Precautions and bending characteristics of rolling tubes

- Mar 27, 2019-

Rolling tube is a kind of pressure finishing process. It utilizes the cold plasticity characteristic of metal at normal temperature. The rolling tool is used to apply an appropriate amount of pressure to the surface of the workpiece to make plastic flow of the surface metal of the workpiece and fill it into the original residue. In the valley of the concave wave, the surface roughness of the workpiece is reduced. Due to the plastic deformation of the rolled surface metal, the surface layer is cold hardened and the grain is thinned to form a dense fibrous shape, and a residual stress layer is formed, and the hardness and strength are increased, thereby changing the corrosion resistance and the compatibility of the surface of the workpiece. . Rolling is a non-cutting plastic working method.

What should I pay attention to when buying a rolling tube?

The rolling tube has high tolerance and dimensional accuracy, the product precision is controlled at ±5mm, the inner and outer wall finish is good, and the surface has no oxide layer. The thin-walled rolling tube has excellent comprehensive performance and can withstand high pressure. It can be cold-bent, flared and flattened without cracking, wrinkle-free skin, and can be used for various complex deformations and mechanical processing.

The promotion and application of precision seamless steel tubes can save steel, improve processing efficiency, reduce processing steps and equipment investment, save costs and greatly save machining time, increase production capacity and material utilization rate, and at the same time help improve product quality and reduce costs.

Thin-walled rolling tubes have tensile, compressive and bending resistance properties, so when choosing precision seamless steel tubes, they should also be considered from these aspects. For the performance selection of precision seamless steel tubes, tensile strength is the most fundamental attribute. Thin-walled rolling pipe is widely used in many fields such as industry, construction and furniture because of its good tensile performance. Precision seamless steel tubes with strong tensile strength are most favored by the purchaser. Of course, precision seamless steel pipes have other characteristics, namely, bending resistance and compression resistance, which also make it applicable to other
