本文介绍国内与日本等国近年来火焰淬火模具钢、硬质合金和钢结硬质合金、粉末高速钢、精密铸造模具材料以及易切削精密模具钢等特殊模具材料的发展和应用情况。一、火焰淬火模具钢为了缩短模具制造周期,便于模具维修、节约能源,采用火焰淬火模具钢是非常有效的,以汽车工业为中心,火焰淬火模具钢在板料冲压中,尤其是使用在冲裁模的刃口部份时得到了广泛而富有成效的应用。
This article introduces the development and application of special mold materials such as flame-quenched mold steel, cemented carbide and steel-bonded cemented carbide, powdery high speed steel, precision casting mold material and free cutting precision mold steel in China and Japan. First, the flame quenching mold steel In order to shorten the mold manufacturing cycle, ease of mold maintenance, energy conservation, the use of flame quenching mold steel is very effective to the automotive industry as the center, flame quenching die steel stamping in sheet metal, especially in the red Cutting edge part of the mold has been extensive and fruitful application.
