Kodi Modular Design Imachepetsa Bwanji Nthawi Yosintha Nkhungu?

Nthawi ndi ndalama yomanga. Mphindi iliyonse yomwe mzere wopanga umayimitsidwa kuti asinthe nkhungu ndi mphindi yakutaya zokolola. Mitundu yachikhalidwe ya monolithic ndi yolemetsa, yolemetsa, ndipo imafuna njira zambiri zomangirira ndi kuyanjanitsa, nthawi zambiri zimatenga mphindi 45 mpaka 90 kuti zisinthe. Mosiyana ndi izi, dongosolo la nkhungu la konkriti la nkhungu limapangidwa kuti lifulumire. Mfundo yayikulu ndikulekanitsa chimango cha nkhungu (chizindikiro chothandizira chomwe chimalowa mu makina otchinga) kuchokera pamakina oyika (zigawo zomwe zimapanga konkire). Izi zimathandiza kuti chimango cholemera, chokulirapo chikhale chotsekeka pomwe zoyika zopepuka ndizosinthana. Fakitale yathu yasintha lingaliro ili kukhala hydraulic quick-clamp system yomwe imatha kusintha nkhungu kwathunthu mkati mwa mphindi 5, popanda kufunikira kwa zida zapadera.

Njira yoyendetsera liwiroli ndikuphatikiza zinthu zitatu zazikuluzikulu: mawonekedwe ofananirako, ma hydraulic clamping, ndi machitidwe owongolera. Choyamba, timapanga mafelemu athu onse opangidwa ndi nkhungu okhala ndi mawonekedwe oyambira padziko lonse lapansi omwe amagwirizana ndi miyezo yapadziko lonse lapansi yama block machine (ASAE, DIN, kapena ISO). Izi zikutanthauza kuti chimango chimakwanira makina aliwonse ogwirizana. Chachiwiri, hydraulic clamping system imagwiritsa ntchito ma actuators anayi kapena asanu ndi limodzi omwe amalumikizana nthawi imodzi ndikutseka nkhunguyo. Ma clamping awa amawongoleredwa ndi PLC yamakina, kuwonetsetsa kuti nthawi zonse kumangogwira mwamphamvu. Chachitatu, dongosolo lowongolera motsogozedwa limagwiritsa ntchito zikhomo zolondola ndi ma cones odzipangira okha omwe amangoyika nkhungu yatsopano mkati mwa kulolerana kwa +/- 0.15 mm, kuthetsa kufunikira kwa kuwongolera pamanja. Pakafunika kusintha nkhungu, wogwiritsa ntchitoyo amangotulutsa zingwezo, kutulutsa nkhungu yakaleyo pabedi lodzigudubuza, amalowetsa yatsopano, ndikuyika zingwezo. Njira yonseyi ndi yodziwika bwino ndipo imatha kuchitidwa ndi wogwiritsa ntchito m'modzi. Kuthekera kofulumira kumeneku kumapangitsa fakitale kupanga mizere ingapo yazinthu munthawi imodzi, kuyankha pakufunika kwa nthawi yeniyeni yomanga.

Kuti muwongolere zomwe zikuchitika, lingalirani kufananitsa kotsatiraku kwa zochitika zanthawi yocheperako:

Deta ikuwonekera bwino: kusintha kwa mphindi 90 kumachepetsedwa kukhala mphindi 7 zokha. Kwa fakitale yomwe imasintha nkhungu katatu patsiku, izi zimatanthawuza kupitilira maola anayi owonjezera tsiku lililonse. Kupitilira chaka chimodzi, izi ndi maola opitilira 1,000 atha kuyambiranso. Koma liwiro si mwayi wokha. Kulondola kwa ma modular system kumatanthawuza kuti makinawo ayambiranso kupanga ndi mtundu wa block nthawi yomweyo, popanda kukana "kutentha" komwe nthawi zambiri kumatsata kusintha kwamanja. Kulondola uku ndikofunika kwambiri kuti mukhalebe ndi kulolerana kolimba kofunikira pakulumikizana ndi kukongoletsa midadada. Popereka liwiro popanda kupereka khalidwe labwino, makina opangira nkhungu amakhala chida chothandizira bizinesi, kulola kuti chomeracho chitengere maoda ang'onoang'ono, opangidwa mopindulitsa - luso lomwe likufunidwa kwambiri ndi msika wamakono wa zomangamanga.

