    冷弯型钢设备中辊轮形状的设计要求
    发布来源:http://www.jnjgcg.com/  2017-5-4 11:17:51 发布人:济南坚固彩钢
    冷弯型钢是一种通过冷弯成型工艺制得的产品,其成型效率关键是取决于冷弯型钢设备,包括它的辊型和结构。目前来说,用的更多的是成型辊,所以成型辊轮形状的确定就成了冷弯成型过程中更复杂的问题。
    By cold bend section steel is a kind of cold bending forming process of product, its forming efficiency is the key depends on the cold bending steel equipment, including its roll shape and structure. At present, the most commonly used is the molding roll, so the certainty of the shape of the shape of a roll wheel is the most complicated question in the process of cold bending.
    在设计冷弯型钢设备的辊轮形状的时候,以利用更少道次为前提的情况下,辊轮形状应使材料有均匀和合理的变形。同时,应根据所选定的在各道次中不变的中心轴线,对辊轮外形的竖向及横向尺寸进行确定和计算。
    In the design of cold bend section steel equipment of the roller shape, on the premise of using the least passes, the roller shape should make materials with uniform and reasonable deformation. At the same time, the vertical and transverse dimensions of the roll wheel should be determined and calculated according to the fixed axis of the central axis which is selected.
    通过每一对辊轮的时候,型钢壁的弯曲角度不能超过规定范围,否则产品的品质会受影响。当弯曲内径很小的时候,为了使材料弯曲容易并标定弯曲线的位置,可预先在带料上冷辊轧出向轮廓内凹进的槽。
    Through each pair of roller, the bending Angle of the wall of the section cannot exceed the specified range, otherwise the quality of the product will be affected. When the bending inner diameter is very small, in order for the material to bend easily and the position of the bending line, it can be rolled out into the groove in the outline in front of the belt.
