Hoʻohana nui ʻia ke kila kila no ka stamping, blanking, hoʻokumu ʻana, bending, extrusion anu, kiʻi anuanu, pauda metallurgy make, etc. Pono ka paʻakikī kiʻekiʻe, ke kūpaʻa ʻaʻahu kiʻekiʻe a me ka paʻakikī. Māhele maʻamau i ʻelua ʻano: ʻano maʻamau a me ke ʻano kūikawā. No ka laʻana, ʻo ka hana maʻamau maʻamau maʻamau maʻamau i ʻAmelika Hui Pū ʻIa e loaʻa i nā māka kila ʻehā: 01, A2, D2, a me D3. Hōʻike ʻia ka hoʻohālikelike ʻana o nā māka kila o ke kila kila ma nā ʻāina like ʻole ma ka Papa 4. E like me ka Japanese JIS standard, ʻo nā ʻano nui o ke kila hana anuanu e hiki ke hoʻohana ʻia ʻo SK series, me SK series. kila kila kila, 8 SKD moʻo kila kila, a me 9 SKHMO pūʻulu kila māmā holo, no ka huina o 24 mau māka kila. ʻO ke kūlana kila kila GB/T1299-2000 o Kina he 11 mau ʻano kila, e hana ana i kahi moʻo piha piha. Me nā hoʻololi o ka ʻenehana hana, nā mea i hana ʻia a me nā koi no nā mold, ʻaʻole hiki i ka moʻo kumu kumu ke hoʻokō i nā pono. Kepani kila wili a me ka nui Europa mea paahana a me ka make kila Manufacturers ua hoʻomōhala kūikawā-kumu hana anu make kila, a lohi i hoʻokumu Respective anu hana make kila moʻo, ka hooulu ana o keia mau hana anu make steels no hoi ka hooulu ana o ke anu hana make kila.
Haʻahaʻa alloy ea quenching anu hana make kila
Me ka hoʻomohala ʻana i ka ʻenehana lapaʻau wela, ʻoi aku ka nui o ka hoʻohana ʻana i ka ʻenehana hoʻoheheʻe ʻana i ka ʻenekini i loko o ka ʻoihana mold, i mea e hōʻemi ai i ka deformation quenching, ua hoʻomohala ʻia kekahi mau haʻahaʻa haʻahaʻa ea-quenched micro-deformation steels ma ka home a ma waho. Pono kēia ʻano kila i ka hardenability maikaʻi a me ka mālama wela He liʻiliʻi deformation, ikaika maikaʻi a me ka paʻakikī, a loaʻa i kekahi mau lole pale. ʻOiai ʻo ke kila kila (e like me D2, A2) maʻamau ka paʻakikī paʻakikī, loaʻa nā mea hao kiʻekiʻe a he pipiʻi. No laila, ua hoʻomohala ʻia kekahi mau kila micro-deformation haʻahaʻa ma ka home a ma waho. Loaʻa i kēia ʻano kila nā mea hoʻoheheʻe Cr a me Mn i mea e hoʻomaikaʻi ai i ka paʻakikī. ʻO ka nui o ka maʻiʻo o nā mea hoʻohui i ka maʻamau <5%. He kūpono ia no ka hana ʻana i nā ʻāpana kikoʻī me nā pahu hana liʻiliʻi. ʻO nā poni paʻakikī. ʻO nā māka kila o ka Lunamakaainana he A6 mai ʻAmelika Hui Pū ʻIa, ACD37 mai Hitachi Metals, G04 mai Daido Special Steel, AKS3 mai Aichi Steel, a me nā mea ʻē aʻe. o ka austenite paʻa a loaʻa iā ia ka ikaika maikaʻi, ka paʻakikī a me ke kūpaʻa dimensional. Hiki ke hoʻohana ʻia e hana i nā mea hoʻoheheʻe anu anu i hiki ke ʻoki a haki. Ke ola lawelawe kiʻekiʻe.
