Servo Hydraulic vs Hydraulic Injection Molding isanzwe: Igereranya ry'ikiguzi cy'imyaka 5

Impamvu imashini ihendutse ishobora guhenda cyane

Umuyobozi w’uruganda rukora ibikoresho byo gushushanya i Dongguan yari aherutse gusimbuza imashini isanzwe ya hydraulic hydraulic pressure ishaje ya toni 250 n’imashini nshya ifite imiterere nk’iyo. Iyi mashini isimbura yaguraga amafaranga ari munsi ya kimwe cya kabiri cy’imashini isanzwe ya servo-hydraulic. Amezi cumi n’umunani nyuma yaho, fagitire y’amashanyarazi y’uruganda ku gisenge cy’imashini yari hejuru ya 6% ugereranyije n’umwaka wabanjirije uwo - imashini isanzwe yakoreshaga ingufu nyinshi ugereranyije n’iya kera yari yasimbuye. Mu mpera z’umwaka wa gatatu, ikiguzi cy’amashanyarazi cy’imashini isanzwe cyari cyarenze igiciro cy’imashini isanzwe ya servo, mbere yo gushyira mu byiciro urusaku, gukonjesha, n’igihe cyo guhindura amavuta. Uru ruganda rwaje kongera gushyira sisitemu ya servo ku mashini isanzwe aho kuyisimbuza - kandi ingufu zakoreshejwe zagabanutseho kimwe cya kabiri mu kwezi kwa mbere kuzuye.

Guhitamo hagati yo gukoresha servo-hydraulic na hydraulic injection molding isanzwe si icyemezo cyoroshye cyo "gushya ni byiza kurushaho". Ni ikiguzi cy'imyaka 5 cyo kubara gishingiye ku ngano y'imashini, imiterere y'uruziga, amasaha yo gukora, n'ikiguzi cy'amashanyarazi yo mu gace utuyemo. Iyi ngingo isobanura neza icyo gipimo - uko icyuho cy'ingufu gisa, uko icyuho cyo kubungabunga gisa, aho imashini isanzwe ibona igiciro cyayo, n'uburyo bwo gushyira hamwe imibare kugira ngo ishyirweho runaka.

Uburyo Imashini Isanzwe Ikoresha Ingufu za Hydraulic

Imashini isanzwe ikoresha pompe ihoraho ikoresha hydraulic itera moteri y'amashanyarazi ku muvuduko uhoraho, akenshi ihuzwa neza n'umuyoboro w'amashanyarazi nta frequencing ihindagurika. Moteri itwara pompe ihoraho ikoresha hydraulic - akenshi pompe ifite vane cyangwa pompe ya piston - itanga amazi ahoraho akoreshwa mu buryo bujyanye n'umuvuduko ujyanye n'umutwaro. Valve zo kugenzura icyerekezo, valves zijyanye n'icyerekezo, na valves za servo zihindura imikorere n'umuvuduko kugira ngo bihuze n'igihe imashini ifunga, itera, ifata, ikora plastike, kandi ifunguye mu gihe cy'uruziga.

Moteri ikora ku muvuduko wose mu gihe cyose cy’uruziga, ndetse n’igihe igikenewe cya hydraulic kiri hasi. Mu gihe cyo gufata - iyo igice gikeneye igice gito cy’umuvuduko wo hejuru kugira ngo gikomeze umuvuduko wo mu mwobo - umuvuduko urenze unyura muri valve yo gufasha ugaruka mu kigega, igakuraho ingufu nk'ubushyuhe. Mu gihe cyo gukonjesha - iyo nta muvuduko wa hydraulic ukenewe na gato uretse toni nke ya clamp - pompe iracyazenguruka ku muvuduko wose, iracyakoresha imbaraga zose, kandi valve ya bypass iracyasohora umuvuduko urenze. Uku ni ukudakora neza kwa sisitemu ya pompe idahinduka: moteri na pompe bikorera ahantu hamwe, kandi ukudahuza kuri iyo ngingo n'igikenewe cya hydraulic biratakara nk'ubushyuhe.

