1 主机

    l  主要构件采用UGS/ANSYS/CAD三维有限元分析和优化设计；确保该机设计美观、结构可靠、工作稳定；

    l  四缸结构的两个整体焊接机架，经应力处理后，由齐二公司大型落地镗铣床精密加工，保证四个油缸的

       贴合面和四个导轨面平行、可靠；

    l  滑块和工作台立板的四个导轨面、贴合面一次装夹加工成型，保证了机床足够的刚度、工作精度和稳定性；

       模具刀口垂直面的直线度更高；

2 液压系统

    l  德国BOSCH进口的电液伺服阀组和压力阀组，油路结构紧凑、同步精度高、

    l  双机联动时同步块控制，液压均衡、可靠，使用寿命长；

    l 下死点暂停保压功能； 

    l  油泵高压滤油器阻塞报警；

    l  超负荷安全溢流保护；

    l  工件折弯的直线度误差 1mm / 7m

5 机身

 l  在机床两端装上两个光栅尺（Y1、Y2轴），用来检测滑块与工作台的距离，光栅尺与工作台相连接，

    l  立柱变形不会影响定位，位置数据反馈到数控系统后，可以测出输出伺服阀控制信。

6 后挡料

    l  机架内档墙板上安装有滚珠丝杆、滚动导轨数控后挡料（X轴）。

    l  X轴分别安装在四个墙板的两外档内，用来控制中小型零件的多种规格尺寸的折弯定位。

    l  X轴可同步或单动，能同时加工同规格板料、不同边长（挡料尺寸不同）的工件加工。

1.The press brake consists of two horizontal integral welding frames and intermediate two connecting beams.
2.The four cylinders are arranged on the wallboard,ａnd rigid connected with block.
3.The workbench is composed of four -U adjustable wedge block,which connected with four wall boards.
4.The whole block,workbench and assembled frame consist of one load uniformly distributed,high-precision requirements of the four cylinder synchronous CNC bending machine.
5.The double linkage consists of two single machine tools and linkage block by CNC,which can be single or double operation.
6.The frame has the characteristic of good rigidity,high processing precision,good manufacturability,convenient installation and transportation.
7.Sliding block and workbench force is reasonable and uniform load.
8.Sliding block and oil cylinder connected rigidly,guaranteeing the block's synchronization accuracy in fast forward,work and return.
9.Due to the grating ruler feedback and synchronization valve control,the machine tool has strong anti-side load capabiliry.
10.Due to the adoption of CNC synchronous cards,it ensures double linkage synchronous precision by the grating ruler's synchronous feedback.
