Popanga zazibowo za silinda zamagalimoto, njira yopangira honing ndiyofunikira kuti mukwaniritse zofunikirakulondola, kumaliza pamwamba,ndikulondola kwa geometric. Makina opangira honing amagwira ntchito yofunika kwambiri pakuyenga pamwamba pa silinda kuti akwaniritse zofunikira pakuchita bwino kwa injini, kuchita bwino, komanso moyo wautali.
Chifukwa chiyani aHoning MachineChofunika:
Ma cylinder bores ndi zinthu zofunika kwambiri mu injini, chifukwa zimayika ma pistoni ndipo ziyenera kupereka malo olondola, osalala kuti ma pistoni azitha kuyenda. Pakupanga, ma cylinder bores amapangidwa kudzera munjira ngatiwotopetsakapenakubowola. Ngakhale njirazi zimapanga mawonekedwe a silinda, sizimapereka mapeto omaliza ofunikira kuti pisitoni iyende bwino, kusunga mafuta, komanso kukana kuvala. Apa ndipamene makina opangira honing amayamba.
Themakina osindikizirandikofunikira kwa:
Kukwaniritsa Zolondola: Zobowola za silinda ziyenera kukhala zozungulira ndendende, zozungulira, ndi zowongoka, makamaka zamainjini othamanga kwambiri-. Makina a Honing amapereka zosintha zabwino zofunika kuti zitsimikizire kuti silinda imakumana ndi kulolerana kolimba.
Kupanga Malo Oyenera Kumaliza: M'kati mwa cylinder bore iyenera kukhala ndi mawonekedwe apadera omwe amalimbikitsa kusindikiza koyenera pakati pa mphete za pistoni ndi khoma la silinda. Iyeneranso kulola kusungidwa bwino kwa mafuta kuti muchepetse mikangano ndi kuvala.
Kupititsa patsogolo Kukhulupirika kwa Geometrical: Kachitidwe kakupeta kamathandizira kuchotsa zolakwika zilizonse monga-zozungulira{1}}zozungulira, zokhotakhota, kapena kupotoza komwe kumachitika chifukwa cha m'mbuyomu, kuwonetsetsa kuti pali zowona, zofanana.
Ntchito ya Honing Machine:
Kumaliza Pamwamba: Honing amachotsa pang'ono zinthu pa bore kuti patsogolo pamwamba mapeto, amene makamaka amafuna kukwaniritsa roughness pamwamba osiyanasiyanaRa 0.2 mpaka 1.0 microns(malingana ndi mawonekedwe a injini). Kusalalako kumapangitsa kuti mphete za pistoni zitseke bwino.
Kukula ndi Kulekerera Kuwongolera: Makina opangira ma honing amagwiritsidwa ntchito kuti akwaniritse chomaliza, cholondola m'mimba mwake mwa cylinder bore, kuonetsetsa kuti chikugwirizana ndi pisitoni ndikupereka kuponderezedwa koyenera.
Kuzungulira ndi Kuwongoka: Njira yopangira honing imatsimikizira kuti silinda ya silinda imakhala yozungulira komanso yowongoka, ndikuchotsa zosagwirizana zilizonse pamakina am'mbuyomu.
Chithunzi cha Crossshatch: Honing kumapanga mwachindunjicrosshatch chitsanzopamwamba pa chibowo, chomwe chiri chofunikira kuti mafuta asungidwe. Chitsanzochi chimathandizira kupanga chisindikizo choyenera ndi mphete za pistoni ndikuchepetsa kuvala pakhoma la silinda ndi mphete za pistoni.
Deburring: Njira yopangira honing imathandizira kuchotsa ma burrs kapena m'mbali zakuthwa zomwe zatsala pamasitepe am'mbuyomu, ndikuwongolera mawonekedwe onse a silinda.
Momwe Honing process imachitikira:
Kukonzekera:
Bore la silinda limayamba kupangidwa mokulira movutikira pogwiritsa ntchito njira zotopetsa kapena kubowola.
Chogwirira ntchito (silinda block) chimayikidwa bwino pamakina a honing.
Makina owongolera ali nawomiyala ya abrasivekapenamalamba abrasivezomwe zimasankhidwa mwachindunji kutengera kumaliza komwe kufunidwa ndi zinthu zakuthupi za silinda.
Kukonzekera kwa Chida cha Honing:
Abrasive Stones: Miyala iyi idayikidwapokumeta mituzomwe zimazungulira mkati mwa cylinder bore. Nthawi zambiri miyalayi imapangidwaaluminium oxidekapenakiyubiki boron nitride (CBN), malingana ndi kuuma kwa zinthu.
