Uburyo bwa polishinge yububiko bwa plastike

Gukoresha imashini

Gukanika imashini nuburyo bwo gusya bushingiye ku gukata no guhindura plastike hejuru yubutaka kugirango ukureho ibice bya convex bisizwe kugirango ubone ubuso bunoze. Mubisanzwe, inkoni yamabuye yamavuta, ibiziga byubwoya, sandpaper, nibindi birakoreshwa, kandi ibikorwa byintoki nuburyo nyamukuru. Ibice byihariye nkubuso bwumubiri uzunguruka birashobora gukoreshwa. Ukoresheje ibikoresho byingirakamaro nkibishobora guhinduka, ultra-precision polishing irashobora gukoreshwa kubafite ubuziranenge bwibisabwa hejuru. Ultra-precision polishinge ni ugukoresha ibikoresho byihariye byo gukuramo, bigakanda cyane hejuru yubutaka bwatunganijwe mukazi kayo mumazi ya polishinge arimo abrasive kugirango azunguruke byihuse. Ukoresheje iri koranabuhanga, uburinganire bwubuso bwa Ra0.008μm burashobora kugerwaho, aribwo hejuru muburyo butandukanye bwo gusya. Amashanyarazi ya optique akoresha ubu buryo.

Gusiga imiti

Imiti ya chimique nugukora hejuru ya microscopique convex yibice bigize ibikoresho muburyo bwa chimique bishonga cyane kuruta igice cyegeranye, kugirango ubone ubuso bunoze. Inyungu nyamukuru yubu buryo nuko idasaba ibikoresho bigoye, irashobora gusiga ibihangano bifite ishusho igoye, kandi irashobora guhanagura ibihangano byinshi icyarimwe, hamwe nibikorwa byiza. Ikibazo nyamukuru cyo gusya imiti nugutegura amazi meza. Ubuso bwubuso bwabonetse kubwo gutunganya imiti muri rusange ni 10 mm.

Ihame ryibanze rya pololitiki ya electrolytike nimwe nkiya polishinge ya chimique, ni ukuvuga, muguhitamo gushonga uduce duto duto hejuru yibikoresho kugirango ibintu bishoboke. Ugereranije no gutunganya imiti, ingaruka za cathode reaction zirashobora kuvaho, kandi ingaruka nibyiza. Amashanyarazi yamashanyarazi agabanijwemo intambwe ebyiri: (1) Kuringaniza Macroscopique Ibicuruzwa byashonze bikwirakwizwa muri electrolyte, kandi ububobere bwa geometrike yubuso bwibintu buragabanuka, Ra> 1μm. Kuringaniza-urumuri ruto: Anode polarisiyasi, umucyo wubuso uratera imbere, Ra <1μm.

Ultrasonic polishing

Shira igihangano mu guhagarika abrasive hanyuma ubishyire hamwe mumurima wa ultrasonic, wishingikirije ku ngaruka zinyeganyega za ultrasonic, kugirango abrasive iba hasi kandi isukuye hejuru yakazi. Imashini ya Ultrasonic ifite imbaraga nkeya ya macroscopique kandi ntabwo izatera guhindura imikorere yakazi, ariko biragoye gukora no gushiraho ibikoresho. Gutunganya Ultrasonic birashobora guhuzwa nuburyo bwa chimique cyangwa amashanyarazi. Hishimikijwe ibisubizo byangirika hamwe na electrolysis, vibrasi ya ultrasonic ikoreshwa kugirango ikangure igisubizo, kugirango ibicuruzwa byashonze hejuru yumurimo wakazi biratandukana, kandi ruswa cyangwa electrolyte hafi yubuso birasa; Ingaruka ya cavitation ya ultrasonic mumazi irashobora kandi kubuza inzira yo kwangirika no koroshya ubuso.

Amazi yo kwisiga yishingikiriza kumuvuduko mwinshi utemba wamazi nuduce twinshi tuyitwara kugirango woze hejuru yakazi kugirango ugere ku ntego yo gusya. Uburyo bukunze gukoreshwa ni: gutunganya indege, gutunganya indege, gusya hydrodynamic nibindi. Gusya Hydrodinamike itwarwa nigitutu cya hydraulic kugirango igikoresho cyamazi gitwara uduce duto twa abrasive kigenda gisubira inyuma hejuru yumurimo wihuse. Ikigereranyo gikozwe cyane cyane mubintu bidasanzwe (ibintu bisa na polymer) bifite umuvuduko mwiza munsi yumuvuduko muke kandi bivanze na abrasives. Abrasives irashobora kuba ikozwe mu ifu ya silicon karbide.

Gusya kwa rukuruzi no gusya

Magnetic abrasive polishing nugukoresha magnetiki abrasives kugirango ukore ibishishwa byangiza munsi yumurimo wa magneti kugirango usya akazi. Ubu buryo bufite uburyo bunoze bwo gutunganya, ubuziranenge bwiza, kugenzura byoroshye uburyo bwo gutunganya nibikorwa byiza. Ukoresheje ibishishwa bikwiye, uburinganire bwubuso bushobora kugera kuri Ra0.1μm. 2 Gukoresha imashini zishingiye kuri ubu buryo Amashanyarazi avugwa mugutunganya ibishushanyo bya plastike aratandukanye cyane no gusya hejuru bisabwa mu zindi nganda. Mu magambo make, gusiga ibishushanyo bigomba kwitwa gutunganya indorerwamo. Ntabwo ifite ibisabwa byinshi byo kwisiga ubwayo, ahubwo ifite n'ibipimo bihanitse byo hejuru yuburinganire, ubworoherane hamwe na geometrike. Ubuso bwo hejuru busaba gusa ubuso bwiza. Ibipimo byo gutunganya indorerwamo bigabanijwe mubice bine: AO = Ra0.008μm, A1 = Ra0.016μm, A3 = Ra0.032μm, A4 = Ra0.063μm. Biragoye kugenzura neza neza geometrike yibice bitewe nuburyo nka electrolytike polishing na fluid polishing. Nyamara, ubwiza bwubuso bwa polishike ya chimique, ultrasonic polishing, magnetic abrasive polishing nubundi buryo ntabwo bujyanye nibisabwa, bityo gutunganya indorerwamo yibibumbano byuzuye biracyari cyane cyane.
