Themakina osindikizira otentha a servoimakwaniritsa kukanikiza kolondola kudzera mu mgwirizano wa kapangidwe ka hardware molondola, makina owongolera anzeru, komanso kukonza njira. Izi ndi njira zazikulu zaukadaulo ndi njira zogwiritsira ntchito:
1. Chitsimikizo Cholondola cha Dongosolo la Zida
1) Dongosolo loyendetsa mota ya Servo
Kulamulira mphamvu molondola kwambiri:
Pogwiritsa ntchito ma servo motors oyendetsedwa mwachindunji (monga mitundu ya Japan ya Yaskawa ndi Panasonic), kulondola kwa malo kumafika ±0.01mm, ndipo kulondola kobwerezabwereza ndi ±0.005mm.
Mota imayendetsa mwachindunji mbale yokakamiza kudzera mu screw ya mpira kapena chitsogozo cholunjika kuti ichepetse kuchedwa kwa "kulumikizana kofewa" kwa dongosolo lachikhalidwe la hydraulic (nthawi yoyankhira ya dongosolo la hydraulic ndi pafupifupi 100ms, ndipo dongosolo la servo ndi <20ms).
Kulamulira kuthamanga kotsekedwa:
Chojambulira cha kuthamanga kwa mpweya chomangidwa mkati mwake (cholondola ± 0.1% FS), yankho la kuthamanga kwa mpweya nthawi yeniyeni kwa wolamulira, ndikupanga "mtengo wokhazikika → kutulutsa kwa injini → yankho la kuthamanga kwa mpweya → kusintha kwa mphamvu" kuzungulira kotsekedwa, kuonetsetsa kuti kusinthasintha kwa kuthamanga kwa mpweya ndi ≤±1%.
2) Gawo lowongolera kutentha
Ukadaulo wodziyimira pawokha wowongolera kutentha m'malo ambiri:
Pulatifomu yotenthetsera imagwiritsa ntchito mbale yotenthetsera ya ceramic + sinki yotenthetsera, yokhala ndi kuwongolera kutentha kwa dera (madera atatu, madera asanu, kapena madera okonzedwa), ndipo kusiyana kwa kutentha pakati pa dera lililonse ndi ≤±1℃.
Kulamulira kutentha: -20℃ ~ 450℃ (kutengera kapangidwe ka chitsanzo), kutentha kumatha kusinthidwa kuyambira 0.1~20℃/s, ndipo kumathandizira kutentha kwa ramp ndi kukonza kutentha kosalekeza mapulogalamu ambiri.
Kuwunika kutentha kwa nthawi yeniyeni:
Thermocouple ya mtundu wa K kapena thermometer ya infrared, imasonkhanitsa deta ya kutentha masekondi 0.5 aliwonse, ndikusintha mphamvu yotulutsa kudzera mu njira ya PID.
3) Kukonza kapangidwe ka makina
Kapangidwe ka chimango cholimba kwambiri:
Gwiritsani ntchito chimango cha "C-type" kapena "gantry-type" chopangira zinthu (chitsulo chopangidwa ndi HT300), mutachigwiritsa ntchito kuti muchepetse kupsinjika kwamkati, kulimba ≥ 200N/μm, chepetsani kusintha kwa chimango mukakanikiza (kusintha kwa makina osindikizira a hydraulic ndi pafupifupi 0.1 ~ 0.3mm, mtundu wa servo <0.05mm).
Chipinda cha kinematic chocheperako:
Sitima yowongolera imagwiritsa ntchito THK linear guide rail kapena PMI precision screw, yokhala ndi automatic lubrication system (mafuta odzipangira okha pakapita mphindi 5 mpaka 30), friction coefficient ≤ 0.0015, kuti zitsimikizire kuti pressure plate ikukwezedwa bwino komanso kutsika.
