Maitiro Ekuwana Kudzvanya Kwakarurama Nemuchina weServo Hot Pressing

Iyomuchina wekudzvanya weservo unopisaInoita kuti kudzvanywa kwacho kuve kwakanyatsojeka kuburikidza nekubatana kwekugadzirwa kwehardware chaiyo, system yekudzora yakangwara, uye kugadzirisa maitiro. Inotevera ndiyo nzira huru dzetekinoroji uye nzira dzekushandisa:

1. Vimbiso Yechokwadi yeSisitimu yeHardware

1) Sisitimu yekufambisa mota yeServo 

Kudzora simba nemazvo:

 Uchishandisa mamota eservo anotyaira zvakananga (akadai semabhurugwa eJapan Yaskawa nePanasonic), kururama kwenzvimbo kunosvika ±0.01mm, uye kururama kwekudzokororwa kuri ±0.005mm.

 Mota iyi inofambisa zvakananga ndiro yekumanikidza kuburikidza nesikuruu yebhora kana gwara rakatsetseka kuderedza "kubatana kwakapfava" kwehurongwa hwechinyakare hwehydraulic (nguva yekupindura yehurongwa hwehydraulic ingangoita 100ms, uye system yeservo i <20ms).

 Kudzora kudzvanywa kwedzvinyiriro:

 Sensor yekumanikidza yakavakirwa mukati ine kunyatsorongeka (kururama ±0.1% FS), mhinduro chaiyo yehuwandu hwekumanikidza kune controller, ichigadzira "set value → motor output → pressure feedback → dynamic adjustment" loop yakavharwa, ichivimbisa kuti pressure fluctuation iri ≤±1%.

2) Module yekudzora tembiricha

 Tekinoroji yekudzora tembiricha yakazvimirira ine nzvimbo dzakawanda:

Puratifomu yekudziya inoshandisa ndiro yekudziya yeceramic + sink yekupisa, ine tembiricha yekudzora nzvimbo (nzvimbo nhatu, nzvimbo shanu, kana nzvimbo dzakagadzirwa), uye musiyano wetembiricha pakati penzvimbo imwe neimwe i ≤±1℃.

Kudzora tembiricha: -20℃ ~ 450℃ (zvichienderana nemagadzirirwo emodhi), mwero wekupisa unogadziriswa kubva pa 0.1~20℃/s, uye unotsigira kudziyisa kwe ramp uye kuchengetedza tembiricha nguva dzose.

 Kutarisa tembiricha munguva chaiyo:

 Thermocouple yemhando yeK kana kuti infrared thermometer yakavakirwa mukati, inounganidza data retembiricha masekondi 0.5 ega ega, uye inogadzirisa simba rinobuda kuburikidza nePID algorithm.

3) Kugadzirisa chimiro chemuchina

Dhizaini yefuremu yakasimba kwazvo:

Shandisa furemu ye "C-type" kana "gantry-type" integral casting frame (yesimbi yakagadzirwa neHT300), mushure mekukwegura kubvisa kushushikana kwemukati, kuomarara ≥ 200N/μm, kuderedza kushanduka kwefuremu panguva yekudzvanya (kushanduka kwedhiraivha yedhiraivha yechinyakare kunenge 0.1~0.3mm, servo model <0.05mm).

Kinematic pair ine friction yakaderera:

Njanji yekufambisa inoshandisa THK linear guide rail kana PMI precision screw, ine otomatiki lubrication system (otomatiki oil supply panguva dze5 ~ 30 minutes), friction coefficient ≤ 0.0015, kuti ive nechokwadi chekusimudza nekudzika kwepressure plate zvakanaka.

2. Kudzora Kwakarurama kweMasisitimu Ekudzora Akangwara

1) Algorithm yekudzora kubatana kwematanho akawanda

 Kudzora kubatana kwekupisa-kumanikidzwa-kwekutamiswa-kwekupisa:

 Kuburikidza nePLC kana motion controller (yakadai seSiemens S7-1500, Huichuan AM600), three-parameter synchronous control inowanikwa:

 Maitiro ekuisa kudzvanywa kwekutanga: isa kudzvanywa kwaunoda, uye kudzvanywa kwacho kunogadziriswa otomatiki nekudzvanywa kwezvinhu (zvinoshanda kune zvinhu zvinonamira).

