ʻO ka hōʻuluʻulu o nā ʻano hana ʻewalu o ka milo, pono ʻoe e ʻike i ka hana ʻana i ka mīkini

ʻO ka ʻāpana ʻelua: ʻO ka ʻōwili ʻana i ke kaula
ʻO ke ʻano hana o ka plastically deforming i ka mea hana me ka make rolling forming e loaʻa ai kahi kaula. Hana ʻia ka ʻōwili kaula ma ka mīkini ʻōwili a i ʻole ka lathe ʻakomi me ka wehe ʻana a me ka pani ʻana o ke poʻo ʻōwili kaula, kahi milo waho no ka hana nui ʻana i nā mea hoʻopaʻa maʻamau, a me nā mea hoʻohui ʻē aʻe. ʻO ke anawaena o waho o ka Thread i ʻōwili ʻia ʻaʻole i ʻoi aku ma mua o 25 mm, ʻaʻole i ʻoi aku ka lōʻihi ma mua o 100 mm, hiki i ka pololei o ke kaula ke piʻi i ka pae 2 (GB197-63), a ʻo ke anawaena o ka blank i hoʻohana ʻia e like me ke anawaena pitch. o ka Thread i hanaia. ʻAʻole hiki i ka RThread ke hoʻoponopono i nā loina o loko, akā no nā mea hana me nā mea palupalu, hiki ke hoʻohana ʻia kahi kīʻaha extrusion ʻaʻole i hoʻohana ʻia e hoʻokuʻu i nā kaula kūloko (hiki ke anawaena kiʻekiʻe ma kahi o 30 mm). ʻO ke kumu hana e like me ka paʻi ʻana. ʻO ka torque i koi ʻia no ka hoʻokuʻu ʻia ʻana o nā kaula i loko ma kahi o 1 mau manawa ʻoi aku ka nui o ka paʻi ʻana, a ʻoi aku ka kiʻekiʻe o ka pololei o ka mīkini a me ka maikaʻi o ka ʻili ma mua o ka paʻi ʻana.

Nā pōmaikaʻi o ka ʻōwili ʻana i ka Thread:

① ʻOi aku ka liʻiliʻi o ka ʻili ma mua o ka huli ʻana, ka wili, a me ka wili;

② Hiki i ka ʻili o ka Thread afThreadlling ke hoʻomaikaʻi i ka ikaika a me ka paʻakikī ma muli o ka paʻakikī o ka hana anu;

③Ke kiʻekiʻe ka nui o ka hoʻohana ʻana i nā mea;

④Hoʻonui pālua ʻia ka huahana i ka ʻoki ʻana, a maʻalahi ke ʻike i ka automation;

⑤ He lōʻihi loa ke ola o ka mea ʻōwili. Eia naʻe, ʻaʻole ʻoi aku ka paʻakikī o ka mea hana ma mua o HRC40; ʻoi aku ka kiʻekiʻe o ka kikoʻī o ka blank; ʻO ka pololei a me ka paʻakikī o ka'ōwili die he kiʻekiʻe hoʻi, a he paʻakikī ke hana i ka make; ʻAʻole kūpono ia no ka ʻōwili ʻana i nā kaula me ke ʻano niho asymmetric.
E like me ka make ʻana o ka ʻōwili like ʻole, hiki ke hoʻokaʻawale ʻia ka Thread i ʻelua ʻano: Thread rolling a me Threadthreadd

6. Olokaʻi ʻia ka milo

Hoʻonohonoho ʻia ʻelua mau papa ʻōwili me nā ʻano niho wili ʻia e kū pono ana kekahi i kekahi me ka pitch 1/2; paʻa ka pā paʻa, a neʻe ka pā neʻe i kahi neʻe laina pānaʻi e like me ka pā paʻa. Ke hoʻouna ʻia ka mea hana ma waena o nā papa ʻelua, neʻe ka pā neʻe i mua a hamo i ka mea hana e hoʻololi i ka ʻili i mea e hana ai i kaula (Figure 6 [Screwing]).

7. Olokaʻi ʻia ka milo

ʻEkolu ʻano o ka radial Thread roThread, tangential Thread roThread, a me ka rolling head thread rolling.
①Radial Threathreadad 2 (a i ʻole 3) nā huila ʻōwili me nā ʻaoʻao pili i hoʻokomo ʻia ma nā kumu like ʻole; kau ʻia ka mea hana ma ke kākoʻo ma waena o nā huila ʻelua, a ʻo nā huila ʻelua e hoʻohuli i ka ʻaoʻao hoʻokahi a me ka wikiwiki like (Figure 7). [Ke holo nei ʻo Radial Thread]), kekahi o nā pōʻai, hana pū i ka neʻe ʻana o ka hānai radial. Hoʻololi ka huila wili i ka mea hana, a hoʻokuʻu ʻia ka ʻili e hana i nā kaula. No kekahi mau wili kepau i koi ʻole i ka pololei kiʻekiʻe, hiki ke hoʻohana ʻia ke ʻano like no ka hana ʻōwili.
②Tangential Thread roThread Ua kapa ʻia hoʻi he planetary Thread roThread. Hiki ke hānai mau ʻia ka mea hana i ka wā Thread thread, no laila ʻoi aku ka kiʻekiʻe o ka huahana ma mua o ka Thread roThreadand radial Thread thread
③ Hoʻopaʻa hou ʻia ke kaula: Hana ʻia ia ma ka lathe maʻamau a hoʻohana mau ʻia e hana i nā lola pōkole ma ka mea hana. Aia he 3 a 4 mau huila wiliwili i puunaue like ia ma ka aoao o waho o ka mea hana ma ke poo olokaa (Fig. 9 [Kaawili hou ana i ke kaula]). I ka wā o ka ʻōwili ʻana o ka milo, kaʻa ka mea hana, a hānai ʻia ke poʻo ʻōwili axially e ʻōwili i ka mea hana ma waho o ka Uila.

Hoʻopaʻa kaula

ʻO ka hana ʻana o nā milo maʻamau e hoʻohana maʻamau i nā kikowaena mīkini a i ʻole ka paʻi ʻana i nā mea hana a me nā mea hana; i kekahi manawa, hiki no hoi ke pai lima. Eia nō naʻe, i kekahi mau hihia koʻikoʻi, ʻaʻole maʻalahi ke ala ma luna e loaʻa ai nā hopena hoʻoponopono maikaʻi, e like me ka pono o ka mīkini mīkini ma hope o ka mālama ʻana i ka wela o nā ʻāpana ma muli o ka mālama ʻole ʻana a i ʻole nā ​​​​mea paʻa, e like me ka pono e paʻi pololei i nā mea hana carbide. . I kēia manawa, pono e noʻonoʻo i ke ʻano hana pEDM.
Ke hoʻohālikelikeʻia me keʻano machining,ʻo ke kaʻina hana EDM ma keʻano hoʻokahi: pono e wili muaʻia ka lua lalo, a pono e hoʻoholo i ke anawaena o ka lua lalo e like me nā kūlana hana. Pono e hoʻopili ʻia ka electrode i kahi ʻano milo, a pono e hiki i ka electrode ke hoʻololi i ka wā o ka mīkini.
