摘　　要：介绍了固定挤压垫的优势、国内外发展现状及作用。针对18 MN~100 MN规格挤压机的固定挤压垫在挤压过程中出现的返铝等问题进行了仿真计算分析,结合现场运行情况优化固定挤压垫中锥体垫与锥套的结构尺寸,并对不同硬度的铝合金型材确定了相适应的固定挤压垫结构参数。最终设计的固定挤压垫减少了挤压周期中非挤压时间,提高了生产效率,提高了制品的成品率。The advantages,development status and functions of fixed extrusion pad at home and abroad are introduced.Aiming at the problem of returning aluminum in the extrusion process of the fixed extrusion pad of the 18MN~100MN specification extruder,the simulation calculation and analysis is carried out.Combined with the on-site operation,the structural dimensions of the cone pad and the cone sleeve in the fixed extrusion pad are optimized,and the corresponding structural parameters of the fixed extrusion pad are determined for the aluminum alloy profiles with different hardness.The final design of the fixed extrusion pad reduces the non-extrusion time in the extrusion cycle,improves the production efficiency and improves the yield of the products.
