ʻO nā pahi ʻokiʻoki mahiʻai, paʻa a kūpaʻa i ke komo ʻana
Nā diski ʻoki ʻoki ʻia: Loaʻa i ka lihi o waho o ka diski nā ʻoki ʻano arc a i ʻole trapezoidal, e ʻae ana i ka komo wikiwiki ʻana o ka lepo a me ke kū'ē haʻahaʻa. He akamai lākou i ka ʻoki ʻana i ka ʻōpala lōʻihi, ka ʻōpala kulina, a me nā nāhelehele i hiʻipiʻi ʻia, e kūpono ai no ka mahi mua ʻana i nā lepo lepo kaumaha a i ʻole nā mahina me ka ʻōpala kiʻekiʻe.
Nā ʻāpana ʻōpala poepoe a laumania: He laumania a hoʻomau nā ʻaoʻao, e hopena ana i kahi pālahalaha kiʻekiʻe o ka ʻili a me ka haki like ʻana o ka lepo ma hope o ka mahi ʻana. He kūpono lākou no ka lepo one māmā, ka haki lua o ka lepo ma hope o ka mahi ʻana, a me ka hoʻomākaukau ʻana i ka moena hua ma mua o ka lūlū ʻana.
Hoʻohana kēia moʻo o nā pahi rake i ke kila manganese 65Mn a i ʻole ke kila boron kiʻekiʻe 30MnB ma ke ʻano he mea kumu. Loaʻa i nā mea ʻelua ka palena elastic maikaʻi loa a me ka paʻakikī hopena. Ma hope o ke kāwili ʻana i ka mahana kiʻekiʻe, hana ʻia ka pahi holoʻokoʻa i ka quenching isothermal a i ʻole ka mālama wela ʻāpana, e hoʻokō ana i ka paʻakikī hope loa o 38-48 HRC me ka mālama ʻana i ka maʻalahi o ke kumu. Hoʻoponopono kēia i ka kūʻē ma waena o "ka paʻakikī kiʻekiʻe e alakaʻi ana i ka chipping a me ka paʻakikī kiʻekiʻe e alakaʻi ana i ka chipping." Hiki ke hoʻopili ʻia ka ʻaoʻao ʻokiʻoki i ka carburized surface a i ʻole ka laser paʻakikī, e hoʻonui hou ana i ka paʻakikī i luna o 56 HRC a hoʻomaikaʻi i ke ola ʻaʻahu ma mua o 30%.
ʻO nā pahi rake corrugated: me nā ʻaoʻao nalu, hoʻohana nui ʻia no ka wehe ʻana i ka papa ʻili ma hope o ka uhi ʻana i ka hua a me ka hoʻopili ʻana. He pāpaʻu ka hana akā maikaʻi ka hopena uhi. Hoʻohana pinepine ʻia lākou me nā mea lūlū hua.
Hoʻokumu ʻia kēlā me kēia pahi rake e ka milo CNC a i ʻole ka forging pololei e hōʻoia i ka holo ʻana o ke anawaena o waho o ≤1.5mm, e hopena ana i ka wili mālie a ʻaʻole e wili ma hope o ka ʻākoakoa ʻana. Ua hou ʻia ka lua hoʻopaʻa waena me ka pololei, me nā ʻae ʻana o ke anawaena i kāohi pono ʻia i loko o ka papa H9, e hōʻoia ana i kahi kūpono paʻa me ke koʻokoʻo rake. Ma mua o ka haʻalele ʻana i ka hale hana, 100% o nā huahana e hele i ka nānā ʻana i nā ʻāpana magnetic ʻike maka a me nā hoʻāʻo laʻana paʻakikī e hoʻopau i nā microcracks a i ʻole nā kiko palupalu.
Hoʻohana nui ʻia no ka wehe ʻana i ka ʻōpala a me ka wehe ʻana i ka lepo ma nā mahina ʻai kulina maloʻo, palaoa, a me ka soybean; a me ke kanu ʻana i ka mauʻu a me ka pulping ma nā mahina ʻai paddy hoʻoilo. Hiki ke hoʻohālikelike ʻia me nā set harrow disc mai nā lama kūloko a me nā lama honua (e like me Reken, Kuhn, Deere, etc.), a hiki ke hoʻopilikino ʻia e like me nā kiʻi a ka mea kūʻai aku me nā diameters like ʻole (450-700mm), nā mānoanoa (4-8mm), a me nā kikoʻī o ka lua waena.
