Nzira yekusarudza sei fastener yakarurama? Ndeapi maparamita akakosha aunoda kuziva?
Kana zvasvika pakusarudza iyo yekusungirira chaiyo yeprojekiti yako, pane akati wandei akakosha zvinhu zvekufunga. Kubva pazviyero zvechigadzirwa uye zvakatemwa kusvika kune zvekushandisa, magiredhi esimba, uye mabatirwo epamusoro, chinhu chimwe nechimwe chinoita basa rakakosha mukuona mashandiro uye kuvimbika kwechisimbiso. Muchinyorwa chino, isu tichaongorora zvakadzama mafungidziro ekusarudza iyo yekumisikidza kwayo, tichipa ruzivo rwehunyanzvi kuti ikubatsire kuita sarudzo ine ruzivo.
Product Standards uye Zvinotsanangurwa
Danho rekutanga pakusarudza chisungiso chakakodzera ndechekunzwisisa zviyero zvechigadzirwa uye zvirevo zvachinoshandiswa. Zvemafasteners anotevera chaiwo mwero, senge DIN912 (hexagon socket head screws), iyo yakamaka yakajairwa nhamba inogona kunyatso ratidza dhizaini nekuita kwavo. Mukushayikwa kwezviyero zvakajeka, zvikamu zvisiri-standard (zvisiri-standard zvikamu) zvinoda mifananidzo yakadzama kuti iratidze hukuru hwavo uye chimiro. Pasi rose, The German Institute for Standardization (DIN), The International Organization for Standardization (ISO), Chinese national standards (GB), American National Standards Institute (ANSI) uye Japanese Industrial Standards (JIS) ose ane simba guru remitemo.
Fastener specifications kazhinji ine zvikamu zviviri: thread diameter uye screw urefu. Metric neINCH ndiwo maviri makuru ekutsanangurwa masisitimu. Metric screws seM4-0.7x8, apo M4 inomiririra shinda yekunze dhayamita ye4mm, 0.7 ndiyo pitch, uye 8 ndiko kureba sikuruu. INCH masiruu se6#-32*3/8, apo 6# inomiririra dhayamita rekunze, 32 inomiririra huwandu hweshinda painji imwe yehurefu hweshinda, uye 3/8 ndiyo kureba sikuruu.
Zvishandiso
Izvo zvinhu zve fasteners zvinosarudza simba ravo, corrosion kuramba uye hupenyu hwebasa. Zvishandiso zvakajairika zvinosanganisira kabhoni simbi, Stainless simbi, Stainless simbi, mhangura, aruminiyamu, etc. Carbon simbi inogona kupatsanurwa kuita low kabhoni simbi, medium carbon simbi, high carbon simbi uye alloy simbi, akadai SCM435, 10B21, etc. Kazhinji Stainless simbi dzinosanganisira SS302, SS304, SS316 nharaunda yayo yakasiyana, nezvimwe zvinhu zvakasiyana-siyana, nezvimwewo. Zvinhu zvakadai sekuramba corrosion, simba, uye kushivirira tembiricha zvinofanirwa kuongororwa kana uchisarudza zvinhu zvechitsigiro chako kuti uone kuti inogona kumira nemamiriro akatarisirwa.
Simba MaGrade
Kunyanya kune kabhoni simbi fasteners, ivo vanowanzo kupatsanurwa mumagiredhi esimba akasiyana zvichienderana nekusimba kwavo uye simba regoho. Kunzwisisa magiredhi esimba kwakakosha pakuona kuti chisungo chinogona kumirisana nemitoro inodiwa pasina kukundikana. Magiredhi akajairwa anosanganisira 4.8, 5.8, 6.8, 8.8, 10.9, 12.9, etc. High-simba screws sezvigadzirwa pamusoro pe8.8 kazhinji inoda kudzikamiswa uye kupisa kunorapwa kuti kunatsiridza mashandiro avo.
Surface Treatment
Kurapa kwepamusoro kunonyanya kuwedzera kusimba kwekuora uye aesthetics yemafasteners. Nzira dzinowanzoitwa dzekurapa dzinosanganisira kusviba, galvanizing (zvakadai seblue-white zinc plating, white zinc plating, etc.), copper plating, nickel plating, chrome plating, etc. Kune zvakatipoteredza uye zvisingasviki zvakatipoteredza galvanizing layers, uye ukobvu hwekuputira huchakanganisawo mhinduro yekuongorora munyu. Kusarudza nzira yakakodzera yekurapa kwepamusoro zvinoenderana nenharaunda yekushandisa uye zvinodiwa zvinogona kunyatso kuwedzera hupenyu hwesevhisi yezvitsigiro.
Muchidimbu, kana uchisarudza zvekusungirira, zvinhu zvakaita sezviyero zvechigadzirwa, mataurirwo, zvinhu, mazinga esimba, uye marapirwo epamusoro zvinoda kunyatsotariswa kuti zvinosangana nezvinodiwa zvekushandisa uye kuita zvakanaka uye hupenyu hurefu.Ingave yekuvaka, yemotokari, yemuchadenga, kana chero imwe indasitiri, chisungiso chakakodzera chinhu chakakosha mukubudirira kwechero application.
