Cov ntaub ntawv siv rau hauv kev tsim cov khoom sivstamping tuagsuav nrog hlau, hlau cemented carbide, carbide, zinc alloys, cov ntaub ntawv polymer, aluminium bronze, high thiab low melting point alloys thiab lwm yam. Feem ntau ntawm cov ntaub ntawv siv rau hauv kev tsim cov stamping tuag feem ntau yog hlau. Cov hom ntaub ntawv siv rau cov khoom ua haujlwm ntawm cov tuag yog: carbon tool steel, low alloy tool steel, high carbon high lossis medium chromium tool steel, medium carbon alloy steel, high speed steel, matrix steel thiab carbide, steel cemented carbide, thiab lwm yam.

1. Cov hlau ua haujlwm tsawg

Cov hlau ua cuab yeej uas muaj cov hlau tsis tshua muaj hlau yog ua los ntawm cov hlau ua cuab yeej uas muaj cov hlau carbon thiab ntxiv cov khoom sib xyaw kom raug. Piv nrog cov hlau ua cuab yeej uas muaj cov hlau carbon, nws txo qhov kev tawg thiab kev hloov pauv ntawm cov hlau, ua kom cov hlau tawv dua, thiab kuj zoo dua rau kev hnav. Cov hlau tsis tshua muaj hlau siv rau hauv kev tsim cov pwm yog CrWMn, 9Mn2V, 7CrSiMnMoV (code CH-1), 6CrNiSiMnMoV (code GD) thiab lwm yam.

2. Cov hlau siv ua cov cuab yeej carbon

Ntau daim ntawv thov hauv pwm ntawm cov hlau cuab yeej carbon rau T8A, T10A, thiab lwm yam, qhov zoo ntawm kev ua haujlwm zoo, pheej yig. Tab sis qhov tawv thiab qhov tawv liab tsis zoo, kev kho cua sov deformation, lub peev xwm thauj khoom tsawg.

3. Cov hlau ceev ceev

Cov hlau ceev ceev muaj qhov nyuaj tshaj plaws, tsis kam hnav thiab lub zog compressive tshaj plaws ntawm cov hlau pwm, muaj peev xwm thauj khoom siab. Feem ntau siv rau hauv cov pwm yog W18Cr4V (code 8-4-1) thiab tsawg dua tungsten W6Mo5Cr4V2 (code 6-5-4-2, Tebchaws Meskas hom M2) thiab txhawm rau txhim kho qhov tawv ntawm kev tsim cov hlau ceev ceev 6W6Mo5Cr4V (code 6W6 lossis carbon qis M2). Cov hlau ceev ceev kuj xav tau rov ua dua kom txhim kho lawv cov carbide faib.

4. Cov hlau siv ua cov pa roj carbon nruab nrab chromium siab

Cov hlau siv rau pwm uas muaj cov pa roj carbon ntau thiab cov chromium nruab nrab yog Cr4W2MoV, Cr6WV, Cr5MoV, thiab lwm yam. Cov chromium ntsiab lus tsawg, carbide eutectic tsawg dua, kev faib tawm carbide tsawg, kev kho cua sov deformation me me, muaj zog thiab ruaj khov. Piv nrog rau cov hlau carbide uas muaj cov pa roj carbon ntau thiab cov chromium ntau, kev ua tau zoo dua.

5. Cov hlau siv ua cov pa roj carbon ntau thiab cov chromium ntau

Feem ntau siv cov hlau high-carbon high-chromium tool steel Cr12 thiab Cr12MoV, Cr12Mo1V1 (code D2), lawv muaj qhov nyuaj zoo, tawv thiabhnav tsis kam, kev kho cua sov deformation yog me me heev, rau cov hlau pwm uas hnav tsis kam siab micro-deformation, muaj peev xwm dais tau thib ob tsuas yog cov hlau ceev ceev. Tab sis carbide segregation yog qhov loj heev, yuav tsum tau rov ua dua (axial upsetting, radial drawing) kom hloov forging, txhawm rau txo qhov tsis sib xws ntawm carbide, txhim kho kev siv ntawm kev ua tau zoo.

6. Cemented carbide thiab steel cemented carbide

Qhov tawv thiab hnav tsis kam ntawm cemented carbide siab dua li lwm hom pwm hlau, tab sis lub zog khoov thiab toughness tsis zoo. Cov cemented carbide siv rau pwm yog tungsten thiab cobalt, thiab rau pwm uas muaj kev cuam tshuam me me thiab qhov yuav tsum tau hnav tsis kam siab, cov ntsiab lus cobalt qis dua tuaj yeem siv cemented carbide. Rau pwm uas muaj kev cuam tshuam siab, carbide nrog cov ntsiab lus cobalt siab dua tuaj yeem siv.
