圆环形平板工件如图1,在材料准备上,当尺寸较小时.通常用切割器整体下料:当尺寸较大时,通常由多等分弧板拼接对焊而成,这样可节省大量的材料,从而降低生产成本。1.圆环形平板等分拼接时备料尺寸的通用公式设圆环形平板工件备料要求外径为D,内径为d,钢板厚度为δ.并设该板由n等分(n≥2)拼接而成,所需材料最小长度为L、最小宽度为B。根据图2可求得:L=n·b+(n-1)·s+c(1)式中s一切割钢板的割缝宽度
Circular flat-plate workpiece shown in Figure 1, in the material preparation, when the size is small, usually cutting the overall cutting material: When the size is large, usually by multi-equal arc splice butt welded together, this can save a lot Of the material, thereby reducing production costs. 1. Circumferential annular splice splicing size of the general formula set circular annular workpiece preparation requirements of the outer diameter D, diameter d, the thickness of the plate δ and set the plate by n equal (n ≥ 2) Spliced together, the required minimum length of material L, the minimum width of B. According to Figure 2 can be obtained: L = n · b + (n-1) · s + c (1) where s a cutting kerf width
