Funso: Nchifukwa chiyani chosindikizira chimatchedwa press brake?Bwanji osapanga bender kapena chitsulo choyambirira?Kodi zikukhudzana ndi flywheel yakale pamabuleki amakanika?Flywheel inali ndi mabuleki, monga momwe ziliri pagalimoto, zomwe zimandilola kuyimitsa kuyenda kwa nkhosa yamphongo isanayambe kupanga pepala kapena mbale, kapena kuchepetsa liwiro la nkhosa yamphongo popanga.Chiboliboli chosindikizira chinali ngati chosindikizira chokhala ndi brake.Ndakhala ndi mwayi wokhala ndi imodzi kwa zaka zingapo, ndipo kwa zaka zambiri ndinkaganiza kuti n’chifukwa chake dzina la makinawo ndi mmene lilili, koma sindikudziwa kuti n’zoona.Sizikumveka bwino, poganizira mawu oti "brake" akhala akugwiritsidwa ntchito kutanthauza kupindika kwachitsulo kwanthawi yayitali makina oyendera magetsi asanabwere.Ndipo kusweka kwa atolankhani sikungakhale kolondola, chifukwa palibe chomwe chasweka kapena kusweka.
Yankho: Nditasinkhasinkha za nkhaniyi kwa zaka zambiri, ndinaganiza zofufuza.Pochita izi ndili ndi yankho komanso mbiri yakale yoti nditumizenso.Tiyeni tiyambe ndi momwe zitsulo zachitsulo poyamba zinkapangidwira komanso zida zomwe zinagwiritsidwa ntchito pokwaniritsa ntchitoyi.
Kuchokera ku T-stakes kupita ku Cornice Brakes
Makina asanabwere, ngati wina akufuna kukhonda chitsulo amalumikiza kachidutswa kakang'ono kachitsulo ku nkhungu kapena mtundu wa 3D wa mawonekedwe omwe akufuna;nthiti;chidole;kapena ngakhale thumba lopanga, lomwe linali lodzaza ndi mchenga kapena kuwombera.
Pogwiritsa ntchito T-stake, nyundo ya mpira, lamba wamtovu wotchedwa mbama, ndi zida zotchedwa spoons, akatswiri aluso amamenya chitsulocho kuti chikhale chomwe akufuna, monga ngati chapachifuwa cha zida zankhondo.Inali ntchito yamanja kwambiri, ndipo ikuchitidwabe mpaka pano m'malo ambiri ogulitsa magalimoto ndi zojambulajambula.
"Brake" yoyamba monga tikudziwira inali cornice brake yovomerezeka mu 1882. Inadalira tsamba logwiritsidwa ntchito pamanja lomwe linkakakamiza chitsulo chomangika kuti chipirire molunjika.M'kupita kwa nthawi izi zasintha kukhala makina omwe timawadziwa lero monga mabuleki amasamba, mabuleki a bokosi ndi ma pan, ndi makina opinda.
Ngakhale kuti matembenuzidwe atsopanowa ndi ofulumira, ogwira mtima, komanso okongola mwaokha, samafanana ndi kukongola kwa makina oyambirira.Chifukwa chiyani ndikunena izi?Zili choncho chifukwa makina amakono sapangidwa pogwiritsa ntchito zida zachitsulo zopangidwa ndi manja zomwe zimagwirizanitsidwa ndi zidutswa za oak zogwiritsidwa ntchito bwino kwambiri.
Mabuleki oyambirira osindikizira amphamvu anaonekera zaka pafupifupi 100 zapitazo, kuchiyambi kwa zaka za m’ma 1920, okhala ndi makina oyendetsedwa ndi ntchentche.Izi zidatsatiridwa ndi mitundu yosiyanasiyana ya ma hydromechanical ndi hydraulic press brakes mu 1970s ndi mabuleki osindikizira amagetsi mu 2000s.
Komabe, kaya ndi brake yosindikizira makina kapena mabuleki apamwamba kwambiri amagetsi, zidatheka bwanji kuti makinawa azitchedwa brake yosindikizira?Kuti tiyankhe funsoli, tifunika kufufuza za etymology.
Kuthyoka, Kusweka, Kusweka, Kuthyoka
Monga mneni, kuthyoka, kuthyoka, kuthyoka, ndi kuthyola zonse zimachokera ku mawu akale omwe amatsogolera chaka cha 900, ndipo onse amagawana chiyambi kapena muzu womwewo.Mu Chingelezi Chakale chinali brecan;m’Chingelezi Chapakati chinali chophwanyika;m’Chidatchi chinasweka;m’Chijeremani anali brechen;ndipo m'mawu a Gothic anali brikan.Mu Chifalansa, brac kapena bras amatanthauza lever, chogwirira, kapena mkono, ndipo izi zidakhudza momwe mawu oti "brake" adasinthira kukhala momwe alili pano.
