Ndedzipi mwero wekuyedza wekuzviisa wega ?

Usati watumira, Kuzvibata-kuteedzera zvinopa kunofanirwa kuongororwa kunotevera kuongororwa zvichienderana nemitemo yenyika uye maindasitiri maitiro. Izvo chete zvinopfuura ongororo dzinogona kusunungurwa:

1. Chitarisiko uye zviyero

– Threads inofanira kuve yakasimba, pasina urema kana burrs; Musoro uye muswe unofanirwa kunge usina kusvibiswa; Iyo pamusoro inofanira kuve yakatsetseka, isina ngura uye inokwenenzverwa.

– Shandisa Caliper Gauges, Mhete Gauges, uye plug gauges kusvika kune zvakasarudzika ongorora zviyero zvikuru (Outer diamita, kureba, pitch, Thread angle). Mishonga inofanirwa kuenderana nemadhirowa kana GB / T 196/197 zvinodiwa.

2. Kuomesa uye kudengenyeka kwechidimbu

– Kumusoro kuomarara: Martensipic Simbi ≥300 HV; Core kuomarara kwakadzorerwa zvinoenderana neyekunyama giredhi (20H / 25h, etc.).

– Yakavharwa yakadzika pakadzika: Maererano neGB / T 3098.7, matatu samples inofanira kutorwa kubva kune imwechete batch, uye kukosha kwakayerwa kunofanirwa kunge kuri pakati peiyo yepamusoro uye yakaderera miganhu yezvinyorwa zvekugadzira.

3. Kuputsa Torque

– Nyorera torque zvishoma nezvishoma pane yakazvitsaurira kudzika kusvikira maperembi, uye rekodha kutyora torque kukosha; Inofanira kunge iri ≥ iyo shoma kukosha kwakapihwa patafura 5 ye standard gb / t 3098.21 (e.e., St4.2-30h kwete yakaderera pane 3.9 N · m).

4. Screw-mukuita

– Screw iyo isa muyedzo yekuyedza yeAluminium Alloy (80-120 Hv) kana yakaderera carbon simbi (130-170 Hv) yeiyo yakatsanangurwa gobvu uye gomba diameter kusvikira imwe chete yakazara tambo kubuda; Iyo tambo haifanire kubviswa kana chipped, uye iyo torque torque inofanira kunge yakatsetseka uye isina jamming.

5. Tensile / Torsion Kuchengeta Simba (Kuti uzvibate simbi inserts)

– Mushure mekuiswa pane yakajairwa aluminium test block, Nyorera iyo yakataurwa preload ne torque wrench; Iyo Inisa haina kutenderedza kutenderwa; ramba uchishandisa depto-kunze simba, uye inoonekwa seinopfuura (vanokwanisa) Kana isingabudisi kunze kana kukosha kwekugadzira kwasvikwa.

6. Kubata uye Kudzivirirwa Corrosmion (Kana zvichishanda)

– Kukoka ukobvu kuchaedzwa maererano neGB / T 5267.1; Pasina Kwakarere Salt Spray Test ≥ 48 H ine nguwo tsvuku; kushamisika kunosangana nazvo “Kuyambuka-cheka giredhi 1” zvinodiwa.

7. Kurongedza uye kunyora

– Maererano neGB / T 90.2: Bhegi remukati rinofanira kusanganisira chitupa chekuenderana (kusanganisira batch nhamba, zvinhu, Zvinyorwa, uye kuwanda); Bhokisi rekunze rinofanira kubatanidzwa nehuremu-chiratidzo uye kuvhundutsa-chiratidzo labels, uye inoperekedzwa neyekutumira kuongorora mushumo.

Izvo zvinhu zviri pamusoro ndezve maitiro maitiro ekufungidzira zviri mukati; Kana mutengi aine zvakakosha zvinodiwa (sehupenyu hwehunyoro, Torque Attenuation, Rohs, Dfar), inoenderana bvunzo inogona kuwedzerwa uye inosanganisirwa muChiMhando Yekubvumirana.
