Te whakamahinga taipitopito o te huānga miro o te extruder kirihou tīwiri rua whakarara

Ngā āhuatanga o te extruder tīwiri takirua kirihou whakarara:
1. Te tere tere me te tere nekehanga tata i ngā tūranga rerekē o te rohe hononga (ka taupatupatu ngā tīwiri e rua i roto i te hoahoa whakawhiti-wāhanga), kia taea ai te whakaputa i te kutikuti kaha me te ōrite;
2. E kī ana te āhuahanga me tuwhera ngā arai roa kia taea ai te whakawhiti rauemi i waenga i ngā tīwiri e rua. I te wā o te whakawhiti, ka neke te rauemi i te raro o tētahi awaawa tīwiri ki te tihi o tētahi atu awaawa tīwiri. Mā te whakatuwheratanga o ngā awaawa roa ka taea hoki te whakatuwheratanga o ngā awaawa whakawhiti hei whakawhiti rauemi i waenga i ngā mokowā tata o te tīwiri kotahi. Mā tēnei ka pai ake te tohatoha me te kaha whakaranu o ngā kirihou o te mīhini whakaputa tīwiri takirua e hurihuri tahi ana.
Mena he kōrero mō ngā rauemi mai i te tīmatanga o temīhini whakaputa tīwiri kirihouki te pito o te tīwiri, te wāhi e taea ai e te rauemi te rere mai i tētahi tīwiri ki tētahi atu (arā, he rere kei te taha o te mokowā tīwiri), ka kiia tēnei he whakatuwheratanga roa, ki te kore ka kiia he katinga roa. I te rohe hononga o ngā tīwiri e rua, ki te mea he ara kei te tīwiri, arā, ka taea e te rauemi te rere mai i tētahi atu mokowā o taua tīwiri anō, ka taea rānei e te rauemi mai i tētahi mokowā o tētahi tīwiri te rere ki ngā mokowā e rua e tata ana o tētahi atu tīwiri, ka kiia he whakatuwheratanga whakawhiti, ki te kore ka kiia he katinga whakawhiti.
E tuwhera poutū ana ngā wāhanga kawe, e kati whakapae ana; e tuwhera poutū ana, e tuwhera whakapae ana hoki ngā poraka hononga.

1. Ngā huānga tuku

E toru ngā āhuatanga matua o te huānga kawe: te ahunga kawe, te teitei me te maha o ngā pane miro.
1) Te aronga tuku
Tukunga whakamua: ka neke te rauemi ki te pito o te taputapu
Tukunga whakamuri: ka neke atu te rauemi i te pito tukunga o te taputapu.
2) Te papa tākaro
Tawhiti: hurihia te roa tuaka hurihuri o te mata
Ka taea e te piko te whakatau i te rauemi, te tere, te puhoi rānei hei whakahaere i te taumata whakakī. Ka taea te whakamahi i te huānga kawe whakamuri hei rauemi huānga "whakawhāiti" i roto i te tīwiri.
▲ Ngā āhuatanga o te papa nui (i waenga i te 1.5 me te 2 ngā wā whānui): te kaha mōrahi; te tere tuku tere rawa; te whakakī iti rawa; mō te whāngai me te whakaputanga hau.
▲ Ngā āhuatanga o te papa waenga (1 x diameter): te kaha waenga; te tere tuku waenga; te pikinga o te whakakī i ngā wāhanga papa nui o raro.
▲ Te papa iti (0.25 ki te 0.75 x te whānui): te iti rawa o te kaha; te puhoi rawa o te tuku; te whakanui ake i te whakakī i te wāhanga papa reo o raro; te whakakī mōrahi me te kore pēhanga i muri; te kaha o te horapa wera me te papu.
3) Te maha o ngā pane miro

▲ Ngā āhuatanga o te huānga upoko kotahi: ka taea e te mata whānui te whakaiti i te turuturu rauemi; he iti ake i te kaha o te tīwiri upoko rua; he tino pai te tango.
▲ Ngā āhuatanga o ngā huānga e rua: ngā wāhanga paerewa o te huānga kawe tīwiri takirua kotahi; he iti ake te kaha kutikuti i ngā huānga e toru; mō te whāngai totoka, te tuku rewa, te putanga hau me te papu rewa.
▲ Ngā āhuatanga o te huānga upoko-toru: te kaha kutikuti mōrahi; te hohonu o te awaawa papaku; mō te whakarewa, te whakaranu marara.
4). Huānga whakamuri
Ngā Āhuatanga: 100% whakakī ki mua; mō te hiri rewa (korehau), he nui te kaha kutikuti e whakaurua ana.
5). te huānga SK
Ngā Āhuatanga: whakanui i te kaha; whakanui i te kaha tuku; e whakamahia ana mō te whāngai (ehara i te horoi-ake)

2. Poraka kiore

★ Te whakaranu tohatoha me te whakaranu marara
▲ Te whakaranu tohatoha
Ko te whakaranu tohatoha te tukanga e whakaōrite ana i te rauemi, ā, kāore e whakarerekē i te rahi o te rauemi, engari ko te tūranga ōrite anake e whakarerekē ana.
Mā te whakaranu tohatoha ka wehewehea te rewa me te whakakotahitanga, ā, ka ōrite te tohatoha ā-wāhi o ia wāhanga. Ko te nuinga o tēnei ka whakatutukihia mā te nekehanga rere i raro i ngā taumahatanga pēnei i te wehenga, te totoro (ka puta i waenga i te pēhanga me te whakawhānui), te whakapōturi, me te hurihanga o te mahi wai.
▲ Ranunga motuhake

Mā te ranunga marara ka pakaru ngā huānga ki ngā matūriki, ka kawea rānei ngā wāhanga e rua kāore e hototahi ki te awhe e hiahiatia ana, ko te nuinga o tēnei ka tutuki mā te pēhanga kutikuti me te ahotea toronga. Hei whakatutuki i te mea e kiia nei ko te ranunga kuru "pai", ka mahi tahi te ranunga kuru me te ranunga tohatoha.
Ka whakaritea ngā wahi taumau kia maeneene, kia whakamuri rānei i ētahi koki (30°, 45°, 60°, 90° rānei). I ngā pane e rua, ko te maha o ngā mata hei neke i te mata mā te 180°, KB 30° = 7, KB 45° = 5, me KB 60° = 4.
Ka taea te wehewehe i te ahunga kawe o te poraka hononga ki mua, ki muri, me te kore e piko. Mēnā he rite te koki o te poraka mata, ka rerekē ngā pānga o te matotoru o te mata, ki te whakatauritea ki te pikitia i raro nei:

▲ Poraka hononga KB 30°
Tērā pea ka taea te whakaranu i te āputa i waenga i ngā rau mata; he iti te āputa i waenga i ngā awa; whakamua = iti te whakaranu; whakamuri = teitei te pēhanga
▲ Poraka hononga KB 45°
He nui ake te kaha whakaranu i te mata 30°; he iti iho i te mata 30°; whakamua = ranunga kaha reo; whakamuri = pēhanga reo ki te nui
▲ Poraka hononga KB 60°
He kaha ake te kaha whakaranu i te 45°; he iti ake te kaha tuku i te 45°; whakamua = whakaranu taurite; whakamuri = pēhanga taurite ki te iti
▲ Poraka hononga KB 90°
Kāore e taea te whakawhiti; 100% whakakī (pēhanga iti); ranunga kaha