Ke kila hoʻoheheʻe ʻia i ke ahi
I mea e hōʻemi ai i ka pōʻaiapuni o ka hana ʻana, e hoʻomaʻamaʻa i ke kaʻina hana wela, mālama i ka ikehu a hoʻemi i ke kumukūʻai hana o ka mold. Ua hoʻomohala ʻo Iapana i kekahi mau kila make hana anu kūikawā no nā koi kinai ahi. ʻO nā mea maʻamau ka Aichi Steel's SX105V (7CrSiMnMoV), SX4 (Cr8), Hitachi Metal's HMD5, HMD1, Datong Special Steel Company's G05 steel, etc. Ua hoʻomohala ʻo Kina i 7Cr7SiMnMoV. Hiki ke hoʻohana ʻia kēia ʻano kila no ka hoʻomehana ʻana i ka ʻili a i ʻole nā ʻāpana ʻē aʻe o ka ʻōpala me ka hoʻohana ʻana i kahi pū puhi oxyacetylene a i ʻole nā mea hoʻomehana ʻē aʻe ma hope o ka hana ʻana o ka ʻōpala a laila hoʻoheheʻe ʻia ka ea a kinai. ʻO ka maʻamau, hiki ke hoʻohana pololei ma hope o ke kinai ʻana. Ma muli o kāna hana maʻalahi, hoʻohana nui ʻia ia ma Iapana. ʻO 7CrSiMnMoV ke ʻano kila kila o kēia ʻano kila, nona ka paʻakikī maikaʻi. Ke hoʻopauʻia kaʻaila φ80mm, hiki i ka paʻakikī ma kahi mamao o 30mm mai kaʻili ke hiki i 60HRC. ʻO ka ʻokoʻa o ka paʻakikī ma waena o ke kumu a me ka ʻili he 3HRC. Ke hoʻopauʻia ka lapalapa ahi, Ma hope o ka hoʻonāʻana i ka 180 ~ 200 ° C a me ka hoʻomehanaʻana i ka 900-1000 ° C no ka hoʻopauʻana me ka pū puhi, hiki i ka paʻakikī ke piʻi ma luna o 60HRC a hiki ke loaʻa kahi papa paʻakikī ma luna o 1.5mm.
High toughness, kiʻekiʻe aahu pale anuanu hana make kila
I mea e hoʻomaikaʻi ai i ka paʻakikī o ka hana anuanu make kila a hōʻemi i ke kūpaʻa ʻana o ke kila, ua hoʻomohala kekahi mau ʻoihana hoʻoheheʻe hao nui ʻē aʻe i kahi ʻano o nā mea hao hana anuanu me ka paʻakikī kiʻekiʻe a me ke kūpaʻa kiʻekiʻe. Loaʻa kēia ʻano kila ma kahi o 1% kalapona a me 8% Cr. Me ka hoʻohui ʻana o Mo, V, Si a me nā mea hoʻohui ʻē aʻe, ʻoi aku ka maikaʻi o kāna carbide, puʻunaue like ʻia, a ʻoi aku ka kiʻekiʻe o kona paʻakikī ma mua o ke kila ʻano Cr12, ʻoiai ʻo kona pale ʻana e like. . ʻO ko lākou paʻakikī, ka ikaika flexural, ka ikaika luhi a me ka paʻakikī haʻihaʻi he kiʻekiʻe, a ʻoi aku ka kiʻekiʻe o ko lākou kūpaʻa anti-temper ma mua o ka Crl2 type mold steel. He kūpono lākou no nā kuʻi kiʻekiʻe a me nā punches multi-station. ʻO nā ʻano kila ʻokoʻa o kēia ʻano kila ʻo Iapana DC53 me ka haʻahaʻa V maʻiʻo a me CRU-WEAR me ka V kiʻekiʻe. Hoʻopiʻiʻia ka DC53 ma 1020-1040 ° C a hiki i ka paʻakikī ke hiki i 62-63HRC ma hope o ka hoʻomahaʻana o ka ea. Hiki ke hoʻohaʻahaʻa i ka wela haʻahaʻa (180 ~ 200 ℃) a me ka mahana wela kiʻekiʻe (500 ~ 550 ℃), hiki i kona paʻakikī ke 1 mau manawa kiʻekiʻe ma mua o D2, a ʻo kāna hana luhi he 20% kiʻekiʻe ma mua o D2; ma hope o CRU-WEAR forging and rolling, it is annealed and austenitized at 850-870 ℃. Ma lalo o 30 ℃ / hola, hoʻoluʻu i ka 650 ℃ a hoʻokuʻu ʻia, hiki i ka paʻakikī ke hiki i 225-255HB, hiki ke koho ʻia ka mahana hoʻopio ma ka laulā o 1020 ~ 1120 ℃, hiki i ka paʻakikī ke piʻi i 63HRC, hoʻonā ʻia ma 480 ~ 570 ℃ e like me i nā kūlana hoʻohana, me ke kūlana lua ʻoi aku ka maikaʻi o ka hopena paʻakikī, ke kūpaʻa a me ka paʻakikī ma mua o D2.
