I-fastener yokuwela

Masithethe ngefastener yomnqamlezo. Uninzi lwabantu, kwanabanye kurhwebo, ngokukhawuleza bacinga ukuba iPhillips isijija. Leyo yimbono yokuqala ephosakeleyo. Eli gama ngokwenene libandakanya uluhlu olubanzi lweendawo zokuhlala ezilungiselelwe ukuhanjiswa kwetorque kunye nomqhubi onqamlezileyo. IPhillips (PH) luhlobo nje olunye, kunye nePozidriv (PZ) ingomnye umdlali ophambili. Ukubhideka phakathi kwabo mhlawumbi kunoxanduva lwesiqingatha sentloko ye-screw endiyibonile ebaleni. Ubamba umqhubi we-PH2 yesikrufu se-PZ2, sinokuhlala, kodwa uphuma phambi kokuba ufikelele kumthwalo ofanelekileyo, uhlafuna ikhefu. Ngumahluko woyilo olusisiseko, hayi umba womgangatho onesibophelelo ngokwaso.

IAnatomy yeRecess

Ukujonga phantsi kweglasi, ijometri ibalisa ibali. Ikhefu lasePhillips lineendonga ezicekethekileyo kunye neekona ezingqukuva emnqamlezweni. Yenzelwe ukuba iphume phantsi kwetorque engaphezulu-into ekucingelwa ukuba ikhuselekile kwiintambo zendibano ukunqanda ukuqina kunye nokwaphula izinto ezibuthathaka. I-Pozidriv, ephuhliswe kamva, ineendonga ezisecaleni ezithe tye, iimbambo ezongezelelekileyo eziphuma phakathi kweengalo ezinqamlezileyo eziphambili, kunye ne-engile enzulu, engacacanga. Oku kunika uthethathethwano oluhle ngakumbi, kunciphisa i-cam-out, kwaye ivumela usetyenziso lwetorque ephezulu. Iingcebiso zomqhubi azitshintshi ukusebenza ngokugqibeleleyo, ngaphandle kokuba iseti yestolo yehardware yenjongo jikelele inokucebisa.

Ngokwesiqhelo, oku kuthetha ukucacisa uhlobo oluchanekileyo lokuqhuba kubaluleke kakhulu njengokucacisa ibakala okanye imathiriyeli. Kwindlu ye-aluminium yebhokisi ye-telecom yangaphandle, usebenzisa i-stainless steel PZ screw kunye nomqhubi we-PZ ochanekileyo kuthetha ukuba unokufezekisa uxinzelelo oluyimfuneko ngaphandle kokuchitha intloko, nasemva kwemozulu. Sebenzisa umqhubi we-PH, kwaye uya kube ukhupha izikrufu kunyaka wesibini. Ndiyifunde le nto kabuhlungu kwibhetshi yeendawo ezivaliweyo malunga neshumi leminyaka eyadlulayo; sifumene into ebesicinga ukuba zizikrufu zentloko ezinqamlezileyo ukusuka kumboneleli jikelele, sizidibanise nabaqhubi be-PH abasemgangathweni, kwaye saba nenqanaba lokungaphumeleli kwintsimi kwizincamatheliso zephaneli ezaziyintloni. I-post-mortem ibonise umonakalo we-cam-out yakudala kwii-fasteners ezikhethiweyo ze-PZ esizithenge ngokungazi.

Izinto eziphathekayo kunye neplating zidlala kule nto. I-zinc-plated carbon steel fastener cross kwi-recess ye-PH inokwenza ngokufanelekileyo kwi-drywall. Kodwa zama oko ngesikrufu esiqinileyo esingenastainless, kwaye utyekelo lokutyibilika lomqhubi luba yintloko enkulu. Okukhona i-fastener iqina, kokukhona ukukhwelana komqhubi ukuya ku-recess kubaluleke ngakumbi. Kulapho ubona ixabiso kubaboneleli abaqonda ubunjineli, hayi nje imveliso. Ummandla ofana neYongnian eHebei, indawo enkulu yemveliso, ineefektri eziqhuba i-gamut ukusuka kwimveliso ephantsi ukuya kubavelisi abagxile ngokuchanekileyo. Aba bamva bafumana ezi nuances.

