摘　　要：以两种铝型材固定挤压垫为研究对象,分析了固定挤压垫与挤压筒位置偏差对铝合金型材表面质量影响的原因。通过生产试验定量掌握了位置偏差值对挤压型材表面质量的影响程度。综合考虑型材的表面质量和生产成本间的平衡,提出了相应条件下的固定挤压垫与挤压筒合理位置偏差的控制范围。Taking two kinds of fixed extrusion pads in aluminum profile as a study object, the reasons for the effect of fixed extrusion pad and the extrusion cylinder position deviation on surface quality of aluminum alloy were analyzed. Through the production test, influencing degree of location deviation on the surface quality of extrusion was mastered quantitatively. Considering the balance between the surface quality of profile and production costs, a reasonable control range of position deviation between the fixed extrusion pad and the container was proposed under corresponding conditions.
