Njira yopanga nkhungu

(一) Njira yopanga nkhungu

1, The mapulogalamu kapangidwe 2, The nc Machining 3, Post processing 4, Mayeso kupambana 5, Pamanja nkhungu kapangidwe 6, Katswiri kukopera nambala 7, The nkhungu mawonekedwe 8, nkhungu zambiri 9, Ikani mu ntchito 10, Yaiwisi kusankha 11, Zitsulo , kufa opanda kanthu

(二) Tanthauzo lazonse zankhungu

Pakupanga mafakitale, ndi makina osindikizira osiyanasiyana ndi zida zapadera zomwe zimayikidwa pa makina osindikizira, kupyolera mu kukakamizidwa kuti apange zitsulo kapena zinthu zopanda zitsulo mu mawonekedwe ofunikira a ziwalo kapena zinthu, chida chapadera ichi chimadziwika kuti ndinkhungu.
Kuchuluka kwa ntchito: makina, magalimoto, mafakitale opepuka, zida zapakhomo, mafuta, mankhwala, mphamvu yamagetsi ndi zida zina zamafakitale zopangira ndikugwiritsa ntchito madipatimenti, zida zogwirira ntchito zamakina oyendetsa ndege, magawo otentha a extrusion kufa, filimu yotentha ya extrusion, kukhudza kotentha, kugudubuza zitsulo. kalozera, gudumu lozungulira, camshaft ya injini yamagalimoto ndi magawo ena ndikumwalira.

(三) Gulu la nkhungu

1. General classification: ikhoza kugawidwa mu nkhungu ya pulasitiki komanso yopanda pulasitikinkhungu:

(1) nonpulasitiki nkhungu: kuponyera nkhungu, kuumba nkhungu, kupondaponda kufa, kufa kuponyera nkhungu, etc. Noun Malangizo:

Kupanga kumakhala kolimba - pambuyo potenthetsa kapena kulimba - kupangakuumba;Kuponya kumakhala kolimba - kutenthedwa kukhala madzi - kuponyedwa - kokhazikika kuti apange.

A. The Casting Mold ikhoza kupangidwa ndi matabwa, machinable pulasitiki, aluminiyamu aloyi, chitsulo chosungunuka, chitsulo ndi zina zotero.Pakalipano, nkhungu zamatabwa zimagwiritsidwabe ntchito kwambiri popanga mapepala kapena kupanga batch kakang'ono ka chidutswa chimodzi, koma ndi kuchepetsa zofunikira za chitetezo cha chilengedwe ndi ntchito yokonza matabwa, kuponyera nkhungu kolimba kudzatenga malo ake.Kuponyedwa kwa nkhungu kolimba kumapangidwa ndi mapepala apulasitiki a thovu, odulidwa ndi kuikidwa mu mawonekedwe, kenako kuponyedwa.Poyerekeza ndi matabwankhungu, njira imeneyi ndi yochepa mkombero ndi mtengo wotsika.

B. Kupanga nkhungu - thupi lagalimoto (zoposa 20,000 zimafunikira pa nkhungu imodzi yagalimoto)

C. Stamping Mold - gulu la makompyuta

(2) Malinga ndi kupanga ndi kupanga zinthu zosiyanasiyana, nkhungu ya pulasitiki imagawidwa kukhala:

Otchedwa pulasitiki jekeseni nkhungu, ndi pasadakhale zidutswa ziwiri kapena kuposa nkhungu wapadera zitsulo pamwamba pofukula patsekeke chopanda kanthu.Kenako, chifukwa cha kuthamanga kwambiri, tinthu tating'ono ta pulasitiki tosungunuka timalowetsedwa m'bowo, ndipo nkhungu zazinthu zapulasitiki zimachotsedwa pambuyo pozizirira.Pakadali pano, zopitilira 90% zazinthu zamapulasitiki m'moyo wathu watsiku ndi tsiku zimapangidwa ndi jekeseni.

Chiyembekezo cha msika?Kuchuluka kwakukulu, kugwiritsa ntchito kwakukulu, kodzaza kale.

Chiyembekezo cha msika?Kuchuluka kwakukulu, kugwiritsa ntchito kwakukulu, kodzaza kale.

Kumangira jekeseni ndi njira yomwe imagwiritsidwa ntchito kwambiri pokonza pulasitiki.Njira imeneyi ndi ntchito kwa onse thermoplastics ndi mbali ya thermosetting mapulasitiki, mankhwala pulasitiki anapanga chiwerengero chachikulu cha iwo ndi njira zina kupanga fumbi, monga chida chachikulu cha jekeseni akamaumba processing, mmodzi wa nkhungu jekeseni, khalidwe mwatsatanetsatane, kupanga. mkombero ndi jekeseni akamaumba kupanga dzuwa mu ndondomeko ya mlingo wa mkulu ndi otsika, mwachindunji zimakhudza khalidwe mankhwala, zokolola, mtengo ndi zosintha mankhwala, pa nthawi yomweyo chimatsimikizira ogwira ntchito mu msika mpikisano luso ndi liwiro anachita.

Jekeseni nkhungu imapangidwa ndi mbale zingapo zachitsulo zomwe zili ndi magawo osiyanasiyana, zomwe zimagawidwa kukhala: Chipangizo chopangira (concave die, punch)

B. Chida choyikira (chithunzi chowongolera, manja owongolera)C.Kukonzekera (I-plate, code pit)D.Dongosolo lozizira (dzenje lamadzi)

E Constant kutentha dongosolo (kuwotcha chubu, tsitsi)

F Runner System (bowo lothamanga, poyambira, dzenje lothamanga)

G ejector system (thimble, ejector)

Njira yopangira jakisoni: Jekeseni nkhungu ndi chida chopangira zinthu zapulasitiki.Amakhala ndi zigawo zingapo zomwe nkhungu imapangidwira.Pamene jekeseni akamaumba, nkhungu ndi clamped mu makina jekeseni akamaumba, pulasitiki wosungunula jekeseni mu nkhungu patsekeke, ndipo kuzirala mu patsekeke anamaliza, ndiyeno zisamere pachakudya chapamwamba ndi m'munsi zisamere nkhungu analekanitsidwa, kudzera ejecting dongosolo adzakhala mankhwala. kuchokera ku nkhungu kuchokera mu nkhungu, ndipo potsirizankhunguchatsekedwa lotsatira jekeseni akamaumba, lonse jekeseni akamaumba ndondomeko ikuchitika mkombero.

Chithuza nkhungu: Kupanga matuza nkhungu, mtengo wotsika kwambiri ndi nkhungu gypsum, kutsatiridwa ndi electroplating mkuwa nkhungu, okwera mtengo kwambiri ndi aluminium nkhungu.Chikombolecho chimabowoleredwa ndi mabowo ang'onoang'ono kuti adsorption ya zidutswa zolimba za thermalized kuti apange pulasitiki.