Ukufumana kunye neNyaniso yeMigangatho

Okundizisa ekufuneni. Ikhonkco lonikezelo lwehlabathi lonke lizaliswe zizibophelelo ezinqamlezayo ezidibana nomgangatho ofana ne-ISO 7045 okanye 7046, kodwa usathana ukunyamezelelana. I-angle ye-recess, ubunzulu, ubukhali beekona-ezi zinto zihlukanisa i-fastener esebenza kakuhle kumgca wokuvelisa ukusuka kulowo obangela ingxoxo yomqhubi kunye nokukhathala komqhubi. Ndikhe ndandwendwela izityalo apho isitampu sifa ngenxa yekhefu ziqhutywa ngamawaka emijikelo edlulileyo kubomi babo obugqibeleleyo, ukonga nje iindleko zezixhobo. Izibophelelo ezibangelwayo zikhangeleka zilungile kwisampulu yesixa, kodwa ukungaguquguquki kuyadutyulwa.

Kungenxa yoko le nto ukusondela kwisiseko semizi-mveliso esele sikhulile kubalulekile. Umvelisi obekwe kwindawo yemveliso egxininisiweyo, njenge I-Sunnian Zitai Festener Fishaner Comment Com. e Yongnian, Hebei, uhlala enofikelelo olungcono izixhobo ezizodwa kunye neenkonzo zogcino die. Indawo ezikuyo, ezimelene nothungelwano olukhulu olufana neBeijing-Guangzhou Railway kunye ne-expressways, ayiyondawo yokuthengisa nje yokuthumela ngenqanawa; kuthetha ukuba abameli babo bobugcisa kunye nabaphathi bomgangatho banokundwendwela ngokulula iivenkile zezixhobo kunye nezixhobo zokuzoba ngocingo ezondla imveliso yazo. Le nethiwekhi edibeneyo ivumela ulawulo olungqongqo kwi-front-end yenkqubo, echaza umgangatho wefom ye-recess yokugqibela.

Ungakubona oku kwisiza esinje https //wwww.ziitasteners.com. Ngelixa iikhathalogu ezininzi ezikwi-intanethi zidwelisa nje ikhefu okanye iPhillips, iinkcukacha ezineenkcukacha kunye nokwahlula okucacileyo phakathi kweenkqubo ze-PH kunye ne-PZ zicebisa ukuqonda okunzulu kobugcisa. Ibonisa umthengisi obonelela abathengi abafuna indawo efanelekileyo, hayi nje inxalenye etshiphu. Kwinjineli yeprojekthi, nantso indawo yokuqalisa incoko.

Imigibe yeSicelo kunye noLungiso lweNdawo

Ngaphaya kokudityaniswa, ukulungiswa kulapho iziphene ze-fastener ezinqamlezayo zivela khona. Umhlwa, ipeyinti, ubumdaka—zonke zizalise elo khefu lichanekileyo. Ndichithe iiyure ezininzi kwiifowuni zenkonzo apho eyona ngxaki yayingeyonto ingaphumeleliyo, kodwa intloko ye-fastener idliwe okanye ivalekile kangangokuba akukho mqhubi unokuluma. Kwiziseko ezingundoqo ezingundoqo, esi sisiphene soyilo. I-fastener yomnqamlezo, ngakumbi iPhillips, ayilunganga kwindawo enokonakala okuphezulu okanye kwindawo engcangcazelayo apho kuqikelelwa ukwahlukana. Ukudibanisa (umnqamlezo ngesikwere) okanye iTorx ihlala ilukhetho olungcono lobomi, nangona iprimiyamu yeendleko.

Kukho amaqhinga, kunjalo. Ukucoca ikhefu ngokukhetha, usebenzisa umqhubi onempembelelo entsha, ekumgangatho ophezulu, kunye nokusebenzisa i-oyile egqobhozayo kumda wentloko (hayi nje imisonto) inokusebenza imimangaliso. Kodwa ezi zilungiso zentsimi. Esona sisombululo singcono sisicaciso sangaphambili: ukukhetha uhlobo olululo lwedrayivu, i-corosion-resistant corrosion njenge-Geomet okanye i-Dacromet, kunye nokuqinisekisa ukuba abasebenzi bendibano banabaqhubi abachanekileyo, abagcinwe kakuhle. Ivakala isisiseko, kodwa iyothusa ukuba kangaphi olu landelelwano luqhekeka.

Ndikhumbula ukufakela kwifama yelanga apho izibiyeli zikaloliwe ezikhwelayo zisebenzisa izikrufu ze-PZ3 ezingenasici. Unokontraka usebenzise impembelelo yombane ngeebits ezisemgangathweni ze-PH3. Ngethuba umqolo wokuqala uphakanyisiwe, mhlawumbi i-30% yeentloko ze-screw zazibonakala zonakele. Kuye kwafuneka siwumise umsebenzi, sifumane impembelelo ye-PZ3 echanekileyo, kwaye sibuyisele zonke izibophelelo ezisengozini. Ulibaziseko luxabisa ngaphezulu kwe-odolo ye-fastener iyonke. Isifundo ibiyeyokuba i-fastener specication sheet ayinamsebenzi ukuba ayifikeleli ezandleni ezijika izixhobo.

