Tiyeni tidutse phokosolo. Anthu ambiri akamva 'zigawo zoponyamo zamphamvu yokoka', amajambula zithunzi za aluminiyamu zopanda chilema zomwe zikutuluka pamzere. Ndilo mtundu wa kabukuka. Chowonadi pansi ndikukambirana kosalekeza pakati pa cholinga cha mapangidwe, machitidwe achitsulo, ndi fizikiki yolimba ya nkhungu yokhazikika. Sikuti kungothira chitsulo m’mphako yachitsulo; ndikuwongolera kutentha, kuyembekezera kutsika m'malo olakwika, ndi kudziwa pamene mapangidwe akupempha chilema.
Malo Osamvetsetseka Pakatikati
Gravity die casting imakhala pamalo osangalatsa awa, omwe nthawi zambiri sagwiritsidwa ntchito molakwika pakati pa kuponya mchenga ndi kuponyera kwamphamvu kwambiri. Ndikuwona zofotokozera zimabwera nthawi zonse pomwe wina amafuna kukhazikika kokhazikika komanso kutha kwa nkhungu yokhazikika, koma ndizovuta zamkati za mchenga. Izo sizimagwira ntchito monga choncho. Chitsulo chimafuna njira yoyenda ndi kudyetsa. Simungakhale ndi zigawo zolemetsa kumbuyo kwa makoma opyapyala-ndiwo malo ocheperako omwe akuyembekezera kuchitika. Chikombole, pokhala chitsulo chosasunthika, sichikhululuka.
Tidaphunzira izi movutikira zaka zambiri mmbuyo pa bulaketi ya ma hydraulic manifold. Chojambula cha kasitomala chinali ndi mawonekedwe okongola, ophatikizika okhala ndi chikwama chochindikala chokhazikika moyandikana ndi kamphepo kakang'ono. Zowoneka bwino pa CAD. Zoona zake, chikwamacho chinalimba chomaliza, choyamwa chitsulo kuchokera ku gawo lopyapyala lomwe linali lolimba kale, ndikusiya mphambano ya porous, yofooka. Kukonza sikunali kungosintha kutsanulira; zinatanthauza kubwereranso kwa wopanga ndikuwonjezera nthiti yobisika kuti ikhale ngati njira yodyera. Ndilo tsiku ndi tsiku: gawo la engineering.
Apa ndipamene zinachitikira foundry ndi njira zosiyanasiyana kulipira. Kampani ngati Malingaliro a kampani Qingdao Qiangsenyuan Technology Co., Ltd., ndi mbiri yawo mu chipolopolo ndi kupanga ndalama, ali ndi mwendo pamwamba apa. Amamvetsetsa machitidwe olimba kuchokera kuzinthu zovuta kupanga. Kugwiritsa ntchito chidziwitso chimenecho ku mphamvu yokoka kufa kumatanthauza kuti iwo sali chabe odzaza nkhungu; akuganiza mmene chitsulocho chimayendera ndi kuziziritsa pochoka. Mutha kuwona njira yawo pa portal yawo tsngtaocnc.com-ndi za njira yoyenera ya gawo, osati kungogulitsa luso limodzi.
Zinthu Zakuthupi Sizongoganizira Mosaganizira
Aluminiyamu imapeza ulemerero wonse, koma masewerawa amasintha kwathunthu ndi ma alloys ena. Tikuyankhula mphamvu yokoka imafa poponya ziwalo mkuwa, kapena ma aloyi ena a magnesium. Iliyonse ili ndi sewero lake. Aluminium A356? Mukuyang'anira kusinthidwa kwa strontium kwa silicon ya eutectic ndikuchita ndi kujambula kwa hydrogen. Thirani mwamphamvu kwambiri, ndipo mumawotcha mu porosity chitsulo chisanayambe kuzizira.
Koma nenani kuti mukufuna gawo mu aloyi wopangidwa ndi faifi tambala kuti mugwiritse ntchito kutentha kwambiri. Mwadzidzidzi, kutopa kwamafuta pa nkhungu yachitsulo ya H13 kumakhala njira yovuta. Kutentha kwa kutentha kuchokera ku 1500 ° C + motsutsana ndi aluminiyumu pa 700 ° C ndi nkhanza. Moyo wa nkhungu umachepa. Mtundu wanu wamtengo umatuluka pawindo. Apa ndipamene kutchulidwa kwa QSY kugwira ntchito ndi ma alloys apadera monga opangidwa ndi nickel sikungotanthauza chipolopolo. Zikutanthauza kuti amayenera kuthana ndi vuto la kasamalidwe ka matenthedwewa, mwina kudzera mu zokutira zapadera za nkhungu kapena njira zoziziritsira zowongolera. Ndi ligi yosiyana ndi kutulutsa nyumba za aluminiyamu.
Ndikukumbukira pulojekiti yomanga sensa nyumba mu duplex zitsulo zosapanga dzimbiri. Zolemba za corrosion zinali zolimba. Dongosolo la mphamvu yokoka lidatipatsa kutha kwapamwamba komanso kusasinthika komwe kumafunikira, koma kuwongolera bwino kwa ferrite-austenite kudzera mukuzizira koyendetsedwa ndi nkhungu yokhazikika kunali kowopsa. Tidadutsamo mbiri yozungulira yotentha pa nkhungu tisanakhale ndi microstructure yosasinthika. Chinali chikumbutso kuti 'kufa' mu mphamvu yokoka ndi chida chowongolera kutentha ngati chida choumba.
