Indlela Yokufikelela Ekucinezeleni Okuchanekileyo Ngomatshini Wokucinezela Oshushu weServo

Iumatshini wokucinezela oshushu we-servoifezekisa ukucinezelwa ngokuchanekileyo ngokusebenzisana koyilo oluchanekileyo lwehardware, inkqubo yolawulo ekrelekrele, kunye nokwenza ngcono inkqubo. Ezi zilandelayo ziindlela eziphambili zobuchwepheshe kunye neendlela zokuphumeza:

1. Isiqinisekiso Esichanekileyo Senkqubo Yezixhobo Zekhompyutha

1) Inkqubo yokuqhuba imoto yeServo 

Ulawulo lwamandla oluchanekileyo kakhulu:

 Ukusebenzisa ii-servo motors eziqhutywa ngqo (ezifana neemveliso zaseJapan iYaskawa kunye nePanasonic), ukuchaneka kokubeka kufikelela kwi-±0.01mm, kwaye ukuchaneka kokuphindaphinda yi-±0.005mm.

 Injini iqhuba ngqo ipleyiti yoxinzelelo nge-screw yebhola okanye isikhokelo esithe ngqo ukunciphisa ukushiyeka "konxibelelwano oluthambileyo" kwenkqubo ye-hydraulic yendabuko (ixesha lokuphendula kwenkqubo ye-hydraulic limalunga ne-100ms, kwaye inkqubo ye-servo ingaphantsi kwama-20ms).

 Ulawulo loxinzelelo oluvaliweyo:

 Isenzi soxinzelelo esichanekileyo kakhulu esakhelwe ngaphakathi (ukuchaneka ±0.1% FS), impendulo yexesha langempela yexabiso loxinzelelo kumlawuli, yenza iluphu evaliweyo ethi "ixabiso elimiselweyo → imveliso yemoto → impendulo yoxinzelelo → uhlengahlengiso oluguquguqukayo", ukuqinisekisa ukuba ukutshintshatshintsha koxinzelelo yi-≤±1%.

2) Imodyuli yokulawula ubushushu

 Itekhnoloji yokulawula ubushushu ezimeleyo kwiindawo ezininzi:

Iqonga lokufudumeza lisebenzisa ipleyiti yokufudumeza yeseramikhi + isakhiwo sesinki sobushushu, enolawulo lobushushu bezoni (iizoni ezi-3, iizoni ezi-5, okanye iizoni ezenziwe ngokwezifiso), kwaye umahluko wobushushu phakathi kwezoni nganye yi-≤±1℃.

Uluhlu lolawulo lobushushu: -20℃ ~ 450℃ (kuxhomekeke kulungiselelo lwemodeli), izinga lokufudumeza linokulungiswa ukusuka kwi-0.1~20℃/s, kwaye lixhasa ukufudumeza okuhambayo kunye neenkqubo zokugcinwa kobushushu obungaguqukiyo ezinamanqanaba amaninzi.

 Ukubeka esweni ubushushu ngexesha langempela:

 I-thermocouple yohlobo lwe-K okanye i-thermometer ye-infrared eyakhelwe ngaphakathi, iqokelela idatha yobushushu rhoqo emva kwemizuzwana eyi-0.5, kwaye ilungisa amandla ngokuguquguqukayo nge-algorithm ye-PID.

3) Ukulungiswa kwesakhiwo soomatshini

Uyilo lwesakhelo sokuqina okuphezulu:

Sebenzisa isakhelo sokudibanisa esipheleleyo se-“C-type” okanye “gantry-type” (intsimbi ye-HT300 cast material), emva kokwaluphala ukuze ususe uxinzelelo lwangaphakathi, ubulukhuni ≥ 200N/μm, unciphise ukuguquguquka kwesakhelo ngexesha lokucinezela (ukuguquguquka kwe-hydraulic press yendabuko malunga ne-0.1 ~ 0.3mm, imodeli ye-servo <0.05mm).

Isibini se-kinematic esinoxinzelelo oluphantsi:

Ireyile yesikhokelo isebenzisa ireyile yesikhokelo ye-THK okanye i-PMI precision screw, enenkqubo yokuthambisa ezenzekelayo (unikezelo lweoyile oluzenzekelayo ngamaxesha athile emizuzu emi-5 ukuya kwengama-30), i-friction coefficient ≤ 0.0015, ukuqinisekisa ukuphakamisa nokuhla kwepleyiti yoxinzelelo ngokutyibilikayo.

