Chifukwa Chake Makina Otsika Mtengo Angawononge Ndalama Zambiri

Woyang'anira fakitale yopangira zinthu ku Dongguan anali atangosintha makina osindikizira a hydraulic akale olemera matani 250 ndi makina atsopano ofanana ndi amenewa. Makina osindikizirawo ankawononga ndalama zosakwana theka la makina ofanana ndi a servo-hydraulic. Patatha miyezi khumi ndi isanu ndi itatu, ndalama zamagetsi za fakitaleyo pamakina opangira zinthu zinali zokwera ndi 6% kuposa chaka chapitacho - makina osindikizirawo ankagwiritsa ntchito mphamvu zambiri kuposa akale omwe anasintha. Pofika kumapeto kwa chaka chachitatu, ndalama zamagetsi zomwe zinkagwiritsidwa ntchito popangira zinthu zina zinali zitapitirira mtengo wa makina ofanana ndi a servo, asanaganizire phokoso, kufunikira kozizira, komanso nthawi yosinthira mafuta. Pomaliza pake fakitaleyo inakonzanso makina a servo ku makina omwe analipo m'malo mosintha - ndipo mphamvu zomwe ankagwiritsa ntchito zinachepa ndi theka mkati mwa mwezi woyamba wathunthu.

Kusankha pakati pa servo-hydraulic ndi hydraulic injection molding wamba si chisankho chophweka "chatsopano ndi chabwino". Ndi kuwerengera ndalama zonse za umwini kwa zaka 5 zomwe zimatengera kuchuluka kwa makina, mbiri ya kayendedwe kake, maola ogwirira ntchito, ndi mtengo wamagetsi wakomweko. Nkhaniyi ikufotokoza mwatsatanetsatane kuwerengera kumeneko - momwe kusiyana kwa mphamvu kumaonekera, momwe kusiyana kosamalira kumaonekera, komwe makina wamba amapezerabe mtengo wake, komanso momwe mungaphatikizire manambala kuti akhazikitsidwe mwanjira inayake.

Momwe Makina Osindikizira Achizolowezi Amagwiritsira Ntchito Mphamvu

Makina opangidwa ndi makina ...

Injini imayenda mofulumira kwambiri nthawi yonseyi, ngakhale pamene kufunika kwa hydraulic kuli kochepa. Panthawi yogwira ntchito - pamene gawolo likufunika kachigawo kakang'ono chabe ka peak flow kuti lisunge mphamvu ya cavity - kuyenda kochulukirapo kumadutsa kudzera mu valavu yothandiza kubwerera ku thanki, kutulutsa mphamvu ngati kutentha. Panthawi yoziziritsa - pamene palibe hydraulic flow yomwe ikufunika kupatulapo clamp tonnage yochepa - pampu ikuzungulirabe mofulumira kwambiri, ikulandirabe mphamvu zonse, ndipo valavu yodutsa ikutulutsabe flow yochulukirapo. Uku ndi kusagwira ntchito bwino kwa dongosolo lokhazikika la pampu: mota ndi pampu zimayenda pamalo amodzi ogwirira ntchito, ndipo kusiyana kulikonse pakati pa malo amenewo ndi hydraulic demand yeniyeni kumatayika ngati kutentha.

Kutentha kokha sikopanda phindu. Mafuta a hydraulic ayenera kuziziritsidwa kuti asunge kukhuthala ndikuletsa kukhuthala, zomwe zikutanthauza kuti choziziritsira mafuta china (chozizira m'madzi kapena chozizira mpweya) chikuyenda mosalekeza, zomwe zimapangitsa kuti mphamvu yowonjezera ipezeke. Kufunika koziziritsa pa makina osindikizira achikhalidwe a matani 250 mu 30 °C kumakhala kwakukulu - nthawi zambiri kumakhala pakati pa 15–25% ya mphamvu yamagetsi ya makinawo pa ntchito ya ma shift atatu.

