设计简介
摘要
板料折弯机是板材加工、成型的设备之一，特别是在钣金制作公司，经常需要用到这个设备，尤其是在批量加工生产的场合，更是要用到。
该折弯机采用液压系统机构，工作和操作半自动化控制，结构简单，体积较小，与老机型相比，噪声低、功率损失少、工作效率高、板料弯曲角度准确、操作安全可靠、调节方便。适用于板材的直角弯曲，既提高了生产效率和弯曲质量，又简化操作程序，减轻工人劳动强度。
该种折弯机的设计主要涉及弯曲模具的设计和液压系统的设计，折弯机工作部分是弯曲模具，选用“V”形弯曲模具。液压系统主要是为折弯机提供动力，根据弯曲工件所需弯曲力选择电动机、液压泵以及液压缸等一些液压元件。

Abstract
The Benging Machine that technologically advanced and reliable performance,is the preferred one of the sheet metal forming equments.The Bending Machine is widely used in aircraft、automobiles、shipbuilding、electrical machinery and light industries.
The purpose of this graduation project is to design an aluminum row bending machines.The original motives can use electromotor and diesel engines.This bending machine uses the hydraulic system,and manipulation of semiautomatic control,simple structure,relativelysmall.Comparison with the old models,this bending machine has some advantures.Such as low noise,low power loss,high efficiency,accurate angle of aluminum row bending,safeand reliable operation and convenient regulation.For the high-angle beng of sheet metal,it not only increases the production efficiency and quality of bending aluminum row,but also simplifies the proceduresand reduces labor intensity of workers.
The design of the bending machine mainly involves the designs of bending mould and hydraulic system.The work part of the bending machine is bending mould, to choose the "V"-shaped bend mould.Hydraulic system is the impetus for the bending machine.According to the bending force of the bending workpiece to choose the motor,hydraulic pump and hydraulic cylinders and other hydraulic components.
