Mahombe, matete-madziro ane madziro eshe ari nyore kuchinjika nekuremara panguva yekugadzira. Muchikamu chino, isu tichaunza kupisa sink kesi yezvikamu zvakakura uye zvitete-madziro kuti tikurukure matambudziko ari mugadziro machining process. Pamusoro pezvo, isu tinopawo yakagadziridzwa maitiro uye fixture mhinduro. Ngatisvike pazviri!
Iyo kesi ndeye chikamu chegoko chakagadzirwa neAL6061-T6 zvinhu. Heano maitiro ayo chaiwo.
Zvose Dimension: 455 * 261.5 * 12.5mm
Tsigira Rusvingo Ukobvu: 2.5mm

Dzidzira uye Matambudziko Munzira Dzakasiyana-siyana
Munguva yeCNC machining, aya akatetepa-akakomberedzwa magoko zvimiro zvinowanzokonzera huwandu hwematambudziko, senge warping uye deformation. Kuti tikunde nyaya idzi, tinoedza kupa serval process nzira sarudzo. Nekudaro, kuchine zvimwe chaizvo nyaya kune yega yega maitiro. Hedzino udzame.
Nzira yeKugadzira 1
Mukuita 1, tinotanga nekugadzira reverse side (yemukati side) yeworkpiece tozoshandisa plaster kuzadza nzvimbo dzakavhurika. Tevere, tichirega reverse side rive referensi, tinoshandisa glue uye kaviri-side tepi kugadzirisa referensi divi panzvimbo kuitira kuti muchina kumberi divi.
Zvisinei, kune mamwe matambudziko nenzira iyi. Nekuda kweiyo hombe yekumashure yakazadzwa nzvimbo padivi reshure, glue uye kaviri-mativi tepi haina kunyatso chengetedza workpiece. Zvinotungamirira warping pakati workpiece uye zvakawanda zvinhu kubviswa ari muitiro (inonzi overcutting). Uye zvakare, kushaikwa kwekugadzikana kweiyo workpiece kunotungamirirawo kune yakaderera kugadzirisa kushanda uye yakashata pamusoro pebanga maitiro.
Nzira Yekuita 2
Mukuita 2, tinoshandura kurongeka kwekugadzira. Tinotanga nechepasi (kurutivi uko kupisa kunopera) uye toshandisa purasita yekudzosera kumashure kwenzvimbo isina mhango. Tevere, tichirega divi remberi sereferensi, tinoshandisa glue uye kaviri-mativi tepi kuti tigadzirise referensi divi kuti isu tishande reverse side.
Nekudaro, dambudziko rekuita uku rakafanana nekuita nzira 1, kunze kwekunge nyaya yacho ichichinjirwa kune reverse side (mukati memukati). Zvakare, kana rutivi rwekumashure ruine nzvimbo yakakura yekudzosera kumashure, kushandiswa kweglue uye tepi ine mativi maviri haipe kugadzikana kwepamusoro kune workpiece, zvichikonzera warping.
Nzira Yekuita 3
Mukuita 3, tinofunga kushandisa machining sequence ye process 1 kana process 2. Zvino muchikamu chechipiri chekutsanya, shandisa ndiro yekudhinda kuti ubate workpiece nekutsikirira pasi perimita.
Zvisinei, nekuda kwenzvimbo yakakura yechigadzirwa, platen inongokwanisa kuvhara nzvimbo yeperimeter uye haigoni kugadzirisa zvakakwana nzvimbo yepakati ye workpiece.
Kune rumwe rutivi, izvi zvinoguma munzvimbo yepakati yeworkpiece ichiri kuoneka kubva kuhondo uye deformation, izvo zvinozoita kuti kuwedzeredza mukati menzvimbo yechigadzirwa. Kune rimwe divi, iyi machining nzira ichaita kuti dzakatetepa-yakakomberedzwa CNC goko zvikamu kushaya simba.
Nzira Yekuita 4
Mukuita 4, isu tinogadzira reverse side (yemukati side) kutanga tozoshandisa vacuum chuck kubatanidza iyo machined reverse ndege kuitira kushanda kumberi.
Nekudaro, kana iri yechikamu chakatetepa-chakakomberedzwa negoko, kune concave uye convex zvimiro kudivi reshure reworkpiece iyo yatinofanira kudzivirira kana tichishandisa vacuum suction. Asi izvi zvinogadzira dambudziko idzva, nzvimbo dzakadzivirirwa dzinorasikirwa nesimba rekusveta, kunyanya munzvimbo ina dzemakona pane denderedzwa reiyo yakakura mbiri.
Sezvo nzvimbo idzi dzisina kunyudzwa dzichienderana nedivi rekumberi (iyo yakashongedzerwa pamusoro panguva ino), iyo yekucheka chishandiso inogona kuitika, zvichikonzera kuvibrating chishandiso pateni. Nokudaro, nzira iyi inogona kuva nemigumisiro yakaipa pahutano hwekugadzira uye kupera kwepamusoro.