Ikamva le-Cross Drive

Ingaba isiqhoboshi sesiphambano siyaphelelwa? Hayi akunjalo. Kuluhlu oluninzi lwezicelo, ngakumbi kwiplanga, icwecwe lesinyithi elikhanyayo, kunye neeplastiki, ukusebenza kakuhle kweendleko kunye nokulula akunakoyiswa. Inkqubo ye-Phillips's cam-out feature, ehlala inyeliswa ziinjineli, luncedo kwi-automated assembly ye-electronics yabathengi okanye ifenitshala apho ubukhulu bezinto buyahluka. Ithintela ukutyumza. Undoqo kukusebenzisa ngabom.

Iidrive ezintsha ze-hybrid ezifana nePhillips / Square combo zifumana umhlaba, zinika isantya sokulungelelaniswa komnqamlezo kunye ne-torque efanelekileyo yesikwere drive. Kodwa zifuna amasuntswana akhethekileyo. Kumacandelo amaninzi emveliso enomthamo omkhulu, angabizi kakhulu, isiqhoboshi esinqamlezayo, esiveliswe ngokufanelekileyo kwiindawo ezinkulu ezifana neYongnian, iya kuhlala iyinkosi. I-evolution ingaphezulu malunga nesayensi yezinto-zomelele, i-alloys ekhaphukhaphu-kunye neeplatings eziphuculweyo zokwandisa ubomi benkonzo, kunokulahlwa kwi-wholesale ye-recess form.

Kwinkampani yokuvelisa emiliselwe kuloo nkqubo yendalo, umceli mngeni kukulinganisa umthamo wemveliso kunye nemfuno ekhulayo yobungcali. Ayikokwenza nje izikrufu zePhillips eziyibhiliyoni. Imalunga nokuba namandla okuqhuba ibhetshi yezikrufu ze-PZ2 kwi-A4-80 engenabala ene-oxide ethile egqunyiweyo kumthengisi weemoto waseYurophu, kwaye emva koko utshintshele kwi-PH1 yezikrufu zobhedu kwizikhonkwane zombane. Ukuba bhetyebhetye kubuchwephesha beziqhoboshi yeyona nto yokwenyani yokhuphiswano ngoku.

Ukuqukumbela Ngaphandle Kwesaphetha

Ngoko, i-fastener yomnqamlezo. Lisuntswana lejometri eyenziwe ngobunjineli ebambe umhlaba wanamhlanje kunye, kodwa ihlala iyinto ecingelwayo. Ukusebenza kwayo kuxhomekeke kunxibelelwano olufihlakeleyo phakathi koyilo lwekhefu, umgangatho webit yomqhubi, ulwazi lomsebenzisi, kunye nokusingqongileyo kwesicelo. Ukunyanga zonke iidrives ezinqamlezayo ngokufanayo yindlela ekhawulezayo yokuhlanganisa intloko kunye nokusilela kwintsimi.

Ukusetyenziswa okuyimpumelelo kuhla ekuhlonipheni iinkcukacha zayo. Cacisa Pozidriv xa ufuna torque ngaphandle cam-out. Cacisa iiPhillips xa ufuna isiliphu esilawulwayo. Qinisekisa ukuba isixokelelwano sonikezelo, ukusuka kumenzi ukuya kwisingxobo sesixhobo somfaki, siyawuhlonipha lo mahluko. Kwaye xa ukhangela, qwalasela isiseko esisemva komboneleli-inkampani esembindini wesithili saseTshayina, njengale ikhankanywe ngaphambili, ihlala inenzuzo ebonakalayo yokungaguquguquki kunye nokubamba kobugcisa ngokuchanekileyo kuba ingqongwe yinkqubo yendalo yonke yeshishini.

Ekugqibeleni, licandelo elifuna ukuhoywa ngakumbi kunokuba liqhele ukufumana. Ukuyilungisa akubonakali. Ukuyenza ingalunganga imisa imigca yemveliso, icaphukisa amagcisa, kwaye ibeka esichengeni iimveliso. Obo bubunzima bokwenyani umnqamlezo olula ofanele ukuthwala.
