某厂1600剪切机,是国产首台具有液压压板和液压平衡机构的浮动轴剪切机,其最大设计剪切力为1600吨力。投产以来,该剪机机架存在明显晃振、恶化了剪机的工作条件、妨碍了剪机的能力发挥。本文介绍为查明剪机实际工况和机架晃振原因而进行的工程测试和诊断。 A plant 1600 shears, is the first domestic made with a hydraulic pressure plate and hydraulic balance mechanism of the floating shaft shears, the maximum design shear force of 1600 tons of force. Put into production, the shearing machine rack obvious shake, deteriorating the working conditions of the shears, hinder the ability of the clipper to play. This article describes engineering tests and diagnostics to verify the actual conditions of the shears and the reasons for rack shake.
