Methods to ensure effective bending and straightening of square tubes

To make the square tubes that have been processed into products have less roundness, we have to rely on the mechanical things straightening machine. Therefore, in order to eliminate the roundness of square pipes, they need to be cold straightened. The square tube detour is caused by improper adjustment of the rolling mill, residual stress during rolling and improper cooling along the tube section and length. Therefore, it is impossible to get very straight pipes directly from the rolling mill. Only after cold straightening the roundness of pipes can you satisfy the rules of technical conditions.

In order to make the square tube products processed today have less sensitivity, we must rely on the mechanical straightening machine to complete the straightening machine from east to west. Therefore, in order to eliminate the distortion of square tubes, they need to stop cold straightening. The bending of square tube is caused by improper adjustment of rolling mill, residual stress during rolling and uneven cooling along the pipe section and length. Therefore, it is impossible to obtain very straight pipes directly from the rolling mill. Only after the flexibility of cold straightening pipes can the rules of technical conditions be met.

The basic principle of straightening is to stop the elastic-plastic detour of the square tube from a large degree of detour to a small degree of detour, so it is necessary for the steel tube to be repeatedly detoured in the straightening machine. The level of steel pipe's repeated detour is mainly determined by the adjustment of the straightening machine.

The basic principle of straightening is to make the square tube undergo elastic-plastic change, from large change to small change, so the steel tube must be changed repeatedly on the straightening machine. The repeated change level of the steel pipe mainly depends on the adjustment of the straightener.

There are many factors that affect the straightening quality, such as the roundness of the original pipe, steel pipe size and data straightening model, adjustment parameters, etc.
