He aha ke kinoea e hoʻohana ai ka mīkini ʻoki kinoea cnc?

1. He aha ke kinoea e hoʻohana ai ka mīkini ʻoki kinoea cnc?

ʻO ka mīkini ʻoki kinoea cnc he ʻano mea hana e hoʻohana ai i ka wela o ka plasma arc kiʻekiʻe e hoʻoheheʻe i ka wahi (a e hoʻoheheʻe) i ka metala ma ka ʻoki ʻana o ka mea hana, a hoʻohana i ka momentum o ka plasma kiʻekiʻe e wehe i ka mea hoʻoheheʻe. metala e hana i ka ʻoki.ʻOki ʻo Oxygen i nā metala paʻakikī.Hoʻohana maʻamau ka mīkini ʻoki kinoea cnc e hana ana i nā kinoea:

1. Ea

Aia i loko o ka ea ma kahi o 78% nitrogen ma ka leo, no laila, ua like loa ke ʻano o ka slag i hana ʻia e ka ʻoki ʻana i ka ea me ke ʻoki ʻana me ka nitrogen;Eia kekahi, aia ka ea ma kahi o 21% oxygen ma ka nui.He kiʻekiʻe loa ka wikiwiki o ka ʻoki ʻana i nā mea kila māmā;i ka manawa like, ʻo ka ea ke kinoea hana ʻoi loa, a ʻo nā nozzles a me nā electrodes i hoʻohana ʻia he ola lawelawe kiʻekiʻe.

2. Oxygen

ʻO ka mīkini ʻoki kinoea cnc e hoʻohana ana i ka oxygen e like me ke kinoea hana hiki ke hoʻonui i ka wikiwiki o ka ʻoki ʻana i nā mea kila māmā, akā ke hoʻohana wale ʻia ka oxygen no ka ʻoki ʻana, aia ka dross a me kerf oxidation, a haʻahaʻa ke ola o nā electrodes a me nā nozzles. e pili ana i ka pono hana.a e oki ana i na koina.

3. Argon

ʻAʻole paʻa loa ke kinoea Argon me kekahi metala i ka wela kiʻekiʻe, paʻa loa ka argon i hoʻohana ʻia e ka mīkini ʻoki kinoea cnc, a ʻo nā nozzles a me nā electrodes i hoʻohana ʻia he ola lōʻihi.Eia nō naʻe, ʻo ka argon plasma arc he haʻahaʻa haʻahaʻa haʻahaʻa, haʻahaʻa enthalpy, a palena ʻia ka hiki ke ʻoki.Ke hoʻohālikelike ʻia me ka ʻoki ʻana i ka ea, e hoʻemi ʻia ka mānoanoa o ka mīkini ʻoki kinoea cnc ma kahi o 25%.Eia kekahi, ma ke kaiapuni pale argon, ʻoi aku ka nui o ka ʻili o ka metala i hoʻoheheʻe ʻia, ma kahi o 30% ʻoi aku ka kiʻekiʻe ma mua o ke kaiapuni nitrogen, no laila e nui aʻe nā pilikia slag.ʻO ka mīkini ʻoki kinoea cnc me ka hui ʻana o ka argon a me nā kinoea ʻē aʻe hiki ke loaʻa nā pilikia pili i ka slag.ʻO ka hopena, ʻaʻole hoʻohana ʻia ka argon maʻemaʻe wale no ka ʻoki plasma i kēia lā.

4. Hauka

Hoʻohana pinepine ʻia ka hydrogen e like me ke kinoea kōkua e hui pū me nā kinoea ʻē aʻe i hoʻohana ʻia e ka mīkini ʻoki kinoea cnc.No ka laʻana, ʻo ke kinoea H35 kaulana (ʻo ka hapa nui o ka hydrogen he 35%, a ʻo ke koena he argon) ʻo ia kekahi o nā kinoea me ka ikaika o ka ʻoki ʻana i ka plasma arc, ʻo ia ka mea ma muli o ka hydrogen.No ka mea hiki i ka hydrogen ke hoʻonui nui i ka volta arc, he waiwai enthalpy kiʻekiʻe ka jet plasma hydrogen.Ke hoʻohui ʻia me ka argon no ka mīkini ʻoki kino cnc, ʻoi aku ka maikaʻi o ka ʻoki ʻana o ka jet plasma.ʻO ka maʻamau, no nā mea metala me ka mānoanoa o ʻoi aku ma mua o 70mm, hoʻohana mau ʻia ka argon + hydrogen.E like me ka ʻoki ʻana i ke kinoea, inā hoʻohana ʻia ka jet wai e hoʻopili hou i ka argon + hydrogen plasma arc, hiki ke loaʻa ka ʻoki ʻoki kiʻekiʻe i ka wā e ʻoki ai ka mīkini ʻoki kinoea cnc.

