Jigon da aiwatar da goge goge
Me yasa muke buƙatar yin aikin sarrafa ƙasa akan sassa na inji?
Tsarin jiyya na saman zai zama daban-daban don dalilai daban-daban.
1 Hanyoyi guda uku na sarrafa saman sassa na inji:
1.1 Hanyar sarrafa saman don samun daidaiton sashi
Don ɓangarorin da suka dace da buƙatun, buƙatun don daidaito (gami da daidaiton ƙima, daidaiton siffar har ma da daidaiton matsayi) yawanci suna da tsayi sosai, kuma daidaito da ƙaƙƙarfan saman suna da alaƙa.Don samun daidaito, dole ne a cimma madaidaicin taurin.Misali: daidaito IT6 gabaɗaya yana buƙatar daidaitaccen rashin ƙarfi Ra0.8.
[Ma'anar inji na gama gari]:
- Juyawa ko niƙa
- Lafiya m
- nika mai kyau
- Nika
1.2 Hanyoyin sarrafa saman don samun kayan aikin injiniya
1.2.1 Samun juriya
[Hanyoyin gama gari]
- Nika bayan hardening ko carburizing / quenching (nitriding)
- Nika da goge bayan wuya chrome plating
1.2.2 Samun kyakkyawan yanayin damuwa na saman
[Hanyoyin gama gari]
- Modulation da niƙa
- Maganin zafin jiki da niƙa
- Juyawa saman saman ko harbin leƙen asiri yana biye da niƙa mai kyau
1.3 Hanyoyin sarrafawa don samun kaddarorin sinadarai na saman
[Hanyoyin gama gari]
- Electroplating da polishing
2 Fasahar goge saman ƙarfe na ƙarfe
2.1 Muhimmanci Yana da wani muhimmin ɓangare na filin fasaha da aikin injiniya, kuma ana amfani dashi sosai a cikin tsarin samar da masana'antu, musamman a masana'antar lantarki, shafi, anodizing da matakai daban-daban na jiyya.
2.2 Me yasa sigogin saman farko da ma'aunin tasirin da aka samu na aikin aikin ke da mahimmanci?Domin su ne wuraren farawa da manufa na aikin polishing, wanda ke ƙayyade yadda za a zabi nau'in na'ura mai gogewa, da kuma adadin kawuna, nau'in kayan aiki, farashi, da ingancin da ake bukata don na'urar gogewa.
2.3 Nika & Matakan gogewa da Hanyoyi
Matakan gama gari guda huɗu naniƙakumapolishing ]: bisa ga farkon da na ƙarshe roughness Ra dabi'u na workpiece, m nika - lafiya nika - lafiya nika - polishing.Abrasives sun bambanta daga m zuwa lafiya.Dole ne a tsaftace kayan aikin niƙa da kayan aiki a duk lokacin da aka canza su.
2.3.1 The nika kayan aiki ne mafi wuya, da micro-yanke da extrusion sakamako ne mafi girma, da kuma girman da roughness da bayyananne canje-canje.
2.3.2 Mechanical polishing ne mafi m yankan tsari fiye da nika.Ana yin kayan aikin gogewa da kayan laushi, wanda kawai zai iya rage rashin ƙarfi amma ba zai iya canza daidaiton girman da siffar ba.Tsayinsa na iya kaiwa ƙasa da 0.4μm.
2.4 Ra'ayoyi guda uku na jiyya ta ƙarewa: niƙa, gogewa, da ƙarewa
2.4.1 Concept na inji nika da polishing
Ko da yake duka injin niƙa da polishing na inji na iya rage ƙarancin ƙasa, akwai kuma bambance-bambance:
- 【Mechanical polishing】: Ya hada da juriya juzu'i, siffar juriya da matsayi haƙuri.Dole ne ya tabbatar da juriyar juzu'i, juriya na siffa da juriya na matsayi na ƙasa yayin da yake rage rashin ƙarfi.
- Gyaran injina: Ya bambanta da gogewa.Yana inganta ƙarewar ƙasa kawai, amma ba za a iya ba da tabbacin haƙuri ba.Haskensa ya fi girma da haske fiye da gogewa.Hanyar gama gari na goge goge na inji shine niƙa.
2.4.2 [Kammala aiki] ne mai nika da polishing tsari (takaice a matsayin nika da polishing) da za'ayi a kan workpiece bayan m machining, ba tare da cire ko kawai cire wani bakin ciki Layer na abu, tare da babban manufar rage surface roughness. yana kara sheki da kuma karfafa shimfidarsa.
Daidaitacce da rashin ƙarfi na ɓangaren ɓangaren suna da tasiri mai girma akan rayuwarsa da ingancinsa.Lalacewar Layer da EDM ya bari da ƙananan ƙwayoyin da aka bari ta hanyar niƙa zai shafi rayuwar sabis na sassan.
① Tsarin kammalawa yana da ƙaramin izinin machining kuma ana amfani dashi galibi don haɓaka ingancin ƙasa.Ana amfani da ƙaramin adadin don inganta daidaiton injina (kamar daidaiton girma da daidaiton siffar), amma ba za a iya amfani da shi don inganta daidaiton matsayi ba.