Stroke Mechanism: Chida cha honing chimasunthidwa mobwerezabwereza (kumbuyo-ndi-kutsogolo) mkati mwa bore. Kuyenda uku, pamodzi ndi kusinthasintha kwa miyala yonyezimira, kumatsimikizira kuti pamwamba ndi ntchito yofanana.
Kupaka mafuta: Madzi apadera odulira kapena ozizira amagwiritsidwa ntchito kupaka mafuta, kuchepetsa kutentha komanso kupewa kuvala kwa abrasive. Zimathandizanso kunyamula zinthu zabwino zomwe zachotsedwa pabowo.
Honing Process:
Kukula kwa Radial kwa Abrasive Stones: Pamene honing chida chimayenda, ndimiyala ya abrasivekapenamaburashi abrasivekanikizani chakunja ku khoma la silinda, pang'onopang'ono kugaya ndi kupukuta pobowolo. Kupanikizika komwe kumachitika nthawi zambiri kumakhala kotsika kuonetsetsa kuti zinthu zachotsedwa bwino popanda kuwononga pamwamba.
Zosintha Zosintha: Wothandizira amasintha magawo ofunika ngatiliwiro lozungulira, kugunda kwa mtima,ndim'mimba mwake kukula kwa miyalakuti mukwaniritse zofunikira, geometry, ndi kukula kwake.
Chithunzi cha Crossshatch: Panthawi yoweta, kusuntha kwa miyala ya abrasive ndi kuzungulira kwa silinda kumapangacrosshatch chitsanzopamwamba. Njira iyi ndiyofunikira pakuwongolera kusungidwa kwamafuta ndikuwonetsetsa kusindikizidwa koyenera pakati pa mphete za pistoni ndi khoma la silinda.
Miyezo Yomaliza:
Them'mimba mwake ya silindaimayesedwa nthawi yonseyi kuti zitsimikizire kuti kukula kwake komaliza kumafanana ndi zomwe zimafunikira. Thekuzungulirandikuwongokaza bore nazonso zimatsimikiziridwa.
Kumapeto kwapamwamba kumawunikiridwa, nthawi zambiri kudzera mu ma profilometers, kuti atsimikizire kuti akugwera mkati mwazovuta komanso zopingasa.
Kumaliza:
Pamene ankafuna pamwamba mapeto ndi kulolerana dimensional zimatheka, ndi honing ndondomeko anasiya.
Chotchinga cha silinda chimachotsedwa mu makina opangira honing ndikutsukidwa kuti muchotse zinyalala zilizonse ndi zotsalira zoziziritsa kukhosi.
Chidule cha ndondomeko ya Honing:
Makina Ovuta: Mabomba a Cylinder amapangidwa potopetsa kapena kubowola.
Khazikitsa: Ntchitoyi imayikidwa pamakina opangira honing, ndipo miyala ya abrasive kapena maburashi imayikidwa.
Honing: Chidachi chimayenda mozungulira ndikubwezeretsanso mkati mwa bore, kuchotsa zinthu zazing'ono kuti ziwongolere kuzungulira, kukula, ndi kutha kwa pamwamba.
Kupanga Chitsanzo: Patani yopingasa imapangidwa pamwamba, yomwe ndiyofunikira kuti mafuta asungidwe komanso pisitoni yoyenera-kusindikiza mphete.
Miyezo Yomaliza ndi Kuyeretsa: Bore limayezedwa kuti zitsimikizire kuti zonse zakwaniritsidwa, ndipo gawolo latsukidwa kuti lisonkhanitsidwenso.
Chifukwa Chake Honing Ndikofunikira:
Kulondola: Njira yopangira honing imakwaniritsa kulondola komwe kumafunikira kuti pakhale kolimba pakati pa pisitoni ndi bore la silinda.
Ubwino Wapamwamba: Mawonekedwe osalala, ophatikizika opangidwa ndi honing amatsimikizira kuti mphete za pistoni zimatha kusindikiza bwino komanso kuti khoma la silinda limathiridwa mafuta bwino.
Kukhalitsa: Honing imapangitsa kulimba kwa silinda mwa kukonza kutha kwake komanso geometry, kuchepetsa kuvala kwa mphete za silinda ndi pistoni pakapita nthawi.
Kuchita bwino kwa Injini: Kukonza koyenera kumapangitsa kuti injini ikhale yogwira bwino ntchito, mphamvu, ndi kuchepetsa kugwiritsa ntchito mafuta, zomwe zimapangitsa kuti{0}}injini igwire ntchito kwanthawi yayitali.
