WB12K數控液壓四輥卷板機

　　W12NC數控液壓四輥卷板機，能將金屬板料一次上料不需調頭即可完成板料端部預彎和卷制成形，且在各種卷板機中剩余直邊最小。該系列可卷制厚度6mm—120mm寬度2000mm-4000mm的板材。
    該系列卷板機具有以下特點：
    1、工作輥軸承采用軋機用調心輥子軸承，摩擦阻力小，動力損失少，使用壽命長，能耗低。
    2、下輥和側輥兩端的同步升降、卷錐傾斜量控制及調平均由數控系統自動控制，控制精度高。
    3、數控系統為公司自主研發，國內領先，具有屏幕顯示、卷制計算、程序控制、工藝參數存儲、軟件保護與故障報警、人機對話等多項功能。
    產品廣泛應用于機械、冶金、建材、化工、電子、電力、輕工等多個行業，特別在軍工、航天、造船、機車、鍋爐、橋梁、鋼構等領域，產品覆蓋全國，并出口亞、非、歐等國家。 

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.
