用圖解来計算圓形压延零件的展开尺寸,不需要进行繁杂的演算,应用起来十分方便。只要圖做得足够准确,得出的結果就不会同計算所得的結果有什么差別。如果压延零件尺寸很大,可以把它的尺寸縮小几倍后再做圖。相反的,如果压延零件很小,也可以把它的尺寸放大几倍后做圖。放大和縮小的倍数可以根据压延零件的具体情况来决定。 Calculating the unfolded dimensions of a circular calendered part with a diagram does not require complicated calculations and is very easy to apply. As long as the map is sufficiently accurate, the results obtained will not differ from the calculated ones. If the calendered part is large in size, you can reduce the size a few times before making the picture. Conversely, if the calendering part is small, you can also enlarge the size of its size several times after the drawing. The magnification and reduction multiples can be determined according to the specific circumstances of the rolling parts.
