Introduction to the processing method of PPS plastic pipe elbow
pps塑料管弯头加工方法介绍，生产pps塑料管弯头，先列出pps塑料管弯头手工放样步骤：（以一节为例，其余方法相同）先按实际尺寸画出弯头侧面投影,包括接缝线。
The processing method of PPS plastic pipe elbow is introduced. For the production of PPS plastic pipe elbow, the manual setting out steps of PPS plastic pipe elbow are listed first: (take one section as an example, the other methods are the same) the side projection of the elbow is drawn according to the actual size, including the seam line.
按线把每一个封闭线框图形分割成***立的图形。（可以裁剪，也可以单***再画）
Each closed wireframe figure is divided into independent figures by lines. (it can be cut or painted separately)
取一个图样，（将中心线垂直的设置）画在另一张纸上，沿图样高度画两条上下平行的横线，并与中心线垂直，长度正***是图样直径的圆周长。（封闭的长方形）
Take a pattern, (set the center line vertically) on another sheet of paper, draw two parallel horizontal lines along the height of the pattern, and perpendicular to the center line, the length is exactly the circumference of the pattern diameter. (closed rectangle)
将图样垂直方向作等分，并作***标记，然后将这些等分线垂直的画到刚才画的展开的长方形内，注意展开图上的点一定要对应投影图样上的点。
Divide the vertical direction of the drawing into equal parts and mark them. Then draw the bisectors vertically into the expanded rectangle just drawn. Note that the points on the expanded drawing must correspond to the points on the projection drawing.
将图样上斜线沿水平方向作等分。并平行的拉到展开的图样上，并对应相应的点。把展开样上得到的交点圆滑连接，就是展开的曲线。等分作的越密，曲线越准。
Divide the oblique lines on the pattern in the horizontal direction. And pull parallel to the expanded pattern, and corresponding points. A smooth connection of the intersection points obtained from the developed sample is the developed curve. The more dense the bisection is, the more accurate the curve will be.
放出咬口的量，和板厚处理。弯头下料必须知道弯曲半径，厚度、几节。需要可出图。
Set out the amount of undercut and plate thickness treatment. The bend radius, thickness and several sections must be known for elbow cutting. It needs to be chartable.
