Hino Fuso Universal Rear Bolt

1, Spheroidizing annealing yemabhaudhi akasimba

Kana iyo hexagon socket musoro mabhaudhi inogadzirwa neinotonhora yemusoro maitiro, iyo yekutanga chimiro chesimbi inozokanganisa zvakananga kugona kuumba panguva yekutonhora musoro kugadzirisa. Nokudaro, simbi inofanira kuva nepurasitiki yakanaka. Kana iyo kemikari yesimbi inogara iripo, iyo metallographic chimiro ndicho chinhu chakakosha chinotaridza mapurasitiki. Zvinowanzotendwa kuti coarse flaky pearlite haikodzeri kutonhora musoro kuumbwa, nepo yakanaka spherical pearlite inogona kuvandudza zvakanyanya kugona kwepurasitiki deformation yesimbi.
Kune yepakati kabhoni simbi uye yepakati kabhoni alloy simbi ine huwandu hukuru hwepamusoro-simba fasteners, spheroidizing annealing inoitwa pamberi inotonhora musoro, kuitira kuti uwane yunifomu uye yakanaka spheroidized pearlite kuti ikwane zvirinani zvinodikanwa zvekugadzira.

2, Kudhirowa uye kudzika kwemabhaudhi akasimba

Maitiro ekubvisa iron oxide plate kubva kunotonhora musoro waya yesimbi tsvimbo iri kukurura nekudzika. Pane nzira mbiri: mechanical descaling uye makemikari pickling. Kutsiva kemikari yekunhonga yetsvimbo yewaya nemechani descaling inovandudza chibereko uye inoderedza kusvibiswa kwezvakatipoteredza. Iyi nzira yekudzikisa inosanganisira nzira yekukotama, kupfapfaidza nzira, etc. The descaling mhedzisiro yakanaka, asi yasara simbi sikero haigone kubviswa. Kunyanya kana chiyero chesimbi oxide chikero chakasimba kwazvo, saka iyo mechanical descaling inobatwa nehupamhi hwesimbi chiyero, chimiro uye mamiriro ekunetseka, uye inoshandiswa mu carbon steel wire rods kune yakaderera-simba fasteners. Mushure mekugadzirwa kwema mechanical, tambo yewaya ye-high-simba fasteners inopinda kemikari pickling process kuti ibvise zviyero zvose zvesimbi oxide, kureva, kuderera kwekomboni. Kune yakaderera kabhoni simbi waya tsvimbo, simbi shiti rakasiiwa nekudzika kwemakanika rinogona kukonzeresa kusakara kwezviyo kugadzira. Kana gomba rezviyo rikanamatira pashizha resimbi nekuda kwekukweshana kwetambo yewaya uye tembiricha yekunze, pamusoro petsvimbo yewaya inoburitsa mareba ezviyo.
