Mabasa eMuchina weHoning muPiston Ring Production
| Function | Tsanangudzo |
|---|---|
| Dimensional Precision | Yekupedzisira saizi yemhete ID/OD kusvika mukati me ± 0.001–0.002 mm. |
| Roundness uye Cylindricity Correction | Inobvisa kukanganisa kunokonzerwa nekupisa kurapwa kana kumberi machining. |
| Surface Pedzisa Kuvandudza | Inowana girazi-rakafanana kana kuti nzvimbo yakati sandara (Ra ≈ 0.1–0.3 µm). |
| Oil Retention Surface | Inogadzira micro-cross-hatch or plateau texture kuti inyatsozora. |
| Yakaderedzwa Friction uye Wear | Inovandudza piston mhete kushanda uye injini kushanda zvakanaka. |
Mafambisirwo Anoitwa Hurukuro (Step-by-Step)
1. Workpiece Kugadzirira
Piston mhete dzakasungwa kanamumwe nomumwekana mukatistackspana aprecision mandrel.
Iyo honing muchina inoiswa maereranosaizi yemhete uye zvinhu(kazhinji simbi, simbi, kana molybdenum-yakavharwa mhete).
2. Honing Tool Setup
A kukudza mandrel kana musoroakakwanamatombo abrasiveinoshandiswa.
Iyo abrasives inowanzodiamondi, CBN (cubic boron nitride), kana aluminium oxide, zvichienderana nekuoma kwemhete uye kupedzisa zvinodiwa.
Matombo ndiwoexpandable, kushandisa yunifomu kudzvinyirira mukati kana kunze kwepamusoro.
3. Honing Operation
(a) Engagement uye Motion
Musoro wekukudzainotenderera(kazhinji 200-600 rpm) panguvakudzorera axiallypahuwandu hwepamusoro (20-60 shamhu / min).
Izvi zvakasanganiswa kufamba zvinocheka chaiyo, yakafanana nzvimbo uye inogona kugadzira amicro-cross{1}}hatch patternpazvinenge zvichidiwa.
(b) Kudzorwa Kudzvinyirira uye Kudyisa
Hydraulic kana servo{{0}inodzorwa kuwedzera kunoshandisa kumanikidza kusingachinji kuti ive nechokwadi chekubviswa kwestock.
Kubvisa zvinhu kushoma - kazhinji5–20 µm- asi zvine huronyo hwepamusoro hwejometri.
(c) Coolant Flow
Honing oiri kana synthetic inotonhorera inobvisa zvidimbu zvakanaka, mafuta, uye inotonhodza zvese zviri zviviri workpiece nemaabrasives.
4. Maitiro Monitoring uye kuyerwa
-mukuita gaugingkanamhepo yekuyera masisitimutarisa kukura kwebore kana ring ID nenguva chaiyo.
Automatic size shut-kuzimwa kunoita kuti ring imwe neimwe ikwane.
Kugadzirwa kwe-kukwirisa,akawanda{{0}muchina wokuruka mapuraneti kana kuti mapuranetianoshandiswa pakukudza panguva imwe chete yezvindori zvakawanda.
5. Kupedzisa (Plateau kana Mirror Honing)
Iyo yekupedzisira pass inoshandisamatombo akatsetseka{{0}kutsvedzerera pamusoro pepamusoro uchisiya mafuta-mipata inochengeta.
Izvi"plateau honing" inogadzira chimiro chinodzorwa chinoderedza kusakara panguva yekutanga injini kumhanya-muchikamu.
Inoburitsa Surface uye Dimensional Characteristics
| Parameter | Typical Value | Chinangwa |
|---|---|---|
| ID/OD Kushivirira | ±0.001–0.002 mm | Yakakwana yekuisa chisimbiso inokodzera mupiston groove uye cylinder bore |
| Roundness | Zvishoma pane kana kuenzana ne1.0 µm | Smooth kutenderera uye yunifomu kumanikidza |
| Kushata Kwepamusoro (Ra) | 0.1–0.3 µm | Optimized kutsvedza uye kudzora mafuta |
| Cross-Hatch angle | 20-40 dhigirii (kana zvichidikanwa) | Kuchengetedzwa kwakakodzera kwemafuta nekuzora |
| Plateau Ratio | 60–80% | Kumhanya-mukati uye kusapfeka |
Honing Configurations yePiston Rings
| Type | Tsanangudzo | Application |
|---|---|---|
| Internal Honing | Inokwenenzvera dhayamita yemukati (yepiston groove fit) | Most common |
| External Honing | Inopedza dhayamita yekunze (ye cylinder contact surface) | Inoshandiswa kunyatso kudzora ring-bore interface |
| Flat Surface Honing | Inopedza zviso zvemhete dzemhete | Kutsvedza kwakatsetseka mumapiston grooves |
| Planetary Honing Machines | Multiple spindles inokwenenzvera mhete dzinoverengeka panguva imwe chete | Mitsetse yekugadzira -huwandu |
Summary
| Aspect | Tsanangudzo |
|---|---|
| Kuda Honing | Kuti uwane kurongeka kwepamusoro, kutsvedzerera, uye mafuta-anodzoreredza nzvimbo pamarin'i episton kuti injini ivhare uye nekupfeka hupenyu. |
| Main Mabasa | Dimensional kururamisa, kutenderera kugadziridzwa, kupedzisa kwepamusoro, uye kuumbwa kwemafuta ekuzora. |
| Maitiro ekugadzirisa | Inodzorwa abrasive kucheka uchishandisa matombo anotenderera uye anodzokerana pasi pekugara kunotonhorera kuyerera. |
| Mugumisiro | Consistent ring geometry, kutsika kwakaderera, kwakaringana kudzora mafuta, uye kusimba kwakasimba mukushanda kweinjini. |
