W11-6×1600卷板机设计要求
该卷板机结构形式为三辊对称式,上辊在两下辊中央对称位置通过锥齿轮传动作垂直升降运动,通过主减速机的末级齿轮带动两下辊齿轮啮合作旋转运动,为卷制板材提供扭矩。规格平整的塑性金属板通过卷板机的三根工作辊(二根下辊、一根上辊)之间,借助上辊的下压及下辊的旋转运动,使金属板经过多道次连续弯曲,产生永久性的塑性变形,卷制成所需要的园筒、锥筒或它们的一部分。该卷板机主要有一个上辊、两个下辊、机架及驱动电机传动机构等部分组成。
本设计要求对该型卷板机做总体设计和上辊、下辊和机架等机构做结构设计。
原始数据:1.最大卷板厚度:6mm
2.最大卷板宽度:1600mm
3.卷板速度:7.52m/min
4.满载卷板最小直径:∮350mm
5.上辊直径:∮160mm;下辊直径:∮150mm;两下辊中心距:210mm
6. 板材屈服极限:245MPa
技术要求:
1. 该机结构形式为三辊对称式,上辊在两下辊中央对称位置作垂直升降运动,通过丝杆螺母蜗杆转动而获得,两下辊作旋转运动,通过减速机的输出齿轮与下辊齿轮啮合,为卷制板材提供扭矩;
2. 卷板机运行要平稳、可靠,要有良好的整体结构刚度;
3.结构整体要有较高的强度和抗冲击性能。
摘 要
卷板机是一种将金属板材弯卷成筒体、锥体、曲面体或其他形体的通用成型设备,广泛应用于石油、化工、机械制造等领域。近年来, 随着煤炭需求量的增加,市场对矿用提升机、输送机、支架等矿用设备的需求,无论从质量和数量上,都有了更高的要求,滚筒等弧形或圆筒形矿用产品的需求量也日益加大。
卷板机是一种将金属板材卷制成筒形、弧形或其它形状工件的通用设备。根据三点成圆的原理,利用工作辊相对位置变化和旋转运动使板材产生连续的塑性变形,以获得预定形状的工件。
关于卷板机的分类,国外一般以工作辊的配置方式来划分。国内普遍以工作辊数量及调整形式等为标准实行混合分类,一般分为:
1)三辊卷板机:包括对称式三辊卷板机、非对称式三辊卷板机、水平下调式三辊卷板机、倾斜下调式三辊卷板机、弧形下调式三辊卷板机和垂直下调式三辊卷板机。
2)四辊卷板机:分为测辊倾斜调整式四辊卷板机和侧辊圆弧调整式四辊卷板机。
3)特殊用途卷板机:有立式卷板机、船用卷板机、双辊卷板机、锥体卷板机、多辊卷板机和多用型卷板机等。

ABSTRACT
Three-roller plate bending machine can bend plate to a special shape, such as colum,cone,camber and so on,which is widely applied to boiler manufacture,chenical industry and machine manufacture.Near years, colum,cone,camber can be used to internet ,belt conveyer,hoist foundation ect. In For this purpose,a class of Roll Machine has been developed in order to improve the productivity,decrease the work intensity and content the demand of the factory for plate coiling.
Machine is a roll of sheet metal bent to cylindrical, curved shape of the work piece or other common devices. According to the principle of three-point into a circle, making use of changes in the relative positions of roller and rotation so that producing a continuous sheet of plastic deformation, is scheduled for the shape of the work piece.
On the machine classification, in order to work abroad, the general approach to roll into the configuration. General domestic work and adjust the volume roll form, such as mixed as the standard classification, generally divided into:
1) three-roll Rolling Machine: Including Three Roller Symmetrical Rolling Machine, Three Roller Asymmetrical Rolling Machine, horizontal three-roll machine down, tilt down Three Roller Rolling Machine, Three Roller downward arc Machine cut and the vertical three-roller machine.
2) four-roll Rolling Machine: measuring roll is divided into four-roller tilt adjustment and side-roll Rolling Machine Arc-adjusted four-roller machine.
3) special-purpose Rolling Machine: A Vertical Rolling Machine, Rolling Machine marine, twin-roll Rolling Machine, Cone Machine, multi-roll Rolling Machine and Rolling Machine, such as multi-purpose type.
KEY WORDS:rolling machine sheet metal molding equipment
