低熔点合金模具在板料冲压工艺中的应用

The applications of the low melting point alloy die in sheet metal forming

简要介绍了低熔点合金模具的特点及其在板料冲压工艺中的应用 ,对比介绍了两种铸模工艺 ,指出了工艺及模具设计时应注意的问题 ,并以典型大型薄板拉深成形模具为例 ,详细论述了低熔点合金冲压模具的组成及结构特点。

The author introduces the character of low melting point alloy and its applications in sheet metal forming, discusses the choice of the patternmaking material, contrasts the two mould-casting technologies, points out the issues in design of technology and mold, and taking the representative large sheet metal forming for example, specifies the compose and character of the die structure.