Kodi Zochita Zaukadaulo za Modular Molds ndi ziti?

Ngakhale mapangidwe a modular amapereka kusinthasintha kwapadera, sikuyenera kusokoneza zofunikira za nkhungu: kulimba, kulondola, ndi moyo wautali. Ma modular amaumba athu samangokhalira "modular" m'dzina; amapangidwa molingana ndi miyezo yofananira ndi nkhungu zathu zokhazikika. Zoyikapo, zomwe zimakhala ndi vuto lalikulu la abrasion ya konkriti, zimapangidwa kuchokera ku zitsulo zolimba kwambiri (58-62 HRC) zokhala ndi chromium plating kuti muchepetse kuvala komanso kutulutsa konkriti. Mafelemu amapangidwa kuchokera ku heavy-duty structural zitsulo, kuchepetsa kupanikizika kuti zisawonongeke. Izi zimatsimikizira kuti ma modular system samapereka ntchito kuti zitheke. Fakitale yathu imayang'anira nkhungu iliyonse pakupanga ndi kuyesa kokhazikika, kuphatikiza kuyang'ana mozama pamakina oyezera (CMM) komanso kuyesa kwamadzi othamanga kwambiri kuti atsimikizire kusindikiza.

Nayi kufotokozedwa mwatsatanetsatane kwaukadaulo wofunikira wamakina athu a modular mold:

Izi siziri manambala okha pa pepala la deta; amatanthauzira malire ogwirira ntchito ndi kuthekera kwa nkhungu. Mwachitsanzo, kusankha kwa chitsulo cha 1.2379 chokhala ndi chrome plating ndikofunikira kuti pakhale kutha kwapamwamba pamizere yambiri. Chikombole chomwe chimavala mosagwirizana chidzatulutsa midadada ndi miyeso yosagwirizana, zomwe zimayambitsa mavuto panthawi yomanga.

Akavala, zoyikazo zimatha kukonzedwanso mopanda chimango, ndikupulumutsa mpaka 40% ya mtengo wa nkhungu yatsopano. Kuthekera kokonzanso uku ndichinthu chofunikira kwambiri pa ROI yanthawi yayitali ya ma modular system. Mwa kuyika ndalama mu chimango chokhazikika kamodzi, mutha kungosintha kapena kusinthanso zoyikazo ngati pakufunika, ndikusunga dongosololo kukhala "labwino ngati latsopano" kwazaka zambiri.

Kodi Zolowetsa Zosinthana ndi Zigawo Zimathandizira Bwanji Kusiyanasiyana Kwamapangidwe?

Zomangamanga zikuchulukirachulukira kufuna chidwi chowoneka komanso zovuta muzomanga za konkriti. Masiku a monotonous imvi rectangular midadada akuzimiririka; msika tsopano umafuna malo ojambulidwa, ma geometri olumikizana, ndi mbiri zovuta zamakhoma ndi mayendedwe. The modular nkhungu ndiye chothandizira kusintha kamangidwe kameneka. Mfundo yayikulu ndikutha kusinthanitsa zoyikapo pawokha kuti mupange mbiri yatsopano ya block, mawonekedwe, ndi mapatani. Choyikapo chipika chokhazikika cha 200x200x400 chingathe kusinthidwa ndi choyikapo cholimba cha 150x150x300 kapena chipika chokongoletsera chokhala ndi maluwa, zonse mkati mwa chimango cholimba chomwechi. Izi sizongosintha kukula kwake; ndizokhudza kusintha magwiridwe antchito ndi kukongola kwa chinthu chomaliza. Dongosolo lathu la nkhungu lokhazikika limakhala ndi mitundu itatu yayikulu ya zinthu zomwe zimasinthikana: zoyika pabowo (za mawonekedwe a block), ma core pin (popanga mabowo kapena voids), ndi mbale zakumaso (zopaka mawonekedwe apamwamba).

