Munzvimbo dzakasiyana-siyana dzekugadzira zvinhu mumaindasitiri, rabha roller chinhu chakakosha chose. Chinowanikwa mune zvese kubva mumichina yekudhinda inokurumidza uye michina ye laminating kusvika kumitsetse yekugadzira simbi uye ma copiers emahofisi, mashandiro erabha roller anoenderana nemhando yenzvimbo yacho. Kunyange zvazvo roller inogona kuumbwa uye kuvharwa nemazvo, mugadziri we roller wekuChina, ndiyo danho rekupedzisira rekupedzisa - kunyanya, kupukuta - rinosimudzira chikamu chinoshanda kuita chishandiso chakanyatsojeka. Muchina we rabha roller polishing ndiwo mudziyo wakagadzirirwa basa iri guru, mugadziri we rabha roller, unoshandiswa kana standard of surface roughness (Ra) ichida kutsetseka kwakakwana.
Chinangwa: Kuoma Kwepamusoro Uye Zvazvinoreva
Kukweshana kwepamusoro hakusi kungoyera runako chete; ipfungwa inoshanda inodzora mashandiro anoita roller munzvimbo yayo. Mumashandisirwo akadai sekugadzira zvishandiso zvekurapa, kugadzira mafirimu emaziso, kana kudhinda kwepamusoro-soro, kunyangwe kusakwana kudiki-diki pamusoro peroller kunogona kushandura kuva zvikanganiso zvikuru.
Kana zvinodiwa zvichidikanwa kuti huremu hwepamusoro huve pasi pe0.2 Ra (micrometers) kana kutosvika pa sub-micron range, kukuya kwakajairika hakuna kukwana. Kukuya kunosiya magumo akajeka, asina kujeka anozivikanwa ne peaks nema valleys madiki. Muchina wekupukuta unoshandiswa kutetepa peaks idzi, zvichiita kuti pamusoro padzo pave panyoro uye pave pasina makemikari akawanda uye pasabatana nezvinhu. Kune maroller anoshandiswa mu silicone kana urethane applications—apo kunamira kunogona kukonzera kuputika kwewebhu mukudhinda kana kuputira—nzvimbo yakakwenenzverwa inoita kuti pave nekusunungurwa kwakachena uye kugadzikana nguva dzose.
Maitiro: Kubva pakucheka nehasha kusvika pakupisa pamusoro
Muchina wekupukuta werabha unotenderera wakasiyana zvikuru newakajairika wekupukuta wecylindrical. Kunyange zvazvo muchina wekupukuta uchishandisa vhiri rekukuya rakaomarara, rinomhanya zvakanyanya kubvisa zvinhu uye kuita kuti zvive zvakanaka, muchina wekupukuta unoshanda nepfungwa yekukweshana kwakadzora uye kukweshana kudiki.
Michina yemazuva ano yekupolisha inowanzova nemubhedha we lathe une musoro wakanyatsogadzirwa uye tailstock yekutsigira roller. Chinhu chakakosha ruoko rwekupolisha kana ngoro, iyo inobata abrasive media. Kusiyana nekukuya, uko vhiri rakaoma kupfuura workpiece, rabha yekupolisha inoda kuyera kumhanya, kumanikidzwa, uye abrasive grit zvakanyatsonaka.
Maitiro acho anowanzo pfuura nepakati pematanho akawanda:
1. Kupukuta Pamberi (Kutsvedzerera): Kutanga nemabhandi kana matombo ane grit yepakati (kazhinji grit inosvika 400 kusvika 800) kubvisa mavanga anotenderera anosara panguva yekukuya. Danho iri rinovimbisa kuenderana kwejometri.
2. Kupukuta Kwakanaka: Kuchinja kuita mafirimu ekukwesha ane grit yakakwira (grit 1500 kusvika 3000) kana mabrasive asina kurukwa enylon akazadzwa nezvidimbu zvidiki. Muchina wekupukuta wakanaka, Padanho rino, muchina unoderedza kukosha kweRa zvakanyanya, uchienda kumagumo akajeka zvishoma.
3. Kupedzisa Zvakanyanya (Kupisa): Kuti zvive zvakakosha (kujekesa kwemaziso kana kuti sub-1 Ra values), muchina unogona kushandisa machira ekupukuta akasarudzika kana tambo dzefelt dzakazadzwa nedhaimani rakapfava zvakanyanya kana kuti zvinhu zvine mvura. Padanho rino, maitiro acho haasi ekubvisa zvinhu asi ekuti "kupomba" pamusoro perabha kuti uvhare maburi madiki uye kubvisa zvachose magadzirirwo enzira.
Michina yemazuva ano inosanganisira zvinhu zvakaita semisoro inokwenya inotenderera kudzivirira kuumbwa kwemhete dzakatenderedza, madhiraivha anochinja-chinja ekudzora tsoka dzepamusoro paminiti (SFM), uye masensa emagetsi ekudzivirira kuti ave nechokwadi chekuti tambo dzinobata zvakanaka pahurefu hwechiso cheroller.
