Ku Bolton, Lancashire, England fakitale yopanga ma trailer a Indespension, zokolola zachitsulo zodulira zitsulo zachulukirachulukira kutsatira kusinthidwa kwa Disembala 2016 kwa makina a CO2 laser-powered ndi Bystronic ByStar Fiber 6520 fiber laser profiling center yomwe imawononga pafupifupi £800,000 (pafupifupi $1.3 miliyoni; CHITHUNZI 1). Laser ya 4kW fiber ili ndi 6.5 × Bedi la 2m, ndikupangitsa kukhala makina akulu kwambiri a fiber omwe amaperekedwa mpaka pano pamsika waku UK
FIGURE 1. Ndi ByStar Fiber 6520 fiber laser system, nayitrogeni amagwiritsidwa ntchito ngati gasi wodulira pazinthu zonenepa mpaka 5mm, pamwamba pake pomwe mpweya wotsika mtengo umagwiritsidwa ntchito; pali kusiyana pang'ono mu khalidwe la odulidwa
Woyang'anira zogula ku Indespension Steve Sadler adati, "Timadula kwambiri 43A ndi pre-galv mild steel, kuphatikiza aluminiyumu, kuchokera 1mm mpaka 12mm wandiweyani. Kufikira 3mm, fiber laser imadula katatu kuposa CO2. Imawuluka muzitsulo za 1mm, imapanga mabowo 10 / s. Ubwinowu umakhalapo pamene makulidwe akuchulukirachulukira, koma chonsecho ByStar imathamanga kuwirikiza kawiri pamageji onse omwe timapanga. Pa sitiroko, yathetsa vuto la fakitale yathu yomwe idayamba chifukwa cha makina a CO2 osatha kuyenderana ndi kuchuluka kwa ntchito yathu yodula laser. "
Fibre laser idagulidwa mosinthana pang'ono kuti ikhale yofanana ndi mphamvu ya Bystronic CO2 ku Indespension yomwe idaperekedwa mu 2009. Sadler adatsimikizira kuti mtengo wabwino unakwaniritsidwa pamakina akale, ngakhale adagwira ntchito mpaka maola 20 patsiku, ndikuwunikira kusungitsa mtengo ngati mwayi wogula zida kuchokera kwa wopanga uyu.
Pachiyambi, chifukwa chachikulu ndalama mu laser kudula anali kukwaniritsa digiri yaikulu kulamulira m'nyumba kupanga ngolo ndi kupulumutsa ndalama kuika ntchito kwa pepala subcontractors zitsulo. Chinthu chinanso chofunikira chinali kuwongolera kachitidwe ka prototyping ndi kapangidwe kake ndikubweretsa zinthu zatsopano kumsika mwachangu.
"Zisanafike chaka cha 2009, panthawi yopanga zinthu timayenera kugula magawo amodzi, awiri, kapena atatu azitsulo zazitsulo," adatero Sadler. “Ma subcontractors sadali ofunitsitsa kupanga zochepa chonchi, ndiye mtengo wake umakhala wokwera ndipo zimawatengera milungu inayi mpaka sikisi kuti apereke ma prototypes. Ngati tidafunikira kusintha kapangidwe kake ndikubwereranso kwa subcontractor kuti tipeze ma prototypes ena—zitha kukhala chinthu chophweka ngati gulu latsopano la alonda amatope—omwe atha kuwonjezera mwezi wina kapena apo. Tsopano, titha kupanga magawo m'nyumba m'masiku ochepa, kuchepetsa nthawi yotsogolera ya ngolo yatsopano kuchokera miyezi isanu ndi umodzi kapena isanu ndi iwiri mpaka kuchepera isanu, kapena kalavani yosinthidwa kuchokera miyezi itatu kapena inayi mpaka kuchepera iwiri. "
Sadler adanenanso kuti zaka khumi zapitazo, ma trailer ochepa anali ndi zida zodulira laser, pomwe masiku ano amagwiritsidwa ntchito kwambiri. Zoonadi, mankhwala amapangidwa mozungulira mphamvu ndithu amakono laser kudula makina. Ubwino umodzi ndi woti makinawo amakhala olondola kwambiri kotero kuti zigawo zake zimagwirizana ndendende komanso mwachangu panthawi yophatikiza, popanda kufunika kophatikiza nthawi.
