1. Njira yowunikira zinthu zapulasitiki
Asanapange nkhungu, wokonzayo ayenera kusanthula bwino ndikuphunzira ngati pulasitikiyo ikugwirizana ndi mfundo yopangira jekeseni, ndipo akuyenera kukambirana mosamala ndi wopanga mankhwalawo, ndipo mgwirizano wakwaniritsidwa.Izi zikuphatikizapo zokambirana zofunika pa mawonekedwe a geometric, kulondola kwa dimensional ndi zofunikira za maonekedwe a mankhwala, ndikuyesera kupewa zovuta zosafunikira pakupanga nkhungu.
2. Mapangidwe a nkhungu
A seti apamwamba zisamere pachakudya osati amafuna zida zabwino processing ndi aluso ntchito nkhungu kupanga, komanso chinthu chofunika kwambiri ndi kukhala wabwino nkhungu kapangidwe, makamaka kwa nkhungu zovuta, khalidwe la nkhungu kapangidwe nkhani 80% ya khalidwe la nkhungu.% pamwamba.Mapangidwe abwino kwambiri a nkhungu ndi awa: pamaziko okwaniritsa zofunikira za makasitomala, mtengo wokonza ndi wotsika, zovuta zogwirira ntchito ndizochepa, ndipo nthawi yokonza ndi yochepa.
Kuti muwonjezere mawonekedwe a nkhungu, mfundo zotsatirazi ziyenera kuchitika:
1. Kumvetsetsa tsatanetsatane wa kamangidwe ka nkhungu iliyonse, ndi kumvetsetsa cholinga cha gawo lirilonse mu nkhungu.
2. Fotokozerani za mapangidwe ofanana akale popanga, ndi kumvetsetsa momwe zinthu ziliri pakukonza nkhungu ndi kupanga zinthu, ndikuphunzirapo zomwe zidachitika komanso maphunziro.
2. Phunzirani zambiri za ntchito yogwiritsira ntchito makina opangira jekeseni kuti muwonjezere mgwirizano pakati pa nkhungu ndi makina opangira jekeseni.
4. Pitani ku fakitale kuti mumvetsetse momwe zinthu zimapangidwira, ndikuzindikira mawonekedwe ndi malire amtundu uliwonse wa kukonza.
5. Mvetsetsani zotsatira za mayeso ndi kusinthidwa kwa nkhungu zomwe zidapangidwa ndi inu nokha, ndikuphunzirapo.
6. Yesani kugwiritsa ntchito bwino kwambiri nkhungu kapangidwe kake.
7. Phunzirani zambiri za chikoka cha madzi mu nkhungu pa mankhwala.
8. Phunzirani zinthu zina zapadera za nkhungu ndikumvetsetsa ukadaulo waposachedwa wa nkhungu.
3. Dziwani za nkhungu ndikusankha magawo okhazikika
Posankha zipangizo za nkhungu, kuwonjezera pa kulingalira kulondola ndi khalidwe la mankhwala, m'pofunikanso kupereka chisankho choyenera pamodzi ndi luso lenileni la kukonza fakitale ya nkhungu ndi chithandizo cha kutentha.Kuphatikiza apo, pofuna kufupikitsa nthawi yopanga zinthu, magawo omwe alipo amagwiritsidwa ntchito momwe angathere.
Chachinayi, mbali processing ndi nkhungu msonkhano
Kuwonjezera pa kupereka mapangidwe abwino kwambiri ndi kulolerana koyenera mu kapangidwe kake, kulondola kwa nkhungu ndikofunika kwambiri pakupanga magawo ndi kusonkhana kwa nkhungu.Chifukwa chake, kusankha kulondola kwa makina ndi njira yopangira makina kumakhala ndi gawo lalikulu kwambiri pakupanga nkhungu.
The dimensional zolakwika za zinthu zowumbidwa makamaka amapangidwa ndi zigawo zotsatirazi:
1. Cholakwika chopanga nkhungu ndi pafupifupi 1/3
2. Cholakwika chomwe chimabwera chifukwa cha kuwonongeka kwa nkhungu ndi pafupifupi 1/6
3. Cholakwika chomwe chimabwera chifukwa cha kuchepa kwa gawo lopangidwa ndi pafupifupi 1/3
4. Cholakwika chomwe chimabwera chifukwa cha kusagwirizana pakati pa kuchepa kwadongosolo ndi kuchepa kwenikweni kuli pafupifupi 1/6.
Chifukwa chake, kuti muchepetse cholakwika chopanga nkhungu, kulondola kwa makina kuyenera kuwongolera kaye.Pogwiritsa ntchito zida zamakina a CNC, vutoli layendetsedwa bwino.Komanso, pofuna kupewa zolakwa chifukwa nkhungu kuvala ndi mapindikidwe, quenching ayenera kugwiritsidwa ntchito zigawo zikuluzikulu monga cavities ndi mitima mu nkhungu ndi mkulu machining zofunika kulondola ndi lalikulu linanena bungwe mankhwala.
Mu nkhungu zapakatikati ndi zazikulu, pofuna kupulumutsa zipangizo ndikuthandizira kukonza ndi kutentha, mawonekedwe a mosaic ayenera kugwiritsidwa ntchito momwe angathere popanga nkhungu.
5. Njira yoyesera
Mitundu ya nkhungu ndi 70% mpaka 80% yokha yazinthu zonse zopangira kuyambira koyambira mpaka kumaliza kusonkhana.Pakuti cholakwa chifukwa cha kusagwirizana pakati shrinkage anakonzeratu ndi shrinkage kwenikweni, kaya demoulding bwino kapena ayi, mmene kuzirala zotsatira, makamaka chikoka cha kukula, udindo ndi mawonekedwe a chipata pa kulondola ndi maonekedwe a mankhwala, ayenera kuyesedwa ndi nkhungu mayesero.
Kuyesa kwa nkhungu ndi gawo lofunikira kwambiri kuti muwone ngati nkhunguyo ili yoyenera kapena ayi ndikusankha njira yabwino kwambiri yowumba.
Pambuyo pogawana, ndikukhulupirira kuti zimathandiza aliyense!
