ʻO ka paipu kila maʻemaʻe kahi ʻano o ka paipu kila kiʻekiʻe ma hope o ke kaha anu a i ʻole ka ʻōwili wela. Ma muli o ka maikaʻi o ka ʻaʻohe papa oxide ma nā paia o loko a me waho o ka paipu kila pololei, ʻaʻohe leakage ma lalo o ke kiʻekiʻe kiʻekiʻe, kiʻekiʻe kiʻekiʻe, kiʻekiʻe kiʻekiʻe, ʻaʻohe deformation i ke anu anuanu, flaring, flattening a ʻaʻohe māwae, hoʻohana nui ʻia e hana. nā huahana o nā mea pneumatic a hydraulic paha, e like me ka air cylinder a i ʻole ka ʻaila cylinder, hiki ke lilo i paipu seamless a i ʻole paipu welded.
He kiʻekiʻe ka pololei o ka paipu kila, kiʻekiʻe i loko a me waho o ka ʻili, ʻaʻohe kiʻi ʻoniʻoni ma nā ʻaoʻao o loko a me waho o ka paipu kila ma hope o ka mālama ʻana i ka wela, ʻaʻohe māwae a me ke anu anuanu deformation o ka paipu kila, hiki ke kū i ke kaomi kiʻekiʻe, a hiki ke hoʻohana no nā ʻano deformation paʻakikī a me ka hana hohonu mechanical.
Main kila paipu māka: 10#, 20#, 35#, 45#, 40Cr, 42CrMo, 16Mn, etc.
ʻO nā ʻano hana anu o ka paipu kila e komo pū me ke kaha anu a me ka ʻōwili anu. I nā makahiki i hala iho nei, me ka hoʻomohala ʻana i ka ʻepekema a me ka ʻenehana, ua hoʻomohala ʻia kahi ʻano wili anu. Hiki i kēia ʻano hana ke hoʻohua i nā paipu anu i ʻōwili ʻia a me nā ʻāpana ʻokoʻa. ʻO ka mea maka o ka paipu kila i hana ʻia e hiki ke hoʻoheheʻe ʻia i ka paipu kila ʻole a i ʻole ka paipu welded. ʻO nā hiʻohiʻona maʻamau o ke ʻano hana anuanu o ka paipu kila he kiʻekiʻe kiʻekiʻe ka pololei a me ka maikaʻi o ka ʻili. Hiki iā ia ke hana i nā paipu lahilahi lahilahi (a hiki i 0.05 ~ 0.01mm) a me nā capillaries lahilahi (a hiki i 0.3 ~ 0.1mm).
ʻO ke kiʻekiʻe kiʻekiʻe ke anu i huki ʻia me ka pololei o ka paipu kila he ʻano hou o ka paipu kila, kahi i hōʻike nui ʻia e ka pololei kiʻekiʻe. ʻElua mau kaʻina hana o ʻelua wili kiʻekiʻe a ʻekolu wili kiʻekiʻe. ʻOi aku ka kiʻekiʻe o ka pololei o ʻekolu wili kiʻekiʻe i ka hana ʻana i ka paipu kila liʻiliʻi liʻiliʻi, hiki ke hoʻomalu ʻia i loko o kekahi mau uea, akā ʻoi aku ka kiʻekiʻe o ke kumukūʻai.
ʻO ka hoʻolaha ʻana a me ka hoʻohana ʻana i ka paipu kila kiʻekiʻe i huki ʻia i ke anu hiki ke mālama i ke kila, hoʻomaikaʻi i ka hana ʻana a mālama i ka ikehu. ʻO ka mea i kapa ʻia ʻo ke anuanu kiʻekiʻe i huki ʻia i ka paipu kila maʻemaʻe ʻole e pili ana i ka pololei dimensional pololei (ʻo ke anawaena hoʻomanawanui) o loko a me waho o ke anawaena, a me ka hoʻopau ʻana i loko a me waho, ka roundness a me ka pololei, hiki ke mālama i nā hola machining, hoʻomaikaʻi i ka hoʻohana ʻana i nā mea. a hoʻomaikaʻi i ka maikaʻi o ka huahana.
ʻO ka pōmaikaʻi nui o ka paipu kila i ʻōwili ʻia ʻo ia ka nui o ka emi ʻana o ka ʻāpana, ʻoi aku ka ikaika o ka hoʻemi ʻana i ka pā. No ke kila kalapona, hiki i ka 80% ~ 83% ka emi ʻana o ka ʻāpana o ka wili hoʻokahi manawa, a ʻo ke kila kila hiki ke hiki i 72% ~ 75%. ʻO kona hemahema nui he paʻakikī ke hoʻololi i nā mea hana. Ma waho aʻe o ka hoʻohana pololei ʻia ʻana e hana i kekahi mau paipu ʻōwili anu me ka pololei kiʻekiʻe, hoʻohana pinepine ʻia ke ʻano o ka ʻōwili anu i hui pū ʻia me ke ʻano kaha kiʻi anu e wehe i nā bila no ke kiʻi anu. ʻAʻole hiki i kēia ke hāʻawi wale i ka pāʻani piha i ka hiki ke hōʻemi i ka pā o ka ʻōwili anuanu, akā hoʻohana akamai i nā pono o ka maʻalahi o ka hoʻololi ʻana i nā mea hana kiʻi anu, kahi kūpono e hoʻomaikaʻi ai i ka huahana, hoʻonui i ka laulā huahana a me ka hoʻomaikaʻi ʻana i ka maikaʻi o ka paipu kila.
I kēia manawa, hoʻokumu nui ʻia ka hana ʻana o ka paipu anu i ʻōwili ʻia ma luna o ka wili paipu anuanu. ʻO ka hiʻohiʻona hana o ka wili anu anuanu ʻaʻole e neʻe ka paipu kila a me ka mandrel. Hoʻoikaika ʻia ka wili wili e ka neʻe pānaʻi o ke kiʻi e ʻōwili i ka paipu kila i hope a i waho, a ua kaomi ʻia ka ʻāpana i ʻōwili ʻia e ka pass section variable, i mea e hoʻokō ai i ke kumu o ka hoʻemi ʻana i ke anawaena a me ka paia.
