Waa maxay Foostada Screw ee Dhabta ah
Furka iyo foostadu waxay u shaqeeyaan sidii lammaane is-bar-bar socda. Waa kan isku xigxiga meerto kasta:
- Quudinta- Pellets balaastikada ah ayaa ka soo daada hopper waxayna galaan aagga quudinta.
- dhalaalay- Furaha wareega ayaa dhaliya kulaylka xiirta. Marka lagu daro kuleyliyeyaasha foosto, pellets ayaa dhalaali oo cadaadiya.
- Qiyaasta- dhalaalashadu waxay noqotaa mid isku mid ah heerkulka iyo cadaadiska ka hor duritaanka.
- Duritaan- Karoolku hore ayuu u socdaa sida tuubada oo kale, isaga oo ku riixaya baco dhalaalay caaryada.
Doorsoome kasta oo nashqad leh - joomatari, saamiga aagga, daawaynta dusha - waxay saamaysaa sida wanaagsan ee afartaas tallaabo u dhacaan. Isku-dheeli la'aanta mid kasta oo iyaga ka mid ah waxay u muuqataa dhibaato wax soo saar.
Go'aanka 1: L/D Saamiga
Saamiga L/D (dhererka duulaya ee loo qaybiyay dhexroorkiisa) waa lambarka ugu muhiimsan xaashida gaarka ah. Waxay maamushaa wakhtiga deganaanshaha, tayada isku dhafka, iyo qaybinta kulaylka.Inta badan codsiyada qaabaynta duritaanka guud waxay isticmaalaan 20:1.
| Resin | Lagu taliyay L/D |
|---|---|
| PP, PE, PS (standard) | 18:1 – 20:1 |
| ABS, PC | 20:1 – 24:1 |
| PVC (kuleelka xasaasiga ah) | 16:1 – 20:1 |
| PET | 20:1 – 22:1 |
| Naylon (PA) | 18:1 – 20:1 |
| Agabka lagu xoojiyay GF | 20:1 – 24:1 |
Go'aanka 2: Cabbirka Saamiga
Saamiga isku-buufinta (CR) wuxuu cabbiraa inta uu kanaalka daboolku ka soo cidhiidhinayo aagga quudinta ilaa aagga cabbirka. CR-ga sare wuxuu si xoog leh u cadaadiya dhalaalka - wuxuu u fiican yahay xabagta amorphous ee si tartiib tartiib ah u jilcisa. CR-da hoose waa ka khafiifsan tahay, taas oo ah waxa aad u baahan tahay kulayl-xasaasi ah ama walxo ka buuxa fiber-ka.
| Resin | Saamiga cadaadis |
|---|---|
| ABS, PC, PMMA (amorphous) | 3.0 – 3.5:1 |
| PP, PE, Naylon (semi-crystalline) | 2.5 – 3.0:1 |
| PVC | 2.0 – 2.5:1 |
| PET | 2.3 – 2.6:1 |
| GF-xoojiyey (≥15%) | 2.0 – 2.5:1 |
Go'aanka 3: Saamiga Aagga
Cirbadda cirbadeynta caadiga ah waxay u qaybsantaa saddex aag. Saamiga aag kasta ayaa muhiimad gaar ah u leh wadarta guud ee L/D.
- Aagga Quudinta (L1):Kanaallo qoto dheer oo aqbala pellets adag ka soo hopper. Ka dheer = awood wax soo saar badan.
- Aagga Cadaadiska (L2):Qoto dheer ee kanaalka ayaa si tartiib tartiib ah hoos ugu dhacaya. Inta badan dhalaalashadu waxay ku dhacdaa halkan.
- Aagga Qiyaasta (L3):Shall, channels joogto ah. Waxay xaqiijisaa heerkulka dhalaalka iyo cadaadiska isku midka ah ka hor duritaanka.
| Resin | Quudinta (L1) | Cadaadiska (L2) | Qiyaasta (L3) |
|---|---|---|---|
| PP/PE | 50% | 25% | 25% |
| ABS / PC | 40% | 40% | 20% |
| PET | 40% | 40% | 20% |
| Naylon (PA) | 35-45% | 35-40% | 20-25% |
| PVC | 35% | 50% | 15% |
Go'aanka 4: Qalab Foosto ah
38CrMoALA - Heerka Saldhigga
Muraayado qaabaynta duritaanka Nanhaiya ayaa laga soo saaray38CrMoALA aluminium bir ah, kuleyl lagu daaweeyay oo la demiyay. Maaddadan saldhigga ahi waxay si fiican u qabataa heerkulbeegyada caadiga ah sida PE, PP, PS, iyo ABS, oo leh nolol adeeg ku dhawaad10,000-20,000 saacadoodxaaladaha shaqada ee caadiga ah.
