工字钢冷弯机简介：

WGJ250型液压工字钢弯拱机是我厂研制的新式全自动工字钢曲折设备。选用液压体系，具有传动平稳，压力大等特色，能精确定位，大幅度进步地道工字钢加工精度。液压工字钢弯拱机广泛应用于C型钢、工字钢、角钢、槽钢、道轨、方钢、钢管等型钢的拱形卷圆、变径、定角弯曲。使液压操纵系统定位准确，所弯型钢一次自动成型，效率高、操作方便。并且加工精度大，主要应用于隧道，地铁，水电站，地下洞室等。

构造构成：

该设备由主电机、减速器、滚轮、油泵电机、齿轮油泵、溢流阀、电磁换向阀、作业油缸、顶轮及油箱等部件构成。

工作原理

将工字钢放在冷弯机上，与减速带动的滚轮接触后，将压紧手柄进给锁紧，启动电机油泵组，由电动油泵输出的高压溢流阀（可调整所有压力），进入集成块到电缆阀，有电液阀和动点开关（点进，点退）控制油缸工作，工作油缸推进，将工字钢与三个支撑游轮压紧并为发生弯曲变形是时开始计算，油缸推进的长度进程为10mm-15mm,开主电机带动工字钢工作，反复操作，达到所需为止。
