Itsindaimashini ikoresha servo ishyushyeikora neza binyuze mu guhuza imiterere y’ibikoresho by’ikoranabuhanga, sisitemu y’ubuhanga yo kugenzura, no kunoza imikorere. Izi zikurikira ni inzira z’ingenzi z’ikoranabuhanga n’uburyo bwo kuzishyira mu bikorwa:
1. Ingwate y'uburyo bw'ibikoresho by'ikoranabuhanga
1) Sisitemu yo gutwara moteri ya Servo
Igenzura ry'ingufu rigezweho:
Hakoreshejwe moteri za servo zikoresha direct-drive (nk'ibirango by'Abayapani bya Yaskawa na Panasonic), ubuziranenge bwo gushyiramo ibintu bugera kuri ± 0.01mm, kandi ubuziranenge bwo gusubiramo ni ± 0.005mm.
Moteri itwara neza icyuma gishyushya umuvuduko ikoresheje screw y'umupira cyangwa umurongo ngenderwaho kugira ngo igabanye "uburibwe bworoshye" bwa sisitemu isanzwe ya hydraulic (igihe cyo gusubiza cy'isitemu ya hydraulic ni nka 100ms, naho sisitemu ya servo ni <20ms).
Kugenzura umuvuduko ufunze:
Ifite sensor y'umuvuduko wo hejuru kandi ikora neza (ubunyangamugayo ± 0.1% FS), itanga igisubizo cy'umuvuduko mu gihe nyacyo kuri controller, ikora "agaciro gashyizweho → moteri → igisubizo cy'umuvuduko → guhinduranya imbaraga" mu buryo bufunze, igenzura ko ihindagurika ry'umuvuduko ari ≤ ± 1%.
2) Moduli yo kugenzura ubushyuhe
Ikoranabuhanga ryo kugenzura ubushyuhe ryigenga mu bice byinshi:
Urubuga rushyushya rukoresha icyuma gishyushya cya keramike + imiterere y'ikigega gishyushya, gifite uburyo bwo kugenzura ubushyuhe bw'ahantu (uturere 3, uturere 5, cyangwa uturere twabugenewe), kandi itandukaniro ry'ubushyuhe hagati ya buri gace ni ≤±1℃.
Ingano yo kugenzura ubushyuhe: -20℃ ~ 450℃ (bitewe n'imiterere y'icyitegererezo), igipimo cyo gushyushya gishobora guhindurwa kuva kuri 0.1~20℃/s, kandi gishyigikira gushyushya no kubungabunga ubushyuhe mu byiciro byinshi.
Gukurikirana ubushyuhe mu gihe nyacyo:
Thermocouple cyangwa thermometer ya infrared yubatswemo yo mu bwoko bwa K, ikusanya amakuru y'ubushyuhe buri masegonda 0.5, kandi igahindura ingufu zisohoka binyuze muri algorithme ya PID.
3) Kunoza imiterere y'imashini
Igishushanyo mbonera cy'urukuta gikomeye cyane:
Koresha "ubwoko bwa C" cyangwa "ubwoko bwa gantry" integral casting frame (icyuma cya HT300 cast iron), nyuma yo gusaza kugira ngo ukureho stress imbere, uburimbane ≥ 200N/μm, ugabanye frame deformation mu gihe cyo gukanda (deformation gakondo ya hydraulic press ni nka 0.1 ~ 0.3mm, servo model <0.05mm).
Ibirindiro bya kinematic bifite friction nke:
Inzira yo kuyobora ikoresha uruziga rwa THK linear guide cyangwa PMI precision screw, ifite sisitemu yo kwisiga yikora (gutanga amavuta yikora mu minota 5 ~ 30), coefficient ya friction ≤ 0.0015, kugira ngo ikure neza kandi imanure plate y'umuvuduko.
