Masithethe ngesiqhoboshi sesiqingatha. Ngomnye waloo magama anokubangela ukudideka kumgangatho wevenkile okanye kwiphepha elithile. Ayibhekiseli kwisiqhoboshi esisikwe phakathi. Endaweni yoko, sisishunqulelo soshishino kuqwalaselo oluthile, oluhlala lungekho semgangathweni, olungaphelelanga. Ungayiva ibizwa ngokuba yi-half-thread bolt okanye i-bolt yegxalaba kwezinye iimeko, kodwa ingcamango engundoqo yi-shank ebandakanyeka kuphela ngeentambo, ishiya icandelo eligudileyo, elingafundwanga. Ukungaqondi kudla ngokuqala apho-ucinga ukuba yibhawudi nje eqhelekileyo enomsonto omncinci. Ayiyo. Injongo yoyilo yinto yonke.

Apho isiqingatha sibalulekile

Ngokwesiqhelo, ubude bokubambelela obungafundwanga okanye igxalaba luphawu olubalulekileyo. Umsebenzi wayo ophambili kukuthwala imithwalo yokucheba kunye nokubonelela ngolungelelwaniso oluchanekileyo. Xa uthungela ibholiti enemisonto epheleleyo ngeepleyiti ezimbini kwaye uyiqinise, imisonto ibandakanya zombini iziqwenga. Oko kunokukhokelela kwimiba ngokulungelelanisa phantsi koxinzelelo lwecala-imicu inokusebenza njengefayile, ukwazisa umdlalo. A isiqhoboshi sesiqingatha Isombulula oku ngokuthi i-shank yayo egudileyo ilingane kakuhle kumngxunya wokucofa kwiqhekeza elingaphandle, ithatha i-chear, ngelixa isahlulo esiphothiweyo sibandakanya kuphela i-nut okanye umngxuma ocofayo kwiqhekeza elingaphakathi. I-clamping force ilawulwa ngakumbi, kwaye i-joint iqina ngakumbi ngokuchasene nentshukumo esecaleni.

Ndikhumbula iprojekthi kwiminyaka eyadlulayo ebandakanya isakhelo sokuhambisa esingcangcazelayo. Ekuqaleni sasebenzisa iibholiti eziqhelekileyo ze-hex. Ukushukuma rhoqo akuzange kubakhulule; yasonga imingxuma kuba imisonto ibihlafuna umngxuma wokuvula. Ukutshintshela ku-a isiqhoboshi sesiqingatha uyilo, apho i-shank egudileyo yazalisa umngxuma kwaye yathatha i-shear, yamisa ukunxiba ngokupheleleyo. Ukusilela yayiyimeko eqhelekileyo yokusebenzisa isiqhoboshi somsebenzi obungawulelwanga. Isifundo yayikukuba intambo ayisoloko ingumhlobo wakho.

Apha kulapho imathiriyeli kunye neenkcazo zokugqiba zibaluleka khona. Elo shank ligudileyo lihlala lifuna ukunyamezelana kwedayamitha engqongqo kunebholiti eqhelekileyo. Ukuba ikhululekile kakhulu, ulahlekelwa yinzuzo yokulungelelanisa; kuxinene kakhulu, kwaye ukuhlanganisana kuba liphupha elibi. Ukuxhathisa umhlwa, unokubona yonke indawo eshushu-dip ifakwe igalvanized, kodwa ke ubeka umngcipheko wokugalela umsonto. Ngamanye amaxesha, kungcono ukuba ube nemisonto esongwayo emva kokubekwa, okanye ukucacisa ukugqitywa okwahlukileyo kweshank xa kuthelekiswa nemisonto. Zezi nkcukacha zincinci ezahlula into yekhathalogu kwicandelo elisebenzayo.

Ukufumana kunye neTrap eyaneleyo

Apha kulapho izinto ziba yinyani. Awuyi kusoloko ufumana uqwalaselo oluchanekileyo lwesiqingatha somsonto oludingayo kwi-DIN eqhelekileyo okanye kwincwadi ye-ANSI. Uhlala ujonga into eqhelekileyo okanye ephakathi. Isihendo kukuthatha ibholiti enemisonto epheleleyo kwaye ungayithululi yonke indlela, kodwa oko kuqhelekile ukuthomalalisa. Utshintsho ukusuka kwi-shank ukuya kwintambo kwinjongo eyenziwe isiqhoboshi sesiqingatha icocekile, idla ngokuba nomsonto okhululekileyo ophumayo, nto leyo enciphisa uxinzelelo loxinzelelo.

