摘　　要：50MN水压机是某铝厂最大吨位的挤压机,由于设备陈旧老化,自动化程度低、生产效率低、产品质量差,设备亟需改造。本文以挤压机四根张力柱作为测试对象,设计合理测试方案,使用静态电阻应变仪在挤压机实际生产过程中测试张力柱的应力应变,对比设备改造前后测试结果,确认四根张力柱的应力状态是否均布,从而提高设备的使用安全性。50MN hydraulic machine is the largest horizontal extruder in the Aluminum Company,due to equipment obsolescence,the device needs to be improved for low automation,low produce efficiency,poor product quality. In this paper,four tension column as a test object,designed test program,using the static resistance strain gauges actual production process in the extruder to test the stress-strain of tension column,compared before with after the equipment test,transformation test results to confirmed four tension column is uniform stress state,thereby increasing the use of safety equipment.
