Kufuneka-ufundelwe ukusetyenzwa kwesinyithi: Ungakhetha njani izikrufu zokuzicofa? Izakhono ezisebenzayo zokuthintela ukuqhekeka kunye nokuhluba

Kwi-sheet metal processing, i-self-tapping screws yenye yezona zinto zisetyenziswa ngokuqhelekileyo izibophelelo, kodwa ukhetho olungafanelekanga lunokubangela ukuqhekeka, ukuhluthwa, ukukhulula kunye nezinye iingxaki, ezichaphazela amandla emveliso kunye nokusebenza kakuhle kwendibano. Unokukhetha njani izikrufu ezifanelekileyo zokuzicofa ngokusekwe kubukhulu bezinto eziphathekayo, iimfuno zomthwalo, kunye nezinto zokusingqongileyo? Eli nqaku liza kwabelana ngezinto eziphambili zokukhetha kunye neengcebiso ezichasene nokusilela ukukunceda wenze izisombululo zokubopha intsimbi.

1.Imiba emine ePhambili ekuKhethweni kweZikruphu zokuZimbela

Iphepha lezinto zetsimbi kunye nobunzima

Iintsimbi ezahlukeneyo (ezifana neepleyiti zentsimbi eziqengqelekayo ezibandayo, intsimbi engatyiwa, kunye neepleyiti zealuminiyam) zinomehluko omkhulu kubulukhuni, obuchaphazela ngqo isakhono sokungena kwezikrufu ezizibambayo:

Izinto ezithambileyo (i-aluminiyam, ubhedu):ilungele izikrufu zomsonto wokunciphisa umngcipheko wokuguqulwa kwezinto.

Izinto eziqinileyo (intsimbi engatyiwa, iipleyiti zentsimbi ezishinyeneyo):iintambo ezirhabaxa okanye i-drill tails (izikrufu ze-TEK) ziyafuneka ukuze kuqinisekiswe ukungena kakuhle.

Ukuthelekisa ubukhulu bepleyiti kunye nobude bezikrufu

Ubude be-Screw = ubukhulu bepleyiti + 2 ~ 3 amaxesha e-pitch (ukuqinisekisa ukubandakanyeka okupheleleyo kunye nokuphepha ukuhluba).

Imfutshane kakhulu:ukungonelanga umsonto, kulula ukuwukhulula; nde kakhulu: inokungena okanye iphazamise ulwakhiwo lwangaphakathi.

Uhlobo lwentloko kunye nendlela yokuhlanganisa

I-Pan intloko/intloko yekhawunta:isetyenziswe kwiindawo ezineemfuno eziphezulu zokuthe tyaba komphezulu.

Intloko enehexagonal/intloko yeflange:ibonelela ngetorque ephezulu kunye nesiphumo esihle sokuchasa ukukhulula.

Umsila wokuzibhora (TEK):zilungele iipleyiti ezityebileyo, akukho kugrunjwa kwangaphambili, kunye nokusebenza kakuhle.

Unyango lomphezulu kunye nokulungelelaniswa kokusingqongileyo

Iigalvanized:i-anti-rust jikelele, ilungele iindawo zangaphakathi.

I-Dacromet / insimbi engenasici:ukumelana nomhlwa, ilungele indawo ezingaphandle okanye ezifumileyo.

2.Izakhono ezintathu ezisebenzayo zokuthintela ukuqhekeka kunye nokuhluba

Ukombiwa kwangaphambili (kwimathiriyeli yobulukhuni obuphezulu)

Kwintsimbi engenasici okanye iipleyiti zetsimbi ezishinyeneyo, unokuqala ngokugrumba umngxuma wokulinga (umngxuma ububanzi ≈ 70% ye-screw core diameter) ukunciphisa ukunyanzeliswa kokungena kunye nokunciphisa umngcipheko wokuqhekeka.

Lawula ukuqinisa itorque

Itorque egqithisileyo:kubangela ukuguqulwa kwezinto okanye ukutyibilika kwentambo.

Itorque enganelanga:ukudibana okuxekethileyo kwaye kulula ukukhulula.

Kunconywa ukusebenzisa i-screwdriver ye-torque, ngokubhekiselele kwixabiso eliqhelekileyo elinikezwa ngumenzi.

Khetha uyilo oluchasene nokukhulula

Ngewasha zenayiloni:ukwandisa ukukhuhla kwaye uthintele ukungcangcazela.

Uyilo lwemisonto ephindwe kabini:ukuphucula amandla e-meshing, alungele iimeko zomthwalo oguqukayo.

3. Imibuzo Ebuzwa Rhoqo (Q&A)

Umbuzo: I-self-tapping screws kulula ukutyibilika kwiipleyiti ezincinci. Indlela yokusombulula ngayo?

A: Sebenzisa izikrufu zomsonto ocolekileyo okanye izikrufu zokuzicofa ezinamacala okusika ukuphucula amandla okuluma intambo.

Umbuzo: Izikrufu eziqhelekileyo zokuzibamba zilula ukuziqhekeza kwiipleyiti zensimbi ezingenasici. Ndingenza ntoni?

A: Khetha i-304 okanye i-316 ye-screws yensimbi engenasici kunye ne-pre-drill imingxuma encinci ukunciphisa uxinzelelo lokungena.

Q: Ukuqhawulwa rhoqo kunye nokuhlanganisana kukhokelela ekungaphumeleli kwentambo. Ziziphi ezinye iindlela?

A: Sebenzisa i-rivet nuts (i-Rivnut) okanye imikhono enemikhono ukuqinisa ukuqina.

Isishwankathelo

Ukukhethwa kwezikrini zokuzibamba kufuneka kuqwalaselwe ngokubanzi izinto eziphathekayo, ubukhulu beplate, umthwalo kunye nokusingqongileyo, ngokufanelekileyo ukufanisa uhlobo lwentloko kunye nokuphathwa kwendawo, kunye nokulawula inkqubo yokuqinisa ukuphepha iingxaki ezifana nokuqhawula kunye nokuqhawula. Kwiimeko ezikhethekileyo zokusebenza (ezifana ne-vibration ephezulu kunye nokusingqongileyo), i-anti-loosening okanye i-corrosion-resistant model model ingakhethwa, okanye idibaniswe ne-pre-drilling kunye ne-thread reinforcement technology ukuze kulungiswe isisombululo.
