1. Chifukwa Chiyani Makina Ochizira Amafunikira
Popanga masilinda a hydraulic,honing ndi imodzi mwazofunikira kwambiri kumaliza ntchitochifukwa zimatsimikizira mwachindunjikugwira ntchito, kuchita bwino, komanso moyo wautaliza hydraulic system.
Masilinda a Hydraulic amasintha mphamvu ya hydraulic kukhala makina oyenda, ndipo izi zimatengerapamwamba khalidwe ndi geometrycha mkati mwa chubu cha silinda.
Ngakhale zofooka zazing'ono - kuchepekera, kukhwinyata, kukhwinyata, kapena -kwa{2}}kuzungulira - kungayambitse:
Kutaya zisindikizo zakale,
Kusuntha kosakhazikika kwa pistoni,
Kuvala msanga kwa zisindikizo ndi pistoni, ndi
Kutaya mphamvu chifukwa cha kukangana mkati.
Chifukwa chake, kuwongolera ndikofunikira:
Pezani -zolondola kwambiri za geometry(kuwongoka, cylindricity, ndi kuzungulira mkati mwa ± 1-2 µm).
Pangani mawonekedwe olondola a pamwamba(panjira ya crosshatch) posungira filimu yamafuta ndi kayendedwe ka pistoni kosalala.
Chotsani zinthu zotsalira ndi kupsinjika maganizokusiyidwa ndi-machining kale (monga kubowola kapena kubowola kwakuya).
Onetsetsani kusindikiza kwangwiro ndi kukangana koyendetsedwapakati pa pistoni ndi khoma la silinda.
Wonjezerani kukhazikikaya silinda ndi kuwonjezera moyo wautumiki.
2. Ntchito za Honing Machine mu Hydraulic Cylinder Manufacturing
A makina osindikiziraamachita zonse ziwirikukonzandikumalizaamagwira ntchito mkati mwa chubu cha silinda.
| Ntchito | Kufotokozera | Zotsatira / Cholinga |
|---|---|---|
| Kuwongolera kwa Geometry | Imachotsa taper, mawonekedwe a mbiya, ndi kutsetsereka komwe kumasiyidwa ndi makina akale. | Mawonekedwe abwino a cylindrical amatsimikizira kugawa kwamphamvu kofanana. |
| Kulondola kwa Dimensional | Imakwanitsa kukula komaliza ndi micron-level control. | Imathandizira kukwanira bwino pakati pa pistoni ndi bore. |
| Surface Texture Control | Amatulutsa ngodya yowongoka (nthawi zambiri 30 digiri -45 digiri). | Imakulitsa kusungidwa kwamafuta ndi kusindikiza. |
| Surface Finish Kupititsa patsogolo | Amachepetsa mtengo wa Ra kukhala 0.1–0.4 µm kutengera kapangidwe kake. | Malo osalala, osasinthasintha amachepetsa kukangana. |
| Deburring ndi Edge Smoothing | Imachotsa -zing'onoting'ono kapena zitsulo zopindika kuti zisatope. | Imateteza kuwonongeka kwa chisindikizo panthawi yosonkhanitsa. |
| Kuchepetsa Kupsinjika Maganizo | Imachotsa kutentha-zigawo zomwe zakhudzidwa kapena kupsinjika kotsalira. | Imawongolera kukhulupirika ndi kukhazikika kwamapangidwe. |
3. Momwe Honing Process imachitikira (Step-by-Step)
Kuwongolera kwa machubu a hydraulic silinda nthawi zambiri kumachitika pa ahorizontal hydraulic kapena CNC-controlled honing machine, chifukwa machubu a silinda ndi aatali ndipo amafunikira kukhazikika kokhazikika komanso kupanikizika kosasinthasintha motsatira kutalika kwake.
Khwerero 1: Pre{1}}Kukonza
Silinda chubu ndidzenje lakuya lobowola kapena lotopetsampaka 0.3-0.5 mm kuchokera m'mimba mwake yomaliza.
Pamwamba pake pakhoza kukhala ndi zomangira zowoneka bwino kapena taper yaying'ono.
Khwerero 2: Kuyika ndi Kukhazikitsa
chubu ndiwokwezedwa mopingasapa makina opangira honing pogwiritsa ntchito zothandizira zapadera kapena zoyandama zoyandama.
A honing mandrel (chida)opangidwa ndi miyala yonyezimira (aluminium oxide, silicon carbide, kapena diamondi/CBN) amalowetsedwa kudzera pa bore.
Mafuta oyeretsera kapena ozizira amaperekedwa mosalekeza kuti achotse zinyalala ndikuziziritsa pamwamba.
