Zvinhu zvinoshandiswa pakugadziramadhiri ekusimbisazvinosanganisira simbi, simbi yakasimwa simende, carbide, zinc based alloys, polymer materials, aluminium bronze, high and low melting point alloys nezvimwewo. Zvizhinji zvezvinhu zvinoshandiswa mukugadzira stamping dies zvinonyanya kuva simbi. Mhando dzezvinhu zvinoshandiswa pakushanda kwema dies ndeidzi: carbon tool steel, low alloy tool steel, high carbon high or medium chromium tool steel, medium carbon alloy steel, high speed steel, matrix steel and carbide, steel cemented carbide, nezvimwewo.

1. Simbi yezvishandiso zvisina chiwanikwa chakawanda

Simbi yemidziyo isina alloy yakawanda inobva pasimbi yemidziyo yekabhoni nekuwedzera huwandu hwakakodzera hwezvinhu zvinosanganisa alloying. Kana tichienzanisa nesimbi yemidziyo yekabhoni, inoderedza maitiro ekutsemuka nekudzima deformation, inovandudza kuomarara kwesimbi, kuramba kupfeka kuri naniwo. Simbi isina alloy yakawanda inoshandiswa mukugadzira maforoma ndiCrWMn, 9Mn2V, 7CrSiMnMoV (kodhi CH-1), 6CrNiSiMnMoV (kodhi GD) nezvimwewo.

2. Simbi yesimbi yekabhoni

Mashandisirwo akawanda musimbi yekabhoni yekushandisa T8A, T10A, nezvimwewo, mabhenefiti ekushanda zvakanaka, akachipa. Asi kuomarara uye kuomarara kutsvuku hakuna kunaka, kushanduka kwekupisa, uye mutoro wakaderera.

3. Simbi inomhanya zvakanyanya

Simbi inomhanya zvikuru ine kuoma kwakanyanya, kuramba kupfeka uye simba rekudzvanya resimbi yeforoma, kugona kwakanyanya kutakura mutoro. Inowanzoshandiswa muforoma ndiW18Cr4V (kodhi 8-4-1) uye tungsten shoma W6Mo5Cr4V2 (kodhi 6-5-4-2, iyo United States brand M2) uye kuvandudza kusimba kwekugadzirwa kwesimbi inokurumidza 6W6Mo5Cr4V ine kabhoni shoma. Simbi dzinomhanya zvakanyanya dzinodawo kugadziriswa kuti dzivandudze kugoverwa kwadzo kwekabhoni.

4. Simbi dzemidziyo ine kabhoni yakawanda yepakati-chromium

Simbi dzesimbi dzine chromium yakawanda inoshandiswa pakuumba ndiCr4W2MoV, Cr6WV, Cr5MoV, nezvimwewo, huwandu hwadzo hwechromium hwakaderera, carbide shoma, carbide yakapararira, kupisa kwayo kwakaderera, ine kusimba kwakanaka uye kugadzikana kwakaenzana. Kana tichienzanisa nekupatsanurwa kwecarbide, simbi ine chromium yakawanda yakakora, mashandiro ayo akavandudzika.

5. Simbi yekushandisa ine kabhoni yakawanda ine chromium yakawanda

Inowanzoshandiswa simbi yesimbi ine kabhoni yakawanda ine chromium Cr12 neCr12MoV, Cr12Mo1V1 (kodhi D2), ine kusimba kwakanaka, kusimba uyekuramba kupfeka, Kuchinja kwekupisa kwesimbi kudiki kwazvo, simbi yekuumbwa isingapfeki zvakanyanya, ine simba rekutakura rinouya mushure mesimbi inomhanya zvakanyanya. Asi kupatsanurwa kwecarbide kwakakomba, kunofanira kugara kuchidzokororwa (kudzokororwa kweaxial, kudhirowa kweradial) kuti kuchinje forging, kuitira kuderedza kusaenzana kwecarbide, uye kuvandudza mashandiro ayo.

6. Carbide yakagadzirwa nesimende uye carbide yakagadzirwa nesimende yesimbi

Kuomarara uye kuramba kupfeka kwecarbide yakagadzirwa nesimbi kwakakwira kupfuura chero imwe mhando yesimbi yesimbi, asi simba rekukotama uye kusimba kwakaderera. Carbide yakagadzirwa nesimbi inoshandiswa pakugadzira maforoma i tungsten ne cobalt, uye kune maforoma ane simba diki uye anodzivirira kupfeka zvakanyanya, cobalt yakaderera inogona kushandiswa. Kune maforoma ane simba guru, carbide ine cobalt yakawanda inogona kushandiswa.