Basa Mukupedzisa
Muhurongwa hwekugadzira maroller, kupolisha kunomiririra gedhi remhando yepamusoro. Mushure mekunge roller yaumbwa, yagadziriswa (yerabha), kana kuti yagadziriswa (yepolyurethane), inotenderedzwa zvine hunyanzvi uye yozogayiwa nemazvo kuti isvike padhayamita chaiyo uye ikwanise kugadzikana. Zvisinei, kugayiwa kunowanzo shanda - kuomesa pamusoro perabha kana kugadzira "kukurunga".
Muchina wekupukuta unoita mabasa matatu akakosha ekupedzisa:
· Kubvisa Geometry kubva paMagadzirirwo: Kunyange zvazvo muchina wekukuya uchiraira kutenderera uye dhayamita, mupolishi unoraira magadzirirwo pasina kuchinja geometry.
· Kucheneswa Kwemucheto: Kune maroller ane maburi kana migero, michina yekupolisha ine kugona kupolisha inogona kupolisha zviso nemipendero kudzivirira maburi akapinza anogona kukuvadza mawebhu kana mafirimu anonzwa.
· Kuenderana kwezvinhu: Ma elastomer akasiyana anoita zvakasiyana nekupisa. Michina yekupolisha inomhanya nekumhanya kwakaderera ine nzira dzekutonhodza (mhepo kana mvura inotonhodza) kudzivirira kupisa kunokonzerwa nekukweshana kubva pakuzvimba kwerabha kana kupwanya polyurethane binders.
Kugadziriswa kweMichina uye Kuzvigadzira Otomatiki
Kuomarara kwemuchina wekupukuta werabha unotenderera kunosiyana zvichienderana nekushandiswa kwawo.
· Manual Lathe-Based Polishers: Anowanikwa muzvitoro zvidiki kana munzvimbo dzekugadzirisa, aya anovimba nehunyanzvi hwemushandisi wekuisa mabhandi anokwenya nemaoko pa roller inotenderera. Kunyange zvazvo asingadhuri, haachinji pabasa rakanyatsojeka.
· Nzvimbo Dzekupolisha dzeCNC: Pakugadzira zvinhu zvine huwandu hwakawanda kana kuti zvakanyatsonaka, nzvimbo dzekupolisha dzeCNC (Computer Numerical Control) ndidzo dzakajairika. Michina iyi inochengeta mabikirwo ekupedzisa, inochinja otomatiki magrits abrasive, uye inochengetedza kumanikidzwa kwakatwasuka pamusoro pekorona yeroller. Inokosha kune maroller ane ma profiles akaomarara (ane korona, akakombama, kana akatsikwa) uko kupolisha nemaoko kunogona kukanganisa chimiro cheinjiniya.
· Zvinonamirwa pakugadzira zvinhu zvinopenya: Mamwe mabasa anoshandisa misoro inopenya inosanganisa oscillation ne high-pressure coolant kuti iite "cross-hatch" pattern, kunyange zvazvo pagirazi rakachena rinopedzwa parabha, nzira ye felt-and-paste inoramba iriyo yakajairika.
Zvakanakira uye Zvisina Kukwana
Chinhu chikuru chinobatsira pakushandisa muchina wekupukuta wakagadzirirwa nderekuti uve nechinhu chisina kuremara, chakaita segirazi chinoderedza kukweshana uye chinowedzera simba rekuburitsa zvinhu. Kune maindasitiri akaita sekudhinda kweflexographic, roller inopukutwa inoita kuti inki ifambiswe zvakanaka; pakuisa laminating, inodzivirira kuungana kwezvimedu zvinonamatira.
Zvisinei, pane zvipingamupinyi. Kupolisha inzira yekubvisa zvinhu zvishoma. Kana chifukidziro cherabha chakatetepa, kana mushandisi akapolisha zvine simba kubvisa dambudziko rakadzika, dhayamita yeroller inogona kudonha isingakwiridzike. Uyezve, haasi ese macompounds erabha anopolisha zvakaenzana. Maroller edurometer akapfava (ari pasi pe40 Shore A) anozivikanwa nekuoma kupolisha, kugadzira rabha, sezvo anowanzo "kuungana" pasi pekumanikidzwa kwakasimba, nepo maurethane akaomarara uye macompounds eEPDM anogona kuita girazi rakaita serinopera.
Mhedziso
Muchina wekupukuta werabha hausi chinhu chekupedzisa zviri nyore; ndiwo muganho uripo pakati pekugadzirisa zvinhu nemazvo uye mashandiro azvo. Munguva ino apo kushivirira kwekugadzira zvinhu kuri kudzikira uye zvinodiwa zvemhando yepamusoro zviri kuwedzera—kunyanya muzvikamu zvemagetsi, zvekurapa, uye zvekurongedza—kukwanisa kudzora kushata kwepamusoro padanho diki inyaya yakanaka yekukwikwidzana.
Nekubatanidza tekinoroji yepamusoro yekukwesha nekudzora kwakanyatsojeka kwemichina, michina iyi inoita kuti roller yerabha isangosviki pahukuru hwayo chete, asi ishande zvakanaka mumamiriro ezvinhu akaomarara ekugadzirwa kwemaindasitiri nekukurumidza uye zvine njodzi. Ingave roller yesimbi inoda kupfava kusingaparadzike kana roller yeprinta inoda kugoverwa kweinki isina mhosva, muchina wekupolisha unopa kugona kwekupedzisira, kwakakosha.
