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。

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 the components work request, designed one kind to actuate the

unidirectional work using the hydraulic pressure part the booklet bender.This 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 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