2. Kuwongolera Mwanzeru kwa Machitidwe Olamulira Anzeru
1) Njira yowongolera kulumikizana kwa ma axis ambiri
Kulamulira kolumikizira kutentha ndi kuthamanga:
Kudzera mu PLC kapena chowongolera mayendedwe (monga Siemens S7-1500, Huichuan AM600), kuwongolera kogwirizana kwa magawo atatu kumachitika:
Kukakamiza koyambirira: khazikitsani kukakamiza komwe mukufuna, ndipo kusamukako kumasinthidwa zokha ndi kukanikiza kwa zinthu (kogwiritsidwa ntchito pa zinthu zotanuka).
Njira yoyendetsera zinthu zofunika kwambiri: imachepetsa kukanikiza, ndipo kupanikizika kumafanana ndi mphamvu yolumikizirana (yogwiritsidwa ntchito pa zinthu zolimba).
Njira yosakanikirana: kuwongolera kusinthasintha kwa kuthamanga ndi kusamuka kwa magetsi (monga kusamuka mwachangu poyamba, kenako kukonza kuthamanga).
Njira yotsutsana ndi kupitirira muyeso:
Ikayandikira kupanikizika/kusamuka komwe ikufuna, imasintha yokha kukhala mode yothamanga pang'ono (5mm/s mpaka 0.1mm/s). Imagwirizana ndi ntchito yoyendetsa mabuleki ya mota ya servo kuti ipewe kugwedezeka kwa inertial (kupitirira muyeso <0.5% ya mtengo wokhazikitsidwa).
2) Kuwona ndi kutsata magawo a ndondomeko
Mawonekedwe a makina a anthu (HMI):
Chophimba chogwira cha mainchesi 10 ~ 15, chimathandizira kusintha kwa mapulogalamu okanikiza magawo ambiri (monga kuphatikiza kwa nthawi yopanikizika ndi kutentha mpaka 50), ndipo gawo lililonse likhoza kukhazikitsidwa palokha (monga kuthamanga 10 ~ 500kN, kugwira nthawi 1 ~ 300s).
Kuwonetsa nthawi yeniyeni kwa curve ya pressure-displacement-temperature, kuthandizira kutumiza deta ya USB flash drive kapena docking ndi MES system, kuti mupeze njira yotsatirira (kulondola kosungira deta: pressure 0.1kN, kutentha 0.1℃, nthawi 1s).
3) Kuneneratu zolakwika ndi njira yolipirira
Ntchito yolipirira mphamvu:
Ngati kusinthasintha kwa kuthamanga kwa mpweya kukupitirira ± 3%, makinawo amayambitsa mphamvu ya injini yolipirira ndikubwezeretsa mtengo womwe wayikidwa mkati mwa 20ms (malipiro achikhalidwe a hydraulic press amafuna kupitirira 500ms).
Malire a alamu osadziwika bwino:
Mukhoza kusintha malire apamwamba ndi otsika a kuthamanga/kutentha (monga malire apamwamba a kuthamanga 110% FS, malire otsika a kutentha - 10℃), ndipo makinawo azizima okha ndikumveka ndikuyatsa alamu akapitirira malirewo.
3. Kukonza bwino nkhungu ndi njira zake
1) Kukonza ndi kuyesa bwino nkhungu
Zofunikira pakulondola pamwamba:
Kukhwima kwa pamwamba pa nkhungu Ra≤0.8μm, kusalala ≤0.005mm/m, kunayesedwa ndi makina oyezera atatu (CMM) kuti atsimikizire mphamvu yofanana pakukanikiza.
Kapangidwe ka buffer kotanuka:
Chikombolecho chili ndi polyurethane buffer pad (hardness Shore 50~80A) kapena chipangizo choyandama chomwe chimayendetsedwa ndi mpweya kuti chigwirizane ndi kupirira kwa makulidwe a zinthuzo (monga ± 0.1mm) ndikupewa kupanikizika kwambiri komweko.
Izi ndi njira zingapo zokwaniritsira kukanikiza kolondola ndi servo hotmakina osindikizira a hydraulicNgati mukufuna makina osindikizira otentha olondola kwambiri, chonde titumizireni uthenga.
