Industrial screws inogadzirwa mumhando dzakasiyana-siyana uye zviyero.Steel alloys ane yakakwira kwazvo kugona kumisa kushushikana kwakanyanya pasi pesimba rekupisa kurapwa, zvichitungamira kusarudzo yeiyi alloy pakugadzira mabhaudhi esimbi anoshandiswa mumaindasitiri zvimiro.Ferroalloy simbi dzine mwero. high carbon content uye zvinhu zvakakwirira zvakanyanya kudarika iron yakachena, iyo yakanyanya kupfava.Chokwadi, kunze kwekabhoni, kugadzikana kwezvinhu zvakadai semanganese, silicon, sulfur, phosphorus, uye dzimwe nguva kunyange vanadium (vanadium inowedzerwa kune simbi yesimbi inoda elasticity) anowanikwa mumisanganiswa yesimbi.
Muindasitiri yekuvaka, mabhaudhi ezvimiro uye nzungu anoshandiswa zvakanyanya mukugadzirwa kwemashedhi, mabhiriji, madhamu uye magetsi zvidyarwa.Kutaura zvazviri, kushandiswa kwemabhaudhi ezvimiro uye nzungu kunoitwa zvakachinjana nesimbi dzesimbi, izvo zvinoreva kuti angave mabhaudhi echimiro kana arc welding. kushandisa ma electrodes, zvichienderana nekudiwa kwekubatanidza ndiro yesimbi uye danda.Nzira imwe neimwe yekubatanidza ine zvayakanakira nezvayakaipira, izvo zvatichaongorora pazasi.
Structural screws anoshandiswa mukuvaka matanda ekubatanidza anogadzirwa nesimbi yepamusoro-giredhi, kazhinji giredhi 10.9.Grade 10.9 zvinoreva kuti tensile simba density ye structural screw inosvika 1040 N/mm2, uye inokwanisa kumira kusvika 90% yekushushikana kwese. inoshandiswa kune screw body munharaunda elastic isina deformation yekusingaperi.Kuenzaniswa ne 4.8 iron, 5.6 iron, 8.8 yakaoma simbi, structural screws ane yakakwirira tensile simba uye ane zvakanyanya kuoma kupisa kurapwa mukugadzirwa.
Yakasiyana neyakajairwa hexagon mabhaudhi nenzungu, iyo yakajairwa hexagon mabhaudhi nenzungu inogadzirwa zvinoenderana neDIN931 yakajairwa sehafu yegiya, zvinoenderana neDIN933 yakajairwa semagiya akazara, uye hexagonal screws iri nyore, kazhinji inogadzirwa zvinoenderana neDIN6914 standard.Coupling nuts on structural screws anewo nyama yakawanda uye kureba kupfuura mwero hex nzungu anogadzirwa kuDIN934, achiratidza kushushikana kwakanyanya, anogadzirwa kuDIN6915.Masikiru echivakwa ichi akanyorwa 10HV uye anowanzo matt black phosphating yekuvandudza nharaunda inodzivirira kana kupisa dip galvanized kana kudzika. chrome matt sirivheri, zvose zvine metallic finish.Izvo zvinoshandiswa mu zinc uye zvine kurwisana kwakanaka kwezvakatipoteredza.