② Ƙarshe shine aiwatar da ƙananan yankewa da kuma fitar da saman aikin aiki tare da abrasives masu kyau.Ana sarrafa farfajiyar daidai gwargwado, yankan karfi da yanke zafi kadan ne, kuma ana iya samun inganci mai inganci sosai.③ Ƙarshe tsari ne na ƙarami kuma ba zai iya gyara lahani mafi girma ba.Dole ne a yi aiki mai kyau kafin sarrafawa.
Jigon karfe surface polishing ne surface zabe micro-cire aiki.
3. A halin yanzu balagagge polishing tsari hanyoyin: 3.1 inji polishing, 3.2 sinadaran polishing, 3.3 electrolytic polishing, 3.4 ultrasonic polishing, 3.5 ruwa polishing, 3.6 Magnetic nika polishing,
3.1 Gyaran injina
Gyaran injina hanya ce mai gogewa wacce ta dogara da yankan da nakasar filastik na saman kayan don cire abubuwan da aka goge don samun fili mai santsi.
Amfani da wannan fasaha, inji polishing iya cimma wani surface roughness na Ra0.008μm, wanda shi ne mafi girma a tsakanin daban-daban polishing hanyoyin.Ana amfani da wannan hanyar sau da yawa a cikin ƙirar ruwan tabarau na gani.
3.2 Chemical goge
gyare-gyaren sinadarai shine sanya ƙananan sassa na saman abu su narke da kyau a cikin sinadari akan sassan sassa, ta yadda za'a sami wuri mai santsi.Babban fa'idodin wannan hanya shine cewa baya buƙatar kayan aiki masu rikitarwa, yana iya goge kayan aiki tare da sifofi masu rikitarwa, yana iya goge kayan aiki da yawa a lokaci guda, kuma yana da inganci sosai.Babban batu na gogewar sinadarai shine shirya ruwa mai gogewa.Ƙunƙarar saman da aka samu ta hanyar gogewa sinadarai gabaɗaya dubun μm ne.
3.3 Electrolytic polishing
Electrolytic polishing, wanda kuma aka sani da electrochemical polishing, zaɓen yana narkar da ƴan ƴan ɗimbin gyare-gyare a saman kayan don yin santsi.
Idan aka kwatanta da sinadaran polishing, sakamakon cathode dauki za a iya kawar da kuma sakamako ne mafi alhẽri.Tsarin polishing electrochemical ya kasu kashi biyu matakai:
(1) Matsayin macro: Abubuwan da aka narkar da su suna bazuwa a cikin electrolyte, kuma ƙarancin juzu'i na saman kayan yana raguwa, Ra 1μm.
(2) Gloss smoothing: Anodic polarization: An inganta hasken saman, Ralμm.
3.4 Ultrasonic polishing
The workpiece da aka sanya a cikin wani abrasive dakatar da kuma sanya shi a cikin wani ultrasonic filin.The abrasive ne ƙasa da goge a kan workpiece surface ta oscillation na ultrasonic kalaman.Ultrasonic machining yana da ƙananan macroscopic ƙarfi kuma ba zai haifar da nakasawa na workpiece ba, amma kayan aiki yana da wuyar ƙira da shigarwa.
Ana iya haɗa mashin ɗin ultrasonic tare da hanyoyin sinadarai ko na lantarki.A kan tushen da bayani lalata da electrolysis, ultrasonic vibration ake amfani da su motsa bayani don raba narkar da kayayyakin a kan workpiece surface da yin lalata ko electrolyte kusa da surface uniform;da cavitation sakamako na ultrasonic taguwar ruwa a cikin ruwa kuma iya hana lalata tsari da kuma sauƙaƙe surface haskakawa.
3.5 Gyaran ruwa
Gyaran ruwa ya dogara da ruwa mai saurin gudu da kuma barbashi da yake ɗauka don goge saman aikin don cimma manufar gogewa.
Hanyoyin da aka fi amfani da su sun haɗa da: sarrafa jet na abrasive, sarrafa jet na ruwa, niƙa mai ƙarfi, da sauransu.
3.6 Magnetic niƙa da goge baki
Magnetic niƙa da polishing yana amfani da Magnetic abrasives don samar da abrasive goge a karkashin aikin wani Magnetic filin don nika workpiece.
Wannan hanyar tana da ingantaccen aiki mai inganci, inganci mai kyau, sauƙin sarrafa yanayin sarrafawa, da kyakkyawan yanayin aiki.Tare da abrasives masu dacewa, ƙarancin saman zai iya kaiwa Ra0.1μm.
Ta wannan labarin, na yi imani za ku sami kyakkyawar fahimtar gogewa.Daban-daban iri polishing inji zai ƙayyade sakamako, yadda ya dace, kudin da sauran Manuniya na cimma daban-daban workpiece polishing raga.
Wani nau'in na'ura mai gogewa da kamfanin ku ko abokan cinikin ku ke buƙata ba kawai a daidaita shi bisa ga aikin da kansa ba, har ma dangane da buƙatun kasuwa na mai amfani, yanayin kuɗi, haɓaka kasuwanci da sauran dalilai.
Tabbas, akwai hanya mai sauƙi da inganci don magance wannan.Da fatan za a tuntuɓi ma'aikatan mu kafin siyarwa don taimaka muku.
