卷板机的技术规格常标注在机器的铭牌上。例如:20×2000mm的卷板机,是指该机所能弯卷板材的最大厚度为20mm,最大宽度为2000mm,板材的材质一般以Ⅱ号钢类(A3,A4,20,25号钢)的常温状态为准。使用厂在弯制钢材时,常常不局限于这一类钢种,工件有时也不处在常温状态,尤其是工件的宽度、厚度经常变动。为了在同一台弯板机上能加工不同强度、不同厚度的工件,充分发挥机械设备的潜力,绘制卷板机的技术特性曲线就很有必要。本文介绍这种曲线的绘制和应用。
Bending machine specifications often marked on the machine nameplate. For example: 20 × 2000mm Bending Machine, which means that the machine can be bent plate maximum thickness of 20mm, the maximum width of 2000mm, the plate material generally Ⅱ steel (A3, A4,20,25 steel) The room temperature prevail. When using the factory in bending steel, often not limited to this type of steel, the workpiece is sometimes not at room temperature, especially the width of the workpiece, the thickness often changes. In order to be able to process different strength and different thickness of workpieces on the same bending machine, it is necessary to give full play to the potential of mechanical equipment to draw the technical characteristics of the bending machine. This article describes the drawing and application of this curve.
