Sechinhu chakakosha mukubatanidza kwemakanika, kusarudzwa kwemafasteners 'paramita kwakakosha pakuona kugadzikana uye kuchengetedzeka kwekubatanidza.
1. Zita reChigadzirwa (Standard)
Iyo fastener chigadzirwa zita rakabatana zvakananga nechimiro chayo uye mamiriro ekushandiswa. Kune mafasteners anoenderana nemwero chaiwo, kunyora nhamba yakajairwa kunogona kunyatso ratidza dhizaini nekuita kwavo. Mukushayikwa kwezviyero zvakajeka, zvikamu zvisingaenzaniswi (zvisiri-zviyero zvikamu) zvinoda mifananidzo yakadzama kuti iratidze zviyero uye maumbirwo avo.
2. Zvinotsanangurwa
Tsanangudzo yezvisungo kazhinji ine zvikamu zviviri: dhayamita yeshinda uye kureba kwescrew. Iwo metric uye maAmerican masisitimu ndiwo maviri makuru ekutsanangura masisitimu. Metric screws seM4-0.7x8, apo M4 inomiririra shinda yekunze dhayamita ye4mm, 0.7 inomiririra pitch, uye 8 inomiririra sikuruu kureba. Masiruuru ekuAmerica akadai se6 # -32 * 3/8, apo 6 # inomiririra dhayamita rekunze reshinda, 32 inomiririra nhamba yeshinda painji imwe yehurefu hweshinda, uye 3/8 ndiyo kureba kwesiruu.
3. Zvinhu
Izvo zvinhu zvezvitsigiro zvinotarisa simba razvo, corrosion resistance, uye hupenyu hwebasa. Zvinhu zvakajairika zvinosanganisira kabhoni simbi, Stainless iron, Stainless iron, mhangura, aruminiyamu, etc. Carbon steel inogona kupatsanurwa kuita low carbon steel, medium carbon steel, high carbon steel, uye alloy steel. Izvo zvakakosha kuti usarudze iyo yakakodzera zvinhu zvichibva pane yekushandisa mamiriro uye kuita zvinodiwa.
4. Mwero wesimba
Kune carbon steel fasteners, giredhi resimba rinoratidza simba ravo rekusimba uye kusimba kwegoho. Zviyero zvakajairika zvinosanganisira 4.8, 5.8, 6.8, 8.8, 10.9, 12.9, etc. High simba screws, zvakadai sezvigadzirwa zvegiredhi 8.8 kana pamusoro, kazhinji zvinoda quenching uye kudziyisa kupisa kurapwa kuti kunatsiridza dzavo michina zvinhu.
5. Kurapa kwepamusoro
Kurapa kwepamusoro kunonyanya kunangana nekuwedzera corrosion resistance uye aesthetics yezvitsigiro. Nzira dzakajairwa dzekugadzirisa dzinosanganisira kusviba, galvanizing (zvakadai sebhuruu nechena zingi, zingi chena, nezvimwewo), mhangura yekuisa, nickel plating, chrome plating, nezvimwe. hupenyu hwesevhisi yemafasteners.
Muchidimbu, kana uchisarudza zvekusungirira, zvinofanirwa kunyatso tarisa zvinhu zvakaita sezita rechigadzirwa (standard), maratidziro, zvinhu, giredhi resimba, uye kurapwa kwepamusoro kuti ive nechokwadi chekuti zvinosangana nezvinodiwa zvekushandisa uye kuita zvakanaka uye hupenyu hurefu.