Momwe Servo-Hydraulic System Imagwiritsira Ntchito Mphamvu

Dongosolo la servo-hydraulic limalowa m'malo mwa mota yothamanga nthawi zonse ndi mota ya servo yothamanga nthawi zonse — nthawi zambiri imakhala mota yokhazikika ya maginito synchronous (PMSM) — yoyendetsedwa ndi variable-frequency drive (VFD). Servo drive imalamulira liwiro la mota kuti igwirizane ndi kufunikira kwa hydraulic nthawi yeniyeni. Pamene kayendedwe kake kali mu gawo la high-flow (kutseka mold, injection, plasticizing), mota imakwera mofulumira kwambiri. Pamene kayendedwe kake kali mu gawo la low-flow (kugwira, kuziziritsa), mota imakwera mofulumira kwambiri yomwe imakwaniritsa kufunikira kwenikweni kwa hydraulic. Pamene kayendedwe kake kali pa mpumulo (palibe kuyenda), mota imatha kuyima kwathunthu kapena kuthamanga pa liwiro loyandikira zero.

Zotsatira zake n'zakuti makina a servo-hydraulic amangotenga mphamvu yomwe amafunikira pa gawo lililonse la kayendedwe kake. Mota siimayenda pa liwiro losasintha, pampu siidutsa kuyenda kochulukirapo, ndipo kutayika kwa kutentha kwa bypass-valve komwe kumatanthauza kusagwira bwino ntchito kwa atolankhani kumachotsedwa kwambiri.Bosch Rexroth, Yuken, ndi opanga ena a makina a hydraulic system amafalitsa zolemba zogwiritsira ntchito pogwiritsa ntchito kuyerekeza kwa mphamvu zomwe zimagwiritsidwa ntchito pogwiritsa ntchito servo poyerekeza ndi pampu yokhazikika; kuchuluka kwa nthawi zonse komwe kumafalitsidwa ndi kuchepetsa mphamvu kwa 40–80% pazigawo zomwe zili ndi magawo ofunikira ogwirira ndi kuzizira, ndi kuchepetsa kwa 20–40% pazigawo zomwe zili ndi magawo ofupikira ogwirira ndi kuzizira.

Ndalama zomwe zasungidwa sizili zofanana nthawi yonseyi. Ndalama zambiri zomwe zasungidwa zimakhala pa gawo loziziritsa (gawo lalitali kwambiri lomwe silikufunika kwambiri m'magawo ambiri), lachiwiri lalikulu kwambiri pa gawo loziritsa, ndipo laling'ono kwambiri pa gawo loziritsa (komwe kuyenda kwa madzi ambiri kumafunika ndipo makina a servo nawonso akuyenda bwino). Pa makina osindikizira a 250-ton omwe amagwiritsa ntchito mphamvu ya 200 g ABS okhala ndi nthawi ya masekondi 25, gawo loziziritsa limakhala pafupifupi 50% ya nthawi yonseyi, gawo loziritsa limakhala 15%, gawo loziritsa ndi lopaka pulasitiki limakhala 25%, ndipo gawo lotsegula/kutseka limakhala 10%. Gawo loziziritsa ndi lomwe makina a servo amasunga ndalama zambiri.

Mtengo wa Servo Premium: Mtengo wa Capital vs Mtengo Wogwirira Ntchito

Makina opangira jekeseni wa servo-hydraulic nthawi zambiri amawononga ndalama zokwana 30-60% kuposa makina wamba ofanana ndi tonnage ndi kukula kofanana kwa shot. Mtengo weniweni umadalira wopanga makina, wogulitsa makina a servo, ndi zomwe makinawo akufuna. Kwa makina osindikizira oyimira matani 250, mtengo wa servo pamsika uno ndi wokwera wa manambala asanu - wofunika, koma osati wosintha kwa manejala wa fakitale yemwe akuwunika kugula.

Ndalama zolipirira zimapezedwa kudzera mu kusunga mphamvu. Kuti muyike nambala pa kubweza, pamafunika zinthu zitatu: kusunga mphamvu pa kuzungulira, kuzungulira pa kusinthana, ndi mtengo wamagetsi.mzere wazinthu zamachitidwe a servoyapangidwira makina a servo opangidwa ndi vane-pump pa ntchito zopangira jekeseni, ndi kusunga mphamvu pamlingo wa dongosolo mumtundu wofalitsidwa.