 Maitiro ekutanga eDisplacement: anoderedza kudzvanywa kwesimbi, uye kumanikidzwa kunoenderana otomatiki nesimba rekubata (rinoshanda kune zvinhu zvakaoma).

 Modhi yakasanganiswa: kudzora kuchinjika kwesimba nekuchinjana (segmented switching pressure-displacement control) (sekunge kutanga nekukurumidza kuchinjika, wozogadzirisa kumanikidzwa).

 Algorithm yekudzivirira kupfura zvakanyanya:

 Kana yasvika padanho rekumanikidzwa/kubviswa, inochinja yega kuenda kumodhi yekumhanya kwakaderera (5mm/s kusvika 0.1mm/s). Inoshanda pamwe chete nebasa remabhureki rinochinja-chinja remota yeservo kudzivirira kuvhunduka kweinertial (overshoot <0.5% yehuwandu hwakatarwa).

2) Kuona uye kutevedza ma process parameters

 Hunhu hwemuchina wevanhu (HMI):

Sikirini yekubata ine 10~15-inch, inotsigira kugadzirisa mapurogiramu ekudzvanya-dzvanya akawanda (sekusvika ku50 pressure-tembiricha-time combinations), uye parameter yega yega inogona kuiswa yega (sekudzvanya 10~500kN, ichibata nguva 1~300s).

 Kuratidzwa kwecurve yekupisa-kumanikidzwa-kwekudzingwa-kwemhepo panguva chaiyo, rutsigiro rwekutumira data reUSB flash drive kana kudhoka neMES system, kuti uwane kurongeka kwemaitiro (kurongeka kwekuchengetedza data: kumanikidzwa 0.1kN, tembiricha 0.1℃, nguva 1s).

3) Kufanotaura zvikanganiso uye nzira yekubhadhara

Basa rekugadzirisa rinochinja-chinja:

Kana kuchinja kwekumanikidzwa kuchidarika ±3%, sisitimu yacho inokonzeresa otomatiki torque yemota yekutsiva uye inodzoreredza kukosha kwakaiswa mukati me20ms (muripo wedhiraivha yedhiraivha yechinyakare unoda kupfuura 500ms).

Chiyero chearamu chisina kujairika:

Unogona kugadzirisa miganhu yepamusoro neyakaderera yekumanikidzwa/tembiricha (senge muganhu wepamusoro wekumanikidzwa 110% FS, muganhu wepasi wetembiricha - 10℃), uye muchina unodzima otomatiki woridza uye wobatidza alarm kana muganho wapfuura.

3. Kugadziriswa kwakarongeka kwechimiro uye maitiro

1) Kugadzirisa nekunyatsoongorora mold

Zvinodiwa pakururamisa pamusoro:

Kuoma kwechinhu chacho pamusoro pechiumbwa Ra≤0.8μm, kupfava ≤0.005mm/m, kwakaedzwa nemuchina wekuyera une makoni matatu (CMM) kuti uve nechokwadi chekuti simba rakaenzana panguva yekudzvanya.

 Dhizaini ye elastic buffer:

Chiumbwa ichi chine polyurethane buffer pad (hardness Shore 50~80A) kana mudziyo unoyangarara nemhepo kuti utsigire ukobvu hwezvinhu (senge ±0.1mm) uye kudzivirira kumanikidzwa kwakanyanya munzvimbo yacho.

Izvi zviri pamusoro apa inzira dzinoverengeka dzekuti unyatsodzvanya uchishandisa servo hotmichina yekudhinda ye hydraulicKana muchida muchina wekudzvanya zvinopisa une manyuko epamusoro, ndapota taurai nesu.
