pps塑料管彎頭加工方法介紹

Introduction to the processing method of PPS plastic pipe elbow

pps塑料管彎頭加工方法介紹，生產(chǎn)pps塑料管彎頭，先列出pps塑料管彎頭手工放樣步驟：（以一節(jié)為例，其余方法相同）先按實(shí)際尺寸畫出彎頭側(cè)面投影,包括接縫線。

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.

按線把每一個封閉線框圖形分割成***立的圖形。（可以裁剪，也可以單***再畫）

Each closed wireframe figure is divided into independent figures by lines. (it can be cut or painted separately)

取一個圖樣，（將中心線垂直的設(shè)置）畫在另一張紙上，沿圖樣高度畫兩條上下平行的橫線，并與中心線垂直，長度正***是圖樣直徑的圓周長。（封閉的長方形）

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)

將圖樣垂直方向作等分，并作***標(biāo)記，然后將這些等分線垂直的畫到剛才畫的展開的長方形內(nèi)，注意展開圖上的點(diǎn)一定要對應(yīng)投影圖樣上的點(diǎn)。

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.

將圖樣上斜線沿水平方向作等分。并平行的拉到展開的圖樣上，并對應(yīng)相應(yīng)的點(diǎn)。把展開樣上得到的交點(diǎn)圓滑連接，就是展開的曲線。等分作的越密，曲線越準(zhǔn)。

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，和板厚處理。彎頭下料必須知道彎曲半徑，厚度、幾節(jié)。需要可出圖。

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.
