Ko ngā taputapu kāpira sima te nuinga o ngā taputapu mīhini CNC. I ētahi whenua, neke atu i te 90% o ngā taputapu huri me te neke atu i te 55% o ngā taputapu mira he mea hanga ki te kāpira sima. Hei tāpiri, he mea noa te whakamahi i te kāpira sima hei hanga taputapu whānui pērā i ngā wiri me ngā taputapu mira mata. Kei te piki haere hoki te whakamahinga o te kāpira sima i roto i ngā taputapu uaua pērā i ngā riimana, ngā mira mutunga, ngā taputapu tapahi modulus waenga me te nui mō te mīhini i ngā mata niho whakapakeke, me ngā poro. Ko te pai o te tapahi o ngā taputapu kāpira sima he 5 ki te 8 ngā wā i te pai o ngā taputapu maitai tere-rahi (HSS). Ko te nui o te konganuku i tangohia mō ia waeine o te ihirangi tungsten he tata ki te 5 ngā wā nui ake i te HSS. Nō reira, ko te whakamahi whānui i te kāpira sima hei rauemi taputapu tētahi o ngā huarahi tino whai hua ki te whakamahi pai i ngā rauemi, te whakapai ake i te hua tapahi, me te whakarei ake i ngā painga ōhanga.
Te Whakarōpūtanga o ngā Rauemi Utauta Carbide Simented
I runga i te hanganga matū matua, ka taea te wehewehe i te waro sima ki te waro sima e ahu mai ana i te waro tungsten me te waro sima e ahu mai ana i te titanium carbonitride (Ti(C,N)), e whakaaturia ana i te Ripanga 3-1.
Kei roto i te kāpira sima i hangaia ki te kāpira tungsten:
Tungsten-cobalt (YG)
Tungsten-cobalt-titanium (YT)
Me ngā warowaihā onge (YW) kua tāpirihia
He painga, he ngoikoretanga anō hoki tō ia momo. Ko ngā kāpia i tāpirihia ko te kāpia tungsten (WC), te kāpia titanium (TiC), te kāpia tantalum (TaC), te kāpia niobium (NbC), me ētahi atu, ko te cobalt (Co) te wāhanga here whakarewa e whakamahia whānuitia ana.
Ko te waro sima i hangaia i te titanium carbonitride he mea hanga tuatahi ki te TiC (ko ētahi he waro, he nitride rānei kua tāpirihia), me te molybdenum (Mo) me te nickel (Ni) hei wāhanga here whakarewa e whakamahia whānuitia ana.
I runga i te rahi o te kōpura, ka taea te whakarōpū i te kāpira sima kia:
Karāhe sima noa
Karāhe sima pai-kikokore
Karāhe sima tino pai rawa
E ai ki te GB/T 2075—2007, ko ngā tohu reta e whai ake nei:
HW: He kāpira sima kāore i pania, kei roto ko te kāpira tungsten (WC) te nuinga, he rahi te kōpura o te ≥1μm
HF: He kāpira sima kāore i pania, kei roto ko te kāpira tungsten (WC) te nuinga, he rahi kōpura <1μm
HT: He kāpira sima kāore i pania, kei roto ko te kāpira titanium (TiC) te kāpira titanium nitride rānei (TiN) me ērā e rua (e mōhiotia ana ko te cermet)
HC: Ngā warowaiha sima kua whakahuatia ake nei me te paninga
E toru ngā wāhanga o te International Organization for Standardization (ISO) mō te tapahi i ngā warowaiha sima:
Akomanga K (K10 ki K40):
He rite ki te akomanga YG o Haina (ko te nuinga he WC-Co)
Akomanga P (P01 ki P50):
He rite ki te akomanga YT o Haina (ko te nuinga he WC-TiC-Co)
Akomanga M (M10 ki M40):
He rite ki te akomanga YW o Haina (ko te nuinga he WC-TiC-TaC(NbC)-Co)
Ko ngā māka o ia kāwai e tohuhia ana e te tau i waenga i te 01 me te 50, e tohu ana i te raupapa o ngā koranu mai i te pakeketanga teitei ki te pakaritanga nui rawa atu, hei whiriwhiri i roto i ngā tukanga tapahi me ngā āhuatanga miihini mō ngā rauemi mahi rerekē. Mena e tika ana, ka taea te whakauru i tētahi waehere takawaenga i waenga i ngā waehere whakarōpūtanga e rua e tata ana, pērā i te P15 i waenga i te P10 me te P20, te K25 rānei i waenga i te K20 me te K30, engari kaua e neke atu i te kotahi. I ngā wā motuhake, ka taea te wehewehe anō i te waehere whakarōpūtanga P01 mā te tāpiri i tētahi atu mati i wehea e te ira tekau, pērā i te P01.1, P01.2, me ētahi atu, hei wehewehe anō i te ātete kakahu me te pakari o ngā rauemi mō ngā mahi whakaoti.
Te Mahi a ngā Rauemi Utauta Carbide Simented
1. Te Pakari He nui ngā warowaiha mārō kei roto i te kāpira sima (pērā i te WC, TiC), ā, he nui ake tōna pakari i ērā o ngā rauemi maitai tere-rahi. Ko te teitei ake o te pakari o te kāpira sima, ko te pai ake o tōna ātete ki te kakahu, he nui ake i ērā o te maitai tere-rahi.
