He aha te mahi a te Pou Tiu
Ko te tiwiri me te oko he mahi takirua. Anei te raupapa ia huringa:
- Te whangai— Ka taka nga pire kirihou mai i te hopper ki te rohe whangai.
- Whakarewa— Ka puta te wera kutikuti ma te hurihuri hurihuri. Ka honoa ki nga whakamahana oko, ka rewa nga pire me te kokopi.
- Te mita- Ka rite te rewa i te pāmahana me te pehanga i mua i te werohanga.
- Werohanga— Ka anga whakamua te tīwiri ano he pupuhi, ka pana te kirihou whakarewa ki roto i te pokepokea ai.
Ko ia taurangi hoahoa - te ahuahanga, te rahinga rohe, te maimoatanga mata - ka pa ki te pai o aua kaupae e wha. Ko te kore e rite ki tetahi o enei ka kitea he raru whakaputa.
Whakatau 1: L/D Ratio
Ko te ōwehenga L/D (ko te roa o te rere o te huri kua wehea ki tona diameter) ko te tau tino nui i runga i te pepa tohu. Ka whakahaerehia e ia te wa noho, te kounga whakaranu, me te tohatoha wera.Ko te nuinga o nga tono whao werohia he 20:1.
| Resin | L/D e taunaki ana |
|---|---|
| PP, PE, PS (paerewa) | 18:1–20:1 |
| ABS, PC | 20:1–24:1 |
| PVC (wera-tairongo) | 16:1–20:1 |
| PET | 20:1–22:1 |
| Nylon (PA) | 18:1–20:1 |
| Ko nga rauemi kua whakapakarihia e te GF | 20:1–24:1 |
Whakatau 2: Tauwehenga Kōpeketanga
Ko te ōwehenga kōpeketanga (CR) ka ine te nui o te hongere tīwiri whāiti mai i te rohe whāngai ki te rohe inenga. Ko te CR teitei ake ka kaha ake te whakakoi i te rewanga - he pai mo nga kapia amorphous e ngawari haere ana. He ngawari ake te CR o raro, koinei te mea e hiahiatia ana e koe mo nga rauemi wera-wera, whakakiia ranei ki te muka.
| Resin | Tauwehenga Kōpeketanga |
|---|---|
| ABS, PC, PMMA (amorphous) | 3.0 – 3.5:1 |
| PP, PE, Nylon (hawhe-kiriata) | 2.5 – 3.0:1 |
| PVC | 2.0 – 2.5:1 |
| PET | 2.3 – 2.6:1 |
| GF-whakakaha (≥15%) | 2.0 – 2.5:1 |
Whakatau 3: Rohe Rohe
Ka wehewehea te werohanga paerewa ki nga rohe e toru. Ko te wahanga o ia rohe he mea nui ki te tapeke L/D.
- Rohe Whangai (L1):Nga hongere hohonu e whakaae ana ki nga pire totoka mai i te hopper. Roa ake = nui ake te kaha puta.
- Rohe Kōpeketanga (L2):Ka heke haere te hohonu o te hongere. Ko te nuinga o te rewa ka puta ki konei.
- Rohe Ineita (L3):Nga hongere papaku, riterite. Ka whakarite kia rite te pāmahana rewa me te pehanga i mua i te werohanga.
| Resin | Whangai (L1) | Kōpeketanga (L2) | Ineita (L3) |
|---|---|---|---|
| PP / PE | 50% | 25% | 25% |
| ABS / PC | 40% | 40% | 20% |
| PET | 40% | 40% | 20% |
| Nylon (PA) | 35–45% | 35–40% | 20–25% |
| PVC | 35% | 50% | 15% |
Whakatau 4: Rauemi Pae Tiu
38CrMoALA — Te Paerewa Paerewa
He mea hanga mai i a Nanhaiya te werohanga mo te hanga38CrMoALA koranu maitai, whakamahana wera me te tineia. Ko tenei rauemi turanga e mau ana i nga thermoplastics paerewa penei i te PE, PP, PS, me te ABS pai, me te roa o te oranga ratonga10,000–20,000 haorai raro i nga tikanga whakahaere noa.
Te whakangao
Ko te hau nitriding i te 500–560°C ka hanga he paparanga nitrided0.5–0.8mm te matotorume te pakeke o950–1050 HV (~62 HRC). Ma tenei ka pai ake te aukati kakahu ma te 30-40% ka whakatauritea ki te rino kaore i mahia. Paerewa mo te nuinga o nga tono whakakikorua i werohia e whakahaere ana i nga rawa kaore i whakakiia, ngawari ranei te whakakii.
Nanhaiya mutant (pohopu) werohia te wiri - e tika ana mo nga kapia tioata penei i te PP, PE, me te Nylon.
Bimetallic — Mo nga tono abrasive
Ko nga paera Bimetallic he ararewa whakakakahu-atete teitei e honoa ana ki te kohao oko. Ko te tukanga bimetallic a Nanhaiya ka tutuki hete pakeke o roto o te 62 HRCna roto i te rehu rehu koranu uaua huri noa i nga waahi kakahu teitei o roto o te oko.
| Taupānga | Rauemi Tiu | Mahinga Paera |
|---|---|---|
| PE, PP, PS (kaore i whakaki) | 38CrMoALA nitrided | Paerewa nitrided |
| ABS, PC, Nylon (kaore i whakaki) | 38CrMoALA nitrided | Paerewa nitrided |
| PA + GF ≤30% | 38CrMoALA, kua tineia + kua weriweri | Nitrided, bimetallic ranei |
| ihirangi GF 15–50% | Bimetallic / TC tapa rererangi | Bimetallic |
| PVC / kapia waikura | Koranu waikura-ātete | Bimetallic (CR māka) |
| Ka whakakiia te muka waro | Tungsten carbide | Poka rehu TC |
Te Whakatau 5: Te Taaawa o te Tiu me te Rahi Pu
Me taka to pere tūturu ki waenganui35% me te 70%o te kaha o te pupuhi morahi o te tira. Kei raro iho i te 35%, he roa rawa te noho o te taonga ki roto i te oko, ka tupono te paheketanga. I runga ake i te 70%, kare e taea e te tiwiri te whakaora tere i roto i te huringa.
Kei raro nei nga whirihoranga noa mai i Nanhaiya:
| Rahi Wero (g) | Tiu Ø × Roa (mm) | Pae Ø × Roa (mm) |
|---|---|---|
| 30–90 | Φ30×900 | Φ85×860 |
| 60–125 | Φ35×910 | Φ85×860 |
| 100–150 | Φ38×935 | Φ95×900 |
| 125–300 | Φ42×1030 | Φ105×1110 |
| 250–400 | Φ45×1210 | Φ115×1165 |
| 300–500 | Φ50×1300 | Φ125×1260 |
| 500–700 | Φ60×1380 | Φ140×1350 |
| 700–1000 | Φ70×1790 | Φ160×1685 |
| 1000–1500 | Φ160×3500 | Φ270×3200 |
| 1300–2500 | Φ170×3415 | Φ317×3380 |
Nanhaiya i werohia te huri - pai ake mo nga kapia amorphous penei i te ABS, PC, me te PMMA.