Ganizirani zochitika za ntchito yomanga yomwe imafuna khoma lonyamula katundu lomwe lili ndi makona apadera. Mwachizoloŵezi, kontrakitala amafunikira nkhungu yapadera pakona, yosiyana ya khoma lolunjika, ndi ina ya lintel block. Ndi ma modular system, chimango chimodzi ndi zoyikapo zimatha kupanga zigawo zonsezi. Njirayi ndi yosavuta: zibowo zomwe zimafunikira kupanga mawonekedwe angodya zimayikidwa ndi zoikamo zoyenera. Dongosolo loyang'anira pamakina otchinga limatha kukonzedwanso kuti lipange mawonekedwe enaake a midadada kuchokera pamphasa imodzi, mwachitsanzo, kuphatikiza zosalala komanso zojambulidwa pakhoma. Kuthekera uku kumapitilira kupitilira ma geometry chabe kuphatikiza chithandizo chapamwamba. Posintha mbale za nkhope, mawonekedwe ofanana a block atha kuperekedwa kutha kosalala, kugawanika kwa nkhope (zoyipa), kapena kumalizidwa (zopindika). Kusinthasintha kumeneku kumapangitsa kuti chomera chimodzi chizitha kugulitsa magawo angapo amsika - okhala, malonda, ndi mawonekedwe - ndi ndalama imodzi.

Sayansi yazinthu zomwe zimayika izi ndizofunikanso. Pakupanga kwapamwamba kwambiri kwa midadada yokhazikika, zoyikapo nthawi zambiri zimapangidwa kuchokera kuzitsulo zolimba. Kwa midadada yapadera yaifupi (mwachitsanzo, pulojekiti yeniyeni yomanga), timapereka mwayi wogwiritsa ntchito kuikapo urethane. Izi ndizotsika mtengo kwambiri kupanga ndipo zitha kupangidwa mwachangu, zomwe zimawapangitsa kukhala abwino pamakina ocheperako. Ntchitoyo ikatha, zoyikapo urethane zitha kusungidwa ndikugwiritsidwanso ntchito ngati mapangidwewo abwerezedwa, kapena kungosinthidwanso. Kuthekera kumeneku kopangira ndalama zopangira makonda ndizosintha masewera kwa omanga ndi opanga omwe akufuna kupanga chizindikiritso chapadera pama projekiti awo. Imachotsa chotchinga cha mtengo wa zida, zomwe mwamwambo zimapanga midadada ya konkriti yotsika mtengo. Dongosolo la nkhungu la modular, lomwe limalowetsamo kusinthana, limakhazikitsa demokalase, kulola kuti ntchito iliyonse yomanga ikhale ndi zinthu zapadera, zapamwamba za konkriti popanda kuphwanya bajeti.

Kodi Mold Flexibility Imakulitsa Bwanji Project Economics ndi ROI?

Liwiro la magwiridwe antchito ndi kusinthika kwa ma modular nkhungu ndizodabwitsa, koma funso lomwe limafunikira kwenikweni ndilakuti: "Kodi izi zikutanthauza chiyani pa mfundo yanga?" Phindu lazachuma la modular mold system ndi lamitundu yambiri ndipo limapitilira pamtengo wogula woyamba. Chochititsa chidwi kwambiri ndi kuchepa kwa zinthu za nkhungu. M'malo mogula ndikusunga nkhungu yosiyana yamtundu uliwonse wa block, makina opangira ma modular amakulolani kukhala ndi mafelemu apamwamba kwambiri komanso katundu woyika. Izi zimachepetsa ndalama zoyambira zoyambira pa nkhungu ndi 30-50%. Kwa opanga ma block okhala ndi mizere 20 yazinthu zosiyanasiyana, ndalama zimatha kukhala zochulukirapo.
