摘　　要：目前国内850t冷剪机压钢装置均采用顶装气缸压钢方式,剪切过程中轧件会频繁跳动,易出现立柱断裂、气缸摆臂断裂、轴套磨损等故障。本文通过对850t冷剪机压钢装置出现的故障进行分析,认为主要原因是压辊中心线离剪机中心线距离较远,造成剪切棒材时容易出现剪切弯头,引发了一系列故障。笔者提出了相应的改进措施,排除了上述的故障,延长了850t冷剪机压钢装置使用寿命,提高了冷床和精整区域设备的作业率,减少了备件消耗,降低了生产成本。The top-mounted cylinder steel pressing method adopted inthe steel pressing device of 850t cold shear machine at presentin China is prone to cause incidents such as column fracture,cylinder swing arm fracture,andshaft sleeve abrasion due to frequent twists of rolled pieces.Through fault analysis of the 850tcold shear machinesteel pressing device,it is concluded that shear distortion of the rolled pieces,often followed by a series of other faults,came as a result of the big distance between the press roll center and the shear center.Targeted improvement measures addressed the faults which prolongs the service life of the steel pressing device of the cold shear machine,raises the operation rate of the system equipment,reduces the consumption of spare parts and lowers production costs as well.