Ubushyuhe ubwabwo ntabwo burimo ubusa. Amavuta ya hydraulic agomba gukonjeshwa kugira ngo agumane ubushyuhe no gukumira ogisijeni, bivuze ko icyuma gikonjesha amavuta gitandukanye (gikonjeshwa n'amazi cyangwa gikonjeshwa n'umwuka) gikomeza gukora, bigatuma imbaraga ziyongera. Ubushyuhe bukenewe ku gikoresho gisanzwe cya toni 250 mu bushyuhe bwa 30 °C ni bwinshi - akenshi kiri hagati ya 15–25% by'amashanyarazi y'imashini mu gihe cy'imashini ikora inshuro eshatu.

Uburyo Sisitemu ya Servo-Hydraulic Ikoresha Ingufu

Sisitemu ya servo-hydraulic isimbuza moteri yihuta idahinduka na moteri ya servo yihuta idahinduka — ubusanzwe moteri ihoraho ihuza magnet (PMSM) — itwarwa na drive yihuta idahinduka (VFD). Servo igenzura umuvuduko wa moteri kugira ngo ihuze n'ibikenewe na hydraulic mu gihe nyacyo. Iyo cycle iri mu cyiciro cy'umuvuduko mwinshi (gufunga mold, gutera, gushyiramo plasticization), moteri irazamuka kugeza ku muvuduko mwinshi. Iyo cycle iri mu cyiciro cy'umuvuduko muto (gufata, gukonjesha), moteri iramanuka kugeza ku muvuduko muto uhura n'ibikenewe na hydraulic. Iyo cycle iri kuruhuka (nta kugenda), moteri ishobora guhagarara burundu cyangwa ikagenda ku muvuduko hafi ya zeru.

Ingaruka ni uko imashini ya servo-hydraulic ikoresha imbaraga ikenera gusa kuri buri cyiciro cy'uruziga. Moteri ntikora ku muvuduko uhoraho, pompe ntirenga umuvuduko urenze urugero, kandi uburyo bwo gusohora ubushyuhe bwa bypass-valve bugaragaza ko icyuma gikoreshwa nabi mu gusohora amashanyarazi bukurwaho cyane.Bosch Rexroth, Yuken, n'abandi bakora sisitemu ya hydraulic basohora inyandiko zikoreshwa hamwe n'igereranya ry'ikoreshwa ry'ingufu za servo na pompe zidahinduka; urwego rusanzwe mu makuru yasohotse ni ukugabanya ingufu hagati ya 40–80% ku bice bifite icyiciro gikomeye cyo gufata no gukonjesha, na kugabanya hagati ya 20–40% ku bice bifite icyiciro gito cyo gufata no gukonjesha.

Izigamirwa ntizingana mu gihe cyose cy’izunguruka. Izigamirwa rinini ni mu gihe cyo gukonjesha (igihe kirekire cyane kidakenewe cyane mu ngendo nyinshi), icya kabiri kinini mu gihe cyo gukonjesha, n’icya gito mu gihe cyo gukonjesha (aho amazi aturuka ku rugero rwo hejuru akenewe kandi sisitemu ya servo nayo ikora ku rugero rwo hejuru). Ku gikoresho gisanzwe cya toni 250 gikoresha icyuma cya ABS cya 200 g gifite uruziga rw’amasegonda 25, igihe cyo gukonjesha ni hafi 50% by’uruziga, igihe cyo gukonjesha ni 15%, igihe cyo gukonjesha ni 25%, naho igihe cyo gufungura/gufunga ni 10%. Igihe cyo gukonjesha niho imashini ya servo izigama cyane.

Ikiguzi cya Servo: Ikiguzi cy'Imari n'Ikiguzi cy'Ibikorwa

Imashini ikoresha servo-hydraulic injection molding igura amafaranga angana na 30-60% ugereranyije n'imashini isanzwe ifite toni imwe n'ingano imwe. Ikiguzi nyacyo giterwa n'uwakoze imashini, uwatanze sisitemu ya servo, n'imiterere y'imashini. Ku mashini ikoresha toni 250, servo premium ku isoko ry'ubu ni inyongera y'amanota atanu - ifite icyo ivuze, ariko ntabwo ari impinduka ku muyobozi w'uruganda usuzuma ibyaguzwe.