The Machining Handshake
Uku ndiye kupumula komwe oyambitsa masewera ambiri amasokonekera. A mphamvu yokoka gawo silikhala chinthu chomaliza. Ndi pafupi-mawonekedwe-ukonde opanda kanthu akulunjika molunjika kwa CNC vise. Ngati oyambitsa sakumvetsetsa makina, mumamva mitundu iwiri yamutu: malo osagwirizana omwe amawonongeka, kapena malo obisika obisika kuchokera ku kuzizira kosagwirizana komwe kumaphwanya zida.
Synergy ndi yofunika kwambiri. Pamene nyumba yoponyera imayendetsanso mizere ya CNC, monga QSY imachitira, pali njira yobwereza. Katswiri wamakina amauza woyambitsayo kuti kuponyedwa kwachitatu kulikonse kumakhala ndi malo ovuta pa flange inayake. Choyambiracho chimayang'ana kuzizira kwa nkhungu ndikuzindikira kuti mzere umodzi wamadzi watsekedwa pang'ono, ndikupanga malo otentha am'deralo ndikusintha ma microstructure. Vuto lathetsedwa pagwero. Popanda kuphatikiza kumeneko, ndimasewera olakwa pakati pa ogulitsa ndi ogulitsa makina.
Timaumirira pakuwunika koyamba komwe kumaphatikizapo kuyesa makina. Ponyani mtanda, kokerani chitsanzo, ndikuchiyika pamphero. Kodi imakhazikika bwino? Kodi makina amadziwiratu? Lipoti laling'ono lochokera ku CMM ndi chinthu chimodzi, koma phokoso la wodula ndi mtundu wa chip zimafotokoza nkhani yeniyeni. A zabwino yokoka kufa akuponya samangokumana kusindikiza kulolerana; imapangidwa ngati chinthu chodziwika bwino.
Zikadzalakwika (Ndipo Zidzatero)
Kusanthula kulephera ndi kumene mumaphunziradi. Ndawonapo mbali zikudutsa X-ray ndikulowetsa utoto, kenako ndikulephera kuyesa kutopa. Mng'alu nthawi zonse umayambira pamalo omwe amawoneka oyera. Nthawi zambiri, si vuto lalikulu, koma khola losawoneka bwino la okusayidi kapena gulu laling'ono la micro-shrinkage lomwe limapangidwa pakudzaza. Ndi kutsanulira kwa mphamvu yokoka, ngati khomo silili loyenera kuti lipangitse kutuluka kwa laminar, mumapinda pakhungu la oxide kuchokera pamwamba pa mtsinje wosungunuka. Amakhala woyambitsa mng'alu wangwiro wokwiriridwa mkati mwa khoma.
China chapamwamba ndi kupotoza. Mumakoka gawo mu nkhungu, imayang'ana pa CMM. Pambuyo pa chithandizo cha kutentha (T6 ya aluminiyamu, tinene), imapindika. Zotsalira za kuzizira kosagwirizana mu nkhungu zolimba zimatulutsidwa. Tsopano mwakakamizika kuyesa kuwongola gawo lotenthedwa, lomwe ndi njira yabwino yodziwitsira zovuta zatsopano. Yankho lake nthawi zambiri limakhala pamapangidwe a nkhungu-kuzizira kofananira, nthawi zina ngakhale malo abwino otsekera kuti azitha kukhazikika kutsogolo.
Awa sizovuta zamaganizidwe. Ndiwo maola omwe amathera pa shakeout, kukanda mutu wanu, kusinthana ma thermocouples, ndi kusuntha mabeseni otsanulira. Cholinga ndi njira yolimba, osati chitsanzo chabwino. Mtengo weniweni wa ogulitsa ndi momwe amachitira ndi zovuta zosapeŵeka izi. Kodi ali ndi zitsulo zozama komanso zozama kuti azindikire ndikukonza, kapena amangoponya gulu lina ndi chiyembekezo?
The Realistic Application Sweet Spot
Ndiye kodi mphamvu yokoka imawalira kuti? Ndi za zida zomwe zimafunikira kusasinthika kwamakina komanso kumalizidwa kwapamwamba kuposa kuponya mchenga, m'mavoliyumu omwe samatsimikizira kukwera mtengo kwa zida zopangira zida zothamanga kwambiri. Ganizirani mitu yamasilinda, mabulaketi omangika amlengalenga kapena magalimoto, nyumba zopopera zomwe zili zofunika kwambiri. Magawo omwe mutha kupanga makina 80% a malo, chifukwa chake mumafunikira gawo lodziwikiratu, lowundana.
Ndiwopanganso zazikulu, zolemera kwambiri. Kuthamanga kwakukulu kuli ndi malire a kukula kwake. Ndaziwona bwino kwambiri mphamvu yokoka imafa poponya ziwalo kwa makina opanga mafakitale omwe amalemera kuposa 50 kg. Inu simukuchita izo mu makina ozizira chipinda. Njirayi ndi yosinthika komanso yogwiritsira ntchito zida, ngakhale sizotsika mtengo, ndi maulamuliro amtundu wocheperako poyerekeza ndi seti yothamanga kwambiri.
Kuyang'ana mbiri ngati QSY's, yomwe imachokera kuzinthu zovuta kupanga ndalama mpaka kupanga makina, ndizomveka. Gravity die casting imalowa m'chigawo chapakati pazigawo zomwe ndizovuta kwambiri ndipo zimafunikira makina olondola. Ndi luso, osati katundu, ndondomeko. Zotsatira zake, zikachitidwa ndi mulingo wophatikizika wa kuyang'anira, si gawo chabe. Ndiwopanda kanthu wotsimikizika wopangidwa kale womwe umalola wopanga kugona usiku. Ndiko kutulutsa kwenikweni, kuposa kungodziwonetsera kwakuthupi kokha.
