大尺寸法兰类零件(外径大于500mm)毛坯的制造,由于受原材料尺寸的限制和为了节约原材料,一般采用分段下料,拼焊制造。为制造方便,分段大多采用等分法。例如,等分为三段或者四、五、六段等排料。当根据图样已知零件的外圆半径E、内圆半径r,初定了等分段数n时,零件排料所需要板材的最小宽度B_(min),最小长度L_(min)是多少呢?只有知道了最小宽度B_(min),最小长度
Large-size flange parts (diameter greater than 500mm) rough manufacturing, due to the constraints of the size of raw materials and in order to save raw materials, the general use of sub-cutting, welding manufacturing. For ease of manufacture, the sub-divided mostly used. For example, equally divided into three paragraphs or four, five, six paragraphs such as nesting. When the radius of the outer circle E, the inner circle radius r, and the initial number of equal sections n are known according to the drawing, what is the minimum width B min and minimum length L min of the sheet that the part needs to discharge? Only know the minimum width B_ (min), the minimum length