Amafaranga y'inyongera yishyurwa binyuze mu kuzigama ingufu. Kugira ngo ushyire inomero ku mushahara, hakenewe ibintu bitatu: kuzigama ingufu kuri buri ruziga, uruziga kuri buri ruziga, n'ikiguzi cy'amashanyarazi.umurongo w'ibicuruzwa bya sisitemu ya servoyagenewe sisitemu za servo zishingiye kuri vane-pompe ku ikoreshwa rya injection molding, hamwe n'uburyo bwo kuzigama ingufu mu rwego rwa sisitemu mu cyiciro cyasohotse. Ku mashini ya toni 250 ku ruziga rw'amasegonda 25 ikora amasaha 6.000 ku mwaka (hafi inshuro ebyiri zikurikirana), kuzigama amashanyarazi buri mwaka biba biri ku rugero rufatika - ruhagije kugira ngo rwishyure servo premium mu mezi 18-36 ya mbere y'akazi, bitewe n'ikiguzi cy'amashanyarazi cyo mu gace.

Amakuru ya PlastikinaIkoranabuhanga rya Plastikibasohoye amakuru y’ubushakashatsi bw’imyaka myinshi agaragaza ko imashini zikoresha servo-hydraulic ubu ziganje mu kugurisha ibyuma bishya biri hagati ya toni 50 na 800 muri Amerika ya Ruguru, i Burayi, na Aziya y’Iburasirazuba, aho imashini zisanzwe zikoresha toni nyinshi kandi zidasanzwe. Impinduka ku isoko ubwaryo ni ikimenyetso cy’imibare y’ubwishyu: iyo servo premium idasubizwa mu myaka 3, isoko ntiryari guhinduka.

Kubungabunga: Aho sisitemu ebyiri zitandukanye

Uburyo bwo kubungabunga sisitemu ya servo-hydraulic butandukanye n'uburyo imashini ikoresha mu gucapa bisanzwe mu bice bitatu.

Ubwa mbere, moteri ya servo ubwayo ifite uburyo bwo kuyibungabunga buke ugereranyije na moteri ya induction ifite imbaraga zingana - nta brush, nta slip rings, kandi rotor ya magnet ihoraho ntisaba ingufu zidasanzwe. VFD ifite uburyo bwayo bwo kuyibungabunga (abafana bakonjesha, capacitors za electrolytic zifite ubuzima bwo kuyibungabunga buzamara imyaka 8-12), ariko ibice bikora bya moteri ubwayo byagenewe ubuzima bwo kuyibungabunga budasubirwaho.

Icya kabiri, pompe ya hydraulic muri sisitemu ya servo ikora ku muvuduko uhinduka kandi akenshi ikora ku mpuzandengo iri hasi ya RPM ugereranyije na pompe idahinduka ku gikoresho gisanzwe. RPM iri hasi y’impuzandengo bivuze ko ubwikorezi budasaza neza, ubwikorezi buke bw’ubushyuhe, n’igihe kirekire cyo gufunga. Amakuru atangazwa na servoIkoranabuhanga ryo Gukora Ibumbakandi abatanga pompe zitandukanye za hydraulic bagaragaza buri gihe ko pompe za vane muri serivisi y’umuvuduko uhindagurika zifite igihe kirekire cyo gukora kurusha pompe imwe ya vane muri serivisi y’umuvuduko uhoraho ku gikoresho gisa n’icyo.

Icya gatatu, icyuma gikonjesha amavuta kiri kuri servo-hydraulic press ntigikora neza kuko ubushyuhe bwa bypass-valve bugabanuka. Umufana ukonjesha cyangwa pompe y'amazi akonjesha bizenguruka kandi bigahita bizimya bitewe n'ubushyuhe nyabwo bw'amavuta aho gukora buri gihe. Igihe gito cyo gukoresha icyuma gikonjesha bivuze ko icyuma gikonjesha gito kandi amashanyarazi aturuka kuri sisitemu yo gukonjesha akaba make.

