联系人：普斯威德金属挤压液压机运行中，有时会有螺栓脱落，掉入液压缸内对柱塞壁造成严重划伤。问题出现后，传统方法根本无法实现现场修复，只能是拆卸后运往生产厂家进行补焊加工或报废更换。由于没有备件更换，重新生产配件或返厂维修时间无法掌控，长时间停机给企业造成严重经济损失，同时还要支付高额的加工或修复费用。为了满足企业连续化生产的要求，需要找到方便快捷、简单有效的维修手段来解决该设备问题，减少企业的停机停产时间并降低维修维护费用。可以采用高分子复合材料的方法进行现场修复

1．用氧-乙炔火焰烤划伤部位（掌握温度，避免表面退火），将常年渗金属表面的油烤出来，烤到没有火花四溅。
2．将划伤部位用角磨机表面处理，打磨深度1毫米以上，并沿缸筒外壁打磨出沟槽，是燕尾槽。划伤两端钻孔加深，改变受力情况。
3．用脱脂棉蘸丙酮或无水乙醇将表面清洗干净。

14单柱式液压机受力分析

单柱式液压机机架可按其对称面简化为平面机架，其受力简图可堪称平面曲杆和直杆的组合，如图所示。
曲杆O-O部分主要受轴向力和弯矩的作用，剪力可忽略不计。根据曲杆的计算公式，在O-O段任一截面（由角度θ定）的弯矩M及轴向力N分别为DBDA20K1X/25V
