黑龙江工程学院本科生毕业设计 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 work machinery exists, according to the components request, designed one kind to actuate the unidirectional work using the hydraulic pressure part the booklet .This bender type uses the crank slide organization, has solved during the actual . production the thin plate knee bend And through to the organization movement analysis and the computation, realizes through the organization transformation makes the knee bend strength throughout to maintain on a vertical air conditioning condenser rear cowl production line in the processing process with the components time the special-purpose three Liang two column type non -standard equipment.This is is booklet bender characteristic is the structure simple, the operation easy, the work efficiency is high . Key word : Folds the bender ; Hydraulic pressure ; Non -sign equipment II 黑龙江工程学院本科生毕业设计 黑龙江工程学院本科生毕业设计 目 录 摘 要 Abstract II g m 4 第 一 章 绪 论 i . i 国内外研究现状 1.2 本课题研究的目的与意义 第二章折弯产品的零件图 3 2.1 产品的零件图