Ku rundi ruhande, imashini isanzwe ikoresha moteri n'ipompo, ikoresha uburyo bwo gusimbuza amavuta kenshi, kandi ikoresha ubushyuhe bwinshi ku mavuta, ibyo bigatuma amavuta yihuta kandi bigagabanya igihe cyo guhindura amavuta. Ku imashini isanzwe ikoresha uburyo butatu, igihe cyo guhindura amavuta gikunze kuba amasaha 4.000; ku imashini ikoresha uburyo bwa servo-hydraulic ku buryo bumwe, igihe kingana n'amasaha 6.000-8.000. Igiciro cy'amavuta mu gihe cy'imyaka 5 gifite akamaro - imashini ikoresha toni 250 itwara litiro 400-600 z'amavuta ya hydraulic, kandi ikiguzi cy'amavuta hamwe n'icyo kuyajugunya kuri buri mpinduka ni ibintu bine mu masoko menshi.

Urusaku n'ahantu ho gukorera

Imashini isanzwe ikoresha moteri na pompe ku muvuduko wose uhoraho, igatanga ikimenyetso gihamye cy’ijwi mu rugero rwa 78–85 dB (A) kuri sitasiyo y’umukoresha. Imashini ikoresha servo-hydraulic igabanya umuvuduko wa moteri na pompe mu gihe cyo gufata no gukonjesha, bigagabanya cyane urusaku ruturuka kuri sisitemu ya hydraulic. Urusaku rw’imashini yose rugabanuka rugera kuri 65–72 dB (A), iri ni itandukaniro riri hagati y’urwego rw’urusaku rusaba uburinzi bwo kumva kugira ngo umuntu agaragare mu gihe cyose n’urusaku ruri ku rwego rw’ibanze.

Kugabanya urusaku si ukugabanya ikiguzi mu buryo butaziguye, ariko ni inyungu nyayo ku masoko afite amategeko akaze agenga urusaku mu kazi (EU OSH Directive 2003/10/EC, US OSHA 29 CFR 1910.95, China GBZ 2.2) aho itangazamakuru risanzwe risaba uburinzi bwo kumva ku bakoresha. Ikiguzi cyo kurinda kumva, gupima amajwi, n'ibikorwaremezo byo kugenzura urusaku ku ruganda ntabwo akenshi bibarwa mu ibarwa ry'amafaranga akoreshwa mu ngufu gusa - ariko ni ikiguzi nyacyo mu myaka 5.

Uburyo bwo gukora neza no gusubiramo ibintu

Sisitemu ya servo-hydraulic ifite akarusho gakomeye katagaragara buri gihe mu ibarwa ry’ingufu ariko kagaragara mu gipimo cy’ibisigazwa. Igenzura ry’umuvuduko rifunze rikoresheje sensor y’umuvuduko na pompe y’umuvuduko uhindagurika rifata umuvuduko mu mwobo ukomeye kurusha sisitemu ya pompe ihoraho ifite valves zingana. Ku bice bito bihangana - optique, medical, packing - kuzamura igipimo cy’ibisigazwa byonyine bishobora kwishyura servo premium mu gihe cy’imyaka 5, hatitawe ku kuzigama ingufu.

Ishyirahamwe ry'Abahanga mu by'Imashini zikora Plastikiisohora inyandiko za tekiniki ku bijyanye no gutunganya neza inshinge za servo-hydraulic, harimo ihindagurika ry'uburemere bw'ishoti kuva ku ishoti kugeza ku ishoti ndetse n'amakuru ajyanye no gusubiramo ingano. Inyungu y'ubuziranenge yasohotse ni nto ku bice bifite ubushobozi bwo kwihanganira ibintu mu buryo bworoshye (ubusanzwe igabanuka rya 10-20% mu igabanuka ry'ishoti kuva ku ishoti kugeza ku ishoti) kandi ifite akamaro ku bice bidashobora kwihanganira ibintu (igabanuka rya 30-50%).
