W12NC数控液压四辊卷板机，能将金属板料一次上料不需调头即可完成板料端部预弯和卷制成形，且在各种卷板机中剩余直边最小。该系列可卷制厚度6mm—120mm宽度2000mm-4000mm的板材。
    该系列卷板机具有以下特点：
    1、工作辊轴承采用轧机用调心辊子轴承，摩擦阻力小，动力损失少，使用寿命长，能耗低。
    2、下辊和侧辊两端的同步升降、卷锥倾斜量控制及调平均由数控系统自动控制，控制精度高。
    3、数控系统为公司自主研发，国内，具有屏幕显示、卷制计算、程序控制、工艺参数存储、软件保护与故障报警、人机对话等多项功能。
    产品广泛应用于机械、冶金、建材、化工、电子、电力、轻工等多个行业，特别在、航天、造船、机车、锅炉、桥梁、钢构等领域，产品覆盖全国，并出口亚、非、欧等国家。 

WB12K CNC 4-ROLLER PLATE ROLLING MACHINE
　　We are the largest producer for plate bending machineplate straightening machine, the max thickness for the bending machine is 260mmthe max width is more than 23m. Our max staightening thickness is more than 100mm for our plate straightening machine,  we are the drafters of this China Nation Standardａnd for the plate bending machineplate straightening machine.   This machine can do the pre-bending through horizontal moving of the two bottom rolls.it only need one feeding of metal plate to fufill the prebending of two ends.   1.The two bottom rolls are driven by separate power system,eliminating the mechanical interference, vibrationabrasion from the sliding frictions.The bearings of the rolls are self-aligning roll-bearings,with low energy consumptionnoises. The required power from the main motor is small, energysavingenvironmental protecting. 
2.The hydraulic cylinder of upender is set beneath the bed, reducing the volume of the whole machine structure. It not only reduces the spacepower ,but also enables the machine to bend the small conesdish plates,expanding its aplications. 
3.The structure of the horizontal shift unit is compactconvenient for maintenance. 
4.The synchro-lift of both ends of the up roll, the position of the all rollers, the recomended rolling timesscrewdown distance are all automatically controlled via
CNC system with high  precision. 
5.The CNC system is advance in China.It has the functions of screen displaying,bending calculation,program controlling,parameter storing.software protection.default alarmingman-machine conversation,etc.
