文档介绍：I 摘要在研究国内外折弯机械的发展状况和我国折弯机械存在的问题的基础上, 根据零件作业的要求,设计了一种利用液压元件驱动单向作业的折弯机。该机型采用曲柄滑块机构,解决了实际生产之中薄板材的折弯。并且通过对机构的运动分析和计算, 通过机构的转化来实现使折弯力在加工过程之中始终与零件时刻保持垂直的一台空调冷凝器后罩生产线上专用的三梁二柱式的非标准设备。该折弯机的特点是结构简单,操作容易,工效高。关键词:折弯机液压非标设备 II Abstract In studies the domestic and foreign knee bend machinery the development condition and our country bends at the knees in the question foundation which the machinery exists, according to ponents work request, designed one kind to actuate the unidirectional work using the hydraulic pressure part the booklet type uses the crank anization, has solved during the actual production the thin plate knee through to anization movement analysis and putation, realizes through anization transformation makes the knee bend strength throughout to maintain ona vertical air conditioning condenser rear cowl production line in the processing process with ponents time the special-purpose three Liang two column type non-standard booklet bender characteristic is the structure is simple, the operation is easy, the work efficiency is high. Key word : Folds the bender Hydraulic pressure Non-sign equipment III 目录摘要..........................................................................................................................
