Umshini wokugunda osetshenziselwa ukugunda okuphambene kwesitoko esiginqikayo ubizwa ngokuthiisigundi esindizayo.Ngokuthuthukiswa kwezigayo zensimbi eziginqikayo eziqhubekayo, izigayo zensimbi eziginqikayo zesigaba kanye nezigayo zokugingqa i-billet kanye nokuthuthukiswa kokukhiqiza kokugunda okundizayo, ukusetshenziswa kwezikele endizayo kuya ngokuya kuba banzi.Kunezinhlobo eziningi zezikele ezindizayo, ezisetshenziswa kakhulu: ama-disc flying shears, ama-double drum flying shears, ama-crank rotary kanye nama-pendulum flying shears.
1. Izikele zediski ezindizayo
Izikele ezinjalo endizayo ngokuvamile zisetshenziswa ezindaweni zokusebenzela ezincane zokugaya.Ifakwe phambi kombhede wokupholisa ukuze isike isitokwe esigoqayo ukuze isitokwe esigoqayo esingena embhedeni wokupholisa singabi side kakhulu;noma ifakwe phambi kwesigayo sokuphothula ukusika ucezu olugoqayo ukuze kuqinisekiswe inqubo yokugingqa yesigayo sokuqeda.uhambe kahle.I-shear endizayo yakhiwe ngamapheya amabili noma ngaphezulu ama-blades amise okwe-disc, futhi i-axis ye-disc ilingana nesivinini sensimbi.Lapho i-shear isendaweni yokuqala, insimbi iqhubekela phambili eduze kwe-inlet duct ngakwesobunxele se-shear.Lapho insimbi isebenza kuswishi yefulegi noma igayidi yokukhanya, igayidi yokungena kanye nensimbi kuchezukela kwesokudla, futhi insimbi ingena phakathi kwamadiski amabili okugunda.Ngemva kokwehliswa kwensingo engezansi, umsele ubuyisela insimbi endaweni yayo yasekuqaleni kwesokunxele, ngemva kwalokho insimbi engezansi iphinde iphakame.Ububi balolu hlobo lwe-shear endizayo ukuthi i-incision i-oblique, kodwa inomthelela omncane ekusikeni okungalungile ngaphambi kwekhanda lokusika noma umbhede wokupholisa.Ngenxa yokuthi lo mshini wokugunda unokwethenjelwa ekusebenzeni, ulula ngesakhiwo, futhi unejubane lokugunda elingaphezu kuka-10m/s, usetshenziswa kakhulu kumaworkshop amancane okugaya.
2. Izikele ezindizayo ezinezigubhu ezimbili
Isigubhu esiphindwe kabiliizikele ezindizayoasetshenziswa kakhulu ukugunda insimbi kanye steel amapuleti in motion.Umgomo wokusebenza umi kanje: Ezigubhini ezimbili ezijikelezayo, izindwani ezimbili ziqiniswe ngokukhazimulayo.Isitokwe esiginqikayo esihamba eduze kwetafula le-roller sisikwa ngama-blade amabili ahlanganayo lapho edlula phakathi kwama-roller amabili.Ijubane le-peripheral of blade kufanele libe likhulu kancane kunejubane elinyakazayo lesiqephu esigoqayo, ngaphandle kwalokho ucezu olugoqayo luzogoba emnyango lapho kugunda.Ububi balolu hlobo lokugunda okundizayo ukuthi ingxenye ayisheleli lapho kugunda izingcezu ezigoqiwe eziwugqinsi (ithonya elikhulu kakhulu ekugundani izingcezu ezincane ezigoqiwe);lapho usika amapuleti ensimbi abanzi, amandla okugunda makhulu.Ngakho-ke, lesi sigundi esindizayo sisetshenziselwa ukusika izingxenye ezincane namashidi esitokisi esiginqikayo esinesivinini esikhulu.
