Uhlobo olwahlukileyo lwebholithi
Umahluko phakathi kweebholiti kunye nezikrufu ulele kwimiba emibini: enye imilo, inxalenye ye-stud yebholithi ifunwa ngokungqongqo ukuba ibe yi-cylindrical, isetyenziselwa ukufaka i-nut, kodwa inxalenye ye-stud ye-screw ngamanye amaxesha i-conical okanye kunye ne-tip; enye iSebenzisa umsebenzi, isikrufu sijijwa kwizinto ekujoliswe kuzo endaweni ye nut. Kwizihlandlo ezininzi, iibholiti nazo zisebenza ngokwazo, kwaye zikrwelwe ngokuthe ngqo kumngxunya odityanisiweyo wangaphambili, ngaphandle kwesidingo se nut ukusebenzisana nayo. Ngeli xesha, i-bolt ihlelwa njenge-screw ngokwemiqathango yomsebenzi.
Imilo kunye nenjongo yentloko yebholithi yahlulwe ibe yi-hexagonal head bolts, iibholiti zentloko yesikwere, iibholiti zentloko ezisisiqingatha-round, iibholiti zentloko eziphikisayo, iibholiti ezinemingxuma, iibholiti ze-T, iibholiti zentloko (isiseko) njalo njalo.
Umsonto wekholamu unokwahlulwa ube ngumsonto orhabaxa, umsonto ocolekileyo kunye nomsonto we-intshi, ngoko ubizwa ngokuba yi-bolt entle kunye ne-inch bolt.
Inkqubo yeMveliso
Okokuqala, i-punch yokuqala ihambisa ukulungisa ucingo lokuyila, kwaye emva koko i-punch yesibini ihambisa ukubumba ucingo kwakhona kwaye imise imveliso egqityiweyo. Kwinkqubo yesihloko esibandayo, ukufa okumiselweyo (ukufa koxinzelelo) kunye nesitampu (ukubetha) kufa (ukubetha)
Inani leentloko) alifani. Ezinye izikrufu ezintsonkothileyo zinokufuna iipuntshi ezininzi ukuba zenze kunye, ezifuna izixhobo ezininzi zesikhululo ukwenza i-screw yenze i-screw.Emva kokuhamba kwe-punch, intloko ye-screw igqityiwe, kodwa inxalenye ye-screw shaft ayizange ifakwe i-threaded.Indlela yokwenza i-screw thread i-thread rolling. Ukuqengqeleka komsonto kusetyenziso lweentsizi ezimbini ezijikelezayo ezijikelezayo (iipleyiti zokuhlikihla) ezinamazinyo acudiweyo ukucudisa indawo engenanto ejikelezileyo eyenziwe sisitishi esinezitishi ezininzi okanye umatshini wokuhombisa phakathi.
Emva kwentloko kunye nokuxubha amazinyo, isikrufu sonke senziwe. Ngokuqinisekileyo, ukwenzela ukuba ukubonakala kwe-screw kuqaqambe kwaye kube ngcono, inkqubo yonyango yomphezulu iqhele ukwenziwa. Okufana nokucocwa kunye nokunyanzeliswa kwezikrufu zentsimbi estainless, i-electroplating kumphezulu we-carbon steel screws, njl njl. Yenziwe ngemibala eyahlukeneyo ye-screw fasteners.