Optimized Process Route uye Fixture Solution
Kuti tigadzirise matambudziko ari pamusoro, isu tinokurudzira inotevera optimized process uye fixture mhinduro.
Pre-machining Screw Through-makomba
Chekutanga, takavandudza nzira yekugadzira. Nemhinduro nyowani, isu tinogadzira iyo reverse side (yemukati divi) kutanga uye pre-muchina screw kuburikidza-buri mune dzimwe nzvimbo dzinozopedzisira dzavharwa kunze. Chinangwa cheizvi ndechekupa nzira iri nani yekugadzirisa uye kuisa nzira mumatanho anotevera ekugadzira.
Denderedzwa Nzvimbo Ichagadzirwa
Tevere, isu tinoshandisa ndege dzakagadzirwa kudivi reshure (mukati memukati) senge machining reference. Panguva imwecheteyo, tinochengetedza workpiece kuburikidza nekupfuura screw kuburikidza ne-over-gole kubva kune yakapfuura maitiro uye kuivharira kune iyo fixture plate. Wobva watenderedza nzvimbo yakavharwa sikuruu senzvimbo ichagadzirwa.
Sequential Machining nePlaten
Munguva yekugadzira machining, isu tinotanga tagadzirisa dzimwe nzvimbo kunze kwenzvimbo ichagadzirwa. Kana nzvimbo idzi dzave dzakagadzirwa, tinoisa platen panzvimbo yakagadzirwa (platen inoda kuvharwa neglue kudzivirira kupwanyika kwemashini). Isu tobva tabvisa ma screws anoshandiswa mudanho rechipiri uye toenderera mberi nekugadzira nzvimbo dzinofanirwa kugadzirwa kusvika chigadzirwa chose chapera.
Iine iyi optimized process uye fixture solution, tinogona kubata iyo yakatetepa-yakavakirwa CNC goko chikamu zviri nani uye kudzivirira matambudziko akadai se warping, kukanganisa, uye overcutting. Iyo yakasungirirwa screws inobvumira iyo fixture plate kuti isungirwe zvakasimba kune workpiece, ichipa yakavimbika chinzvimbo uye rutsigiro. Mukuwedzera, kushandiswa kweplate yekudhinda kuisa kumanikidziro panzvimbo yakagadziriswa kunobatsira kuchengetedza workpiece yakagadzikana.
In-Depth Analysis: Nzira Yekudzivisa Warping uye Deformation?
Kuwana machining akabudirira ezvimiro zvakakura uye zvakatetepa-akakomberedzwa makoko zvinoda kuongororwa kwematambudziko chaiwo mukuita machining. Ngatimbonyatsoongororai kuti matambudziko aya angakundwa sei zvinobudirira.
Pre-machining Inner Side
Muchigadziro chekutanga chekugadzira (kugadzira rutivi rwemukati), zvinyorwa isimbi yakasimba yezvinhu zvine simba guru. Naizvozvo, iyo workpiece haina kutambura kubva machining anomalies senge deformation uye warping panguva iyi. Izvi zvinogonesa kugadzikana uye kurongeka kana uchigadzira yekutanga clamp.
Shandisa Kukiya uye Kudzvanya Nzira
Yechipiri nhanho (machining uko kupisa kunyura kunowanikwa), tinoshandisa nzira yekuvhara uye yekutsikirira yekumanikidza. Izvi zvinovimbisa kuti simba rekusunga rakakwira uye rakagovaniswa zvakaenzana pane inotsigira referensi ndege. Uku kusungirira kunoita kuti chigadzirwa chigadzikane uye hachina kuputika panguva yese yekuita.
Alternative Solution: Pasina Hollow Structure
Nekudaro, isu dzimwe nguva tinosangana nemamiriro ezvinhu apo zvisingaite kugadzira screw kuburikidza neburi pasina buri chimiro. Heino imwe mhinduro.
Isu tinokwanisa kufanogadzira dzimwe mbiru panguva yekugadzira reverse side tobva tadzvanya pazviri. Munguva yeinotevera machining process, isu tine screw inopfuura nekumashure kwechigadziriso uye kukiya iyo workpiece, uyezve kuita machining echipiri ndege (kurutivi uko kupisa kunobviswa). Nenzira iyi, tinogona kupedzisa yechipiri machining nhanho mune imwechete pass pasina kuchinja ndiro pakati. Pakupedzisira, isu tinowedzera katatu clamping nhanho uye kubvisa maitiro mbiru kupedzisa maitiro.
Mukupedzisa, nekugadzirisa maitiro uye kugadzirisa mhinduro, tinogona kubudirira kugadzirisa dambudziko rehondo uye deformation yezvikamu zvakakura, zvitete zvegoko panguva yeCNC machining. Izvi hazvirevi chete machining quality uye kushanda zvakanaka asiwo kunovandudza kugadzikana uye pamusoro pemhando yechigadzirwa.