Tanthauzo la zaka za m’ma 1500 la mabuleki linali “chida chophwanyira kapena kugunda.”Pamapeto pake, mawu oti "brake" adayamba kufananizidwa ndi "makina," omwe adachokera ku makina omwe amagwiritsidwa ntchito kuphwanya mbewu ndi ulusi wa mbewu.Kotero mu mawonekedwe ake ophweka, "makina osindikizira" ndi "press brake" ndi amodzi mofanana.
Old English brecan idasinthika kukhala break, kutanthauza kugawa mwamphamvu zinthu zolimba kukhala magawo kapena zidutswa, kapena kuwononga.Komanso, zaka mazana angapo zapitazo gawo lapitalo la "brake" "linasweka."Zonsezi ndikunena kuti pamene muyang'ana pa etymology, "kuswa" ndi "kuswa" zimagwirizana kwambiri.
Mawu oti “brake” monga momwe amagwiritsidwira ntchito popanga zitsulo zamakono, amachokera ku verebu lachingerezi la Middle English breken, kapena break, limene limatanthauza kupindika, kusintha kumene akulowera, kapena kupatuka.Mukhozanso “kuthyola” pamene munakokera kumbuyo chingwe cha uta kuti muponyere muvi.Mungathe ngakhale kuthyola kuwala kwa kuwala mwa kulitembenuza ndi galasi.
Ndani Anayika 'Presse' mu Press Brake?
Tsopano tikudziwa komwe mawu oti "brake" amachokera, nanga bwanji atolankhani?Inde, pali matanthauzo ena osagwirizana ndi mutu wathu wamakono, monga utolankhani kapena kusindikiza.Kumbali iyi, kodi liwu lakuti “kusindikiza” —kulongosola makina amene timawadziŵa lerolino—amachokera kuti?
Cha m'ma 1300, "presse" idagwiritsidwa ntchito ngati dzina lomwe limatanthawuza "kuphwanya kapena kudzaza."Pofika chakumapeto kwa zaka za m’ma 1400, “chofinyira” chinali chitasanduka chida chofinyira zovala kapena kufinyira madzi a mphesa ndi azitona.
Kuchokera apa, "kusindikiza" kudasinthika kutanthauza makina kapena makina omwe amagwiritsa ntchito mphamvu pofinya.Pogwiritsa ntchito makina opangira nsalu, nkhonya ndi kufa zimatha kutchedwa "zosindikizira" zomwe zimagwiritsa ntchito mphamvu pazitsulo zachitsulo ndikupangitsa kuti ipindike.
Kupinda, ku Brake
Kotero apo izo ziri.Mneni “brake,” monga momwe amagwiritsidwira ntchito m’mashopu azitsulo, amachokera ku verebu lachingerezi la Middle English lomwe limatanthauza “kupinda.”Pakugwiritsa ntchito masiku ano, brake ndi makina omwe amapindika.Kwatirani izo ndi chosinthira chomwe chimafotokoza zomwe zimayendetsa makinawo, ndi zida ziti zomwe zimagwiritsidwa ntchito popanga chogwirira ntchito, kapena ndi mitundu yanji yopindika yomwe makinawo amapanga, ndipo mumapeza mayina athu amakono amitundu yosiyanasiyana yachitsulo ndi makina opindira mbale.
Mabuleki a cornice (amatchedwa cornices yomwe imatha kupanga) ndi msuweni wake wamakono wa mabuleki amagwiritsa ntchito tsamba lopendekera m'mwamba, kapena apuloni, kuti ayendetse.Bokosi ndi poto brake, yomwe imatchedwanso kuti chala brake, imapanga mitundu yopindika yomwe imafunikira kupanga mabokosi ndi mapoto popanga zitsulo zachitsulo kuzungulira zala zogawanika zomangika kunsagwada zakumtunda kwa makina.Ndipo potsirizira pake, mu makina osindikizira, makina osindikizira (ndi nkhonya zake ndi kufa) amayendetsa braking (kupindika).
Pamene ukadaulo wopindika ukupita patsogolo, tawonjezera zosintha.Tachoka pa mabuleki osindikizira amanja kupita ku ma mechanical press brakes, hydromechanical press brakes, hydraulic press brakes, ndi electric press brakes.Komabe, mosasamala kanthu kuti mumatcha chiyani, brake yosindikizira yangokhala makina ophwanyira, kufinya, kapena—chifukwa cha zolinga zathu—kupinda.
