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.
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.
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.
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.
First, draw the side projection of the elbow according to the actual size. Including suture.
Second, the iron sheet processing plant divides each closed wireframe figure into independent figures with lines. (It can be cut or painted separately.
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
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.
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.
6、 The bite amount and thickness of iron sheet processing.
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.
