一前言贝氏体钢板是制造“贝氏体钢板模”的关键材料。所谓“贝氏体钢板模”即在预先用普通碳钢,如 A_3钢、45~#钢或球墨铸铁、锌基合金等材料制作的基体凹模(若用碳钢或球铁制作的,则不需要热处理)上,用沉头螺钉或粘结剂固定一块相应大小的“贝氏体钢板”,然后安装在模架上,用已热处理的凸模冲出凹模型孔,即作为冲裁模使用的模具。这块冲有凹模型孔的“贝氏体钢板”就在基体凹模表面作为刃口层。
A preface Bainitic steel sheet is the key material for making “bainitic steel sheet mold”. The so-called “bainitic steel mold” that is pre-ordinary carbon steel, such as A_3 steel, 45 ~ # steel or ductile iron, zinc-based alloy and other materials made of matrix die (if made of carbon steel or ductile iron, then Do not need heat treatment), with a countersunk head screw or adhesive to fix a corresponding size of “bainitic steel”, and then installed in the mold base, with a heat-treated punch punch out of the hole, that is, as blanking die Used mold. The “bainitic steel plate” punched with a concave mold hole is on the surface of the base concave mold as a blade layer.
