摘　　要：介绍了在铝合金挤压模中采用硬质合金的重要性,提出了一种新型硬质合金挤压模具。这种模具是在挤压模成型的工作部位上采用硬质合金材料进行局部镶嵌,以便于提高模具的耐磨性。以圆管的挤压模作为例子,描述了硬质合金的选择方法,重点介绍了硬质合金的尺寸确定及其镶嵌方法;并根据挤压结果,对普通挤压模与硬质合金挤压模进行了比较。结果表明,使用硬质合金可以大大提高模具的耐磨性和使用寿命。The necessity of using cemented carbide in extrusion die is introduced.A new type of extrusion die is put forward,in which cemented carbide material is used to inlay the working part of the die,so as to improve the wear resistance of the die.The selection of cemented carbide was introduced by taking the actual round tube aluminum profile as an example.The method for determining the size of cemented carbide and the mosaic method of cemented carbide were described.Based on the results of extrusion,the common extrusion die and cemented carbide extrusion die were compared.The results show that the wear resistance of the die can be greatly improved by the use of cemented carbide.Thus the life of the die is greatly improved.
