Zvinhu zvinoshandiswa pakugadzirakutsika kunofazvinosanganisira simbi, simbi cemented carbide, carbide, zinc based alloys, polymer zvinhu, aluminium bronze, yakakwirira uye yakaderera melting point alloys uye zvichingodaro.Zvizhinji zvezvinhu zvinoshandiswa pakugadzira zvidhindo zvinofa zvakanyanya simbi.Mhando dzakajairwa dzezvishandiso zvinoshandiswa pazvikamu zvekushanda zvemafa ndeaya: kabhoni mudziyo simbi, yakaderera alloy chishandiso simbi, yakakwira kabhoni yakakwira kana yepakati chromium chishandiso simbi, yepakati kabhoni alloy simbi, inomhanya simbi, matrix simbi uye carbide, simbi simende carbide, etc.

1. Low-alloy tool simbi

Low-alloy tool simbi inobva pa carbon tool simbi pamwe nekuwedzera kwehuwandu hwakakodzera hwezvinhu zvinosanganiswa.Kuenzaniswa nekabhoni mudziyo simbi, kuderedza tsika yekutsemuka uye kudzima deformation, kunatsiridza kuoma kwesimbi, kupfeka kuramba kuri nani zvakare.Yakaderera-alloy simbi inoshandiswa mukugadzira molds ndeye CrWMn, 9Mn2V, 7CrSiMnMoV (code CH-1), 6CrNiSiMnMoV (code GD) nezvimwewo.

2. Carbon tool simbi

Zvimwe zvikumbiro mu mold ye carbon tool simbi ye T8A, T10A, nezvimwewo, zvakanakira kuita kwakanaka kwekugadzirisa, zvakachipa.Asi kuoma uye kuomarara kwakatsvuka kwakashata, kupisa kurapwa deformation, kuderera-kuremerwa simba.

3. Simbi yepamusoro-soro

Simbi yepamusoro-soro ine kuomarara kwepamusoro, kupfeka kusagadzikana uye kumanikidza kusimba kwesimbi yekuumbwa, yakakwirira inotakura mutoro.Inowanzo shandiswa mukuumbwa ndeye W18Cr4V (code 8-4-1) uye shoma tungsten W6Mo5Cr4V2 (code 6-5-4-2, iyo United States brand M2) uye kugadzirisa kuoma kwekuvandudzwa kweyakaderedzwa kabhoni vanadium high-speed steel. 6W6Mo5Cr4V (code 6W6 kana pasi kabhoni M2).Masimbi ekumhanya kwazvo anodawo kuumbwazve kuvandudza kugovera kwavo carbide.

4. High-carbon medium-chromium tool steels

High-carbon medium-chromium tool steels anoshandiswa kugadzira molds ndeye Cr4W2MoV, Cr6WV, Cr5MoV, nezvimwewo, yavo chromium yakaderera, shoma eutectic carbide, carbide kugovera, kupisa kupisa deformation idiki, ine kunaka kuomarara uye kugadzikana kwedimensional.Kuenzaniswa necarbide segregation inenge yakakomba yakakwira kabhoni yakakwira chromium simbi, kuita kwacho kwave nani.

5. High-carbon high-chromium tool simbi

Inowanzo shandiswa high-carbon high-chromium tool Cr12 uye Cr12MoV, Cr12Mo1V1 (code D2), vane kunaka kuoma, kuoma uyekupfeka kuramba, kupisa kupisa deformation idiki kwazvo, yekukwirira kupfeka kupikisa micro-deformation mold simbi, inotakura kugona kwechipiri kune yakakwirira-kumhanya simbi.Asi kupatsanurwa kwecarbide kwakakomba, kunofanira kuramba kuchigumburwa (axial upsetting, radial drawing) kushandura kuumba, kuitira kuderedza kusaenzana kwecarbide, kuvandudza kushandiswa kwekushanda.

6. Simende carbide uye simbi simende carbide

Iko kuomarara uye kupfeka kuramba kwecemented carbide kwakakwira kupfuura iyo chero imwe mhando yesimbi yeforoma, asi simba rekukotama uye kuoma kwakashata.Iyo yakasimwa carbide inoshandiswa kugadzira mold ndeye tungsten uye cobalt, uye kune molds ine diki diki uye yakakwirira kupfeka inodiwa zvinodiwa, yakaderera cobalt yemukati simende carbide inogona kushandiswa.Kune akanyanya kukanganisa mold, carbide ine yakakwira cobalt yemukati inogona kushandiswa.