2. Kugenzura neza sisitemu z'ubuhanga mu kugenzura
1) Algorithm yo kugenzura ihuza ry’imirongo myinshi
Kugenzura uburyo igitutu gishyirwa mu mwanya wacyo n'ubushyuhe:
Binyuze muri PLC cyangwa umugenzuzi w'ingendo (nka Siemens S7-1500, Huichuan AM600), igenzura rya parametero eshatu rikorwa:
Uburyo bwo gushyira imbere umuvuduko: shyiraho umuvuduko w'icyerekezo, maze aho unyura hagahindurwa mu buryo bwikora hamwe n'uburyo ibikoresho bikandamizwa (bikoreshwa ku bikoresho biramba).
Uburyo bwo gushyira imbere kwimura: bugabanya umuvuduko wo gukanda, kandi igitutu gihita gihuzwa n'imbaraga zo gukoraho (zikoreshwa ku bikoresho bikomeye).
Uburyo buvanze: kugenzura uburyo umuvuduko uhinduka mu buryo bugabanyije (nk'uburyo bwo kwimura umuvuduko mbere na mbere, hanyuma no kubungabunga umuvuduko).
Algorithm yo kurwanya gukubita cyane:
Iyo yegereye aho umuvuduko/igitutu gishyirwa, yihindurira mu buryo bworoshye (5mm/s kugeza 0.1mm/s). Ikorana n'imikorere ya servo moteri ikora neza kugira ngo hirindwe guhungabana kw'ingufu (gukubita cyane <0.5% by'agaciro gateganyijwe).
2) Gusuzuma no gukurikirana ibipimo by'imikorere
Uburyo bwo guhuza imashini n'abantu (HMI):
Ecran ya santimetero 10 ~ 15, ishyigikira uburyo bwo gukanda porogaramu mu byiciro byinshi (nk'ubushyuhe n'umuvuduko kugeza kuri 50), kandi buri parametero ishobora gushyirwaho ukwayo (nk'umuvuduko 10 ~ 500kN, igihe cyo gufata 1 ~ 300s).
Kwerekana mu buryo nyabwo umurongo w’ubushyuhe n’umuvuduko, gushyigikira kohereza cyangwa gushyira amakuru kuri USB flash drive hakoreshejwe sisitemu ya MES, kugira ngo habeho uburyo bwo gukurikirana neza (uburyo bwo kubika amakuru: umuvuduko 0.1kN, ubushyuhe 0.1℃, igihe 1s).
3) Uburyo bwo guhanura amakosa n'uburyo bwo kwishyura
Imikorere yo kwishyurana ihinduka:
Iyo ihindagurika ry'umuvuduko rirenze ± 3%, sisitemu ihita itera imbaraga za moteri y'ubwishingizi hanyuma igasubiza agaciro kayo mu gihe kitarenze 20ms (ubwishingizi busanzwe bwo gukanda hakoreshejwe hydraulic busaba kurenza 500ms).
Ingengo y'intabaza idasanzwe:
Ushobora guhindura imipaka yo hejuru n'iyo hasi y'umuvuduko/ubushyuhe (nk'umupaka wo hejuru w'umuvuduko wa 110% FS, umupaka wo hasi w'ubushyuhe - 10℃), maze imashini izimya ikoresheje ijwi n'itangazo ry'ubushyuhe igihe umupaka urenze.
3. Guhuza uburyo bwo gutunganya no gutunganya ibumba
1) Gutunganya no gupima neza ibumba
Ibisabwa ku buziranenge bw'ubuso:
Ubukana bw'ubuso bw'ikimera Ra≤0.8μm, ubugari bwa ≤0.005mm/m, byageragejwe n'imashini ipima ibice bitatu (CMM) kugira ngo harebwe imbaraga zimwe mu gihe cyo gukanda.
Igishushanyo mbonera cya elastic buffer:
Iyi foroma ifite agakoresho gapima ubukana bwa polyurethane (ubukomere bwa Shore 50~80A) cyangwa igikoresho gipima ubushyuhe kugira ngo gihuze n'ubunini bw'ibikoresho (nk'urugero ± 0.1mm) kandi hirindwe umuvuduko ukabije w'aho hantu.
Ibi byavuzwe haruguru ni uburyo butandukanye bwo kugera ku gukanda neza ukoresheje servo hotimashini zicapa hifashishijwe hydraulicNiba ukeneye imashini ishyushye ikoresha uburyo bwo hejuru, twandikire.
