Ukumakwa kwamawasha ayisicaba

“Ingabe amawasha ayisicaba adinga ukumakwa?” “Cha?”

“Ingabe bayayidinga?”……

Namuhla sixoxa nawe ngalolu daba, kungenzeka ukuthi abantu abaningi embonini bazocabanga“Xiaowan ah, awunamsebenzi omncane ……”.

Njengoba sonke sazi, ama-washers ayisicaba njengoxhumano lwe-fastener yokufaneleka okubalulekile, ikakhulukazi adlala indima ekwandiseni indawo yokuxhumana, ehlakaza indima yokucindezela kokuxhumana. Iningi lamawasha ayisicaba asetshenziswa ekuhlanganiseni kwezimboni akumakiwe njengale esithombeni esingezansi.

Ngakho-ke yiziphi izimo lapho amawasha ayisicaba azomakwa khona?

(1) Imboni yokukhiqiza ukugwema ukuxuba izinto

Amawasha ayisicaba enqubo yokukhiqiza yokubunjwa kwe-strip stamping emincane, isitshalo sokukhiqiza endaweni yokumaka ye-washa eyisicaba iwukuba kugwenywe ukukhiqizwa kokucaciswa okufanayo kwezinto ezihlukene zamawasha ayisicaba, ekukhiqizeni noma ekuthuthweni kwenqubo yokudideka kwezinto kanye nendlela yokulawula inqubo. Ngokwesibonelo, i“304”emfanekisweni olandelayo, okungukuthi, egameni lewasha eliyisicaba yimpahla engu-A2. Uma umkhiqizi ekhiqiza iwasha eyisicaba enencazelo efanayo ezintweni ezingu-316 ngesikhathi esifanayo, iwasha ingase imakwe“316”or “A4”.

Lesi sibonakaliso sokuhlonza izinto sivamile kuma-washers ayisicaba ensimbi engenasici, isizathu siwukuthi ngemva kokukhiqizwa kwemikhiqizo yensimbi engagqwali ngokuvamile kwenziwa kuphela ngemva kokuhlanza nokudlula, kusukela ekubukeni okumhlophe okukhanyayo, ayikwazi ukuhlukanisa intuitively impahla yayo.

Izinto ezibonakalayo zicacile ebusweni bensimbi engenasici yama-washers flat angagwema ngokuphumelelayo inqubo yokukhiqiza noma yokuhlanganisa yezinto ezixubile.

(2) izinhlinzeko ezijwayelekile

Izindinganiso ezithile zomkhiqizo zicacisa izidingo zamawasha ayisicaba amakwe, isibonelo, izinga“EN”, “EN”, “EN”, “EN”, “EN”futhi“EN”.

Ngokwesibonelo, indinganiso“I-TS EN 14399-5 (GB / T 32076.5) amajoyinti esakhiwo alayishwe ngaphambili anamandla aphezulu Ingxenye 5: Amawasha ayisicaba”kumawasha ayisicaba acishiwe futhi athambile kufanele amakwe nge-concave, njengoba kukhonjisiwe ngezansi:

Ngokwesibonelo, indinganiso“I-ASTM F436 Amawasha Ensimbi Eqinile”icacisa ukuthi amawasha ayisicaba angaphansi kwaleli zinga kufanele amakwe nge“F436”uphawu, njengoba kuboniswe ngezansi:

Amawasha ayisicaba amakwe noma angaphawulwanga ngezinga angasuselwa kuwo?

Uma ubheka izindinganiso zamanje zomkhiqizo, izindinganiso zamawasha ayisicaba ukuthi adlale yini ukumaka akucaciswanga kahle.

I-ISO 898-3: I-2018 ejwayelekile (izakhiwo zemishini yezinsimbi - ama-washers ayisicaba) Izinga liwukuqaliswa kwezidingo zokusebenza ze-carbon steel, i-alloy steel material flat washers ngo-2018, lapho isahluko 9.2 sokumaka iwasha eliyisicaba senze izinhlinzeko ezicacile.

Ukumakwa kwewasha eliyisicaba kungase kube ngokubona komkhiqizi noma ngesivumelwano phakathi kokuhlinzeka nokufunwa.

Amawasha ayisicaba akufanele amakwe ngezinhlamvu eziphakanyisiwe. Ukumakwa kwe-Concave ngokuvamile akunconyiwe ngoba kungashintsha ubudlelwano be-torque-clamping force yejoyinti lebhawudo noma kudale ukugxilisana kwengcindezi okungase kubangele ukuqhekeka kwewasha.

La maphuzu amabili angenhla abonisa ukuthi ukumakwa kwamawasha ayisicaba akuphoqelekile, futhi kukumhlinzeki ukuthi anqume noma axoxisane ngokuthi kuyadingeka yini ukumakwa ngaphambi koku-oda. Akunconywa ukumaka indawo engaphezulu yamawasha ayisicaba anezinhlamvu eziqoshiwe noma ezigobile.

I-Austenitic stainless steel stainless steel flat washer ukumakwa kwe-concave kuzoshintsha ibhawudo - i-nati elixhuma i-vice torque - ubudlelwano be-clamping force kufanele kufakazelwe, kuqinisekile ukuthi, ngenxa yobulukhuni obuphansi bensimbi engagqwali ye-austenitic, ukumaka kwe-concave ngeke kuholele ekugxilweni kwengcindezi ku-washer, ngeke kubangele ukuqhekeka kwewasha.