Ndikhe ndajongana nabanikezeli abathembisa ibolt yesiqingatha somsonto kuphela ukuhambisa ibholithi eqhelekileyo enecandelo elingaphantsi okanye elingakhiwanga kakuhle elingafundwanga. Umgangatho we-roll-forming kwi-threaded section kunye nokuthe tye kwe-shank kukuxelela ngokukhawuleza. I-shank egobileyo kwinxalenye elungiselelwe ukulungelelaniswa ngokuchanekileyo ayinamsebenzi. Yiyo loo nto ukufumana umenzi onobuchwephesha bolungelelwaniso olungekho mgangathweni ngundoqo. Ngokomzekelo, inkampani efana I-Sunnian Zitai Festener Fishaner Comment Com., esekwe kwisiseko semveliso yenxalenye enkulu yaseTshayina eYongnian, ihlala inezixhobo kunye namava ale mitsiko isemi-standard. Indawo yabo kufutshane nonxibelelwano olukhulu lwezothutho olunje ngeBeijing-Guangzhou Railway ithetha ukuba ulungiselelo lweeodolo ezininzi lunokulungelelaniswa, okubalulekileyo xa usenza iprototyping kwaye ufuna iisampulu eziphindaphindwayo ngaphandle kokulibaziseka okukhulu.

Itrayi engaphumelelanga yayikwisibiyeli sokuxhoma unogada. Sifumene ibholiti enesiqingatha esisezantsi kumrhwebi jikelele. Ububanzi be-shank babusezantsi kwebhendi yokunyamezela, kwaye unyango lobushushu lwalungahambelani. Phantsi komthwalo oguqukayo, isibiyeli siphuhlise i-slop. Kuye kwafuneka ukuba sibuyise ingeniso ngenxalenye efunyenwe ngokufanelekileyo, ebiza imali eninzi emsebenzini kunokonga okokuqala kwisiqhoboshi. I-takeaway: ixabiso lokusilela ngokudibeneyo lihlala lincinci ixabiso lesibophelelo esifanelekileyo.

IiNuances zeSicelo kunye nesizathu sokuba ungemva kweNkcazo

Ngaphandle kokucheba kunye nokulungelelaniswa, icandelo elingafundwanga lisebenza ezinye iinjongo. Kwizicelo zombane, inokusebenza njengepaseji ye-insulated. Kwii-hydraulic manifolds, inokubonelela ngomphezulu wokutywina ococekileyo we-O-ring enokuthi idibaniswe yimicu. Ndibalule iziqhoboshi ezinesiqingatha ukuze zisetyenziswe njengeepivots okanye iiasi kwiindlela ezinesantya esiphantsi, apho umsonto ufuneka kuphela kwi locknut kwelinye icala.

Ubude bomsonto ngokwawo sisibalo, hayi intelekelelo. Kufuneka ibe yinde ngokwaneleyo ukuba ibandakanyeke ngokupheleleyo kwi nut okanye emngxunyeni ocofelweyo (udla ngo-1-1.5 umphinda-phinde ngobubanzi) kunye mhlawumbi nentambo okanye emibini yokunyamezelana, kodwa hayi ixesha elide kangangokuba liyaphuma okanye liphazamise. Ubude be-shank kufuneka buhambelane nobukhulu obudibeneyo bezinto eziboshiweyo, thabatha nayiphi na i-washers. Ukufumana oku kungalunganga kuthetha ukuba iintambo zibandakanya umngxuma wokucoca, ukoyisa injongo. Ndihlala ndizoba umdibaniso, ndilinganise yonke into, kwaye emva koko ndongeza i-fastener spec. Ibonakala isisiseko, kodwa isoloko ingahoywa.

