摘　　要：文章介绍了铝挤压机几种传统的挤压杆固定方式及更换方法,提出了一种适合大型铝挤压机挤压杆的新型的快速更换装置。该装置通过碟簧使挤压杆压盖压紧挤压杆,法兰压盖和动梁固定在一起,简化了动梁结构。同时采用斜楔机构使挤压杆压盖的松开更方便,且减小了高压油缸的尺寸,降低了成本。使用情况表明该装置设计合理、运行可靠。This paper introduces some traditional fixed and replacement method of extrusion rod, puts forwards a new extrusion rod rapid replacement device for large aluminium extrusion press. In the device, the extrusion rod is compressed by extrusion rod gland with disc spring, the flange gland and movable beam are fastened to- gether by screws, so the moving beam structure is simplified. Meanwhile, extrusion rod gland is more easily loosened by inclined wedge mechanism, and the size of high pressure cylinder and the equipment cost are re- duced. Using results show that the device is reasonable and reliable.
