专注通风管道加工·排烟罩

White iron sheet processing is a widely used material in the market in recent years. Because of its unique product performance, it is loved by everyone.

通风管道公司指出白口铁皮加工的产品一般用于管道安装，比如我们常见的餐厅用来排油烟的通风管，还有一些供水管。因为白口铁加工的产品防锈、抗氧化、经济，所以很多管道都是白口铁施工的。

The ventilation pipe company pointed out that the products processed by white iron sheet are generally used for pipe installation, such as the ventilation pipe used to exhaust oil smoke in our common restaurants, and some water supply pipes. Because the products processed by white iron are rust-proof, anti-oxidation and economical, many pipes are constructed by white iron.

由于白口铁皮加工产品中含有锌，而锌离子是一种比较活泼的金属离子，白口铁皮加工产品表面的锌离子在与空气或水、化学品接触时，能有效地保护内部的铁和产品的质量。而且白口铁产品表面光亮，可用于管道通风设施的安装，不仅具有美观的装饰效果，在实用性能上也比其他材料更具性价比。尤其是水。铁皮加工厂家对于一些供水管道，白口铁产品可以有效防止腐蚀，所以水质可以得到保证。

Because the processed products of white iron sheet contain zinc, and zinc ion is a relatively active metal ion, the zinc ion on the surface of the processed products of white iron sheet can effectively protect the internal iron and product quality when contacting with air, water and chemicals. Moreover, the surface of white iron products is bright, which can be used for the installation of pipeline ventilation facilities. It not only has beautiful decorative effects, but also has more cost-effective performance than other materials. Especially water. For some water supply pipes, the iron sheet processing factory can effectively prevent corrosion with white iron products, so the water quality can be guaranteed.

但其实白口铁皮加工的生产工艺都差不多，只是在后期的服务和过程质量控制上。太便宜的白口铁皮加工出来的产品质量肯定略差，所以在选择白口铁加工出来的产品时，一定要注意不要比价，要先看产品质量。

But in fact, the production process of white iron sheet processing is similar, only in the late service and process quality control. The quality of the products processed from too cheap white iron sheet must be slightly poor, so when selecting the products processed from white iron sheet, we must pay attention not to compare prices, but to see the product quality first.

根据实际尺寸画出肘部的侧面投影。包括接缝线。

First, draw the side projection of the elbow according to the actual size. Including suture.

第二，铁皮加工厂将每个封闭的线框图形用线划分成独立的图形。(可以单独切割，也可以单独喷漆。

Second, the iron sheet processing plant divides each closed wireframe figure into independent figures with lines. (It can be cut or painted separately.

取一个图案，画在另一张纸上(垂直设置线)。铁皮加工厂沿着图案的高度画两条上下平行且垂直于线的水平线。长度正好是图案直径的周长。(闭合矩形

Take a pattern and draw it on another piece of paper (set the centerline vertically). The iron sheet processing plant draws two horizontal lines parallel to the top and perpendicular to the center line along the height of the pattern. The length is exactly the circumference of the pattern diameter. (Closed rectangle

铁皮加工厂将图案的垂直方向分成相等的部分，铁皮加工厂标记出来，然后将这些平分线垂直画入刚刚画出的展开的矩形。注意展开图上的点必须对应于投影模式上的点。

The iron sheet processing factory divides the vertical direction of the pattern into equal parts, marks them, and then draws these bisectors vertically into the expanded rectangle just drawn. Note that the points on the flat view must correspond to the points on the projection pattern.

沿着水平方向将图案上的对角线分成相等的部分。并且平行于展开的图案，并且对应于相应的点。在展开的样本上获得的交点的平滑连接是展开的曲线。等分越密，曲线越精确。

Divide the diagonal on the pattern into equal parts along the horizontal direction. It is parallel to the unfolded pattern and corresponds to the corresponding point. The smooth connection of intersections obtained on the unfolded sample is the unfolded curve. The closer the bisection, the more accurate the curve.

六、关于铁皮加工的咬入量，以及厚薄处理。

6、 The bite amount and thickness of iron sheet processing.

切割白口铸铁弯头时，应知道弯曲半径、厚度和截面数。钣金展开图一般采用相贯线法展开，没有计算公式。软件绘图更方便。

When cutting white cast iron elbow, the bending radius, thickness and section number should be known. The sheet metal unfolding drawing is generally developed by the intersecting line method, and there is no calculation formula. Software drawing is more convenient.