Ka iti ake te mārō o te koranu ka nui ake te ihirangi o te wāhanga here cobalt.
Nā te mea he mārō ake te TiC i te WC, he nui ake te mārō o ngā koranu WC-TiC-Co i ngā koranu WC-Co. Ka nui ake te mārō o te TiC.
Mā te tāpiri i te TaC ki ngā koranu WC-Co ka piki ake te pakeke mā te 40 ki te 100 HV; mā te tāpiri i te NbC ka piki ake mā te 70 ki te 150 HV.
2. KahaKo te kaha piko o te waro sima he tata ki te 1/3 ki te 1/2 noa iho i te kaha piko o ngā rauemi maitai tere-rahi.
Ka nui ake te kaha o te koranu ka nui ake te nui o te cobalt.
He iti ake te kaha o ngā koranu kei roto he TiC i ērā kāore he TiC; ka iti ake te kaha ina nui ake te TiC.
Mā te tāpiri i te TaC ki te kāpira sima WC-TiC-Co ka whakanui ake i tōna kaha piko, ā, ka tino whakarei ake i te ātete o te mata tapahi ki te pakaru me te pakaru. I te pikinga ake o te ihirangi TaC, ka pai ake hoki te kaha ngenge.
Ko te kaha pēhi o te waro sima he 30% ki te 50% teitei ake i te maitai tere-rahi.
3. Te Pakari He iti iho te pakari o te waro sima i tō te maitai tere-rahi.
He iti ake te pakari o ngā koranu kei roto he TiC i ērā kāore he TiC; i te pikinga ake o te nui o te TiC, ka heke te pakari.
I roto i ngā koranu WC-TiC-Co, mā te tāpiri i te nui tika o te TaC ka taea te whakanui ake i te pakari mā te 10% me te pupuri tonu i te ātete wera me te ātete kakahu.
Nā te iti o tōna pakari, kāore te waro sima i te pai mō ngā āhuatanga he kaha ngā pānga, he wiri rānei, inā koa i ngā tere tapahi iti ina he kaha rawa te piri me te pakaru.
4. Ngā Āhuatanga Ā-Whā Ko te kawe wera o te waro sima e 2 ki te 3 ngā wā teitei ake i tērā o te maitai tere-rahi.
Nā te mea he iti iho te kawe wera o te TiC i tō te WC, he iti ake te kawe wera o ngā koranu WC-TiC-Co i ngā koranu WC-Co. Ko te nui ake o te TiC, ko te iti ake o te kawe wera.
5. Ātete Wera He nui ake te ātete wera o te karāhe sima i te maitai tere-teitei, ā, ka taea te tapahi i te 800 ki te 1000°C me te ātete pai ki te whakarerekētanga kirihou i ngā pāmahana teitei.
Mā te tāpiri i te TiC ka piki ake te pakeketanga o te pāmahana teitei. Nā te mea he teitei ake te pāmahana whakangawari o te TiC i te WC, ka puhoi ake te hekenga o te pakeketanga o ngā koranu WC-TiC-Co i te pāmahana i ngā koranu WC-Co. Ka nui ake te TiC, ka iti ake hoki te cobalt, ka iti ake te hekenga.
Mā te tāpiri i te TaC, i te NbC rānei (me ngā pāmahana whakangawari teitei ake i te TiC) ka whakanui ake i te pakeketanga me te kaha o te pāmahana tiketike.
6. Ngā Āhuatanga Ārai-Pīpiri He teitei ake te pāmahana piri o te waro sima i tērā o te maitai tere-teitei, ā, he pai ake te ātete ki te kakahu piri.
He iti iho te pāmahana piri o te kobalt ki te maitai i te WC; i te pikinga ake o te nui o te kobalt, ka heke te pāmahana piri.
He teitei ake te pāmahana piri o te TiC i ngā WC, nō reira he teitei ake te pāmahana piri o ngā koranu WC-TiC-Co (tata ki te 100°C teitei ake) i ngā koranu WC-Co. Ka whakaitihia te piri e te TiO2 i hangaia i ngā pāmahana teitei i te wā tapahi.
He teitei ake ngā pāmahana piri o TaC me NbC i te TiC, ā, ka pai ake ngā āhuatanga ārai-piri. He iti noa iho te kaha o TaC ki ngā rauemi mahi, arā, he iti noa iho i te tekau o ngā WC.
7. Te Pūmautanga Matū He hononga tata te ātete ki te kakahu o ngā taputapu waro sima ki tōna pumau ā-tinana me te pumau matū i ngā pāmahana mahi.
He teitei ake te pāmahana waikura o te waro sima i tērā o te maitai tere-tiketike.
He teitei ake te pāmahana waikura o TiC i ngā WC, nō reira he iti ake te taumaha waikura o ngā koranu WC-TiC-Co i ngā pāmahana teitei i ngā koranu WC-Co; ka nui ake te TiC, ka kaha ake te ātete waikura.
He teitei ake hoki te pāmahana waikura o te TaC i ngā WC, ā, kua pai ake te ātete o ngā koranu kei roto ko te TaC me te NbC ki te waikura i te pāmahana teitei. Heoi, mā te nui ake o te konukōre ka māmā ake te waikura.
