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 uye nzungu anoshandiswa zvakanyanya mukugadzirwa kwemashedhi, mabhiriji, madhamu uye magetsi. kana arc welding uchishandisa electrodes, zvichienderana nekudiwa kwekubatanidza simbi ndiro uye danda.Each yekubatanidza nzira ine zvayakanakira nezvayakaipira, izvo zvatichaongorora pazasi.
Zvigadziriso zvemasiruu zvinoshandiswa pakuvaka danda rekubatanidza zvinogadzirwa nesimbi yepamusoro-giredhi, kazhinji giredhi 10.9 simbi.Grade 10.9 zvinoreva kuti tensile simba density ye structural screws inosvika 1040 N/mm2, uye inokwanisa kumira kusvika 90% yezvose. kushushikana kunoshandiswa kune screw body munharaunda elastic isina deformation yekusingaperi.Kuenzaniswa ne4.8 iron, 5.6 iron, 8.8 yakaoma simbi, structural screws ane yakakwirira tensile simba uye ane zvakanyanya kuoma kupisa kurapwa mukugadzira.
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.
