Uhlobo olwahlukileyo lwebholti
Umahluko phakathi kweebholiti nezikrufu ulele kwiinkalo ezimbini: enye yimilo, inxalenye yestud yebholiti ifuneka ngokungqongqo ukuba ibe silinda, isetyenziselwe ukufaka i-nut, kodwa inxalenye yestud yesikrufu ngamanye amaxesha i-conical okanye inencam; enye isebenzisa umsebenzi, isikrufu sifakwa kwisikrufu kwizinto ekujoliswe kuzo endaweni ye-nut. Kwizihlandlo ezininzi, ii-boliti nazo zisebenza ngokwahlukeneyo, kwaye zifakwa ngqo kwisikrufu kumngxuma osele ugrunjiwe, ngaphandle kwemfuneko ye-nut yokusebenzisana nayo. Ngeli xesha, i-boliti ihlelwa njenge-screw ngokwemisebenzi.
Imilo kunye nenjongo yentloko yebholiti zahlulwe zaba ziibholiti zentloko ezineehexagonal, iibholiti zentloko ezisikwere, iibholiti zentloko ezisisiqingatha, iibholiti zentloko ezifakwe ecaleni, iibholiti ezinemingxuma, iibholiti zentloko ezi-T, iibholiti zentloko yehoki (isiseko) njalo njalo.
Umsonto wekholam ungahlulwa ube ngumsonto orhabaxa, umsonto ocolekileyo kunye nomsonto we-intshi, ngoko ke ubizwa ngokuba yi-fine bolt kunye ne-intshi bolt.
Inkqubo yeMveliso
Okokuqala, isithonga sokuqala siyashukuma ukulungiselela ucingo ukuba lwenziwe, size ke isithonga sesibini sishukume ukuze siphinde sibumbe ucingo size sibumbe imveliso egqityiweyo. Kwinkqubo yokubanda, isithonga esisisigxina (i-compression die) kunye nesithonga (i-flattening) ziyashukuma (i-punching)
Inani leentloko alifani. Ezinye izikrufu ezintsonkothileyo zinokufuna iipunch ezininzi ukuze zenziwe kunye, nto leyo efuna izixhobo zezikhululo ezininzi ukuze kwenziwe isikrufu. Emva kokunyakaza kwesikrufu, intloko yesikrufu igqityiwe, kodwa inxalenye yeshaft yesikrufu ayikafakwa ntambo. Indlela yokwenza umsonto wesikrufu kukuqengqeleka komsonto. Ukuqengqeleka komsonto kukusebenzisa ii-die ezimbini ezijikelezayo (iipleyiti zokuhlikihla) ezineentambo ezinamazinyo ukuze kucinezelwe isithuba esingenamisonto esenziwe yi-amulti-station okanye umatshini wokukhokela phakathi.
Emva kokusebenzisa intloko nokuhlikihla amazinyo, isikrufu sonke siye senziwa. Kakade ke, ukuze ukubonakala kwesikrufu kube mhlophe nangcono, inkqubo yokunyanga umphezulu wento idla ngokwenziwa. Njengokucoca nokuthambisa izikrufu zentsimbi engagqwaliyo, ukufakelwa i-electroplating kumphezulu wezikrufu zentsimbi yekhabhoni, njl. Zenziwe ngemibala eyahlukeneyo yezikrufu.
Izixhobo zokufaka iipayipi zizinto ezibalulekileyo kwinkqubo yokuhambisa iipayipi, ezisetyenziselwa ukunxibelelana, ukuqondisa kwenye indawo, ukuphambukisa, ukutshintsha ubungakanani, ukuvala okanye ukulawula ukuhamba kwamanzi. Zisetyenziswa kakhulu kwiindawo ezifana nokwakha, ishishini, amandla kunye neenkonzo zikamasipala.
Imisebenzi ephambili:Ingenza imisebenzi efana nokudibanisa imibhobho, ukutshintsha indlela yokuhamba kwayo, ukwahlula nokudibanisa ukuhamba kwayo, ukulungisa ububanzi bemibhobho, ukuvala imibhobho, ukulawula nokulawula.
Ububanzi besicelo:
- Ulwakhiwo lwamanzi kunye nemibhobho yamanzi:Iingqiniba zePVC kunye nee-PPR tris zisetyenziselwa iinethiwekhi zemibhobho yamanzi.
- Imibhobho yemizi-mveliso:Iiflange zentsimbi engenasici kunye neengqiniba zentsimbi ye-alloy zisetyenziselwa ukuthutha izixhobo zamakhemikhali.
- Uthutho lwamandla:Izixhobo zokufaka iipayipi zentsimbi ezinoxinzelelo oluphezulu zisetyenziswa kwimibhobho yeoyile negesi.
- I-HVAC (Ukufudumeza, Ukungenisa umoya, kunye ne-Air Conditioning):Izixhobo zombhobho wekopolo zisetyenziselwa ukudibanisa imibhobho yefriji, kwaye amalungu aguquguqukayo asetyenziselwa ukunciphisa ukungcangcazela.
- Ukunkcenkceshela kwezolimo:Izihlanganisi ezikhawulezayo zenza kube lula ukuhlanganiswa nokuqhekeka kweenkqubo zokunkcenkceshela izitshizi.