Ke kila kumu (Ke kila māmā holo kiʻekiʻe)
Ua hoʻohana nui ʻia ke kila kiʻekiʻe ma nā ʻāina ʻē no ka hana kiʻekiʻe kiʻekiʻe, lōʻihi ka lōʻihi o ka hana anuanu ma muli o kona kūpaʻa maikaʻi a me ka ʻulaʻula ʻulaʻula, e like me ke kila kiʻekiʻe SKH51 (W6Mo5Cr4V2) maʻamau o Iapana. No ka hoʻololiʻana i nā koi o ka mold, hoʻonui pinepineʻia ka paʻakikī ma ka ho'ēmiʻana i ka mahana wela, ka paʻakikī paʻakikī a iʻole ka hoʻohaʻahaʻaʻana i ke kalapona i ke kila kiʻekiʻe. Hoʻokumu ʻia ke kila Matrix mai ke kila kiʻekiʻe, a ua like kona haku mele me ke kila matrix o ke kila kiʻekiʻe ma hope o ke kinai ʻana. No laila, he liʻiliʻi ka helu o nā carbide koena ma hope o ke kinai ʻana, e hoʻomaikaʻi nui i ka paʻakikī o ke kila i hoʻohālikelike ʻia me ke kila kiʻekiʻe. Ua aʻo ʻo ʻAmelika Hui Pū ʻIa a me Iapana i nā kila kumu me nā māka VascoMA, VascoMatrix1 a me MOD2 i nā makahiki 1970. I kēia mau lā, ua kūkulu ʻia ʻo DRM1, DRM2, DRM3, etc. Hoʻohana maʻamau no nā ʻano hana anu e koi ai i ka paʻakikī kiʻekiʻe a me ke kūpaʻa anti-temper maikaʻi. Ua hoʻomohala ʻo Kina i kekahi mau kila kumu, e like me 65Nb (65Cr4W3Mo2VNb), 65W8Cr4VTi, 65Cr5Mo3W2VSiTi a me nā kila ʻē aʻe. ʻO kēia ʻano kila he ikaika maikaʻi a paʻakikī a hoʻohana nui ʻia i ka extrusion anu, ke kuʻi anuanu o ka pā mānoanoa, nā huila ʻōwili, make ka manaʻo, make ke poʻo anu, a me nā mea ʻē aʻe, a hiki ke hoʻohana ʻia e like me ka wela extrusion make.
ʻO ke kila hoʻoheheʻe ʻia ka pauka
ʻO ka LEDB-type high-alloy anu hana make kila i hana ʻia e nā kaʻina hana maʻamau, ʻoi aku ka nui o nā mea ʻāpana, loaʻa nā carbide eutectic coarse a me ka hāʻawi ʻole ʻana, e hōʻemi nui ana i ka paʻakikī, grindability a me isotropy o ke kila. I nā makahiki i hala iho nei, nui nā hui kila kūikawā o nā ʻāina ʻē e hana ana i ka mea hana a me ke kila make i ka hoʻomohala ʻana i kahi moʻo o ka pauka metallurgy kiʻekiʻe-wikiwiki a me kiʻekiʻe-alloy make kila, i alakaʻi i ka ulu wikiwiki o kēia ʻano kila. Ke hoʻohana nei i ke kaʻina hana metallurgy pauka, hoʻomaʻalili koke ka pauka hao atomized a maikaʻi a maikaʻi nā carbide i hana ʻia, e hoʻomaikaʻi nui i ka paʻakikī, grindability a me ka isotropy o ka mea mold. Ma muli o kēia kaʻina hana kūikawā, ua maikaʻi nā carbide a me nā mea likeʻole, a ua hoʻonuiʻia ka hana machinability a me ka wiliʻana, eʻae ana i ke kalapona kiʻekiʻe a me ka vanadium e hoʻohuiʻia i ke kila, a pēlā e hoʻomohala ai i nāʻano kila hou. No ka laʻana, ʻo ka moʻo DEX o Datong o Iapana (DEX40, DEX60, DEX80, a me nā mea ʻē aʻe), ʻo Hitachi Metal's HAP series, Fujikoshi's FAX series, UDDEHOLM's VANADIS series, France's Erasteel's ASP series, a me ka ʻoihana ʻAmelika CRUCIBLE o ka hui ʻo ʻAmelika Hui Pū ʻIa e hoʻomohala nei i ka mea hao hao a make koke. . Ke hoʻokumu nei i kahi pūʻulu o nā mea hao pauka e like me CPMlV, CPM3V, CPMlOV, CPM15V, a me nā mea ʻē aʻe, ua hoʻomaikaʻi maikaʻi ʻia ko lākou pale ʻana a me ka paʻakikī i ka hoʻohālikelike ʻia i ka mea hana a me ke kila make i hana ʻia e nā kaʻina hana maʻamau.