2. Ulawulo Oluchanekileyo lweeNkqubo zoLawulo oluBukrelekrele

1) I-algorithm yolawulo lonxibelelwano lwe-Multi-axis

 Ulawulo lokudibanisa ubushushu boxinzelelo-ukufuduka:

 Ngokusebenzisa i-PLC okanye isilawuli sokuhamba (esifana ne-Siemens S7-1500, i-Huichuan AM600), ulawulo oluhambelanayo lweeparameter ezintathu luyafezekiswa:

 Imo yokubeka phambili uxinzelelo: seta uxinzelelo olujoliswe kulo, kwaye ukufuduka kulungiswa ngokuzenzekelayo ngoxinzelelo lwezinto (olusebenza kwizinto ezithambileyo).

 Imo yokubeka phambili ukufuduka: inciphisa ukubetheka okucinezelweyo, kwaye uxinzelelo luhambelana ngokuzenzekelayo namandla oqhagamshelwano (asebenza kwizinto eziqinileyo).

 Imo exutyiweyo: ulawulo lokutshintsha uxinzelelo oluhlukaniswe ngokwezigaba (njengokufuduka ngokukhawuleza kuqala, uze emva koko ugcinwe uxinzelelo).

 I-algorithm yokulwa nokudubula okugqithisileyo:

 Xa isondela kwindawo ekujoliswe kuyo uxinzelelo/ukususwa, itshintshela ngokuzenzekelayo kwimowudi yesantya esiphantsi (5mm/s ukuya kwi-0.1mm/s). Isebenzisana nomsebenzi wokuqhobosha we-servo motor ukuze kuthintelwe ukuqhawuka kwe-inertial (ukudubula ngaphezulu kwe-0.5% yexabiso elibekiweyo).

2) Ukubona kunye nokulandeleka kweeparamitha zenkqubo

 Ujongano lomatshini womntu (HMI):

Isikrini sokuchukumisa esiyi-10~15-intshi, sixhasa ukuhlelwa kwenkqubo yokucinezela ngamanqanaba amaninzi (njengokudibanisa ukuya kuthi ga kwi-50 yexesha loxinzelelo-lobushushu), kwaye iparameter nganye inokuseta ngokuzimeleyo (njengoxinzelelo lwe-10~500kN, ixesha lokubamba li-1~300s).

 Umboniso wexesha langempela we-pressure-displacement-temperature curve, inkxaso yokuthumela idatha kwi-USB flash drive okanye i-docking ngenkqubo ye-MES, ukufezekisa ukulandeleka kwenkqubo (ukuchaneka kokugcinwa kwedatha: uxinzelelo lwe-0.1kN, ubushushu be-0.1℃, ixesha le-1s).

3) Indlela yokuqikelela iimpazamo kunye nendlela yokuhlawula

Umsebenzi wembuyekezo enamandla:

Ukuba ukuguquguquka koxinzelelo kudlula i-±3%, inkqubo ivuselela ngokuzenzekelayo i-torque ye-compension motor kwaye ibuyisele ixabiso elibekiweyo ngaphakathi kwe-20ms (i-hydraulic press regular compensation ifuna ngaphezulu kwe-500ms).

Umlinganiselo we-alamu ongaqhelekanga:

Ungayilungisa imida ephezulu nesezantsi yoxinzelelo/yobushushu (njengomda ophezulu woxinzelelo lwe-110% FS, umda ophantsi wobushushu - 10℃), kwaye umatshini uya kuzicima ngokuzenzekelayo kwaye ukhale kwaye ukhanyise i-alamu xa umda udlulile.

3. Ukulungelelaniswa kokulungiswa kwesikhunta kunye nenkqubo

1) Ukucubungula ngokuchanekileyo kunye nokuvavanya isikhunta

Iimfuno zokuchaneka komphezulu:

Uburhabaxa bomphezulu wesikhunta iRa≤0.8μm, ubuthe tyaba ≤0.005mm/m, buvavanywe ngomatshini wokulinganisa onamakhonkco amathathu (CMM) ukuqinisekisa amandla afanayo ngexesha lokucinezela.

 Uyilo lwe-elastic buffer:

Isikhunta sixhotyiswe nge-polyurethane buffer pad (hardness Shore 50~80A) okanye isixhobo esintantayo esinomoya ukuze silungise ukunyamezelana kobukhulu bezinto (ezifana ne-±0.1mm) kwaye siphephe uxinzelelo olugqithisileyo lwendawo.