Khwerero 3: Kuwongolera magwiridwe antchito
Rotary Motion:The honing mandrel imazungulira mkati mwa bore (nthawi zambiri 100-300 rpm).
Kubwereza:The mandrel amasuntha mmbuyo ndi mtsogolo axially.
Kukula kwa Stone:Miyala ya abrasive imakula kwambiri ndi kukakamizidwa kolamuliridwa ndi khoma lamkati.
Kuchotsa Zinthu:Pamene chidacho chikuyenda, ma abrasives amachotsa malo okwera ndikuwongolera pamwamba.
➡ Themayendedwe ozungulira komanso obwerezabwerezaamapanga chikhalidwecrosshatch chitsanzo, kawirikawiri pa ngodya ya 30 -45 digiri.
Njirayi imatsimikizira kugawa bwino kwa filimu yamafuta ndi kusindikiza pisitoni yunifolomu.
Khwerero 4: Kuyeza ndi -Kuwongolera Kachitidwe
Advanced CNC honing machitidwe ntchitomu-njira yoyezerakuyeza bore diameter mosalekeza.
Kuthamanga kwa chakudya kapena kuthamanga kwa sitiroko kumasinthidwa kuti zikhalebe zolondola.
Khwerero 5: Kumaliza Pass
Mwala wonyezimira bwino kapena zida za diamondi zimagwiritsidwa ntchito kuti zithekepamwamba (Ra 0.1–0.4 µm)ndigeometry (kuzungulira Kuchepera kapena kofanana ndi 2 µm).
Gawo lomalizali likuwonetsetsa kuti silinda ikukumana ndi OEM kapena ISO.
Gawo 6: Kuyeretsa ndi Kuyang'anira
Pambuyo polima, bore ndikutsukidwa ndi zosungunulira kapena akupanga kuchapakuchotsa zotsalira zonse za abrasive.
Bore limayang'aniridwakuwongoka, m'mimba mwake, kuzungulira, taper, ndi kukhaula pamwambapogwiritsa ntchito ma air gauge kapena ma profelometer.
4. Zoyimira Honing Magawo a Hydraulic Cylinders
| Parameter | Mtundu Wofananira | Cholinga |
|---|---|---|
| Bore Diameter | 40 mm - 500 mm (wamba) | Mitundu ya silinda ya Hydraulic |
| Kuchotsa Zinthu Zofunika | 0.05 mm - 0.3 mm chonse | Kukula komaliza ndi kukonza |
| Crosshatch angle | 30 -45 digiri | Mulingo woyenera mafuta |
| Pamwamba Pamwamba (Ra) | 0.1–0.4 µm | Kuyenda kosalala kosalala |
| Kulekerera | ±1–3 µm | Kusindikiza mwatsatanetsatane |
| Honing Speed | 100-300 rpm kuzungulira / 10-30 m / min sitiroko | Kuchotsa zinthu moyenera |
| Honing Stones | Aluminium oxide / Silicon carbide / Diamondi / CBN | Zimatengera chubu kuuma |
5. Ubwino Wolemekeza Ma Cylinders a Hydraulic
Kusindikiza kwangwiropakati pa pisitoni ndi bore, kuonetsetsa kuti -imagwira ntchito mwaulere.
Kukangana kochepakwa kuyenda kosalala komanso kusamutsa mphamvu moyenera.
Kusungidwa bwino kwa filimu yamafutakuchepetsa kuwonongeka ndi dzimbiri.
Kuchepetsa phokoso ndi kugwedezekapa ntchito.
Utali wagawo moyondi kuchepetsa ndalama zosamalira.
Kugwirizana ndi zisindikizochifukwa cha mawonekedwe ake enieni komanso geometry.
Chidule
Popanga ma silinda olondola a hydraulic,kulemekeza ndikofunikakuti tikwaniritse kuphatikiza kwakulondola kwa dimensional, ungwiro wa geometric, komanso magwiridwe antchito apamwambazofunika pamakina-apamwamba amadzimadzi.
Popanda ulemu:
Kusindikiza kungakhale kosadalirika,
Kuwonongeka kwa mikangano kudzawonjezeka, ndipo
Kuchita kwa cylinder kungawonongeke kwambiri.
Choncho,makina opangira honing amasintha chubu chopangidwa ndi makina kukhala gawo lolondola kwambiri la hydraulicwokhoza kupereka magwiridwe antchito mokhazikika pansi pamavuto.
Mwachidule:
Zotopetsaamapatsa bore mawonekedwe ake.
Honingamazipatsa kuchita kwake.