Enye i-nuance: i-torque yokufakela. Nge isiqhoboshi sesiqingatha, i-torque isetyenziswe ngokuyinhloko ukunweba ibholithi kunye nokudala umthwalo we-clamp kwi-shank, kungekhona ukunqoba i-thread friction kwiinqununu ezininzi. Oku ngamanye amaxesha kunokukhokelela ekulayisheni kwangaphambili okuhambelanayo. Nangona kunjalo, ukuba i-shank inde kakhulu kwi-stack yezinto eziphathekayo, ugqiba ukujijisa ngokuchasene nemicu esemngxunyeni wokucoca, leyo yindlela eqinisekileyo yokuhluba into okanye ukubangela ukufundwa kwe-torque yobuxoki.

Xa iHalf Fastener ayiyompendulo

Ayisosisombululo sehlabathi. Kwimithwalo eqinileyo apho ulungelelwaniso lungabalulekanga, ibholithi enemisonto epheleleyo ilula kwaye inexabiso eliphantsi. Ukuba amalungu adibeneyo azizizixhobo ezithambileyo njengemithi okanye iplastiki, imisonto elumayo kuzo zombini iziqwenga inokubonelela ngamandla okubamba angcono. Kwakhona, kwiindawo ezishukumayo eziphakamileyo kakhulu, unokufuna into etshixayo ezinikeleyo kumsonto nakanjani na, ukwenza inzuzo yokucheba yoyilo lwesiqingatha ibe ngaphantsi kwesigqibo.

Ndakhe ndatyhala isiqingatha-i-fastener kwindibano yentsimbi yeshiti apho amalungu abambeneyo ayebhityile kakhulu ukuba angabonelela ngomthi owaneleyo we-shank. Isiphumo yaba yi-deformation yendawo ejikeleze umngxuma. Satshintshela kwi-screw enemisonto epheleleyo kunye nentloko ene-flanged kunye ne-serrated washer-intambo kwisiqwenga sesibini inikezela ukuxhathisa okufunekayo. Ixabiso lesixhobo sebholithi yamagxa esiko lalingathethelelwanga. Ukwazi ixesha lokungasetyenziswa kubaluleke njengokwazi ixesha lokulichaza.

Isitshixo kukuhlalutya umendo womthwalo. Ngaba ukucheba kungamandla abalaseleyo? Ngaba ulungelelwaniso oluchanekileyo okanye ibhore ecocekileyo iyimfuneko? Ngaba kukho imfuneko yokutywina okanye yokugquma? Ukuba impendulo kuyo nayiphi na kwezi, ngoko a isiqhoboshi sesiqingatha isuka kukhetho ukuya kumgqatswa owomeleleyo. Lukhetho olusebenzayo loyilo, hayi nje ukwahluka kwebholithi eqhelekileyo.

Iingcinga zokuGqibela ekuBaluleni nasekuFundeni

Xa ufuna i-fastener yesiqingatha, umzobo wakho kufuneka ucace: ubude obupheleleyo, ubude be-shank kunye nobubanzi (ngokunyamezela), ubude bentambo kunye nokucaciswa, isitayela sentloko, ibakala lezinto eziphathekayo, kunye nokugqiba. Musa ukubhala ibholithi yomsonto osiqingatha. Eso sisimemo somthengisi ukuba athumele nantoni na enayo ngokomlinganiselo ofanayo.

Ukukhangela okuthembekileyo, ngakumbi kwiiprojekthi ezifuna ukuhambelana, ukusebenzisana nomenzi okhethekileyo kububulumko. Inkampani efana I-Sunnian Zitai Festener Fishaner Comment Com. (https //wwww.ziitasteners.com), emi kwindawo yemveliso engundoqo, ngokuqhelekileyo inamandla okusingatha ezi zicelo zikhethekileyo ngokufanelekileyo. Ukusondela kwabo kwimizila emikhulu yezothutho kuyinzuzo ebonakalayo yokulawula ixesha lexesha lokubonelela, eliyinxalenye engeyonto encinci ye-equation yokuthengwa kwempahla. Awuthengi nje into yokubopha; uthenga ukukwazi ukuyivelisa kwi-spec ethembekileyo.

Ekugqibeleni, i-fastener yesiqingatha ngumzekelo ogqibeleleyo wendlela icandelo lomatshini elichanekileyo elichazwe ngumsebenzi walo kwindibano, kungekhona ngegama layo kwikhathalogu. Sisixhobo esinobuqili, kodwa kwindibaniselwano elungileyo, ngumahluko phakathi kwento esebenzayo kunye nento ebambekayo.
