Aluminum seamless goods are now produced in a wide range of ways, and both are in limited supply due to the high demand. This demonstrates the usefulness and need of using this information in the vast majority of situations. Continue with the most popular seamless aluminum goods - pipes - for the moment. Today, we're going to teach you how to bend seamless aluminum tubing in the proper way, so you can do it properly.
The features of the seamless aluminum pipe as a product
Aluminum tube is lightweight (about one-third the weight of steel), flexible, non-corrosive, resistant to chemical and temperature effects (working temperature is approximately +150 °C to approximately 270 °C), has high conductivity and thermal conductivity, is environmentally friendly, and has a long service life. They are distinct from one another:
Sections in the shapes of circles, squares, rectangles, and other special-shaped sections;
It is decided to use cold bending, extrusion, and welding as production techniques.
lengths that are measured, unmeasured, multi-dimensional, and boxed
A high level of chemical purity and technical purity is achieved by the chemical composition (al grade).
In this section, we will discuss the bending process and how to bend seamless aluminum tubes.
When a straight seamless aluminum tube is bent at any angle, the metal structure will deform, which means that the inner layer of the profile will be compressed and the outer layer will be stretched, resulting in the deformation of the metal structure. Fortunately, the product will suffer very little damage due to bending because of aluminum's low density and light weight. Because the alloy aluminum develops rapidly throughout the manufacturing process, tubular goods from this manufacturer will not bend as readily.
Because of their flexibility, seamless aluminum tubes may be used to install structures with the most complicated forms while still preserving the cross-section and integrity of the finished product. When it comes to the bending operation itself, basic equipment or sophisticated mechanisms are used to pre-heat the workpiece, or the workpiece is bent manually in the cold chamber. Everything is dependent on the size, kind, and structure of the product, as well as the wall thickness and the intricacy of the bending form.
For aluminum seamless (level I), there are primarily four types of bending available: bending, support, duck type, and kalach. Item with two 135-degree folding angles: This is a three fold duck; this is a bracket (90 degrees in the center and 135 degrees at the edge) and twisted into a semicircle; kalach, folded 45-135 degrees: This is a difficult piece to fold and bend. When bending, it is necessary to adhere to the following rules:
The aluminum pipe must be bent in such a way that the junction does not follow the concave or convex bending curve (that is, perpendicular to the bending surface) if it is to be welded.
If the product has a diameter of 15-20mm, the bending radius must be at least the outside diameter multiplied by two; otherwise, the product will fail.
If the workpiece diameter is more than 25 mm, the bending radius must be at least three times the outer diameter multiplied by the workpiece diameter.
