W12NC數(shù)控液壓四輥卷板機(jī)，能將金屬板料一次上料不需調(diào)頭即可完成板料端部預(yù)彎和卷制成形，且在各種卷板機(jī)中剩余直邊最小。該系列可卷制厚度6mm—120mm寬度2000mm-4000mm的板材。
    該系列卷板機(jī)具有以下特點(diǎn)：
    1、工作輥軸承采用軋機(jī)用調(diào)心輥?zhàn)虞S承，摩擦阻力小，動(dòng)力損失少，使用壽命長(zhǎng)，能耗低。
    2、下輥和側(cè)輥兩端的同步升降、卷錐傾斜量控制及調(diào)平均由數(shù)控系統(tǒng)自動(dòng)控制，控制精度高。
    3、數(shù)控系統(tǒng)為公司自主研發(fā)，國(guó)內(nèi)，具有屏幕顯示、卷制計(jì)算、程序控制、工藝參數(shù)存儲(chǔ)、軟件保護(hù)與故障報(bào)警、人機(jī)對(duì)話等多項(xiàng)功能。
    產(chǎn)品廣泛應(yīng)用于機(jī)械、冶金、建材、化工、電子、電力、輕工等多個(gè)行業(yè)，特別在、航天、造船、機(jī)車(chē)、鍋爐、橋梁、鋼構(gòu)等領(lǐng)域，產(chǎn)品覆蓋全國(guó)，并出口亞、非、歐等國(guó)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.
