagamshelwano, zisasaza indima yoxinzelelo loqhagamshelwano. Uninzi lwee-washers ezisicaba ezisetyenziswa kwindibano yemizi-mveliso aziphawulwanga njengale ikumfanekiso ongezantsi.

Ngoko ke zeziphi iimeko apho kuya kubekwa uphawu khona ii-washers ezisicaba?

(1) Isityalo semveliso ukuze kuthintelwe ukuxuba izinto

Ii-washers ezisicaba zenkqubo yokuvelisa i-strip stamping molding, isityalo semveliso kumphezulu we-washer osicaba siphawula ukuze kuthintelwe ukuveliswa kweenkcukacha ezifanayo zezinto ezahlukeneyo, kwinkqubo yokuvelisa okanye yokudlulisa izinto ezididayo kunye nendlela yokulawula inkqubo. Umzekelo,“304"kumfanekiso olandelayo, oko kukuthi, egameni le-flat washer kukho izinto ze-A2. Ukuba umenzi uvelisa i-flat washer eneempawu ezifanayo kwizinto ze-316 ngaxeshanye, i-washer inokuphawulwa ngolu hlobo.“316"or “A4".

Olu phawu lokuchongwa kwezinto luqhelekile kwii-washers zentsimbi engagqwaliyo, isizathu kukuba emva kokuveliswa kweemveliso zentsimbi engagqwaliyo ngokubanzi zenziwa kuphela emva kokucoca kunye nokungasebenzi, ukusuka kwimbonakalo yomhlophe oqaqambileyo, abakwazi ukwahlula izinto zayo ngokwemvelo.

Izinto ezisetyenzisiweyo zicacile kumphezulu wee-washers zentsimbi engagqwaliyo zinokuyiphepha ngempumelelo inkqubo yokuvelisa okanye yokuhlanganisa izinto ezixutyiweyo.

(2) amalungiselelo asemgangathweni

Imigangatho ethile yemveliso ichaza iimfuno zee-washers ezisicaba eziphawulwe, umzekelo, umgangatho“EN", “EN", “EN", “EN", “EN"kwaye“EN".

Umzekelo, umgangatho“I-EN 14399-5 (GB / T 32076.5) ii-bolts zokwakha ezifakwe kwangaphambili ezinamandla aphezulu ezifakwe kwi-Icandelo 5: ii-washers ezisicaba"Kwizihlambi ezicociweyo nezithambileyo, kufuneka ziphawulwe nge-concave, njengoko kubonisiwe ngezantsi:

Umzekelo, umgangatho“IiWasher zeNsimbi eziQinisiweyo ze-ASTM F436"icacisa ukuba ii-washers ezisicaba eziphantsi kwalo mgangatho kufuneka ziphawulwe ngolu hlobo“F436"uphawu, njengoko kubonisiwe ngezantsi:

Ii-washers ezisicaba eziphawulwe okanye ezingaphawulwanga ngomgangatho zinokusekelwa kuzo?

Xa sijonga imigangatho yemveliso yangoku, imigangatho yabahlambi abasicaba ukuba badlale uphawu lokuba badlale na ayichazwanga ngokucacileyo.

I-ISO 898-3 esemgangathweni: 2018 (iimpawu zoomatshini zezibophelelo - ii-washers ezisicaba) Umgangatho kukuphunyezwa kweemfuno zokusebenza kwee-washers ezisicaba zentsimbi yekhabhoni, intsimbi ye-alloy ngo-2018, apho isahluko 9.2 sokumakishwa kwe-washer esisicaba senza amalungiselelo acacileyo.

Ukuphawula i-flat washer kungenziwa ngokwesigqibo somenzi okanye ngokwesivumelwano phakathi kokubonelela kunye nemfuno.

Iiwasher ezisicaba azifanele ziphawulwe ngoonobumba abaphakanyisiweyo. Ukumakishwa okugobileyo akukhuthazwa kuba kunokutshintsha ulwalamano lwamandla okubamba i-torque kwijoyinti ye-bolt-nut okanye kudale uxinzelelo olunokubangela ukuqhekeka kwewasher.

Ezi ngongoma zimbini zingentla zibonisa ukuba ukuphawulwa kwee-flat washers akunyanzelekanga, kwaye kuxhomekeke kumthengisi ukuba agqibe okanye axoxisane nokuba kuyimfuneko na ukuphawulwa ngaphambi kokuba aodole. Akukhuthazwa ukuba uphawulwe umphezulu wee-flat washers ngoonobumba abatyhidiweyo okanye abagobileyo.

Uphawu lwe-Austenitic stainless steel flat washer surface concave marking luya kutshintsha i-bolt – nut connecting vice torque – ubudlelwane bamandla okubamba kufuneka buqinisekiswe, ngokuqinisekileyo ukuba, ngenxa yobunzima obuphantsi be-austenitic stainless steel, uphawu lwe-concave aluyi kukhokelela ekuxinaniseni koxinzelelo kwi-washer, aluyi kubangela ukuqhekeka kwe-washer.