Ubwino winanso ndikuti makina amathamanga kwambiri, makamaka ndi fiber laser, kuti ndi njira yotsika mtengo yochotsera kulemera kwa zigawo zake pophatikiza mabowo ndi mipata yambiri. Zingakhale zovutirapo kwambiri kotero kuti sizingagwire ntchito pamanja.
Selo yodulira laser imagwira ntchito usana ndi usiku komanso kuzimitsa nthawi yachilimwe, maola 18 mpaka 20 patsiku, masiku asanu pa sabata. Kwa nthawi yotsala ya chaka, imayendetsa masinthidwe atsiku ndikuwunikira kwa maola 10 mpaka 12 patsiku.
Indespension idaganiza zosiya kukhazikitsa zida zodzipangira okha chifukwa imapanga makulidwe osiyanasiyana amasamba, zomwe zimapangitsa kuti pakhale vuto. Kusiyanasiyana kwa zigawo zake ndi zazikulu, kuyambira kupitirira 5.8m pansi. Kupezeka kwa opareshoni ndikofunikira kuti azitha kuyang'anira kusiyanasiyana, kotero kachitidwe kanu, kachitidwe ka suction-pad kumagwiritsidwa ntchito ponyamula mapepala (CHITHUNZI 2).
FIGURE 2. Kugwira ma sheet ndi kutseka pa tebulo la ByStar Fiber 6520's shuttle table kumachitidwa pamanja ku Indespension pogwiritsa ntchito chipangizo chonyamulira pad.
Izi zimabweretsa vuto kukampani, komabe, ngati kupanga kuphatikizira chisa cha magawo ochepa chabe ndipo amadulidwa kuchokera pa pepala locheperako. Kudulira kumakhala kofulumira kwambiri mu makina a fiber laser kotero kuti wogwiritsa ntchito alibe nthawi yomaliza kugwedeza zigawo za chigoba cham'mbuyo chisanafike pepala lopangidwa ndi makinawa, kapena kuyika chopanda chotsatira patebulo la shuttle.
Chifukwa chake, kampaniyo ikuganiza zophatikizira ma tag ang'onoang'ono m'mapulogalamu ena odulira zitsulo kuti magawo ojambulidwa akhalebe olumikizidwa ndi chigoba, kulola kuti pepala lonse lokonzedwa kuti lisamutsidwe ku siteshoni yakunja, komwe wogwira ntchito wina angathandize kuchotsa zigawozo.
Pazigawo zazitsulo zopangidwa ndi laser zomwe zimapita m'ma trailer a Indespension, 80% amafunikira kupindika. Chifukwa chake, makina oyamba a laser atayikidwa, chosindikizira cha tandem kuchokera kwa ogulitsa omwewo chinaperekedwanso (CHITHUNZI 3)
FIGURE 3. Imodzi mwama trailer a mbewu ya Indespension, yotchedwa Digadoc, yomwe ikuwonetsa kuchuluka kwa zida zodulidwa ndi laser ndi zopindika zofunika pazigawo zake zachitsulo.
Pali zopindulitsa pakupeza makina odulira laser ndikusindikiza mabuleki kuchokera kwa ogulitsa omwewo chifukwa onse amagwiritsa ntchito pulogalamu yomweyo ya BySoft 7. Pamene chigawo chatsopano chakonzedwa mu dongosolo Indespension SolidWorks CAD ndi zimagulitsidwa ku Bystronic ulamuliro mapulogalamu, amene palokha muli amphamvu 3D CAD/CAM magwiridwe antchito, chitsanzo amapanga pulogalamu laser kudula ndi zinayendera kwa kupinda chigawo, kuphatikizapo backgauge udindo ndi dongosolo chida, potero kuchepetsa kuchedwa ndi downtime.
Mapulogalamu omwewo, omwe ali ndi mphamvu zofananira zonse, ali ndi udindo wokhala ndi chisa chochuluka cha zigawo kuchokera pa pepala, kupanga mapulani odulira ndikupereka chithunzithunzi cha ndondomeko yopangira zinthu, kuphatikizapo kupeza mwamsanga kupanga ndi deta yamakina.
"Ndife odzipereka kutsogolera msika pankhani yazatsopano, zabwino, komanso zidziwitso zachilengedwe," adatero Sadler. "Kupeza kwa Bystronic fiber laser kumatithandiza kuti tikwaniritse zolingazi, komanso kupereka chiwonjezeko chofunikira kwambiri pakupanga. Zikuwonetsanso kudzipereka kwathu pakupanga ku UK, komwe ndi gawo lofunikira pamalingaliro amakampani athu. "
