天圆地方不锈钢钣金放样下料方法

1.先实际尺寸画出侧视图和俯视图,然后把俯视图上的1/4圆弧等分成3份。再把分出的各点(1234)用直线(abcd)F点相连。(步骤相对应1-1图与1-2图)

2.再画一条直线,取一点I,量取高度尺寸以I点为起点在直线上标注一点J。然后过I点画一条与其垂直相交线,量取直线a的长度以I点为起点在线上标注一点K,再量取直线b长度以I点为起点在直线标注一点L 。用直线eK J两点相连,再用直线fL J两点相连 。(步骤相对应1-3图)

3.① 以方头一边的长度画出一条P Q直线,找出P Q直线中心点O画一条与其垂直相交线。

② 以点Q为圆心,直线e为半径(以下称Qe圆弧)在垂直相交线上画圆弧相交于点7,用直线把7 Q两点相连。

③ 以点Q为圆心,直线f为半径画圆弧(以下称Qf圆弧)。再量取俯视图中的点1与点2之间的弦长(以下称12弦长)为半径,点7为圆心画圆弧相交于点6,用直线把6 Q两点相连。

④ 以点6为圆心,12弦长为半径画圆弧与Qf圆弧相交于点5,用直线把5 Q两点相连。

⑤ 以点5为圆心,12弦长为半径画圆弧与Qe圆弧相交于点4,用直线把4 Q两点相连。

⑥ 以点Q为圆心,线段PQ为半径画圆弧,再以点4为圆心,线段7Q为半径画圆弧相交于点S,用直线把Q S两点相连。再用直线把点4与点S相连。

⑦ 以点S为圆心,线段Q4为半径画圆弧(以下称S4圆弧),再以点S为圆心,直线f半径,画圆弧(以下称Sf圆弧)。

⑧ 以点4为圆心,12弦长为半径画圆弧与Sf圆弧相交于点3,用直线把3 S两点相连。

⑨ 以点3为圆心,12弦长为半径画圆弧与Sf圆弧相交于点2,用直线把2 S两点相连。

⑩ 以点2为圆心,12弦长为半径画圆弧与S4圆弧相交于点1,用直线把1 S两点相连。

4.以点4为圆心,点O4之间的距离为半径画圆弧(以下称O4圆弧),再以点S为圆心,O Q两点的长度为半径(即是1/2边长)画圆弧与O4圆弧相交于点T,用直线把S T两点相连,再用直线把点1与点T相连。(步骤相对应1-4

5.用线段把1 2 3 4 5 6 7依次连接,即得1/2展开图。(步骤相对应1-4

6.如要完整展开图即可按以上步骤连续把另一半展开图画出(步骤相对应1-5