Nitriding
Nitriding gaaska 500-560°C waxay samaysaa lakab nitrided ah0.5-0.8mm qaro weynoo adag oo ah950-1050 HV (~ 62 HRC). Tani waxay hagaajinaysaa caabbinta xidhashada 30-40% marka la barbar dhigo birta aan la daweyn. Halbeegga badi codsiyada qaabaynta duritaanka ee ku socda alaab aan la buuxin ama si fudud loo buuxin.
Naanhaiya mutant (kadis ah) iskudubaynta qaabaynta - ku habboon resins crystalline sida PP, PE, iyo nylon.
Bimetallic - Loogu talagalay Codsiyada Abrasive
Fuustooyinka bimetallic waxay leeyihiin dahaar heersare ah oo u adkaysta dahaarka birta oo ku xidhan foostada. Habka bimetallic ee Nanhaiya wuxuu gaaraa aadkaanta gudaha gudaha ee 62 HRCiyada oo loo marayo alxanka buufinta daawaha adag ee agagaarka aagagga dharka sare ee gudaha foostada.
| Codsiga | Qalab qallafsan | Daaweynta Foosto |
|---|---|---|
| PE, PP, PS (aan buuxin) | 38CrMoALA nitrided | Heerka nitrided |
| ABS, PC, nylon (aan buuxin) | 38CrMoALA nitrided | Heerka nitrided |
| PA + GF ≤30% | 38CrMoALA, demisay + xanaaqsan | Nitrided ama bimetallic |
| Waxa ku jira GF 15-50% | Cidhifyada duulimaadka Bimetallic / TC | Bimetallic |
| PVC / resins daxalka ah | Daawaha u adkaysta daxalka | Bimetallic (darajada CR) |
| Kaarboon fiber ka buuxsamay | Tungsten carbide | Dhalada TC-buufin |
Go'aanka 5: Dhexroorka dhexroorka iyo cabbirka xabbadda
Tallaalkaada dhabta ahi waa inay u dhexeeyaan35% iyo 70%ee awoodda ugu badan ee boolal. In ka hooseeya 35%, alaabtu waxay ku fadhidaa foosto aad u dheer waxayna halis u tahay hoos u dhac. In ka badan 70%, furku si degdeg ah uguma soo kaban karo wareegga dhexdiisa.
Hoos waxaa ah qaabaynta guud ee laga heli karo Nanhaiya:
| Qadarka duritaanka (g) | Dabool Ø × Dhererka (mm) | Foosto Ø × Dhererka (mm) |
|---|---|---|
| 30–90 | Φ30×900 | Φ85×860 |
| 60-125 | Φ35×910 | Φ85×860 |
| 100-150 | Φ38×935 | Φ95×900 |

| 700-1000 | Φ70×1790 | Φ160×1685 |
| 1000-1500 | Φ160×3500 | Φ270×3200 |
| 1300-2500 | Φ170×3415 | Φ317×3380 |
Muraayada duritaanka tartiib tartiib ah ee Nanhaiya - waxay u roon tahay xabagta amorphous sida ABS, PC, iyo PMMA.
Calaamadaha Digniinta ee Kaalmadaada Hadda Kugu Qaldan Shaqada
- Dhibco madow ama calaamado gubasho- Walxaha wax u dhimaya wakhtiga degenaanshaha xad dhaafka ah ama meel kulul. Hubi aagagga heerkulka foostada oo nadiifinta furka.
- Miisaanka toogtay ee aan iswaafaqayn- Inta badan waalka aan soo laabanayn ee xidhan ama foosto xad-dhaaf ah oo ka leexiya foosto taas oo ogolaanaysa dib u socodka.
- Calaamadaha ku dhufashada dusha sare- Qoyaanka ama gaaska dhalaalka. Waxa laga yaabaa inay muujiso qalajin aan ku filnayn ama joomatari bir ah oo aan si fiican u soo bixin.
- Soo kabashada gaabis ah / wakhti wareeg dheer- Awoodda balaastiga kuma filna. Dhexroorka qulqulka waxay u badan tahay inuu u baahan yahay inuu kordhiyo.
- Dusha sare ee isbeddelka midabka- Isku-dhafka liita ee aagga cabbirka. Maddock ama curiyaha isku darka xannibaadda ee lagu daray furka ayaa inta badan xalliya tan.
