该机结构型式为四辊式，上辊为主传动，通过减速机的输出齿轮与上辊齿轮啮合，为卷制板材提供扭矩；通过液压缸内的液压油作用于活塞，使下辊作垂直升降运动，以便夹紧板材；在下辊的两侧设有侧辊，通过丝杆螺母蜗轮蜗杆传动，使侧辊沿着机架导轨作倾运动，以弯卷板材；该机优点是板材端部预弯及卷圆可以在同一台设备上进行。 w12系列四辊卷板机技术参数 型号 | 卷板最大厚度(mm) | 卷板最大宽度(mm) | 卷板 速度m/min | 预弯板厚 mm | 满载卷板最小直径(mm) | 上轴直径(mm) | 下轴直径(mm) | 侧轴直径(mm) | 主电机功率(kw) | 重量 t | 外形尺寸 长*高*宽mm | 8x2000 | 8 | 2000 | 6.1 | 6 | 700 | 280 | 260 | 180 | 11 | 8.6 | 5300x1400x1760 | 8x2500 | 8 | 2500 | 6.1 | 6 | 750 | 300 | 280 | 230 | 15 | 9.4 | 6100x2000x2070 | 12x2000 | 12 | 2000 | 5.45 | 10 | 700 | 300 | 280 | 230 | 15 | 16.5 | 5600x2000x2070 | 12x2500 | 12 | 2500 | 5.5 | 10 | 750 | 340 | 300 | 260 | 22 | 16 | 6300x2000x1200 | 12x4000 | 12 | 4000 | 4 | 10 | 850 | 380 | 340 | 280 | 30 | 28.5 | 7600x2000x1800 | 16x2000 | 16 | 2000 | 5.5 | 12 | 750 | 340 | 300 | 260 | 22 | 17.5 | 5800x2000x1800 | 16x2500 | 16 | 2500 | 6.5 | 12 | 850 | 350 | 320 | 280 | 30 | 26 | 6800x2000x1870 | 20x2000 | 20 | 2000 | 6.5 | 16 | 850 | 350 | 320 | 280 | 30 | 24.5 | 6000x2000x1850 | 20x2500 | 20 | 2500 | 6.5 | 16 | 1000 | 400 | 380 | 320 | 37 | 32 | 6850x2000x2070 | 20x3000 | 20 | 3000 | 4.5 | 16 | 1100 | 450 | 420 | 350 | 45 | 41 | 7300x2100x2200 | 25x2000 | 25 | 2000 | 6.5 | 22 | 1000 | 400 | 380 | 320 | 37 | 35 | 6300x2200x2030 | 25x2500 | 25 | 2500 | 5 | 22 | 1100 | 450 | 420 | 350 | 45 | 45 | 8000x2600x2100 | 25x3000 | 25 | 3000 | 5 | 22 | 1150 | 540 | 450 | 380 | 55 | 52 | 9000x3200x2500 | 25x4000 | 25 | 4000 | 4 | 22 | 1200 | 540 | 500 | 450 | 63 | 62 | 10100x3500x2900 | 30x2000 | 30 | 2000 | 5 | 25 | 1100 | 450 | 420 | 350 | 45 | 40 | 7500x2600x2500 | 30x2500 | 30 | 2500 | 4.5 | 25 | 1150 | 480 | 460 | 380 | 55 | 52 | 8400x2590x2600 | 30x3000 | 30 | 3000 | 4 | 25 | 1300 | 560 | 520 | 420 | 60 | 61 | 9200x3500x2900 | 30x4000 | 30 | 4000 | 4 | 25 | 1500 | 650 | 600 | 480 | 60 | 75 | 10200x3500x2900 | 40x2000 | 40 | 2000 | 4.5 | 36 | 12000 | 520 | 500 | 400 | 45 | 60 | 8200x3000x2500 | 40x2500 | 40 | 2500 | 4 | 36 | 1300 | 560 | 520 | 420 | 60 | 65 | 8700x3500x2900 | 40x3000 | 40 | 3000 | 4 | 36 | 1500 | 650 | 580 | 480 | 75 | 95 | 9200x3600x3000 | 40x4000 | 40 | 4000 | 3.5 | 36 | 1800 | 710 | 650 | 500 | 86 | 120 | 12500x4000x3500 | 50x2000 | 50 | 2000 | 4 | 45 | 1500 | 650 | 580 | 480 | 60 | 86 | 8500x3500x3000 | 50x2500 | 50 | 2500 | 4.5 | 45 | 1550 | 680 | 620 | 500 | 75 | 96 | 9000x4000x3300 | 50x3000 | 50 | 3000 | 4 | 45 | 1800 | 720 | 650 | 520 | 90 | 110 | 9800x4300x3500 | 60x2500 | 60 | 2500 | 4 | 50 | 1800 | 700 | 650 | 500 | 90 | 108 | 9500x4500x3700 | 60x3000 | 60 | 3000 | 4.5 | 50 | 1800 | 750 | 710 | 560 | 121 | 135 | 10000x4500x3800 |