5. Nitrogen

ʻO ka Nitrogen he kinoea hana maʻamau no ka mīkini ʻoki kinoea cnc.Ma lalo o ka manaʻo o ka mana kiʻekiʻe o ka mana, ʻoi aku ka maikaʻi o ka nitrogen plasma arc a ʻoi aku ka ikaika o ka jet ma mua o ka argon, ʻoiai ke ʻoki ʻana i nā mea metala wai me ka viscosity kiʻekiʻe e like me I ka hihia o ke kila kila a me ka nickel-based alloys, ka nui o ka slag e kau ana. ma ka ʻaoʻao haʻahaʻa o ka ʻoki liʻiliʻi loa i ka wā e ʻoki ai ka mīkini ʻoki kinoea cnc.Ma ke kaʻina hana ʻoki maoli, ʻōlelo ʻia e koho i kahi kinoea hana kūpono no ka mīkini ʻoki kino cnc e like me kāu mau koi ʻoki ponoʻī a me nā kumukūʻai waiwai.

ʻO ka lua, nā koi o ka mīkini ʻoki plasma ea no ka ea

ʻO ka mīkini ʻoki plasma ea, e like me ka inoa, he mīkini ʻoki plasma e hoʻohana ana i ka ea e like me ke kinoea hana.Loaʻa i ka mīkini ʻoki kinoea cnc kekahi mau koi no ka ea i hoʻohana ʻia:

ʻO ka ea i hoʻohana ʻia e ka mīkini ʻoki kinoea cnc he ea hoʻopaʻa ʻia, e koi ana i ke kinoea e maloʻo a maʻemaʻe, a paʻa ke kahe a me ke kaomi, no ka mea i ka wā o ke kaʻina ʻoki maʻamau o ka mīkini ʻoki kinoea cnc, ke kaomi o ke kinoea. , ka ea paʻa kahe, a me ka maloʻo a me ka maʻemaʻe o ke kinoea i ka hopena pololei.ʻO ka maikaʻi o ka mīkini ʻoki ʻoki kino cnc a inā hiki ke hoʻomaka maʻamau ka arc.Ma keʻano maʻamau, hiki ke nānā ʻia e nā ʻano hana:

1. E nānā inā paha e hoʻomaka ana ka mīkini ʻoki kinoea cnc i nā ʻōlima.Inā hoʻāla ka mīkini ʻoki kinoea cnc, e ʻoluʻolu e hoʻohuli i ke pihi hoʻoponopono ea e hoʻonui i ke kaomi ea.

2. E nānā inā he mea maʻamau ka holo ʻana o ka ea ma ka mīkini ʻoki kinoea cnc, e hoʻohuli i ke kuapo hoʻokuʻu ea e deflate e ʻike inā e hāʻule ka ea kaomi ʻana, inā ʻoi aku ka nui o ka hāʻule ʻana, ʻo ia hoʻi ʻaʻole lawa ka kahe o ka ea. , a laila pono e hoʻohui ʻia kahi pahu mālama kinoea i mua o ka mīkini ʻoki kinoea cnc e hōʻoia i ka holo kinoea;

3. E nānā inā maloʻo a maʻemaʻe ke kinoea, e kaomi i ka lalo o ka mea hoʻokaʻawale aila-wai o ka mīkini ʻoki kinoea cnc, a hoʻokuʻu i waho.Inā nui ka wai keʻokeʻo i loko o ke kinoea i hoʻokuʻu ʻia, ʻo ia ka nui o ka aila a me ka wai i ka lewa.ʻAʻole pono e hoʻohana ʻia kēia ʻano ea.