3. Izikele ezindizayo zeCrank rotary
Indlela yayo yokugunda yakhiwe ngendlela yokuxhumanisa amabha amane, kanti i-blade yokugunda ihamba ngendiza eseduze endaweni yokugunda futhi ibheke phezulu endaweni egoqekayo.Ngakho-ke, isigaba esinqunyiwe sesiqephu esigoqiwe siqondile.Indlela yokugunda ye-shear endizayo yenziwe ngesibambi samathuluzi, umkhono we-eccentric kanye nenduku yokushwibeka.Ukuphumula kwethuluzi kusesimweni se-lever, umkhawulo owodwa ogxilwe kumkhono we-eccentric, kanti omunye umkhawulo uxhunywe ngenduku yokushwibeka.I-swcrum ye-swing rod incike kukholamu.Uma umkhono we-eccentric (i-crank) uzungeza, umbambi wamathuluzi uyanyakaza ekuhumusheni, futhi i-blade egxilwe kusibambi samathuluzi ingaba yi-perpendicular noma cishe i-perpendicular kucezu lokusebenza.Lapho kugunda amapuleti ensimbi, i-oblique blade ingasetshenziswa ukunciphisa amandla okugunda.Ukungalungi kwalokhu kugunda okundizayo ukuthi isakhiwo siyinkimbinkimbi, izici zomthwalo oguquguqukayo wendlela yokugunda zimpofu, futhi isivinini sokunyakaza kwe-blade asikwazi ukushesha kakhulu.Ngokuvamile isetshenziselwa ukugunda amapuleti ensimbi aminyene noma amabhilidi.
4. Izikele ezindizayo ze-Pendulum
Izikena ezinjalo ezindizayo ngezinye izikhathi zisetshenziswa ezitimeleni ezinqamula ezindaweni zokusebenzela eziqhubekayo zokugaya insimbi.I-blade yale shear endizayo nayo iyahamba ekuhumusheni, futhi ikhwalithi yepuleti yokusika ingcono.Isibambi samathuluzi esingaphezulu sigxilwe kuhlaka lokushwiba.Uhlaka lokushwiba lusekelwa ekungeneni kwe-shaft eyinhloko.Kunamapheya amabili e-eccentrics ku-shaft eyinhloko, kanti enye ipheya ye-eccentric ixhunywe nendawo ephansi yethuluzi ngokusebenzisa induku yokuxhuma, futhi ingxenye engezansi yethuluzi ingaslayida ku-chute yohlaka lokushwiba.Njengoba amapheya amabili ezikhundla ze-eccentric ku-shaft eyinhloko ahluka ngo-180°, lapho i-shaft eyinhloko izungezisa, indawo yokugcina ithuluzi engenhla yehla nohlaka, futhi ithuluzi eliphansi liyakhuphuka ukuze kuqedelwe isenzo sokugunda.Kodwa-ke, inganqamula isitoko esimile kuphela.Ukuze ukwazi ukusika isitoko esigoqayo esinyakazayo, kuyadingeka ukunika amandla ifreyimu yokushwibeka ibheke phambili naphambili.Ingxenye engezansi yohlaka lokushwiba ixhunywe ngokuncike ngenduku ye-eccentric, futhi isondo eli-eccentric lifakwe ku-axle yangemuva.I-axle yangemuva ixhunywe ku-shaft eyinhloko ngamaphinikhodi, ama-racks nama-disc okuvumelanisa.Uma i-shaft eyinhloko izungeza, ifreyimu ingazulazula iye phambili naphambili nge-shaft eyinhloko njengendawo emaphakathi ngediski yokuvumelanisa, i-rack, pinion kanye ne-eccentric yokuxhuma induku ku-ekseli yangemuva.Ngalesi sikhathi, umbambi wethuluzi uyanyakaza ekuhumusheni ukuze abone umsebenzi wokugunda we-pendulum flying shear.Indima yomshini wokugunda endaweni yokugaya ayiyona indawo ebalulekile, kodwa idlala indima ebalulekile ekunembeni nasekumeni komkhiqizo osuphelile.Izinhlobo ezahlukene zezigayo zidinga ukukhetha amashekeli endizayo ahambisanayo, ukuze wonke umugqa wokukhiqiza ukwazi ukufeza umgomo.usayizi nokunemba.
